【正文】 m at developing and utilizing the interface to 3D models, which makes the platform capable of loading 3D model files of different types, such as 3D terrain, 3D vegetation, and other surface features, and finally at building a 3D scene for laser radar trial. Simulation environment modeling of the system finishes the mathematical modeling of the environment in accordance with onsite trial, like the laser pulse model, atmospheric transport model, target interaction model, receiver model, etc. The pulse beams transmit in the environment, and eventually form a fullwaveform with a certain signaltonoise ratio (SNR). On the other hand, the fullwaveform acquired from the onsite trial will be collected by the data acquisition system and then uploaded into the upper monitor on the puter side. The fullwaveform data processing module is to plete the processing for a digital fullwaveform (simulated or onsite), and then to depose the intensity and depth data. Further, the deposed information is utilized to build the 3D image of the target.六．針對(duì)三1中的一篇結(jié)果文獻(xiàn)查找其引用和被引用情況，并判斷其參考文獻(xiàn)的出版類型。：先確定檢索內(nèi)容,分析出關(guān)鍵詞及寫(xiě)出檢索式,經(jīng)過(guò)初步檢索、調(diào)整檢索式后，在CNKI中檢索出相關(guān)內(nèi)容。；每篇的出版類型依次分別是：引用文獻(xiàn)5篇，分別為：1）——圖書(shū)2）——圖書(shū)3）LABVIEW User Manual. National Instruments ——學(xué)術(shù)論文4）GB/T 184592001——標(biāo)準(zhǔn)文獻(xiàn)5）Using External Code in LABVIEW. National Instruments Corporation..2000——學(xué)術(shù)論文。如有被引，請(qǐng)列舉一條引證文獻(xiàn)題錄信息：被引用6次：[1] 李文舉. 基于PCI9054的主動(dòng)DMA傳輸?shù)脑O(shè)計(jì)與實(shí)現(xiàn)[J]. 科技視界. 2014(32)七．檢索課心得。有則多無(wú)則少。本次檢索可感覺(jué)得到了很大幫助，對(duì)中文檢索工具和外文檢索工具都有了一定的認(rèn)識(shí)，并且意識(shí)到圖書(shū)館有很多資源被我們忽略了，平時(shí)沒(méi)有掌握與不清楚的類別再課堂上都有了清楚地認(rèn)識(shí)。這些對(duì)我以后的學(xué)習(xí)有了很大幫助。此外，特別是上機(jī)課的實(shí)踐與利用加深了我對(duì)這門(mén)課的認(rèn)識(shí)。更加意識(shí)到在這個(gè)信息化的時(shí)代。學(xué)會(huì)利用各種資源是很重要的。信息檢索這門(mén)課程很有用，可是要學(xué)好也不是很容易，我們必須多練習(xí)、多搜索，經(jīng)常去查詢、去摸索，并且要仔細(xì)的靜下心來(lái)學(xué)習(xí)，只有真正熟悉了各種數(shù)據(jù)庫(kù)的檢索方法，掌握正確的檢索方法，才能夠快速而準(zhǔn)確的找到自己真正所需要的文獻(xiàn)資料。通過(guò)這段時(shí)間的學(xué)習(xí)，我要感謝老師的耐心教學(xué)，要感謝同學(xué)們?cè)谖也粫?huì)的時(shí)候的熱心幫助，使我們學(xué)到許多有用的東西?？偠灾?，學(xué)習(xí)了信息檢索與利用后，我們對(duì)自己要掌握的知識(shí)來(lái)源都有了了解，這門(mén)課使我受益匪淺。
