硼和鋁對鎂燃點的影響特點。
As is the case with everyday objects such as wineglasses or guitar strings, objects made from lower - mass materials have higher characteristic frequencies than otherwise identical objects made from higher - mass materials
將原有的鎂或
硼以它們的同位素取代，我們可以製造出由不同質量的原子所構成的
硼化鎂。
Mgb2 can be cooled by liquid hydrogen or liquid neon or by fairly cheap, closed - cycle refrigerators that can readily reach below 20 k
硼化鎂可以藉由液態氫、液態氖或是相當便宜的封閉循環式冷凍機，輕易降溫至20k以下。
According to the literature in the world, now the research of lab6 is not mostly concentrated in field emission but hot emission. preparation of lab6 field emitting cold cathode is correlative with it ’ s physical and chemical characteristic. now, there are little literature that can be used for reference
人們已經對六
硼化鑭材料的性能做了大量研究工作，但據目前所見到的國內外文獻所知，對六
硼化鑭陰極的研究多集中在它的熱發射方面，對于以此種材料場發射冷陰極方面的研究較少。
A large number of attempt and painstaking experiment have been done in this paper according to existing project. we also do lots of chemical and electrochemical etching research in material of lab6, and find out three kind of methods to produce the field emitting cold cathode including reactive ion etching ( rie ) with oxygen, wet process etching and electrochemical etching. through produce some field emitting cold cathode single tip including lab6 field emitting cold cathode, molybdenum field emitting cold cathode, tungsten field emitting cold cathode, tungsten rhenium field emitting cold cathode, molybdenum covered with lab6 film field emitting cold cathode
而且，目前可借鑒的參考文獻較少，圍繞著前人做過的方案，本文做了大量工作，在已有文獻介紹的基礎上，結合原有的理論和實踐基礎，摸索出了包括高溫氧作用反應離子（ rie ）刻蝕法、濕法腐蝕法和電
化學腐蝕法在內的三種制備工藝，運用電
化學腐蝕工藝成功制備了單尖的六

Doping properties of mgb2 superconductor
硼化鎂超導體的摻雜性質
We expected that this dense vapor would diffuse into the solid boron, producing pellets of mgb2
我們預期這麼濃的蒸氣會擴散到固態
硼的內部，然後產生顆粒狀的
硼化鎂。
The results show that as the voltage rises, the tubes ’ discharge mechanism changes from glow discharge to arc discharge, the current rises suddenly and the voltage drops a lot
結果表明，隨著電壓的升高，六
