| 1. | In electronic detectors such as photomultipliers and television tubes, noise manifests itself as random fluctuations in the output current . 对于光电倍增管,电视摄像管之类的电子探测器,噪声则表现为输出电流的随机起伏。 |
| 2. | The alarm aura of financial distress discriminant analysis : a random fluctuation model 财务困境分析中警兆指标的随机游动估计 |
| 3. | Cyclostationarity of vibration signal of rotating machine with random fluctuation of angularspeed 转速随机波动旋转机械振动信号的周期平稳性 |
| 4. | Influence of the sampling method of signal with uniform random fluctuation frequency on spectrum analysis 频率均匀随机波动信号采样方式对谱分析的影响 |
| 5. | The main purpose of this study is to simulation a random fluctuation of wind velocity fitted to specified power spectrum in low frequency range in our wind tunnel 本文研究的目的是在风洞中模拟风速随机波动的阵风,这个基础性工作对于开展风洞中的其它研究有着重要意义。 |
| 6. | To determine whether these variations in seismicity levels are random fluctuations or real physical phenomena , objective testing of unambiguously stated hypotheses is required6 为确定地震活动性中的这些变化是否是随机偶然的波动,还是真实的物理学现象,对不含糊指明的假说有必要进行有目标的试验90 。 ” |
| 7. | When laser diode illuminates the rough surface moving transversally across the light beam , the feedback light forms the random speckle due to the random pattern of the target surface , causing random fluctuations in the laser output , which is called as self - mixing speckle interference 结合自混合和散斑的原理,将散斑现象引入半导体激光器。让半导体激光器的光学反馈来自垂直地照射的粗糙表面,把光强调制成为随机的散斑信号。 |
| 8. | Considering the random fluctuation traction load ( from 0 to max , variable at every minute ) , the life limit of all kinds of machine switches and expensive cost and complex overhaul of svc , this paper aims to develop a set of svc suitable for the present condition of our country . in order to resolve the reactive power returning back problem and realize static adjustable compensation to improve negative sequence 本文针对电气化负荷变化频繁、 svc价格昂贵及检修复杂、机械开关无法担负频繁操作任务的现实,提出通过改造svc结构,把tcr改为tsr ,把tsc实现粗调、 tcr实现细调改为由tsc调节欠补无功、 tsr调节过补无功的技术方案。 |
| 9. | The introduction black - scholes models still assumed , namely the introduction of modern process ( wiener process , also called brownian motion ) to save the stock yield random fluctuations , weak markets and the effectiveness of the use of consistent share of the techniques ( ( markov property ) to describe the stock price change random process , the use of risk - neutral pricing theory through the analysis of the nature of asset price process martingale , established european style to the value of stock options with mathematical models 本文仍然引入black - scholes的模型假定,也即引入维纳过程( wienerprocess , alsocalledbrownianmotion )来刻画股票收益率的随机波动,采用与弱型市场有效性相一致的股价的马尔可夫性( markovproperty )来描述股票价格变化的随机过程,运用风险中性定价理论,通过分析资产价格过程鞅的性质,建立了欧式再装股票期权价值的数学模型。 |
