粗分散體
英文
coarse dispersion-
Beryllium powders with the same particle size and various contents of beo were prepared by pre - sintering - acid washing processes initiatively and the influence of beo alone on o mys of beryllium was observed and some new results have been obtained - compared with the content of beo, the distribution of beo in beryllium has more critical influence on mys ; finely dispersed beo along the grain boundaries and in the matrix results in the dispersion strengthening of beryllium matrix and thereby the higher mys value ; on the contrary, the coarser beo particles clustering on the grain boundaries results in negative influence on o mys
開創性地用預燒結? ?酸洗工藝制備了相同粒度、不同beo含量的鈹粉，從而開展了beo含量單獨對鈹材_ （ mys ）影響的研究，得出一些新的結果：與beo含量相比， beo在鈹中的分佈狀態對_ （ mys ）的影響更大。沿晶界、晶內彌散分佈的較細小beo對基體鈹有彌散強化作用，使_ （ mys ）即較高；如果beo較粗大地成簇狀聚集在晶界，反而對_ （ mys ）有不良的影響。The ultrastructure of the hepatocyte in bufo bufo gargarizans cantor between pro - hibernation and initial post - hi be rnation was studied in this paper. the results show that : 1. the hepatocytes in pro - hibernation period have very plenty of glycogen granules, but nearly not glycog en granules in post - hibernation period ; 2. the hepatocytes in pro - hibernation peri od have very developed rough endoplasmic reticulum, but a few scattered dilatant rough endoplasmic reticula in post - hibernation period ; 3. the quantity of mitocho ndria, and the structure of nuclei and bile canaliculi in pro - hibernation period have not obvious difference from that in post - hibernation period ; 4. two types o f hepatocytes in pro - hibernation were found. the significance of the results men tioned above is also discussed

前人都是採用樣方方法對格氏栲種群數量的空間格局進行測定，而格局分佈有可能受樣方大小的影響，且分析過程中沒有涉及聚塊間密度差的問題，因而無法掌握種群的聚塊大小差別及聚塊內個體間的離散程度.本研究採用無樣方距離法，測定不同生境的格氏栲種群空間格局，分析格氏栲種群格局的強度和紋理.強度以聚塊和間隙的密度差來定義，紋理則是體現聚塊內個體間的離散程度與諸聚塊間的分離程度.測定結果表明，格氏栲種群格局強度從高到低排列次序為：木姜子蚊母樹冬青茜草樹格氏栲米櫧虎皮楠木荷；格局紋理從粗到細的順序是：木荷=木姜子茜草樹格氏栲=冬青米櫧蚊母樹虎皮楠.這一測定結果與作者採用聚集度指標測定相同樣地格氏栲種群空間格局的結果基本相符.因此，格氏栲空間格局類型及分佈與格氏栲生物學特性及生境的關系密切For parameter a, there is a close relationship exist between a ( 9, sr ) in two different radar incident angle that can be expressed as : with considering the effects of soil texture, we get the final expression of the inversion model : where mv ( t1 ), mv ( t2 ) is volumetric soil moisture content in two different temp, c, d is soil type related parameters, and v ( t1 ), s ( t2 ) is coresponding bare soil radar backscattering coefficients. inversion results show that for the c band hh polarized radarsat scansar data with a range of incidence angle from 20 to 40, the soil moisture change value can be derived with an acceptable accuracy using the above model. the temporal and spatial soil moisture change patterns are associated with rainfall and vegetation cover, as well as the soil hydraulic characteristics

目前我國航空運輸業缺乏明顯的國際競爭優勢，尚不具備與發達國家航空運輸業競爭的實力，其具體表現是產業規模小、市場結構分散、管理粗放、資產負債率過高、經濟效益差、營銷能力弱、市場佔有率低等。In 6. 635, topics covered include : special relativity, electrodynamics of moving media, waves in dispersive media, microstrip integrated circuits, quantum optics, remote sensing, radiative transfer theory, scattering by rough surfaces, effective permittivities, random media, green ' s functions for planarly layered media, integral equations in electromagnetics, method of moments, time domain method of moments, em waves in periodic structures : photonic crystals and negative refraction

結果發現：二氧化硅膠體顆粒均勻分佈於脲醛聚合物網路中，煅燒去除有機模板后微球表面變粗糙，而粒徑沒有明顯變化； ph值較小時，復合微球中聚合物含量較大，而ph值較大時，得到復合微球結構鬆散，因此熱處理后的二氧化硅微球孔容及平均孔徑都較大，而在ph = 0 . 8時，得到最小值；武漢理工大學碩士學位論文隨著熱處理溫度的變化，小於160時，空分佈較窄，而比表面積較小，在350時，由於有機模板的去除，微球孔結構發生突變，比表面積明顯增大，而孔徑分佈變寬，溫度繼續升高時，二氧化硅網路發生收縮，平均孔徑變小而比表面積由於有機炭化物的完全去除沒有太大變化;微球中的微孔在熱處理過程中處于平衡狀態，分佈沒有太大變化。This feature reflects the physical phenomenon of breaking of waves and development of shock waves. in the fields of fulid dynamics, ( 0. 2. 1 ) is an approximation of small visvosity phenomenon. if viscosity ( or the diffusion term, two derivatives ) are added to ( 0. 2. 1 ), it can be researched in the classical way which say that the solutions become very smooth immediately even for coarse inital data because of the diffusion of viscosity. a natural idea ( method of regularity ) is obtained as follows : solutions of the viscous convection - diffusion pr oblem approachs to the solutions of ( 0. 2. 1 ) when the viscosity goes to zeros. another method is numerical method such as difference methods, finite element method, spectrum method or finite volume method etc. numerical solutions which is constructed from the numerical scheme approximate to the solutions of the hyperbolic con - ervation laws ( 0. 2. 1 ) as the discretation parameter goes to zero. the aim of these two methods is to construct approximate solutions and then to conside the stability of approximate so - lutions ( i, e. the upper bound of approximate solutions in the suitable norms, especally for that independent of the approximate parameters ). using the compactness framework ( such as bv compactness, l1 compactness and compensated compactness etc ) and the fact that the truncation is small, the approximate function consquence approch to a function which is exactly the solutions of ( 0. 2. 1 ) in some sense of definiton
當考慮粘性后，即在數學上反映為（ 0 . 1 . 1 ）中多了擴散項（二階導數項） ，即使很粗糙的初始數據，解在瞬間內變的很光滑，這由於流體的粘性擴散引起，這種對流-擴散問題可用古典的微分方程來研究。自然的想法就是當粘性趨于零時，帶粘性的對流-擴散問題的解在某意義下趨于無粘性問題（ 0 . 1 . 1 ）的解，這就是正則化方法。另一辦法從離散（數值）角度上研究僅有對流項的守恆律（ 0 . 1 . 1 ） ，如構造它的差分格式，甚至更一般的有限體積格式，有限元及譜方法等，從這些格式構造近似解（常表現為分片多項式）來逼近原守恆律的解。Then, using the large - scale coarse grained soil test system, the relative density and direct shear characteristics of sand - gravel mixtures in different size distribution were tested. and the soc affecting mechanism derived from non - uniform granular material was discussed. the phenomenon can be observed that, along with the increase of non - uniform degree, the accumulate structure will become more complex, and the sliding resistance among sands will grow accordingly
