Matching the composition of the wires between the cryostat and the voltmeter and keeping all dissimilar metal junction pairs at the same temperature allows making very low voltage measurements with good accuracy.

适当的选配低温容器和电压表之间连接导线的材料成分，并且保持所有不同金属材料结点对都处在相同的温度之下，就能够以很好的准确度来进行非常低电压的测量。

Part of the findings shows the composition of pythoncidere is similar to that of the steam-distilled Cryptomeria japonica essential oil, based upon which an experiment about the Cryptomeria japonica essential oil's effect on animals is conducted. This leads to a further finding that the major element of terpene "limonene"is quite effective to central nervous system, and it can be hypnotic, anxiolytic and analgesic.
