研究沙粒两种起动关系是深入认识沙粒两种起动效能的继续和发展。文章分析了沙粒两种起动的不同性质 ,首次把流体起动界定为风蚀性起动 ,把跃移质冲击起动界定为置换性起动。认为流体起动具有主动分异性 ,而冲击起动只有随机分异性。根据这些特性对沙粒两种起动效能和沙粒连续移动提出了新义。认为沙粒跃移具有双重性 ,跃移质有其冲击地表的一面 ,也有其大量耗能的一面。沙粒两种起动具有兴衰与共的不可分割关系。地表风蚀是沙粒两种起动优势互补相互促进的结果 ;而地表堆积有时是跃移质耗能过多引起两种起动互相制约的结果。通过多方论证 ,将沙粒两种起动效能之比由传统的 19∶1,初步改为 4∶1乃至 3∶1。
Studying the relationship between the two kinds of sand grains is to further understand the continuation and development of two kinds of sand grains. In this paper, the different properties of two kinds of sand grains are analyzed. For the first time, fluid start is defined as wind erosion and start of impact shock initiation is defined as replacement start. It is considered that fluid starting has active divergence, while impact starting has only random differentiation. Based on these characteristics, two starting functions of sand grains and the continuous movement of sand are proposed. It is considered that the leap of sand has duality, and the leaping mass has its impact on the surface of the earth, as well as its large energy consumption side. Grit two kinds of starting with the rise and fall of the indivisible relationship. Surface wind erosion is the result of the mutual promotion of two complementary advantages of sand grains. The surface accumulation is sometimes the result of two kinds of starting-up and mutual restraint caused by the excess energy and energy of transition. Through multiple proofs, the ratio of the two starting performances of sand grains was changed from the traditional 19: 1 to 4: 1 or even 3: 1.
