查询词典 preambles

A All descriptions in the Bills of Quantities shall be read in conjunction with the Preambles Clauses hereunder which are relevant to the whole of the Works contained in this Contract.

工程量清单中的所有描述和导言条款是与随后的本合同中所包含的所有工程有关的。

A term used as stated below is shown in italic type or, in preambles, in bold italic type.

依下列所载应用的术语是被以斜体显示，在弁言中则是以粗斜体。

According to the recommended frame structure of IEEE802.16,the independent correlation of multiple preambles and the unique words in data sequence were adopted in the algorithm,and the initial timing offset was estimated.

该算法基于IEEE802.16推荐的帧结构，利用多个前导字的独立互相关特性和数据序列中插入的独特字，对定时误差进行初始估计，并用内插环路进行定时估计误差的跟踪，获得定时同步结果。

This paper deals with frame detection of OFDM signal with multiple-periodic preambles transmitted over frequency-selective channels and with existence of carrier fre-quency offset.

摘要该文研究了具有多周期前导字WLAN OFDM帧信号在多径弥散信道、存在载波频偏条件下的检测。

The Rule also requires that all preambles state that individuals under the age of 18 must have the permission of a parent or guardian to complete the call. The 900 Number Rule has been very instrumental in reducing the level of 900-num- ber abuse.

规则还要求导言声明所有18岁以下的人必须得到家长或监护人的允许才能发起呼叫。900电话号码规则在减少900号码滥用方面非常具有指导性。

Simulations indicated that, in the condition of without any preambles, carrier phase could be acquired fast and tracked steadily, and this scheme still worked well even in low SNR level condition.

软件仿真结果表明，该方法能快速恢复和跟踪载波相位，即使在较低的信噪比情况下，解调系统也能正常工作。

She wondered why anyone would solicit her opinion on international terrorism, but after some vague preambles about "the social fabric", the reporter's purpose became clear:"Well," he said gleefully,"this sure pushes feminism off the map!"

她不知道为什么每个人都要征求她对国际恐怖主义的看法。不过在让人摸不着头绪地谈论了一番&社会结构&之后，这位记者的真正意图开始清楚地显露出来了：&我的意思是，&他高兴地说道：&这肯定会让女权运动毫无立足之地。&

The total throughput of the hub is limited to the speed of a single link, either 10 or 100 Mbit/s, minus the overhead for preambles, inter-frame gaps, headers, trailers, and padding.

集线器的总吞吐量受到单个连接速度的限制( 10或100 Mbit/s )，这还是考虑在前同步码、帧间隔、头部、尾部和打包上花销最少的情况。

A kind of GCL(Generalized chirp-like) sequences are adopted as the preambles of the random access channel, and a cyclic postfix is added. This structure can utilize the perfect periodic correlation properties of GCL sequences effectively to improve the detection performance.

采用具有GCL(General chirp-like)序列作为随机接入信道的前导码，并加上了循环后缀，该结构能够有效利用GCL序列良好的周期相关特性提高检测性能。

Synchronization in Ethernet networks could be done using shorter preambles if there were only twisted pair cables; but since the standard was made for coaxial cables, the preamble needs to be longer because the first transmitted bytes of a frame are damaged on a coaxial cable.

如果以太网中只是用双绞线互联的话，以太网的同步可以使用更短的前导码；但是因为以太网标准是因同轴电缆而定义的，前导码需要更长，因为在同轴电缆上，一个frame中刚开始发送的几个字节是会被破掉的（这里很奇怪，难道同轴电缆在发送有效的信号的时候，刚开始的数据是有损的吗？

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
