精密度

With good accuracy and precision, the method provides technical support for the management of phenolic wastes

该方法准确度高，精密度好，为此类废弃物的管理提供了技术依据

The proposed method is based on the cataly-tic action of Os on the oxidation of phthalin with hydrogen peroxide.

但是，常规动力学方法操作烦琐，条件不易准确控制，重现性和精密度较差，这些缺点限制了它的应用。

For the determination of polarizable anions, a pulsed amperometric detector has higher selectivity, precision and sensitivity.

在测定上述易极化阴离子时，脉冲安培检测器具有选择性强、精密度好和灵敏度高等优点。

When the sulfur concentration is in the range of 0～4 mg/L, the elemental sulfur has a linear relation with the peak current of polarography.

该方法灵敏度高，当元素硫浓度为0.1 mg/L 时仍可以看到明显峰电流；精密度和准确度较好，对1 mg/L 元素硫的测定，标准偏差为0.02；元素硫浓度在0～4 mg/L 浓度范围与极谱峰电流呈线性关系。

The result shows the excellent condition was in room temperature, 1-1.5 g of potassium iodide, 5mL of 1mol/L sulfuric acid and keep static station for 30 mm.

结果表明：选择在室温下加入1~1.59碘化钾、5 mL 1mol/L硫酸，静置30 min，结果准确，精密度高。
