Bispectrum analysis is emerging as a new powerful technique in signal processing, which can describe nonlinear coupling, restrain Gaussian noise and reserve phase component. 双谱是信号处理中一种新的、功能强的技术,它可以描述系统的非线性耦合,抑制高斯噪声和保留相位信息。
The differential protection sensitivity of different principles is determined by the reservation of sequence component in differential current. The sensitivity of winding differential protection and phase current minus zero-sequence current differential protection are higher because they fully reserve the sequence component of fault current. 绕组差动与相电流减零序差动(中性点零流)的灵敏度最高,它们完全保留了内部故障电流中的各序分量;
The construction of oil reserve base is an important component of national energy security and economic development, and large-sized non-anchored storage tank, as one of the advanced equipments of oil reserve base, its safety research has attracted more attention. 石油储备库建设是国家能源保障和经济发展的重要组成部分,大型非锚固储罐是石油储备库的先进设备之一,其安全方面研究倍受关注。
According to oil and gas reserve layer character, mineral component of Zhongyuan Oilfield, latency damage factors to deep oil and gas layer were analyzed. 针对东濮凹陷天然气藏储层特征,研究了保护天然气储层的钻井完井液体系。
Those deposits are called reserve balances and are the key component along with currency of base money or central bank money which ultimately brings about changes in broader money supply measures. 这些存款叫做准备金余额,与通货一起作为基础货币或中央银行货币的重要组成部分,最终将带来更广泛货币供应衡量指标的变化。
