加法

The purpose is to inspect the grade differences on time of mental addition and mental subtraction of pupils from three grades as well as grades differences of arithmetic time and integration time. The results show that mental arithmetic time of pupils from Grade 2, 4 and 6 decreases with the increase of grades.In the non-carry mental addition of 1-digit number and multi-digit number, menta...

研究结果表明，2、4、6 年级小学生口算时间随年级的增高而减少；在一位数加多位数不进位加法口算中，口算时间差异主要源于运算时间差异和整合时间差异；在一位数加多位数进位加法口算中，口算时间差异源于运算时间差异；在多位数减一位数不借位减法口算中，运算时间年级差异不显著，而整合时间存在显著的年级差异；在多位数减一位数借位减法口算中，口算时间的年级差异主要表现为运算时间的差异，而整合时间差异不显著。

P×P and P were two major non-Bayesian algorithms. 6 Less than 25% of the participants used frequency. In those who got other results except P , much more people used probability. Experiment 2 had a randomized multigroup posttest design. There was only one factor named implied condition which had five levels: not imply, imply P, imply addition, imply division and imply all. The results showed that: 1 All the implied conditions significantly improved the participants' performance. When under the condition of implying division, the participants derived the best results. 2 31.9% of the participants got correct answer, 73% of who used frequency to rewrite the information. 3 78% of the participants could apply one or several of the four concepts: probability of "not the event", multiplication rule, addition rule and condition probability.

结果表明：1 被试的估计受问题内容的影响，权威型问题情境容易使被试高估，非权威型问题情境使被试的高估现象大大减少；数据结构和提问形式对被试估计不产生影响。2 有近5%的被试能正确估计P，其中 73%使用频数对信息进行再表征。3 贝叶斯推理中各分步骤的困难程度由低到高分别是：乘法、P、加法、除法。4 有50%的被试能运用对立事件概率、概率乘法、概率加法、条件概率这四个概念中的一种或者几种。5 使用最多的两种非贝叶斯算法是P×P和P。6 不到25%的被试使用频数；求得除P以外各类结果的被试中，使用概率的人数远多于使用频数的。

Sometimes, I also counted as the adder multiplication, the multiplication operator adder into it!

有时候，我还会把加法算成乘法，把乘法算成加法呢！

In practical terms, an octonion is simply an octuple of real numbers

定义在八元数上的加法和乘法运算推广了在四元数上的加法和乘法运算。

In this paper, an effective and practical procedure in time domain,the real mode-superposition method,is proposed.

本文给出一种有效而实用的时域解法———实模态叠加法，此外还介绍了复模态叠加法。

T"、 come under ts, ts", s, front—rhonchus vowels and back—rhonchus vowels incorporate, becoming nasal vowels, and so onAbout grammar,the article chiefly describes word-building and word classes, which embody the characters of Ying County dialect"s grammar.word-building includes: the divided-syllable words and the combined -syllable words, superposition、 the suffix of "Er"、 the suffix of "zi、 affix.

t'、归入舌尖前音ts、ts'、s，前鼻音韵母和后鼻音韵母合流为鼻化韵等。语法方面，本文主要描写了最能体现应县方言语法特点的构词法和词类。应县方言构词法主要有：分音词与合音词、重叠、儿化、"子"尾、附加法。其中，附加法描写分析了应县方言的一些特殊构词词缀，如"货"、"猴"、"鬼"、"圪"、"忽"、"达"等。

In vector algebra, addition are defined to add coordinates entries respectively,and this system of operation is the direct sum Z Z={|a,b are integers} of integers ring Z,the operations are+=,=.

向量代数加法就是这样按照分量加法在运算，再加上按照分量的乘法，这个运算体系就是整数环Z的直和Z Z={|a，b为整数}，其上的运算就是+=，=。

On the other hand, the known number in addition becomes the unknown number in subtraction.

在加法中是已知的，在减法中变成未知的；在加法中是未知的，在减法中变成已知的。

Depending on the structural feature of the discernible vector, a plus rule for the discernible vector sets was defined, and a scan vector with concise structure but representing the information table can be obtained through scanning the discernible vector just one time.

根据粗糙集理论知识，定义了一个新概念―差别向量，利用差别向量将信息表转换成差别向量组；根据差别向量的结构特征，定义了差别向量加法法则；运用这个加法法则仅需对差别向量组扫描一次，就可以形成结构简洁却能代表原信息表属性特征的扫描向量。

There was no significant gender difference.4. The correlations of latencies and errors were significant between addition and subtraction.

加法的反应时和减法的反应时之间存在着极强的正相关关系，加法的错误率与减法的错误率之间也存在着较强的正相关关系。
