The results show that the fibers with good dye ability can be obtained from blends containing certain amount of SIPE, which are made by using an appropriate proportion of cationic dyeable polyesters and recycled polyester.

结果表明：以适当比例和种类的CDP与PETRc共混，制得的三单体含量一定的共混纤维，能够实现阳离子染料常压染色；影响CDP/PETRc共混纤维实现常压染色的主要因素是共混纤维的结晶度和玻璃化温度。

The results showed that there was a negative relationship between H2O2 content and CAT activity, thus H2O2 content was low when CAT activity was high. There was a close relationship between H2O2 content and differentiation process. H2O2 could be an important signal transduction factor during bud differentiation. IAA oxidase activity was decreased firstly, and then increased, which affected IAA oxidase and degradation pathway and regulate ratio of cytokinin and auxin. With differentiation process continuing, PPO activity was increased, which could cause browning or vitrifaction of seedling, or even malformation.

研究结果表明，鹅掌楸组培再生过程中，过氧化氢酶活性与H2O2含量变化呈负相关，CAT活性较高时，H2O2含量则较低。H2O2含量与鹅掌楸组培苗分化进程密切相关，H2O2可能作为信号因子在芽分化过程中发挥重要作用；IAA氧化酶活性呈现先下降后增加的变化规律，从而影响IAA氧化降解途径，调控细胞分裂素与生长素含量的比值，影响鹅掌楸芽的再生；PPO活性随培养时间的增加而升高，引起组培苗的褐变或玻璃化，甚至生长畸形。

The storage modulus is increased with the increase of Cf, while the peak temperature of loss factor and the temperature of loss modulus are not changed with the variation of Cf, which means that the reinforcement of chitin fiber has no effect on the motion of molecular segment for PCL.

动态热机械分析表明，复合材料的储能模量随纤维含量的增加而增加，表征玻璃化转变温度的损耗因子松弛峰的峰值温度和损耗模量的温度都不随纤维含量的改变而变化。

In the experiment, three thawing methods, such as washing by water at 40℃, exposing at the room temperature of 25℃, and washing by tap water were used to estimate the effects of thawing methods on the survival rate after cryopreservation. The results showed that the relative survival rate of the calli with proembryos was higher than that of the general calli; and that different thawing methods had the same effect on the survival rate of longan calli by cryopreservation.
