The results showed that diploid and tetraploid had higher root activity, flagleaf soluble protein content, SOD and CAT activity before anthesis. However, the rootactivity, flag leaf soluble protein content, SOD and CAT activity of diploid and tetraploiddeclined more quickly and became lower than those of hexaploid species from 15 days afteranthesis. While MDA content increased more quickly and became higher than those ofhexaploid species from 5 days after anthesis. Correlation analysis showed that delaying the flag leaf senescence can promoted transfer of nitrogen and dry matter, increasedaccumulation of nitrogen and dry matter after anthesis, enhanced grain and protein yield.

研究结果表明，胶质含量超过20mg／100mL时，随胶质含量的增加动力性下降。120h道路模拟试验证明，长期使用高胶质汽油会造成进气管、进气道和进气门背部生成大量沥青状沉积物，严重时影响汽油机的正常工作。

Under two levels of earing fertilization (N0 and N2), compared with 25℃ treatment, heat stress (35℃) accelerated the grain filling and resulted in less grain weight, and also reduced the two glutelin subunits content of both fertilization treatments 12.1% and 5.7% respectively, and reduced the prolamin content of them 6.7% and 4.9% respectively. Simultaneously, the polypeptides above 57 kD was increased 18.8% and 11.7% respectively, and grain crude protein content was also increased 0.56% and 0.35% respectively.

Using DC and AC poling methods, three groups of polarized PZT/P 70/30composites have been prepared by poling only the ceramic phase(1), both ceramic and polymerphases in the same(2) and opposite(3) directions. Piezoelectric coefficients of group 1 compositesincrease as the PZT content increasing, while for group 2 composites, the piezoelectric coefficientschange the sign with increasing PZT content because piezoelectricity of copolymer is increasinglycompensated by that of PZT, and PZT content for zero-〓 isn't that for zero-〓. The experimentdata of both group 1 and 2 composites agree well with EMT-Shin model.

对复合材料的压电性能：只极化PZT粒子相的复合材料的压电系数随陶瓷分数的增大而增大，PZT粒子相与共聚物基体同向极化的复合材料的压电系数由于两相效应的部分抵消，随陶瓷含量的增大，发生符号的改变，且〓和〓零点不重合，它们与EMT-Shin模型都符合较好；而两相反向极化的复合材料的压电系数由于AC反向极化会导致陶瓷相极化程度的下降，导致实验值和理论预期偏差较大，尤其在PZT粒子高含量区。
