The experimental results show the validness of the mechanism analyses.2. According to the generation mechanism of the leak acoustic signal, the characteristics of the leak acoustic signal are investigated. The auto correlation technology is adopted to descript the leak signal characteristics due to the ability to analyze the coherence of time series. A new procedure to identify the leak acoustic signal from the disturbed noises is proposed based on the conjunction of correlation and approximate entropy algorithm.3. The principle and application in leak location of the correlation and the adaptive filter techniques are introduced. The problems of the traditional leak location methods are analyzed.4. In order to establish the leak detection signal model, the leak acoustic propagation characteristics are investigated experimentally.

从泄漏声产生机理出发，分析了管道泄漏处湍流拟序结构与空泡间相互作用的机理，认为在该机理作用下，泄漏声信号产生过程具有&不可重复&的特征；由于相关函数具有分析时间序列拟序结构的能力，且近似熵从统计的角度区别时间过程的复杂性，因此，提出将信号相关分析和近似熵理论相结合的方法，提取泄漏声信号&不可重复&的特征，辨识管道泄漏故障发生；在实际检测现场，由于各种管内和管外固定声源噪声(如阀门噪声、工地施工噪声等)常导致泄漏误判和漏点定位错误，重点分析了管内固定噪声源的产生机理和特征，为复杂干扰环境下的泄漏辨识提供理论支持。

In the very season the green birds of South River don't spread the letters outside cloud, but we could see that "an oriole warbled from within the flowery branches."

This devise is a pair of reformed chopsticks,which could economize efforts and adds more efficiency through the ribs shape of design at the botton to have more contact faces and points between chopsticks and foodstuffs. It is easy to clip tiny or slippery foodstuffs just like noodles, beans or eggs. On the other hand, this reformed chopsticks is more convenient than the traditional one which is in a pole shape or have concaves on it. The reformed one need not adjust the concave side to cilp foodstuffs.

本创作是一种更省力且使用更方便的改良快子，藉由筷子夹持端之肋条状设计，增加筷子与食物间之接触面积与接触点，对於夹取面条、豆类或卤蛋等外径、体积细小或表面圆滑之食物甚为方便有效，相较於传统圆杆状或表面设有内凹沟槽之筷子，本筷子不仅夹持力更佳，使用时更不需刻意调整设有内凹沟槽之部位来夹持食物，使用上更为方便省力。

The results demonstrated that laurocapram disrupts the highly ordered lipid structure of stratum comeum and makes the structurs of SC loose,which causes the outermost cell of SC easy to exfoliate and decreases the barrier function of skin for the transdermal absorption of drug;Meawhile, laurocapram penetrating into the intracellular matrix of SC cells fluidizes the filaggrin matrix protein and swells the dermal SC, which could increase the free volume of drug and water content in the SC.

探讨氧酮促进洛美沙星透皮吸收的作用机理。结果表明，氮酮通过以下途径促进药物透皮吸收：（1）作用于表皮角质层细胞间脂质。使角质层变得疏松。细胞间距增大。外角质层细胞易于脱落。降低了皮肤对药物的屏障作用；（2）氮酮进入角质细胞内。与细胞内基质相作用。引起基底角质层肿胀。
