| 3. | The multiple colloid has micro pore can keep warm to reach fuel normal temperature and flash point 多孔性的组织气孔有保温作用,可蓄温使油的温度达到一定的温度,提高燃点。 |
| 4. | Another type of composites , sulfur / active carbon composites , possess the structure of sulfur incorporated in nano and micro pores of active carbon 另一种减小单质硫颗粒的办法是将单质硫嵌入具有纳米级孔和微孔的活性炭中。 |
| 5. | Based on the analysis and research on test results , it discusses the existence of low water - cut oil layers due to porous media and pore water in micro pores of reservoir 在分析研究化验资料的基础上,探讨了储层存在多孔介质、微细孔隙水等产生低含水油层的原因。 |
| 6. | Percolation irrigation takes way of underground micro - irrigation which worked with the aid of micro pore pipes for percolation that is buried at root zone . and the crops " demand for water can be met by percolating through the soil on the condition of low pressure at the right time with right volume 渗灌是一种地下微灌形式,在低压条件下,通过埋于作物根系活动层的灌水器(微孔渗灌管) ,根据作物的生长需水要求适时适量地向土壤中渗水供给作物。 |
| 7. | 4 ) the major reservoirs are dominated by types of medium matrix - pores and developed fractures , with features of " large pores and small fissures " and " large fractures and micro pores " . statistic analysis shows that when matrix porosity is less than 5 % or fractural density lower than 1 piece per meter , the volcanic rocks are difficult to become or shape reservoirs 该区主要储层为基质孔隙中等裂缝发育型, “大孔小缝”或“大缝小孔”均可形成储层,经统计分析,当基质孔隙度低于5及裂缝密度小于1条/ m的地层,不易形成储集层。 |
| 8. | Abstract : based on the test results of frost micro pore structure density distribution of high strength concrete at minus temperat ure ( hscmt ) , the frost damage fiber bundle model of hscmt was buitl . the purpose is to study frost damage factor of hscmt in the future , to deduce lost efficiency p robability of hscmt and prevent hscmt from frost in cold weather 文摘:根据负温高强混凝土冻结显微孔结构密度分布结果,建立了冻结损伤纤维束模型,为进一步研究负温高强混凝土的冻结损伤基因,推断负温高强混凝土的失效概率,及负温高强混凝土受冻害的防止打下基础。 |
| 9. | 4 , by making use of micro pore and permeability apparatus and optopn multifunction microscope etc . advanced reservoir testing equipments , the ability to show heterogeneity from micro to macro has been improved largely . k - level / k is more than 1 . 4 in south region reservoir , that is to say , the permeability in section is worse comparing to that of level direction , which is caused mainly by mud layers : different stone facies results in different micro feature , and in the south region , fluvial sandstone has cementation , compaction , corrosion and exchanging diagenesis , which occurred in b stage of early period 4 、应用微孔渗仪和opton多功能显微镜等先进的储层测试仪器设备,大大提高了从宏观到微观表征储层非均质的能力;南区储层中k _ (水平) k _的比值一般大于1 . 4 ,即垂向上渗透率相对于水平渗透率差,这主要是砂岩中泥质纹层造成的;不同岩石相的微观特征不同,南区河道砂储层主要有胶结、压实、溶蚀和交代等成岩作用,成岩阶段属早成岩b期。 |
