The direct removal of coal ash by the negative pressure generated by a negative pressure fan,features less investment,simple system,simultaneous carriage and sorting ,and good airtightness,but its stability is poor,and it causes serious wear of pipeline and negative pressure fan as well.

负压取灰是利用负压风机所产生的负压将干灰直接取出的一种取灰方式，具有投资小、系统简单、可以同时实现输送和分选及密闭性好等优点，但是稳定性比较差，对管道和负压风机磨损较为严重。

Valve: The sealing performance between valve check and seat ring will be damaged because of worn and corrosion. If this occur, close the main valve and take down the valve clack to polish.

阀门：吹灰器阀门因为吹灰介质的磨损和腐蚀，会引起阀瓣与阀座环间密封性的破坏，如果出现这种情况，应关闭吹灰器总阀，取下阀瓣研磨。

Based on the dual pore structure model and analysis of the marlite reservoir response characters of Shulu basin,establishes the optimum log criteria for marlite reservoir evaluation,points out the limitation of conventional log data,and determines the reservoir evaluation standards.

以双重孔隙解释模型为基础，通过对束鹿凹陷泥灰岩储层特征和测井响应特征的分析，在现有测井资料基础上探讨泥灰岩地层中测井系列优选原则，指出常规测井资料的不足和局限性，确立了泥灰岩储层评价标准。

Some important properties of singular value vector of color face image were proved,and then it was extracted as algebraic feature and applied to color face recognition.

由于灰度图像易处理、灰度人脸图像库易获取的特点，大多数人脸识别方法都是基于灰度人脸图像的。

Within these thirdorder sequences, there are many subtidal carbonate cycles that are made up of both the mediumto thinbedded aphanitic micrites and the thinbedded marls in the transgressive and the early highstand system tracts, and many grotesque sedimentary structures are developed in the bedding planes of aphanitic micrites.

在这些三级层序的海侵体系域和早期高水位体系域中，中薄层隐晶质泥晶灰岩和灰黑色薄层泥灰岩组成若干潮下型米级旋回；而在隐晶质泥晶灰岩层面上，普遍发育各种奇形怪状的沉积构造。

The documents include nine VC ++ programming examples of FOSS, including Hough transform, gray balan...

该文件包括9个VC＋＋编程的例子源码，包括Hough变换，灰度均衡，灰度拉伸，图像的3D灰度显示，拉普拉斯高斯边缘检测等等。

For example, to CaSiO〓, wallastonite and cyclowallastonite could be found simultaneously in glazes between the temperature range of 1125℃±10℃, only wallastonite came out below the range, and only cyclowallastonite appeared above the range. Similarly, melilite structure and clinopyroxene structure connected with crystallization temperature. Usually, higher crystallization temperature contributes to forming melilite with simple structure and lower crystallization temperature contributes to clinopyroxene with complex structure.

如钙的偏硅酸盐，硅灰石、环硅灰石的转变温度区域为1125℃±10℃，组分适当的特定釉熔体，高于此温度出现环硅灰石，低于此温度出现硅灰石晶体结构；同样的，黄长石、辉石的出现也与温度有密切的联系，通常，晶体生长的温度较高有利于晶体结构简单的黄长石出现，晶体生长时温度较低有利于稍复杂的辉石结构的出现。

The land is grizzly-bear territory; he hedges that risk with the revolver holstered at his hip, but he has never had to shoot a bear.

该地区是灰熊经常出没的地区，为了抵御灰熊的袭击，舍伦德特意在腰间配备了一把转轮手枪，不过至今还没有机会射杀一只灰熊。

The investigations in this thesis focus on several aspects as follows: We investigate the method that how to produce permutation matrix by using chaotic map, and get the method of image permutation based on chaotic map. This method can make original image to unorderly image to protect the true content of image. We investigate gray level mix function, and put forward a gray level mix function based on chaotic map. Because this function has chaotic characteristics, the image dealed with this function has very uniform histogram. Aiming at the contradiction between error robust and security on image encryption, we put forward a kind of gray level mix function including diffusion mechanism.

本文的研究工作主要集中在以下几方面：研究了如何利用混沌映射产生置乱矩阵的方法，给出了基于混沌的数字图像置乱方法，该方法能够将原始图像变成面目全非的杂乱图像，从而保护了数字图像的真实内容；研究了灰级混合函数，提出了基于混沌的灰级混合函数，由于该函数具有混沌特性，所以经过该函数处理后的图像具有非常均衡的灰级直方图；针对图像加密的错误鲁棒性与安全性之间的矛盾，提出了一种含有扩散机制的灰级混合函数。

Different parts of twenty dominant plant species in five plantation communities on the subtropical hilly lands in Heshan of Gunagdong as well as the litters from three of the five plantation communities were sampled, and their gross caloric value and ash content were measured by using a PARR-1281 oxygen bomb calorimeter and a muffle furnace.

从广东鹤山南亚热带丘陵5种人工林群落中采集20种主要植物器官及3种群落凋落叶样品，利用PARR-1281氧弹热量计和马福炉分别测定样品的干质量热值和灰分含量，再计算去灰分热值；按器官、个体和生长型等比较分析植物的热值和灰分特征。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
