第一步，在选型时多比较各供应商的选型方案，在考虑性价比的前提下尽量选用效率高的方案；第二步，派驻一定的专业人员驻厂监制，对影响水泵效率的关键零部件如叶轮、泵体、泵盖、导流器等的制造质量进行监制，尤其对叶轮的翼形、出水角、叶片的分度、流道的形状、光洁度等质量进行控制，使交付的产品是在当前的生产条件下的高效率的产品；第三步，在生产现场的安装调试过程中，要保证泵的基础牢靠，与驱动机对中良好，前后阀门开关灵活，管道布置设计合理，现场控制安全可行，各运行监控仪表齐全准确，保证泵的运行过程能够进行实时监控；第四步，是在水泵的长期运行中要注意对设备的点检，发现异常情况即时反映汇报，在正常的小修、大修周期中，应对各易损件进行检查更换，保证泵的长期高效安全的运行。

We can approach the modernity of the economic legal norms by manifesting the basic unit of behavior, legal rule and legal standard, and the system of Economic Law, realize the modernity of the function of Economic Law by revealing it is the guarantee that could overcome the difficult position of modernity and propel the project of modernization, detect the modernity of operation of Economic Law by inspecting its legislature, enforcement and judicature. Lastly, the author assumes that the problem of the legitimacy of Economic Law should be resolved by realizing substantive legitimacy of Economic Law in its operation.

书中指出，经济法本质的现代性体现为经济法是实质合理性与形式合理性相统一的法；经济法律规范结构的现代性体现为微观层面的"原子"行为单位的现代性、中观层面的"规则"和"标准"的现代性以及宏观层面的经济法律体系的现代性；经济法功能的现代性体现为经济法是克服现代性困境的制度保障或推进现代化事业的制度保障；经济法运行的现代性体现在作为求解经济社会问题之"新法"的经济立法、作为一种现代社会的"新的管理方式"的经济执法和以"目的指向"裁判方式为特征的经济司法上；而经济法在经济立法、经济执法和经济司法中出现的合法性问题其实就是经济法运行中的现代性问题，该问题的解决得益于经济法运行中实质合法性的实现。

The bridge type derrick big car will appear to chew track phenomenon in the movement, slight of chew a track will result in a good luck and orbit of the on the side have obvious of wear away trace, severity chew a track will result in a good luck and orbit of the on the side metals be peeling off or the round's good luck outwardly transform and even jump the track to result in graveness Human body dead and injured and equipments trouble.

桥式起重机大车在运行中会出现啃轨现象，轻微的啃轨会造成轮缘及轨道的侧面有明显的磨损痕迹，严重啃轨会造成轮缘和轨道的侧面金属剥落或轮缘向外变形，甚至脱轨造成重大人身伤亡和设备事故。

Dedicated underwater cases for compact digital cameras generally run at least half the purchase price of the camera, so the 720 SW's $400.00 price tag is a real bargain for snorkelers, sailboarders, boaters, swimmers, water skiers, seashore lovers, and beachcombers.

专用的水下情况下，数码相机，一般在运行中至少有一半价款的摄像头，使720西南的四百点○○美元的价格是一个真正的讨价还价的snorkelers ， sailboarders ，船民，游泳，滑水，海滨情侣，并

But due to influence of all kinds of factors, power cable may go wrong.

但在运行中由于各种因素的影响，电力电缆也会发生故障。

In the operation, many factors have influences on vacuum degree of condenser, among which the main factors are: inlet temperature of cooling water, flow rate of cooling water, tube bundle surface cleanness of condenser and vacuum system tightness, etc.

在运行中，影响凝汽器真空度的因数很多，其中主要有：冷却水进水温度、冷却水的流量、凝汽器管束表面的清洁状况，以及真空系统的严密性等。

Since the turbine-driven feedwater pump failed to regulate directly the drum level of single boiler and problems like pressure overrun of main feedwater pipe existed, DCS was utilized to solve the problems for its features of shared information, powerful configuration functions and easy modification.

在对国电成都热电厂嘉陵2×142MW机组两炉一机单元给水系统控制方式进行分析的基础上，针对运行中出现的汽动给水泵不能直接调节单台锅炉汽包水位及给水母管压力超限等问题，利用分散控制系统信息共享、组态功能强大、修改方便的特点，在不增加硬件设备的情况下，通过软件组态增加了汽动给水泵调节单台锅炉汽包水位调节回路和给水母管超压及欠压保护回路，实现了机组在一炉一机单元运行和两炉一机母管运行2种运行方式下给水自动的合理控制，并解决了给水母管的压力保护问题，提高了机组运行的安全可靠性。
