Triple-screw extrusive industrial equipment is a new technology coming out in recent years. Although its extrusive characteristics such as energy-consuming, disgregation, exhausting and so on have been tested very well, the flow pattern, blending and mixing mechanisms and the shearing effect of polymer melt in triple-screw are waiting for our in-depth researches.

由于三螺杆挤出工业装备是这两年刚刚问世的新技术，对其挤出特性，如能耗、分散、排气等作了很好的研究测试，然而，由于是一项问世不久的新技术，对三螺杆挤出机中物料的流动形态、混合混炼机理和剪切作用等方面有待深入研究。

The utility model comprises a pair of two-section rod, a pair of three-section rod, the dismountable gun head, cutter head, sword head and fork head, etc. Mutual connected and dismountable screw threads are arranged between every two sections of the rod, and the screw threads on the rod end are also arranged on the attachments such as a gun head, a cutter head, a sword head and a fork head.

该实用新型包括一个对两节杆，一对三节棒， dismountable炮头，刀头，剑头和叉头，等互相连接，并dismountable螺纹均安排之间每两节的棒，以及螺纹对杆端也安排实习，例如一炮头，刀头，剑头和一个叉子头。

Herbacium were isobilateral leaves, and those of G. hirsutum and C. barbadense were dorsiventral leaves. The reciprocal F〓 of cross G. arboreum×G. herbacium were also isobilateral leaves, while reciprocal F〓 cross of G. hirsutum×G. barbadense were also dorsiventral leaves. The quadrispecific hybrids F〓 were isobilateral leaves, regardless of their cytoplasms. The structures of the leaf stalks and the stems were analogous to each other among the four cultivated cotton species except their diameters varied with species.

四个栽培棉种及其种间杂种F〓的形态学和细胞遗传学观察四个栽培棉种的植株、叶片、茎杆以及花器等器官都有明显的差异；叶片、茎杆以及叶柄的横切面结构观察结果表明，两个二倍体栽培棉种的叶片横切面构造为等面叶，两个四倍体栽培棉种却均为背腹叶；F〓正反交的叶片也为等面叶，F〓正反交F〓仍为背腹叶，而它们的四元杂交种均为等面叶；四个栽培棉种的叶柄和茎的横切面结构基本一致，只是直径形状和和维管束多少的不同，四元杂种的叶柄和茎的横切面结构的差异不明显。
