There were 8 groups and each groups had 8 cows in the experiment.groups A was the positive group, be feeded basic dietary and in the normal environment; groups B was basic dietary and in the improved environment ; Group C was feeded with basic dietary and NaHCO_3(120g/d/head) and Mg0(50g/d/head) and KCl(180g/d/head), in the environment with no spray and no wind; Group I is feeded with basic dietary and NaHCO_3 (120g/d/head) and MgO(50g/d/head) and KC1 (180g/d/head) and in the another environment with spray and wind; Group E was feeded,with basic dietary and traditional druggery additive in the environment with no spray and no wind; Group F was feeded with basic dietary and traditional druggery additive in the environment with spray and wind;Group G was feeded with basic dietary and NaHCO_3 (120g/d/head) and MgO(50g/d/head) and KCl (180g/d/head) and traditional druggery additive in the environment with no spray and wind; Group H was feeded with basic dietary and NaHCO_3( 120g/d/head ) and Mg0(50g/d/head) and KCl(180g/d/head) and traditional druggery additive in the environment with spray and wind.

试验分8个处理，每个处理8头奶牛，A处理为对照组，喂以基础日粮，处于常规环境(未喷雾，未机械吹风，下同)，B组为喂以基础日粮，处于改善环境：C组为基础日粮+NaHCO_3(120克/头。日)+MgO(50克/头。日)+KCl(180克/头。日)，处于常规环境：D组为基础日粮+NaHCO_3(120克/头。日)+MgO(50克/头。日)+KCl(180克/头。日)，处于改善环境；E组为基础日粮+中草药添加剂组，处于常规环境；F组为基础日粮+中草药添加剂组，处于改善环境；G组为基础日粮+NaHCO_3(120克/头。日)+MgO(50克/头。日)+KCl(180克/头。日)+中草药添加剂组，处于常规环境；H组为基础日粮+NaHCO_3(120克/头。日)+MgO(50克/头。日)+KCl(180克/头。日)+中草药添加剂组，处于改善环境。

In addition to electrostatic ion series fan, wind machine, wind Tsui, wind wand, wind Copper Rods, wind screens, copper, wind serpent, wind drum, surface resistance tester, voltage tester, wrist strap tester, wrist / leg band tester, and so on, may provide a good addition to the electrostatic effect of space and surface electrostatic field has a very good and the elimination of functions.

The results showed that soil wind erosion was the near-surface wind-sand activity. The sediment particle saltates mainly in 7.5-43.5 cm. Wind sediment amount decreased along height, which correlate well with power function, exponent function and logarithm function. The sediment particle composition was influenced strongly by wind erosion intensity and topsoil characteristics. However, the regularity of sediment composition was distinct in a definite paticle size in different heights. Wind erosion amount increases with wind speed exponentially, which was influenced by times that the wind does.

结果表明：阴山北麓农牧交错带土壤风蚀是一种近地表的风沙运动，风蚀物跃移颗粒体主要集中在7.5～43.5 cm高度，风蚀物含量沿高度呈一递减函数，对幂函数、指数函数和对数函数均具有较好的相关性；风蚀物颗粒组成与风蚀强度和地表状况关系密切；风蚀物颗粒组成以某一粒径范围、某一高度为界随高度的变化而表现出明显的规律性；风蚀量沿高度的变化与风力作用时间有关，风蚀量随风速的增大呈指数增加。

head wind：逆风

纯方帆的问题在于,尽管它在顺风(Before the Wind)行驶时能提供很大推进力,但在逆风(Head Wind)时却很笨拙而效率低下. 为了在迎风时控制风帆,保证风帆帆缘(leech)朝前,在帆缘上装有帆缘索(bowlines),帆脚索连接到从艏楼伸出的艏斜桅上.
