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。

Among them, 20 patients were candidates of valve replacement and 18 PDA and pericarditis had their blood samples taken before operation,and 1,2,24 and 48 hours after closure of thorax for measurement of concentrations of CK、CK-MB and TnT,together with ECG recording. Results Of the 60 patients, concentrations of cTnT before operation were normal; 2 hours after aortic unclamping, the correlation coefficient between cTnT and aortic clamping was r = 0.873( P＜0.01), the regression analysis showed Y = 0. 019X-0. 026. Of the 20 patients, ECG showed the myocardium was ischemic; CK、CK-MB and cTnT all rose significantly, reaching the peak after closure of thorax. Of the 18 patients, the ECG and cTnT before operation and after closure of thorax were normal; except 2 patients with pericarditis.

结果 60例瓣膜手术患者术前cTnT均在正常值范围内，主动脉开放后2 h时，阻断时间和cTnT的相关系数为r=0.875(P＜0.01)，回归方程为Y=0.019X-0.026；其中20例瓣膜手术患者心脏经过阻断后，心电图有缺血性改变，周围血液中的CK、CK-MB和cTnT均有明显升高，分别在关胸后2 h达到高峰，数值分别为术前的12.6、9.2和257倍；18例行动脉导管结扎和心包剥脱术的患者术前和关胸后的心电图和血液中的cTnT均正常，CK和CK-MB除2例心包炎患者关胸后出现明显变化外，余均未见改变。
