frequency difference造句
例句與造句
- To validate the performance of the system , a series of experiments are made on a 200mw unit simulator of max1000 dcs . the results of these experiments indicate : by following certain physical principles , for each real component of the control system , the mathematical model which is constructed to reveal its characteristics reflects exactly the work and message transfer process ; by considering the load demand to the unit and the electricity net ' s frequency difference , also combing with the real capacity that the unit can stand , the ccs and deh models , which are contrived by using simulation blocks , can exactly harmonize the control of the turbine and the boiler and can also control the load .
為驗(yàn)證模型的性能，本文在基于max1000dcs系統(tǒng)的200mw機(jī)組仿真機(jī)上進(jìn)行對(duì)建立的控制系統(tǒng)模型進(jìn)行了一系列仿真試驗(yàn)，試驗(yàn)結(jié)果表明對(duì)控制系統(tǒng)的每一實(shí)際組件按照一定的物理規(guī)律所建立的反映其功能特性的數(shù)學(xué)模型，正確地反映了其工作過(guò)程及信息傳遞過(guò)程；利用仿真模塊開發(fā)的協(xié)調(diào)控制系統(tǒng)及功頻電液控制系統(tǒng)模型能夠根據(jù)對(duì)機(jī)組的各種負(fù)荷要求和電網(wǎng)的頻率偏差，結(jié)合機(jī)組所能承擔(dān)負(fù)荷的實(shí)際能力，正確地協(xié)調(diào)對(duì)汽輪機(jī)和鍋爐的控制，并對(duì)負(fù)荷加以控制。 - Abstract : we have studied the polarization beats spectroscopy with phase - conjugation geometry in a cascade three - level system . it was found that the accuracy for the energy - level difference measurement is determined by the homogeneous linewidths of the optical transitions . under the condition for the occurrence of beating , the frequency difference of the beat between two independent light sources could exceed the laser linewidth . the measurement accuracy for laser absolute frequency could reach the same order of magnitude as the laser linewidth
文摘:研究了級(jí)聯(lián)三能級(jí)系統(tǒng)中的相位共軛極化拍頻光譜術(shù).發(fā)現(xiàn)其對(duì)能級(jí)差的測(cè)量精度決定于光學(xué)躍遷的均勻增寬.在符合拍頻條件時(shí)，兩獨(dú)立光源拍頻的頻差可以超出激光線寬，激光絕對(duì)頻率的測(cè)量精度可達(dá)到與激光線寬同一量級(jí) - T he former is featured by frequent appearance of llj and llsw without kernel , two o f which with large monthly distribution differences , contrary daily variety regulations and large environmental differences , while the latter is characterized by llj with lower monthly frequency differences and ambiguous daily changes
東北地區(qū)的低層大風(fēng)以低空急流現(xiàn)象為主，月際頻數(shù)差異相對(duì)較小，日變化也不明顯。華南大風(fēng)區(qū)內(nèi)，低空急流和無(wú)核低層大風(fēng)現(xiàn)象出現(xiàn)次數(shù)都很多，但兩者的月際分布差異很大，日變化規(guī)律相反，生存環(huán)境差異也很大。 - It's difficult to find frequency difference in a sentence. 用frequency difference造句挺難的
