That looks very familiar. 则现在,必然等于 m乘以向心加速度,嘿,看起来太眼熟了。163 So what I did was I plotted this data, the centripetal acceleration versus the mean distance to the sun and I did that on log paper. 于是我用对数坐标,作了张图,列出了向心加速度,与平均距离的关系。163 So for the water to be ejected from the fur, the centripetal force has to exceed the surface tension. 所以,要让水从皮毛弹出,向心力必须超过表面张力。 yeeyan This ball is feeling a pull from the string and that provides it with the centripetal acceleration. 小球受到绳子的拉力,这就是向心加速度的来源。163 This top-heavy state, the legacy of centripetal policies since the war, is no clunkier than the language of those keenest to reform it. 战后的集中化政策带来的这个臃肿的政府的笨拙,比起那些最激进的改革分子所描述的,也好不到哪去。 ecocn This development carries the potential to reverse the unhealthy centripetal forces that conventional personal computers have introduced into life and the workplace. 这种发展具有的潜力能够扭转传统个人计算机带入生活和工作的不健康的向心力。 yeeyan Water is attached to the dog by surface tension, they thought, and the sinusoidal shaking creates centripetal forces that ejects that water off the body. 他们认为水沾在身上靠的是身体表面的亲和力,正弦波状的抖动动作制造了水脱离身体的离心力。 yeeyan Centripetal, pointing towards the center. 向心,即指向圆心。163 |
