常見(jiàn)例句雙語(yǔ)例句And the energy of the eastern component is mostly increased with time-variation.東向分量的能量隨時(shí)間的變化以增加為主。Experiments show that the technique is effective for processing unstable signals of time-variation spectra.實(shí)驗(yàn)結(jié)果表明,該法是分析處理具有時(shí)變譜特性的非平穩(wěn)信號(hào)的一種有效方法。The problems summarized as below: it is a nonlinear and time-variation system with uncertainties, and it is more complex. So the high performance of this control system is required.其主要表現(xiàn)在:系統(tǒng)越來(lái)越復(fù)雜、存在非線(xiàn)性、時(shí)變性和不確定性,從而對(duì)控制系統(tǒng)的各種性能要求越來(lái)越高。 返回 time-variation
