Finally, the grafting polymerization of textile materials initiated by microwave low temperature plasma was conducted. Knitted cotton fabric was grafted by AMPS first, then knitted cotton and terylene/cotton fabrics were grafted with AMPS/NIPA dualistic monomers respectively. By means of grafting polymerization, the P dualisticintelligent hydrogel was added to textile.The influences of the factors on add-on, such as treatment time and power of plasma, concentrations of crosslinking agent and total monomers, proportion of AMPS, polymerizing temperature and time etc, was studied fully. The optimal conditions of grafting polymerization initiated by microwave low temperature plasma were determined by orthogonal design, variance analysis and mathematical statistics method so as to analyze the main influencing factors. Then swelling/deswelling kinetics, temperature-sensitivity and pH-sensitivity of grafted textile were studied. The performance indexes of hydrostatic pressure, moisture permeability and bursting strength of the knitted cotton and terylene/cotton fabrics before and after grafting were compared and evaluated synthetically.

Selection for high specific strength had no negative effect on the obtention of high yield genotype. The correlation among fiber length, strength and micronaire of cotton for spinning high value yarn were still inconsistent. Further improvement is needed.

以上结果说明高产纺高支纱陆地棉首先应具有结铃性强、成铃多的基本性状，同时要兼顾衣分；选择高强纤维不会影响高产基因型的获得；纺高支纱陆地棉存在纤维品质不配套的问题，应进一步改良。

In this study, we developed the plant regeneration system of island cotton Gossypium barbadense L.

本研究通过诱导海岛棉下胚轴的体细胞胚胎发生建立了海岛棉的植株再生体系；并以新海16胚性愈伤组织为受体，通过农杆菌介导法进行了SATI基因的遗传转化，获得了转基因再生植株。

Moreover, the obligative parthenogenesis individuals had been found in the cucumber specialized aphids, but not in the cotton specialized aphids.

瓜型棉蚜在诱导条件下产生无翅孤雌蚜的比率显著高于棉花型棉蚜，并且发现有不产生有性世代的营专性孤雌生殖个体，而在棉花型棉蚜中没有发现。

Firstly, take polyester short fiber, nylon short fiber and cotton powder short fiber for examples, a study was made on the influence of content and kind of short fibers on physical and heat aging properties of short fiber-CR composites. The experiment results showed that the rigidity of the composite increased as the content of the fiber increased, and the tear strength, the modulus at 20% in L direction also increased; thereinto, the reinforcement effect of nylon short fiber was the best, and the cotton powder short fiber was the worst.

第一，以聚酯短纤维、尼龙短纤维、棉粉短纤维为例，研究了短纤维的用量和种类对短纤维-氯丁橡胶复合材料力学性能、耐热性能及其溶胀性能的影响；结果表明，随纤维含量的增加，短纤维-CR复合材料的硬度不断增大；在L向拉伸时，撕裂强度、定伸应力不断提高；尼龙短纤维的补强效果优于其它两种，棉粉短纤维的最差；随纤维含量增加，短纤维-CR复合材料整体耐热老化性得到了极大提高，其中尼龙短纤维-CR复合材料的耐热老化性明显优于其它两种；随纤维含量的增加，短纤维—CR复合材料的耐溶胀性能明显提高；短纤维-CR复合材料的性能呈现明显的各向异性。
