中文拼音 [jīnggébǐrè]
晶格比熱
英文
lattice specific heat-
The structures and characteristics of several graphite samples are measured by means of powder x - ray diffraction ( xrd ), brunauer - emmer - teller ( bet ) surface area measurement, inductively coupled plasma ( icp ) spectroscopy, particle size analysis and electrochemical measurements. the effects of origin, structure, impurity, particle size, specific surface area of carbon materials on the electrochemical characteristics are studied. a synthetic graphite with abundant resources, low cost and favorable performance is determined as the raw material for modification of graphite
採用xrd 、 bet 、 icp 、激光粒徑分析及電化學性能測試等方法，對國內外多種典型石墨樣品的結構與性能進行比較，研究石墨材料的來源、晶體結構、雜質含量、顆粒大小、比表面積等因素對其充放電性能的影響，確定一種性能較好、價格低廉、來源廣泛的普通人造石墨粉作為熱處理與摻雜改性、以及復合結構炭材料研究的原材料。Because the lattice vibration is weak at very low temperature, the contributions of electrics and other low energy excitations become dominant parts of specific heat. therefore, we can study the micromechanism of many physical phenomena from specific heat measurement
在很低的溫度下，由於晶格振動變得很弱，電子和低能激發貢獻越來越突出，這對我們通過低溫比熱研究很多現象的微觀機制十分有利。After extended the formula of normal state specific heat to the superconducting state, we obtain its electronic specific heat of superconducting state
擬合其正常態比熱，並把正常態的晶格比熱延伸到超導態后，在總比熱中減去，就得到mgb2在超導態的電子比熱。A ) the analyse of normal state specific heat of mgb2 shows : there is a strong einstain mode at about 310k. therefore its lattice specific heat composes of debye and einstain contribution
1 ）對mgb2正常態比熱的分析表明，在310k左右有一支強的愛因斯坦模，因此其晶格比熱應由debye項和愛因斯坦項構成。We have measured the low - temperature specific heat of mgb2, and analyzed thoroughly its lattice and electronic contribution respectively
本文測量了低溫下mgb2的比熱，並詳盡分析了mgb2的晶格比熱和電子比熱。However the study of metal - oxide hetero - interface is relatively less because the properties of metals and oxides usually differ extremely from each other. contrary to metals, the oxides are usually very brittle, elastically stiffer, insulating and exhibit less thermal expansion and their crystal lattice constants are different from metals. moreover, the preparation of specimen of metal - oxide interface is very difficult, the observation of searching a suitable interface under the electron microscope is also a tedious work
然而，對金屬-氧化物界面結構的研究卻相對少一些，這主要是由於金屬與氧化物之間的性質相差非常大，與金屬相反，氧化物通常很脆、絕熱、熱膨脹系數小，晶格常數也不同於金屬，有的甚至相差很大，而且，制備金屬-氧化物界面比較困難，在電子顯微鏡下全面地觀察一個合適的界面也是一項令人乏味的工作。Imagine that the heavy positive ions of the crystal lattice are held in place by strong springs ( the chemical bonds )
想像在晶格中，質量比較大的正離子被強力彈簧（代表化學鍵）所束縛，而熱能會激發離子以某些特定的頻率振動。分享友人
