无结构

The reciprocity between PPCG and caffeine molecule was also simulated and calculated.It was found that the caffeine molecule was selectively distributed in CO2 habitat,but never in γ-butyrolactone habitat.

通过对PPCG与药物分子咖啡因相互作用的分子模拟和计算，进一步了解咖啡因分子是选择性地分布到CO2结构单元的区域中，而在GBL区域无分布。

The 'Hoop Cable Air Bag' is one step above the cableless air bag, due to some additional stability against high winds, but as discussed in the above structural integrity comparisons, there is very little improvement in the ability to cope with snow loads and high winds.

纵横钢缆充气包是无钢缆充气包的进一步提升，因为其通过增加额外的稳定性来抵御大风。但正如之前所讨论过的结构稳定性的比较，对于抵抗风雪而言，纵横钢缆充气包也仅仅能提供很小的提升。

The cableless dome or 'air bag', is only capable of a maximum of 1.5-1.6 wsp which will provide maximum stability against 60-75 mph winds and a snow load of 5-6 lbs.

无钢缆充气包的最大内压可以达到1.5-1.6英尺水柱，在确保结构稳定性的前提下，可承受的最大风速为每小时60-75英里，最大雪载为每平方英尺5-6磅。

The intersupplemental relation and separate function of these models are discussed, and the theoretical support is provided for developping the general CAE system on the launch dynamics of auto-rifle. The dynamic matching relation for caseless rifle is also discussed and the dynamic characteristics on new type caseless rifles with different constructure parameters are studied.

讨论了各模型之间相互补充的关系和各自的功能，为发展自动步枪发射动力学通用CAE系统提供理论支撑；本文还讨论了无壳弹枪的动力匹配关系，分别对不同结构参数的新型无壳弹枪的动力学特性进行了研究。

Pseudoverticillata, but there was no significant change in Celtis wightii. There was no significant change in leaf area specific hydraulic conductivity K(subscript l between the two seasons in all the three species, which may caused by the adjustment in hydraulic architecture through partial loss of leaves during the dry season. In the dry season, maximum carbon assimilate rate A(subscript max was significantly lower than that of the wet season in all the three species.

除油朴的枝条边材比导率K(下标 s在旱季和雨季没有显著性差异外，尖叶闭花木和轮叶戟的K在旱季都有显著的降低；而枝条的叶比导率K(下标 l三树种在两个季节间均无显著变化。K在旱季没有显著性降低，可能是常绿树种在旱季通过脱落部分叶片以调整其水力结构来保持较高的单位叶面积的水分供应。

There were only 94 vascular plant species, belonging to 50 family and 75 genera. The dominant species in the communities were deciduous broadleaf species Liquidambar formosana, Robinia pseudoacacia, Ailanthus altissima, Acer buergerianum, and Celtis sinensis, evergreen broadleaf species Cinnamomum camphora and Elaeocarpus glabripetalus, and Phyllostachys heterocycla. Robinia pseudoacacia+Cinnamomum camphora community had the highest Shannon-Wiener index (1757) and Phyllostachys heterocycla+Acer buergerianum community had the highest Simpson index (0163), but no consistency was observed between the curves of H and D. For vertical structure, most communities had no significant understory stratification.

结果表明：辰山植物区系以泛热带和北温带占优势，具有典型亚热带和温带成分交汇和南北植物分布交错特征；但保育区内种类单一，维管束植物仅有49科69属94种；主要群落是以枫香、刺槐、臭椿、三角枫和朴树等为优势树种的落叶阔叶林，以香樟和秃瓣杜英等为优势树种的常绿阔叶林，以及毛竹林；物种多样性普遍较低，Shannon-Wiener多样性指数最高为刺槐+香樟群落（1.757），Simpson均匀度指数最高值为毛竹+三角枫群落（0.163）；多样性指数曲线和均匀度指数曲线不具有一致性的变化趋势；多数群落垂直结构中无明显林下分层现象；演替前期的落叶乔木种群后续个体不足。

During the development of dental germ, enamel matrix proteins secreted by epithelial root sheath could induce dental follicle cells to differentiate towards cementoblast and form acellular cementum finally on the surface of tooth root. Many researches of domestic and oversea scholars suggest that enamel matrix proteins could effectively induce periodontal regeneration, and the structure and function of this regenerated tissue are similar to healthy periodontal tissue. Moreover, the regeneration process is nearly the same to that of embryonic development of periodontal tissue.

自发现釉基质蛋白可诱使牙囊细胞向成牙骨质细胞方向分化并在根表面形成无细胞性牙骨质以来，国内外学者做了大量研究，结果表明釉基质蛋白能有效诱导牙周组织的再生，且这种再生组织的结构和功能更接近于健康的牙周组织，并且再生过程也与牙周组织的胚胎发育过程类似。
