As we all know,there is one Simson line at any point on the circumference of triangles,but in this paper, LHP theorem shows that the above conclusion is not correct for any quadrilateral pyramid in three-dimensional space and also during proving LHP theorem,fixed value theorem is proved,at the same time,one guess about the point H and point P on circumscribed sphere of tetrahedron has been concluded.

众所周知，三角形的外接圆周上任一点存在一条 simson 线，而 LHP 定理则指出对于正四面体该结论是不能推广到三维空间上的，并且在论证 LHP 定理的过程中得出了定值定理，同时作为一般四面体的外接球球面上的 H 点、P 点的分布，给出了一个猜想。

During this process, the spherical polar coordinate transformation and the circle polar coordinate transformation are used to carry on the pretreatment for the historical data about investment ratio and investment accumulation rate of the three industrial sections, and the consequent data also be simulated by statistical software-SPSS12.0; Finally, sensitivity analysis according to investment ratio and the fixed assets investment accumulation rate of the three industrial sections are made and a better resource distribution plan for the three industrial sections also be given.

在预测的过程中，利用球面极坐标变换和圆极坐标变换分别对三次产业投资比例和积累率的历史数据进行预处理后，再利用统计软件SPSS 12.0进行拟合；最后，利用固定资产投资的积累率和三次产业的固定资产投资比例进行灵敏度分析，提出了一个较好的三次产业经济的资源分配方案。

We can think of spherocylinders as a flat sphere and a flat cylinder glued together. They have power meridians of maximum and minimum , called primary merdians.
