A term applied to a storage medium that permits data to be removed , leaving the medium in a condition to receive new data . magnetic tape , for example , is " erasable " and paper tape is not . the term is also applied to a read - only memory ( integrated circuit ) that can be reprogrammed by the user 用来修饰说明某种存储媒体，可以将其存储的数据除去，以便存储新的数据。例如磁带是可擦除的，纸带是不可擦除的。该术语也用于可重新编程的只读存储器（集成电路） 。
An instruction in machine language generally tells the computer four things : ( 1 ) where to find one or two numbers or simple pieces of data in the main computer memory ( random access memory , or ram ) , ( 2 ) a simple operation to perform , such as adding the two numbers together , ( 3 ) where in the main memory to put the result of this simple operation , and ( 4 ) where to find the next instruction to perform 机器语言中的一条指令通常告诉计算机4件事情： （ 1 ）到计算机主存储器（随机访问存储器）的哪个位置去找一或两个数字或者简单的数据段； （ 2 ）要执行的一个简单操作，例如将两个数字加起来； （ 3 ）将这个简单操作的结果存放在主存储器的什么位置；以及（ 4 ）到哪里找要执行的下一条指令。
Domestic and foreign researchers paid their focus on those more flexible , effective and general fixtures . in according with the above - mentioned problems , professor li beizhi put forward an untraditional technology of workpiece installation and a general fixture system with initiative location and state memory ( il & sm ) 针对以上问题，李蓓智教授等提出了一种非传统的工件安装技术和能够主动寻位与状态记忆的通用夹具系统( initiativelocationandstatememory ? il & sm ) 。
Today km bases on the ontology which provides the terminology shared and understood unanimously by all the people concerned , and establishes a organizational memory ( om ) . om changes the unstructured and semi - structured information into the structured knowledge items by annotating all kinds of information with the explicit explanation in a semantic way , and it gives the efficient means to store and retrieve them 现代知识管理以本体论提供的共享、理解一致的术语为基础，建立组织记忆( om ) ，对企事业关注的各种信息体作语义清晰的说明，将非结构化、半结构化的信息体转化为含结构化存储的知识项，并提供高效的存取结构。
The kanerva ' s sparse distributed memory ( sdm ) tackles the problem of training large data patterns and extendes the storage mode of existing computer . but it ' s address array produced randomly ca n ' t reveal the distribution of patterns and it has ' t the ability of function approximation for its learning rule Kanerva的稀疏分布存储( sdm )模型解决了大维数样本的训练问题，推广了现有计算机的存储方式。但其地址矩阵的随机预置方式不能反映样本的分布，并且sdm的学习方式使之不能用于函数逼近及时间序列预测问题。
Magneto - electronics lies in the area of current scientific interest in condensed matter physics and material sciences , due to abundant physical conceptions and applied potentials . it is a base of magnetic devices with high density and sensitivity . recently , non - volatile magnetic computer memory ( mram ) is expected to have a large economic impact , and has been significantly focused on its experimenatal research 目前，非挥发性磁存储记忆器件?磁存储器magneticrandomaccessmemory ( mram )的研究和开发已成为自旋电子学研究的主要应用目标；而在室温和低磁场下，具有足够大的磁电阻( mr )效应成为实现mram器件应用的前提。
In order to fulfill the research , we firstly measured ol by knowledge acquisition ( ka ) , information dissemination ( id ) , information interpretation ( ii ) , and organizational memory ( om ) , and ed by technological and market dynamics . in this dissertation , questionnaire was used as research instrument during the data collecting 为了研究这些问题，我们首先分别对组织学习和环境动态性进行了测度，用知识获取、信息分发、信息解释和组织记忆度量组织学习能力，用技术发展和市场需求动态性表征环境的动态性水平。
