查询词典 ber

Then,during a six-hour operation at the Duke University Medical Center in Novem-ber 1998,Wester was given Tim's liver.

可后来，1998年11月，在杜克大学医疗中心做的一次长达6小时的手术中，他换上了蒂姆的肝脏。

But in the case of long-range acoustic communications in shallow water it is disturbed by severe multipaths whid produce increased inter-symbol interference. So the error of frequency estimation for the week signals is bigger and the BER becomes larger.

但是，用于浅海远程水声通信时，由于多径传播的影响，导致严重的码间干扰，使得远程微弱信号的频率估计产生较大偏差，误码率显著增加。

The neighbor-ing two Gd3+ ions are connected by two simple bridged carboxyl groups and a μ2-bridging carboxylgroup. Each G-d3+ ion is simuetaneosly coordinated by two water molecules. So the coordination num-ber of Gd3+ is nine, forming a coordination polyhedron of distorted mono capped square antiprism.

相邻Gd3+离子通过2个简单羧基桥和1个μ2羧基桥联结起来，还有2个水分子配位于每个Gd3+离子，所以Gd3+的配位数为9，形成变形的单帽四方反棱柱体。

These results suggest that the effects of Ber are closely related to the action on the central cholinergic system.

结果提示，Ber可能是通过影响中枢胆碱能系统在海马产生θ节律，减低皮层功率，这可能是其改善和促进学习记忆的神经生物学机制之一。

Three uniform random sequences are built by the linear congruential method, of which two are used to form integer num, ber and decimal fraction parts of the new random sequence respectively and the third to shuffle the new sequence.

采用线性同余法生成3个均匀分布随机序列，其中两个分别组成新的随机序列的整数和小数部分，第3个用来对新序列进行混洗。

For the tracking system, the means that can intellectively assist the fault diagnosis and maintenance is significant. Then we can avoid relying heavily on the experiences of the engineers and can reduce the probability of the event that engineers climb up to the antenna with heavy instruments when the faults turn out. For the data channel, to get the high-qualified remote sensing images, we need to get the quantitative data about how the factors influence the BER of Receiver .The data can help the design of receiver and the evaluation of the performance of a receiver. This thesis mainly contains those two parts.

对于跟踪系统，研究一套能辅助系统故障诊断及维护的智能手段是非常有意义的，这样系统维护时可以避免过多依赖技术人员的维护经验，特别是接收天线发生故障时携带仪器攀爬天线的情况；对于数据通道，面对高质量的遥感图像数据要求，我们需要得到影响接收机误码性能的各主要因素对应的量化数据，这些数据对于接收机的设计及性能评估是非常有帮助的。

We started in Novem ber, but unfortunately we can't join the lesson three times per weeks. We are trying to come at least twice per week but sometimes we miss a week and we know this is not good for the training.

我们是2007年11月份开始学习的，但是因为一些原因，我们不能按照正常规定的每个星期去锻炼三次，但是我们一直在努力每个星期锻炼两次。

Change.W hen voters chose Barack Obam a over John M cCain in Novem ber,they w eren'tjust electing the next president.

变革。选民在11月份选择贝拉克·奥巴马而非约翰·麦凯恩时，他们不仅是在选择下一届总统。

Server agent coded by writer is presented in detail through the SART method,and some creative key technologies are analyzed such as the combination of the software signal、the properties of process and process communication that not only solved the real monitoring problem;the adoption of the UNIX phoney system-PROCFS that not only solved the real monitoring problem;Encoding and decoding to SNMP message on BER-solved the problem on monitor between several operating system.

文章最后给出了笔者负责编写的服务器代理的实现技术，采用SART方法对服务器代理的整体框架和各组成模块进行了详细描述，并对编码过程中的一些创新技术进行了分析，如：将UNIX系统中软件中断信号、UNIX进程的特性和进程间通信有机的结合起来，解决了代理的启动/关闭进程、探测进程状态等实际监控难题；利用UNIX系统的伪文件系统PROCFS进行资源探测，解决了系统中不能用SNMP进行探测的实际监控难题；采用BER编码规范对SNMP报文编码和解码，解决了系统中利用SNMP进行跨平台监控的难题。

Simulations show that a sectored WCDMA system can be of better SINR and BER performance when the systems are of large number of users.

仿真结果表明当系统信道被大量用户占用时，分扇区WCDMA系统仍能够获得较好的信干比和误比特率。

It was just a normal day of school

那只是上学的普通一天

Which is a very good reference in this issue.

这是一个在这个问题上很好的参考。
