查询词典 partial pressure

The results of calibration of 4He in desorption system show that the correlation coefficient is more than 0.99 and the contribution of memory effect can be ignored. The contribution of ionized atom T(superscript +) for partial pressure of m/e=3 is very little and is determined according to I+≈0.01I(subscript T2)+, so the measurement of 3He can be done without interference of T(superscript +). The relationship between gases release rate and annealing temperature can be obtained after the data are smoothed and differentiated.

研究结果表明：四极质谱计标定解吸系统内4He的分压＜350 Pa时，其相关系数R＞0.99，且记忆效应的贡献极弱；离子态氚T对m/e=3组分分压的贡献可按I+≈0.01I(下标 T2)+确定，不干扰3He的测定；将气体解吸所得的积分数据经平滑并微分处理后可准确得到气体释放速率与退火温度的关系，即热解吸谱。

The temperature of the zeolite structure damage is at 1169℃.According to the sorption isotherms, hexane and methanol are adsorbed in the ten-membered ring channel. Methanol molecules can enter the small cage through the eight- membered ring window at high partial pressure. The adsorption of water correlates to Si-OH defect and concentration of cations in the zeolites.

吸附现象表明，正己烷和甲醇都被吸附于FER沸石的十元环主孔道中，分压较高时，甲醇可通过八元环进入小笼，而水的吸附性质则主要与各样品的Si-OH缺陷及骨架中的阳离子含量有关。

It was found that the partial pressure of Hg could influence As diffusion and Hg vacancies in epilayers assisted fast diffusion of As. The As diffusion at a lower temperature of 240℃/24～48 hrs was negligibly slow.

研究表明在低温段的240℃/24～48小时的退火中As的扩散非常有限，对样品中As的浓度分布影响不大，而在高温段380℃/16小时和440℃/30分钟退火中，As扩散较为明显，能使原来的PN突变结变缓。
