The nonlinear hyperbolic conservation laws of the transient flow of the media in gas pipeline are hard to he solved, so, the control conservation laws are constituted of mass, momentum arid energy conservation laws, TVD/Godunov hydrid algorithm is used to simulate the transient flow in gas pipeline, and the traditional splitting approach processing nonlinear convection in momentum equation is dismissed ,the convection tern; is directly processed, in the way, the stablization of the algorithm and emulating accuracy of the transient flow are greatly improved.

针对管道中介质瞬变流动的非线性偏微分方程组难以解析求解的问题，由质量、动量、能量三个偏微分方程构成的控制方程组，应用TVD/Godunov混合算法数值模拟天然气管道中气体的瞬变流动，摒弃了传统的差分方法时动量方程非线性时流项的线性化处理，而直接处理非线性对流项，从而大大提高了算法的稳定性和管道瞬变流动的仿真精度。

This thesis researches on the choices and fixing of the instruments, the H- ADCP' s velocity representation of observing, the control system software etc; taking the successful invent of the tidal discharge automatic observing system in Tianhe hydrometrical station in the Pearl river delta as an example, and expounds the constitutes, function and working process of the tidal discharge observing system in the tidal river.

On the base of the brief description of the drive and control system of micro-fluid and the experimental setting of the technology of micro-injection, a novel process of the hydrophobe treating used to mend the characteristic of the inner and outer surface on micro-pipette is designed, which can improve greatly the injected effect and eliminate the disadvantage such as seepage or regurgitation during injection. The author puts forward the way of measuring the inside diameter of the micropipette. The program of measuring micro injection amount is designed. The original data of the micro injection experiment are explained and interpreted at last in the thesis.
