To all project practicality, the introduction is given to the operational characteristics, the methods for calculation and the researching actuality of the tail tunnels with sloping ceiling underground hydropower stations the Three Gorges. This paper has discussed in detail the characteristic method being the same with the compressive flow and the Priessmann solution being the same with the free-surface-pressure flow. And how to deal with boundary conditions has been expatiated. Also hydraulic transient process of tremendous load fluctuation in the tail tunnels with sloping ceiling has been numerical simulated and the Fortran program for numerical simulation has been given. The paper gain the maximal press for tail end of the shell, the maximal rising rate of rotational speed of generating set, the maximal vacuum degree for inlet of the tail tunnels and so on under 11 kinds conditions of tremendous load fluctuation. These conditions include the design conditions, the check conditions and the superposition conditions. Finally, the computing results have been analyzed and summarized. The end chapter is the general comment of the whole-length content and the describing of the intending view of researching.

The altostratus base is 2 km high, and cloud top is higher than 5 km. The supercooled water exists abundantly in the cloud, the maximum is up to 0.21 g.m-3 at -11.20℃, but its distribution is not homogeneous, 87%of continuous distribution width are less than 2.4 km, which is disadvantage to the rime increasing of ice crystal in the cloud. Meanwhile, the evaporation effect of subcloud raindrop is very big, the diameter of raindrops which could not arrive the ground is less than 1 mm. Therefore, The cold vortex process produces the weak precipitation.
As云底高2 km,云顶高大于5 km,云中存在比较大的过冷水区,-11.2℃时的过冷水含量0.21 g.m-3,但过冷水的含量分布极不均匀,大于0.05 g.m-3的过冷水区连续分布的宽度87%小于2.4 km,不利于云中冰晶的连续凇附增长;同时云下雨滴的蒸发效应大,直径小于1.0 mm的雨滴难以落到地面,因此本次过程只产生弱的降水。
