氢氧化物

In the future, rover-based explorations of the hydrate deposits and clay beds could reveal solid evidence for a red planet that once thrived with microbiotic life.

在未来，以自行装置为基础，对氢氧化物沉淀和粘土层的探测，可能会提供可靠的证据：在这颗红色的行星上，微生物曾经旺盛地生长着。

Compared of the efficiency of treating heavy metals in FGD wastewater with NaOH, Ca_2 and Mg_2. It indicated that NaOH was much efficient for precipitated waste water; Ca_2 was much efficient for unprecipitated waste water, the removal efficiency reached 98.4%. With the increasing of the main ion of Ca~2+, Cl~- in FGD wastewater, the efficiency decreased. It decreased 60% for the removing of Mn and 10% for Zn, Cd and Ni. The rectification coefficient token the Ksp of practical wastewater because it quite different with theoretic Ksp at different pH; the theoretic and practice addition were proportioned and it commonly reached 1:300.The precipitation efficiency of Na2S at different pH and the effect of Ca2+ was determined.

比较了NaOH、Ca_2和Mg_2处理脱硫废水时重金属的去除效果，分析了Ca~(2+)、SO_4~(2-)和Cl~-等主要离子的影响，结果表明：NaOH和Ca_2能有效处理脱硫废水中的重金属；对澄清废水而言，NaOH效果较好，对于未澄清废水而言，Ca_2效果更好，但去除废水中重金属的效率都能达到98.4%；随着Ca~(2+)、Cl~-等主要离子浓度的增大，中和作用去除重金属的效率降低，Mn最大降低60%，Zn，Cd，Ni降低10%左右；实际重金属浓度和用理论Ksp计算所得值差别很大，通过校正系数能有效计算实际重金属浓度；实现相同pH时氢氧化物的理论和实际投加量成一定比例，最大可达1：500。

Minerals formed in the presence of water, called hydrates, can be detected using infrared spectroscopy.

在水中形成的物质被称作氢氧化物，利用红外线光谱仪就能发现它们。

Moreover, copper ions were isolated as hydroxides, which is beneficial to the separation of copper from nitrated products.

而且，硝化过程中铜以氢氧化物固体沉淀的形式析出，便于与硝基化产物分离。

In this paper,based on the principle of LDH synthesizing in-situ,with spectrophotometry and XRD analyses of solid,removal efficiency and mechanism of acid orange from dye aqueous solution were studied.

In the method, the organic base is used instead of the hydroxide of an alkaline metal such as NaOH and KOH.

在方法中，用有机碱而不是碱金属的氢氧化物如NaOH和KOH。

Take a Blue Sensitive Cyanine Dye and Ampicillinum Natricum an example. These two material both have good result and it it proved to be an effective tool for direct oscillographic analysis of organic.

以氨苄青霉素和感蓝染料3，3′-二(3-磺丙基)-4，5-苯并噻菁氢氧化物的三乙氨盐为例，二者在银盘电极上均有较好的示波响应，为示波分析直接进行有机分析提供了有效工具。

Hydroxides include the familiar alkalies of laboratory and industrial processes.

氢氧化物包括实验室和工业过程中常用的碱。

Iron and aluminum hydroxides are present in soils in both crystalline and amorphous forms.

土壤中出现有结晶和非结晶形式的铁和铝的氢氧化物。

The solubility of the hydroxides increases as the elements get heavier.

随着元素的质量增加，氢氧化物的溶解度逐渐减小。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
