The analysis of corrosion performance of car bodies coated by no nickel and low nickel zinc phosphating processes

In today's automotive industry in order to protect car bodies from corrosion, spray or immersion type zinc phosphating processes are applied. In both types, nickel and chromium are widely used though they are harmful to human health and environment. In this study, car body's corrosion performance, coated by no nickel (0 ppm) and low nickel (100, 200, 300 ppm) immersion type zinc phosphating (without chromium passivation) processes, are compared to the bodies that are coated by spray and immersion type processes including nickel (500–700 ppm) and chromium. After analyzing coating weight, composition, morphology of the crystals and salt spray test corrosion performance of car bodies specimens coated by no nickel and low nickel processes are as good as the ones coated by spray and immersion phosphating processes including nickel and chromium. In developing environment consciousness, it is inevitable to favor no nickel or low nickel processes since they give no harm to nature and human health.

东濮凹陷地质特征研究

岩心观察及精细的层序地层对比表明,东濮凹陷北部沙三段的盐岩与暗色泥岩、膏泥岩及砂岩具有共生组合关系,盐岩是低水位期的沉积。在高水位期,盆缘沉积了三角洲和扇三角洲,盆内沉积了深灰色泥岩和少量重力流砂体;在低水位期,湖盆面积缩小,许多地区暴露地表,从湖泊中心向周围沉积物依次为盐岩、膏岩、膏泥岩、碳酸盐岩、灰质泥岩和牵引流砂岩体。高水位和低水位的频繁变化导致深水暗色泥岩和低位盐、低位砂的纵向叠加。通过对高频振荡湖盆的古地理环境以及盐岩与砂体分布、盐岩分布与沉积中心的关系的研究,得出与以前"深水成盐"、"高山深盆"、"浊积成砂"等不同的新概念,对确定盆地油气资源潜力和勘探方向有一定借鉴作用。

严重椒盐噪声污染图像的非线性滤波算法

针对灰度图像的椒盐噪声滤波问题，提出一种保细节的非线性滤波算法。利用局部统计信息，首先将图像像素点粗分为信号点、可能的正噪声点和可能的负噪声点3类，建立噪声标矩阵；然后再根据噪声标记矩阵的局部统计信息，将可能的噪声点细分为信号点、噪声点和不确定点3种类别，并分别采用不同的方法进行滤波，以保留更多的图像细节。结果表明，本文算法在去噪能力、自适应性以及保留细节等方面都明显比其它4种算法强，尤其是对于噪声高度污染图像的情况。     

Studying the mechanism of acoustic emission in failure of rock salt by dissolving

The laboratory-scale plant, procedure and test results are presented for the experimental failure of rock salt specimens by dissolving. It is established that dissolving proceeds irregularly in time and has three stages. This fact is confirmed by different standard deviates of the dissolving rates, acoustic emission activity behavior and its signal spectra recorded at each stage. __________ Translated from Fiziko-Tekhnicheskie Problemy Razrabotki Poleznykh Iskopaemykh, No. 1, pp. 39–48, January–February, 2006.
