As the film sample is fixed on one plane by tighten bolt,this device can realize the deflection of optical path.And the reflectivity of the sample is measured by using oblique incident ray.

使用该装置并通过平面和样品背后的顶丝固定薄膜样品的安装方式，可实现光路转折，完成斜入射光对薄膜样品反射率的测量。

Pararosaniline was the most accurate and sensitive method of determining SO2 residue, and it was fit for the samples of any SO2 content. Improvement pararosaniline method was only fit for the samples of high SO2 residue. Iodometry was not fit for the deep color samples and low SO2 residue samples. The fast determination method could be used the quality and semi-quantitative determination of SO2 residue in edible fungus.

副玫瑰苯胺比色法是检测SO2残留最准确、最灵敏的方法，适合于各种SO2浓度的样品；改良的副玫瑰苯胺比色法只适合于高SO2残留的样品；碘量法不适宜检测深颜色的食用菌，而且在检测低SO2残留样品时准确度不高；快速测定法可用于食用菌产品中SO2残留的定性检测和半定量分析。

5 Formula: x 1: sample lixivium the content of zinc, mg/litre; m determination of samples taken lixivium zinc,μ g; V determination of samples taken, mL liquid immersion.

8.5 计算式中：X1——样品浸泡液中锌的含量，mg/L； m——测定时所取样品浸泡液中锌的质量，μg； V——测定时所取样品浸泡液体积，mL。

Large-volume injection in capillary gas chromatography was developed for determining the trace components in environmental samples and for reducing the need for cleanup step, also for on-line connection of liquid chromatography with CGC. The key features of the LVI include sample retained by a large capacity volume liner or a retention gap, and solvent vapor eliminated by solvent vapor exit.

在毛细管气相色谱法中，采用大体积进样技术，即使用能够容纳大体积样品的进样装置以及增加可控时间的溶剂蒸汽放空装置，可以满足环境样品中超痕量组分的分析要求，简化样品浓缩步骤以及实现液相色谱与CGC的在线联用。

Determine with atomic spectrophotometer the plumbic content in sample of lacteal precious capsule, decide look, standard to lay in fluid to make up from sample metage, sample according to mathematical model, equation of regression of standard curve linear and repeat the calculation that measures 5 respects to undertake uncertainty of measurement.

用原子分光光度计测定乳珍胶囊样品中的铅含量，根据数学模型从样品称量、样品定容、标准储备液配制、标准曲线线性回归方程和重复测量5个方面进行测量不确定度的计算。

It is found that the sample stained with silver methenamine instead of mercaptoacetic acid-osmium can prevent the false phenomena caused by the inappropriate use of mercaptoacetic acid.

摘 要：本文将六亚甲四胺银染色法作为加工毛发的电子染色剂得到较好的电子显微图像，并系统地比较了用巯基乙酸-锇法染色的羊毛样品和用六亚甲四胺银染色的人发样品的超微结构，认为对深加工过的毛发样品用六亚甲四胺银法替代巯基乙酸-锇法染角蛋白，可以防止巯基乙酸使用不当引起的假象。

First, the quantity of gene with a special sequence is rare, commonly in microgram or less, which conflicts with the need for large samples of DNA in the solution methods.

首先，特定序列的基因样品通常是很少量的，大约在毫克级甚至更少，而溶液化学方法往往需要消耗大量的DNA样品，如果采用表面化学方法则此矛盾就可得到解决，只需极少量的样品就可进行研究。

In this paper, the free surface and the sticking miler surface of the ribbons after corrosion in HF solution at different corrosive depths were observed by AFM.

将310℃和540℃退火的样品在HF酸溶液中进行腐蚀，获得不同腐蚀深度的腐蚀表面，再用AFM观测其表面形貌，则发现：在310℃退火样品的腐蚀表面，自由面和贴辊面形貌各自随腐蚀深度的变化而变化，并且两表面形貌之间在腐蚀前期有差异，但后期无明显不同；而540℃退火样品的两个腐蚀表面，则不存在这样的变化和差异。

The sample proportion has mean and variance and (3.7) In Section 14.1.4 we show that for , and have covariance (3.8) The sample proportions have a large-sample multivariate normal distribution.

样品比例有手段和变化并且(3.7)在部分14.1.4 我们显示那为，和有协变性(3.8)样品比例有大样品多维分布的正常分配。

The measurements of the transport properties indicate that the crystal exhibits a semiconductor behavior with p-type carriers and the thermal activation energy was estimated to be about 0.18 eV.

我们测量了制备样品的电阻率和热电势特性，样品表现出典型的p型半导体行为。经对电阻率和热电势数据的拟合，得到样品的热激活能△=0.16-0.18eV。

In the United States, chronic alcoholism and hepatitis C are the most common ones.
