Discussion on condition testing the degree of ultimate vacuum of ultrahigh vacuum diffuse pump oil;

超高真空扩散泵油极限真空测试条件的探讨

The wake shield facitity(WSF) extreme high vacuum system makes use of the property that its orbiting velocity is several times higher than the ambient atmosphere s thermal velocity,leading to a very high pumping by space,hence a rarefaction region up to extreme high vacuum is produced in the wake rigion of WSF.

轨道分子屏真空系统,是利用分子屏轨道飞行速度远大于轨道环境大气的平均热运动速度,使空间环境对分子屏产生理想的抽速,在尾部形成气体分子的稀化区,达到极高真空。

The third formula is the formula (8,18) about vacuum polarization.

在该书173页上的关于真空极化计算的公式(8,18)。

The one-loop vacuum polarization is calculated for untwisted and twisted scalar fields in a flat space-time with the topology S1×R3.

本文中我们首先计算了在拓扑结构为S~1×R~3的非Minkowski时空中扭曲标量场和非扭曲标量场的真空极化，然后考虑了真空极化对光子传播的影响，我们发现除了光子的极化方向和传播方向都垂直于紧致化方向的情形之外，非扭曲标量场的真空极化使所有其他的光子模式都获得实的拓扑质量从而导致这些光子以亚光速传播；但是，扭曲标量场的真空极化使光子获得虚的拓扑质量以致他们以超光速传播。

It is unveiled that during most of the Mesozoic (200~100 Ma) the paleointensity of the geomagnetic field was very low, only one-third of the mean Cenozoic value, that the geomagnetic field shows no reversals from 124 to 83 Ma, and that the true polar wander (TPW) almost remained a standstill from 170 to 110 Ma.

本文介绍了90年代以来地球物理学在地球磁场方面(地球磁场古强度,地磁场极性反转频率以及真极移)的研究成果,揭示了200～100Ma全球低的地球磁场古强度;124～83Ma低的极性反转频率以及170～110Ma近乎停滞的真极移。

The episodic geomagnetic reversal friquencies and the true polar wander could correlate with lower/upper mantle convection and lithospheric dynamics.
