Principle? Why dumped after use in order to make the mercury drops? Thermometer is a mercury thermometer. Its upper part is a glass tube, the lower end of a glass bulb. And the lower end of the bubble in the tube containing pure mercury, tube marked with a temperature scale. As the highest body temperature does not exceed 42 ℃, the minimum of not less than 35 ℃, so the thermometer scale is 35 ℃ to 42 ℃, each small cell represents 0.1 ℃. When the "test table," the lower end of the glass bulb thermometer and human contact, because the body temperature higher than the temperature thermometer, the bulb of the mercury by the action of heat coming from the body, volume expansion, rises along the slender glass tube, Until mercury same temperature and body temperature up. The structure is very special thermometer, the glass bulb and thin tube connecting the place, there is a very fine necking. When the thermometer leave the human body, mercury cold shrink, shrink the mercury in the mouth off, back above the mercury does not come back, so the thermometer leave the human body can continue to display the body temperature. So dumped after use in order to make the mercury thermometer dropped 2. Why is the reading, since the glass colorless trigonous. Water silver gray with silver white, but the mercury fine, color is extremely difficult to observe, which resulted in a reading difficulties. To solve this problem, the upper portion of the thermometer formed a triangular cross-section, the cylindrical surface of the cylinder. Thus, by the side of the triangular prism reflection refraction of light from mercury out of place in the junction of glass and air, and zoom, easy reading. 3. The electrical sensing device conversion principle is how some typical sensor and principle: Pressure sensors: the use of certain crystals when it is a direction compressive deformation, in a direction perpendicular to both ends of the force will produce a corresponding The voltage of the phenomenon (the piezoelectric effect) will be subject to deformation is converted into a voltage; or the use of force after the varistor resistor change will happen, it will force change converts resistor circuit, resulting in a corresponding electrical signal . The sensor used on electronic scales. Optical sensor: the so-called light-sensitive devices such as photovoltaic cell (later by the light at the output provides a constant current) or photoresistor, photodiode and transistor (internal resistance change after by light) to convert light signals into electrical signals. Infrared alarm sensor used. Temperature sensors: thermistor (temperature change resistor changes) or PN junction semiconductor material at different temperatures can cause changes in the conduction properties of temperature transmitter, such as an electronic thermometer that is the type of sensor, but a temperature above 100 degrees, the semiconductor temperature sensor should not be used, plant common thermocouple sensor using two different metal wires or pieces connected together to form a so-called "thermocouple", when the junction temperature rises two metals generated between a potential (thermoelectric power), measuring the electrical potential, the junction temperature can be learned, it is also a thermocouple temperature sensor. Displacement sensors: cause a change in the medium when the displacement position or the position between the two electrodes to form a capacitor electrode; caused by the position or displacement of two adjacent coils (the degree of coupling) is changed, the detected change in capacitance or coil inductance, mutual inductance the amount of change, it reflects the situation of displacement. Shock sensor: course using a piezoelectric effect to detect vibration, it is also possible by the electromagnetic induction, a coil so that the vibration transmitted to the movement for cutting magnetic lines in a magnetic field, the vibrations into electrical signals (electromagnetic transmitter) ; the shock passed a capacitor electrode, so that changes in capacity with shock, resulting electrical signal (electret microphone - on the use of mobile phones and other miniature microphone) These are of vibration sensors. The magnetic field sensor: Some material there is a phenomenon, when magnetic field lines in a certain direction through the material is changed (ie, the magnetic field strength is changed), it will produce a voltage along the direction perpendicular to the magnetic field lines, a phenomenon known as the Hall effect , the use of this effect can be made sensitive to the magnetic field sensor. As wind speed sensors, flow sensors, basically use some of the principles mentioned above work, not enumerate. 4. Why thermometer before use to Shake Simply put, the minister thermometer period of triangular prism, glass thickness. In the middle of the narrow tube; the lower part is shorter. The mercury bulb filled with mercury inside the bulb. On, after a bend between the next two and a very fine passage in direct communication. Therefore, this design makes the thermometer after leaving the body, even if the temperature drops, but still retains its reading the indication of the maximum temperature (vacuum formed in a very thin channel), it does not decrease with decreased ambient temperature (only with increasing rise, see references specific reasons, inconvenient repeat here) That is, in the absence of external forces swinging thermometer (using centrifugal force), the reading will rise not fall, so each must get rid of reading before using to ensure the measure accurate. [Related question] why sometimes both ears were measured, the temperature will vary a lot? Ears of temperature, as long as in the absence of severe inflammatory conditions should be similar to within O.5 ° c can accept, if the difference is too large may have Several reasons: 1 operating mode is not correct, when you use to pull the outer ear backwards and upwards, so that the ear canal form a straight line. 2 earmuffs broken or unclean. 3 external auditory canal infection leads to swelling of the tympanic membrane, the temperature will be high. 4 one ear pressure. Home use temperature measurement temperature, and why the hospital is not the same amount? Person's body temperature is not a fixed value, the temperature within one day there may be dozens of changes, even if the fever is also true. The amount of difference at home and hospital volume values ??may be changes in the level because different measurement methods, or the child's temperature has varied over time occurrence caused. Other parts of the ear moderate amount of body temperature - why? Temperature of the human body due to different positions, to accept the body Wenzhong Shu heat conduction time there are differences. In addition, other factors also affect the measured values. When measuring oral temperature, if cold before serving hot food, or mouth breathing, will affect the measured values; and axillary temperature only measured skin temperature of the surface and can not know the core temperature. A second ear thermometer thermometer safe? One second thermometer has a rigorous inspection by Japanese medical equipment, and medical devices have to admit designation, not only safe and secure, and will not let the baby feel resistance. Operation is very simple, as long as the temperature head inserted into the ear canal, can the exact temperature, will not hurt the ears will not feel uncomfortable, even sleeping temperature, the baby will not be feeling. Its operating principle is the same as the camera, when you press the temperature button, the camera shutter will fight, and receives infrared heat generated by the eardrum and surrounding tissue inside, and then the microcomputer to calculate the temperature of the wafer, is displayed. What is fever? A few degrees above body temperature is considered fever? In simple terms, fever is a process within the body's immune response, when the body is subjected to pathogen infection, can cause the body's cells to produce antibodies to be resistant, while the antibody with the blood circulation in the body control center caused the temperature to rise. In other words, the fever is not a disease, but the body defense system started to warn, remind us that the body has been infected. When the temperature is usually higher than 38 ° c, we considered a fever. Fever will not burn my mind? Only when the temperature is above 40 ° c or more, because the body will change the protein, and the cell functions and thus reduce the various factors, and thus hinder the body of many important physiological functions, this time will be on the body (especially the brain) damage. So a slight fever (38.5 ° c or less) does not need to panic, but if the temperature continues to rise, it should ask the doctor immediately for treatment. Baby fever is not going to see the doctor immediately? How else to deal with? Temperature above 38.5 ° c or cramps and so it must go to the hospital for treatment as soon as possible. Its hasty rush to make baby more uncomfortable, or increase the chance of infection in hospitals other diseases, it is better to take care of at home. Appropriate treatment according to the method provided in this manual, you can make your baby more comfortable, or if the temperature can not be lowered, you should seek medical help. Can I take a bath when the baby fever? Can you go? Many people think that a child has a fever he must be airtight package was, in fact, is wrong, it should let the baby ventilation fever, baby do not wear too much or wear gas-tight clothes, wash in warm water can help bring down a fever, every time bath for 10-15 minutes, in fact, according to the temperature rise of the number of frequencies, typically in about 4-6 hours at a time, this approach allows the skin surface blood vessels to dilate, to play a better cooling effect. Try not to let the fever children to public places, so as not to infect other diseases. When the baby fever, which should not rush fever? Here I want to re-emphasize that fever is not a disease, but a symptom of many diseases. Fever does not mean that the disease has been good, sometimes forced fever but will not be taken lightly, that disease is cured, and once efficacy after, still sick or have a fever again. So the most important thing is to find the source of the disease, the right medicine, the disease is cured naturally burn back. Eat antipyretics purpose is to let the baby a little uncomfortable, and can not be rapid cooling. The amount of time fever long body? Body temperature was measured once every four hours most appropriate and record the measurement results and other symptoms, in order to provide a reference when required to the hospital. If the baby sleep soundly at night, there is no need to wake his temperature, as long as a second ear thermometer can measure body temperature, but do not wake the baby. Determine whether the baby fever can learn in two ways: when the temperature is higher than 38 degrees ◆ Typically, we defined as fever ◆ due to cyclical changes in temperature day and night, the baby's normal body temperature can occasionally be higher than the value mentioned above, but This does not make the child feel uncomfortable, and the temperature will not last long. ◆ The body temperature is higher than 38-39 degrees, may have been infected with the disease on behalf of, but some of the infected children and does not increase body temperature (heat source may be due to poor response or so severe infection, affecting the operation of the temperature control), so In addition to measuring the temperature outside parents should also pay attention to the child's performance and usually what is the difference, especially if tired, unresponsive and so on. Traditionally it was assumed that the fever from 37.4 degrees, if the child's mental health and their performance with the usual no difference, as long as the children drink more water if you need medical attention or persistent abnormalities identified.
