而且金属网栅衬层对雷达波屏蔽作用的影响只与衬层材料的面电阻有关,与材料其它因素无关,面电阻越小,网栅的屏蔽效果越好。
The special structure of zippered plastic pipe zippered seep holes made a greater seepage quantity on the condition of bare pipe ( no anti - blocking material adopted at the mouth of seep holes ) . so several kinds of anti - seepage material were adopted in the experiment of this part in order to find the proper anti - seepage material ( nonwoven fabrics glued by neoprene ) and working head ( 3m ' s working herd on initial irrigation )
由于拉链式塑料管的独特构造(拉链式渗水孔口) ，裸管(渗水孔口不采用任何防堵材料)情况下渗流量很大，所以本部分试验采用了几种防渗材料试验，最后通过比较分析，找到了合适的防渗材料(氯汀胶粘无纺布)和工作水头(初始灌水时3m工作水头) 。

硅酸钠被大量地用于制造工业作为填充剂，在金属浇铸中作为砂型粘结剂，版纸工业中被用作胶合剂，在耐火材料行业中用作粘结剂，在电焊条行业也用作粘结剂，在电子工业中可用作显像管成屏的粘结剂，在水处理中用作处理剂，防结垢剂等。在合成洗涤剂行业中用作助剂，在清洗剂行业中用作清洗及防腐缓冲剂，在石油开采中用作防止井喷材料，在矿山开发中用作堵漏材料、矿石浮选剂和泥浆稀释剂等。
In this thesis , first , reasons and factors for the stability of loose rock dams were summarized according to the field surveys and certain expert ' s experiences . then , researches on block stability problems were reviewed , and according to the relationship between grain size and incipient velocity , it is found that the block weight is in direct proportion to 6 - 9 power of incipient velocity , and 50 % increase of the velocity will result in about 40 times change of the block weight . after that , experiments were conducted in a flume , focusing on the relationship between incipient velocity and some main factors including block weight , water depth over the dam , cross - section size , block material and river bed material
本文首先根据散抛石坝损毁情况的现场调查资料，结合有关专家多年的整治经验，总结出坝体的损毁原因及影响因素；对现有块体稳定性的研究成果进行回顾和总结，并针对散抛石坝的直接损毁现象，结合山区河流的水流、地形特点，利用块体粒径与起动流速的关系，提出块体稳定重量与起动流速高次方成正比的概念，流速50的增长可能导致块体稳定重量接近40倍的变化；通过二维变坡水槽试验，研究了坝体稳定的主要影响因素，包括块体重量、坝顶水深、断面尺寸、块体材料(块石和卵石两种) 、护底等，结果表明对于山区河流，试图仅仅通过增加坝体单个块体重量或断面尺寸来提高坝体稳定性效果甚微；最后，根据西部地区的自然、经济、交通等条件，提出可以采用柔性混凝土铰链体等一类整体性较好的护面层作为散抛石坝的防冲毁措施，以期取得良好的工程效果。
