LTD. Analysis of invalidation of the two MOOG valves was carried out with the help of advanced apparatus and profound expertise in this area at Fudan University. Our research reveals that poor quality of the valve surface is the root cause for invalidation. A detailed description of the method used in analyzing the invalidation of electro hydraulic servo valve is presented in this article. This research demonstrates that academic institutes can play a significant role to solve engineering problems by leveraging their existing resources.

我们利用复旦大学先进的表征仪器和工具以及积累的大量失效分析案例的丰富经验，对二个失效的MOOG阀的阀体进行解剖分析，判明了失效的真正起因不是液压油质量问题，而是阀滑表面质量存在问题，论文详细论述了我们采用的表征分析方法从宏观上、微观上对电液伺服阀阀的失效行为进行了全面分析的过程，是科研教学机构利用自身资源解决实际问题的一次有效的实践，具有较强的科学意义。

This paper has presented the types and distribution characteristic of the Quaternary glacial deposits on the west side of the Yulong Mountains, which was an important task for the selection and optimization of the Yunnan-Tibet railway line in Northwest Yunnan. Based on lab test of physics and mechanics, the results of engineering properties of moraine/outwash rocks, including the cement composition and their cementation, stability in water, mechanical property, and sound spreading velocity, etc., have been reported, which can not only enrich the research contents of rock mechanics, but also have important practical value for railway construction and water power development in mountain regions.

结合滇藏铁路滇西北段线路比选和优化工作，对云南玉龙雪山西麓第四纪冰川堆积物的类型和分布特征进行了详细的野外调查；在室内物理力学试验的基础上，着重研究了冰碛砾岩的胶结物成分与胶结作用、水稳性、力学性质、声波速度等方面的特性，这不仅可以丰富现代岩石力学的研究内容，而且对本区铁路工程建设和水力资源的开发具有重要的实际价值。

The results showed that the average heterozygosity was higher in 9 populations,the lowest is Jinding, the highest is San sheldrake, which ranged from 0.5137~0.6055. The average heterozygosity of 9 duck populations was 0.5523, which reflected the rich diversity. Considerable breed differentiation was observed and 25.65% of the total genetic variation came from breed differences, this result affirmed each breed was of own genetic diversity. The DA genetic distances suggested the longer differentiation existed between those breeds. The domestic duck breeds in East China were clustered into four groups based on the NJ clustering, the clustering results had some relationship with the distributions and economic utilizations of these duck breeds.

结果表明：9个品种的平均杂合度都较高，最低的为金定鸭，最高的为山麻鸭，杂合度范围为0.5137～0.6055，群体平均杂合度为0.5523，反映了各鸭种的杂合度都较高，遗传多样性丰富；华东区各鸭种间存在较大的遗传分化，25.65%的遗传变异来源于品种间的差异，更进一步反映了各品种具有本品种特征特性的多样性；通过计算DA遗传距离发现各群体的遗传距离较远，分化时间较长；NJ聚类结果将华东区家鸭资源聚为4类，NJ的聚类结果分析与几个鸭品种的地域分布和经济用途有一定关系。

Based on field observation and indoor analysis about the stylolites in Tieshan,Daye,Hubei Province,this paper raises some fresh understandings about the stylolite as follows:(1) Stylolite s are classified into wave-shaped,sawtooth-shaped,city-wall-shaped and thin-column shaped stylolites.

为深入研究碳酸盐岩中的压溶作用，加深对压溶作用的认识和理解，以常见的缝合线构造为例，结合前人的研究成果和现代科技手段对湖北大冶铁山地区的缝合线构造进行了全面深入的研究，得到以下研究成果：丰富了缝合线类型；结合计算机技术获得了缝合线的三维形态；总结了缝合线形成中的一些主控因素；论述缝合线在应力分析、应变测量等传统领域及在能源资源等新领域的应用；对缝合线研究中存在的问题及分歧进行了评述并指出今后几年的研究重点。

A bstract: this system main contents is launching under the discussion of book sale management system, which main aim at a book batch to sell and retail sales sale is lord but carry on designing , in keeping with book's sell retail of management, specially be applicable to book market and book batch resources that sell company's coordination management.the system source code adopt c# language by writing format and in the vs.net 2005 integration environment bottom adjust to try to carry on, the sql server of the database adopt be 2000 backstages.it's system's turn to is a great deal of adoption abundant database technique, have already aim at a mold piece line of development, among them database operation layer technique a great deal of adoption saving process and trigger a machine of application, database interview layer technique adoption microsoft company of ado.net latest 2.0 development technique, the database mean a layer adoption unify of external appearance mode, make thus the whole system structure clear in meaning, the source code self own very good performance of readability and writability, then better convenience to customer operation and development personnel next move of development work, the type of tree control and user-defined page technique of usage make the whole system person's machine hand over with each other the function be more outstanding.

本系统主要内容是围绕图书销售管理系统而展开讨论的，主要针对图书批销以及门市销售为主而进行设计的，适合图书进销零售的管理，特别适用于书城及图书批销商协调的资源管理。系统源码采用c#语言书写格式，在vs.net 2005集成环境下调试进行，数据库采用sql server 2000后台。该系统大量采用了丰富数据库技术，有针对性模块行的开发，其中数据库操作层技术大量采用存储过程及触发器的应用，数据库访问层技术采用微软公司的ado.net最新2.0开发技术，数据库表示层采用统一的外观模式，从而使得整个系统架构明晰，源码可读可写性好，进而更好的方便了用户的操作及开发人员下一步的开发工作，树型控件和自定义分页技术的使用使得整个系统人机交互性能更为出色。

Skin-the-Goat, assuming he was he, evidently with an axe to grind, was airing his grievances in a forcible-feeble philippic anent the natural resources of Ireland or something of that sort which he described in his lengthy dissertation as the richest country bar none on the face of God's earth, far and away superior to England, with coal in large quantities, six million pounds worth of pork exported every year, ten millions between butter and eggs and all the riches drained out of it by England levying taxes on the poor people that paid through the nose always and gobbling up the best meat in the market and a lot more surplus steam in the same vein.

&剥山羊皮&——假定就是那位老板——显然是别有用心。他以色厉内荏的申斥口吻，就爱尔兰的天然资源问题什么的，发泄了一通牢骚。他在一席冗长的论说中描述爱尔兰是天主的地球上无与伦比的富饶国家，远远超过英国，煤炭产量丰富，每年出口的猪肉价值六百万英镑，黄油和鸡蛋则共达一千万英镑。但是英国却向爱尔兰的穷苦人民横征暴敛，强迫他们付出惊人的巨款，并把市场上最好的肉掠夺一空。另外还说了不少诸如此类夸张的话。
