1909年保罗·哈维兰在纽约(在克拉伦斯·h·怀特的画室)拍摄的一张照片展示的是舞蹈家Faico,他的膝盖微微弯曲着,手臂保持着反向曲线。
One taken by Paul Haviland in New York in 1909 (in Clarence H. White's atelier) shows the dancer Faico, his knees slightly bent, his arms holding opposite curves.
如果曲线向上弯曲,那就糟糕了。因为更多的负载意味着每请求的成本更高。
If it curves up away from a straight line, that's bad, because more load means a greater cost per request.
照片显示珠峰北坡被冰雪所覆盖,在它下面“大绒布”冰河以大幅度弯曲的“S”型曲线穿过广阔并充满岩石的峡谷。
It showed the ice-encrusted north face of Everest and, below it, the great river of ice known as the Main Rongbuk Glacier, flowing in a sweeping, S-shaped curve down a broad, stony valley.
The force may taper off, the force may not be given by a straight line, but for modest deformations, every spring will have a linear regime in which the force is linearly proportional to the stretching.
它产生的力可能会渐渐消失,力的曲线可能不是一条直线,而有轻微的弯曲,每个弹簧都有一个线性区间,在这一区间内,力和伸长量是线性关系
