| 1. | Zno is a kind of white powder , which consists of infinitive form particle or needle - like particle , it is insoluble in water , soluble in acid and alkali solution 本品为白色粉末,由无定形颗粒或针状颗粒组成。不溶于水,溶于酸和强碱溶液。 |
| 2. | In addition to fabricate coatings on the surface of titanium alloys , the bioactivities on the surface of titanium alloy substrates were done by alkali solution 除了在钛合金表面制备涂层外,还尝试了对钛合金基体表面直接采用碱液处理的方法进行表面生物活化。 |
| 3. | Third , we designed a waste gas disposing equipment , through which the danger gases such as sih4 can be get rid of by the nitrogen diluting and the rinsing of alkali solution 设计并制作了尾气处理装置,使设备排出的尾气能够经氮气稀释和碱水清洗而除掉其中的sih _ 4等易燃有害气体。 |
| 4. | After de - acetylating chitin , chitosan can be easily dissolved in a dilute acetic acid solution , and chitosan fibers can be made by extruding the solution into a dilute alkali solution 甲壳素脱乙酰基后得到的甲壳胺可以很方便地溶解在稀醋酸水溶液中,经喷丝孔挤出后用稀碱中和沉淀即可得到甲壳胺纤维。 |
| 5. | The result was preferable while use tap water , acidic solution with ph = 3 . 0 and alkali solution with ph = 12 . 0 as regenerant . for the convenience of operation , it is suggested to adopt tap water as regenerant 用自来水、 ph = 3 . o的酸液和ph = 12 . o的碱液作为再生剂分别对吸附后的黑化砂进行再生,发现再生效果都比较好。 |
| 6. | The sbf cultivation results by different surface modification methods were : nano - tio2 coating > alkali solution treatment > tio2 coatings sintered in normal pressure > tio2 coatings sintered in vacuum 不同表面改性方法的sbf培养结果比较为:纳米二氧化钛涂层碱液处理方法常压下烧结二氧化钛涂层真空下烧结制备的涂层。 |
| 7. | Its effects of anti - stain treatment after dilute alkali solution immerse can be markedly increased , wood natural color lasts longer than the original ones , the color value still can reach a standard in export after aging for six months in air 稀碱液处理后再进行防变色处理,防变色效果显著提高,木材的天然色泽保持时间持久,大气老化半年后,色泽指标仍能达到外贸出口a级板标准。 |
| 8. | The electrode character of tourmaline particles influences the redox potential of water and regulates the ph value of solution to the weak alkali . the element sites on the surface of tourmaline powder play a bigger effect on acid solution than alkali solution 由于电气石表面的电场作用,电气石的电极性能够影响水体的氧化还原电位,可维持水体为弱碱性,并分析了电气石粉体表面位的影响。 |
| 9. | The physical methods include mechanical scarification , low and high temperature , hydration - dehydration , irradiation , high pressure and other physical treatments , and the chemical ones include acid scarification , alkali solution soaking and other organic chemical treatments 物理方法有机械损伤、低温和高温处理、干湿交错处理、辐射和高压处理等;化学方法有酸蚀、碱液浸泡和有机溶剂等处理。 |
