Methods: Copper was determined by catalytic kinetic spectrophotometric method which was based on the copper catalyzing oxidation of brilliant green by potassium chlorate and hydrogen peroxide in potassium hydrogen phthalate-sodium hydrate buffer solution at pH4.20. The absorbance was measured at 624 nm.

在pH4.2的邻苯二甲酸氢钾－氢氧化钠缓冲溶液介质中，利用铜离子催化氯酸钾和过氧化氢氧化灿烂绿的指示反应，通过测量624 nm下吸光度的改变，用催化动力学光度法测定痕量铜。

Metallic-compound oxidizers, such as potassium nitrate or potassium perchlorate, generate condensed-phase products of particularly high molecular weight, which is rather undesirable.

金属复合氧化剂，如硝酸钾或高氯酸钾，产生凝聚相的产品，尤其是高相对分子质量，这是相当不可取的。

Anodic oxidations may be carried out with alkaline solutions of nitrate s, perchlorates, fluoroborates, or fluorosilicates.

在硝酸盐、高氯酸盐、氟代硼酸盐或氟代硅酸盐的碱性溶液中通过阳极氧化作用可制备PbO2。

The nitrate and chlorate, very volatile, give off brilliant crimson flames and are used in flares, fireworks, and tracer bullet s.

卤化锶、硝酸锶和氯酸锶极易挥发，并能使火焰呈亮猩红色，用于各种照明弹、烟花和曳光弹中。

Cellulose fibre and blended polyester fabrics are normally bleached using hydrogen peroxide or sodium hypochlorite .

纤维素纤维和混合的涤纶一般用过氧化氢或次氯酸钠来漂白。有时也用亚氯酸钠来漂白。

While the sample was dissolved in nitric acid and hydrofluoric acid, the silicon in sample was removed through evaporating in the form of silicon fluoride. As a result, the matrix interference was eliminated, and meanwhile the high blank value as well as the influence on the life span of graphite tubes due to perchloric acid was avoided.

使用硝酸和氢氟酸消解样品，使硅生成氟化硅蒸发掉，消除了基体的干扰，也避免了使用高氯酸作为消解试剂所引起空白值高及对石墨管寿命的影响。

This method could be used in determination of sodium glutamate in chicken essence.

对鸡精样品进行预处理后，采用高氯酸滴定法测定鸡精中谷氨酸钠的含量，方法重现性RSD为1.53，回收率为98.0%，可应用于鸡精产品中谷氨酸钠含量的检测。

Sodium glutamate content in chicken essence was determined by perchloric acid titration after pretreatment with the sample.

对鸡精样品进行预处理后，采用高氯酸滴定法测定鸡精中谷氨酸钠的含量，方法重现性RSD为1.53，回收率为98.0%，可应用于鸡精产品中谷氨酸钠含量的检测。

Subsequently, chlorate-resistant experiment and growth experiment were used to verify the stability of their NR deficiency.

然后用氯酸盐抗性实验和不同氮源生长实验验证其NR突变的稳定性。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
