GB/T 5698 color terms TESTING term GA/T 242 trace evidence3 Terms and DefinitionsGB/T 5698, GA/T 242 as well as established the following terms and definitions apply to this section. 3.1 Determination of material with tiny microscopic spectrophotometer at a specific light source for generating light radiation energy absorption, reflection and transmission, fluorescence The wavelength of the illumination source and the amount of between, and to determine the fine material itself absorbs, reflects in a specific wavelength range, transmission, fluorescence The spectral characteristics (ie, spectrum) in order for the composition or the physical structure of the tiny substances qualitative and quantitative analysis or comparison methods. 3.2 A method of combining a microscope spectrophotometer instrument, it can be observed that are so small, the measurement optical amplification region, And a variety of optical characteristics of this region, such as absorption, reflection, transmission, fluorescence spectrum characteristics were measured. 3.3 Substances on the energy of the incident light may be selected to absorb, absorb the magnitude of the relationship diagram between the wavelength of incident light is called the absorption spectrum. 3.4 Incident light objects, the magnitude of the incident by the diagram of the wavelength of incident light between objects is called a transmission spectrum. 3.5 After the incident light objects, diagrams magnitude of the wavelength of the incident light is reflected back to the object called the incident between the reflection spectrum. 3.6 In addition to the visual image features characteristic of the light effect on the human eye and cause, including. a) the observer can be used to distinguish between the same size, shape and structure of the field between the two visual phenomena or visible radiation characteristic; ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 19267.8-2008_English be delivered?Answer: Upon your order, we will start to translate GB/T 19267.8-2008_English as soon as possible, and keep you informed of the progress.
