He small diameter foam diamond wire line drilling tests have first been made using the equipments and circulation system made in China. The maximum hole depth is 217. 74 m. 采用国产设备及自行设计配套的灌排系统首次在国内进行了金刚石泡沫绳钻试验,达到了217.74m的最大应用孔深;
Based on the relative theory study of foam both here and abroad and large amount of tests in lab, we develop ZX-1, a new set of foam cleaning fluid system. 在调研国内外泡沫理论相关文献的基础上,跟踪和吸收了国内外关于泡沫理论的最新研究成果,根据试验系统地研制了ZX-1泡沫洗井液体系。
The mechanical properties and statistical curves of raw materials ( PU, PVC foam, plywood, pine wood and GFRP) for GFRP sandwich components of high speed ships are presented through a large number of tests, giving a reference to designs of high speed GFRP ships. 通过大量试验,给出高速船玻璃钢夹层结构件原材料(聚氨酯泡沫塑料PU、聚氯乙烯泡沫塑料PVC、多层胶合板、松木和玻璃钢等)的力学性能及统计曲线,可供高速玻璃钢船设计时使用。
The changes in mechanical and physical properties and chemical structure of polyvinyl formal ( PVFM) foam caused by hygrothermal ageing tests were studied by means of IR and other measuring methods. 用红外光谱和其他测试方法对聚乙烯醇缩甲醛(PVFM)泡沫材料湿热老化前后力学性能、物理性能和化学结构的变化进行了研究。
