全新一代SH350i则不再沿用以往结构,而是研发出昵称为eSP +的发动机,采用了偏移式汽缸、滚子摇杆、配有滑动轴承的曲柄销、密封式曲轴箱等装置,减少了各种内部摩擦和损耗,确保长时间运行不出现性能衰减。为了提高活塞散热能力,还借鉴了越野车CRF450R,配置了机油喷嘴,对着活塞顶喷机油。
if if是最常用的条件判断结构,只有符合给定条件时,才会执行指定的命令。它的语法如下。 if关键字后面是主要的判断条件,elif用来添加在主条件不成立时的其他判断条件,else则是所有条件都不成立时要执行的部分。 if和then写在同一行时,需要分号分隔。分号是 Bash 的命令分隔符。它们也可以写成两行,这时不需要分号。
