中文拼音 [jiānbiànkuòsǎn]
漸變擴散
英文
ramscatter-
The annihilation of the octahedron voids at the tips of fpds was divided two processes : ( 1 ) the oxide on the void was removed by the out - diffusion of oi in the shallow region, especially the oi aroud the void and by the entry of the interstitial si atomics. ( 2 ) the void without oxide shrinked by emitting vacances and the migration of silicon atoms from edge to the bottom of void
Fpds端部八面體空洞的消失分為兩個階段： （一）覆蓋在空洞各個內壁上的氧化膜由於高溫下矽片表面區域的間隙氧原子，尤其是空洞型缺陷周圍的間隙氧原子的外擴散及自間隙硅原子的進入，而逐漸變薄直至最終消失。 （二）無氧化膜的空洞，在高溫下發出一個個空位，同時八面體空洞周圍的自間隙硅原子不斷的從空洞的邊緣遷移至空洞的底部，使空洞逐漸變淺直至最後消失。But neither can two great and powerful groups of nations take comfort from our present course both sides overburdened by the cost of modern weapons, both rightly alarmed by the steady spread of the deadly atom, yet both racing to alter that uncertain balance of terror that stays the hand of mankind ' s final war
然而，這兩個強大的國家集團都不能對現狀高忱無憂雙方皆對現代化武器的開支感到不勝負擔，都對致命的原子力量的逐漸擴散理所當然地感到驚恐，但雙方都力圖改變那種遏制任何一方發動人類最後決戰的不穩定的恐怖均勢。With the expand of urban scope, great change have taken place in railroad hinge, many internuncial lines and lateral lines had been surrounded. former status and function had been losed, capacity of transportation is surplus
同時，隨著城市規模的擴張，我國大城市鐵路樞紐也逐漸發生了很大變化，鐵路樞紐內的許多聯絡線、支線逐漸被城市包圍，逐漸失去了原來的地位和作用，運能虛糜，設備、設施閑散。In this thesis we study the existence of periodic solutions and the asymptotic behavior of general time - dependent solutions for periodic reaction - diffusion equations with nonlocal boundary value conditions, the existence of periodic solutions or periodic quasisolutions and the asymptotic behavior of general time - dependent solutions for periodic reaction - diffusion systems with nonlocal boundary value conditions. the whole thesis is made up of three chapters
本文研究時間變量是周期的反應擴散方程在非局部邊值條件下周期解的存在性及其一般時變解的漸近性態；研究時間變量是周期的反應擴散方程組在非局部邊值條件下周期解或周期擬解的存在性及其一般時變解的漸近性態City commercial bank only to be able to sit looked the good opportunity runs away due to above reason and at the same time the region economic integration also loses city commercial bank ' s powerful support, its step will be able not but to slow down, specially started along with state - owned commercial banks to adjust their management mentality in the recent years, changed from scale to benefit, consolidated one batch of small cities branch offices, contracted to big or media - sized cities, causes an enormous change for the finance structure of county and the countryside and extremely influenced county and countryside ’ s economy development
這對區域經濟「極化」與發展極「擴散」的功能都受到制約。在如火如荼的區域經濟一體化的浪潮中，沒有越出中心城市的城市商業銀行只能坐看良機遁去，而同時區域經濟一體化也失去了城市商業銀行的有力支持，其步伐將不得不放慢，特別是近年來國有商業銀行開始調整其經營思路，由重規模逐漸轉向重效益，撤併了一批小城鎮的分支機構，向大中城市收縮，使縣域和農村金融結構發生極大變化，對縣域和農村經濟發展產生非常深遠的影響。In the study, what ' s more, some particular experiment phenomenon are explained by means of theories, such as water move, the change of water and ice. in the test, the preliminary propagation of the hard rock containing a small mount of aperture is dominant during the test, inner damage of soft rock containing a large mount of apertures is largely propagating with the time increasement of circle, because the circle time is limited, the damage propagation can not be observed during enough times
試驗發現，對于強度較大，顆粒孔隙閉合程度較高時最初的幾次凍融循環對損傷的擴展起著主導作用，而後逐漸趨于恆值;而對于強度較低，孔隙貫通程度較高，離散性較大的軟砂巖，隨著凍融循環次數的增加，損傷變量增大，由於本次試驗凍融次數有限，未能觀察到凍融循環次數較高時的損傷變量變化情況。Summaries the research status, particularity and cfd method of the dynamic simulation, and points out that the cfd simulation of contaminant distribution in the crucial medical rooms should be reoriented from static method to dynamic method
對人體動態模擬的研究現狀和特殊性及其cfd模擬方法進行了介紹，提出對醫院關鍵科室內污染物擴散的模擬應逐漸從穩態模擬向動態模擬轉變。Numerical results are obtained for velocity, temperature and concentration profiles, variations of both nusselt and sherwood numbers under different buoyancy ratio and inclination angles of = 15 - 90. at a given inclination angle, heat and mass transfer rates decrease with heat and mass buoyancies and the buoyancy ratio b decrease from high positive values, and then increase again with the buoyancy radio b further decreasing after the velocity and transfer rates reaching a minimum
研究結果表明：傾斜角度一定，當熱浮力與物質擴散浮力共存且二浮力之比b從較高正值變化到較高負值時，流體速度和熱質傳遞速度從高逐漸變低並出現最小值，此後隨著向下浮力的增大，流體向下流動且隨| b |的增大而加速，熱質傳遞速率隨| b |的增大而重新增大。A system of retarted functional differential equations as a predator - prey model with stage structure and dispersion is discussed. conditions for global stability of the system are given
摘要討論了一類帶有擴散和具有階段結構與時滯的兩種群捕食系統，分析了該系統的非負不變性、邊界平衡點性質及全局漸近穩定性。Algorithms of curvature estimation and data simplification of scattered point cloud data are studied. local surface curvature properties on scattered - point data are estimated using a parametric quadric surface approximation, and the key step is local base surface parameteration method which resolves parameteration of scattered - point data. an algorithm is presented for simplifying the scattered point cloud data based on curvature restriction
實例表明，本文演算法的簡化結果既較好地保留了形狀特徵，同時使點的分佈以點雲密集的強制保留區為中心，在向附近擴散的過程中逐漸變稀，避免簡化后點雲的局部過密或局部過稀的情況。分享友人
