Curriculum theories such as elementalism , encyclopaedism , polytechnicalism and pragmatism provide a theoretical basis for constructing the school administration teaching material system and lead us to reflect on this problem from two dimensions : 1 what the school administration teaching materials generally describe should represent a complete framework for school administration activities and a typical knowledge scheme 2 the content of school administration teaching materials should not only contains the explicit knowledge of school administration activities but also provide an implicit knowledge to help readers make transformation between the two .

要素主义课程论，百科全书主义课程论，综合技术主义课程论和实用主义课程理论为我们提供了构建学校管理学教材体系的理论基础，引导我们从两个维度来思考构建学校管理学教材体系问题：一是学校管理学教材所描述的整体应该构成学校管理活动的完备的框架和典型的知识脉络，二是学校管理学的教材内容不仅要凝练学校管理活动中的显性知识，还要映射学校管理活动中的隐性知识，帮助读者实现隐性知识和显性知识之间的转换。

Within this context, four specific areas are addressed:(1) By means of finite integration technique, a new kind of the first order partial difference equation is derived from the original disperse transmission line equation of the uniform waveguide's. As it is the kind of one dimension Dirichlet's boundary problem, it is convenient for us to solve this equation from the leapfrog scheme. Because computation is carried out in one dimension, both high calculation efficiency and precision have been obtained in this method. Meanwhile, this method provide us a different selection to simulate the transient response of waveguide with non-simplical, for examples cylinder and elliptic waveguide, and avoid solving the second order equation, or using finite difference time domain to simulate a three dimension problem, sometimes the latter precision is not satisfied with the need, or low efficiency.

在这一研究内容下，主要研究四个方面的问题：(1)在完成金属波导传输线方程时域形式的基础之上，应用有限积分技术，把波导特征模式的色散传输线方程，化简为一组新的一阶偏微分方程组，该边值问题属一维Dirichlet边值问题，从而便于用蛙跳格式求解，由于是在一维中计算，该方法具有很高计算效率和精度，从而避免了以往为得到金属波导中特征模的时域响应特性，须要求解二阶方程，或用时域有限差分方法求解三维问题的方法，对于后者来说，计算有时是不准确的，或是很耗时的例如计算诸如圆波导、椭圆波导等其它复杂形状的波导。
