| 1. | It has merits like fine heat stabilization good eroding resistion and so on 热稳定性好,抗冲刷,耐侵蚀能力强。 |
| 2. | Protection of plastics . part 1 . testing method for resistance of ingredients to microorganisms 塑料防护.第1部分:塑料成分耐微生物侵蚀能力的试验方法 |
| 3. | Protection of plastics . part 3 . testing method for resistance of equipment and apparatus to microorganisms 塑料防护.第3部分:器材和设备耐微生物侵蚀能力的试验方法 |
| 4. | Tests for the resistance to micro - organisms of natural or artificial cellulose textiles . method by mixed inoculation spores mycellium 天然或合成纤维素织物抗微生物侵蚀能力的试验 |
| 5. | Backing layer castable is noted for low heat conductivity , good quality of being a whole part and good erosion resistance to mental steel 久衬浇注料整体性好、不开裂、导热率较低,且具有一定的抗钢水和铁水侵蚀能力。 |
| 6. | With the addition of the mineral additives , the structure of the cement paste can be improved and the resistance of sulfate attacks can be advanced 掺入掺和料可以改善水泥浆体的结构,明显提高混凝土的抗硫酸盐侵蚀能力。 |
| 7. | With continuing of rainfall , the influence of soil - aggregated degree was very great . seventhly , mutual effect between soil crust and raindrop splash was studied , the result showed that splash erosion rate was greatly increased , once soil surface crust was formed 七、表土结皮形成对土壤溅蚀的影响:随着表土结皮的逐渐形成,土壤抗侵蚀能力增强,土壤溅蚀速率急剧减小。 |
| 8. | Its land producesfrom three quarters to a bale and a half an acre , and with careful tillage and in agood cotton year as much as a bale and three quarters to two bales to the acre . the increase in the value of the lands in the delta , both timber and cultivated , isremarkable 它与密西西比河平行南流,已无侵蚀能力,通过长距离后,才注入密西西比河。它的上游在丘陵区内,落差较大,已修筑许多水,作灌溉及发展水电之用。 |
| 9. | Water cement ratio and mixing fly ash or slag into concrete effect on ability of resisting chloride penetrating that are considered in the model . the effect of environment that include temperature , relative humidity and cumulating of surface chloride concentration of concrete are also considered . moreover , chloride diffusion changing with time is included in this model as well as 模型中考虑水灰比和混凝土配合比(掺入不同量的粉煤灰和矿渣)变化对混凝土抵抗氯离子侵蚀能力的影响,同时考虑温度、相对湿度和表面氯离子浓度累积变化等环境因素对氯离子侵入混凝土过程的影响,以及氯离子扩散系数随时间的变化。 |
| 10. | Results from weather monitoring stations from the area showed that precipitation in the two months accounted for 37 . 70 % total annual rainfall during the year under review and a significant positive correlation between the rainfall erosivity and rainfall intensity was found , which indicated that the erosive ability of rainfall could be better expressed by its intensity than the total amount of rain 2001年研究区降雨量和降雨侵蚀力均为6 、 8月较大,其中6 、 8月降雨量为全年的37 . 70 ;降雨侵蚀力与可产生侵蚀雨量为极显著正相关,可侵蚀降雨量比降雨量能更好地表示降雨的侵蚀能力。 |
