查询词典 sweep

Chapter 2 establishes a helicoid model of the 3D curved shock surface, which is a fundamental means for investigating the sweep of the 3D shock surface In chapter 3, the first step is to make definitions and detail concepts about various viewpoints of shock surface sweep. Secondly, those sweep angles of the 3D shock are calculated. After that, with the aid of the helicoid model, two general structure similarity variables are derived which are independent of any model, and their importance in shock structure investigations is discussed.

The contact mode AFM could be used to "sweep" the slipcover and expose the mark. As an example, in situ observation of the bovine serum albumin adsorption film on highly ordered pyrolytic graphite was described. When the marks, atomic steps on HOPG, were covered by BSA molecules, contact mode AFM could "sweep" the BSA molecules away.
