3.Chapter 1 is a summarization of click-wrap contract, which includes the uniform Chinese translation of click-wrap contract, the definition of click-wrap contract and its basic characteristics on the basis of the analysis and the comparison of click-wrap contract with some other relative contracts, such as E-contracts, shrink-wrap contracts and traditional standard contracts.
4.This paper provides the general equations of the theoretical contour line and the actual contour line of roller translation follower and roller oscillating follower disc cam in the polar coordinates system and the rectangular coordinates system,respectively.The equations are not only fit for the different layouts of the relative position of follower and cam,but also fit for the different types of cam contour.
