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.

A simple coded modulation technique, which is called "split-phase coded modulation", is studied in this thesis. Such a technique is especially suitable to be applied in a multi-antenna system. To have an insight into the possible transmit diversity benefits to the proposed scheme, here we consider the employment of multiple transmit antennas and a single receive antenna for the considered system.

本论文探讨一个简单的编码调变技术，我们称为「相位分离编码调变」，此编码调变技术特别适用於多天线系统，为了进一步了解这样的架构在「传送分集」上所造成可能的效益，在此论文中，我们假设传输端布署多重天线，但在接收端仅使用单一天线接收。

A new kind of state variable weight vectors can be constructed by means of the properties under some conditions.

首先讨论了状态变权向量的基本性质；然后，指出在满足一定的条件下基于这些性质可以由已知的状态变权向量构作新的状态变权向量。

After the introduction of brand into economics, the elevation of brand credit changes the demand curve. On the one hand the elevation of brand credit will decrease the choice cost of consumers effectively if other conditions remain unchanging. Consumers' nature of hastening for benefits and avoiding harm makes the demand increase at any price. On the other hand the elevation of brand credit will reduce merchandise demand elasticity and steepen the demand curve.

把品牌引入经济学后，品牌信用度的提高使得需求曲线发生变化，一方面在其他条件不变的情况下，品牌信用度的提高将有效地降低消费者的选择成本，消费者"趋利避害"的本性使得在任意价格下需求量增加，需求曲线右移；另一方面品牌信用度的提高使得品牌商品的需求弹性变小，需求曲线变陡峭。

Based on Bellman stochastic nonlinear dynamic programming, we develop an optimal control algorithm for the discrete stochastic system with conditional Markov structure.
