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 礦山地質平剖面圖自動轉換系統研究與應用
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構。
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生的場看作是偶極層的邊緣旋度源的點分布產生的場;然后給出旋度源的掃描函數,用概率成像方法對旋度源進行成像。
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materials , the paper mainly utilized the qualitative methods combining with some quantitative tools , studied the historical documents and statistical data of world economy and trade since 1431 , some of which is much precious .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上,以歷史的視角結合橫斷面數據,運用定性為主、定性與定量相結合的研究方法,盡可能地查閱了1431年以來的歷史文獻和統計數據(其中有些數據甚為珍貴) ,從中得出了若干具有新意的結論。
Efficient algorithms are proposed to build standard views or section views . and an automatic view placement algorithm is presented in this paper . this paper presents an intelligent dimensioning approach to generate dimensions for 2d drawing automatically for 3d models based on feature extraction 該策略的基本思路為:通過對于三維尺寸冗余和三維尺寸特征的識別,自動生成一個三維尺寸組;然后將這些三維尺寸映射成為二維尺寸并進行布局,由此完成尺寸的自動生成。
