Abstract : in simulating plant with radom iteration , the fractal picture can be controlled in detail by using probability . the fractal pictures acquired by treating its probability and colour are colourful and true to nature 文摘:在用随机性迭代算法进行植物模拟过程中,利用概率可以对分形图的细节进行控制,本文通过对概率和颜色的处理,使得到的分形图案丰富多彩,更加逼真

The main reason is that the distributation scale and quantity of the previous grand stress imported as the given factors are usually not definite , meanwhile the different quantity of the strate parameter such as e and n are radom to the different zone 其中最主要的原因是作为已知量输入的初始地应力分布规模和量值经常不明确,同时弹性模量、泊松比等地层参数的不同取值对不同地带具有一定的任意性。

So many statistics scholars have studied it extensively and obtained many ideal results . semiparametric regression model yi ~ ( n ) = xi ~ ( n ) + g ( t ~ n _ i ) + _ i ~ ( n ) , 1 i n , where g is an unknown function on a compact set a in r ~ p and is an unknown parameter , ( x _ 1 ~ ( n ) , x _ 1 ~ ( n ) ) ~ t , ? ? x _ n ~ ( n ) , t _ n ~ ( n ) ) ~ t are fixed design vectors and the radom er - rors _ i ~ ( n ) are assumed to be an l ~ q - mixingale sequences . fan [ 1 ] investigated nonparametric regression model 由于半参数回归模型的优点是集中了主要部分(即参数分量部分)的信息,因而它比传统的线性模型或非参数回归模型有更强的解释能力,不少统计学者对其进行了深入的研究,同其它回归模型一样,它的大样本性质始终是人们关注的热点。
