This article points out a misconception in physical chemistry " the value of gibbs function is equal when binary system of pure substance is in phase balance " 摘要指出了“單元復(fù)相系平衡狀態(tài)時(shí),兩相中的吉布斯函數(shù)值相等”說(shuō)法的錯(cuò)誤。
The basic thermodynamic theory was introduced to calculate the gibbs function changes of mg - si - 0 system and was used to discuss the process of synthesizing the mg2si powder 本文應(yīng)用熱力學(xué)理論對(duì)mg _ 2si制備過(guò)程進(jìn)行了討論,并探討了固相反應(yīng)進(jìn)行的可能性及工藝制度的確立。
For the profound comprehending of gibbs function and conditions of phase balance , the paper deduces one of the phase balance conditions is the chemical potential being equal in different phases 通過(guò)對(duì)吉布斯函數(shù)定義的再認(rèn)識(shí)和單元兩相系平衡條件的推導(dǎo)得出單元復(fù)相系相平衡的條件之一是具有強(qiáng)度性質(zhì)的各相化學(xué)式相等。
After getting thermo - chemical data of some compounds by using gaussian 98 software of quantum chemistry and obtaining activities of elements in ti matrix , the gibbs function increments , rg , for 16 chemical reactions at the interface of 12 scs - 6 sic / ti composites were calculated 結(jié)合量子化學(xué)研究結(jié)果,計(jì)算了scs - 6sic纖維與ti - al金屬間化合物和典型的近、 + 、近及鈦合金組成的復(fù)合材料體系可能發(fā)生的16個(gè)界面反應(yīng)的gibbs函數(shù)變_ rg 。
At first , basic thermodynamic theories were introduced to calculate the gibbs function changes of mg - si - o - c system , which was an effective tool for verifying the variation of composition during the solid - state reaction process . the possibility of the occurrence for solid - state reaction was discussed 論文應(yīng)用熱力學(xué)理論對(duì)mg - si基熱電化合物固相反應(yīng)過(guò)程中涉及的mg - si - o - c體系進(jìn)行了熱力學(xué)計(jì)算,探討了固相反應(yīng)發(fā)生的可能性及工藝制度對(duì)材料組成、性能的影響。
Because of the existence of the holes in the system , the molecular fraction q should considered into the free energies and the gibbs functions . when there are few holes or none existing in the system , i . e . , , it corresponds to the liquid state or solid state ; when there are lots of holes and a few atoms existing in the system , i . e . , , it corresponding to the gas state 為了進(jìn)一步研究固、液、氣三相之間的轉(zhuǎn)變,我們引入空格點(diǎn)并定義了占據(jù)率q ,當(dāng)空格點(diǎn)幾乎沒(méi)有或很少時(shí),即q 1 ,系統(tǒng)對(duì)應(yīng)的是固態(tài)或液態(tài);而當(dāng)空格點(diǎn)很多時(shí),即q 0系統(tǒng)中原子很少,系統(tǒng)對(duì)應(yīng)的則是氣態(tài)。
