The natural dye sorghum red was extracted from sorghum and tested for dyeing cotton by orthogonal and single - factor expts . with direct , pre - mordant and post - mordant dyeing methods 摘要先对高粱红天然染料进行提取，然后通过正交试验及单因素试验对棉织物进行了直接染色、预媒法染色、后媒法媒染染色试验。
Quantitatively analyses the concrete influences on atomizing humidifying performance of the nozzle aperture , initial temperature and the pressure of spray water and the water - air ratio through a single factor experiment 通过单因素试验定量分析了喷嘴孔径、喷水初温、喷水压力以及水气比对雾化加湿的具体影响。
And the author founds investigation item filtration can improve precision and veracity of model and provides the single - item test method to reach the goal mentioned above 在模型验证中发现，要提高模型的精度和命中率，需要对调查数据项目进行有目的的筛选。本文提出的小样本单因素筛选方法可以提高模型的命中率。
The variable regularities of water - absorbing deformation and shear strength with initial water content , initial dry density and upper pressure are summarized as well as the quantitative correlations of them are described 总结出含水量、干密度、压力等单因素对加水变形和强度的影响规律，并对这种影响进行了量化描述。
Because sensitivity analysis only consider single factor and there are close relation between macro economic variables , its results is limited to the risk management of banks 敏感性分析只考虑单因素的影响,但实际上宏观经济要素的变化往往相互关联,相互作用,单一因素分析的结果对监管和银行风险管理的实践意义有一定局限性。
Secondly , the thesis employs 1003 listed companies in 2001 , empirically studies the relationship between industries with capital structure of china , and finds that different industries have different capital structure 对2001年末我国的1033家上市公司按照行业分类进行单因素方差检验，得出，不同行业有不同的资本结构。
3 . the experimental study about the test anxiety : the method of one - factor randomized design is adopted in this research . we engaged with cognition - behavior integrative training in the experimental group 三、小学高年级学生考试焦虑的实验研究本次实验采用单因素完全随机实验设计，在实验组进行考试焦虑的认知?行为综合训练。
By treatment with both ultraviolet rays and licl , a mutant strain b . s . lx - 19 with high yield of heparinase and stability was obtained , whose enzyme activity increased by 40 % over strain lx - 10 Lx ? 19 ，其肝素酶产量较出发菌株提高了40 。通过单因素条件研究，发现n源和c源对酶产量影响较大，接种量以10 ，初始ph6 . 5 ，种龄12h为宜。
Given the aim of the research is to found a method to evaluate the structures preliminarily , only the factors such as the bearing capacity , connections and compages , distortions , cracks are considered 基于本项研究的目的是要建立对于电力结构可靠性的初步评价，因此，本文的单因素评价主要考虑了承载力、连接和构造、变形、裂缝等因素。
The parameters of synthesizing technology of traditional aminosulfonic - based superplasticizers were optimized through mono - factor method . according to those optimum parameters , the performances of product were improved 以单因素法为基础优化了传统氨基磺酸盐高效减水剂的合成工艺参数，按照最佳合成工艺参数合成出的产品，其性能得到了改善。
