The three factorsaffect the mites and their enemies integrally,in which thecombination of tempetature and leaf moisture are more importantto the populations,more overiaps of the microclimatic niches ofthe two mites are in the later season,and less overlaps in theearly,but seperate in the middle.

其中温度与叶片含水量间的联合作用效应更为突出。两叶螨间的微气候生态位在后期有较多的重叠，在前期重叠较小，而在中期是分离的。

Based on the previous research on the deposition of amorphous/microcrystalline silicon tandem solar cells, silane concentration for the deposition of microcrystalline bottom cell was selected to further optimize the performance for micromorph tandem solar cells using very high frequency technique. Finally, micromorph silicon tandem solar cell with 11.02%(Area=1.0cm2) initial conversion efficiency has been fabricated at a certain silane concentration and suitable light trapping structure.

采用甚高频等离子体增强化学气相沉积技术，在前期我们单室沉积的微晶硅薄膜太阳电池和非晶硅/微晶硅叠层太阳电池研究的基础上，通过对微晶硅底电池本征层硅烷浓度的优化，获得了初始效率达到11.02%（电池面积1.0cm2）的非晶硅/微晶硅叠层太阳电池。

And the conditions in cell suspension culture of Mikania micrantha were studied. The results showed that sucrose was the compatible carbon sucrose, and 30g/L sucrose concentration can satisfy the growth of Mikania micrantha cell; ammonium was absorbed under different sucrose concentration that haven't demonstrated significant specificity, and was completely absorbed on the lag phase and the early logarithmic phase; while nitrate was mainly absorbed on logarithmic phase. The density-dependent of Mikania micrantha cell starting to grow and density-inhibited of cell growth were proposed, the fittest inoculating quantity of Mikania micrantha in cell suspension culture was 40g/L.

并对微甘菊细胞悬浮培养条件进行研究，结果表明，微甘菊细胞生长适宜的碳源是蔗糖，并且较合适的蔗糖浓度为30g／L；在不同蔗糖浓度下氨基氮的吸收差别不大，氨基氮在迟滞期和对数期前期已基本消耗完毕，对数期生长主要利用硝基氮，因而提出，在微甘菊细胞液体悬浮培养中，氮源可以采用初始低氨基氮浓度，对数期中间维持高硝基氮，而且对数期中逐步流加少量的氨基氮；微甘菊细胞迟滞期分裂启动存在密度依赖现象，对数期生长存在密度抑制现象，最适接种量为40g／L。

But the creation of Mishima has respect of running through it all and adopting while making the transition as heir, i.e. the cognition of death and taking care of. The narration of death runs through the earlier and later stage in misima's novel creation.

但是，三岛的创作转型中也呈现出一以贯之和继承的方面，即对死亡的认知与观照，死亡叙述贯穿着三岛小说创作的前期和后期。

In 1990"s, Yu Hua veered to produce river novel."False work" is his former novels" summarization. Yu Hua pub I i shed "Ye I I in mizzle"-."See the sun" and "The biography of Xu san-guan selIs blood".

到了90年代，余华将眼光转向了对长篇小说的创作，以创作谈《虚伪的作品》作为对前期作品的总结，陆续发表了《在细雨中呼喊》、《活着》和《许三观卖血记》。

Monacha at the foraging site had a certain time budget rhythm in the breeding period. In the prophase of breeding, the male and female moved together at the foraging site in the whole day; the main activities of the male were feeding, guarding, walking around, maintaining and wooing, while those of the female were feeding, guarding, walking round and maintaining. In the anaphase of breeding, there were two stages every day when the male and female did their own activities at the foraging site (4:00~6:00 and 17:00~19:00), neither the male nor female had wooing activity.

在繁殖前期，雌、雄白头鹤全天(5：30~18：00)成对在觅食地活动，雄性个体以取食、警戒、游走、保养和求偶为主要行为，雌性个体以取食、警戒、游走和保养为主要行为；到繁殖后期，雌、雄白头鹤每天有两个时间段单独在觅食地活动（4：00~6：00和17：00~19：00），无论雌雄个体，均无求偶行为。

The results showed that pendimethalin is a herbicide interfering cell division,The mito-sis of pendimethalin treated root was arrested at metaphase with contracted and condensed chromo-somes and produced a series of abnormal,polymorphic cells such as multinucleate,multinucleolus,micronucleus and polyploid cells.
