查询词典 arbor press

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。

The results indicated that the content of organic matter of the natural meadow and the arbor forest land in the 0-20 cm surface soil grew separately by 36.11% and 32.96%; the nitrogen content of the natural meadow and the arbor forest land was also high, being 66.88 mg/kg and 69.37 mg/kg, respectively; the content of fast-acting potassium in the surface soil was higher than that of meadow ,while the activity of the urea enzyme, alkaline phosphatese and sucrase of the arbor forest land was stronger than that of the other four land utilization modes.

结果表明，天然草地和乔木林地10~20 cm表层土壤有机质增长率均较大，为36.11%和32.96%，二者碱解氮含量也较高，分别为66.88和69.37mg/kg；乔木林地和灌木林地0~20 cm 表层土壤有效磷含量均高于天然草地和人工草地，乔木林地速效钾含量最高。

Meso phanerophytes and micro phanerophytes are main composing plant of arbor synusia in the area.In synusia structure,except for the warm shrubs,frost flora all have arbor synusia,shrub synusia,herbage synusia and lichen synusia.The evergreen broad leaved meso phanerophytessynusia dominates the arbor layer .

在层片结构上，森林植物群落除暖性灌丛外，都具有乔木层层片、灌木层层片、草本层层片和苔藓地被层层片，常绿阔叶中高位芽层片为乔木层主要层片，并多构成群落的建群层片。

During the investigations, some basic research methods and theories such as mending the end section profile of the screw arbor gear applying the conjugate principle, the milling outline for the screw arbor profile cutter by kineto-synthesis method, establishing the dummy variable model of the screw arbor by the CAD method, the theory of the distributing of the fluid pressure on the screw, the precision analyzing and computing screw profile by the dummy model and FEM method are established.

在研究过程中确立了一些基本的研究方法和基本的理论。如应用共轭原理改进螺杆端截面齿曲线的、利用运动合成的方法研究螺杆成形铣刀廓型、应用计算机辅助设计的方法建立螺杆的虚拟模型、应用牛顿流体理论研究螺杆中的流体压力分布、应用有限元分析计算方法对螺杆做精确分析计算。

Because the workpiece is in dynamic balance, the resultant moment acting on it should be zero. Introducing the moment from lapping tool and press head a moving differential equation is built. In this equation only workpiece rotating speed is unknown. It means that workpiece rotating speed can be got by this equation. Since there is a transcendental function in integral function of the equation an analytic result can not be got, only digital result can be got by a computer. Thus a change rule of workpiece rotating speed with lapping parameters is known, e.g. the radius of press disc ball socket, radius of press head ball, the distance between the workpiece rotating axis and lapping tool rotating axis, workpiece radius, modulus of elasticity of the press head and press disc, friction coefficients between the lapping tool and workpiece, and between the head and disc, pressure between the lapping tool and workpiece and pressure between the press head and press disc.

因工件处于动态平衡状态，其上所受到的来自于磨具和压头的力矩应相等，将二力矩表达式联立，建立工件运动微分方程，该方程中只有工件的旋转角速度是未知量，因此可以求出工件旋转角速度，但该方程积分式中含有超越函数，得不出解析解，只能通过计算机求出数值解，得出工件旋转角速度随各研磨参数的变化规律，如压盖球座半径、压头的球头半径、工件回转中心相对磨具回转中心的偏心距、工件半径、压头和压盖材料的弹性模量、磨具与工件间的摩擦系数、压头压盖间的摩擦系数、磨具与工件间的压强、压头压盖间的压力等。
