In this work, by the use of several physico-chemical complementary methods for the characterization of soil (diffraction of x-rays, chemical analysis, density, cationic exchange capacity, specific sur faces, m?ssbauer, granulometry, etc.), the smectite of the three clayey localities of benin (Gbédji-Kotovi, Massi-Sèhouè and Zogbodomey) was notably studied. Thus, these three sites principally contain principally smectite, kaolinite and quartz in variable proportion. This smectite is a beidellite. Its chemical formula is proposed. The specific surfaces and the cationic exchange capacity of the samples are determined. For these samples, the fraction lower than 2 μm is practically beidellitic for Gbédji-Kotovi and Massi-Sèhouè (more than 82% of beidellite) and practically kaolinitic (70% of kaolinite) for Zogbodomey. So, used as additive food to ruminant, the clay of Gbédji-Kotovi and Massi-Sèhouè will induce an enteric reduction of methane more than clay of Zogbodomey.

用旋转式粘度计对润滑脂的研完表明:它的性能类似于宾汉塑性体,流动性可用数学模型τ=τ+ηD 来描述。即剪应力由初始屈服应力和粘度效应组成。此外,受剪区的塑性润滑膜可以采用牛顿流体润滑使用的方法,引入外观粘度:τ=η~*D。研究表明:正确设计和选择脂润滑系统是很重要的,研究结果还为脂润滑的滑动轴承提供了设计和计算的依据。
