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...

;CONSTITUTION: A segment 1 is made up of a base part 3 of a circular-arc-plate shape formed with the same radius of curvature as the outer circumference of a shield and a projected part 5 of a circular-arc-plate shape, and the projected part 5 is projected from the center of the ...
the: bed as a whole. This may be explained by reference to Figure 4, wherein the 2 2,314 circle is representative of a roller. The bottom tangent line of length B may be considered a unit distance which happens to be here shown but does not have to be equal to the roller radius....
describe a straight linethat starts near one gear and ends up near the other. This means that the radius of the contact point gets larger as the teeth engage. Thepitch diameteris defined as "the imaginary diameter for which the widths of the threads and the grooves are equal,"according to...
Torque is the measure of twisting force, calculated as the product of circumferential force multiplied by the radius of the gear. This means that bigger gears will have more torque than smaller gears because of the larger radii of the gears. What is the purpose of gear ratio? The primary pu...
Also, in one implementation, the groove may include a first concave surface extending from the reference plane to the first depth. The channel may comprise a second concave surface extending from the reference plane to the second depth. The first concave surface may have a first radius of curva...
When I was debugging, I felt like the picking stops working if the picked position is out of the circumference of some radius calculated from the center of the graph, like this: Here is a video of it, I don't get the math yet, do you think something like this might be possible @pi...
The variable was computed within buffers with a radius of 1000 m centered on participants’ residences. These buffers took into account the street network, i.e., comprise the area that is accessible within 1000 m along the street network. ArcInfo10 and its Network analyst applied to street ...
