Based on the safe operation of pilot valve piston pressure relief valve (PilotOperatedPressureReliefValves) series.

国内一般称之为先导式安全阀，如图6所示，先导式安全阀由主阀和导阀组成，导阀操作主阀的开启和关闭。

The model of a hydraulic system composed of fluid resistance, fluid capacitance and on/off valve is analyzed. Dynamic model considering fluid resistance and fluid capacitance are set up for on/off valve. Bloc diagram of simulation modules of the hydraulic system is worked out with Matlab/Simulink. The system is simulated through different parameter settings. Influences of fluid resistance and fluid capacitance on flow characteristics of on/off valve are qualitatively analyzed.

对液阻、液容和关阀组成的液压系统进行模型分析，建立了考虑液阻、液容的开关阀动态模型，并利用Matlab/Simulink建立了液压系统仿真模块图，通过设置不同参数对开关阀液压系统进行仿真，定性地分析了液阻、液容对开关阀流量特性的影响。

For example, Figure 1-8 shows two Model 7012 4×10 cards connected to form an 8×10 two-pole matrix.

例如，图1-8中采用两块7012型4×10卡组成了一个8×10的双刀矩阵开关。

Key words:Siemens S7-300 PLC,PID,temperature pickup, solid state relay

加热炉温度控制系统基本构成如图1.1所示，它由PLC主控系统、固态继电器、加热炉、温度传感器等4个部分组成。

We could put the stone surface under the sunlight lamp or sun, granite and marble , stone products observe its reflecting surface, then could see clearly these kind of concave and strip, if it is because of the mineral, we could ignore it, but if it is because of the bad polish, then had better to avoid to purchase this kind of stone.

我们把加工好的石材表面对着太阳光或日光灯，观察反光面就可以清楚发现如图所示的各种凹坑和条痕，对于那些无规则的细小凹坑可能是由石材组成矿物的一些自身缺陷造成的，可以不去考虑，而如果在石材的表面发现一些有规律的条痕，则是由于加工质量较差造成的，选购时应尽量避免这样的石材。

A line strip is a primitive that is composed of connected line segments.

线条带是有连接的线段组成的图元。

The image shows a young sun-like star encircled by its planet-forming disk of gas and dust.

图中，由气体、尘埃等组成的原始行星盘围绕着一颗与太阳质量类似的早期恒星，而硅酸盐构成了大部分尘埃。

Through the course, students are expected to learn the basic theories of house construction; to master the general construction making of buildings and the drawing methods of detailed construction pictures; to be able to read shop drawing of general industrial and civil buildings and draw building's shop drawing according to design intentions; to know the construction design principles for general buildings; to have basic knowledge of construction design and to be able to correctly understand design intentions.

建 筑构造部分介绍建筑的组成、各组成部分的构造原理和构造方法，建筑设计部分介绍一般建筑的设计原则和设计方法，包括总平面布置、平面设计、剖面设计、立面体型及细部处理等方面的问题。通过这门课程的学习，使学生掌握房屋构造的基本理论；初步掌握建筑的一般构造做法和构造详图的绘制方法，能识读一般工业与民用建筑施工图，并能按照设计意图绘制建筑施工图；了解一般房屋建筑设计原理，具有建筑设计的基本知识，正确理解设计意图。

"Kids with mild tics are at a higher risk for developing future school problems. This is a way of identifying children ahead of time so they can be monitored - a clue to how the child's brain is organized," says lead study author Dr. Roger Kurlan, director of the Tourette's Syndrome Clinic and the Cognitive and Behavioral Neurology Clinic at the University of Rochester in New York.

文本研究第一作者、纽约罗切斯特大学图雷特氏综合症诊所和认知及行为神经学诊所的所长Roger Kurlan博士说：&有轻微抽搐的孩子将来发展成学习问题的危险很高，这样可以提前诊断这些孩子，及早监测他们，这也提供了一个帮助了解孩子的脑组成的线索。&

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
