Results For the hypertrophies in left or right atrium or ventricle or doule atriums or ventricles, the ECG plus VCG method had a high sensibility and accuracy.For the hypertrophies in right atrium and double atriums,the only ECG method had the same sensibility with the ECG plus VCG method.For the righ ventricle, the only VCG method had the same sensibility with the ECG plus VCG method.For the specificity, the three methods almost had the same value.ECG plus VCG method combining the clinical material could improve the acuracy in the diagnosis of atrial and ventricular hypertrophies.

The stress and stability analysis of arch dam and abutment are the main task of traditional arch dam design. Nowadays there are two kinds of analysis method to use. One method is the arch-cantilever load-distribution method, in which the arch dam stress and abutment thrust are calculated, while the stability of abutment is evaluated by rigid body method or other method. The other is FEM method, which evaluates the arch dam stress and stability of abutment at the same time.

作为拱坝常规设计的主要任务—坝身和坝肩的应力和稳定分析，当今大体有两套体系可用：①用拱梁分载法分析坝身应力和坝肩推力，结合刚体法或其他方法进行坝肩稳定审核；②用有限元法对坝身应力和坝肩稳定同时进行审核。

Authors designed four mixtures of dense-graded asphalt stabilized macadam base with the method recommended by Technical Specifications for Construction of Highway Asphalt Pavement, Superpave design method, coarse aggregate voids filling method and Bailey method separately, and determined the pavement performances of asphalt stabilized macadam base mixture under the optimal oil-stone rate which include resistance capacity to vertical deformation and fatigue. Then, four design methods were compared and appraised. Based on the above study, a new asphalt-stabilized macadam base mixture gradation design method-five control sieve design method was put forward.

There are two modeling methods used in this research area, that is analytical method and numerical method. Analytical method can be used to analyze the sound pressure within enclosures, and to analyze the control mechanisms theoretically, however it can be used for regular cuboids only. Numerical modeling method can manage enclosures with arbitrary boundaries, nevertheless, the results obtained using this method are dispersed sound pressure. It is hard to conduct real time control with this method. The two modeling methods have their own inherent defects.

对于封闭空间的结构声辐射，目前有解析建模和数值建模两种建模方法，解析建模方法可以从理论上对系统进行分析，探讨消声机理，但它只适用于长方体等规则封闭空间；数值建模方法不受空间边界形状的限制，得到的是空间声压的离散结果，难以用于实时控制，两种方法都存在着局限性。
