研究表明,在自然状态下,由于地表土壤的粒子尺度分布特征、植被覆盖度及地表土壤水分含量等下垫面特征不同,绿洲地表风蚀起沙的临界摩擦速度要大于戈壁地表,其垂直尘粒通量(风蚀起沙率)比戈壁地表小将近一个数量级;但考虑人为的翻耕作用时,绿洲地表风蚀起沙的临界摩擦速度可能会减小一半以上,其垂直尘粒通量也将增加大约一个数量级,甚至比戈壁地表还要大。

补充资料:油封
分子式:
CAS号:

性质:系旋转轴橡胶密封的主要品种,习惯上常简称为油封。具有柔性唇,通常结合有一个或两个金属骨架作为支撑,以提高油封的刚度,靠密封唇施加于轴表面的径向压力来防止流体泄漏。为保持一个恒定的径向压力,在其唇部常加一个箍紧弹簧。按其运动状态可分为低速油封和高速油封;按主体结构可分为有骨架型、无骨架型和复合型,其中骨架油封又有外骨架和内骨架、有弹簧和无弹簧、带副唇和不带副唇之分。制作油封的胶料有丁腈橡胶、氟橡胶、硅橡胶、丙烯酸酯橡胶及硅氟橡胶等。本产品广泛用于各种机械设备中,被密封介质主要为各种矿物润滑油和液压油等。
