并行存取

And we have given Hadamard matrix in detail in block design, coding and the specific application in communication., Hadamard code as a nonlinear combinatorial code has catered to the need of development of computer technology, stock systematic data and high speed for realizing and reliable access, request the error control code has not only little redundancy, but also can parallel encoding and decoding with high speed.

Hadamard码作为一种非线性组合码，迎合了计算机技术的发展对实现存储系统数据高速且可靠地存取，要求所采用的差错控制码不但冗余度小，还应当能高速并行编码和译码的需要。

By the use of parallel transmitting of multichannels, its throughput is increased, the end-end delay of packet is decreased. Such a system can provide a high-performance LAN/MAN that can interwork with standard systems.

在多信道光纤环型网络结构中采用不同一般环网的存取访问介质控制机构，而采用并行运行机构，可大大地提高网络的吞吐量，减少分组端——端平均延时，可广泛用于城域网和LAN互连网络的主干网。

The experiment indicated that this framework would enhance the efficiency of data access and the parallel processing ability.

实验说明，这种模型可以提高数据存取的效率和并行处理能力。

A memory system having a main memory which is coupled to a plurality of parallel virtual access channels.

一种存储器系统，具有与多个并行虚拟存取通道连接的一主存储器。

To realize frame precision when broadcast, an algorithm called MPPDIO (multi-thread parallel pre-fetch Direct IO) is proposed after the characters of the broadcasting part in uncompressed digital broadcasting system are analyzed.

在分析了无压缩数字播放系统的播出工作特性的基础上，提出了一种多线程并行直接I/O存取算法，并建立了计算共享缓冲区大小的模型。

If a "reasonable" notion of database consistency is to be supported (I.c. the database system is to enforce it automatically), there are bound to be" conflict" situations where one transaction comes into an access conflict against some other transaction. If await is to be avoided,some means of a negotiated settlement of the conflict must be provided, thereby dragging the users into the details of concurrency control.The single-database model is more appropriate-ate than the multiple-database model in an environment where it is difficult to determine in advance logical partitions of the database that correspond to work to be performed, and the users closely cooperate.

如果一个数据库一致的合理观念要得到支持（即数据库系统要自动实行这个观念）、一定会有矛盾的情形产生、在这种情形中一个业务与其它业务产生存取矛盾如果要避免等待，就必须提供某种协商解决矛盾的方法，从而迫使用户详细了解并行控制单一数据库模式在某一种环境中比多个数据库模式更恰当，在这个环境中，要事先确定与要执行的工作相适应的数据库的逻辑分割是很难的，同时用户们又紧密地合作在一起。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
