2中国台风暴雨的雨季是5至11月，其中7至9月是高峰期；台风暴雨频次存在很强的年际振荡和年代际的起伏；长期来看，频次和强度都呈现出上升的趋势，但在统计上是不显著的；另外，暴雨的频次和强度等存在一些准周期，但同样是不显著的。

These results indicated that the seedlings of Vallisneria natans were adapted to low intensity which ranged from 7.1% to 43.3% of natural light intensity.

这表明苦草幼苗有一定的低光适应能力，光强范围大约是7.1%~43.3%，为在浑浊水体中恢复、重建苦草种群提供了一定的实验依据。

The apparent permeability coefficient of FITC-albumin was calculated using the equation Pa=(1/△If)〓(r/2), where,△If is the initial step increase in fluorescent intensity,〓 is the initial rate of gradual increase in intensity as solutes diffuse out of the vessel into the extravascular space, and r is the venular radius.

荧光标记白蛋白在微血管的通透系数则通过公式Pa=(1／△If〓(r／2)，其中△If代表了初始荧光标记白蛋白浓度，〓则是荧光蛋白渗出管壁的速度，而r是血管半径。

From the middle to the south in the research area, the compaction, the pressure dissolves the function and the structure disruption intensity enlarges gradually, the silicon nature agglutinates the content to increase gradually, and the corrosion function intensity reduces gradually. The diagenesis stage is carried on according to the division standards of secondary enlargement degree, pellet contact type as well as porosity type, the authigenic mineral characteristic, agglutinates, the diagenesis of Xujiahe formation is thoughted degree to be intense, which already entered the late diagenesis stage A sub-stage.

从研究区中部向南部，压实、压溶作用和构造破裂作用的强度逐渐加大，硅质胶结物含量逐渐增多，溶蚀作用强度逐渐降低；并根据成岩作用类型、自生矿物特征、胶结物的次生加大程度、颗粒接触类型以及孔隙类型等划分标准，对须家河组进行了成岩作用阶段划分，认为研究区须家河组成岩作用程度强烈，已经进入晚成岩作用阶段A亚期。
