The left ventricular internal dimension at end diastole, interventricular septal thickness at end diastole and left ventricular posterior wall thickness at end diastole were measured in the parastemal long axis view by transthoracic two-dimensional echocardiography, and to calculate left ventricular ejection fraction with Teichholtz formula and left ventricular mass with modified Devereux formula, left ventricular mass index=LVM/body surface area. From the apical four chamber and two chamber view, the basical segment and middle segment of interventricular septal, left ventricular lateral wall, anterior wall and inferior wall were obtained by tissue Doppler imaging, Regional left ventricular relaxation asynchrony index was calculated.

At 2years after OPBPV,right ventricular end-diastolic volume and end-systolic volume were still significantly bigger than control group (P ＜0.01) in all patients but right ventricular ejection fraction was normal,RVEDV dilatant rate correlated very well with DB/Dp ratio significantly.

RVEDV较未手术组的扩大率与球/瓣比间有非常显著相关(P＜0.01)，RVESD扩大率与球/瓣比间有相关趋势，但球/瓣比与术后即时、3月、＞2年的ΔP↓率间无显著相关(P＞0.05)。

According to our present broadcasting situation,the thesis proposes using new technology to update and reform the present HFC. It also suggests broadcasting using self-advantage and arranging EPON in order to win the supermarket.

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.

考虑缩合水的排除对反应体系的影响，用体积浓度单位推导出一个新的聚酯反应总包动力学方程，并应用到AA/HPHP和AA/NPG两个聚酯化反应的动力学研究中，研究发现，自催化聚酯反应的反应级数并不是固定值，对于AA/HPHP和AA/NPG两个聚酯化反应而言，低温时反应级数为2.5，高温时反应级数为3.0。
