未知

By applying the concept of "dominant input",the existence of both the approximation error and external disturbance which are supposed to have unknown boundaries is considered.What's more,the adaptive law utilizes two types of errors in the adaptive fuzzy systems,the tracking error and approximation error.

该方法应用"主导输入"的概念，同时考虑了函数逼近误差和系统外扰的存在，假设了该系统逼近误差和系统外扰有界但界未知的情况；并探讨了自适应模糊控制器的参数自适应律由跟踪误差和逼近误差共同进行调节。

LBIE, based on the local boundary equation, adopts the traditional moving least squares approximation which depends on only the values of the nodes in the domain of the problem or along its boundary. The whole process of integration is carried on over a local domain or its local boundary centered at the node in question. The local boundary equation can be rewritten to represent the values of the unknown function at the point of interest, and the essential boundary conditions can be directly and easily enforced by using the Green formula and the characters of the Dirac function.

它以局部边界积分方程为基础，采用移动最小二乘近似函数，从而只需要分布在问题域内及其边界上的节点的信息值，无需划分单元；整个积分是在以节点为中心的局部域及其边界上实现，所以不需要背景积分网格；借助于格林公式及Dirac函数的性质，将局部边界积分方程转化为所考虑点的未知函数的边界积分表达式，便于直接施加本质边界条件。

This paper is a generalization of the result in [2]. We prove that the least squares estimator of the regression coeffcient is admissible for a wide class of distributions when the variance σ2 is unknown.

这篇文章是成平结果的一般化，即在一个宽广的分布类中，证明了当方差未知时，回归系数最小二乘估计是容许的。

6Although common prejudice still believes that the sole essential basis of our knowledge is given exclusively from outside and that "nihil est in intellectu quod non antea fuerit in sensu, it nevertheless remains true that the thoroughly respectable atomic theory of Leucippus and Democritus was not based 0 any observations of atomic fission but on a "mythological" conception of smallest particles, which, as the smallest animate parts, the soul-atoms, are known even to the still palaeolithi inhabitants of central Australia.9 How much "soul is projected into the unknown in the world of external appearance is, of course, familiar to anyone acquainted with the natural science and natural philosophy of the ancients.

虽然普通的偏见依然相信我们知识的唯一的本质的基础是来自外部世界，and that "nihil est in intellectu quod non antea fuerit in sensu，路斯帕和德谟克利特令人敬佩的原子理论并不基于任何对原子裂变的观察，而是基于"神话的"最小粒子的概念，这是作为最小的有生气的部分，灵魂的原子，这些也为中澳大利亚旧石器时代的居民所知。有多少"灵魂投射进世界外观的未知中，当然，也和任何人所熟知的古代人的自然科学、自然哲学相似。
