This paper focuses on a discussion of following issues through a combined of theoretical analysis and numerical calculation , and of theory - oriented , engineering analogy , experience and quantitative test . the stability analysis of slopes of deep foundation pit ; checking caculation of tensile breaking limiting condition of soil - nailing , grouting nail sheath anchored limit condition , rising of bottom of foundation pit and piping . measures are proposed for applying this method to slit stratification in disadvantage geologic 本文介绍了土钉支护技术的发展及作用机理，并结合工程实例，采用以理论为基础，重点研究探讨了土钉支护在深基坑边坡稳定分析、土钉抗拉断裂极限状态验算、整体稳定性验算、注浆钉包裹体锚固极限状态验算、基坑底隆起验算、抗管涌验算等方面设计计算方法，并提出了在其它不利地质环境中采用土钉支护应采取相应的措施。
With the capability of electrical system increasing , the former device can not yet satisfy what the dispatching automation asks for the remote terminal unit on reliability , rapidity and accuracy . the new measurement and control device , which undertakes the task of measurement and control , is one kernel part in the bay of substation automation system 为了保证供电的质量和电力系统的可靠性和经济性，系统的调度中心必须及时而准确地掌握整个系统的运行情况，随时进行分析，作出正确的判断和决策，必要时采取相应的措施，及时处理事故和异常情况，以保证电力系统安全、经济、可靠地运行。
These problems include : environmental pollutions due to poor quality of water and huge amount of stone mill dust , competitive power problems due to innovations and market orientations and the construction of mining areas , etc . measures corresponding to aforementioned problems were taken by relevant government agencies and companies to regulate the situations so as to create a well - ordered environment for future developments 包括：环境污染问题(水质和石粉尘等) ；竞争力问题(创新和市场等) ；矿山建设问题等。面对上述问题相关部门和企业应该采取相应的措施加以整治，创造有利于发展的良好内外部环境，阐述了如何开发石文化旅游资源。
Intrusion detection techniques can help us to detect attacks against computer system by monitoring the behavior of users , networks , and computer systems . by monitoring and analyzing , the anomalous and illegal activities been taken can be discovered , which include attack using security vulnerabilities by legitimate users or unauthorized access 其主要通过监控网络与系统的状态、用户行为以及系统的使用情况，来检测系统用户的越权使用以及入侵者利用安全缺陷对系统进行入侵的企图，并对入侵采取相应的措施。
The prediction of customer churn in telecommunication is a bit hot . the analysis of the prediction of customer churn is to analyse the losed customer ’ s history data to find out their characters for leaving which help the telecommunication compay to early adopt measure , then reduce customer churning . it has important meaning for the telecommunication compay 客户流失分析是通过对以往流失客户的历史数据进行分析,找出可能离网用户的特征,及时采取相应的措施,减少客户流失的发生。这对企业降低运营成本,提高经营业绩有着极为重要的意义。
The bridges are pivotal stronghold of the whole road . it becomes more and more popluar that some existing bridges betray multifarious structure damage and the limitations below the anticipative functions inevitably by reason of structure aging or vehicle load increasing or adverse environment or maintenance deficiency . lt results in not only the local bottleneck of the line and hidden trouble to the passing vehicle if the defective bridges are not duly maintained and reinforced . as a result , the bridge evaluation is specially important to the maintenance and strengthening . futhermore , we can not demolish and rebuild only but adop corresponding measures according ad temporal condition when the bridges are deemed to have defectiveness . so it accords with the situation of a country that the reinforcement and other upgrade measures aim at the bridge attention 由于结构自然老化、车辆荷载增加、不利环境影响以及养护维修欠缺，一部分桥梁不可避免地要暴露出各种结构损伤和既有桥梁不满足规定功能要求的问题越来越普遍。如果这些技术状况不佳的桥梁得不到及时的维修和加固，不仅会造成整条线路的局部瓶颈，而且还会对通行的车辆造成极大的隐患。因此，桥梁评估作为桥梁维修和加固的依据就显得尤为重要；此外出现了技术状况不佳的桥梁应根据实际情况采取相应的措施，而不能仅仅采取拆除重建的方法，因此加固和其他升级方法是目前比较符合中国国情的桥梁改造措施。
In section four the thesis in details analyzes the reason of the " alteration " in curriculum implementation , mainly including three aspects of reason : firstly , the reasons of curriculum itself , that is value orientation formerly - designed curriculum , practicability and elasticity of curriculum plan ; secondly , influence come from the interior of education system , that is curriculum design , the difference between designer and implementor , the hinderance of linking up in the chain of main - body ; thirdly , influence come from external environment , that is traditional view from society , the support and policy which forms a complete set from the government , the regional feature of curriculum implementation and the development and changes of times and etc . in section five the thesis talks in details about how to promote to produce " construction " effect and how to restrain " impediment " effect 第四部分，具体分析课程实施中“异变”出现的原因。主要包括预设课程的价值取向、课程计划的可行性、课程计划的弹性等课程本身的原因；教育系统内部课程规划、设计者与课程实施者的异质性、课程实施过程中主体链沟通障碍也容易引起异变的产生、课程实施者的素质等方面的原因；外部环境社会传统观念的影响、政府部门的配套政策与支持、课程实施的地域特点、时代的发展变化等方面的原因。第五部分，具体探讨在课程实施中如何采取相应的措施促进“异变”的建构效应的产生，抑制其阻碍效应的产生。
In the whole process of an engineering investment project , there must be various kinds of unstable factors that can take the positive or negative effect upon the project , but the final result is come into being by all these unstable factors . in order to ensure the real benefit , it is absolutely necessary that objective and re asonable analysis and evaluation of the risk be made and corresponding measures be taken . there is very important practical significance to improve the economy benefit of construction project investment in our country 在一个工程投资项目的全寿命周期过程中，会出现各种不确定性，每个不确定性都会对项目发生影响，但最后的影响结果是由这些不确定性共同作用而产生的，为了确保建设项目的实际收益能力，事先对其风险进行客观、合理的分析与评价，并采取相应的措施是完全必要的，这对于改善我国建设项目投资的经济效益具有十分重要的现实意义。
