fermi n.【物理學】費密〔長度單位,等于10-13厘米〕。

fermion

The most recent delay came at the end of march , with the dramatic failure of a magnet assembly that had been supplied by cern ' s american counterpart , the fermi national accelerator laboratory ( fermilab ) near chicago 最近一次推延是在三月底,原因是磁鐵裝配嚴重失敗,而負責裝配的是位于芝加哥附近的美國同行費爾米國家加速器研究所。

Using the fully consistent rrpa method , we have studied the properties of collective multipole excitations for several closed - shell and closed sub - shell nucleus in the isoscalar modes and isovector modes 計算結果顯示,從fermi海核子態到dirac海負能核子態形成的對激發在核的集體激發中的貢獻很重要,尤其是對核的同位旋標量激發模式。

We also discuss the statistical relations of the majorana lattice fermions and the majorana fermi fields respectively . chapter3 : new jordan - wigner - rype transformation between spin - 3 / 2 and fermions of two types is shown 第三章:介紹了在自旋- 3 2的自旋算符和雙費米子之間構建出的一種新的“ jordan - wigner ”類型的變換。

The reason is perhaps that the method of high - pressure sinter changes the shape of the fermi faces , and reduces the contribution of one pair of fermi faces and increases the contribution of the other 其原因可能是高壓燒結改變了費米面的形狀,使得一組費米面的電子的貢獻減小,另一組費米面的電子的貢獻增大。

The thermodynamics properties of the fermi system and the boson system at high temperature and low density without arrliel field is discussed and the valuable result is also educed 摘要討論了費米子系統和玻色子系統在無外場作用下高溫低密度條件下的熱力學性質,得到了有益的結果。

The most important experiment is occurring at the upgraded tevatron collider at fermi national accelerator laboratory in batavia , ill . , which began taking data in 2001 這個實驗有可能直接產生那難以捉摸的希格斯玻色子,如此一來,標準模型里的粒子就全都找到了。

For fermi system , the finite number effect adds a negative correction to the fermi temperature in 3d , 2d cases , whereas has no effect on 1d case 有限粒子數效應降低了體系的實際的fermi溫度,這個差別也是由位勢的頻率分布和粒子數n決定的。

Hole is an charged electronic entity in semiconductors and insulators which have energies less than the fermi level and participate in the electric conduction 空穴是半導體和絕緣體中的一種帶電體,其能量小于費米能,并且參與導電。

The quantization of the system of one electron in four sites and the vibration of h2o with fermi resonance were studied by the lyapunov analysis 運用李雅普諾夫指數對h2o振動體系及多個格點中單電子體系的量子化問題進行研究。

Forty seconds later , the shock waves reached the base camp where the italian - american physicist enrico fermi and his team stood 40秒鐘以后,這個震動波傳到了美籍意大利人、物理學家恩里科?費米和他的隊員們所駐扎的基地。

1942 the world ? s first nuclear chain reaction took place at the university of chicago , under physicists enrico fermi and arthur compton 物理學家恩里科?費米和阿瑟?康普頓在芝加哥大學進行了世界第一次原子彈核連鎖反應。

Pomeranchuk , i . ya . “ instabilities of landau fermi - liquid via spontaneous fermi surface deformations . “ sov . phys . jetp 8 ( 1959 ) : 535 藍道費米液體與自發性費米表面破壞的不穩定性, 《實驗與理論物理學報》 8 ( 1959 ) : 535

Ultimately the value of dealing with everyday problems the way fermi did lies in the rewards of making independent discoveries and inventions 最后,以費米處理問題的方式解決日常問題的價值在于獨立發現和發明的回報。

Since fermi ' s death in 1954 , no physicist has been at once a master experimentalist and a leading theoretician 自1954年費米去世后,還沒有哪一位物理學家同時是一名精通的實驗主義者和一名最主要的理論家。

Two can indeed easily be explained as first overtones ( see table 115 ) which occur strongly because of fermi resonance 另外兩條的確很容易解釋為第一泛頻(參看表115 ) ,它們的強度由于費密共振而增強。

After a mental calculation , fermi announced to his team that the bomb ' s energy had equated 10 , 000 tons of tnt 經過大腦計算,費米向他的隊員們宣布爆炸的原子彈的能量相當于1萬噸烈性炸藥。

Manhattan project : a team led by enrico fermi initiate the first self - sustaining nuclear chain reaction 1942年曼哈頓計劃:一支由恩里科?費爾米率領下的小組啟動了第一條自給核反應鏈。

To develop this talent in his students , fermi would suggest a type of question now known as a fermi problem 為了開發他的學生們的才能,費米會提出一種現在稱之為費米問題的問題。
