求解接触刚度，用经典的Hertz方法求解理想情况下 刚度随载荷变化的关系(contact stiffness)

说明：  实际的数值是带有符号的，即可能是正数，也可能是负数，数值的正负之分如何实现？ 通过补码表示，且用一位符号位区别其正负即可。 而数值本身可以包括整数，也可以包括小数。那么，在计算机中是如何确定小数点的位置呢？ (The actual value is unsigned, which may be positive, it may be negative, positive and negative values divided how? By complement representation, and with a bit different from the positive and negative signs can be. The value itself can include an integer, it can also include decimals. Then, the computer is how to determine the decimal place?)
