As a result, the micromirrors will be adhesioned to the underlying substrate, because of the large area of segmented deformable mirrors and surface tension of water, after the micromirrors are dried, if the elastic forces can not overcome the surface tention.Secendly, several different procedures commonly used to rinse and dry released micro cantilever beams are compared: evaporation drying with deionize water or methanol, sublimation drying with t-butyl alcohol.

结果发现，由于MEMS微变形镜上极板的面积比较大，在工艺最后清洗的过程中，由于表面张力的作用，上极板极易与下极板接触，干燥以后，如果弹性回复力不能克服各种表面应力，MEMS微变形镜将发生释放粘附。

In Gregory scheme, not only the importance of the moist static energy is taken into account, but also the common difficulty of the moist convective adjustment scheme, the determination of the temperature profile, is obviated. At the same time, it can give the vertical profile of the apparent heat source Q〓 and apparent moisture sink Q〓. Gregory scheme has the clear physical image that includes the cumulus updrafts, cumulus downdrafts,cumulus induced subsidence in the environmental air, entrainment,detrainment and evaporation. In addition, the interaction between the cumulus and the environment is described by one-dimensional bulk model. It is simpler than the Arakawa-Schubert scheme and has no difficult to decide the spectrum of clouds accurately.It is propitious to operational use because of its simple calculation. Finally, Gregory scheme is not only suitable for moist convection of all types, but also for dry convection.

在该方案中，既强调了湿静力能能量的重要性，又回避了给定临界温度廓线的困难，并且还能给出真实的视热源Q1，视水汽汇Q2的垂直廓线；同时Gregory方案又具有很清晰的物理图象—积云中的上升运动，下沉运动，环境中的补偿下沉运动，以及卷入，卷出和蒸发等；此外，Gregory方案用总体云群模式来描述云与环境的相互作用，比型积云参数化方案简单，它避开了型方案中云谱需要精确设置的麻烦问题，计算容易，简便；最后，Gregory方案在湿对流中适用于浅，深，中不同的对流深度，并且也适用于干对流过程。
