With the help of dynamic mechanical thermal analysis, differential thermal analysis, analysis of curing behaviors and swelling test, the change of structure during the vulcanization of ebonite was analyzed. It is found that the chemical cross-linking in the ebonite trended to descend with degree of vulcanization, while the modification effects of polar groupings on the carbon backbone gradually increased, which dominated its physical and mechanical properties.

通过考察硫化时间对于硬质橡胶结构与性能的影响，结合DMTA、DSC、硫化特性分析、溶胀分析等方法，分析了硬质橡胶的硫化过程中结构的变化，认为在硫化过程中，随着硫化的进行，硬质橡胶中的化学交联作用有下降趋势，极性基团对于碳骨架的改性作用逐渐增加，并对硬质橡胶的物理机械性能起主要决定作用。

During the auto-control mixing,the parameters of the mixing process,such as rotor speed,filling factor,ram pressure and mix temperature have effect on the mix quality;and the effect of some parameters can be decreased by using instantaneous power control.

瞬时功率控制实质上是对混炼物料粘度的控制。1 瞬时功率控制分析粒状填料能否均匀分散在橡胶中虽然与填料粒子的大小、形状和表面状态有很大关系，但起决定作用的仍然是橡胶的粘度。橡胶粘度太大或太小对粒状填料在橡胶中的分散都不利。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
