His "aha insight" was a realization that a arithmetic system did not have to obey the commutative law .

他的"啊哈，灵机一动"将算术领域不用遵循互换律的设想成为了现实。

The so-called " natural " arithmetical operations retain commutativity at the expense of continuity.

所谓的"自然"算术运算以损失连续性的代价保持了交换律。

This thesis investigates some arithmetic problems with cryptographical background in finite fields and and consists of four chapters.

本文主要研究了有限域上的一些算术问题，这些问题均具有密码学上的应用背景。全文共分四章。

METHODS: Arithmetic mean and constituent ratio etc were used as indices to describe the current level of drug expense, and Mann - Whitney test and multivariate linear regression model were applied to compare the difference in drug expense between inpatients with and those without medical insurance.

以算术平均数和构成比等指标描述急性阑尾炎患者的药品费用水平，利用秩和检验与多元线性回归模型等方法比较"医保"患者和自费患者的药品费用。

Modern algorithms for arithmetic (both for hand and electronic computation) were made possible by the introduction of Arabic numerals and decimal place notation for numbers.

阿拉伯文数字基于算术是由伟大的印度数学家Aryabhatta ， Brahmagupta和巴斯卡拉一Aryabhatta尝试不同的地方价值符号和Brahmagupta补充零印度一些系统。

Thus, there is no way to demonstrate that sufficient data has been collected to form a mathematically valid approximation (or known degree of approximation) of the complete data set.

因此， 没有方法示范充份的数据已经被收集形成完全数据组的一个算术有效近似值。

About this, Pierre de Fermat wrote in 1637 in his copy of Diophantus's Arithmetica,"I have discovered a truly remarkable proof but this margin is too small to contain it."

G.Bachet所翻译的丢番图《算术》中写道︰「我已发现了一个真正不凡的证明，但页边太小，写不下。

Its actual birth isusually credited to Diophantus of Alexandria, who wrote "Arithmetica" in Greekduring the third century.

而它真正的诞生通常归功于公元三世纪的希腊人丢番图，他著有《算术》一书。

The signal test table is established where the Labview signal collection system collects the concrete exit pressure signals, the piston displacement signals of concrete cylinder and the main hydraulic signals. The real measured signals are processed through arithmetic equilibrant filter of the data signal processing method. The pumping efficiency and relative error of real time output are measured by two output calculation methods.

搭建了实测信号试验台，通过Labview信号采集系统现场采集混凝土出口压力信号、混凝土缸活塞位移信号和主液油信号，采用算术平均滤波法的数字信号处理方法对实测信号进行处理，通过两种排量计算方案检测泵车实时排量的泵送效率和相对误差。

However, most computers have circuits for performing arithmetic operations, such as: addition, subtraction, division, multiplication and exponentiation.

电脑有许多显著的功能，然而，许多电脑都有用来进行算术运算的电路，如加、减、乘、除、求幂。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。

The factory affiliated to the Group primarily manufactures multiple-purpose pincers, baking kits, knives, scissors, kitchenware, gardening tools and beauty care kits as well as other hardware tools, the annual production value of which reaches US$ 30 million dollars.

集团所属工厂主要生产多用钳、烤具、刀具、剪刀、厨具、花园工具、美容套等五金产品，年生产总值3000万美元，产品价廉物美、选料上乘、质量保证，深受国内外客户的青睐
