查询词典 envelope

Moreover, simulation results show that it has a better performance in terms of the probability density functions of the envelope and phase, the level crossing rate, and the average fade duration than the previous methods.

仿真结果表明，改进后的方法生成的复随机过程的幅度、相位的概率密度函数及平均电平通过率、平均衰落持续时间能更好地逼近理论参考值。

The weary lineman replied,"Ma'am, I'll be coming to you in a truck, not an envelope."

已筋疲力尽的电线工回答，"女士，我是坐卡车来的，不是坐信封"。

Results 20 cases of CT examination had made proper diagnoses,the CT imaging finding about the most of peripheral cholangiocarcinoma included:There was the atactic low density tumour in liver,its borderline was unclear,enhanced scan appearances were irregular peripheral enhancement,centripetal enhancement,and delaying enhancement;There was concretion and dilatation of bile buct in or around the focus;The local envelope of liver was lacunose and the local liver was atrophied,There was abroad putrescence and liquescence in the focus.

结果 20例CT做出了正确的诊断，大部分周围型胆管细胞癌的CT表现为肝内不规则低密度肿块边界欠清，增强扫描表现病灶边缘呈不规则环状强化，有向心性强化的趋势，出现延迟强化；病灶内或周围可见结石，病灶内及周围肝内胆管扩张；局部肝包膜回缩、肝叶萎缩，病灶内大片坏死、液化。

The straight line log N=1.5 matches the upper envelope of the lower limits corresponding to a minimum S/N = 200 in a typical solar twin.

图中直线log N=1.5代表最小信噪比为200的类太阳恒星中Li含量对数的上限。

As we known, common Loran - C receiver employs a fixed da- tum - mark in order to avoid interference caused by skywave, as the SNR is often poor at this point due to the amplitude limit of the pulse envelope, so it greatly increases time for tracking the datum - mark.

常规接收机为了防止天波干扰，将基准点设置在一个固定位置上，导致基准点处信噪比受包络限制而较低，从而大大增加了对准基准点的时间。

Upper and lower bounds on peak-to-mean envelope power ratio in OFDM systems are derived in this paper.

本文主要对OFDM系统中的峰值平均包络功率比的上下界进行了推导。

Using EMD method, there is bound to be divergent phenomena at the two ends of the upper and lower envelope signal in the data through the three interpolation algorithm, which is end effect. It will affect the quality of EMD decomposition badly, so that the decomposed IMF has no actual physical meaning.

在EMD方法应用中，通过三次条插值算法给出的上、下包络在数据信号的两端不可避免地会出现发散现象，即端点效应问题，会严重影响EMD分解的质量，使分解出的IMF没有实际的物理意义。
