hyperbolic curve meaning in Chinese

双曲线

Especially , paper research that the k - order rational b - spline function change to polynomial b - spline when h limit to 0 , + . last the spline function can be used to express the hyperbolic curves . then , when k = 3 , 4 , paper research the infection of curve because qi is changed
当形状参数h 0 ~ + , +时, k阶指定极点有理b样条退化成多项式b样条,最后还给出了双曲线的精确表示
This paper has broaden the concept of maximum likehood estimate , put forward a new concept : so called " direction maximum likehood estimate " , and has proved the isosceles hyperbolic curve relationship of parameter , under the condition of normal distribution and logarithm normal distribution
