Standard guide for addressing variability in exposure testing on nonmetallic materials 非金属材料曝光测试中变异度表达的标准导则
Relationship between heart rate variability and diabetic nephropathy in type 2 diabetic patients 2型糖尿病患者心率变异度与糖尿病肾病的关系
Characteristics of heart rate variability can predict impending septic shock in emergency department patients with sepsis 以心率变异度预测急诊室败血症患者是否产生败血性休克
The value of discrimination power and the exclusion chance of paternity for these y - str loci are same as the value of haplotype diversity 单倍型变异度为0 . 9991 ,其个人识别能力和非父排除率也为0 . 9991 。
Result a multiplex pcr system of four y - str loci ( y - a489 - plex ) was established . here , y - a489 means the selected loci dys434 , dys438 , dys439 , a10 在100个样本中检出37个单倍型,单倍型变异度为0 . 9628 ,标准误为0 . 00429 。
They were suitable for improving identification power of polymorphic markers on chromosome y . our approach of hplc can separate the oligonucleotides with different size and same size with different sequences , and provide a method to quantity products of snupe 单倍型变异度表明这8个丫str具有较好的个人识别能力和非父排除率,能够较好地提高y染色体遗传标记的个人识别和非父排除能力。
5 ) the variety , a famous concept proposed by the precursor of cybernetics , ashby , is extended from variable to systems . with the definition of system variety , the gotten conclusions lead to two new laws of variety in control systems : " the general conservation law of variety " for regulation systems , and " the law of requisite variety " based on the proposed basic information condition for tracking systems 5 )将ashby提出的变异度的概念由信号推广到系统,给出了系统的变异度定义,进一步阐述了控制系统的变异度定律:针对调节系统,提出了“广义变异度守恒定律” ,对前人的结论进行了修正;针对跟踪系统,提出了基于基本信息条件的“变异度必备定律” 。
