Miniaturization has already reduced reagent use relative to conventional sanger reactions one billionfold from microliters to femtoliters 與傳統(tǒng)的桑格定序反應(yīng),藥劑用量以微升做單位,現(xiàn)在的小型化儀器只需飛升,減少了10億倍。
The test results show that the combined collectors can not only improve t he separation results of cu , au and ag , but also reduce reagent and lime dosages without any change in process flowsheet and increase in facilities 結(jié)果表明,在不改變工藝流程,不增加設(shè)施的情況下,不但提高了銅、金、銀的選別指標(biāo),而且還可以減少藥劑用量和石灰用量,降低生產(chǎn)成本。
The borohydride reducing reagent supported by the strong acid cation exchange resin was prepared by the strong acid cation exchange resin reacting with sodium borohydride . the reductive ability of the resin reducing the carbonyl compounds is strong , so the yields are generally pretty high ( 51 % ? 用強(qiáng)酸型離子交換樹(shù)脂與硼氫化鈉作用制備了強(qiáng)酸型離子交換樹(shù)脂支載的硼氫化還原劑.探討了在不同溶劑中制備的還原樹(shù)脂的還原能力;應(yīng)用于還原羰基化合物時(shí)有良好的產(chǎn)率( 51 % ?
