The maximum of the thermos bottle



At this point, a frequently asked question is: "if the thermos flask is so good insulation, so how to cool the spacecraft?" Spaceship accumulation of heat from its electronic equipment, fuel cell, the rocket engine and the received solar radiation, etc.. All of these heat must have a place to go, otherwise the spacecraft will overheat. However, the spacecraft is a hot water bottle floating in the world's largest (in the vacuum of outer space). Then the space ship how to deal with it extra calories?

The original heat dissipation is a very important part of the space ship design process. For example, if you look at this page, you will see Skylab (Space Experiment Station) with a gold plated coating, used to reflect the infrared radiation from the sun, there is also a large radiator to dissipate the heat. Space radiator can only use infrared radiation to dissipate heat, so it must be a radiator on earth than similar large many. In the face of the earth, convection plays a main role in the cooling process, so almost all radiator use a fan to enhance convection effect. Similarly, the medial space ship cargo port door is also provided with a radiator. Once the spacecraft into orbit, one of the things the staff the first thing to do is to open the door of the radiation.

Some research institutions for the chemical analysis of Sheng 98 days five pounds in boiling water hot water flask wall furring, heavy metals contained amount of cadmium were 0.034 mg, Pb 0.12 mg, iron 24 mg, 0.21 mg and 0.44 micrograms arsenic, mercury. The scales have the possibility to increase the concentration of heavy metals in drinking water. When using a thermos flask scale change containing other liquid, especially plum juice, beer and other acidic liquid, some heavy metal elements in the scale of the precipitates due to chemical reaction, dissolved in water or other liquid to. When people long-term small put these heavy metals intake, it may cause the human digestive, respiratory and nervous system, hematopoietic lesion and dysfunction. So, on this scale must not look down upon! Therefore suggested that people should regularly to eliminate this kind of scale.

Action 2
The left hand back swing, also left knees forward elevation, toes pointed downward, the thigh is parallel to the floor. A good activities of scapula, the arm back dramatically swing.
Action 3
Put forward to raise the left foot kick backward, at the same time, placed behind the left hand swinging forward, feeling the tension buttock and thigh muscle, while the left foot greatly back kick.
Action 4
The right hand and right foot to do the same action, repeat 2 ~ 3 times. Note hands to swing at the same time, don't bend, otherwise they will be back.
Three, consciousness the body dry, correct posture
1, stand tall
Correct posture: heel, buttocks, back close to the wall, so that it is in the same line.
In the case of without walls:
Don't and ears shoulders in the same line, shoulder should be in position behind the ears;
The ears and the thumb in the same line.
2, error 1: hands forward posture
The hands forward, shoulder will relax, to the inside huddled together, Hanxiong humpback, the back line.
3, error 2: neck forward posture
The hunchback and neck habitual forward, this position will increase the burden of neck, easy to cause periarthritis of shoulder. But, often bend it, also can cause a heavy burden to the spine.
Four, through the thermos flask fall to determine the location of the body bad habits
The thought of their actions on the bottle, the result is falling down. It is usually not notice the body bad habits and body posture is not caused by the.
1, thermos flask forward slip
The hunchback, neck forward, back to the accumulation of fat, abdominal easily uplift, man, thermos flask easily forward slip. They are easily Hanxiong humpback, need to consciously open chest, chest abdomen, open the shoulders, the shoulders open ear rear position.
2, thermos flask from slipping backward
Undershot, pelvic tilt backward, forward abdomen easily raised, thermos flask easily from slipping backward. Because of their body weight in the back, often inadvertently put forward uplift belly, like an old man. They need to tighten the lower jaw, consciously put the body center of gravity on the trunk of the body center of gravity, correct.
3, thermos flask to the left and right sliding direction, distorted body know
There is a shoe sole wear is particularly serious, low shoulder, standing, the body center of gravity on one foot and so on human body to the right and left, distort the possibility is very large. Therefore, to consciously adjust the center of gravity of the body, until the thermos flask does not fall far to the right and left.
Correction method:
The tensile side of the body, can be easily corrected body around the distortions are not the problem. Stand up straight standing, legs open, and shoulder width. Hands high above his head, grabbed the other hand at the wrist with one hand around the side of the body, stretching. If you feel pain, that muscle rigidity of the parts of the. Insist to take exercise, can correct the distorted problem of body.
Supplement: why to use thermos flask?
1 benefits
If the wrong practice of actions, not only can not achieve the slimming effect, also may have the opposite effect. However, only in their own words is very difficult to judge correctly. Therefore, the thermos flask on the head, if thermos flask slide down, can detect its movement error.
2 benefits
If the thermos flask on the head, can feel moderate weight and a sense of security, more aware of their body axis where. Usually installed half the water in 500 ml of thermos flask, namely 250 ml.
