This method is also suited to design approximation function of passive filter.
这种方法同样适用无滤波器的近似函数设计。
An approximation function of the fractal image regardless of black and white or colour can be considered as a fuzzy set. So the research of iterated fuzzy set system (IFZS) is necessary.
分形的黑白图象和彩色图象之逼近函数可以看作一个模糊集,因此对迭代模糊集系统IFZS的研究是极有必要的。
If you want strict equalities in approximations means that we replace the function by its tangent approximation.
如果你想要严格的近似等式,那就意味着我们要用切线逼近来取代原函数。
So, we can say that a circle is a good approximation for a 1 s wave function.
所以我们说一个圆是,对1s波函数的好的近似。
