( 2 ) according to national building mortar design regulations ( nbmdr ) , and applying to scientific avenue of orthogonal design experiment , performance and impact factors of dry - mortar produced by localizable phosphor slag , flying - ash , ordinary silicate cement , and yellow sand ( 2 )根据国家建筑砂浆设计规程,应用正交试验分析等科学方法,试验研究了用本地磷渣、粉煤灰、普通硅酸盐水泥、黄砂等原料配制的干拌砂浆性能及其影响因素。
Based on the analysis of the data and information from the field observations and lab experiments , the results were as follows : ( 1 ) the results of the simulated rainfall and runoff erosion experiments in lab . under the design experiment conditions including the constant rainfall intensities of 1 . 0 , 2 . 0 , 3 . 0mm / min and the rainfall durations of 30 , 70 minutes and with soil moisture content 9 . 5 % or 10 . 0 % for dry situation , as well as with the soil moisture content 19 . 0 % or 20 . 0 % for wet situation , the soil erosion increased nonlinearly with the rainfall intensity , and the rainfall duration . the results of the experiments indicated that the amount of soil erosion caused by the simulated rainfall and runoff on the dry - soil slope was more than that on the wet - soil slope 通过实地观测及室内试验资料分析,得到如下研究成果: 1 、室内模拟降雨径流对戗坡的侵蚀试验研究结果在定雨强为1 . 0 、 2 . 0 、 3 . 0mm min ,降雨历时30 、 70分钟,干土含水量为9 . 5 10 . 0 ,湿土含水量为19 . 0 20 . 0的条件下,侵蚀量与雨强成非线性正比关系;雨强大,侵蚀量大;降雨历时长,侵蚀量也大;堤坡含水量大时,侵蚀量小,堤坡含水量小时侵蚀量大。
With self - designed experiment as its basis , basic medical college of shanghai jiao tong university has made teaching reform that is design - oriented and integrative with intent to cultivate students ' innovation consciousness and practice ability . as a result , a teaching model of " research - based learning " , which aims at bringing forth innovative talents , has been constructed and produced desired effects 上海交通大学基础医学院以自行设计实验为载体,进行设计性综合性实验教学改革,着力培养学生创新精神和实践能力,初步构建出了“探究为基础”的教学模式,培养创新人才,并取得了一定的成效。
The main contents are as follows : in order to finish this work well , the author collected the basic parameters of water cushion in china and foreign countries , and analyzed the questions and shortcoming in the designing of cushion in domestic and abroad , and summarized the design experiment of xiao wan hydraulic power station and ertan hydraulic power station in china , finally the main controlling design parameters of baishan water cushion , that is the allow dynamic impact water pressure and unit water consumed energy rate were asserted 具体内容如下:为了做好白山水垫塘设计,本文通过收集国内外水垫塘设计的基本参数,分析水垫塘设计存在的问题及不足,总结国内小湾、二滩工程的经验,确定白山水垫塘设计主要控制参数即允许动水冲击压力及水垫塘单位水体消能率。
To design the water cushion of baishan arc dam , the design experiment of ertan hydraulic power station , xiao wan hydraulic power station were refereed . through large amount of scientific experiments and theoretical calculation , and the design coefficients of water cushion in domestic and abroad were summarized , then the design layout of the baishan cushion was worked out at last 本文针对白山拱坝水垫塘方案设计,参考国内二滩、小湾等工程设计经验,通过大量的科学试验和理论计算,总结国内外的水垫塘设计参数,最后确定了白山水垫塘的设计方案。
