Aiming at the fracture in operation of damageable pump shaft used on locomotive, macroscopic and microscopic analysis of the pattern of fractured cross section in pump shaft is conducted and it is recognized that the fracture is typically caused by combined action of bending and torsion fatigue.

针对机车用水泵轴在使用中容易发生断裂的问题，对水泵轴断口的宏观和细观形貌进行了分析，认为断口为典型的弯扭复合疲劳断口。通过检测水泵轴上装配的齿轮，发现由于齿轮的加工误差过大，在轴的退刀槽根部造成了较大的附加拉应力，最终导致轴的断裂。因此及时消除齿轮的加工误差，同时提高安装精度，是防止此类断裂发生的关键

The big size anvil used wax as plasticizer at dewaxing. The main dewax stage from 270℃ to 400℃. Have gas release summit between 400℃ and 750℃. Setting up rational process date at dewax stage can prevent cemented carbide crack. But the crack will appear and impair the quality of products when the microcrack flaw inner compact.

石蜡工艺大制品顶锤在脱蜡阶段，270℃-400℃为成型剂石蜡的主要脱除阶段，400℃-750℃时有气体释放高峰状态，在脱蜡预烧阶段设置合理工艺参数可以防止合金裂纹，但压坯本身若存在微裂纹缺陷，必然会显露出来影响产品质量。

During the process of the fore mentioned analyses, some tentative works as follows were done.(1)On the basis of the fundamental of spatial analytic geometry, the basic method for displaceable block searching was put forward and the relevant program was written. With this program one can easily search out all the displaceable blocks and omitting of blocks, which is very common in searching blocks manually, can be avoided.(2)The coefficient of stability of blocks with failure mode II-2(that is, sliding on a single sliding surface, but confined by near intersecting line )was deduced.(3)The multi-cavern effect of Laxiwa underground caverns was studied on the assumption that all of the caverns were full face tunneled at the same time.(4)The stability classification scheme of rock mass surrounding large scale underground caverns was established. In addition to inherit the merits of the method of engineering geological

在完成上述工作的过程中，本论文主要在以下几个方面进行了一些探索：①基于空间解析几何原理，提出了块体搜索的基本思路并编制出相应的程序，基本实现了块体搜索的自动化，既大大缩短了块体搜索时间，又能防止因人工搜索引起的遗漏；②推导出Ⅱ-2型(单滑面滑动，但受侧限面约束)块体的稳定性系数计算公式；③以数值模拟方法论证了拉西瓦地下厂房洞室群全断面一次开挖时群洞效应的具体特点；④以岩体质量、开挖效应、群洞效应和次生灾害效应为评价指标，建立了&大型地下洞室群围岩稳定性分类&方案；该方案既继承了水电行业规范&围岩工程地质分类&法的优点，又综合考虑了大型地下洞室群的工程特点。

Information technology is believed to produce considerable influence on all of the five basic elements of an enterprise' s internal control system:(1 )"Horizontalization" of the enterprise' s organizational structure is possible, the control group becomes the best form of the enterprise' s autonomous control and the enterprise's control limit is expanded;(2) The range of risk control is enlarged, which increases the risk of the enterprise staff's involvement in decision-making and meanwhile provides an instrument for risk control;(3) The difficulty and complexity of internal control increases;(4) The enterprise information system gets vulnerable to illegal intervention;(5)The enterprise' s internal control takes the form of man-machine model.

企业内部控制是企业为保护其资产安全，保证信息的完整和正确，促进经营管理政策得以有效实施，提高经营效率，控制经营风险，防止舞弊行为发生，并进而实现企业目标的一项重要的管理制度与方法，它由控制环境、风险评价、控制活动、信息与沟通、监控等相互关联的五个基本要素构成。在信息技术环境下，企业内部控制系统的五个要素构成的框架体系并未发生实质性的改变，但企业信息环境的急剧变化，给企业内部控制带来了新的问题与挑战，影响并改变着企业内部控制要素的具体内容与表现特征。
