In order to study the digestion of fibrous materials ADF and NDF,the alfalfa,ryegrass and their powder mixture were chosen as the substrates,and mixed with the cecum chyme filtrate for fermentation.pH value declined to 6.9 during first three hours fermentation,and then came to be stable.

以苜蓿草粉、黑麦草粉和混合草粉(质量比为1∶1)为底物，接种鹅盲肠食糜滤液进行体外培养。试验结果为：培养液pH值在0~3 h下降到6.9左右，后逐渐趋于稳定；苜蓿草粉ADF、NDF和半纤维素的消失率分别为1.15%，1.18%，-0.19%；黑麦草粉三者的消失率分别为1.45%，9.05%，3.07%；而混合草粉三者的消失率分别为15.72%，13.2%，9.87%。与单一草粉的ADF、NDF和半纤维素的消失率都有显著差异(P.05)。

Under certain conditions, the activation and migration of soil Cd were accelerated by the interaction of Pb and Cd and increased Cd uptake by wetland rice. The organic-bound Cd in rizhosphere decreased by 90%. These phenomena illustrates that the interaction is very important for the transformation of soil Cd fractions. Meanwhile, the interaction distinctly affected the composition of roots secretion and their coordination abilities with heavy metals, causing clear variation to Cd amount in root cortex and middle columniation.

在一定的实验条件下，Pb和Cd的交互作用促进了Cd的活化与迁移，增加了水稻地上部分对Cd的吸收，使根际土有机结合态Cd下降了90%左右，表明交互作用对Cd形态的转化是一个重要的控制因素；同时交互作用对根系分泌物的组成及其与重金属的配位能力有着明显的影响，使Pb、Cd在根系皮层和中柱中Cd的含量有明显变化。

Cyclodextrin linked to the guanidine causes more positive charge localizing at the central Cu cation of {[Cu (H2O)]2}(superscript 3+), which is favorable to catalyze the dismutation reaction.

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。

The results showed that the light seiner had decreased continually with the station in marine fishery declining constantly due to development of single trawlers and drift gill net; fishing vessels became large and fishing ground was pushed to deep water,significant development had been achieved in light-source fittings technology; Decapterus maruadsi was dominant in the catch, the percent of Pneumatophorus japonicus increased and Sardinella aurita fluctuated obviously.

结果表明：由于单拖作业和流刺网作业的发展，灯光围网作业持续萎缩，在海洋渔业中的地位不断下降；渔船大型化，渔场向深水推进，灯源配置及集鱼并灯技术取得重大突破；主要渔获物中蓝圆鲹占绝对优势，鲐鱼所占比例有上升的趋势，金色小沙丁鱼年间波动明显，颌圆鲹则快速减少，竹荚鱼近年来产量快速增长。

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。
