In the computation of aerodynamic forces, the present work is based on the work of Morino et al., but the following aspects are improved:(1) In computing the steady transonic aerodynamic load, the steady transonic nonlinear integral equation is solved by relaxation-iteration method in this thesis, instead of solving the time dependent transonic nonlinear integral equation, so that the computing time is saved greatly;(2) The influence coeifficients represented by volume integral are transformed to surface integral by using the Gaussian Theorem, so the analytical form of these coeifficients can be obtained and this leads to be more convenient to analyse and compile computer program;(3) The shock capturing method is used in every time step in present work, no shock moving term is added in the integral equation, so that it is more convenient and simpler to treat.

在气动力计算方面，本文基于Morino等人的工作，作了如下几方面的改进：（1）在计算定常跨音速流场（作为非定常绕流计算的初场）时，本文采用松驰迭代法直接求解跨音速定常非线性积分方程，而不是采用时间相关法求解非定常非线性积分方程，这样大大节省了计算机时；（2）将以体积分形式出现的影响系数化为面积分，并获得解析公式，这样便于分析和编写程序；（3）对运动的激波，本文通过在每一个时间步长上采用激波捕捉法而得到，而不是在积分方程中附加激波运动项，因而处理起来简单方便得多。

Second, transient flow for vertical well and fractural well in porous media with arealanisotropy has been researched in this paper. The analytic solution for vertical well andsemi-analytic solution for vertical fractural well is developed by using image inversion,superposition principle, Laplace transformation, Fourier transformation, as well as theirinverse transforms, and storage and skin are taken into account. For vertical fractural well,influence of pressure and productivity is studied when the orientation of artificial fractureisn't in accordance with the direction of major permeability, it is fundamental to evaluatepotential and analyze well test data.

Cd〓 (1, 10, 100, 1000μM) stimulated directly GtH secretion from pituitary of common carp in vitro, with the highest GtH secretion at 100μM, GtH secretion stimulated with 1000μM Cd〓 was not higher than that stimulated with 100μM Cd〓.The antagonism between Ca〓 and Cd〓 in perfusion of the pituitary fragments was not obvious.After being preperfusion with 100μM Cd〓(with or without Ca〓), the GtH secretion of the pituitary fragment was irresponsive to 2-min pulse stmulation of 10μM sGnRH-A.

鲤鱼脑垂体碎片离体灌流孵育实验结果显示，Cd〓（1，10，100，1000μM）可直接刺激鲤鱼脑垂体分泌GtH，灌流液中Ca〓对Cd〓的拮抗作用不明显，100μM Cd〓刺激脑垂体分泌GtH达到高峰，Cd〓浓度增加到1000μM时，脑垂体分泌GtH并没有进一步增加，甚至有减少的趋势；100μM Cd〓预灌流脑垂体后，可使脑垂体对2-min 10μM sGnRH-A刺激的反应性消失；1.25mM的EDTA可消除100μM Cd〓刺激脑垂体分泌GtH的作用；TFP和Cd〓同时灌流脑垂体一段时间后，撤除TFP可使脑垂体分泌GtH显著增加，即出现"反跳"现象。
