Six kinds of superior Leguminosae and grasses including Sweet pea , partridge pea , Utah sweet vetch , meadow brome , yellow bluestem and cambar bluegrass are introduced from the Western and Middle parts of USA with similar climate to the Loess Plateau according to the theory of similarity of climate. The experiments are focused on adaptability, regularity of growth and development, eco-economic values, and technique and model of cultivation of the introduced plants, following the procedure of primary test, regional test and production test.

按照"气候相似论"的观点，选择与黄土高原生态条件较为接近的美国中西部地区，引进了多年生香豌豆、美丽鹧鸪豆、犹他甜苕子、牧场草、黄兰沙梗草、康巴早熟禾等6种优良水土保持草本植物，按照"初选试验—区域性试验—生产性试验"的程序，对引进植物的物候、抗性、生长发育规律、生态经济价值、栽培技术等进行系统研究。

There were four treatments on the hillside: artificial forest with underbrush, artificial forest without underbrush, planting tea bush on contour terrace, barren on contour terrace. The runoff depth, runoff index, water loss, soil erosion and soil organic matter erosion to the 4 treatments during 4 rainfalls were determined by using the Runoff Collector.

试验设计了人工林下地表覆盖、人工林下地表裸露、等高梯田种植茶树和等高梯田裸地对照4个处理，采用自制的径流收集器分别测定了各处理4场降雨的径流深度、径流系数、水土流失量和侵蚀量等指标。

And the calculation method of theresistance modulus has been given by rule and line. The flow state in the pipeline of the densecolloid slurry is carried on numerical value simulation by the software CFD Fluent, which hasbeen grasped. And the critical flow velocity of the dense colloid slurry in the different ratio ofbetween water and earth is obtained by numerical calculations.

通过使用 CFD 软件 Fluent 对稠化胶体泥浆在管道内的流动状态进行了数值模拟，获得了稠化胶体泥浆在胶体流动性实验台管路中流动时的流型，并且通过计算得到了稠化胶体泥浆在不同水土比下的临界流速。
