For explosion process of gas cloud in closed vessels, flow field parameters, such as pressure, velocity, density, temperature, concentration and so on, vary with time and space.

对于球形密闭容器内气云的爆炸过程，压力、速度、密度、温度、浓度等流场参数均随时间、空间而发生变化。

Secondly, parameters must be optimized in lapping process as follows: pressure, rotation, slurry concentration, flow, time.

在研磨工艺中，研磨压力、磨盘转速、磨液浓度、流量大小、研磨时间必须有效配合；

The computing cases show that both the mean discharge process and variance process can be given for the stochastic flow concentration model.

提供的算例表明，对于随机汇流模型，不仅可以给出均值出流过程，而且同时可以给出其方差过程。
