The blood pressure of.1 of pathology physiology mechanism that SAS causes CVD breathes time-out to be able to bring about airframe in elevatory Morpheus anoxic, sympathetic is excessive and excited, element of serous catechu phenolic amine, kidney and hemal endodermis element are elevatory, bring about hemal easy of hemal convulsion; to shrink the function is disorder, can make blood-vessel flowing flesh happening reframes and fleshy, systemic blood-vessel obstruction adds element of the kidney when; is chronic and anoxic, system of hemal and nervous element is activationed, bring about blood pressure to lift. Obstruction of way of energy of life of patient of OSAS of disease of blood of 1.2 low oxygen increases, cause air current to interrupt, breath pauses, at the same time airframe gets used to low oxygen environment gradually, breathing centre drops to low oxygen and sensitivity of disease of blood of tall carbonic acid, breath suspends a frequency increasing, farther aggravating airframe is anoxic. 1.3 heads are self-adjusting the function drops normal person changes quickly in systematic circulation blood pressure when, the head can be passed adjust independently functional generation protects effect, make change of cerebral blood flow not big.

SAS诱发CVD的病理生理机制。1血压升高睡眠中呼吸暂停可导致机体缺氧，交感神经过度兴奋，血浆儿茶酚胺、肾素以及血管内皮素升高，导致血管痉挛；血管舒缩功能紊乱，可使血管平滑肌发生重构和肥厚，全身血管阻力增加；慢性缺氧时肾素—血管紧张素系统被激活，导致血压升高。1.2低氧血症OSAS患者气道阻力增加，造成气流中断、呼吸暂停，同时机体逐渐适应低氧环境，呼吸中枢对低氧和高碳酸血症敏感性下降，呼吸暂停次数增加，进一步加重机体缺氧。1.3脑自动调节功能下降正常人在体循环血压快速变化时，脑可通过自主调节功能产生保护效应，使脑血流量变化不大。

Especially, the measure of some causticity liquid is very difficult using the old flow meter.

特别是工业中对一些具有腐蚀性的液体的流量测量，普通的流量计根本无法测量。

The relationship between the Q value of ultrasonic resonant cavity and attenuation coefficient is educed for the first time,which supplies theoretic support to get the coefficient accurately by interferometry,and a practical method is introduced.

通过测量介质的声学特征量得到介质的某些理化常数的技术称为声探测技术。如测量液体的密度、浓度、粘度、流量、液位以及固体的致密度、晶粒度或球化率、弹性、硬度、厚度

At 87 psi they achieve a flow rate of 2 5 and 9 CFM.

他们在87防扩散实现2，5流量和9立方英尺。

The air flow: 15,02~35,48 CFM cu. feet/min.

空气流量：15，02~35，48莫桑比克立方米英尺/分钟

In this case the maximum noiselevel composes 34 dB, and the air flow is51,3 CFM.

在这种情况下，最高噪音水平composes 34 db ，并与空气流量是51，3 cfm的。

In a typical general office building, the difference in fan cfm between a constant volume system and the average flow in a VAV system is typically 30%- 40%.

在一个典型的普通办公楼，差额采用CFM风扇之间的恒容体系和平均流量的变风量空调系统通常是30 ％- 40 ％。

The load through the mouth feedback to change the variable distribution of the oil pump plate angle in order to change the pump displacement.

采用恒功率变量泵控制方式，通过负载反馈使泵的压力、流量自动调节到最佳大小，使控制性能和节能效果大为提高。

Traffic over the D channel employs the Link Access Procedure on the D Channel protocol.

在D通道上的流量须应用在D通道上的链路存取程序之协定。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
