let circumference = 2 * PI * radius; 在这个例子中,PI是一个常量,radius和circumference是变量,代码的意图非常明确。 2、便于团队合作 在团队合作中,统一的编码规范可以减少代码审查和合并时的冲突。大写常量是一种简单但有效的规范,能够帮助团队成员快速理解代码。 三、防止意外修改常量的值 1、增加代码的鲁棒性...
Because of its construction, the drive cable is very flexible and can be bent, without fracture, to a very small radius. This is handy because the cable must snake its way from the transmission to the instrument cluster, which houses the speedometer. It is connected to a set of gears in...
The mode of propagation can be expressed by a very simple mathematical law, which is, the current at any point flows with a velocity proportionate to the cosecant of the angle which a radius from that point includes with the axis of symmetry of wave propagation. At the transmitter, the co...

Centrifugal force: This force is acting on the object away from the center of the circle. The magnitude of both the forces are same. It is given by, F=mv2r Where, m = Mass v = Speed r = Radius of the circular path Answer and Explanation:1 ...
wall stress is an expression ofpreload. It is proportional to the state of deformation to which the parietalmyocardiumis subjected, therefore it depends on endoventricular pressure, radius of the circumference, and thickness of the wall itself.12From a mathematical point of view, the relationship ...
The planetary gear mechanism 526 includes: a sun gear 531 that integrally rotates with an input side transmission gear 529 rotatably supported on the input counter shaft 28; a carrier 532 rotatably supporting a plurality of planetary gears 533 on the same radius; and a ring gear 534 with an...
Such a concave surface 1102 may be of a shape mathematically defined by depth as a function of radius from the axis 1103 being a constant minus radius raised to a power greater than two. If the rear surface 1102 is concave, it may alternatively be of a different shape or it may even ...
