In chapter 2 , we introduce some basic contents of groups and block designs 在第2章中,我们介绍了群论和区组设计的若干基本知识。
The balance comparison among simple randomization , stratified blocked randomization and minimization 中心分层区组随机化和最小化法的均衡性比较
Each unit covers a minimum area of 600 ha with a minimum yield target of 9 t / ha 每个生产区组最小面积不低于600公顷,最低的产量目标为每公顷9吨。
Methods adopting blockrandomized , open , positive western medicine and placebo parallel group controlled method , a total of 120 enrolled pati . . 方法采用区组随机开放阳性西药及安慰剂平行对照的方法。
In chapter 1 , we introduce some definitions , research background and the present situations about some kinds of large sets and overlarge sets of block designs , and give some examples 全文共分六章:第一章综述几种区组设计大集和超大集的定义、研究背景和当前的研究现状,并给出了一些具体例子。
The yield and the main botany properties of four culture types of medicinal chrysanthemum morifolium were compared and analyzed by adopting the randomized block design in the field experiment 摘要采用随机区组田间试验设计,结合方差统计分析方法,对药用白菊花4个栽培类型的产量和主要植物学性状进行比较分析。
The basic point of the two designs is to reduce the size of incomplete block , by using principle of confounding , to make fewer homogeneous experimental units fit to the size of incomplete block 这两种设计的基本特点是采用混杂的原理缩小不完全区组的大小,使较少的基因型同质试验单元可安排一个不完全区组所需的处理。
Based on multi - factor orthogonal designed field experiment , the ridge regression models of seed yield components and seed yield of the 6 grass species are founded through ridge regression analysis with big samples 摘要采用多区组多因素正交试验设计,通过大样本岭回归分析求出6种禾本科牧草种子产量因子与产量的岭回归模型。
The confounding design and the balanced incomplete block design were introduced from the fundamentals of special design , which may be applied to the experiment with fewer homogeneous experimental units and more treatments 根据特种设计的基本原理,介绍了用混杂设计、平衡不完全区组设计以实施基因型同质试验单元较少而处理数较多的试验。
22 varieties that breed in different ages and foreign good quality varieties were used to do varietal comparative trial of randomized blocks and to analysice 11 cooking and eating quality properties and taste value of used rice varieties 选用22个品种,进行了随机区组的品种比较试验,并分析了供试品种的11项蒸煮食味品质特性及味度值。
