存取时间

Access speed of disk is the key to database performance.

减少磁盘的存取时间是提高数据库性能的关键。

Which is only a 28 percent slowdown in memory access time.

这只把内存存取时间降低了28%。

Even within a hierarchy level such as DRAM, the specific row, column, bank, rank, channel, or interleave organization of the components make the access time variable, although not to the extent that rotating storage media or a tape is variable.

即使在一个层次的水平，如内存，具体的行，列，银行，职级，渠道，或交错的组织成分使存取时间变量，但不转动的范围内存储介质或磁带是可变的。

The resulting system 1 maintains or improves CPU utilization rates as CPU speeds increase, 2 provides large level 1 caches while maintaining cache access times of one CPU clock cycle, and 3 provides high CPU utilization rates for those processing applications where locality of memory references is poor (e.g., networking applications).

随着CPU速度的提高，能够保持或提高CPU的利用率，2）提供大容量一级高速缓存，并同时保持高速缓存的存取时间为一个CPU时钟周期，3）为那些存储器引用局部性不强的处理系统提供高的CPU利用率。

Compared with primary storage,the storage capacity of a DASD is larger and the cost per bit stored is lower.although the access time of a DASD may be only a few milliseconds,primary storage,primary storage speed is thousands of timer faster.different DASDs provide different levels of cost and performance.

与主存储器相比，DASD的存储容量更大，每存储位的花费更低。尽管DASD的存取时间只为几毫秒，而且主存储器的速度比之快几千倍。不同的DASD其成本和性能的等级也不同。

Proposed methodology for estimating the ratio of on-chip computation time to off-chip access time can be applied on defacement platforms. On our experiment platform, average error of estimations is less than 8%.

修改并发展出一套完整的方法论，在不同的平台下都可以用类似的方式来估算记忆体存取时间以及处理器计算时间的比例，其误差在本论文的实验环境下小於8%。

Access Time: is the average time to read a random sector on the disk, analogous to latency response time.

存取时间：是的平均时间读取磁盘上的随机部门，类似于延迟响应时间。

Media capable of storing programs and data so that the time needed to access specific elem ts is quick and independent both of their location , and of the location of the last data element accessed.

能够 存储程序和数据的介质，存取某些指定单元所需的时间很短，并且既与它们的位置无关，也与前一个存取的数据单元的位置无关。

We refer to an accurate DVFS algorithm which calculates proper frequency of a program according to the ratio of on-chip computation time to off-chip access time.

我们修改现有的DVFS策略，其主要参考目前工作的程式中记忆体存取时间以及处理器计算时间的比例，计算适合的电压，节省电耗。

Cache memory is static RAM with a very fast access time.

高速缓存是指，有着快速存取时间的静态RAM。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。

Ever since our world has been a world, native forests have been indiscriminately exploited by man.

自从我们的世界一直是世界原生森林被任意剥削人。
