In particular, by introducing the force constraint between midrib and parallel venation, the dynamic simulation of leaves can be vividly performed.

针对以往研究中植物建模主要集中在对植物器官静态结构的仿真，通常会忽略树叶或花瓣的厚度问题，本文根据阔叶植物的自然属性，利用植物的茎枝和叶片结构的相似性，采用具有厚度信息的3D叶片建模方法，通过叶片平行脉位置方向的弹性约束关系来有效控制叶片的动态仿真。

And 43. 0%～75. 0% through added chicken manure to soil and the multiple cropping that transplant hyperaccumulators after them be cropped at their flowering stage.

In this dissertation,Psoralea corylifolia L.was selected as plant material through antifungal activity screening.

通过对植物病原菌具有抑菌活性植物的筛选，得到广谱、高效的目标植物-补骨脂(Psoralea corylifolia L。)。

The main results are as follows: l.The olfactory response of Tetranychus viennensis to different plants odors: Olfaction takes part in the response during the hawthorn spider mite looking for host plants, that means Tetranychus viennensis were attracted by odors from host plants.

结果如下：1。山楂叶螨的雌成螨对不同植物叶片挥发性物质的嗅觉反应：山楂叶螨在寻找寄主植物的过程中，嗅觉参与反应，即山楂叶螨能被寄主植物释放的气味物质所吸引；不同的寄主植物对山楂叶螨的引诱程度不同，苹果、梨等的引诱作用较强(着螨率95％，77.5％)，日本樱花的引诱作用较弱(着螨率45％)。

In the leaves of Liriodendroideae, some of the abaxial epidermal cells are papillose and the vascular tissue of the main vein appears to be separated. However, papillose were not found and there are uniseriate, multicellular or unicellular hairs distributed on the epidermis, and the vascular tissue of the main vein appears to be continuous in the leaves of Magnolioideae. Furthermore, in the Magnolioideae, the structure of the leaves of plants in Manglietia are different from that of Magnolia.

结果表明：鹅掌楸亚科和木兰亚科在叶的结构上的主要区别是鹅掌楸亚科两种植物叶的部分下表皮细胞呈乳突状，且整个细胞外壁只形成一个乳突，而在木兰亚科的植物中有单列多细胞或单细胞的表皮毛，未发现乳突；鹅掌楸亚科植物的叶主脉维管组织环分隔呈束状，且其外包被的纤维也排列成束状，而木兰亚科的80种1亚种植物中，叶主脉维管组织连成轮状，其外面也由一圈连续的纤维环所包围。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
