It is found that water velocity vertical distribution under ice-cover is influenced mainly by the relative size of channel roughness and ice-cover roughness, less by the water depth and not sensitive to the variation of Reynold number as well, which is relatively uniform in the flow core and deviates from the logarithmic law.

结果表明：冰盖下水流流速垂向分布主要受床面与冰盖粗糙度的相对大小影响，受水深影响较小，对雷诺数变化并不敏感；在流动核心部分分布较为均匀，并不遵循对数分布规律。

In this paper mainly predictive expressions for porous materials are described.The thermal conductivities of rock wool and calcium silicate insulating materials havebeen calculated by these expressions,however,it has been found that there is somedeviation of calculated values from measured data for these insulating materialscontaining structural water.The effect of the structural water on thermal conductivityhas been studied by means of TG-DTA curves of rock wool and calcium silicateinsulating materials,and...

本文介绍了预测多孔材料导热系数的主要计算方程，通过岩棉保温材料和微孔硅酸钙保温材料导热系数的预测，指出这些方法在预测含有结构水的微孔硅酸钙保温材料导热系数时，与实测值会有较大的偏差，进而利用岩棉和微孔硅酸钙保温材料热重和差热曲线，研究了材料结构水对其导热系数的影响，提出了预测含有结构水的多孔材料导热系数的修正方法，其结果与实测值相当吻合。

摘要在给出水泥胶砂名义水灰比和标准砂平均浆体厚度计算方法的基础上，采用人工神经网络方法，建立了水泥胶砂流动度与水泥胶砂名义水灰比、标准砂平均浆体厚度、粉煤灰与胶凝材料用量比之间的非线性映射关系。

As the plain sand gravel layer porosity and large, so rich in underground water, the total reserves of more than 14 billion cubic meters, in order to bury shallow, varying from small, water stable, easy extraction, mining Degree is low, characterized by good water quality.

由于平原地区砂卵砾石层孔隙度大，故地下水丰富，总储量超过140亿立方米，以埋藏浅、变幅小、水量稳定、开采方便、矿化度低、水质好为特点。

The paper analyses the present situation of seconde songhuajiang river basin water resources artificial control based on the introduction of watershed water resources system controlled by artificial groundwater storage, puts forward some important artificial storage systems accouding to hydrogeological characteristics, analyses separately water volume balance storage model and benefit.

本文在简要介绍了地下水人工调蓄对流域水资源系统的控制的基础上，对第二松花江流域水资源人工控制的现状进行了分析，根据流域水文地质特征，提出了几个重要的人工调蓄系统，并分别对各系统进行水量平衡、调蓄模式和效益分析，从而得出用地下水人工调蓄对二松流域水资源系统进行控制是可行的结论。

By comparing the landslide displacement and the shearing strain increment under different water level condition, discovered that along with the rising water level, the displacement and the shearing strain increment of Taping landslide are obviously increased, it is show that the landslide has the obvious response to the storage, the water rise cause the stability of landslide present the reduction tendency.

通过不同水位状态下滑坡位移和剪应变增量的分析，发现，随着水位的上升，塔坪滑坡的位移及剪应变增量都明显增大，说明滑坡对蓄水有明显的响应，水位上升使滑坡的稳定性有降低的趋势。

This paper presents mutagenic activity and organic pollutants, in which one raw water of drinking and normal process treated water are tested by Ames measure and analysed by chro-matography and mass spectrography.

通过对某饮用水源及经传统工艺处理的出水进行Ames试验及色谱—质谱联机分析，本文提出了两种水质的致突变性及水中所含有的有机污染物成份。

Shortly after the 1931 competition, an R engine using a special fuel blend powered the winning Supermarine S.6B aircraft to a new airspeed record of over 400 miles per hour (640 km/h). Continuing through the 1930s, both new and used R engines were used to achieve various land and water speed records by such racing personalities as Sir Henry Segrave, Sir Malcolm Campbell, and his son Donald; the last record was set in 1939.A 1951 R-powered water speed record attempt by Donald Campbell was unsuccessful.

在1931年比赛后不久，一台"R"发动机在使用一种特别的混合燃料做动力的情况下，使得一架获胜的休泼马林公司的S.6B飞机飞出了超过400英里1小时(640 km/h)的新记录，在随后的30年代里，崭新的和使用过的"R"发动机在亨利·西格雷夫，坎贝尔·马尔科姆爵士及他的儿子唐纳德·马尔科姆这些竞赛名人的手中创造了一系列的陆地及水面速度记录，最好记录于1939年创造，1951年唐纳德·马尔科姆尝试刷新R发动机载动的水上速度记录但没有成功。
