查询词典 vacuum

While encapsulating RF MEMS switches in low vacuum diminishes the air damping and improves the switch speed and operation voltage, the performances of a switch is incident to being influenced by outside environment.

可见，RF MEMS开关用低真空封装可以减小空气阻尼、改善开关速度和执行电压的同时，开关的性能却容易受外界环境因素的影响。

The specimen were cleaned thoroughly before the measurement, and degased in vacuum to get rid of the air film.

至今科学工作者仍在不断地寻求新的原理和方法以便更精确地测量材料的密度。

Voltage type, it uses a closed rotor, can be widely used in smoke delivery type, delivery type air pressure and vacuum conveying system conveying equipment, it can guarantee the flow pipeline pressure, not leaking, safe delivery and collection node materials, and for this reason called the million air lock, and it can not only pressure, while both common features.

耐压型，它采用封闭型转子，可以广泛用在吸送式，压送式气流输送系统和负压输送设备上，它可以保证输送管内的气流压力，不泄漏，能够安全的输送和收结物料，所以在这方面称为万锁气器，它不但可以耐压，同时兼备普通型功能。

The fresh-keeping effects of Portunus Trituberculatus were investigated. The results showed the efects were better when air components and ratios of MAP were CO2 50% N2 50%. Compared with coating package and MAP, vacuum packing could inhibit the production of melanin in Portunus Trituberculatus gills and legs and prolong storage period effectively at 0-4℃.

结果表明：气调包装气体配比为CO2 50%，N2 50%的保鲜效果较好；但真空包装与气调包装和涂膜包装的保鲜效果相比，0～4℃下，真空包装可有效抑制梭子蟹腮部和足部褐变并延长三疣梭子蟹保鲜期，保鲜效果好于气调包装和涂膜包装。
