Probe into the survey method of the underworkings ' section view 井下巷道剖面圖測量方法的探討
Research and application of the automatic conversion system of the geological plane and section view drawings of mines 礦山地質(zhì)平剖面圖自動轉(zhuǎn)換系統(tǒng)研究與應(yīng)用
Layered structure has been found ( or could be deduced ) upon the tem observations from both cross section view and plane view specimens 本論文的第一部分,是分別制備平面和截面電鏡樣品,并利用電子顯微鏡研究鈦合金表面生長的羥基磷灰石的結(jié)構(gòu)。
Firstly , sp supposed to be generated by point curl source which is the border of dipole layer rather than the line dipole layer in section view , then , curl source scanning function is given , and image is retrieved by probability tomography approach 首先把剖面上偶極層的線分布產(chǎn)生的場看作是偶極層的邊緣旋度源的點分布產(chǎn)生的場;然后給出旋度源的掃描函數(shù),用概率成像方法對旋度源進(jìn)行成像。
On the basis of abundant materials , the paper mainly utilized the qualitative methods combining with some quantitative tools , studied the historical documents and statistical data of world economy and trade since 1431 , some of which is much precious . then the author got several new conclusions in the historical and cross - section view . the paper is arranged in a logical order as much as possible for better understanding 論文在充分占有資料的基礎(chǔ)上,以歷史的視角結(jié)合橫斷面數(shù)據(jù),運(yùn)用定性為主、定性與定量相結(jié)合的研究方法,盡可能地查閱了1431年以來的歷史文獻(xiàn)和統(tǒng)計數(shù)據(jù)(其中有些數(shù)據(jù)甚為珍貴) ,從中得出了若干具有新意的結(jié)論。
