At present, people usually use birefrigence and quasi - phase - matching methods to achieve higher effiency in the process of conversion. a significant advantage of quasi - phase - matching method is that the interaction is occurred through the largest element of the x ( 2 ) tensor ; the period of optical superlattice can be designed randomly, and any interaction can be matched without walk - off angle ; they are fitted to be used in frequency conversion of lower power especially. the quasi - phase - matching method has some advantages over birefrigence method, improving the efficiency of frequency conversion ; the range of frequency conversion covers its whole transperant wavelength
由於準相位匹配技術有其獨特的優勢,可以利用非線性光學晶體的最大二階極化張量,如ppln 、 pplt 、 ppktp用的非線性極化張量都是d _ ( 33 ) ,其有效非線性系數高出普通非線性光學介質(如bbo 、 lbo 、 ktp )一個數量級,而且可以人為靈活設計調制周期,通過周期設計其頻率變換范圍可以覆蓋準相位匹配介質的整個透明波段,選擇無走離效應,解決了常規pm難以解決的問題,拓寬了非線性晶體的應用范圍,極大地提高了頻率轉換效率,已成為非線性光學材料和固體激光器的研究熱點之一。The scc has the following advantages : remarkably reducing the noisy pollution and the worker s labor intensity in construction, deducing the rough surface or segregation because of missing - vibration or excessive - vibration in conventional construction, resolving the quality - defect problems resulting from lacking - vibration in the section of complex shapes and densely - packed reinforcement area. at the same time, large of industrial solid waste such as fly ash and blast furnace slag is utilized in the proportioning of scc. it is helpful in comprehensive utilization of resource and environment protection, so the scc belongs to " green concrete ", it is a branch of hpc which will be developed in the future
這種混凝土可以顯著降低混凝土施工中的噪音污染;大幅度減輕工人的勞動強度;減少傳統混凝土施工中因漏振或過振造成的麻面或離析;解決了配筋密集、結構復雜部位因振搗不足而造成的質量缺陷問題;同時,由於自密實混凝土在配製中,大量利用粉煤灰、高爐礦渣等工業固體廢棄物,有利於資源的綜合利用和生態環境的保護;從而被譽為「綠色混凝土」 ,是未來混凝土向高性能發展的方向之一。Abstract : in order to process signal in depth and to extract the fault feature from original signal in machinery diagnosis , the graphical display algorithm that can keep the data length of wavelet transform results the same as that of original signal is used. the fault diagnosis of a bend axial piston pump via b - spline wavelet that has linear phase is provided. the results of study demonstrate that the new method has excellent feature and the weak fault signal can be extracted from the strong vibration background of the pump
文摘:採用具有線性相位的b樣條小波,應用圖形顯示演算法並結合小波變換快速演算法將信號分解到不同的頻帶上,且分解結果和原信號長度保持一致,可對信號進行深層次的處理,克服了傳統的信號處理方法不易提取微弱信息的不足.通過對礦用斜軸式柱塞泵振動信號的分析,分離出了配流副磨損、球鉸松動、缸體及泵軸支撐軸承的故障特徵,為液壓泵的故障診斷提供了依據,並為信噪分離、微弱信號提取及設備的早期故障診斷提供了一條有效途徑This paper gives a detailed account of the waveform, matched - filter, fuzzy function, resolution in speed, resolution in range and the capacity of anti - interference of the chirp signal. it deals with several methods to produce chirp signal and the advantages and disadvantages of these methods. it describes the working principle and performance of dds, analyses the phase errors initiated by the phase truncation and proposes a new scheme to solve the error
