Pixel values in an image window are taken as a realization of a BN, and the structure and parameters of BN for each texture class are then studied. The conditional distribution probability of the pixels is used as the feature for texture classification.

把纹理图像在一个窗口内各个像素的灰度值看作贝叶斯网络的一次实现，通过训练得到各类纹理所对应贝叶斯网络的结构和参数，用纹理图像像素点在网络中的条件概率分布作为特征进行纹理分类。

It employs the complex-valued step function to build neural model, then constructs network structure and decides the number of neurons; it adopts complex-valued Hebbian rules and inner product way to calculate the net weight matrix; then it analyzes the convergence of the network by taking advantage of the definition of energy function. In the image pre-processing stage, 2-dimensional Fourier Transform and Euler's formula are used, respectively, to transfer a gray-scaled image into phase information needed by the complex-valued neural network when stores the traffic sign. In the image post-processing stage, phase inverse transformation is used to change the phase image to gray-scaled image.

采用复数阶跃函数构建了神经元模型，建立了复数Hopfield神经网络结构，并且确定了网络中神经元的个数；借助复数Hebbian学习规则和复数内积法给出了网络权值的确定方法；借用复数网络能量函数的定义，说明了复数识别网络的收敛性；在前期的图像数据处理部分，分别使用离散二维傅里叶变换和欧拉公式，给出了将灰度图像数据转化为复数网络所需要的相位信息的方法，实现了网络对路牌的记忆存储；在后期的图像还原部分利用相位逆变换的方法，实现了相位图到灰度图转化。

The results showed: Difference of rice striper on different varieties was significant,positive correlation was between amount of hopper and rice striper generation.Late sowing and simple cutivation would be helpfull for reducing rice striper in early period.

结果表明：不同水稻品种间条纹叶枯病发病程度差异明显；而灰飞虱发生数量与条纹叶枯病的发生程度呈正相关；而推迟播期、推广轻简栽培方式有利减轻前期水稻条纹叶枯病的病情。

Through the methods of polarizing microscope and cathodoluminescence, the diagenesis of Late Carboniferous phylloid algal reefs in southern Guizhou is studied, which indicates diagenesis are mainly of bio-binding and baffling actions, micritization, cementation, compaction-pressure solution, fracture, recrystallization and dissolution in type.

东北大学资源与土木工程学院，沈阳110004通过偏光显微镜研究和阴极发光技术，对黔南晚石炭世叶状藻礁灰岩的成岩作用做了详细研究，认为礁灰岩主要成岩作用类型有：生物黏结障积作用、泥晶化作用、胶结作用、压实压溶作用、破裂作用、重结晶作用和溶解作用等。

The proportion of the viruliferous Laodelphax striatellus is the most important factor for the epidemic of the disease, so a rapid and sensitive method is necessary for detection of RSV in Laodelphax striatellus.

灰飞虱的带毒虫量是条纹叶枯病发生流行的主要影响因子，因此建立一种快速、灵敏检测灰飞虱带毒率的方法是迫切需要的。
