However remarkable impacts were observed in the plantation in terms of community physiognomy,community structure,species composition,species richness,and biomass accumulation.1 Planting trees made community structure simple.Betula alnoidis plantation had three layers including a dominant arbor layer,a complex and well developed shrub layer and a poorly developed vine layer.The arbor layer contained few species and had a single layer.The mountain rain forest had 4 layers including the dominant arbor layer,shrub layer,grass layer and vine layer.The vine layer was well developed and very rich in species composition,and the arbor layer contained as many as 38 species that could be grouped into 3 layers.2 Sequenced by the important value,main species for the plantation and the nature forest were totally different,and the plantation had one dominant species while the nature forest contained many dominant species.3 Planting trees changed the community physiognomy.
但是人工种植西南桦林对群落的季相外貌、群落的结构、物种组成、物种丰富度以及生物量等方面有较大的影响。1人工造林使得群落结构简化,西南桦人工林的层次结构有3层,以乔木层占优势,并且有种类多而发达的灌木层,同时,藤本植物欠发达,但是乔木层树种单一,明显仅有一层;山地雨林的层次结构有4层,以乔木层占优势,还有灌木层、草本层和藤本植物,藤本植物种类多,十分发达;乔木层树种丰富,可达38种,乔木层还可分为3层。2人工造林较大程度地改变了群落的物种组成,根据重要值的大小排列,人工林和天然林的主要物种组成已经完全不同;并且人工林单优树种明显,而天然林就含有较多的优势树种。3人工造林改变了群落的外貌。

In order to improve the efficiency, an implementing scheme (according to the distribution of strain energy density) was suggested when to consider the fact that the high gradient usually appears only in a very local region, especially in the case of huge amount of computation. All programming has been finished on the platform of commercial codes Mathmatica and Fortran.4. A number of numerical examples and applications were presented to verify the proposed Bezier-Based Element Method. The engineering cases include: the belt die for diamond synthesize, the main frame of wire-rounded press, the hydraulic cylinder of open die forging press. The numerical results show that the BBEM has some good performances.
通过大量的数值算例来考证所构建的各种类型单元,并应用于人造金刚石年轮模具、钢丝缠绕预应力机架和液压机工作缸等实际问题的结构分析;结果表明:所构建的Bezier耦合单元具有描述较大梯度变化场(如位移场、应力应变场等)的能力,该方法不改变单元的大小和形状,保持单元的自由度数不变,而通过调节中间可动节点的位置改变单元内部的场分布,只需少量单元即可较精确地模拟较大的梯度变化;可为有效求解高梯度问题提供新思路,对实际工程应用具有重要意义。

The engineering cases include: the belt die for diamond synthesize, the main frame of wire-rounded press, the oil cylinder of open die forging press. The numerical results show that the BBEM has some good performances. With few elements, the BBEM can lead to a high accuracy. If using same DOFs, the computing precision of BBEM is remarkable higher than that of the conventional FEM.

The simulation results show that the spring stiffness and initial force have important effect on the poppet valve's opening displacement, the delay-closing time and the closing velocity, and there must be an optimal matching between those two spring factors.
仿真结果表明,在同时保证阀芯有较大的开启度和较短的滞后关闭时间时,弹簧刚度和预紧力因素之间存在着最佳组合:k=10 N/cm,f=15N;同等地改变预紧力比改变弹簧刚度,对阀门的运动影响更大。

The metals, such as Fe, Cu and Co, which can be reduced by KBH〓, can not change the catalytic properties obviously if only small amount of them are added to Ni-B alloys; those who can not react with KBH〓, such as Zn〓, are washed out during the preparation, so they also can not change the catalytic properties; while addition of the elements in VIB group, such as Cr, Mo and W, can increase the hydrogenation activity magnificently.
同样,我们通过添加第三组分来修饰Ni-B合金,可以被还原的金属,如Fe、Co、Cu等,少量添加并不能明显改变其反应性能;而与KBH〓不发生反应的金属,如Zn,以离子形式加入后,除了少量离子被吸附在催化剂表面外,基本不残留在催化剂里,因此对反应性能也没有太大的改变;只有VIB族元素,如Cr、Mo、W的加入才会很大改进Ni-B催化剂在蒽醌加氢中的催化性能,尤以Cr的修饰作用最好。
