Without a thermometer, temperature, and handle the relationship

In work and life without a thermometer, often with the hand to feel the temperature, now I will tell you that the relation between is convenient for you to estimate the temperature. 1. Tested part temperature at 0 degrees or so, fingers felt cold, if long time continuous touch, can produce a kind of the piercing pain; 2. When the temperature of the tested parts at around 10 degrees, feel cooler, but generally can endure. 3. When the temperature of the tested parts at around 20 degrees, feel a little cool, as the extension of exposure time, can feel increasingly feel warm; 4. When the temperature of the tested parts is around 30 degrees, feel is lukewarm comfort; 5. When the temperature of the tested parts is around 40 degrees, such as touch high fever patient; 6. When the temperature of the tested parts is around 50 degrees, feel is very hot, contact for a long period of time will have sweat feeling; Scalded skin 55 degrees Celsius, is the critical temperature is more than 55 degrees Celsius can burn skin. 7. When the temperature of the tested parts at about 60 degrees, the feel is very hot, general can tolerate 10 seconds; 8. When the temperature of the tested parts at 70 degrees or so, fingers tolerance only 3 seconds, a burning sensation, and contact site soon turn red; 9. When the temperature above 80 degrees, the tested part can only touch, and the pain intensified, Spicy fire) , if you touch a long time, can produce burns. Inspection method: with the right hand index finger, middle finger and ring finger together, with its refers to the section in the back of the parts with the method of the elastic by tapping the touch surface under test, concluded that nondestructive injury occurs to the skin, can use their fingers to conclude that temperature. We first to get to know some knowledge of some of the human body temperature, most Internet users should know the body's core temperature at about 37 ℃, but human body surface temperature is not so high, when temperatures or we will not put the thermometer under his arm. Contact with tablet longest organ nature is our palms, according to different people and different seasons, the surface temperature may float between 30 and 32 ℃, and then it perceived comfortable temperature range for the 22 to 38 ℃, for the test, if the surface temperature of the tablets can be controlled within 38 ℃ then we can call it comfortable, or conversely. Laptop/tablet or mobile handheld devices, such as general requirements product surface temperature cannot exceed 40 degrees.
