| 1. | Dispersion refers to the spread of the data, that is the extent to which the observations are scattered . 离散性是指数据的分散程度,即观察值散布的范围。 |
| 2. | To increase our understanding of the pattern of the data, we must also measure its dispersion-its spread, or variability . 为了加深对数据特征的全面理解,还必须度量它的离散性,即数据的分散程度或变异程度。 |
| 3. | The standard error of estimate, on the other hand, measures the variability, or scatter, of the observed values around the regression line . 而估计值的平均误差,却是度量观察值围绕着回归直线的变化程度或分散程度。 |
| 4. | Therefore , other metrics may be used to describe the degree of spread of the variable 因此,其它测量也可能被用来描述一个变量的分散程度。 |
| 5. | Method for the assessment of the degree of pigment or carbon black dispersion in polyolefin pipes , fittings and compounds 聚烯烃管道配件和复合物中颜料或炭黑分散程度的评估方法 |
| 6. | The insecticide application of 25 % thiamethoxam wdg , 5 % fipronnil sc , 25 % buprofezin wp 10 % beta - cyperethrin lc , and 25 % phoxim lc on piemarker plants , showed different control effects on sucking insect pests in cotton fields 苘麻植株在田间分散程度和诱集效果呈正相关,单棵插花种植苘麻的诱集效果分别是片状种植和条带种植苘麻的7倍和3倍。 |
| 7. | Statistic data of die last few years in the a - share market indicate that the premium of control of shell companies is about 25 percent over the net assets on average , although it varies in a wide range case by case 对于买壳上市而言,确定壳公司价值的关键是确定控制溢价。影响控制溢价高低的因素主要有壳公司的股本大小、股权分散程度、持股比例、资产专业化程度、资产的结构、支付方式等。 |
| 8. | The results showed that the conductivity of conductive carbon black / polymer composite mainly depended on the surface property , structure and content of conductive carbon black and the dispersing extent of the aggregate of conductive carbon black in polymer 实验结果表明,导电炭黑高分子聚合物的导电性主要取决于不同级别的导电炭黑的表面性和结构等特性、炭黑的不同用量以及导电炭黑的聚集体在高分子聚合物的分散程度。 |
| 9. | The mechanical properties indicated that the improved exfoliation degree of mmts was essential for better properties of the nanocomposites , while the mechanical properties of interc alated nanocomposites were dependent on the structure of the organic modifiers 3 有机蒙脱土层间有机物含量较高,有利于聚合物插层和mmt片层剥离分散。片层剥离分散程度大,有利于提高复合材料的力学性能;插层型复合材料的力学性能与表面活性剂分子结构有关。 |
| 10. | The cementing metal and carbon nanotubes ( cnts ) were added into the milled solid solution of w - c . by ball milling not only the additives were well dispersed in the the powder but also the size of cementing metal crystal was reduced , which was in favor of the reinforcement of alloys 在w _ ( 50 ) c _ ( 50 )球磨制得的粉体中直接加入粘结金属和碳纳米管,利用高能球磨混合,提高它们在粉体中的分散程度的同时可以进一步减小粘结相的晶粒尺寸,有利于提高材料性能。 |
