在大多数使用外部加热或冷却的压力容器进行的高压实验中,人们通常在液槽(该液槽用作压力容器的低温恒温器或高温恒温器)内部测量温度,或者在压力容器外壁上测量温度。但是,由于存在温度梯度,所以按这些方法测得的温度和压力容器内部的真实温度并不相等。为了精确测量该温度,须在压力容器内部放入一个铂电阻温度计。不过,在这种场合下,必须将电阻温度计密封起来,以防止液体
In most high pressure experiments using externally heated or cooled pressure vessels, the temperature is usually measured inside the tank, which is used as a cryogenic or thermophile for pressure vessels, or on the outside of the pressure vessel temperature. However, the temperature measured by these methods is not equal to the true temperature inside the pressure vessel due to the temperature gradient. To accurately measure this temperature, place a platinum resistance thermometer inside the pressure vessel. However, in this case, the resistance thermometer must be sealed to prevent liquid
