Ozone vertical distribution probe is one of the aviliable loads of FY-3 satelite. It is an important work to check up its radiance calibrations precision,instrument precision ,statoscope and dynamic rage at the endgame of its meanufacture.

长春光机所研制的FY-3气象卫星臭氧垂直探测仪和北京空间中心研制的FY-3气象卫星臭氧总量探测仪是FY-3气象卫星两个主要有效载荷，为保证两载荷在轨运行期间重叠数据的一致性，正样研制前对其进行光谱辐照度和光谱辐亮度定标精度、仪器精度、灵敏度、动态范围等性能的验证是十分重要的环节。

From the lifespan of relay point of view, a reliability criterion was provided based on dynamic characteristics of anti-forces. Mathematical model of tolerance design with reliability was set up under usage of "stress-strength interference method", taken some critical dynamic characteristics as identification objects such beginning of contact separation speed, speed of collision and gag bit impact velocity. This model showed that lower values of characteristic parameters center and quantitative descriptively relationship between tolerance and product reliability. Multi-objective optimization model of relay tolerance distribution was completed when some factors such as reliability, processing costs and its feasibility into consideration. Based on Analytic Hierarchy Process to determine weight coefficients of various objectives, and usage of simulated annealing, this study performed optimal reliable tolerance allocation of space electromagnetic relay, and then key technology segments were analyzed, accompanying its course measured by controlling chart.

从继电器电寿命的角度，基于动态吸反力特性的配合提出了继电器的可靠性判别准则；在此基础上以触点分离初速度、触点碰撞速度以及衔铁碰撞速度等关键动态特性为判别对象，采用"应力-强度干涉法"建立了继电器可靠性容差设计数学模型，给出了下位特性参数中心值及其容差与产品可靠度之间的定量描述关系；综合考虑可靠度、加工成本及加工可行性等因素建立了继电器容差分配的多目标优化模型，基于层次分析法确定了各目标的权重系数，并采用模拟退火法实现了航天电磁继电器的可靠性容差最优分配；研究了继电器的关键工艺环节，并通过控制图对其过程能力进行了分析。

Data flow was designed particularly for distribution center and trattoria, besides ,the function of trattoria part was come true.

对各个环节的管理进行分析，提出了一些管理的对策和建议，重点设计了配送中心的数据流动框架，并实现了餐饮店部分管理系统的功能。

Taking the wineshop of the International Business Center of Chinese Light Industrial Good and Textiles Mall as the example, this paper introduces the construction process of pouring concrete into square steel tube column , and advances some suggestions on some key links in the construction.

The integrative ability, organizing ability, communicative ability of trainings was deficiency. Fourthly, the power of social physical educators in Guangxi universities was so weak that it couldn't satisfy the need of specialty development. For example, the number of special teacher and the practicing ability of teachers are deficiency. The teachers that master special theoretic well and have practicing experience are deficiency especially. Fifthly, social physical practice base have not been building in Guangxi universities. And the necessary equipments of gymnasium are deficiency at the same time. Sixthly, the whole sports technology levels of new social physical students are low and hard to fit for social needing. Seventhly, the professional ideology of students is not stable enough. For example, the special concept and cognition of students are dim. The attitude for learning is not right. The most of students want to or have trend to change their profession after graduating. Eighthly, the ability of students fostered by social physical education in various Guangxi universities has a gap with the ability that students should hold for adapting the need of Guangxi employer. The special technical levels of social physical students are weak. Ninthly, in investigation of social physical personnel being demanded by Guangxi area employers, we found that few social physical personnels were demanded by business unit, the state-operated factory and mining enterprise because of being influenced by economical environment. And the more social physical personnels were demanded by social physical directors, fitness centers and each kind of sports association and so on.

这主要表现为：不够科学的课程体系，在实践性教学环节中的重视程度不够，对学生的综合能力、组织管理能力、社会交际能力的培养较为欠缺；4、对社会体育专业的发展需求这一点而言，广西各高校该专业的师资力量还略显薄弱，难以满足社会的需求，主要体现在：缺乏足够的专业教师数量、教师实践能力欠强，尤其缺乏既有较高理论素养又有实践经验的教师；5、社会体育专业的实习基地在广西各高校中都尚未建立起来，同时一些必备的体育场馆的设施也较为缺乏；6、由于入学时广西社会体育专业的学生在运动技术、技能整体水平相对较低，因此在一些专业方向的需求上难以达到满足；7、在专业思想这一方面而言，广西各高校社会体育专业的学生显得不够稳定，主要表现为：淡薄的学生专业观念，模糊的专业认识，不够端正的学习态度，甚至有相当一部分学生准备毕业后改行或有改行倾向；8、广西各高校社会体育专业培养学生目前所具备的能力与当前广西用人单位所需求的社会体育专业人才应具备的能力尚有一定差距，主要体现在：目前社会体育专业学生的专业技术水平较低，组织能力和社会交际能力较为欠缺等。9、在广西地区用人单位对社会体育专业人才需求量的调查中发现：大多数的企事业单位和国营厂矿企业因受到经济大环境的影响，基本上都不设置专职的体育管理人员，对社会体育专门人才的需求量较少，需求量较大的还是社区体育指导员、体育健身中心、各种体育协会等。

It was founded that the hardness distribution is approximately symmetrical to the center of welding line , the weakest zone of the whole joint is about 10mm from the center of the welding line .

Self-regulated writing teaching for keeping a weekly diary is a newly-constructed writing teaching style inspired by the idea of the new curricula ,which attempts to change the monotonous state of being teacher-centred ,the separation of content and form from real life and from the studrnts ' interest and teaching situation. The links of self-regulated weekly diary keeping requires the students to mind themselves and society and the effect of knowledge, ability and virtue will be taken into comprehensive account. And the students are requested to allow full play to their initiative, enrich their emotions throughout the self-regulated atmosphere, accumulate knowledge and improve ability.

自主性周记写作教学正是基于新课程理念的基础上建构起来的一种新的写作教学方式，力图改变传统写作教学中的以教师为中心，内容与形式脱离生活实际，脱离学生兴趣及教学情境单调的现状，在自主性周记写作的各个环节中，它要求学生关注自我，关注社会，综合考虑知识、能力与情操等三方面因素的作用，充分发挥学生的主体性，学生自始至终都在自主的氛围中丰富情感、积累知识、提高能力。
