正常人和左侧偏瘫患者各区力向量均值在训练后均有明显改善(P<0.05)。
The average force vector quantities in all area were improved after training in the left hemiplegia and the healthy people(P<0.05).
飞行中的飞机以外的悬停控制叶片被用来创造一个倾斜力向量机在希望的方向就像直升机旋翼。
To fly the aircraft in anything other than a hover the control vanes are used to create a force vector to tilt the machine in the desired direction much like a Helicopter rotor.
再根据哈密顿原理导出了悬索大挠度振动的有限体积离散方程,推出了索的整体节点力向量、质量矩阵和切线刚度矩阵。
The final finite-volume discretization equations are derived using the Hamilton principle. Meanwhile the global nodal force vector, mass matrix and tangent stiffness matrix of the cable are obtained.
我们用这个点的,位置向量,乘以这个力。
We have the cross-product of the position vector to this point times the force.
希望大多数人都知道电场是向量场,电场描述了,对场中的带电小颗粒的力的作用。
Hopefully most of you know that the electric field is a vector field that basically tells you what kind of force will be exerted on a charged particle that you put in it.
我们还知道,如果力是由势产生的,那么其旋度是,这就是我们得到的,关于从势产生的向量场的准则。
There is another thing that we know because if a force derives from a potential 0 then that means its curl is zero Thats the criterion we have seen for a vector field to derive from a potential.
你知道……不是向量的长度决定……是你用多大的力决定。
You know.. it’s not the length of the vector that counts… it’s how you apply the force

You know.. it's not the length of the vector that counts… it's how you apply the force
物体质量为,因此有重力,我可以用向量符号,表示这个力。
M the object has a mass m, mg and so there is a force mg, and I can write down the force in vector notation.
然后,采用小波包对采集的铣削力信号进行分解和消噪处理,并提取其能量特征作为BP神经网络的输入向量。
Then, wavelet packet was used to decompose and de-noise the milling force signal, as well as extracts the signals 'energy characteristics as import vectors of BP Neural Network.
