例句與用法

  1. The entropy or number of states of system or subsystem are closely related to interaction of particles and energy level distribution , therefore , to study the temperature dependence of the specific heat may supply some important and useful microscopic information which may play an important role in understanding electronic structure , density of state , phonon spectrum etc . the specific heat measurements at low temperatures also play important roles in the finding of the third law of thermodynamics , the quantum theory of solid and bcs theory for superconducting etc . moreover , specific heat measurements help us to understand the different kinds of phase transitions ( such as : structural phase transition , magnetic phase transition , superconducting phase transition etc . ) and the scaling behavior near the critical point
    系統(tǒng)、子系統(tǒng)的熵或微觀狀態(tài)數(shù)與微觀粒子間的相互作用及能級(jí)分布密切相關(guān)，因此研究比熱與溫度的依賴(lài)關(guān)系能夠提供被測(cè)量系統(tǒng)許多極其有用的微觀信息，對(duì)理解固體的電子結(jié)構(gòu)、電子態(tài)密度、聲子譜等起著十分重要的作用。低溫比熱的測(cè)量和研究對(duì)熱力學(xué)第三定律、固體量子理論和超導(dǎo)bcs等理論的建立起到了積極的推動(dòng)作用。比熱研究還有助于認(rèn)識(shí)各類(lèi)相變?nèi)缃Y(jié)構(gòu)相變,磁性相變,超導(dǎo)相變等及臨界點(diǎn)附近的標(biāo)度規(guī)律。
  2. But in the moderate electric field 150 kv / cm , there is a sharp change in the configuration and charge distribution of the exciton , i . e . the exciton is directly split into an electron polaron and a hole polaron . the polarization and dissociation happen at a same time , which differs from that in conjugated polymers . and in the strong electric field 350 kv / cm , appear structural phase transition of the chain and luminescence quenching
    同時(shí)得到兩個(gè)重要的臨界電場(chǎng)值： 1激子解離電場(chǎng)ec1 （ 150kv / cm ） ，在此電場(chǎng)下激子發(fā)生瞬間解離，成為電子型極化子和空穴型極化子； 2結(jié)構(gòu)相變電場(chǎng)ec2 （ 350kv / cm ） ，在ec2下二聚化晶格開(kāi)始被等距晶格取代， ptcl絡(luò)合物鏈發(fā)生結(jié)構(gòu)相變，并伴隨peierls能隙漸趨消失和發(fā)光猝滅的現(xiàn)象出現(xiàn)。
