Note that the path must be a closed loop - that is, the first point of the first Edge object in the path must have the same location as the last point of the last Edge object.

注意，路径必须是一个闭环—也就是说，路径中第一个Edge对象的第一个点必须与最后一个Edge对象的最后一个点的位置相同。

The tectonic location, stress condition, sedimentary environment, sediment characteristic and wall rock condition are the elementary factors considered in loop bedding study.

研究环状层理必须综合考虑构造位置、应力条件、沉积环境，沉积特征、围岩条件等因素的影响和控制作用。

The solid flow behavior in liquid-solid loop reactor was studied with draft tubes, and nozzles of different size and with different nozzle location.

在不同的导流筒直径、喷嘴直径和喷嘴位置对液固环流反应器中固体流动行为进行考察。
