以擴展分維作為理論基礎，從變維分析的角度出發，研究地圖目標的自相似程度隨比例尺變化而衰減的規律，進一步研究地圖目標的尺度指標與分形衰減之間的關系。Their statistical models attempted to correct for potential “ confounding variables ”, such as the fact that an economic downturn and financial uncertainty may increase mortality rates regardless of whether there is a banking crisis
他們的統計模型試圖校正潛在的「混淆性變量」 ，例如，無論是否存在銀行業危機，經濟衰退和金融不確定性都可能導致死亡率上升。According to the characteristic of ieee 1394 with wide bandwidth, common and real - time, the author put forward ieee 13 94 should be applied into real - time digital video transfer in optics - electronics theodolite. before engineering realization, carried out a video image transfer test on three types of digital video tape recorders and camera with ieee 1394 interface. we found that digital videos without compression transfered under ieee 1394 standard ( transfer from 4. 5m to 100m ), compared with analog videos, have no geometric distortion, and have better luminance, contrast, definition
作為工程實現前的實驗研究，對三類具有ieee1394介面的數字錄像機和攝像機進行了視頻圖像傳輸實驗，發現無壓縮格式的按ieee1394標準傳輸的數字視頻圖像（傳輸距離從4 . 5米到100米之間） ，較原始模擬視頻圖像在幾何位置信息上沒有衰變，而在亮度、對比度、邊緣清晰度這些方面有明顯的優勢；但是按dvcam壓縮格式（常見于sony公司的系列產品，是5 ： 1的dct幀內壓縮）壓縮的數字視頻圖像，較原始模擬參照圖像有明顯的幾何畸變。It is based on the principle : under a number of angles, the x - ray attenuation in a cross section of a human body is measured by detector resulting in a set of profiles. this set of profiles is called the radon transform of the object in mathematics. the problem now is to reconstruct a two - dimensional image via inverting its radon transform
它所基於的成像原理是：人體的某個剖面在若干個角度上被x射線束照射，照射后x射線的衰減量被檢測器記錄下來，形成投影集合，數學上將這個投影集合描述為該剖面的radon變換，通過反演radon變換就能夠重建剖面的二維圖像。Computerized tomography ( ct ) is a typical non - invasive examination techniques in medicine, which can depict anatomical structures without damaging the human body. lt is based on the principle : under a number of angles, the x - ray attenuation in a cross section of a human body is measured by detector resulting in a set of profiles. this set of profiles is called the radon transfoim of the object in mathematics. the problem now is to reconstruct a two - dimensional image via inverting its radon transform

青春是一種氣質:勇猛果敢而不是怯懦退縮，渴望冒險而不貪圖安逸.一個60歲的老人身上常常散發著這種氣息，而20歲的青年身上倒未必可尋.沒有人單單因為年歲增長而衰老，而一旦喪失理想，就會真正變老In this paper, we perform the tree - level and one loop correction to two - higgs - doublet decay h tb in model ii and model iii and give diagrams of the trend of tree - level and correction decay width ratio versus tan
）衰變在模型（ model ）和模型（ model ）中的單圈輻射修正，對這兩個模型進行比較，並給出了樹圖級和單圈修正後的兩種模型下的衰變寬度比隨參數tan變化的規律。From the point of kinematics and dynamics, the author analyses the propagation rules of stress waves in concrete, namely time - space relations, wave amplitude attenuation, dispersion effect and characteristics of transmission of reflected waves and acoustic waves. combining with engineering practices, the author also concluded the main points of low strain detection of integrity of longdiameter underwater cast - in - situ piles, and pointed out that comprehensive and relational utilization of reflected waves method and acoustic wave transmission method can accurately evaluated the integrity of pile shaft and then improve the reliability of detection. 6figs., 3refs
從運動學和動力學角度，分析應力波在混凝土中的傳播規律：時空關系、波幅衰減、頻散作用以及反射波與聲波透射的特點，結合工程實踐，總結大直徑水下灌注樁低應變檢測的工作要點，指出綜合、合理運用反射波法與聲波透射法，可以較準確地評價樁身完整性，提高檢測結果的可靠性.圖6 ，參3分享友人
