压力的

This study shows investigation and analysis of the professional stress among primary school teachers.

本文首先采用量的研究方法，对广州市天河区5所小学教师的职业压力强度作了问卷调查；然后，再采用质的研究方法，根据研究主旨的要求，从上述学校中选择部分教师进行访谈和观察，并结合个案研究，全面深入地展现了天河区小学教师职业压力的强度、来源及其个体表现等情况；最后，本文探讨了缓解天河区小学教师职业压力的一些具体管理策略。

The experiment acquired pressure distribution and circulating rate under three fluidizing velocity (3.5m/s、4.5m/s、5.5m/s) and different media load. An experimental equation was acquired between circulating rate and the distribution of the pressure. And the relation between the circulating rate and the opening rate of the valve connecting the returner and the EHE was carefully discussed as well as the relation between the pressure of the EHE and the flow rate of the fluidizing air.

得到三种流化风速下（3.5m/s、4.5m/s、5.5m/s）不同装料量所对应的主床床体压力分布和物料循环量，得到循环量与压力的分布和流化风速的本实验台上的经验公式，并通过测量返料器通向外置换热器机械阀开度和返料量的关系，得到旋风分离器中下落物料进入换热器和直接进入主床的比例关系，同时测得换热器中压力和送风量的关系。

The results show that the amorphous PLGA fiber with porous structure (0.1-1.0 μm) is obtained by diluted solvent spinning method and the mechanical properties is affected by pressure and temperature. Bending strength and shearing strength of the samples increase firstly and then decrease with the increase of molding temperature and pressure. While the molding temperature is 160℃and the pressure is 105MPa, the PLGA materials possess optimal mechanical properties, bending strength, shearing strength and bending modulus 187.3 MPa, 100.0 MPa and 2.5 GPa, respectively. The mild temperature molding PLGA materials are desired to play a grate role in non-bearing internal fixation devices.

研究结果表明：非晶多孔结构的PLGA纤维可通过溶液沉析纺丝的方法获得，其孔径为0.1~1.0μm；压制压力和压制温度对材料的力学性能影响较大，材料的抗弯强度、剪切强度和抗弯模量均随着温度和压力的增大而先增大后降低；在压制压力为105MPa，压制温度为160℃时，试样的力学性能比较理想，此时，其抗弯强度可达到187.3MPa，剪切强度达到100.1MPa，抗弯模量达到2.5GPa，可望作为非承重部位骨折愈合内固定材料。

Tensiometer there are two kinds of mechanical and electronic measurement unit of tension, with Newton/cm.

压力仪有板滞式和电子式两栽，丈量压力的单元用牛顿／厘米表现。

Working Principle Transmitter is composed of sensor and electronic element circuit, pressure of measured medium directly applies on sensor s ceramic diaphragm, force diaphragm to displace tinily in proportion to pressure of medium, under normal working condition, diaphragm displace no more than 0.025mm, electronic circuit detects this displacement, and convert it into standard industrial measuring signal i.e.

工作原理变送器由传感器与电子元件线路组成，被测介质的压力直接作用于传感器的陶瓷膜片上，使膜片产生与介质压力成正比的微小位移，正常工作状态下，膜片最大位移不大于0.025mm，电子线路检测这一位移量后，即把这一位移量转换成对应于这一压力的标准工业测量信号（4~20）mA。超压时膜片直接贴到坚固的陶瓷基体上，由于膜片与基体的间隙只有0.1mm，过载时膜片的最大位移只能是0.1mm，所以从结构上保证了膜片不会产生过大变形。

Teachers with moderate and severe pressure is up to the total number of 82.45 percent.

61%。具有中度职业压力和严重职业压力的教师总数达到82。

Water supply pressure should not exceed 80% of the working pressure of the water heater.

供水压力不能超过热水器工作压力的80%。

We are not by nature well-endowed to handle chronic stress, so managing it is a losing battle.

我们天生就不是处理长期压力的好手，所以试图管理压力注定是场败仗。

Compared with the "Specifications for Marine Biological Survey of China" and "Specifications for Marine Monitoring of China", this guidelines has three significant features:①It covers not only the natural parameters (including marine biological and environmental parameters) but also anthropogenetic parameters which indicate the highly extensive exploitation status in the coastal waters;②The framework of marine ecological assessment consists of 3 keystones: i.

与《海洋调查规范海洋生物调查》和《海洋监侧规范》比较，该指南具有3个显著特点：①调查要素不仅包括海洋生物和海洋环境等自然要素，还包括人为活动要素，充分考虑我国近海生态系统的高强度开发利用的特点；②从生态系统的结构、功能和压力3个方面建立起海洋生态系统健康评价的核心框架体系；③提出生态压力的量化指标，定量评估人类活动对生态系统的压力。

A range of the autofrettage pressure permitted is presented and the best autofrettage pressure is decided according to the DOT CFFC.

最后，根据DOT CFFC标准确定出了预紧压力的范围，根据应力幅和平均应力确定出了最佳预紧压力。

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。
