有的著作认为在极限公式limx→0sinxx=1的证明中，要用到圆的面积公式S=21Lr，而对后者的证明中必须要用到重要极限limx→0sinxx=1，从而犯了循环论证的错误。魏晋刘徽的&割圆术&是对无限问题的独特认识和致用的处理方式，是为证明圆面积公式而设计出来的一种方法。

During the process of the fore mentioned analyses, some tentative works as follows were done.(1)On the basis of the fundamental of spatial analytic geometry, the basic method for displaceable block searching was put forward and the relevant program was written. With this program one can easily search out all the displaceable blocks and omitting of blocks, which is very common in searching blocks manually, can be avoided.(2)The coefficient of stability of blocks with failure mode II-2(that is, sliding on a single sliding surface, but confined by near intersecting line )was deduced.(3)The multi-cavern effect of Laxiwa underground caverns was studied on the assumption that all of the caverns were full face tunneled at the same time.(4)The stability classification scheme of rock mass surrounding large scale underground caverns was established. In addition to inherit the merits of the method of engineering geological

在完成上述工作的过程中，本论文主要在以下几个方面进行了一些探索：①基于空间解析几何原理，提出了块体搜索的基本思路并编制出相应的程序，基本实现了块体搜索的自动化，既大大缩短了块体搜索时间，又能防止因人工搜索引起的遗漏；②推导出Ⅱ-2型(单滑面滑动，但受侧限面约束)块体的稳定性系数计算公式；③以数值模拟方法论证了拉西瓦地下厂房洞室群全断面一次开挖时群洞效应的具体特点；④以岩体质量、开挖效应、群洞效应和次生灾害效应为评价指标，建立了&大型地下洞室群围岩稳定性分类&方案；该方案既继承了水电行业规范&围岩工程地质分类&法的优点，又综合考虑了大型地下洞室群的工程特点。

This method is featured with high estimating performance and little computation burden by n o aperture losing and temporal smoothing. The reˉ quirements on hardware for RSDOA matrix method is predigested consu medly only need one fiducially sensor array with arbitrary structure and a single scattered sensor cell, so it is more effective and practical than other existing similar algoˉ rithms.

与现有算法相比较，RSDOA方法对于系统的硬件需求大为下降，计算负担小；由于无阵列孔径损失问题且空时协方差矢量具有时域平滑效果，因此参数估计性能优越，具有广泛的适用性与实际的应用价值。

Aiming at the major influencing factor of the logistics cost of coal enterprise as well as the non-linear characteristic of the coal enterprise logistics cost and the superiority that the neural network has in the solution of complex nonlinear system question, propos to use the BP neural network to do the forecasting of the logistics cost, establishs the forecast model of the logistics cost and do simulation and forecasting by frondose dates, the result indicates the precision of this forecast method is high, the convergent rate is quick, is one feasible forecast method.

重点针对影响煤炭企业物流成本的因素以及煤炭企业物流成本所具有的非线性特点和神经网络在解决复杂非线性系统问题方面所具有的优势，提出了采用BP神经网络来进行物流成本预测的方法。建立了基于BP神经网络的物流成本预测模型并应用具体数据对模型进行了模拟和预测，结果表明该方法预测精度高，是一种实际可行的预测方法。

It is proved that the method using the BEM to calculate the load distributions on the contact lines of involute gear pair, in which the applied load is taken in the form of a concentrated one at a single node, is not suitable. A method in which the tractions of the BEM are made to imitate the Hertzian pressure of the gear using 8 nodes isoparametric elements is introduced.

本文解决了边界元法在空间啮合副计算中存在的系数矩阵的存储，奇异单元积分的计算、表面不连续点处面力一点多值和求解未知量的线性方程组矩阵元素的计算等问题，编制了比不采用上述处理方法的一般边界单元法节省近一半内存和计算时间的适合空间啮合副的三维边界元法计算程序。
