发现Zn元素在几种污泥中的不稳定形态均较高，在污泥农林利用过程中容易被植物吸收利用；Cu元素主要以稳定的有机结合态和残渣态存在于各种污泥中，稳定性较好，在污泥农用过程中不易释放到环境中；Ni元素在几种污泥样品中，稳定态与不稳定形态的比例较为相近。

The detection results of traditional edge detection method are fuzzing and sensitive to noise for convolution operation,and the detection results of morphological edge detection method are easy to lose edge information for various detection results.

针对传统的边缘检测方法因卷积运算造成模糊图像边缘，且对噪声敏感，各种形态学边缘检测方法因检测到的边缘信息类型不同而容易使边缘信息丢失，提出一种组合式抗噪型形态学边缘检测算子；并利用不同尺度的结构元素具有不同的图像边缘检测效果，进行形态结构元素的尺度调整，得到不同尺度结构元素下的图像边缘位置；然后进行加权合成来获得边缘图像；实验表明，与其他的传统或者形态学边缘检测方法相比，该文方法不仅具有更好的噪声抑制功能，而且其检测到的边缘轮廓更加清晰完整，边缘细节更加丰富。

Not only is it successive to the SCEZ economy in system, but also it continually provides environmental support in the forms of Communist talents and Communist elements for the SCEZ in its own development and growth and percolates Communist economic elements into the capitalist market, becoming the nutrition for the development and growth of the SCEZ and its protector.

共产企业经济是共产特区经济的有益补充，是资本市场中的共产经济元素，不仅从体系上与共产特区经济一脉相承，而且在自身的发展壮大中，不断向共产特区经济提供共产人才和共产元素的环境支持，在资本市场中不断渗入共产经济元素，成为共产特区经济不断发展壮大的生存营养和护法使者。

The Communist enterprise economy is a beneficial supplement to the SCEZ economy and is a Communist economic element in the capitalist market. Not only is it successive to the SCEZ economy in system, but also, in its own development and growth, it continually provides environmental support in the formsof Communist talents and Communist elements for the SCEZ and percolates Communist economic elements into the capitalist market, becoming the nutrition for the development and growth of the SCEZ and its protector.

共产企业经济是共产特区经济的有益补充，是资本市场中的共产经济元素，不仅从体系上与共产特区经济一脉相承，而且在自身的发展壮大中，不断向共产特区经济提供共产人才和共产元素的环境支持，在资本市场中不断渗入共产经济元素，成为共产特区经济不断发展壮大的生存营养和护法使者。

This thesis gains the construction form of xi"an street facility from reflexing on the current street facility, taking xi"an for example, combining traditional elements and city street facility, surveying and analyzing the circumstance of xi"an city"s traditional elements and the form of street facility.

本论文从对当前街道设施问题的反思入手，以西安为例，将传统元素与城市街道设施结合起来，通过对西安城市传统元素与街道设施形式结合的现状调查分析，以及对传统元素与现代生活关系正确认识的比较研究中得出具有历史文化背景的西安街道设施的建设形式。

Based on the simulation data, the effects of clearances, damping coefficient and the rotation speed on the dynamic behaviors are studied: compared with ideal mechanisms, mechanisms with clearances are less stable; as for mechanisms with clearances, when the crank rotates at the speed of 100rad/s, the actual clearances are always above the radium of clearances, axle pin and axle cover keep contact throught the rotation; when the crank rotates at the speed of 20rad/s, mechanisms are in an unstable state, at an angle of about 300, the actual clearances are below the radium of clearances, pairs lose contact, which results in collision between them; with the speed of 20rad/s, when damping coefficient is assumed 175Ns/m, distinct separation and collision happen between pairs; when damping coefficient is assumed 220Ns/m, separation and collision are controlled.

在含间隙机构中，当曲柄以100rad/s转动时，运动副间隙始终大於半径间隙，轴销与轴套始终保持连续接触；当曲柄以低速20rad/s转动时，系统处於极不稳定的震荡状态，在转至300°左右时，运动副间隙小於半径间隙，脱离接触，发生明显的分离碰撞现象。在含间隙机构中，曲柄以低速20rad/s转动，当取法向阻尼系数为175Ns/m时，副元素发生明显的分离碰撞现象；当取法向阻尼系数为220Ns/m时控制了副元素的分离，副元素一直处於连续接触状态。

In the research area , To study the correlation between heavy metal elementss indicates that, between the heavy metal elements, the heavy metal and other elementss have the co-function and the anti- function, and this strengthen the corn to bear the heavy metal the ability Possibly.
