trace concentration
1.Based on the observed data that consist of the water flow velocity,water depth and the distribution of trace concentration from the trace experiment,the calculated values of transverse mixing coefficient and longitudinal dispersion coefficient are 0.32m~2/s and 40m~2/s respectively.
2.Research into test method of trace CIO~- concentration within micrometer scale of conductive film surface
3.The aim of this study was to define the changes of cellular trace element concentration during the carcinogenesis process of Wistar rat palatine mucosa squamous epithelial cell induced by 4 nitroquinoline 1 oxide (4NQO).
4.Geographic association,zonation,affinity of certainmetals with particular granite type,relation between trace element concentration in a giv-en intrusion and the associated deposits,and the age consistency between ore formationand granite intrusion are the evidences which support a genetic affiliation of mineral de-posits to the granitoid intrusions.
5.DETERMINATION OF TRACE NO_2~- IN HIGH CONCENTRATION OF Cl~- SAMPLES BY GRADIENT ION CHROMATOGRAPHY
6.A modified computer spectrum-stripping method in ICP-AES with PDA or CCD as detector is developed for determining trace elements in multicomponents system of high concentration matrix without knowing concentrations of the matrix components.
7.Direct Analysis of Trace Rare Earth Elements Through Nanometer-size Titanium Dioxide Separation/Concentration and Fluorination Assisted ETV-ICP-AES with Slurry Sampling
8.The trace selenium in wild almond was determined by AFS, the effect of the acidity and the concentration of the reducing agent were studied.
9.Separation and Concentration of Trace Au with Macroporous Weak-alkali Trimethylamine Resin and Its GFAAS Determination
10.Study on Large Bore Coated Column for Adsorption and Concentration of Trace Organic Compounds in Water
