The integral weight of the framework is less; besides, the framework can meet the design requirements on the use intensity and rigidity.
构架整体的重量较小，而且能够满足使用强度和刚性的设计要求。
Urban land use intensity was descending sharply from the east, the middle to the west part of China, in which Beijing and Shanghai were the tiptop and Gansu was the lowest;
东、中、西部地区城市土地利用集约程度存在明显的递减趋势，其中上海市、北京市最高，甘肃省最低；
The results showed that in this region, soil erosion intensity was highly related to land use intensity, indicating that land use intensity was the main driving force of soil erosion.
结果表明，陕北黄土高原土壤侵蚀强度和土地利用强度呈高度正相关，说明土地利用强度是导致陕北黄土高原本区域土壤侵蚀的重要驱动力。
