Presently there exists no convenient method to determine the baking temperaiure for glass vacuum chamber which uciuall plays an important role in the acement of required vacuum circumstance in high-vacuum system made of glass,In this paper approximate method was represented to calculate the baking temperature of glass surface by the emissivities of appropiate materinl surface,determining the baking temperature difficult to be tested by the relation ship recommanded by the paper and the indication of an ausa...

在高真空系统中，真空室的烘烤温度对获得要求的真空氛围有着重要的影响，对于玻璃制作的真空系统，目前对于该温度的确定缺少一种较为简单易行的方法，本文基于辐射换热分析提出了具有通用性的利用材料表面辐射率来计算玻璃表面烘烤温度的近似方法，将这难以直接测量的温度通过附设热电偶的示值和本文推荐的关系式来确定，于实际情况相比较为吻合。

First, we deduce a formula for vacuum polarization pressure as f ＝ G m M （ r ∕ r ＋ v ∕ c ）∕ r 2 , based on the isotropy of distribution of neutrinos ν0 in the lowest energy state in the physical vacuum, requested by the Pauli exclusion principle. Then, we deduced the metric equation of the general relativity and the equivalence principle according to this formula. Further, we demonstrate that this vacuum polarization pressure is the gravitation in general meaning.

首先从泡利不相容原理要求的在物理真空中最低能态中微子ν0分布的均匀各向同性出发，推导出真空极化压力公式 f ＝ G m M （ r ∕ r ＋ v ∕ c ）∕ r 2 ，然后由此公式推导出广义相对论的度规方程和等效原理，并论证此弱作用力的真空极化压力就是通常意义下的引力。

Saddle shaped AMF can produce a radial expanding force, which has more effective effect on resisting the pinch effect of self-generated azimuthal magnetic field of arc current. This effect of saddle shaped AMF can keep vacuum arc in diffuse mode under much higher current. So the limiting current interruption capacity of vacuum interrupter can be enhanced.

为了进一步提高纵向磁场对真空电弧的控制作用，本文提出在真空灭弧室的触头间引入从触头中心向边缘逐渐增强的非均匀纵向磁场，马鞍形纵向磁场会对真空电弧产生一个径向扩张力，而纵向磁场分布的合理设计可以使这一扩张力进一步抑制真空电弧自生环向磁场对电弧的箍缩作用，从而使真空电弧在更大的电流时仍能保持在扩散态，使真空灭弧室的极限电流开断能力得以提高。
