八字形双圆盘分草装置在开沟器前安装两个成&八字形&布置的凹面圆盘，对粉碎后的玉米秸秆有很强的分草排堵作用。

For bulk cylinder-forming diblock copolymers, a series of novel structures such as helices and stacked toroids are identified which cannot form in bulk block copolymers.

对体相形成柱状相的双嵌段共聚物，在不同孔径的孔内我们观察到了一系列体相不存在的螺旋和层叠圆环等新奇结构。

This is a new kind of photoinduced phenomenon and it is a one-photon process.(2)A bipolaron is split into two polarons by photoexcitation.This photoinduced splitting converts a charge carrier into two spin carriers.(3)When the hopping effect is included, the energy of a soliton-antisoliton pair can be lower than that of single polaron in conducting polymers with degenerate ground state.

这是一种新的单光子过程光致现象；（2）通过光激发，一个双极化子可以分裂成两个极化子，这种光致分裂效应将一个荷电载流子转换为两个自旋载流子；（3）对具有简并基态的导电聚合物，如果计及跃变常数的变化这一效应，孤子-反孤子对的能量可以低于单个极化子的能量。

For the bulk cylinder-forming diblock copolymers, the cross sections of the confining channels also include rectangules, regular hexagons and regular octagons besides the above mentioned shapes.
