加拿大不列颠哥伦比亚大学的研究人员研制成功了液氢脉泽原子钟。它比目前最准确的氢脉译原子钟要准确10倍,在理论上准确1000倍,三亿年只有1秒钟的误差。这种高精度的原子钟是在0.5K 的低温下工作的。由于低温而使电气噪音大幅度下降,热膨胀效应也非常小。在通常的氢脉泽中,为了防止氢原子吸附在真空管的内壁上,涂上聚四氟乙烯薄膜,但它在低温下没有效果。然而,在液氢脉泽中,液氢簿膜也能起聚四氟乙烯的
Researchers at the University of British Columbia in Canada successfully developed the liquid hydrogen maser atomic clock. It is 10 times more accurate than the most accurate hydrogen atomic clock, 1000 times theoretically correct, and only has a one-second error of 300 million years. This high-precision atomic clock is working at a low temperature of 0.5K. As a result of low temperature and electrical noise dropped significantly, thermal expansion effect is very small. In a usual hydrogen gas maze, a polytetrafluoroethylene film is coated to prevent hydrogen atoms from being adsorbed on the inner wall of the vacuum tube, but it has no effect at low temperatures. However, in the liquid hydrogen maze, liquid hydrogen membrane can also play polytetrafluoroethylene
