This experiment aims at investigating the influence of the form size and colour of geometric diagrams upon the criteria of classification in children of 3-9.Here four diagrams of different forms, sizes and colours are presented. Results show that children of less than 5 lay stress on colour and those older than 6 lay stress on form and size in their classification. As the age grows, fewer children depend on colour for classification and more on form.Two years, however,are necessary for an obvious change in classifying...

This experiment aims at investigating the influence of the form size and colour of geometric diagrams upon the criteria of classification in children of 3-9.Here four diagrams of different forms, sizes and colours are presented. Results show that children of less than 5 lay stress on colour and those older than 6 lay stress on form and size in their classification. As the age grows, fewer children depend on colour for classification and more on form.Two years, however,are necessary for an obvious change in classifying ability.Varlation in colour, form and size of the diagrams also influences the choice of the criteria of clas-sification,but the influence of colour is explicit while that of form and size is implicit.

本实验用不同颜色和大小的四种几何图形让3—9岁儿童分类,研究年龄及图形颜色、大小的变式对选择分类标准的影响。结果发现:5岁以前按色分类为主,6岁以后按形分类为主。随着年龄增长,按色分类的人次逐渐减少,按形分类的人次逐渐增加。不过,要经过两年,分类能力才发生一次显著的变化。图形颜色、大小的变式也影响分类标准的选择,但颜色的影响是显著的,大小的影响是潜在的。

Effects of the stress or strain conditions on the shearing strength of geologic media by the conventional triaxial tests are discussed. And then the selected failure points on the stress-strain curves by these triaxia! tests are clarified. The results indicate that two standards of failure, de-viator strees and stress ratio, in the triaxial drained tests are identical, i, e., the maximum deviator stress and stress ratio met at the same strain. But the maximum deviator stress in consolidated undrained test or...

Effects of the stress or strain conditions on the shearing strength of geologic media by the conventional triaxial tests are discussed. And then the selected failure points on the stress-strain curves by these triaxia! tests are clarified. The results indicate that two standards of failure, de-viator strees and stress ratio, in the triaxial drained tests are identical, i, e., the maximum deviator stress and stress ratio met at the same strain. But the maximum deviator stress in consolidated undrained test or undrained test occurred before or after maximum stess ratio or at the same strain. Two failure standards for consolidated undrained test or undrained test should be used at the same time, but their lower values are selected for compulations of practical engineering problems. In the adoption of design shear strength, the mobilized shear strength and two-dimensional extent of fissure should be considered and utilized.

本文讨论了常用三轴压缩试验中应力应变条件对抗剪强度的影响,又讨论了常用三轴压缩试验中破坏标准的选择。在常用三轴排水压缩试验中应力差和应力比两种基本破坏标准是一致的,即应力差最大值与应力比最大值在同一应变时达到。在固结不排水压缩试验中应力差最大值出现在应力比最大值之前、之后或在同一应变处。故在固结不排水或不排水试验中,两种破坏标准应同时采用,取其低值,用于实际工程计算,关于设计指标的选用,应考虑强度的发挥度或工作应力,裂隙岩石的设计指标选择,应考虑二维连通比。

Since the environmental ecological equilibrium has been destroyed, it is inevitable to value the environment. This article introduces comprehensively the environmental appraisal of the forest soil in Nancha of Heilongjiang Province. It also discusses a series of questions deaing with characteristics of the forest soil environment, the distribution of sample taking, soil sample analysis, the choice making of evaluation standards, the evaluation model, the relations between soil grades and so on.The study also makes a successful evaluation about the polluted levels of copper, zinc, lead, cadmium, chromium, mercury,arsenic and the toxic metals in soil, whose results are satisfied.We have taken the way by which grid distribing was combined with snake-shape distribing. After the soil sample was processed, we take measures in all cases with atomic absorption spectrophotometer and give the lowest detecting limit of each element.While calculating of the comprehensive index, Nemeioul Index is used, which pays more attention to the effect of the heavily polluted pollutants. Since there is no unanimous standard to set an evaluating standard, it is easy and practical to measure the metal content in the contrasted soil and precise degree of pollution can be obtained.

林区环境生态平衡遭到破坏,环境的质量评价势待必行。本文全面介绍了黑龙江省南岔林区土壤环境评价。针对环境的特点,对采样点的分布,采样方法,土样分析,评价标准的选择,评价模式的应用及土壤等级的划分等一系列问题进行了探索。力图使环境评价这一基础性工作尽快程序化,模式化和标准化。对土壤中铜、锌、铅、镉、铬、汞、砷等几种有毒金属污染物进行了评价,获得了满意的结果。 采用了网格法和蛇形法相结合的布点方法土样经予处理后,用原子吸收分光光度计测定并给出了各元素的最低检出限。评价方法采用污染指数这一数学模式。综合指数的计算采用内莫罗综合指数法,突出考虑了污染较重的污染物的作用。关于评价标准的确定,在目前尚无统一标准的情况下,选择土壤对照点中金属元素的含量作为评价标准,简单易行,结果也能较好的反应污染程度。
