查询词典 Chen

The seabuckthorn carpenter moth, Holcocerus hippophaecolus Hua, Chou, Fang et Chen is recently a major pest of seabuckthorn in Inner Mongolia Autonomous region, Liaoning, Shanxi, Ningxia and Shaanxi provinces in China. The generation time of H. hippophaecolus is four years. The larvae cause damage primarily to the stems and roots of seabuckthorn, and the mature larvae pupate in soil.

沙棘木蠹蛾(Holcocerus hippophaecolus Hua， Chou ， Fang et Chen)是近几年在内蒙古、辽宁、山西、宁夏和陕西等地大面积爆发的一种钻蛀性害虫，该虫约4a完成1代，主要以幼虫危害沙棘的根部和干部，老熟幼虫在土壤中化蛹。

Based on Chen's model about axial flow induced vibration of a rod bundle in an unbounded domain, a mathematical model concemed with circular domain is presented, and the expressions for fluid forces are given in detail.

三、基于Chen关于无界域轴向流动中棒束流致振动的模型，推导了有界域棒束轴向流致振动的数学模型，得到了关于流体力的表达式。

Basis on this result, Chen, Lih and Wu put forth the following conjecture:Conjecture 2 For any connected graph G, except K_m, C_(2m+1) and K_(2m+1,2m+1) for all m ≥ 0,then G is equitably △—colorable .

基于这一结果，Chen，Lih和Wu提出了以下猜想：猜想2：如果图G是一个既不是完全图，奇圈又不是完全二部图K_(2m+1，2m+1)，m≥0的连通图，那么G存在均匀Δ-染色。

In this paper, a "rigid bar relative movement model" was established to illustrate the traces of the helices in wire ropes. The angular speed of a moving particle of the model was relatives to curvature tensor to derive the curvature components and torsion of helices in multi-layer wire ropes. According to long and thin rod theory of Love and Yen-Chen's theoretical model considered the contact force and frictional force, the force-deformation or force-strain relative of wire in curved wire ropes subjected axial force is derived from the curvature components and curvature increment.

本研究改以刚杆相对运动模型，直接描述钢索中钢绞线轨迹，并且透过角速度类比曲率张量之概念，推导圆弧型多层钢索内部之钢铰线之曲率分量与扭率；之后再依据Love的细长杆理论，辅以Yen-Chen在考虑接触力及摩擦力下所修正之理论模型，以曲率及曲率增量来探讨圆弧型钢索受静态荷重作用下，钢绞线之受力与变形或应变关系。
