低压的

We exhale by relaxing the diaphragm –a primarily passive process– into its original dome shape, which decreases the volume of the thoracic cavity and raises the pressure inside the lungs, thereby, pushing the air inside the lungs to a lower pressure outside the lungs.

我们呼气的时候是放松横隔膜—基础是一种被动行动---回复到本来的穹顶型，这样减小胸腔的容积，进步肺部的压力，把肺部的空气压到外部的低压区。

This article describes the present situation of high-pressure and low-pressure flash tank ,gas-liguid separator and purified gas filter.

详细介绍了聚乙二醇二甲醚脱硫脱碳装置中脱硫富液、脱碳富液的高、低压闪蒸槽以及气液分离器和精制气气体过滤器的生产现状，分析了这些设备出现瓶颈的原因，同时提出了相应的扩能改造的基本思路和方法，最后总结了改造的效果。

Extensive research has been conducted to find ways of reducing such porosity; however, it is difficult if not impossible to eliminate completely, and die castings often are lower in strength than low-pressure or gravity-fed permanent mold castings, which are more sound in spite of slower cooling.

大量的研究工作旨在降低这一气孔率，可是实际上要想完全消除是相当困难的，并且压模铸造铸件的强度经常不及低压和重力铸造获得的铸件，尽管后两种方式的冷却速率教慢，但是其可靠性相对较高。

The correctness of logic theory is one of the most important factors in relay protection. This paper validate the testing function of medium and low voltage line protection through the relay protection testing system based on virtual instrument developed by ourselves, so as to make the validation of the correctness of logic theory be independent of the relay protection devices'software and hardware.

保护逻辑原理的正确性是继电保护能可靠动作的重要因素之一，本文采用自行研制的基于虚拟仪器的继电保护测试系统对中低压线路保护测控功能进行了验证，确保保护逻辑原理的正误与微机继电保护装置软硬件无关。

Combined with present situation on overcurrent protection of low voltage electrified wire netting in mine,analysed several reasons on appeared mis-start or refuse-start of overcurrent protection in mine,thus provided some concrete arguments for research workers and users of overcurrent protection .
