ensemble average meaning in English
集合平均
集平均值
系综平均值
总体均值
总体平均
Examples
- Averages will usually be interpreted as ensemble averages , taken over a large number of independent experiments or observations
“平均”通常应理解为“总体平均” ，也就是说，是指对大量独立实验或观测结果进行平均。 - A method of quantitative precipitation forecasts for short - range ensemble forecast is presented aiming at inability of ensemble average method to extreme weather event
摘要针对短期集合预报中集合平均等方法对极端天气事件预报能力低下的缺陷，提出一种定量降水预报集合方法，简称两步法。 - Abstract : the hot wire anemometer and the ensemble average method are used to measure and study the dispersion turbulent transient feature in a closed cylindrical explosion bomb . the comparison of the dispersion turbulent parameters from different shapes of closed explosion bombs is presented . the relation between errors and numbers in dispersion turbulent measurement with the ensemble average metod is discussed
文摘:采用热线风速仪和系综平均法测定和研究了封闭圆柱形粉尘爆炸罐内扬尘湍流的瞬态特性，并与球形爆炸容器内已测定的扬尘湍流瞬态特性进行了比较，对系综平均法用于扬尘湍流的测量误差与测量次数的关系进行了探讨。 - Ensemble averaging ( ea ) is a conventional method for improving the snr of the recorded vep . depending on the snr of the recorded signal , ea requires 100 - 2000 trials to estimate an ep . targets of others methods are concentrated on decreasing the number of repetitions required and speeding up ep estimation
但是平均方法忽略了每次试验之间vep的变异，而且反复刺激会引起神经系统疲劳，危重病人难以承受，也将直接影响到诱发响应的波形，因此对vep进行单次或少次提取并跟踪每次试验中vep的变化成为人们关注的研究目标。 - The communication system ' s performance is briefly analyzed by channel capacity , which is a function of bit error rate ( ber ) . the decision rule is based on the most likelihood method . for reproducing the original binary signals more correctly , time scale transformation method and the approach of ensemble average probability of error bits are introduced
通过理论分析和仿真实验，本文研究了这个非线性数字通信系统性能，给出了误码率和信道容量公式，提出了系统参数调节方法，采用最大似然法设计了适合这个系统输出的判决规则。
