This paper studied the fatigue properties of the plain concrete under constant amplitude flexural cyclic loading.

在室内混凝土试件弯曲疲劳试验的基础上，研究了素混凝土受弯试件在等幅重复荷载作用下的弯曲疲劳性能。

The test means of cyclic loading between the set constant of strain seem to be more reasonable for low cycle fatigue with large strain.

对高应变状态下的低周疲劳，采用在设定的应变界限之间重复受力的试验方法似乎更加合理。

In the research of high cycle fatigue of concrete, the test means of cyclic loading between the set constant or various upper limit and low limit of force or stress has been extensively used. But this kind of test means can't be used to study the behavior of concrete low cycle fatigue under large strain.

同时高周疲劳问题研究中使用的在设定的力或应力的上下界限之间重复受力的试验方法已无法用于混凝土高应变低周疲劳性能的试验研究。

It was found that the low cycle fatigue character has close internal relations with the high cycle fatigue character. In the research of high cycle fatigue of concrete, the test means of cyclic loading between the set constant of force or stress has been extensively used. But this kind of test means can't be used in studying the behavior of concrete low cycle fatigue under large strain.

在研究中发现低周疲劳特征与高周疲劳特征有着密切的内在联系，但高周疲劳问题研究中使用的是在设定的力或应力的上下界限之间重复受力的试验方法，这种方法已无法用于混凝土高应变低周疲劳性能的试验研究。

This design takes the diesel cyclinder tank for the clamping and locating device of tank boring and designing the clamping regulations of arts and crafts of tank, we take two cylinders and one face to locate which can limit six free dgrees In order to reduce errors of tank during processing,we take standard and concurrent principle,unify principle,principle with each other for basis and selection of rough basis into order to make the orientation tight enough,it is required to insist in the principle of using the unrepeated coarse beach mark as possible as you can.

本设计以柴油机汽缸箱体为例，对箱体镗孔的夹紧和定位装置进行工艺分析和夹具的设计。在对此箱体的工艺规程采用两销一面对其进行定位以限制其六个自由度。为减少箱体在加工过程中的误差，我们考虑基准的重合原则，统一原则，互为基准原则以及粗基准的选择原则，为使定位稳定夹紧可靠，要求所选用的粗基准尽可能不重复使用原则。

If negative, cytology should be repeated again in four to six months.

如果细胞学阴性，细胞学检查必须4－6个月重复一次。

If repeat cytology is normal, then anothercytology test should be obtained in four to six months.

如果重复细胞学检查是正常的，间隔4－6个月再复行涂片。

First-time fathers shouldn't try to re-create those moments that daughters have with their mothers they should seek out their own special bonding activities, says KidsHealth's D'Arcy Lyness.

儿童健康网的D'Arcy Lyness认为，新爸爸们不要试图重复孩子跟母亲在一起的时间，而是应该建立自己与孩子相处的方式。

And then he repeated how difficult it was to choose, how well everyone had played ... dah, dah, dah.

然后他又重复了一遍选择是何等的难，每位选手的表现何等优秀……等等，等等，等等。

Only long-term mechanism set up in order to protect the production, processing and marketing of coordinated development and avoid dairy farming and dairy processing a two-tier skin, to avoid low-level redundant construction of dairy enterprises, the elimination of the various sectors of产加销conflict of interest.

只有长期的机制，建立以保护生产，加工和销售的协调发展，避免奶牛养殖和乳品加工两层皮，避免低层次的乳品企业，各部门消除重复建设产加销的利益冲突。

And discuss some key point of integrated management system design, include hazard identification and risk assessment and risk control in the occupational health and safety management, the measure of satisfaction target of customer, the flawlessness of law system, the integration of the integrated management system and enterprise standardization system, unify lead institution and work orgnization, integreted internal audit and integrated management review.

同时，论述了一体化管理体系构建中的几个主要问题，包括职业健康安全管理中的危险源辨识、风险评价和风险控制、顾客满意度的科学监测、法律、法规体系的完善、一体化管理体系与企业标准化体系的有机结合、统一的领导机构和工作机构、一体化的内部审核和管理评审。
