| 1. | The stable tio2 sol was prepared by using ti ( oc4h9 ) 4 as precursor and c5h8o2 as chelate additive 以钛酸丁酯作前驱物,乙酰丙酮作螯合剂制备稳定的tio2溶胶。 |
| 2. | If the sintering temperature was lower than the reaction temperature , phase separation will develop 煅烧温度低于反应物的固相反应温度时,只能导致前驱物分相。 |
| 3. | The alternative possibility ? that living cells or their precursors arrived from space ? strikes many people as science fiction 还有一种可能性,则令许多人觉得宛如科幻小说情节:活细胞或其前驱物是来自外层空间。 |
| 4. | Tem , afm , xrd , tg - dta and laser particle size analyzer were used to characterize and compare the precursor and nano - scaling products 利用tem 、 afm 、 xrd和tg dta等几种测试方法对前驱物和纳米产物进行了表征。 |
| 5. | Then a chemical precursor to pdms ? a free - flowing liquid ? is poured over the bas - relief master and cured into the rubbery solid 然后把pdms的化学前驱物(一种可随意流动的液体)倒在浅浮雕主片上,使它凝结为固体橡胶。 |
| 6. | Although the droplets themselves are far from being alive , similar structures could have been precursors of the first primitive life - forms 尽管小颗粒算不上生命,可是第一个原始生命的前驱物,大概结构与它们很相似。 |
| 7. | For this reason , the most commonly discussed panspermia scenario involves the transport of microbes or their precursors from mars to earth 基于这个理由,最常受人讨论的胚种说就是:微生物或其前驱物,是从火星送到地球的。 |
| 8. | All hi all , the coat layer distribute unevenly . with the increase of al2 ( so4 ) 3 . 18h20 amount , the flaky coat layer grow up and thicken 并且随覆层前驱物加入量的增加,沉淀法改性石墨表面局部富集的絮状覆层物质增多,覆层变厚。 |
| 9. | Alumina sols of different content were prepared by using al ( o - sec - bu ) 3 as precusor , water as solvent and nitric acid as peptizer 以异丁醇铝为前驱物、水为溶剂、硝酸为胶溶剂制备了不同浓度的氧化铝溶胶,进而采用提拉法和旋覆法制备了致密氧化铝膜。 |
| 10. | And ha molecules were synthesized in vitro utilizing excessive active udp - glca and udp - glcnac sugar nucleotide precursors in the presence of a divalent mg2 + or mn2 + ion 经转化大肠杆菌dh5a和iptg诱导表达,提取原生质膜在体外利用活性前驱物合成了透明质酸。以s |
