According to the experiment, of the three stages such as desorption, diffusion and seepage in gas flow, the main factor which effected the gas producing speed in the coal seams is got. 分析得出煤层甲烷排放解吸、扩散和渗流三个阶段中,影响煤层产气率的主要因素。
In the process of adsorption and desorption, diffusion is the dominant factor. 扩散在吸附、脱附过程中为控制因素。
Under the same laser intensity, the peptide polymer with different structure produced a different percentage of desorption ionization, which suggests that the optimization of laser intensity is a key factor for analyzing peptide structure. 相同的激光强度对不同结构的多肽多聚体产生不同的解吸离子化百分率,优化激光强度是准确分析多肽结构信息关键因素之一。
Desorption test investigate the influence of the test condition to activated carbon adsorption test, Seeing about the influence factor of the microwave power 、 the calefaction time of microwave 、 the flow velocity of carry gas. 解吸试验研究了实验条件对活性炭解吸试验的影响,考察了微波功率、微波加热时间、载气流速等对活性炭的影响,并提出最优试验操作条件。
The order of Df ( desorption factor) value was: yellowish red soil> silt-loamy soil> kaoline> perlite> paddy soil ( loamy clay)> kieselguhr. 解吸因数的大小排列顺序为:黄红壤、粉泥土、高岭土、珍珠岩、青紫泥、硅藻土。
This paper studied dynamic desorption technology of Mulberry red pigment in LSA-21 macroporous resin by single factor tests and orthogonal experiments, and found out the best operational conditions by variance analyses. 运用单因素实验和正交实验研究了桑椹红色素在LSA-21大孔吸附树脂上的动态洗脱工艺,经极差分析和方差分析确定了其最佳洗脱条件。
On the other hand, it is concluded from the desorption experiment that the CEC content in soil is the most significant factor that affects the chlorpyrifos desorption of soil and that the potassium content also plays an important role. 毒死蜱解吸实验时,土壤中CEC含量是影响土壤对毒死蜱解吸作用的最重要因素,土壤中速效钾含量也对毒死蜱的解吸有着重要的影响。
