图示四杆连杆机构中,OA=O1B=AB2.曲柄OA以匀角速 度a=3rad1s绕O轴转动,图示瞬时φ=90°。O1B与OO1在 一直线上。求此时杆AB和杆O1B的角速度

城市污水一般由生活污水和工业废水组成,城市污水的水质与城市的规模、生活水平、 工业企业的状况及废水处理水平、排水系统的形式及完善程度气候环境等因素有关。主 要水质指标为:水温一般在10~20℃,CO为200~500mg/L,BOD3为100~300mg/L, pH=6.5~7.5,S=100~250mg/L,可生化性较好,各种营养物质齐全,对一些有毒有害 工业废水必须进行预处理后才能排入城市下水道,以免对城市污水处理系统造成冲击

含有赋值运算符的表达式叫做赋值表达式。其一般形式为: variable s expression 可以看出,在赋值表达式中,赋值运算符的左操作数必须是 个变量,而右操作数可以是任一合法的表达式。赋值表达 式的值就是其右操作数的值 由于赋值运算符要求其右操作数为一个表达式,而赋值表达 式是一个合法的表达式,所以可以将赋值表达式用做赋值运 算符的右操作数,从而构成所谓的“串连”赋值表达式

Eco514 Game Theory Problem Set 1: Due Friday, September 30 oTE: On the“ethics”of problem sets Some of the theoretical exercise I will assign are actually well-known results; in other cases, you may be able to find the answer in the literature. This is certainly the case for the current problem set. My position on this issue is that, basically, if you look up the answer somewhere, it's your problem. After all, you can buy answer keys to most textbooks... The fact is, you will not
