The amplitude of the surface velocity of the panel and the acoustic pressure on the porous surface are reduced largely in the vicinity of structural resonances due to the additional radiation damping and visco-thermal absorption phenomenon in the porous layer.

请注意振膜表面速度分布的两种极端情况。一种极端情况产生在作活塞运动的刚性表面中，此时整个表面的振幅和相位是处处相等的。

Taking the effect of non-radial bearings in the beam-ends into consideration, the rigid-crossbeam method was used to calculate the load lateral distribution of curved beam bridge with non-radial bearings as to get more accurate results.

用刚性横梁法计算非径向支承弯梁桥的荷载横向分布，在计算单梁挠度时考虑了主梁梁端非径向支承的影响，得到了更为精确的结果，根据影响参数，编制了相应的表格，方便工程设计人员查用。

In this paper, with polygon line hypothesis of τ-u relationship of horizontal restrained condition of foundation, and winker hypothesis of vertical restrained condition of foundation, a new analytical method to calculate thermal stress of mass concrete structure on foundation with biconditional restriction is presented.

1概 述在现有的地基上砼板温度应力的计算方法中，多考虑地基的单向非刚性约束及假定板全截面均匀受力进行有关的推导与分析。

To overcome the disadvantages of the cable dome, this paper proposed a new spatial structure composed of cable dome and single-layer lattice shell. The composite structure makes full use of mechanical characteristic of cable dome and easily laying rigid roof board of single-layer lattice shell.

为了解决这些问题，本文提出了一种由索穹顶与单层网壳组合的新型空间结构形式，该结构可充分利用轻型、高效、通过预应力成型的索穹顶结构特性，又可发挥单层网壳便于铺设刚性屋面板的优势。

This process takes more time in the New Keynesian model than in the real business cycle model because of rigidities in wages and prices.

由于工资和价格的刚性，新凯恩斯模型中此过程所花费的时间要多于真实经济周期模型中花费的时间。

The analysis shows that when λ is amended the resolution of single group delayed neutron model is approximately equal to the numerical solution of six groups delayed neutron model, which meets engineering accuracy.

结果表明：采用修正后的单组解析方法计算阶跃正反应性输入的中子密度响应，计算结果与六组的接近，满足工程计算精度要求，同时计算简便，避免了刚性问题，可以实现快速计算。

Atechnique of low-profile fixation using obliquely oriented screws from the radial head into the shaft has been developed to avoid distal dissection of the soft tissues and placement of hardware in an already-constrained area adjacent to the annular ligament and lateral ligamentous structures.
