乘法

For that reason, it is often helpful to look at subtraction as addition of the minuend and the opposite of the subtrahend, that is a b = a +.

乘法运算具有交换性和结合性；进而，它对加法和减法运算具有分配性。

The author mainly realized the method of generating the large random numbers and judging the prime number using Lehmann means,then three pairs of secure key with different lengths (256 bits,512 bits,1024 bits) was generated to meet the demand of different security grade. In encryption module,modular multiplication arithmetic of large number was realized adopting addition chaining. In decryption module,extended Euclid was used to get inverse,and the Chinese remainder theorem was used to realize decryption,which increased the speed of decryption greatly.

作者主要实现了大随机数的生成、采用整除小素数和勒曼测试法判定素数，可以生成三种不同长度的密钥对(256位、512位、1024位)来满足不同的加密安全等级的需求；加密模块中，选用了二进制序列的乘法方法，实现了大数模幂乘运算；解密模块中，引用了扩展的欧几里德法求逆元，并采用中国剩余定理实现解密过程，大大提高了解密速度。

A"bit-mismatch"squarer and a"digit-serial"polynomial multiplier have been designed for finite field arithmetic and the modular inverse in GF (2〓) can be calculated under the combination of the squarer and the multiplier. Based on the Montgomery method for the elliptic curve scalar multiplication, a new improved process has been put forward in the thesis.

论文改进了标量乘法Montgomery算法流程，利用寄存器间的数据交换，将0和1两种情况下的中间结果"点加一倍点"操作统一起来，简化了控制流程，使关键路径延时下降，而且减少了运算单元输入输出的连线逻辑。

The ion-interaction parameters of HCl in 0.1-16.0 molality at 25℃ and the ions-interaction parameters of 2-spices and 3-species between H and M and among H、M and Cl were presented and evaluated.

本文报道应用Pitzer的离子相互作用模型，系统地对0.1-16.0 mol.kg-1浓度范围内HCl的活度系数和渗透系数值进行最小二乘法拟合，得到一套优于文献上报道的作用参数。

Cassiodorus was the first to make the transcription of manuscripts and the multiplication of books an organized and important branch of monastic labour, but his insistence in this direction influenced western monachism enormously and is in fact his chief claim to recognition as a legislator for monks.

cassiodorus是第一次，使转录的手稿和乘法的书籍，有组织的重要分支寺院的劳工，但他坚持在这个方向的影响，西方monachism很大，其实是在他的行政索赔的承认，作为一个立法者为僧侣。

During the five years that we would live with my stepfather in Indonesia, I was sent first to a neighborhood Catholic school and then to a predominantly Muslim school; in both cases, my mother was less concerned with me learning the catechism or puzzling out the meaning of the muezzin's call to evening prayer than she was with whether I was properly learning my multiplication tables.

在我与继父生活在印尼的5年里，我最初被送去附近的天主教学校上学，然后被送去占主导地位的穆斯林学校；在我就读这2种学校时，我母亲对我学习天主教教义问答或是我对宣礼员召唤晚祷含义的思索的关注，和关心我是否正确地学习乘法表是一样的。

While dealing with the multicollinearity of design matrix X , the ordinary least squares estimation is always helpless.

基于最小二乘法处理病态阵X共线性问题上的不足，线性有偏估计是改进最小二乘估计最直接的方法。
