硅同位素 的英文怎麼說
中文拼音 [guītóngwèisù]
硅同位素
英文
silicon isotope-
Composed of micro diamonds, aluminum oxide, and silicon carbide, the isotopic distribution of these grains bore the telltale marks of their birth : ancient supernovas and red giant stars, that shone brightly and then flickered out, billions of years ago, before the birth of the solar system
由微金剛石、鋁氧化物、碳化硅組成的這些微粒的同位素分佈透露出它們的誕生：那些數十億年前，在太陽系尚未誕生時，曾經閃耀並最終熄滅的古老超新星和紅巨星。Objective : to investigate the effect of pumpless portosystemic bypass in clinical piggyback liver transplantation. methods : after catheterized inferior mesenteric vein, the silastic catheter ( filled with heparin saline ) was connected with the catheterized tube of internal jugular vein or subclavian vein in four piggyback liver transplantation patients. the channel was opened after the portal vein was occluded. the portal vein blood poured into the superior vena cava through the pumpless channel. the changes of mesenteric congestion, portal vein pressure, blood pressure and pulse were observed. results : during the occlusion of portal vein, the portal vein pressure was increased greatly, the intestine was congested and swelled obviously and the blood pressure and pulse fluctuated gently. after the pumpless bypass opened, intestinal congestion and swell were abated markedly, the portal pressure, blood pressure and pulse gradually returned to normal range. conclusions : pumpless portosystemic bypass shows a great effect on clinical piggyback liver transplantation. it is a feasible and economical method
目的探討背駝式原位肝移植術中採用體外門-體靜脈無泵轉流的臨床效果.方法4例行背駝式原位肝移植患者，腸系膜下靜脈屬支插管經體外硅膠管（充滿肝素鹽水）與頸內靜脈或鎖骨下靜脈插管相接，在阻斷門靜脈后開通腸系膜下靜脈插管，門靜脈血從體外無泵轉流管流入上腔靜脈，觀察轉流前後腸道瘀血、門靜脈壓、血壓、脈搏等變化情況.結果門靜脈阻斷后腸道明顯瘀血、腫脹，門靜脈壓力明顯升高，血壓、脈搏有不同程度的波動，無泵門靜脈轉流開放后，腸道瘀血、腫脹明顯好轉，門靜脈壓力逐漸恢復正常水平，血壓、脈搏恢復正常.結論背駝式原位肝移植術中體外門-體靜脈無泵流具有方便、經濟、實用等優點，具有良好的臨床效果We have interpreted in the same way the production of radioactive elements in boron and magnesium in the first an unstable nitrogen with a half life of 11 minutes is produced, and in the second, unstable isotopes of silicon and aluminum
我們還用同樣的方式解釋了在硼和鎂中製造放射性元素的過程：首先製造一種半排出期為11分鐘的不穩定的氮，然後製造不穩定的硅和鋁同位素。( 3 ) the free - standing porous silicon films with continuous porous structure were prepared on single crystal silicon wafer by the method of anodic oxidation and electrochemical etching - electropolishing, and firstly used as the anode materials for lithium ion secondary batteries. the capacities of lithium ions storage and the process of charge and discharge of this nano - silicon anode materials as well as the influence of the structure of ps on behavior of storing lithium ions were inspected at length. on the other hand, through the process of charge and discharge in cells, the lithium of light metal element could be electrochemically doped into ps at different doping levels
胡勁松河北師死大學碩士學位論文（ 3 ）利用陽極氧化法在單晶硅基底上制備了多孔硅自支撐膜，並首次將這種具有連續多孔結構的硅材料用作了理離子電池的陽極材料，考察了這種納米級硅陽極的儲鉀性能和充放電過程，分析了材料結構對其儲理行為的影響；另一方面，利用這種電池充放電過程在多孔硅中電化學引入了不同點綴程度的輕金屬鉀元素，考察了鉀點綴對多孔硅自身結構，及至性質所帶來的影響，提供了一種通過電化學方法插入埋離子從而連續調整多孔硅發光性質的有效方法。The lattice constants were refined using celref program. when implanted c / fe ions ratio is 0. 5 %, the p lattice is expanded, though c atom is much smaller han si. this is probably due to the solid solution in interstitial state
單胞的間隙位置，形成間隙型固溶體，使晶格膨脹；當摻雜的碳離子含量增加到一定的程度時，趨向于形成置換固溶體，因為碳和硅屬同族元素價態相同，所以碳會置換p 。分享友人
