Wear and corrosion involve mechanical and electrochemical mechanisms, and the combined action of these mechanisms often result in significant mutual reinforcement. To measure the effect on wear-corrosion resistance of the chemical and abrasion wear separately at the same time, wear-corrosion synergism rate is selected to indicate the nature and degree of the chemical and abrasion wear.

腐蚀磨损是同时涉及力学因素和电化学因素的复杂的材料的流失过程，通常条件下，腐蚀磨损不是纯磨损和纯腐蚀的简单叠加，还有两者间的协同作用，为定量描述腐蚀与磨损的促进程度、进一步完善腐蚀磨损机理，本文利用腐蚀磨损协同作用率值的大小来分析腐蚀和磨损的交互作用程度，结果表明：本文制备的镀层，在5％H_2SO_4溶液中腐蚀磨损时，机械磨损是造成镀层表面材料流失的主要原因，腐蚀和磨损的协同作用为次要因素。

When the instrumental value of learning educational theories is emphasized,its meaning of life is hidden in teacher development,so as to break educational theories and teacher development in the aspect of life.Analyzed from the perspective of teacher's life,teacher development implies much meaning of life and educational theories should care for life in many ways.

一、教育理论和教师发展在生命层面上的断裂教师发展中生命创造的缺失在学校研究性变革实践中，教师需要学习全新的教育理论、思维方式去应对、反省复杂的教育情境，改变自身在学校生活中的生存方式，实现自己在课堂教学中的生命创造，因为教师发展不能局限于专业发展。

Integrity has been kind-hearted Dr. Ma Naite persecution, beautiful Lucy gentle, elegant noble Charles, honest Loury, the appearance of indifference, his enthusiasm, and selfless bohemian noble Sidney, distorted human DEFA Qi wife, Bold普洛士loyal Miss, cruel insidious ......埃佛瑞蒙brother complex tangled up of hate, cruel revenge created more hatred, love the edge of hell renewable, but is based on the cost of life .

正直善良却惨遭迫害的马奈特医生，美丽温柔的露西，优雅高尚的查尔斯，忠厚老实的洛瑞，外表冷漠、内心热情，放荡不羁而又无私崇高的西德尼，扭曲了人性的德发奇太太，豪爽忠诚的普洛士小姐，残忍阴险的埃佛瑞蒙兄弟……复杂的仇恨纠缠不清，残忍的复仇制造了更多仇恨，爱在地狱的边缘再生，却是以生命为代价。

However, methods and references for difference equation are relatively less. The new method proposed in this paper transfer the complex boundary value problem into the existence and uniqueness of the solution of the linear equations. For linear case , we obtained the necessary and sufficient conditions for the existence and uniqueness of the solution for the BVP; For the nonlinear case ,we got a series of new sufficient conditions by using contraction mapping theory and cone theory .

而差分方程边值问题的研究方法和文献还很少，文中新的研究差分方程边值问题的方法是将复杂的边值问题求解转化为代数理论中的线性方程组解的存在和存在唯一问题；对线性情形，较容易地获得了边值问题的解存在以及唯一的充分必要条件，而对非线性情形，则通过压缩原理和锥理论等各种不动点定理，获得了一系列新的充分条件。

With the limitation of the line detection based on traditional Hough transform that the information of the length and the end points of the line is unavailable, a new algorithm which makes use of the accessional strategy based on precognition information is put forward to meet the demand for more information of the line, simulation results show this method is effective. Finally, the whole process of airport target recognition is presented and the result images are also given.

使用分形方法提取目标的特征，在知识指导下，提出了一种基于目标特征模型的降维的形态学分形维数计算方法，对传统分形方法进行了改进，从理论上推证了算法的合理性，并对算法进行了仿真分析；针对传统Hough变换无法获得线段端点和长度信息的局限性，提出了一种基于目标特征先验知识的Hough变换融合策略，通过引入目标先验知识，可以有效地获得直线信息；对信息多而复杂的机场目标采用基于知识的目标识别方法，使用置信度模摘要型实现不确定推理，对目标进行识别判断，将知识贯穿于整个识别过程中，对目标进行了有效地识别。

The goal of this paper is to recognize the boundaries of prepositional phrases automatically without introducing parsing technique.

本文研究的目标是：在不引进复杂的句法分析的前提下实现介词短语边界的自动识别，期望其作为句法分析预处理的一部分为句法分析提供一定的帮助。

But the applicable range of those methods are usually limited and the cutting lines suggested by those methods usually have the arbitrarily curved shapes and it is not desirable to introduce such complicated cutting lines to garment patterns because of the limitations not only in the design but also in the producibility of the garment.

但是那些方法的可适用的范围通常是有限的，并且那些方法建议的插队通常有任意地弯曲的形状，并且介绍这样复杂的插队给服装样式由于局限不仅在设计，而且在服装的可生产是不中意的。

In Nabokov's thought, aesthetic excitation isn't a pure concept, but a complex feeling. It is not only sensuous, but also rational; not only the excitation of the writer in the process of writing, but also the shock of the readers in their resonance with the writer; not only aesthetic, but also showing appreciation of the ugliness.

论文指出在纳博科夫这里，审美狂喜不是一个单纯的概念，而是一种复杂的感受，它是感官的，也是理智的；是作家写作时的亢奋，也是读者共鸣时的震颤；是审美的，同时也是审丑的。

Based on traditional balanced cross section in pure geometry, we put forward a method of physical balanced cross section that has two basic principles: normal direction conservation and deform matching.

作者在纯几何学方法的平衡剖面技术的基础上，着重考虑了岩石变形的物理规律，并根据岩石变形机理和物质守恒原理，提出了以法线不变原则和变形匹配原则为基础的物理平衡剖面法，实现了复杂的原始地质构造剖面的自动化恢复。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
