分级的

Usually, there are three main important forces acting on particles in a classification tower: gravity, flotage and dragging force.

将该设备用于固体颗粒的分级，取得了显著的分级效果，展现了广阔的应用前景。

The gradation of the means is like that of the ends a process of preferring a to b.

手段的分级像目的的分级一样，是一个甲优於乙的过程，涉及取与舍。

Eggs with cracks and leaker are a major issue as they degrade all the mechanical parts while processing on the graders and packers, but at the small ones which are present in most poultry farms.

裂纹蛋和破损蛋在鸡蛋加工中是非常严重的问题，因为它们能够在分级和包装过程中污染机械部件，进而导致鸡蛋级别下降，因而在鸡蛋被运往分散于各个地方，设备昂贵的鸡蛋分级包装厂之前，剔除有严重缺陷的鸡蛋显得尤为重要。

While about 80 percent of parents use the MPAA's ratings system, the number drops precipitously for TV ratings, where as few as 39 percent of parents said they used them.

尽管80%的家长使用MPAA的分级系统，这一数字在电视分级上急剧下降，只有39%的家长表示他们使用这一系统。

However, the transformation rate from dominant stem to overtopped stem and from overtopped stem to dominant stem were the lowest. The interconversion of classified stem would increase as the stand density and the rate of L. gmelinii was going up. The altitude that classified stem mainly concentrated was less than 1000m, slope was less than 25°, aspect was south slope, position was at middle and lower, soil depth less than 17cm. The rate of no interconversion was 66.7% among overtopped stem. It should cut the overtopped stem as intermediate cutting.

优势木转被压木和被压木转优势木的转换率最低；随着林分密度和林分中落叶松比例增加，分级木相互转换数也增多；分级木转换现象主要集中在海拔＜1000m、坡度＜25°、坡向为阳坡、坡位为中下、土壤厚度＞17cm的林分中；被压木中，无转换的占66.7%，抚育采伐时应考虑伐除这些被压木。

In light of the problem of describing nonlinear rheology of rock and soil with principle of linear superposition, a neural network model for rheology of rock and soil under step loading has been established with artificial neural network instead of traditional mathematical and mechanical methods.

针对分级加载下用线性叠加原理来描述岩土非线性流变存在的问题，采用人工神经网络方法代替传统数学力学方法，建立了分级加载下岩土流变的神经网络模型，并且对具体岩石的蠕变试验曲线进行了模拟。

Spearman rank correlation, Kappa test and regression analysis were applied.

视觉分级间的相关性评价采用Spearman等级相关分析，不同评估者之间的一致性分析采用Kappa检验，通过回归分析计算各分级间相互转化的参数。

Critics of the reclassification program say the Central Intelligence Agency and other U.S.

对再分级计划持批评意见的人称中央情报局和美国其他的间谍机构是将档案重新分级计划的幕后主要策动者。

Double—blind, randomized, placebo—controlled clinical trail on Chronic Congestive Heart Failure with Shengmai capsule treatmentResult:5.1 The left room shoots the blood score EF value:EF value three hour point total to distribute the characteristic obeys positive the normal distributes, proceeding the independent sample t examination: diagnosing moment hour point an EF value variety of placebo group and treatment group have no to show the difference of obvious; 12 weeks with 24 week hour point, an EF value variety of placebo group and treatment group also have no to show the difference of obvious.

两组EF值再分别作自身前后对照——配对样本t检验：安慰剂组在就诊时分别和试验12周、24周进行对照，发现其自身前后的EF值并无显著性差异(P＞0.05)；治疗组也作同样对照，虽然EF值在三个时点的变化均无显著性差异(＞0.05)。5.2 NYHA心功能分级安慰剂组和治疗组治疗前后的非参数检验——Wilcoxon检验：两组治疗前后心功能分级对照无显著性差异(＞0.05)。

Another is the moving characteristics of particles in different cases.If the dispersity of ultra-fine powder is improved,and the classification field of force is designed corr...

如果提高超细粉体的分散性，按照粒子的运动特性设计出合理的分级力场，将有助于提高分级效果。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
