查询词典 scalar product

First, characteristics of product models in traditional design and concurrent design are compared. Therefore, thoughts of design object and design process working in the double harness are put forward. And, two typical representation methods of product model, and their localization are expatiated. Concept of generalized engineering semantic feature is defined. State of product design model is expressed. Then, an integrated representation method of product model is advanced. Based on the Pro/Engineer software platform, product-modeling system for product general information model is set up.

首先，分析和比较了传统设计与并行设计中产品模型的特点，提出了并行设计中同时考虑设计对象并行与设计过程并行的思想；在阐述两种典型产品模型表示方法，分析其片面性的基础上，引入了广义工程语义特征的概念，表达了产品设计模型的状态，提出了一种集成的产品模型表示方法；基于Pro/E软件平台，建立了产品广义信息模型建模系统。

In this paper, we introduce the algorithm of Schoof-Elkies-Atkin to compute the order of elliptic curves over finite fields. We give out a fast algorithm to compute the division polynomial f〓 and a primitive point of order 2〓. This paper also gives an improved algorithm in computing elliptic curve scalar multiplication. Using the method of complex multiplication, we find good elliptic curves for use in cryptosystems, and implemented ElGamal public-key scheme based on elliptic curves. As a co-product, we also realized the algorithm to determine primes using Goldwasser-Kilian's theorem. Lastly, the elliptic curve method of integer factorization is discussed. By making some improvement and through properly selected parameters, we successfully factored an integer of 55 digits, which is the product of two 28-digit primes.

本文介绍了计算有限域上椭圆曲线群的阶的Schoof-Elkies-Atkin算法，在具体处理算法过程中，我们给出了计算除多项式f〓的快速算法和寻找2〓阶本原点的快速算法；标量乘法是有关椭圆曲线算法中的最基本运算，本文对[Koe96]中的椭圆曲线标量乘法作了改进，提高了其运算速度；椭圆曲线的参数的选择直接影向到椭圆曲线密码体的安全性，文中利用复乘方法构造了具有良好密码特性的椭圆曲线，并实现了椭圆曲线上ElGamal公钥体制；文中还给出了利用Goldwasser-Kilian定理和椭圆曲线的复乘方法进行素数的确定判别算法；最后讨论了利用椭圆曲线分解整数的方法并进行了某些改进，在PC机上分解了两个28位素数之积的55位整数。

For this reason the inner product is called also the scalar product .

为此，内积也叫做纯量积。

The dot product, being the product of three scalars, is a scalar.

We also show that thc linking C~*-algcbra of the TRO-univcrsal free product of two TRO\'s is~*-isomorphic to thc universal free product of the linking C~*-algcbras of thc two TRO\'s.In addition, inspircd by thc concept of full amalgamated frcc product of C~*-algebras, by using thc full amalgamated free product of thc linking C~*-algcbras of ternary rings of operators,we introduce the definition of TRO-full amalgamatcd free product,and give its construction,which is provcd to satisfy the univcrsal propcrty.

另外，受C~*-代数全融合自由积概念的启发，利用算子三元环的连接C~*-代数的全融合自由积，本章把全融合自由积的概念扩展到了算子三元环上，引入了算子三元环全融合自由积的定义，给出了它的一个构造，证明了这种构造(来源：ABC论文3b3b3b网www.abclunwen.com)的确具有"泛性质"，并且证明了两个算子三元环的TRO-全融合自由积的连接C~*-代数*-同构于这两个算子三元环的连接C~*-代数的全融合自由积。

With the increasing of the concentration of alkali, the content of insolubility of the product reduces initially but increases later, the DS of product increases initially then reduces later. The product has good solubility and high DS at 10% content of alkali. The insoluble product reduces at initially and then keeps stability later with the time of basification extending. With the increasing of the content of water in system, theinsolubility of the product reduces initially and then increases later.

随着碱浓度的增加，产物中水不溶物含量先降低后增加，取代度先上升后下降，在10％时，水溶性最好，取代度最高；延长碱化时间，产物中水不溶物含量下降，之后趋于稳定；提高反应体系中水的含量，产物中水不溶物含量先降低后增加，在7％时，水溶性最好，延长分散时间，产物中水不溶物含量下降，取代度提高；醚化剂以少量多次的方式滴加，产物水溶性好。
