The plastic go down the hopper smoothly and is gripped by the thread of the screw. It is forced to go toward the direction of the gear end along with the rotation of the screw. A mechanical transferring process is formed. During the running of the plastic from the feed port to gear end, a high pressure is formed in the process of plastic curing due to the gradual decreasing of the thread depth and the resistance of filter gauze, splitter plate and gear end. The high pressure helps to press the raw material and improve its heat conductivity performance and the quick melting of the plastic, at the same time, the gradual increasing pressure can help the gas which is among material particles exhausted from the air holes.

在压力升高的同时，塑料一方面被外部加热，另一方面塑料本身在压缩、剪切、搅拌的运动过程中，由于内磨擦力也产生了大量的热，在外力和内力的联合作用下，塑料温度逐渐增高，其物理状态也经历了玻璃态--高弹态--粘流态的变化，一般地说来，在加料段中主要是玻璃态，在螺杆螺纹逐渐减少的中间部分压缩段中，物料主要处于高弹状态，同时也逐渐的熔融，而物料到压缩段后部和化段作用处于粘流态了，这时我们称塑料已完全塑化了，由螺杆推力作用将塑化的塑料定压定量的从机头中挤出。

Adverse weather conditions in some major food-producing regions are also contributing to the pressure.

此外，部分主要食品生产国的不利天气状况也助长了食品价格压力。

Note that the pressure gauge line inlet apparently got partially blocked by exhaust residue.

请注意，该压力计线入口，显然有部分堵塞排气残留。

The abnormal high-pressure of great area appeared in Shihezi Formation of Upper Paleozoic during secondary gas migration period, which became pressure-sealing to prevent gas from its upward-cross migration and dispersion, while in local area the abnormal high-pressure of Upper Paleozoic strata provided dynamic to its downward-cross migration.

二次运移期间，在上古生界石盒子组出现较大面积的异常高压，形成了阻止天然气向上穿层运移扩散的压力封闭；而部分地区上古生界内部的异常高压为上古天然气向下穿层运移进入奥陶系提供了动力。

In the first part, an infrasonic pressure chamber system was established.

第一部分为次声压力仓系统的建立及性能检测。

On the base of above models and theories, three new kinds of bits, i.e. extended nozzle roller bit, self\|resonating water jet bit and combined jet and mechanical rock\|cutting bit, are developed.

当时 ，部分学者片面认为水射流的压力越高越好，日本研究出 170 0MPa的增压器，前苏联和美国研究出 56 0 0MPa的脉冲射流发生器。

First, we adopt MEMS technology to fabricate micro venturis with different widths of 150 and 200 um respectively and utilize FLUENT software to analyze the flow fields. Air was set as the working fluid and the air mass flow rate of inlet is changed to obtain the pressure drop between inlet and outlet. When a flow passes through the throat, the backflow results in the symmetric separations occur and grow with the increase of mass flow rate.

在微文氏管的研究部分，首先利用微机电制程技术制造出两种不同尺寸的微文氏管，宽度分别为150及200微米，开口角度各为45°，总长则为10 mm，再以空气作为工作流体，利用不同质量流率来量测微文氏管进出口的压力差并配合FLUENT软体分析观察其流场分布的情况。

Pressurized fluid flows through the center of the shock absorber through a poppet valve.

压力流体通过一个提升阀流入该减震器的中心部分。

Tool parts for high impact such as hammer cheeks, planishing and gripper cheeks. Paper cutting knives, tobacco cutting knives, roll segments.

承受高压力的工具部分，比如锤面、精轧夹面、制动器的制动面、裁纸刀、切烟刀、碾压齿轮。
