集極寬度 的英文怎麼說
中文拼音 [jíjíkuāndù]
集極寬度
英文
collector width-
At the other hand, we can perform the rrpa calculation with the continuum replaced by a set of outgoing single particle resonances, it indicates that the resonances in the continuum play an important role in the description of nuclear dynamical processes, such as collective giant resonances. energies, widths and wave functions of the single particle resonant continuum are determined by solving scattering states of the dirac equation with proper asymptotic conditions for the continuous spectrum in the r ' elativistic mean field theory. the relativistic regular and irregular coulomb wave functions are calculated numerically
在進行相對論無規位相近似計算時將連續譜中所有的正能態用單粒子共振態來代替，並且在計算中採用單粒子共振態的真實寬度，利用這種方法我們計算了核的同位旋標量巨八極共振響應函數，並且和考慮了連續譜中所有正能態貢獻的結果進行比較，計算結果表明，連續譜中只考慮單粒子共振態對核的集體激發的貢獻時，給出的響應函數基本上能夠重現考慮了所有正能態貢獻時的計算結果，這說明了在核的集體激發中，連續譜中主要是單粒子共振態的貢獻。In this modulator, coplanar strips ( cps ) are used as electrodes for they support balance mode propagation of microwave, and this is a desired merit for common optical modulator. due to the miniaturized dimensions, the metallization thickness is in the order of skin depth and the conductor losses are not negligible
雖然由於金屬的趨膚效應，電場將集中在金屬表面，但在40g以上的頻率條件下，金屬的厚度和趨膚深度在一個量級，而且此時調制器帶寬受到限制的最大根源來源於金屬電極的微波損耗。In the first part of this paper, the theory of laser range and dds technology was introduced, the factors of influencing range precision were also analysed. at the same time, put forward in the paper, with using the fpga embedded technology, the wideband and high resolution sin modulating signals can be generated easily, then analysed the noise of the dds ; in the second part, the theory of phase measurement based on fft was analysed. in the phase range system, by using the fft operation, the resolution and sensibility of phase measurement can be enhanced ; then some circuits were designed and come true, also simulated and validated ; in last part, the improvement of the phase range system was brought forward, summarized and expected
論文首先闡述了激光測距和調制信號源的基本原理，分析了影響測距精度的因素，指出應用dds技術可以實現寬帶、高精度的調制信號輸出，說明了引起dds輸出信號雜散的原因和解決的辦法;同時分析了應用fft運算實現信號相位提取的基本原理及設計方法，採用這種檢相技術，可以極大地提高測相精度與靈敏度;然後提出了基於fpga嵌入式系統的相位式激光測距機的整體設計，並就各部分進行了詳細的分析與設計;接著介紹了激光測距系統的外圍電路和基於quartusii集成軟體平臺的部分硬體電路的設計，並對其中的設計進行了模擬和驗證;最後總結提出了對系統今後的進一步改進和完善的思路。Meanwhile, the relatioship between al ' s width of emitter and collector current, which called " extended electrode enhancing current ", has been presented
同時，也給出了大面積鋪鋁的橫向pnp管中發射極電極鋁條寬度與集電極電流的關系，稱之為「電極擴展增強電流法」 。Ultra - high thermal sensitivity, extremely wide dynamic range, and revolutionary longwave imaging performance make the sc 3000 the most advanced solution for ir temperature measurement and
極高的熱靈敏度，超寬的動態范圍，革新化的長波圖象性能以及高速的數據採集能力使得Underwater acoustic data acquisition equipment is necessary for underwater acoustic experimentation. since the situation underwater is very complicated, we must adopt the data acquisition equipment which is adaptive to the abominable field underwater. all of these make us to make the data acquisition equipment to has a wide dynamic range and have the utility to acquire the signals which have large amplitude range
水聲數據採集裝置對於水聲試驗來說是不可缺少的，由於水底的自然環境極其復雜，這就要求我們所採用的數據採集器能夠適應水下惡劣的自然環境，因此所採用的數據採集器應具有較大的動態范圍，所採集信號的幅度范圍要盡可能的寬。分享友人
