Ccording to the philosophical standpoint of the system theory,this thesis discusses the question of the cognation and method theory of the slab structure doctrine which is the leading theory of the modern geological science,and analysises the existent four essential theroetical diffiCulty.

Firstly, according to electromagnetic field theory, the 2-dimensional (2-D) mathematical model of a three phase squirrel-cage Y802-2 induction motor is developed. Then general equations can be deduced from finite element discrete and functional analysis. The motor's 2D solving region of electromagnetic field is given based on the boundary conditions and assumption conditions of the squirrel-cage induction motor. Through finite element mothod and inner–outer convergence method, magnetic field distributions and magnetic forces of bars can be calculated in following rotor conditions: health rotor, one single broken bar, two adjacent broken bars, two broken bars with one good interval, two broken bars with two good interval and four adjacent broken bars.

The system utilized four laser scanners along lengthwise direction of the log. Data are obtained in every ten degrees when log is turning, in each cross section, 36 data are obtained. Then the data obtained were processed and an outline of the cross section of the log was developed on computer screen. Afterwards, the largest inscribed circles for log cross sections were determined according to the principle that three points can determine a circle. Secondly, the points located on the cross sections were linked up along some log generative in order to simulate the three-dimension log outline. At last the largest right circular cylinder were optimized and the optimum turning center was determined by means of projective theory.

具体作法是：在木段长度方向均匀设置四个激光传感器，当木段旋转时，起动激光传感器，进行数据采集，每隔10~0扫描一个点，在各横断面圆周上共采集36个点的数据，由计算机处理采集的数据，并绘制出原木横断面的几何图形，再根据三点定圆的原理，确定出最大内接圆；其次，模拟原木三维廓形，即将原木相邻横断面上离散点沿着母线方向连线，由计算机分析处理，绘制原木三维廓形；最后，采用投影法，优化出原木最大内接圆柱体，并确定原木回转中心线。

The Samara Sutradhara is a scientific treatise dealing with every possible angle of air travel in a Vimana. There are 230 stanzas dealing with the construction, take-off, cruising for thousand of miles, normal and forced landings, and even possible collisions with birds. In 1875, the Vaimanika Sastra, a fourth century B.C. text written by Bharadvajy the Wise, using even older texts as his source, was rediscovered in a temple in India.

Samara Sutradhara是一篇涉及用维曼拿空中旅行的每一种可能，有230节是有关构造，起飞，巡航一千里，普通和紧急降落，甚至可能碰到鸟类。1875年，一本由智者巴拉瓦杰在公元前四世纪写的《维曼尼卡萨塔》，甚至在他的内容里面引用更古老的资料，在印度一座庙宇里重新被发现。
