The scattering characteristics of plane acoustic waves by fluid-saturated porous cylinders are studied by using the Biot-Stoll's theory with consideration of loss factors, such as the viscosity of fluid and the nonelastic loss of solid skeleton.

依据Biot-Stoll的流体饱和多孔媒质声传播理论，考虑了流体粘滞和骨架非弹性损耗引起的衰减因素，研究了多孔圆柱体对平面声波的散射特性。

Various factors have contributed to this shift and affected Thailand's traditional and nontraditional incomes.

Methods Rat models of cerebral edema after cardiac arrest were established by water-airproof bottle obturation methods, and CPR was carried out at once.

脑水肿是指脑组织的含液量增多而引起的脑容量增加，它是中枢神经系统受到各种外源性或内源性有害因素刺激时所产生的一种最常见的非特异性反应。

Objective: Obturator hernia is a rare internal hernia but it represents an important cause of intestinal obstruction in elderly women.

It is commonly acknowledged that the thrusting which occurs in the front of orogen is another main factor leading to foreland basin inversion, the strike-slip inversion and oblique inversion.

造山带前缘的逆冲体系作用也是引起前陆盆地反转的主要因素，走滑反转和斜向反转在造山带中也很普遍。

The results showed that the diurnal changes of photosynthesis of S. chinensis in tile overstory took on "double-peak" curve with remarkable midday depression. The midday depression was mainly due to non-stomata1 limitations. On the contrary, the diurnal changes of photosynthesis of S. chinensis in the understory took on "one-peak" curve with low Pn. The maximal Pn was only half of that of S. chinensis in the overstory. The correlation analysis showed that the limiting factor for this low Pn might be light intensity (p=0.001). Compared with its accompanying plants, S. chinensis was in a disadvantaged status in the community with low photosynthetic capacity, water use efficiency, and the ratio of photosynthetic rate to respiration rate.

结果表明：夏蜡梅冠层的光合速率日进程呈"双峰"曲线，有明显的"午休"现象，经分析其"午休"的原因主要是由非气孔因素引起的；林下夏蜡梅则表现为"单峰"曲线，净光合速率较低，最大净光合速率不及冠层的1/2，相关分析结果表明其最重要的影响因子是光合有效辐射(p=0.001)；与其它伴生植物相比，夏蜡梅的日均光合速率、最大光合速率、水分利用效率和光合速率／呼吸速率都明显偏低，在群落竞争中处于不利地位。

The cause of aggregation was because of mass oviposition behaviour of adults.
