Based on the Jiles-Atherton model, the dynamic hysteresis loss model of the transformer core considering the classic eddy current loss and abnormal loss is developed, which is suitable for all the reasonable coefficient of reversible magnetization and adopting the flux density as entry variable.

该文在Jiles-Atherton基本磁滞模型的基础上，从能量平衡原理出发，考虑铁心在交流状态下的涡流损耗和异常损耗，建立了合理可逆磁化系数条件下，以磁通密度作为输入量的铁心动态磁滞损耗模型。

The results: the phase transferring range of TiO2 is between 600-750℃; with the doping of tourmaline, the UV-VIS adsorption spectrum of Nd/TiO2 was basically not affected, and showed a gradual Einstein shift with the increase of calcined temperature between 300-750℃; OH intensity of Nd/TiO2 could be enhanced both in irradiation and in no irradiation when tourmaline was added in it; the doping of 0.6% tourmaline led to the best photocatalytic activity of Nd/TiO2 and the best photocatalytic effect appeared when calcined at 600℃.

结果发现TiO2的相变转化区间在600~750℃范围内；电气石掺入对Nd/TiO2材料的光吸收范围基本没有影响，在300~750℃范围煅烧后，随温度升高UV-VIS图谱有逐渐红移现象；电气石的加入使得Nd/TiO2材料在光照及未光照条件下都起到增强OH强度的作用；在Nd/TiO2材料中掺入0.6%的电气石获得最好的光催化活性，600℃下煅烧光催化效果较优。

The result makes clear, the basic technology condition of powder of CaB_6 of preparation of system of CaCl_2 frit salt is: AR enrages environmental protection, electroanalysis voltage 3.0 V, 900 ℃ electroanalysis 30 H.

结果表明，CaCl_2熔盐体系制备CaB_6粉末的基本工艺条件是：Ar气环境保护，电解电压3.0 V，900℃电解30 h。

In the process of electro-membrane filtration, the applied operation condition and membrane do not have significant electroosmosis effect through related experiment. Under the operation of 98KPa pressure, only 6% flux was increased, which showed the increase of flux in the applied electric field process mainly from electrophoresis effect. The effect of dye filtration by membrane is mostly influenced by the basic nature of dye, including size of molecular weight, electrophoresis motility and the adsorbability of dye to membrane.

在外加电场薄膜程序中，所用的操作条件以及所使用的薄膜，经电渗透实验显示电渗透的效应不明显，而在98KPa压力操作下，也仅增加6%的通量贡献，显示外加电场程序通量之提升主要来自电泳作用；薄膜过滤染料的效果主要受到染料基本性质的影响，包括分子量大小、电泳动能力与染料对薄膜的吸附能力。

As the Major, mostly learning ANSYS software, which include ANSYS elementary operation, model establishment, grid division, infliction of load and boundary condition, hypothesis of resolver, analysis processing method of computed result and so on.

主要学习ANSYS软件，包括ANSYS的基本操作、模型建立、网格划分、载荷和边界条件的施加、求解器的设定、计算结果的分析处理方法等。

At concretion means , these mostly adopt systematology route to proceed inquisition, on the basis of reference both here and abroad production, compare objectively analyses technological change with agriculture surplus labor transfer of compartment correlation, by the major premise of science and technology, handle science and technology philosophy, sociology, management science, statistics, economics, mathematical statistics, demography , and so on .compare overall systematically approach the feasibility, reliability, elementary path of agriculture surplus labor transfer under conditions of scientific-technical progress .

运用科技哲学、社会学、管理学、统计学、经济学、数理统计、人口学等学科的知识，比较全面系统地探讨了在科技进步条件下，农业剩余劳动力转移的可能性、可行性、基本路径等。

Second, based on binary search, an efficient algorithm is proposed for finding aset of elementary siphons given a set of strict minimal siphons of a Petri net.

第二，在已知Petri网中部分或全部严格极小信标的条件下，提出了一种基于二分法原理确定一组基本信标的快速算法。

As a result, the concept of an optimal set of elementary siphons is proposed and also the algorithm which can be finished in polynomial time to find such a set. With the set of optimal elementary siphons, net supervisors can generally produce maximalreachable states.

但是上述理论虽然只需要控制基本信标即可以控制整个系统，但是由于从属信标满足一定的可控性条件才能完全受控，这意味着在控制算法的生成过程中所有的信标都要参与，从而大大增加了系统控制的复杂性。
