分数

Please say out decimal if you hear fraction, then exchange.

老师说分数，同学们说小数，老师说小数，同学们说分数

The percentage of correct answer of mathematics learning-disabled students in addition, subtraction, multiplication, and division of fraction and decimal is lower than that of normal students.

在带分数乘以整数的分数来法中，数学学习障碍学生只做整数部分的相乘忽略分数部分。

The converting of a fraction to its decimal equivalent.

分数化成小数：把分数写成与之相等的小数

Decimal divided by fraction, When there's a multiple relationship between decimal and fraction, we can use reduce fractions.

小数除以分数，当小数与分数的分子有倍数关系时，可用直接约分法。

The diameter of the bore of a firearm, usually shown in hundredths or thousandths of an inch and expressed in writing or print in terms of a decimal fraction

口径：火器枪孔的直径，常以英寸的百分数或千分数表示，在手写或印刷中常以十进制分数表示

The first section is to introduce some corresponding basic definiens and properties on the fractional calculous. The rest of the chapter is to present solving methods for the approximation solutions of the nonlinear fractional differential equations and their application.

首先介绍了本章涉及到的分数微积分的定义及其性质，然后介绍了非线性分数阶微分方程近似求解的方法及其应用。

The performance of traditional particle filter would be degenerate in alpha stable distribution noise.A new fractional lower order particle filter based on fractional lower order model was presented in this paper,and the detailed operation algorithm was proposed.

在alpha稳定分布噪声下，传统的基于二阶模型的粒子滤波器性能会出现退化，文章提出了一种基于分数低阶模型的分数低阶粒子滤波器，并给出了具体的运算公式。

Their sum becomes the denominator of fractions that are applied against the depreciable cost of the asset in allocating the total depreciation over the estimated useful life.

它们的总数就成为用于按预计使用寿命分配折旧总额的资产的折旧费用的分数的分母，分数的分子就是资产预计使用寿命相反顺序的单个年数。

The numerator in this fractional designation is known as the diametral pitch and controls the pitch diameter; the denominator, which is always double the numerator, is known as the stub pitch and controls the tooth depth.

在这一系列的分数中的分子是径节，径节的大小决定了节圆的直径；而分数中的分母通常是分子的两倍，分母是残余径节，它的作用是控制齿槽的深度。

Tooth Proportions.—There are 17 pitches: 2.5/5, 3/6, 4/8, 5/10, 6/12, 8/16, 10/20, 12/24, 16/32, 20/40, 24/48, 32/64, 40/80, 48/96, 64/128, 80/160, and 128/256. The numerator in this fractional designation is known as the diametral pitch and controls the pitch diameter; the denominator, which is always double the numerator, is known as the stub pitch and controls the tooth depth. For convenience in calculation, only the numerator is used in the formulas given and is designated as P. Diametral pitch, as in gears, means the number of teeth per inch of pitch diameter.

齿比——一共有17种齿比：2.5/5，3/6，4/8，5/10，6/12，8/16，10/20，12/24，16/32，20/40，24/48，32/64，40/80，48/96，64/128，80/160和128/256在这一系列的分数中的分子是径节，径节的大小决定了节圆的直径；而分数中的分母通常是分子的两倍，分母是残余径节，它的作用是控制齿槽的深度为了方便计算，在所有的公式中都使用分子作为计算参数，并且与齿轮的表示方式一样定义为径节P尺寸，也就是在节圆上，每英寸长度上的齿数

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。
