2 . the arc erosion of cuw70 / crcu integrated contact is first from the even volatilization of the surface cu , following by the formation of a w shell on the surface of w skeleton , then the shell flake off , after this , new arc erosion occur ( 2 ) cuw70的烧损先是表层的cu均匀挥发，接着在骨架的表面形成一层以w为主的壳层，然后壳层剥落，裸露出来的继续烧损，如此反复，导致了触头的烧损。
The volatilization of filter is solved in simulation environment . four tracking filters are designed by altering the component of observe parameter to detect the effect of different compone nt . all four filters are evaluated in different position of fly envelop 本文采用不同的观测参数设计了四个跟踪滤波器，以检验不同观测参数对滤波性能的影响，在飞行包线不同位置对四个滤波器进行了评价。
Giving out in - depth researches and discussions for the data - processing of aacs , providing the system state equation , kalman filter equation and filter ' s calculate flow , and coming up with the methods to avoid filter ' s volatilization in the paper -对aacs的数据处理进行了一些较深入地研究和探讨，给出了系统的状态方程， kalman滤波方法及计算流程，并对滤波发散的问题作了分析，提出了解决的方法。
This paper introduced the basic theory of zinc leaching residue volatilization kiln , combine with the practice improving on the one system before , and analyzing the causation of the low - level - pollution of zinc leaching residue volatilization kiln , then bring forward a suitable project 摘要文章介绍了锌浸出渣挥发窑的基本原理，结合一系统挥发窑改进，分析了挥发窑低空污染产生的原因，提出合适的治理方案。
Hill equation was often used in the relative navigation between the satellites . but the classical hill equation was restricted by the condition of the initialization . when the condition of the initialization cannot meet , the level orientation will appear volatilization and cannot match with the practice 在卫星的相对导航中hill方程是比较常用的方法之一,但经典的hill方程受初始条件的限制,当不满足初始条件时在水平方向上将会出现发散现象。
Focused on assessment & compensation for oil pollution damage from ships in dalian bay , the dissertation first makes a deep analysis of the inflection factors to oil pollution damage and then evaluates respective mathematical model , such as measurement of oil property , general models for diffuse and volatilization of such substances according to the numerical simulation of the tidal dynamics in the water of dalian bay . based on the corresponding oil pollution regulations , the scope and judgment criteria of oil pollution compensation are laid out . respective compensation measurement methods are developed after those of more mature international practice 文中剖析溢油事故可能造成损害程度大小的影响因素，包括建立石油化学数据库并将油品特性进行量化及通过对大连湾潮流和潮位的计算，建立溢油扩散、挥发模型等；依据现行油污赔偿法规，确定油污损害应予赔偿的范围和判定标准；吸收和借鉴国际上相对成熟的评估技术，建立各项损害的赔偿计算方法；运用visualbasic6 . 0对损害评估部分进行了计算机编程实现。
The mechanism of arc eroding for cuw60 / crcu integrated contact is the volatilization of cu under the arc working , then the particles of w were worn off the matrix , this phenomena is n ' t formed continuous skeleton during the connecting and cutting . such - and - such repeating resulted in the arc erosion of the contact , until invalidation ( 1 ) cuw60触头的烧损机理是以cu首先熔化喷溅，然后没有形成连续骨架的w颗粒在关合的磨损中脱落，这是一个烧损周期，如此的循环导致触头的烧损，直至失效。
The widely used mg alloy zm5 is chose as the original alloy . on the surface of the molten alloy , a layer of protective film with dense structure is formed by the addition of la , ce or mischmetal . the film prevents the penetration of oxygen and volatilization of mg vapor , and then prevents the zm5 alloy from oxidation and burning 针对目前广泛应用的zm5镁合金，通过添加稀土镧、铈和混合稀土，在镁合金液面上形成一层结构致密并且具有耐久性的保护膜，阻止氧气的进一步侵入和镁蒸气的向外挥发，不再产生镁的剧烈氧化燃烧现象。
In addition , the model of interaction of water and temperature between field water vaporization and soil water storage , temperature and millet weight is gotten by field trial . 2 . the ammonia volatilizing of fertilizer is suit to the dynamic equation as y = a + bt , the coefficients in the equation are related to the kind of fertilizer , temperature and water content of soil , and the dynamic equation about ammonia volatilization including water and temperature and the is developed 肥料氨累积挥发量符合零级反应动力学方程y = a + bt ，方程中系数与肥料种类、温度和土壤含水量有关，碳铵a 、 b值均比硫酸铵高，土壤含水量增大， a 、 b值降低，温度升高， a 、 b值增大，并由此得到含温度或土壤湿度因子的肥料氨挥发动力学方程，并建立了含水、热因子的肥料氨挥发水热耦合效应动力学方程。
Nevertheless , use of soil incorporation for urea and anhydrous ammonia to reduce volatilization , the practice of delaying nitrogen fertilizer application in imperfectly drained soils to minimize denitrification and leaching , and patience in the case of immobilization will tend to resolve all these problems 但是，采用把尿素和液氨和土壤掺混施用以减少氨挥发，在排水不良的土壤上采取延迟施氮期的办法以减少反硝化及淋失，以及对于氮固定问题采取耐心克制的态度，这些问题就都能得到解决。
