Grains of different varieties need different stokes and rotating speeds so as to obtain a desired capacity and separating efficiency 對不同品種的谷物,需要有相應的沖程長度和轉速,才能獲得所需的產量和分離的質量。
The law of the overflow ratio on the separating efficiency and the pressure drop was discovered through a series of tests and the causes were analyzed 通過一系列試驗找到了溢流分率對分離效率和壓力降的影響規(guī)律,并且分析了產生這些影響規(guī)律的原因。
The aqueous two - phase system has been applied to the separation of biomolecules because of its gentle character , easy operation and high separating efficiency 摘要雙水相體系由于性質溫和、操作方便、分離效率高,以及不會導致被分離物質的破壞和失活等優(yōu)點,被廣泛應用于生物大分子物質的分離和純化。
Sectionii : to research and establish a kind of high efficient purification model of recombinant proteins produced in escherichia coli as inclusion bodies . to raise separate efficiency and biological active efficiency is especially important in the purification model of recombinant proteins . in accordance with these questions , we raise inclusion bodies purity before the purification as far as possible , and select the suitable chromatogram technology 研究并建立一種包涵體中高效分離純化目的蛋白的優(yōu)化模式重組蛋白分離純化工藝中分離效率的提高、生物活性效率的提高及工藝的穩(wěn)定性是尤其重要的,針對這些問題,我們在層析純化前盡山西醫(yī)科大學生物化學與分子生物學2003屆碩士學位論文可能地提高包涵體純度,并選擇合適層析方法的同時合理的組合色譜分離單元。
Aimed at solving the problem that high content of unburned carbon is unfavourable for the comprehensive ultilization in scale of fly ash , the fundamental principle that separation of unburned carbon from fly ash is theoretically analyzed by wet flotation and dry electro - separation , three factors and two levels orthogonal test for flotation and two factors and three levels test for electro - separation were conducted , furthermore , the primary factors and law affecting separating efficiency in flotation and electro - separation were obtained . the results show that wet flotation can give 7 . 34 % of the cleaned coal yield rate , which contains 44 . 53 % of ash content and 56 . 02 % of separating efficiency , while dry electro - separation can reduce the content of carbon in separated fly ash to 3 . 16 % and remove 53 . 12 % of carbon from fly ash 針未燃炭含量過高不利對粉煤灰大規(guī)模綜合利用的問題,從理論上分析了粉煤灰濕法浮選和干法電選分選未燃炭的基本原理,進行了三因素二水平正交浮選試驗和二因素三水平的正交電選試驗研究,得到了影響浮選和電選分選效果的主要因素及其規(guī)律.試驗表明:采用濕法浮選法可獲得精煤產率為7 . 34 % ,灰分為44 . 53 % ,分選效率為56 . 02 %的分選效果;采用干法電選,選后粉煤灰的含碳量可降到3 . 16 % ,脫碳率達53 . 12 %
