本文主要论述我国高速动力车转向架二系悬挂高圆簧的配置选择,在保证二系悬挂性能指标的基础上,提出了每台转向架布置六组高圆簧的方案,并将该方案与德国ICE高速列车驱动转向架二系悬挂高圆簧布置方案进行了分析比较,证实了ICE驱动转向架二系悬挂高圆簧的布置方案和结构设计是合理的。
4)  two-line-method
二系法
1.
On the other hand, the two-line-method uses photoactive caryonic male sterile line as the maternal, fertility restore line with dominant marker gene as the paternal, and needs no breeding of sterility maintainer line.
对三系法和二系法杂交育种进行了比较,结果表明,三系法是一种行之有效的传统育种方法,但它必须要三系(不育系,保持系,恢复系)配套,增加了育种的时间和资金;而二系法选用光敏核不育系的自交不育系做母本,用加显性标记基因的恢复系作父本,省去了繁殖保持系的工作,同时,这种不育系会因光照长度或温度高低(或两者兼有)而在可育与不育之间互相转换,而这些条件都可以人为控制,这既保证了杂种优势的利用,又节省了资金,是一种具有广阔前景的育种方法。
5)  the secondary load
二系载荷
6)  two out of three system
三取二系统
