查询词典 acidified

Compared with the control, the percentages of living microorganisms on the biomembrane were 27.6, 14.1 and 0.01, respectively, after extracted by hydroxylamine hydrochloride （0.01mol·L^-1 NH2OH·HCl ＋ 0.01mol·L^-1 HNO3 ）, sodium dithionite （ 0.4mol·L^-1 Na2S2O4, pH 6.0 ）, and acidified ammonium oxalate.

经0.01mol·L^-1 NH2OH·HCl＋0.01mol·L^-1 HNO3、0.4mol·L^-1 Na2S2O4（pH6.0）和0.2mol·L^-1草酸氨（pH4.0）萃取后存活的微生物总量分别下降到原膜的27.6％、14.1％和0.01％；经15％HNO3萃取后，膜上只有极少数的细菌存活；而经H2O2／HNO3萃取后则无细菌存活、原生动物和藻类存活，说明选择性化学萃取剂的使用影响生物膜的活性。

Adding acidified barium chloride solution (BaCl2 + HCl), SO42 reacts to form a white solid.

加入酸化氯化钡溶液(BaCl2 + HCl)， SO42 反应生成白色沉淀。

The residue is then cooled and acidified with dilute hydrochloric acid. The toluene layer is separated off, washed with water and distilled. Toluene and other low-boiling fractions first distil over and finally pure diethyl phenylmalonate is obtained boiling at 165-166°C, under 20 mm. pressure and having m.p. 16 °C. The yield is 85% of the theoretical.

剩余物冷却然后用稀盐酸酸化，分理出甲苯层，用水洗涤，然后蒸馏，甲苯和其他低沸点馏分先被蒸馏出来，最后获得20毫米压力下沸点为165-166摄氏度的二乙基苯基丙二酸酯，其熔点为16摄氏度，理论收率为85%。

The best circumstance of the treating techniques of the acidified raw material is, temperture:37℃, starting pH: 7.0, material concentration:40g/L,digested sludge concentration ^.5 g/L and corn plasm was taken as organic nitrogen while ammonium chloride as abio-nitrogen.

同时对厌氧发酵生物产氢过程进行了试验研究，优化了产氢条件，其最适厌氧发酵产氢的工艺条件为，温度37℃，初始pH 值7.0，底物浓度40g/L，污泥浓度27.5g/L，以玉米浆为有机氮源，NH4Cl 为无机氮源。

与藿烷异常分布一起，表明海洋初级生产力的崩解，并进一步支持了西伯利亚火山活动引起大气、海洋及陆地生态系统危机的认识。5、首次提出了吴家坪／长兴界线附近的局部生物绝灭是由兰细菌勃发导致海水缺氧及毒化而引起的。

These facts showed that there exists a typical nitrosation reaction, because the reduction peaks in the I-V curves of green product and its acidified solution could be ascribed to typical nitroso aromatic compound.

因此，这一显色反应可认为是一典型的亚硝基化反应。

At first, the broth was acidified, then centrifuged to get mycelia, which was heated and powdered; finally we use acetic ether to soak the powder. After that, the phase of acetic ether was washed using the solution of ammonium sulfate and the solution of ethanedioic acid, then concentrated to gain pulps. It was crystallized at 4℃.The coarse crystals was decolorized by activated carbons, the pure needle crystal of lovastatin was obtained.
