In object-oriented (51) , objects can be viewed as reusable components, and once the programmer has developed a (52) of these components, he can (53) the amount of new coding required. But (52) a (54) is no simple task because the integrity of the Original software design is critical. Reusability can be a mixed blessing for user, too, as a programmer has to be able to find the object he needs. But if (55) is your aim, reusability is worth the risk.

在一定温度和压强下,向盛有足量X的体积可变的密闭容器中通人Y气体,发生反应:    X(s)+aY(g)bZ(s)+W(g);△H>0

平衡时Z的物质的量与通人Y的物质的量的变化关系如图所示。下列说法中正确的是(     )

A.平衡时Y的转化率为(a/b)%

B.向容器中再加入少量X,则Y的转化率增大

C.再通入Y,重新达到平衡时W的体积分数不变

D.保持压强一定,当原反应在较高温度下建立平衡时,图中θ<450
