The treatment of alkaline arsenic-containing wastewater is a significant environmental problem in nonferrous smelter which should be resolved emergently nowadays.

碱性含砷废水的达标排放是当今有色冶金工艺中急待解决的重大环境问题。

A large molecular sizing agent modified AKD was prepared through the reaction between alkyl ketene dimmer and polyamide then cationization by epichlorohydrin. The large molecular sizing agent has high positive charge and emulsifiability.

摘 要：将聚酰胺多胺与AKD反应，并用环氧氯丙烷将其阳离子化，制备出一种具有高阳电荷的改性AKD大分子，并在中、碱性条件下用该改性AKD对漂白硫酸盐阔叶木浆进行施胶。

The results showed that the strain HH407 was gram negative, rod shaped, aerobic, with a single polar flagellum, neither endospore nor capsule formed, about 0.4 ～0.7 μm×1.0～1.8 μm in size.

对从连云港海域筛选的一株产低温碱性蛋白酶的海洋适冷菌HH407进行的鉴定和生长特性研究结果表明，该菌为革兰氏阴性杆菌，好氧，端生鞭毛，无芽孢及荚膜，大小为0.4～0.7μm 1.0-1.8μm，在酪蛋白培养基的菌落特征为椭圆金黄色、光滑、半透明、四周隆起。

A strain HH407 which could production cold-active alkaline protease, was isolated from the sea area of Lianyungang. Then, the identification and physiological characterization of the strain HH407 were studied. The results showed that the strain HH407 was gram negative, rod shaped, aerobic, with a single polar flagellum, neither endospore nor capsule formed, about 0.4~0.7 μm×1.0~1.8 μm in size. The colony on screening medium were circular, yellow color, smooth, translucent, convex with regular edges.

One of the main reasons for Energizer entering the Chinese market was to capitalize on the worlds largest market.

它们成为了中国大陆碱性电池市场的领先者。

They may not be Energizer, but I think they're still powerful batteries.

它们或许不是劲量金顶碱性电池，但是我想它们应该还是很强力的电池。

Since the aldehyde groups can be reversibly converted into enol groups depending on acidity and alkalescence of environment, the inter-and intra-molecule interaction of CMDA can be adjusted by changing the pH of medium, as a result, the self-assembly behavior of CMDA may be altered.

结果表明，CMDA在水中自组装形成纳米自聚集体，在pH=4.0和pH=10.83溶液中CMDA的临界聚集量浓度值分别为0.002mg／mL和0.005mg／mL，比中性环境中的临界聚集量浓度（0.02mg／mL）低了1个数量级。3种pH条件下自聚集体溶液表面张力具有共同的变化趋势，但在酸性与碱性条件下具有更好的表面活性。

According to the equilibration principle of electronegativity,a new scale for acid-basecapacity of hydroxides is established in the peper.

应用电负性均衡原理，建立一种新的标度氢氧化物酸碱性强弱的定量方法。

In borate solution, The order of effective mobilities of disaccharide-borate compolexes was saccharose＜celloiose＜ maltose＜lactose and that of polylol- borate complexes was ethylene glycol＜ propanetriol＜erythritol＜sorbitol＜mannitol＜dulcitol.

在碱性四硼酸钠溶液中二糖硼酸络合物淌度顺序为：乳糖＞麦芽糖＞纤维二糖＞蔗糖，多元醇硼酸络合物的淌度顺序为：六羟基多元醇＞四羟基多元醇＞三羟基多元醇＞二羟基多元醇。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
