查询词典 complex

Recently, with the increasing complexity of applications based on network, many complex systems have appeared to be typically autonomous, open, dynamic, and heterotopous. These systems make current software theories and technologies confront with many challenges, one of which is that mechanisms need to be provided with these complex systems from the point view of software architecture.

近年来，越来越多的以计算机网络为平台的应用系统表现出自主性、动态性、开放性和异构性的特点，这使得软件开发理论和技术需要从软件体系结构的角度对这类系统的开发提供支持。

It is concluded that if palladium ion coordinated with ligands is electron deficient and ligands have less steric hinderance, the palladium complex will have higher catalytic activity. According to this rule, we can tone ligand in palladium complex and improve its activity.

如果配体能使Pd〓的电子缺乏，具有较小的空间位阻，Pd配合物的活性就会提高，因此可根据这一结论对Pd配合物中的配体进行调配，提高其催化活性。

A new gene structure is proposed: head+body+tail, which allows the program with necessary complexity and putting some learning mechanism into the search process.② A new homeotic gene structure is proposed, it not only can call for subroutines easily, but also can automatically perform programming.③ The concept of different homeotic gene, a multi-cellular structure is proposed. It can be used to describe the complex multi-level programs and to implement the complex subroutine calls.④ An estimation of distribution operator for guiding search is proposed. It fuses statistic learning mechanism into the search process to accelerate the convergent process and improve the quality of solutions.

提出了一种新的基因结构：头＋身＋尾，使计算机自动设计的程序具有必要的复杂性，又便于引入学习机制；②提出了一种新的同源基因结构，它不仅可实现子程序的调用，还具有很强的编程能力；③提出了异族同源基因的概念：一种多细胞结构，它能描述复杂的多层次程序结构，实现可重用程序的复杂调用；④提出了分布估计变异方法，将统计学习机制融入算法，既提高了算法的收敛速度，又提高了解的质量。

Results Among the pre-schoolers,the hyperopia is primarily, specially the complex hypermetropic astigmatism. While among the school-age teenagers,myopia increases obviously,and the complex myopic astigmatism are most.

结果 学龄前儿童以远视眼为主，特别是复性远视散光最为多见，学龄期青少年儿童近视眼明显增多，其中复性近视散光最多。

From 1985 to 2000, woodland, grassland, industrial and residential land tended to be more inerratic and stable, whereas cropland and water area more complex and unstable. Unused land remained unchanged. During this period, the land use structure of Suzhou was unsteady, and its form became more complex.

从1985年至2000年，林地、草地以及居住与工矿用地趋于规则、稳定；耕地、水域用地趋于复杂、不稳定；未利用土地没有变化；苏州市土地利用结构不够稳定，土地利用形态趋于复杂化。

Displayed similar photophysical changes in the presence of DNA. But the complex increased the viscosity of DNA weakly. This suggests that due to the constraint from the rigid structure of the macrocyclic ligand, the complex binds to DNA by weak intercalative interaction.

在光谱方面也出现了类似的现象，但DNA的粘度却略有增加，说明环上的苯环可能由于受到整个配合物结构刚性的限制，只能以较弱的插入方式与DNA作用。

In addition, the complex of Rb with energic materials NTO was also studied, and many important achivements were gotted. Because these complex compounds are significant to the new sensitive dynamite and energitic katalyst, these results were receiving widely attentions from colleagues in our nation as well as in the world.

与此同时，对Rb、Cs等稀碱元素与NTO等含能材料的配位作用也进行了系统研究，取得了一系列重要的研究成果，由于这些配合物在未来新型高能纯感炸药和含能催化剂中具有重要作用，因而引起国内同行的广泛关注。

These results suggest that the diagenesis material of the Xiangshan volcanic intrusive complex was derived from crustal sources. The sources either had relatively lower maturity or had more juvenile mantle-derived igneous rocks than the exposed basement metamorphic rocks. Involvement of a small amount mantle-derived magma during the formation of the Xiangshan volcanic-intrusive complex was also possible. The diorite enclave, sub-quartzmonzonitic porphyry and lamprophyre were probably different mixing products between mantle and crust materals.

上述同位素示踪结果充分证实：相山火山-侵入杂岩的成岩物质主要为壳源，但与该区出露的基底变质岩相比，其物源区的成熟度相对较低或含有一定量的火成物质，并且不排除在其成岩过程中少量地幔物质的介入；闪长质包体、次石英二长斑岩及煌斑岩的成岩物质均含有一定量的地幔组分，可能为壳-幔混合作用的产物，只是受地壳物质混染的程度不同而已。
