含水氯化物体系中金和银的相对溶解度测定

文章叙述了用Ａｕ－Ａｇ合金测定Ａｕ和Ａｇ溶解度及讨论Ａｕ的热液行为的意义和方法。实验结果指出：在３００℃，ｆｏ２在１０＾－３５￣１０＾１４间，ΣＣ１＝３．０ｍｏｌ／ｋｇ和有含银矿物存在时，Ａｕ－Ａｇ系列与含水氯化物热液反应，Ａｕ－Ａｇ系列中纯Ａｕ的溶解度最高，中间组分的溶解度随ＸＡｕ的增加而升高，而银的溶解度随ＸＡｇ的变化不明显，但随ΣＣ１＾－浓度的增加而升高，在含银相存在时，金和银总是趋向于形成     

On estimating a relative safety loading for structures

This paper considers the reliability of a structure for earthquake load assuming that the number of earthquakes over a period [0, T] follows a truncated non-homogeneous Poisson process. It models the damage distribution along the line of a mixture of two distributions and derives an expression for the failure probability. It also estimates the value of a ‘relative safety loading’ that makes the failure probability as zero and investigates its asymptotic properties both theoretically and numerically.     

滇西澜沧变质带中白云母b_0值特征及其多期变质作用意义

滇西澜沧变质带中199件白云母b_0值分析结果表明,b_0值均在0.9020nm以上。与澜沧变质带遭受蓝片岩相高压变质作用的事实相吻合。此外,白云母b_0值的统计规律显示,澜沧变质带经历了多期变质作用,一期为高压变质作用,另一期为中压变质作用,这也与已知的地质现象相符。由此可见,白云母b_0值可以很好地反映多期变质作用。

本文主要论述了具有叠加性质的吐鲁番中，新生代断隐盆 地中，新构造运动的形迹与地貌显示。指出晚第三纪以来周边山地与盆地底部巨大的断块差异升降运动，乃是深隐盆地形成的关键；盆地中新构造运动形迹十分明显，地貌表现普遍而突出。     

一种基于图像统计量的相对辐射纠正算法

线阵推扫式传感器，由于在信号传输和转换以及量化过程中产生的奇偶效应，和不同CCD探元的响应差异，导致原始图像出现明显的纵向条纹，相对辐射纠正的目的就是降低或者消除这些影响，以恢复图像原始信息。针对宽幅线阵推扫式传感器的特点，提出了一种基于图像自身统计量的相对辐射纠正算法——相邻列均衡法，消除了原始图像中明显的纵向条带效应。和常规的基于图像统计量的相对辐射纠正算法相比，这种算法的特点在于求解相对辐射定标系数时不依赖于均匀场景，并在处理北京一号小卫星图像中得到了验证。     

Experience of Vibrocompaction in Calcareous Sand of UAE

The study is concerned with the influence of various factors on vibro compaction in calcareous soils, This include effect of carbonate content, and influence of pore water pressures in sand, settlements during vibrocompaction, vibroaccelerations during sand column installation compared to earthquake accelerations and finally the liquefaction design based on average CPT parameters. Previous experiences with calcareous sands and literature review confirm the necessity to apply a correlation factor for calcareous material to the raw cone penetration resistance CPT values obtained in the field. Because of the very fragile grains of the Dubai calcareous sands the penetration resistance will be influenced by crushing and grinding. To accommodate for effect of calcareous sands on measured CPT values, a best fit correlations formula called here “correlation factor” is developed. A parametric dynamic triaxial liquefaction testing programme has been executed on representative samples with loose and dense zones. Representative testing parameters for field conditions and earthquake design accelerations have been applied indicating that ground improvement is necessary. It was observed during the dynamic triaxial tests that the whole soil mass consisting of dense columns and looser zones in between behaves jointly, and therefore compaction control using an average-CPT approach is possible.
