The function that I am integrating is x times delta where density will be given to me maybe as a function of x and y.

被积函数是x*δ,密度可能会由x和y的一个函数给出。

Finally, we design systems of CRL, Delta-CRL, segment CRL and over-issued CRL, offer a CRL encode and decode function interface.

最后，本文详细设计了证书撤销列表CRL以及增量CRL、分段CRL、重复颁发CRL体系，给出了证书撤销列表的编解码函数接口；

Space debris delta-velocity probability density function was deduced by NASA's standard breakup model, and time integral algorithm of collision probability between spacecraft and any debris was built.

推导了基于NASA标准解体模型的碎片分离速度概率密度函数，建立了计算航天器与单颗碎片碰撞概率的时间积分算法。

And of course, in either case, w delta u is q plus w, so it's q irreversible plus w irreversible, u being a state function it's the same in either case.

当然了，在这两个过程中，Δu都等于q加，因此现在是q不可逆加w不可逆，同时u在这两个过程中都是态函数。
