定性实验 meaning in Chinese
qualitative experiment
Examples
- This accomplishment can promote the confirmation of welding technique from experimental qualitative seeking to data quantitative analysis and represent a new method of welding technique . it greatly improve the quality of welding , improve the validity of welding technical cards
这一成果的实现，使焊接工艺的制定从定性实验摸索阶段提高到了定量计算且有理论依据的新阶段，并给焊接工艺参数的制定提出了一种新的方法，可大大提高焊接质量，提高焊接工艺卡的正确性。 - Thirdly , the contents should be organized . arrang the inorganic chemistry experiments , organic chemistry experiments and analytic chemistry experiments in a whole , and in order to make the experimental teaching more systematically , they should be separately organized as these parts : basic knowledge of chemistry experiment , basic operation experiment , experiment of chemical quality , qualitative experiment , quantitative experiment synthesis , extration and experiment design
三是内容的组织，将无机化学实验、有机化学实验和分析化学实验整体编排，按化学实验基本知识、基本操作实验、化学性质实验、定性实验、定量实验、制备和提取及设计实验等分块组织，以利于更系统地进行实验教学。 - The travel time of lcr wave and applied stress showed well linear relationship in the qualitative and quantitative experiments , experimental result matched with the theory , achieved the anticipative requirements . these experiments validated the feasibility of evaluating the stress with lcr wave based on tdc travel time measurement preliminarily
定性实验与定量实验显示, lcr波传播声时与加载应力具有良好的线性关系,实验结果与理论基本相符,达到了预定要求,也初步验证了基于tdc声时测量的lcr波应力检测方法的可行性。 - No trace of any newly expressed protein band was noticed in supernant as well as in the cells by sds - page , except the verification of the substitution of beta - galactosidase gene ( the lose of galactosidase protein band ) , which is a selective marker of the wild - type virus . elisa test results suggested the expression of egf in cells , but not in culture supernant . the quantitative calculation suggested the expressed egf was about 6 - 7 u g ( as egf standard ) per flask ( 2 > < 106 cells ) in the cellular extract
将重组病毒rbmbacph - egf以10moi感染bmn细胞， 72小时后收集培养细胞和上清；培养上清和经超声波处理的细胞样品elisa检测发现胞内样品中存在能与egf抗体免疫反应的产物，粗略估计表达量约6 7 g 2 10 ~ 6个细胞(相当于egf标准品) ；重组病毒rbmbacph - egf穿刺接种5龄家蚕幼虫，每隔24h收集蚕血淋巴，经elisa检测发现第4天表达量最高，根据egf标准曲线计算蚕血淋巴的表达量约32 g ml ； elisa定性实验还发现正常蚕血也存在与egf抗体间交叉反应的物质。
