The results shows that the REE of Shuixigou Group came mostly from andesite and granite in the denudation zone,but did not originate from basalt.The pH values of the interlayer oxidation rock zone and the primary reduction rock zone are similar,and those of ore zone are lower than the other two zones.

In chapter 3, prediction theory of time series is reviewed, then non-linear autoregressive model of time series-feedforward neural networks is presented, at the same time a new method-SVD is proposed to design the architecture of feedforward neural networks. By using a trained network with a sufficient number of hidden nodes, according to the distribution of singular values of hidden nodes outputs, we can decide the optimum number of hidden nodes, then the reduced network will be retrained.

第三章：先回顾了时间序列的预测理论，提出了时间序列的非线性自回归模型-前馈神经网络模型，并提出了一种设计前馈神经网络的新方法-奇异值分解法，初始网络结构足够大，网络训练后，对网络隐层节点输出所形成的矩阵作奇异值分解，根据奇异值分布情况，决定网络隐层节点的个数，优化后的网络重新开始训练。

In this thesis, by using the theory and method of value distribution, we mainlyinvestigate the definitions and relationships among the except values and except valuessets of the meromorphic functions.

中文摘要：本文运用值分布理论和方法整理了亚纯函数各种例外值的概念，并且总结了例外值集之间的相互关系。

A novel lightly-doped channel approach for linearity improvement of InGaP/InGaAs pseudomorphic high-electron-mobility transistor device was presented. Light doping in the channel region of the conventional δ-doped InGaP/InGaAs PHEMT was adopted to provide a uniform and symmetric electron distribution in the channel region to achieve flat extrinsic transconductance distribution under different gate bias conditions.

本次实验在传统矽平面掺杂元件结构的通道区域中加入微量的杂质浓度掺杂，使得电子在元件通道层中的分布更为均匀及对称，以期望在不同的闸极偏压条件下得到较为平坦的转导值分布曲线，改善磷化铟镓/砷化铟镓假晶式高电子迁移率电晶体的线性度表现。

By way of eight experiments and statistical analysis of loads of overhead crane in actual usese, we have got that the lifing load is stationary, normal and homogeneous Poisson, and got distribution function of lifting load, the load spectrum factor, the rain-flow counting results of stresses and statistical results of location of the trolly, that will provide a large number of datas for reliabilitic design of overhead crane.
