钱学森在现代人类知识体系11个门类中,将地理科学归结为自然科学与社会科学之间的桥梁科学;在五大开放的复杂巨系统中,把地理系统排在星系系统与社会系统之间;在社会总体设计部下设四大建设中,将地理建设与政治文明、物质文明、精神文明建设并列。钱学森把地理科学看做是举足轻重的科学体系。钱学森从哲学高度,从人类知识体系的高度,从复杂性系统科学的理论框架中,从社会总体设计工程的实践出发,把地理学提升到为国民经济服务的科学,因此,地理科学具有重要的理论与实践意义,必须重新认识地理。

This paper presents a new calculation method that can calculate the load distribution on pipe threaded connections under tension load. On the basis of elastic mechanics, the new method was developed by analyzing each thread tooth, and a new deformation and covariant equation by making a mechanics analysis on each thread tooth was obtained. Compared with the traditional method proposed by the previous references, the new deformation and covariant equation could be used to describe the relation between the previous and the next thread tooth. By applying the new method on the sample of P-110S pipe threaded connection, the obtained results show that the load on thread tooth mainly concentrates on the four or five threads engaged and the middle teeth were not utilized well to bear the loads. The model offers a new way to calculate the loads carried on the thread teeth under tension load.
