减法

The proposed method first uses common subtractive clustering locating method to acquire video object position and moving object number of each frame. Then, the proposed algorithm uses fuzzy C-means clustering algorithm to further cluster the moving object foreground pixel samples. Finally, matrix analysis theory for calculating eigenvalues and eigenvectors of covariance matrix is applied to compute the object scale and orientation parameters.

该算法在减法聚类算法预定位目标位置及获得目标个数的基础上，进一步采用模糊C均值聚类对目标前景样本进行归类，最后通过对目标前景样本协方差矩阵特征值和特征向量的分析获得目标的尺度及方向参数，从而实现对视频运动目标的定位。

Op1 + op2 The addition operator will add two numbers. op1 - op2 The subtraction operator will subtract two numbers. op1 * op2 The multiplication operator will multiply two numbers. op1 / op2 The division operator will divide two numbers. op1 % op2 The modulus operator will return the remainder of the division of two integer operands. op1 xx op2 The exponentiation operator will raise op1 to the power of op2.++op1 The pre-increpment operator will increase the value of op1 first, then assign it. op1++ The post-increment operator will increase the value of op1 after it is assigned.--op1 The pre-decrement operator will decrease the value of op1 before it is assigned. op1-- The post-decrement operator will decrease the value of op1 after it is assigned.

op1 + op2 对两个数值做加法操作 op1 - op2 对两个数值做减法操作 op1 * op2 对两个数值做乘法操作 op1 / op2 对两个数值做除法操作 op1 % op2 求两个整型数值的余数 op1 xx op2 求幂操作：求 op1 的 op2 次幂++op1 前加操作： op1 的值先增加，然后将值赋给自身 op1++后加操作： op1 的值先赋给自身，再增加值--op1 前减操作： op1 的值先减少，然后将值赋给自身 op1—后减操作： op1 的值先赋给自身，再减少值

Expressions are normally comprised of parenthetical expressions, and are evaluated in a certain order (from innermost to outermost, parenthesis first, then multiplication, division, addition, subtraction, et cetera).

表达式就是数学的语言，他们是返回一数据的字符组合，表达式通常是由附加说明的和被求的值在一个命令（来自圆括号里的、乘法、除法、加法、减法等）。

The error percentage of mathematics learningdisabled studnets in addition, subtraction and multiplication of fractions is higher than that of normal studnets.

无论是分数的加法、减法和乘法的计算，数学学习障碍学生犯错误率高於普通学生。

Methods The RCAⅠidentifying Terminal Galβ14 GlcNAc glycoprotein was acquired by RCAⅠ(Ricinus communis agglutininⅠ) affinity chromatography method from nor mal person serum and was marked by the horseradish peroxidase.133 tumor patients,64 benign disease patients and 240 normal person serums were detected by the subtraction of agglutinin.

应用RCAⅠ亲和层析法从正常人血清中获得RCAⅠ相关末端Galβ14GlcNAc糖蛋白，用辣根过氧化物酶标记，采用凝集素差减法，对133例肿瘤患者，64例良性疾病患者和240例正常人血清进行检测。

Firstly,"clean steel" areas are identified and the steel composition determined. In the second step, the average composition across the entire length of the scan is determined. In the final step, the average slag composition is determined by means of a difference calculation.

首先，辨别出"干净"的钢区域，测定出钢的成分；第二步，测定出扫描总长度范围内的平均成分；最后一步，通过差减法计算出炉渣的成分平均值。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
