According to the studied results at present, the studied objects are mainly thin plate and beam about sound radiation mode, a method computed sound radiation mode of complex structure is presented in this dissertation, according to the results of the previous two chapter, a theoretical method to solve acoustical radiation mode and acoustical radiation efficiency of complex structure by boundary element method and acoustical radiation theory is posed, the acoustical radiation power is expressed as a Hermitian quadratic form, while the radiation modes is determined by general eigenvalue decomposing, and then the radiation efficiency is computed via the orthodoxy of radiation modes with regard to impedance matrix and average velocity matrix; lastly, the validity of the method is proved by pulsating sphere and radiating cube with analytical results. According to results of the form three chapter, the structure sound radiation sensitivity is studied in detail, the sound radiation power of structure can be expressed as positive Hermitian quadratic form, the sound radiation sensitivity can be expressed as two parts by partial differential with respect to design variable, which are sensitivity of boundary velocity and impedance matrix, combined with the theory of FEM and BEM, the structure sound radiation can be translated to the analysis of structure dynamic sensitivity and impedance matrix sensitivity. The theory posted in this dissertation is tested by the FEM software ANSYS and the software AAS programmed by author.

在前几章的基础上，通过结构声辐射的模态理论对结构的声辐射的机理进行了深入地探讨，针对目前声辐射模态的研究对象主要是简单的板和梁类结构，提出了一种计算复杂结构声辐射模态的方法，利用前两章研究所得的结论，将边界元方法与广义特征值的理论结合起来研究了复杂结构的声辐射模态与声辐射效率，先将结构的声辐射功率表示为一个正定的厄米特二(来源：ABb7C论文0909网www.abclunwen.com)次型，运用广义特征值分解求解了复杂结构的声辐射模态，然后利用声辐射模态关于阻抗矩阵与均方速度耦合矩阵的正交性，求解了复杂结构的声辐射效率，最后用具有解析解的脉动球与辐射立方体验证了该方法的有效性。

Since 1950s,a series of such new economic phenomena as"Mystery of Modem Economic Growth"and"Mystery of Leontief,Wassily"have posed great challenge to the traditional theories,particularly such basic economic hypothesis as Capital Homogeny and Work Force Homogeny.

二十世纪五十年代以来，一系列新的经济现象，如"现代经济增长之谜"、"里昂惕夫之谜"等对传统经济理论，尤其是资本同质、劳动力同质等经济学基本假设提出了严峻挑战。

Hypertonia interferes with selective motor control and performance of activities in children with spastic cerebral palsy. At present, most therapists use traditional therapeutic techniques such as neurodevelopmental treatment or other approaches to handle the problems posed by cerebral palsy but the results are not very good.

过高的肌肉张力常会使得痉挛型脑性麻痹儿童在动作上有许多的限制，造成日常活动的表现不佳，目前治疗师多以传统治疗手法来处理，但疗效有限。

Be- cause of noisy data,the linearization of nonlinear problems,and in- adequate parameterization of the model,migration velocity analysis is thought to be ill-posed and ill-conditioned.

但由于非线性问题的线性化、噪声及不具物理意义的模型参数化假设，偏移速度分析是不适定和病态的。

In the morning class at Jubilee, a student posed a question ,"Can God anoints a person without impartation from a man of God?"

在Jubilee 的早堂，一位学生问了一个问题，"神是否能在不透过祂仆人的传递下，亲自膏抹一个人？"

Because they are trained to think of financial markets as efficient, most economists weren't primed to spot the dangers posed by lax mortgage lending, overleveraged financial institutions, and impenetrably complex derivatives.
