帮忙翻译一段泥沙实验
|
|||
|
实验结束后将水慢慢泄空，待沙样较干后, 进行粗化层取样。将15x15cm的框架沿程布设六至七个，布设厚度为初始床沙级配的2倍中值粒径。(大量试验表明，粗化层厚度为初始床沙的2倍中值粒径)，将适量熔化后石腊均匀倒在框内，待石腊冷却后将框架从床面取出，并将试验沙取出，放人直径10cm 、高为10cm的容器(该容器上下底用0.05mm 孔径的铅丝网、周围用白铁皮做成)，并将吐温80或乳百灵20ml倒人容器内，将容器放人水中，每煮沸20分钟换一次水，一般换4-5次水即可将石腊从试验沙中完全分离出来，且这种分离方法不会改变沙样级配。 [ Last edited by lzjketty on 2011-1-21 at 19:23 ] |

其中吐温80或乳百灵可能为实验药品名称，你自己修改一下英文翻译，翻译可能比较差劲，毕竟不是我的专业，楼主参考吧 **************************************************************** At the end of the experiment emptying the water slowly until the sand simples look dry, then take sampling from the layer .The framework of the 15x15cm is laid six or seven along the way,and the thickness laid is 2 times median diameter of the initial bed material . (A large number of experiments show that the initial coarsening of bed thickness of 2 times the median diameter), amount of melted paraffin poured in box uniformly , removed the frame from the bed after paraffin is cooled , took out the test sand , put it in a diameter 10cm and height 10cm container(The upper and lower of the container is made with 0.05mm diameter lead wire and surrounded by white tin) , poured 20ml(吐温80或乳百灵) into the container and laid it into water ,and boiled for 20 minutes each for water . Generally the paraffin was separated from the test sand after 4-5 times of water replacements and the sepatation didn’t change the grading of sand. |
