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。

The air here is getting cleaner and cleaner.

The results showed that the peak latency and pattern of SEPs elicited by electrical needling in LI-l1 and MP were similar. The amplitude of SEPs elicited by electrical needling in LI-l1 was higher than that of MP. There was no obvious SEPs generation when MM was electrical needling.

结果显示，电针刺激曲池穴和其邻近桡侧伸腕长肌运动点诱发性脑电波的波形和波峰时间是类似的，只是穴位的诱发性脑电波波幅较大，而电针刺激非穴位点并没有明显的诱发性脑电位。
