"The term is also used for sodium nitrate and calcium nitrate, both of which are used in the nitric acid industry and as fertilizer s, and for ammonium nitrate, a high explosive and fertilizer "

这一名词也用于表示硝酸钠和硝酸钙，此两者在硝酸工业中被当作肥料使用。硝石也指硝酸铵，一种高爆炸性炸药和化学肥料。

Under the optimum conditions, the analytes could be separated within 17 min in a 75 cm length capillary at a separation voltage of 18 kV in a 10 mmol/L borate buffer (pH 8.2). A 300 μm diameter carbon disk electrode generated a good response at+ 0.95 V vs. saturated calomel electrode (SCE for all analytes. The relationship between peak currents and analyte concentrations was linear over about three orders of magnitude with detection limits (S/N=3) ranging from 78 μg/L to 110 μg/L for all analytes.

在优化的实验条件下，以直径300μm的碳圆盘电极为工作电极，检测电位为＋0.95V，在10mmol/L硼酸盐(pH8.2)的运行缓冲溶液中，上述6种活性成分能在17min内实现很好的基线分离，被测物浓度与峰电流在3个数量级范围呈良好的线性关系，检出限(S/N=3)范围为78~110μg/L。

In this paper, a novel algorithm for high resolution DOA estimation is proposed, which not only skips sources number estimation and EVD, but also behaves satisfactorily with a few snapshot, it may be viewed as a combination of merit of conventional Capon and MUSIC method.

该文提出一种超分辨的DOA估计算法，此算法不需要预判信源个数和进行特征值分解，同时在时变环境中，针对快拍数较少的情况下，依然保持较高的角度分辨能力，可以被认为是综合了Capon法和MUSIC法的优点。

After 3 days, 99% of carbazole and 15% of dimethyl carbazole was degraded. And the removal rate of 1-, 2-, 3-, and 4-methyl carbazole was determined to be 63.4%, 87.6%, 78.4%, and 66.5% respectively.

在柴油脱氮过程中，发现3 天后， 99%的咔唑被降解，四种单甲基咔唑的降解率为63.4%~87.6%，二甲基咔唑共降解了15%。

Envirofit's latest stoves, introduced this year in a project sponsored by the Shell Foundation, use a carburettor design, with chimneys that draw air in through precisely calibrated inlets.

Envirofit的最新炉具，今年在壳牌基金会赞助的一个项目中被引进，使用一种化油器设计方案，通过精确校准的进气口放进空气。

It is also used as a carminative and forms an ingredient of a number of ayurvedic recipes.

它也被用作阿育吠陀食谱中的一种成分。

"This could be the first time in more than a century that a new carnivore has been discovered on the island," said the WWF in a statement.

该基金会在一份声明中表示，"这可能是一个多世纪以来，一种新的食肉类动物首次在该岛被发现"。

This paper also analyzes control problem in cartesian space and presents several improved indirect methods , to counter kinematic uncertainty ect.. Then, a sliding mode control and an adaptive control are proposed as direct cartesian space control scheme. All of them has been extended to redundant manipulator.

本文研究了机械手工作空间控制问题，提出了考虑具有不确定运动学参数等多种改进的分解运动控制方案，它是机械手控制的间接方法，进一步本文又提出了滑动模及自适应两种分别考虑运动学及动力学不确定性的工作坐标直接控制方案，它们均被推广至具有冗余自由度的机器人控制中。

Bacteria often sequentially utilize coexisting carbohydrates in environment and firstly select the one easiest to metabolization. This phenomenon is known as Carbon catabolite repression.

细菌在多种碳源共存的环境中优先利用一种的现象被称为分解代谢产物阻遏效应。
