查询词典 reference level

Later I realized from teacher's comments that I had used too much on-line information and lacked my own ideas; plus I made many errors with my reference. Now I understand that personal perspection and correct reference are the keys to a successful essay, and it was exactly the lack of both in my essay that had led to such an otherwise unexpected low score.

拿到这份EASSY我非常惊讶，后来看到老师对我的评语，才知道是因为在我的EASSY里运用了过多的网上资料却没有很多自己的idear而且references也出现了很多问题，在写eassy的过程中表达自己的观点和清晰的references是最重要的，而我正是犯了这两个严重的错误所以导致我得到一个意想不到的分数。

Chapter 2 discusses the function of optimum array based on the minimum meansquared error principle in CDMA system, the method of produce the reference signal, and proved whether the reference signal is the correspond PN code sequence or respread signal, the result of the array's weight converge can converge the same optimum weight under the condition that the PN sequence in a bit of data is long enough. In this chapter, we finally get the beam pattern and the correlate bit error rate after converge when several CDMA signal arrives in different direction.

本文的主要贡献及创新之处是：首次从理论上探讨了基于最小均方误差准则的最优天线阵在CDMA系统中的多址干扰抑制性能及其参考信号的产生方法，证明了采用有用信号相应的扩频码作为参考信号与采用将解扩信息与扩频码进行重扩频后的信号作为参考信号来调节自适应天线的权值均可使权值收敛于同一最优解。

Thirty-one papers did not describe the selection criteria clearly, 18 did not describe whether all the included patients were verified by using a reference standard of diagnosis, 36 did not describe whether the index test results were interpreted without knowledge of the results of the reference standard, 37 did not report the uninterpretable/intermediate test results, and 34 did not report the withdrawals from the study.

In this paper,a new variable structure robust model reference adaptive control scheme is proposed,which deals with a class of SISO plants under parameter and unmodelled dynamical uncertainties.It is shown that even with the existence of unmodelled dynamics,the output tracking error will converge to zero in finite time, and the SPRcondition for reference model is not required.

摘 要 讨论了含结构不确定SISO系统的变结构模型参考鲁棒自适应控制问题，提出了一种新的变结构控制方法，使得：1系统在同时含参数及结构不确定性时，跟踪误差仍能在有限时间内收敛到零；2无须假设参考模型为SPR函数。
