Endocytosis the bulk transport of materials into cells across the plasma membrane by processes not involving diffusion or active transport
內吞作用：大量物質穿過細胞膜逐步地轉運進細胞而並不涉及擴散或主動運輸，被稱為胞飲作用（細胞吸收）或胞噬作用（細胞吞食） 。 -
On the basis of the safety system engineering theory. applying the dow fire & explosion index and the normal stability gauss mathematical diffusion model etc., combining with the practice of mouping port, the hazards during the handling and storage of liquid chemicals in bulk have been analyzed and the risks of fire explosion and leakage ( including water pollution and water pollution ) have been assessed. taking into account of insufficient consideration of the human factor in the dow fire & explosion index, the soft compensation coefficient has been raised
本文以安全系統工程為理論基礎，運用道氏火災爆炸指數法、平均運動方程組以及常穩態高斯數學擴散模型，結合牟平港散化運輸、裝卸的實際，對牟平港散化儲運的火災爆炸危險性和毒物泄漏危險性（包括水污染性和大氣污染性）進行了定性和定量的分析評價。在評價程序上，針對道氏火災爆炸指數法中對人為因素和管理水平等考慮不足的問題，提出了軟補償系數的概念，找出了散化碼頭日常監督管理工作的重點。 -
There are distinct changes about shifts or intensity in bulk plasmon, surface plasmon, and interband electron transitions losses as a result of oxidation of specimens, and adsorption and oxidation processes can be studied through these changes. at room temperature, the formation of oxide layers on uranium and uranium - niobium alloys were found to occur rapidly upon exposure to oxygen, and the resultant oxide in each case was near - stoichiometric uo2. due to formation of niobium oxide in uranium - niobium alloys, the diffusion of o ~ ( - ) ( o ~ ( 2 - ) ) and u ~ ( 4 + ) in the interface region was prevented, and the corrosion resistance of uranium - niobium alloys to oxygen is greatly enhanced by alloying with niobium
研究結果表明：清潔表面鈮和鈾的體等離子體振蕩所造成的電子能量損失的實驗值與理論計算值較為符合；隨著氧化程度的加劇，表面等離子體（ sp ） 、體等離子體（ bp ）以及價帶電子躍遷所造成電子能量損失的譜峰發生了明顯的連續偏移或強度的變化，這些變化可以用來分析鈾及鈾鈮合金的初始氧化過程；室溫下，鈾及鈾鈮合金很容易與氧作用，最終結果，鈾僅氧化為二氧化鈾，另外，在鈾鈮合金氧化過程中，因為有鈮的氧化物存在，不利於氧和鈾在界面擴散，增強了鈾鈮合金抗氧化性能； eels能獲得樣品表面的信息比aes更為表面，更為靈敏，但由於eels的譜線過于集中，主要在幾十ev以內，也有不容易區別和解譜的不足。 -
Life time of mn2 + in nano - zns was measured and was found to be close to that of the bulk materials. therefore the quenching centers quench the exciton but not the mn2 + ion self. 2. the increasing curves are different in film and ethanol colloids because there is diffusion process of quenching centers in colloids
對薄膜樣品的熒光增強曲線的擬合表明，顆粒表面猝滅中心數目隨輻照時間的衰減函數是非e指數形式;同時考慮溶液中猝滅中心通過向顆粒表面的擴散而逐漸耗盡，很好地解釋了溶膠的增強曲線與固體薄膜的增強曲線的不同。 -
In the new structure, a n + buffer layer is introduced into the bulk silicon substrate with a triple - diffusion process. the new structure has two features : one is the feature of npt - igbt : the thin and lightly - doped p + layer and the high lifetimes of the carriers ; the other is the feature of pt - igbt : n7n + structure which can make the n " region very thin
新結構用三重擴散的方法在n ~ -單晶片上引入了n ~ +緩沖層，仍然保留了npt - igbt中薄而輕摻雜p層和高載流子壽命的本質優點，同時又具有pt - igbt中n ~ - （ n ~ + ）雙層復合的薄耐壓層（即薄基區）的優點。 -
Standard test method for determining the apparent chloride diffusion coefficient of cementitious mixtures by bulk diffusion
用粒狀料擴散法測定水泥混合物表面氯化物擴散系數的標準試驗方法 -
At the same temperature ( 25 ), soil bulk density ( 1. 3g / cm3 ) and concentration of applied ions ( 0. 014g / cm ), the value of chlorine diffusion coefficient ( dei ) increased linearly with water content, and that of potassium ( dk ) increased exponentially or power - lawly
25c 、非飽和條件下，四種土壤o一、義的擴散系數均隨含水量的增加而增大，前者隨含水量呈線性增加，後者呈指數函數增加或冪函數增加。
