查询词典 drag force

In the first part, we report the application of a set of parallel dual tweezers, one stationary and one movable, to trap a polystyrene bead (suspended in de-ionized water) and drag it away from one of the trap centers beyond the linear (Hooke's spring) regime, to probe the nonlinear optical force constants associate with the optical trap.

在第一部分，我们建立了一个包含一道不动雷射光与一道可动雷射光的平行双道光钳，由此光钳钳住并移动悬浮於去离子水中的聚苯乙烯小球，使小球与其中一道光钳中心的距离远超出光钳的线性范围，来探讨光钳的非线性效应。

The parameters included drag-span ratio of cable,the value of prestressing force,the thickness of reinforced concrete floor,the cross area of tightwire and the number of prestressed tig.

利用ANSYS有限元分析软件建立了钢筋混凝土楼板模型和预应力空间组合结构模型，对楼板模型和预应力空间组合结构模型分别进行了模态分析，同时分析了垂跨比、预应力度、拉索截面面积、纵向连接索数和楼板厚度对预应力空间组合结构自振特性的影响

Considered the viscous drag, inert force and form effects imposed by the porous solid matrix to the flow, a turbulent combustion model based on fundamental equations of combustion in porous media was developed.

考虑了多孔介质的粘性力、惯性力及形状效应，以多孔介质中燃烧的基本方程为基础，推导出了多孔介质中的湍流燃烧模型。

Remember that the force required to overcome drag quadruples when doubling the speed, and what impact that have on aircraft weight.

记住当时军队要求在速度翻倍的情况下克服四倍的反作用力，并且飞机的重量对此有影响。

His team was asked to design a Mach 2 2.5 aircraft, which was then, and probably still is, a nontrivial task-especially when the objective is to create a "cheap" lightweight aircraft. Consider that the force required to overcome drag quadruples when doubling the speed, and what impact that has on aircraft weight.

要知道当飞行速度由单音速变为双音速时，空气阻力会增加至原来的四倍，考虑到因此所需要的动力，及其对机身重量的影响，满足这样的需求，即使是在今天也绝非易事。

This paper develops the mathematical models of the wind-sand interaction, taking the saltating cloud as fluidized flow. The force exerting on the airflow by saltating particles is expressed in terms of the drag coefficient of the fluidized particle flow.

本文将跃移风沙流视为一种颗粒拟流体，将跃移颗粒对气流产生的阻力用颗粒流的阻力系数来表达，建立了描写两场相互作用的数学模型。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
