The contourlet transform used in the system was constructed by dual tree complex wavelet transform followed by critically subsampled directional filter banks, sub-bands energy and standard deviations were cascaded to form feature vectors, and the similarity metric was Canberra distance. The performance of retrieval system was compared including original contourlet transform, non-subsampled contourlet transform, semi-subsampled contourlet transform and CCT under the same system structure.

该系统采用的复数轮廓波变换由双树复小波变换级联临界下采样方向滤波器构成，特征向量采用子带系数的能量和标准偏差连接而成，以Canberra距离为相似度度量标准；比较了基于同样架构的基本轮廓波变换、无下采样轮廓波变换、半下采样轮廓波变换和CCT纹理检索系统的性能。

But some of those systems adopt one layer DDC structure that is unreliable and badly expansible, and can't satisfy the requirement of general management and hierarchy management in fermentation process.

但在这些实现的系统中，有很大一部分采取单级的直接数字控制系统结构，可靠性和可扩展性都比较差，很难满足对全厂的发酵过程进行全局管理和分级管理的需要。

To investigate vertical competition in the two-echelon serial supply chain, a M/M/1 queue model is established, the efficiency, firms'decision variables and the customer service level between centralized and decentralized control are compared; a supply chain horizontal competition model is established, the impacts of horizontal competition on performance of the supply chain are analyzed by using theoretical and numerical methods.

针对两级串联供应链中的垂直竞争问题，建立了M／M／1排队模型，对集中控制与分散控制下，供应链的效率、厂商的决策变量和用户服务水平进行了比较分析；建立了供应链水平竞争模型，采用理论分析和数值计算方法，研究了水平竞争对供应链绩效的影响。

In order to get the optimal noisy matching,analyzed and compared inside resistance and noise characteristics of bipolar junction transistor、integrated operation amplifier and junction field-effect transistorand the characteristics of three coupled modes.

为了达到最佳噪声匹配，分析比较了双极型晶体管、集成运放及场效应管的内阻、噪声特性及三种不同耦合方式的特点，从而总结出对于低内阻信号源较理想的前置放大器的有源器件是单级或多级并联双极型晶体管。

End, I generalize me to educate the technical comprehension to the modern with a more weak-minded language:The modern education technique is the most advanced teaching method, is the teaching technique that a kind of grade arrives the cremated ashes class already.

最后，我用一句比较弱智的语言来概括我对现代教育技术的理解：现代教育技术是最前卫的教学方法，是一种等级已达到骨灰级的教学技术。

According to this analysis, a new pixel-level fusion algorithm based on the activity and similarity of source images is proposed and its performance is tested to be superior to the congeneric algorithms.

在以上分析的基础之上，作者提出了一种基于源图象活跃度和相似度的像素级融合算法，经过实验比较证明该算法的融合结果质量较同类算法有大幅度的提高。

objective:with the local lobster shell as the raw material,we inquire into the abstraction and preparation of chitin and chitosan to develop a new raw material resources for chitosan.methods:use methods such as take off protein,calcium,colour,deacetylate and purification to prepare chitosan to study deacetylate degree,molecular weight and other characters of chitosan,then compare with infrared spectrum of bio-chemical chitosan on market.results:the chitin and chitosan obtained from lobster shell are 14.8% and 8.9%, respectively.

目的：以地产龙虾壳为原料，探讨其甲壳素的提取和壳聚糖的制备方法，以开发壳聚糖制备的新原料资源。方法：用脱蛋白、除钙、脱色、脱乙酰基、纯化等方法制备壳聚糖，研究其壳聚糖的脱乙酰度、分子量等性质，并与市售生化级壳聚糖的红外光谱进行比较。

Comparisons show that there is no correlation between the experimental sensitivity of tetrazole compounds and various previously proposed theoretical static criteria, such as the bond length and bond order of relevant bonds, net atomic charges and electronegativity and the content of 2H-teterazole isomers in both gaseous and condensed states.

把四唑衍生物的实验感度与前人曾提出过的各种感度理论判据—一些静态结构性质(如相关键的键长、键级、原子电荷和电负性等)以及平衡体系中2H-异构体的含量—进行比较，均未找到它们之间的规律性联系。

Oxidation veratryl alcohol by LAC/NHA or HBT was 0 degree reaction, but the coefficient of the reaction with NHA is bigger than that with HBT, which means that NHA is more efficient for LMS delignification than HBT.

此外，还比较了NHA和HBT作为介体的LMS体系氧化非酚型木素模型化合物藜芦醇的动力学规律，结果表明藜芦醇的氧化与时间呈直线关系，此氧化反应为0级反应，不过使用NHA和HBT作为介体时，藜芦醇的氧化速度常数有所不同，使用NHA时，藜芦醇氧化的速率常数大，反应速度快。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。
