Motibity changed by gear-box in direction and rotate speed is transferred to the blade axis on the right side to drive the blade axis. blade axis'parameter, blade assembling frame and blade assembling means are ascertained. The load and movement of the blade axis are analyzed. And the best blade rotate speed is ascertained. According to the request of no-tillage soil, the appropriate furrow openers are chosen. They are staggered and assembled in two rows .According to the sliding cutting request, the crucial parts of the anti-blocking——the sliding cutting blade, its edge curve is analyzed and designed in principle. The academic curve function is gotten. Combined with working practice and technics request, the blade's figuration parameter is designed, 65Mn is chosen as the material for blades. The working load is analyzed. And the intension of the sliding cutting is analyzed and checked with ANSYS software. At last, the spring rack of the suppress wheal is analyzed in principle. The theory and parameter of designing the spring rack of the suppress wheal. Experiment indicated that the anti-blocking capability of this anti-blocking equipment was excellent.

The thermobaric explosive which is similar to PBXs is the new generation of FAE. By analyzing the PBX theory, the F rubber, D ruber and H ruber were chosen as binders, and the calcium stearate, ceresin and graphite were chosen as desensitizing agents. One kind of binders and two kinds of desensitizing agents were selected to form a system for coating the thermobaric explosive. Then their shaping performance and the mechanical sensitivity were compared.

The 352 valid samples were analyzed by SPSS. The results showed there was no distinct corresponding relationship between the product attributes and reaction time. The different key attributes from questionnaire importance rating and the shortest reaction time standards were used to regressively analyze the results of customers' overall rating (such as overall satisfaction,objective quality, recommend intention).The results indicated that the coefficiency of regression of the special attributes chosen from reaction time to overall rating was distinct, while the coefficiency of the special attributes chosen from importance rating to overall rating was not. The main conclusions are: 1. Regarded attributes can be obtained by the reaction time of brand performance rating.
