机械压力的

Vibration processing/molding has been recently developed, in which polymer melt essentially flows or deforms under periodic stress in direct/superposed mechanical oscillation or ultrasonic vibration shear/pressure so that the flow field and some physical processes are varied.

近年来出现了振动加工成型，其实质是在机械振动、超声波的直接作用或叠加在剪切、压力流上，使聚合物熔体在周期性变化的应力下流动和变形，从而改变流场类型、强化流场强度和一些物化过程。振动会影响材料的粘度和松弛行为，所以也会影响分子扩散和剪切速率敏感的共混等过程。

The machinery design in engineering of external pressed vessels is based on the mathematical model of critical press and metallic material's stress-straincharacteristic curves together with the nomography.

对于外压容器的机械设计，在工程上是以临界压力P_(cr的数学模型和金属材料的应力-应变特征曲线结合的图算法完成。

This item is a new type structure direct-acting overflow valve, which adopts dynamic pressure feedback principle. That is it adds a feedback cavity on common direct-acting overflow valve's core. When there is overfall on valve port, the hydraulic force of valve port will balance with feedback cavity's hydraulic force and spring force, so it can decrease spring's stiffness, just like adding a hydraulic spring, which works together with mechanical spring, so as to minish valve port pressure range.

本项目是一种新型结构的直动式溢流阀，采用动压反馈原理，在普通直动式溢流阀阀芯上增加一反馈腔，当阀口溢流时，阀口的液压力与反馈腔液压力和弹簧力相平衡，从而可以减小弹簧的刚度，等于增设了一根液压弹簧，使其和机械弹簧一起工作，以达到减小阀口压力变化范围的目的。

Most of the substances in the deposit were the nonsticky calcium carbonate and fines that could adhere to the sticky contaminants and deposit together, resulting in a great deal of the deposit.

对福建南平纸厂网前压力筛处的胶粘物进行分离和分析发现，以聚醋酸乙烯酯和聚丙烯酸酯为代表的人工合成聚合物以及机械浆中的木材树脂是产生胶粘物的根本来源，但它们在胶粘物沉积中的含量只有5%左右。

A turbocharger is a dynamic compressor, in which air or gas is compressed by the mechanical action of impellers, vaned rotors which are spun using the kinetic movement of air, imparting velocity and pressure to the flowing medium.

蒸气增压器是一台动态压缩机，在哪空气或气体由叶轮的机械行动压缩，使用空气的运动运动转动的vaned电动子，给予速度和压力到流动的媒介。

WANG Zhi-yi, CHEN S, YANG C HSchool of Civil Engineering and Architecture, Zhejiang Sci-Tech University, Hangzhou 310018, ChinaAbstract The cross defrosting cycle was presented in which one air side heat exchanger defrosts by switching over the corresponding four-way valve and the others operate normally.

摘 要：采用四通换向阀换向逆循环除霜，风冷热泵机组系统压力波动剧烈而产生比较大的机械冲击，频繁启动压缩机，影响室内的舒适性与压缩机的寿命，针对逆循环除霜的缺陷，提出了交叉除霜循环的原理和过程。

Besides chemical factors, mechanical effect also plays a certain role in controlling calcification since the stability of calcium carbonate crystal is dependent on pressure.

影响转换除了化学因素外，机械力学也很有关系，因为碳酸钙的稳定度与压力有关。贝类的碳酸钙结晶只产生在开口处，壳会随身体成长，有个有趣的力学机制在控制晶相的转换。

Article 16 Entities maintaining boilers, pressure vessels, elevators, cranes, passenger cableways and large entertainment facilities shall have the professional technicians and technical workers, as well as the necessary testing means, fit in with maintenance of special equipment, and may undertake the corresponding maintenance activities only after they are licensed by the departments of safety supervision of the provinces, autonomous regions and municipalities directly under the Central Government.

第十六条锅炉、压力容器、电梯、起重机械、客运索道、大型游乐设施的维修单位，应当有与特种设备维修相适应的专业技术人员和技术工人以及必要的检测手段，并经省、自治区、直辖市特种设备安全监督管理部门许可，方可从事相应的维修活动。

A new processing technology is adopted for vacuum pressure impregnation of the OH coil. The coil after vacuum pressure impregnation has the same electrical and mechanical properties.

线圈的真空压力浸渍工艺采取一种新的技术，处理后的线圈有同样的机械强度和绝缘性能。

Therefore, you must release the take the wheel and loosen its teeth in its teeth on the shaft by time cam control rocker, but equipped page machine in its wheel is compact, inconvenient demolition, and pick out the teeth and inspection of pressure on the relative position of the key is to detect many parts of the machinery in a manner worthy, opening the restore time, the earliest possible time to 2300 hours, easily affecting production.

因此必须松开叼纸轮的定位，并且松开叼牙轴上受叼牙时间凸轮控制的摆杆，但由于配页机的叼纸轮安装较紧凑，不方便拆卸，且叼牙与检测压力相对位置是检测多帖关键的机械部位，拆开后，还原时间长，最快也要二三个小时，容易影响生产。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
