查询词典 divisor of zero

The reason that zero can not be divisor, is right?Feng XinkongIn the eighth book of six-year primary school's teaching in nine-year compulsory educationmaterials, it states that "zero can not be divisor". But we can find that the formula, a=cq, checking the dividing exactly , is same as the form of direction proportion function, y=kx; the formula of checking the dividing not exactly, a=cq+r, is same as the form of simple function.

在九年义务教育六年制小学教科书《数学》第八册中规定"零不能作除数"，但是当我们学习了正比例函数和一次函数之后就会发现，验算能整除的除法的关系式a=cq和正比例函数y=kx的表示形式相同；验算有余数除法的关系式a=cq+r与一次函数的关系式y=kx+b的表示形式相同。

In this dissertation , the main works of the author is follows:(1)The method FPI (Fast Plaintext Imbedded to the divisor) is improved, which makes the probability of the plaintext not be imbedded into the divisor nearly to zero and its velocity is fast.

在本论文中，作者主要做了以下几个方面的工作：(1)改进了明文嵌入超椭圆曲线除子的FPI(Fast Plaintext Imbedded to the divisor)方法，该方法使明文不能嵌入到超椭圆曲线的除子的概率几乎为零，且其速度较快，可用于椭圆曲线密码体制。

An ring R is said to be the middle superprime ring, if every non - zero ideal of R contains an non - zero element c, which is not middle divisor of zero.

一个环R称为中间超素环，如果它的每个非零理想都包含一个非零元素，它不是中间零因子。

A Sichuan party leader said on an official website that Beijing's directive meant no less that ensuring zero tolerance to protesters, that "zero petitioners go to Beijing, zero go to provincial capitals, there are zero group petitions and zero mass incidents".

在一个官方的网站上一位四川的党委领导人说，北京的方针是确保对抗议者绝不姑息，那就是&无进京上访者，无上省会上访者，无集体上访事件，无大规模事件&。

This paper introduced the odd sieve sequence, the methods of character, estimate and triangle sum are used to study the mean value of the divisor function. An asymptotic formula of the divisor function is gave in the odd sieve sequence set to through the analytical method.

引入了奇筛数序列，主要利用特征和估计及三角和方法，研究了除数函数的均值性质，并通过解析方法给出了除数函数在奇筛数序列集合中的一个的渐近公式。

Using properties of zero-divisors, regular elements and subdirectly irreducible ring , we obtain some results on the commutativity of semi-prime ring and Jacobson semi-simple ring as follows 1 Let R be a semi-prime ring ,a∈R and 2a is not zero-divisor,If R satisfies one of the conditions in this paper , then R is commutative.

在某些特殊环的交换性方面取得了进一步的结果，并得到了一些新的结论，主要有一设R 为半质环，a∈R ，且2a 为非零因子，如果R 满足论文中八个条件之一，则可以证明环R 为交换环。

In mathematics , a division is called a division by zero if the divisor is zero . Such a division can be formally expressed as a /0 where a is the dividend. Whether this expression can be assigned a well-defined value depends upon the mathematical setting. In ordinary arithmetic, the expression has no meaning .

如果某一上市公司宣布派发红利股份、红利认股权证、以折让价供股或派发其它有价权益，在除权日之前一日持有它的股票的人士可享有该等权益，在除权日当日或以后才买入该公司股票的人则不能享有该等权益。

The results show that the zero speed point is located on the arc between two absolute speed zero points of rotation axes, and the necessity of relative speed zero point is demonstrated, From the location of speed zero point, some useful conclusions can be drawn.

对速度零点的位置进行了分析，得出了如下结论：对于一定形状的工件，通过调整两轴的转速比以及两轴夹角参数，可以将速度零点置于工件之外，从而避免速度零点对研磨的不利影响。

With the help of computer program, zero speed point was searched. The results show that the zero speed point is located on the arc between two absolute speed zero points of rotation axes, and the necessity of relative speed zero point is demonstrated.

利用程序对相对速度零点的位置进行搜索，发现速度零点处于两轴绝对速度零点之间的圆弧上，从而证明了相对速度零点存在的必然性。

A cycle is one complete reversal of an alternating current or voltage from zero to a positive maximum to zero again and then from zero to a negative maximum to zero again. The number of cycles per second is the frequency.

周期周期是指交流电流或电压从零到正最大值再到零，然后从零到负最大值再到零这样一个往复的过程；而频率则是指每秒可完成的周期数。
