draw a circle

基本解释

Indeed, the corresponding vector image has only one instruction: "Draw a circle of 50 pixels."
事实上，与这幅图对应的矢量图形只有一条指令：“绘制一个直径为 50 像素的圆形。”
My impulse is to share them, to draw a circle of stillness around them so they can touch and inspire others.
我有一种要分享它们的冲动，在它们四周画出一个静止凝固的圈，使它们能打动和启发其他人。
Furthermore, the larger circle does not require a significantly larger file (it becomes "draw a circle of 100 pixels").
更进一步说，如果圆形变大，存储它的文件并不会更大（只是变成了“绘制一个直径为 100 像素的圆形。”）

It makes sense to draw the wave function as a circle, because we do know that 1 s orbitals are spherically symmetric.
把波函数画成一个圆是有道理的，因为我们知道1s轨道是球对称的。
