The quest for pension reform : poland ' s security through diversity 波兰多支柱的社会保障体系
Landing gear with multi - wheels and multi - struts was put forward shortly after the occurrence of tricycle landing gear 多轮多支柱起落架是在前三点式起落架的基础上发展起来的。
Occupational pensions are an important part of multi - pillar pension scheme , which are still on the starting stage in china 企业年金是多支柱养老保险体系的重要组成部分,在我国尚处于起步阶段。
In addition , considering the distribution characteristics of the landing gear mentioned above , the equations used to calculate the forces of its stroke absorbers as well as its tires are presented in detail in the paper 同时,结合所研究的多轮多支柱起落架的布局特点,较为详细地介绍了该飞机的缓冲系统各分力和轮胎力的计算方法。
At last , the researchers discussed and analyzed the results of the simulation contrastively . firstly , according to the conditions of the aircraft being researched , differential coefficient equations of the aircraft during its symmetric landing are established systemically in this paper 文章的主要内容包括:以某多轮多支柱飞机的起落架为例,依据该起落对称着陆的实际情况,系统地建立了该飞机的全机着陆动力模型以及飞机主起落架数学模型。
