The fundamental solutions for an infinite plate with an elliptical inclusion under uniaxial tensile stress are given by using the muskhelishvili " complex potentials and progression method 运用muskhelishvili复势理论，采用级数法得到了单向拉伸状态下，含有椭圆夹杂的均匀无限大平板的基本解。
Secondly , the writer carried out the calculation on prestressed concrete slabs with openings by yield line theory and got the changes of limit load of openings of different size , different place 然后，笔者采用屈服线理论对预应力混凝土开孔平板的极限承载力进行计算，得出不同开孔参数对应的极限承载力。
The wkb method is used to calculate the amount of reflection coefficient of a plane wave normally ( or obliquely ) incident on a conductive plane covered with inhomogeneous unmagnetized plasmas 用wkb方法给出了垂直入射、斜入射情况下，非磁化不均匀等离子体密度覆盖导体平板的等离子体对不同频率电磁波的反射系数。
The mechanical model of 3d woven composite is set up to analyze it ’ s mechanical properties , and was validated by the stretch mechanics performance tests of the 3d woven composites have been made 本文利用建立的细观力学模型分析了三维机织复合材料的弹性性能,并通过三维机织复合材料平板的常温拉伸试验进行了验证。

Finally , the writer brought forward reasonable advice to engineering design of prestressed slabs with opening and all these advice is very important to the engineering practice of structures with openings 最后，笔者利用分析出来的结果，对预应力混凝土开孔平板的工程设计提出设计建议，其研究成果对开孔结构的工程实践具有重要的参考价值。
This paper first discusses the cause of crack formation and crack mechanism of high performance concrete . then carries out crack tests of three groups of concrete slabs using aggregate type , sand rate and dosage of fly ash as design parameter 本文初步探讨了泵送高流态混凝土的裂缝成因和开裂机理，并分别以骨料品种、砂率以及粉煤灰掺量为设计参数进行了三组配合比混凝土平板的抗裂试验。
Piezoelectric elements were bonded on the plate as actuators and the input voltage of each actuator was determined by the velocity of its position and volume velocity of the plate was made zero , through which the sound radiation from the plate could be controlled 在简支薄板表面粘贴压电片作为致动器，根据所处位置的速度确定输入控制电压，并使平板的体积速度为零，从而达到控制声辐射的目的。
Narrative - wise , as i mentioned above , the love plot between takumi jay chou and natsuki anne suzuki is rather weak , while the two father and son relationships , that is , takumi bunta anthony wong and itsuki yuichi kenny bee , are way more impressive and funny 剧情方面则正如上述友情和亲情胜过爱情尤其拓海和父亲及阿木和父亲两段最好描写简洁有力大大胜过拓海和夏树那段陈套平板的天真puppy love 。
Secondly , the basic methods for parameter identification and the identifiability of parameter identification are dissertated . through the example of the problem of heat emission in one - dimensional infinite slab , the identifiability of thermodynamic parameter of concrete is proved theoretically 论述了参数辨识的基本方法和参数可辨识性的条件，以一维无限大平板的散热问题为例，从理论上论证了混凝土热力学参数可辨识性。
