实验研究结果表明：所研制的液压变压器能够实现压力调节，调压范围0～1.2；液压变压器的排量由角度决定，不受转速，负载大小的影响；液压变压器输出压力由配流盘控制角度决定，同时受负载的影响。

It means that the city's spatial expansion has not been supported effectively by the transportation system. The polycentric industrial areas and the annularly distributed population do not match spatially.

具体而言，广州市多中心的产业增长和圈层式的人口分布在空间上不匹配，城市未来钟摆式通勤交通的压力将不断加大，而单中心放射状的"双快"交通系统在解决这一问题上是失效的；另外，"双快"系统不利于外围新城市副中心的建设，相反由于与中心城区的快速联系，有可能将大量的人口留在中心城区边缘，给中心城区带来巨大的服务压力。

Pyroxene megacrysts formed under the temperatureof 1200.85-1288.85℃ and the pressure between 0.93 and 1.67GPa, amphibole megacrysts crystallizedunder the pressure of 0.83-0,89GPa, temperature about 1000℃, and anorthoclase maybe at thetemperature of 900℃ around.

To against an afterload of 1.96kPa(200mmH_2O), measure two groups of direct flow and antidromic flow, both begin with the pressure difference of 0mmH_2O, add more 20 mmH_2O every time ,measure three tines at each pressure difference, get the average value at each pressure difference.

测试分为顺向和逆向两组，在克服后负荷压强为1.96kPa(200mmH_2O)情况下，分别从0mmH_2O压力差开始，每隔20mmH_2O递增，测量通过静脉外间接人造瓣膜的生理盐水流量，每个压力差值测量3次，取平均值。

The result indicated that the animal occurred respiratory acidosis when IAP got 15mmHg,and occurred hypotension and ologuresis or anuresis..

结果表明，当腹腔压力达到15mmHg时机体病理生理改变即可出现酸中毒，当腹腔压力达到20mmHg时继而出现低血压、少尿、无尿等症状。

Through transformation of parameters, the meshing design system among Hy-Vo silent chain, sprocket and hob was built up based on the research of the pitch increment and the equivalent apothem increment of the effects on the common normal line length when the Hy-Vo silent chain was wrapped around and located on the sprocket, with the proper meshing conditions of Hy-Vo silent chain and sprocket into consideration. The design method of common normal line length was put forward that can be used when the value of the sprocket pressure angle was equal or unequal to the value of the Hy-Vo chain plate pressure angle.

在分析Hy-Vo齿形链链节围在链轮轮齿上定位时其节距增量和当量边心距增量对链轮公法线长度影响的基础上，根据Hy-Vo齿形链与链轮的正确啮合条件，通过参数变化，建立了Hy-Vo齿形链－链轮－滚刀三者之间的啮合设计体系，提出了既适用于链板齿形角等于链轮压力角情况，也适用于链板齿形角不等于链轮压力角情况的Hy-Vo齿形链链轮公法线长度的计算方法。

The experimental results show that it is necessary to treat the formation with the temporary plugging agent to seal the pay zones for selectively injecting gel into aqueous layers when the effluent water pressure is higher than that of pay zones, or the fractures in oil-bearing zones are much wider than those in the aqueous layer.

在油井水层出水压力高于油层压力或者产油层裂缝大于出水层裂缝情况下，采用笼统注入方式堵水须进行暂堵处理，以封住产油层，使堵剂主剂选择性进入水层。

In the course of numerical calculation, the influence among asperities, the coupling problems of the variation of temperature and pressure on contact surfaces, the variation problems of the maximum temperature, maximum contact pressure, maximum stress were taken account into.

在数值计算过程中，着重考虑了微凸体之间的相互影响，温度变化与接触区域压力变化的耦合问题，最高温度、最大接触压力以及最大等效应力的变化问题。

All children experience peer pressure and give in to it at one time or another.

所有的孩子都会经历来自同伴的压力，并在某些时候屈服于这种压力。

And the atmospheric density on Venus, atmospheric pressure is almost 100 times earth's atmosphere pressure.

而且金星上的大气密度很大，大气压力几乎是地球大气压力的100倍。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
