1·A torsion difference scheme of the bar with sectorial cross-section is developed in polar coordinate system.

导出了极坐标系下扇形截面杆件扭转问题的差分格式；用逐次超松驰迭代法求出了扭转应力函数差分值。

2·However, it is not intended as a complete reference for comprehensive assessments conducted by sectorial experts.

不过这并不能作为领域专家做全面评估的完整参考。

3·In the model, the basic grids are sectorial ones, but the source area and near source area is regularly shaped to rectangular grids.

该模型采用扇形网格和正方形网格相结合，以扇形网格为基本框架，而将面源区和近源区划分成正方形网格。

4·From these dynamic solutions, frequency and mode shapes of sectorial plate and sectorial annular plate under boundary conditions of GSS and GRS are derived.

由动力学的一般解，导出了扇形板和扇形环板在广义弹性简支和广义刚性滑动边界条件下自由振动的频率方程和振型；

5·When sectorial experts such as epidemiologists and sanitarians are members of the Assessment Team, they will provide more specific materials related to conducting their portion of the assessment.

当特殊领域的专家，比如流行病学家和公共卫生学家，是评估小组成员的时候，他们会为他们评估的部分提供更具体的有关资料的。
