查询词典 beach cusp

Firstly, based on the force acting on a single-particle, establish a discriminant formula of the sand threshold, and prove that the sand threshold belongs to the cusp catastrophe. Then establish the basic equation of the cusp catastrophe using coordinate transformation and catastrophe theory. Finally, while particle Reynold number and equivalend diameter are the state variables and Shields parameter is the control variables, we can obtain the model of cusp catastrophe of sand threshold, putting those variables into the basic equations of the cusp catastrophe. The model is derived from the mathematics, which has a certain mathematical theory foundation.

员工们总是很友好，很用心，真遗憾，酒店没有在海滩上，因为路上有点吵，但是到海滩的班车服务很不错，房间也很棒，他们的私人海滩区有着非常好的双人太阳床，吊床，四张大海报和豆袋，毫无疑问是很棒的素林海滩上最好的。

The beach body of Lower Triassic Feixianguan Formation in northwestern Sichuan can be divided into platform marginal oolitic beach and intraplatform point beach. The water is relatively deeper at the forming of most of platform marginal oolitic beach which is not transformed by the diagenesis of fresh water and mixed water and has poor reservoir properties. However, a part of oolitic beach formed under shallow water environment, and it is transformed by the diagenesis of fresh water and mixed water and well dolomitized, which can form excellent reservoir.

川西北下三叠统飞仙关组滩体分为台地边缘鲕粒滩和台地内点滩2种类型，多数台地边缘鲕粒滩形成时水体相对较深，未经大气淡水和混合水的成岩改造，储集性能较差，局部鲕粒滩形成时水体较浅，在经过大气淡水和混合水的成岩作用改造后，白云石化好，可形成储集性能极好的储集体；台地内点滩白云石化较好，储集性能也较好，但分布狭窄，厚度较薄，无规律可寻。
