Then, on the basis of above achieved constituent binary results, thermodynamic properties of 10 ternary liquid alioys (Cd-Bi-Pb, Cd-Pb-Sb, Cd-Pb-Sn, Mg-In-Cd, Zn-In- Cd, Cd-Bi-Sn, In-Bi-Pb, Sn-AgPb,Zn-In.Pb, Al-Cu-Zn), 3 quaternary ones (Cd-Bi-Pb-Sn, Zn-Sn-Cd-Bi, Zn-Sn-Cd-Pb) and 1 quinary. one (Zn-Sn-Pb-Cd-Bi) are predicted. For most of investigated multicomponent systems, the calculated activities are in good with the experimental ones, and in particular for multicompoment immiscible ones, the predicted results are satisfactory and exciting. At the same time, the comparison result between the three equations shows that Wilson equation and T-K-Wilson one are more stable than NRTL one, that maybe is because NRTL equation contains a third parameter, and so ,to some degree, Wilson model and T-K-Wilson model are superior to NRTL model. And also the comparison between local composition models and other models such as Pelton- Flengas?method, Krupkowski formalism, mass action concentration model and Hoch- Arpshofen model shows that local composition models are more convenient and credible.

在此基礎(chǔ)之上應(yīng)用局部組成型模型對10個三元液態(tài)合金（包括Cd-Bi-Pb中文无码视频t、Cd-Pb-Sb最新白嫩丰满美女AV网站、Cd-Pb-Sn、Mg-In-Cd色视频在线一区二区三区、Zn-In-Cd一级欧美黑人大战白妞、Cd-Bi-Sn18岁免费看的黄色网站、In-Bi-Pb、Sn-Ag-Pb色秀视频a8a6com、Zn-In-Pb国产精品老女人精品视频、Al-Cu-Zn），3個四元液態(tài)合金（包括Cd-Bi-Pb-Sn黄片A片三级aa黄、Zn-Sn-Cd-Bi免看一级a一片日韩A片、Zn-Sn-Cd-Pb）和1個五元液態(tài)合金（Zn-Sn-Pb-Cd-Bi）的活度進行了預(yù)測，預(yù)測效果良好a级黄片一级，尤其對Zn-In-Pb系和Zn-Sn-Cd-Pb等多元液-液共存體系熱力學(xué)性質(zhì)的預(yù)測也取得了令人滿意的結(jié)果日韩黄色视频品爱；同時對三個方程的比較分析表明：Wilson方程和T-K-Wilson方程在多元系熱力學(xué)性質(zhì)的預(yù)測中表現(xiàn)穩(wěn)定，而NRTL方程由于引入了物理意義不清楚的第三參數(shù)99热W亚洲精品国产99，使得其具有不確定性和不穩(wěn)定性的特點18禁片免费网站在线看，因此Wilson方程和T-K-Wilson方程較NRTL方程更為優(yōu)越；此外對局部組成型模型與其它模型（如Pelton-Flengas方程男人的天堂av社区在线、Krupkowski方程三级绝黄A片在免费线观看欧美、作用濃度模型和Hoch-Arpshofen模型）的比較表明：局部組成型模型同樣是優(yōu)秀的，甚至在某些方面更為簡便和可靠国语自产免费精品视频在。

The results show that Bi and Sb are mainly distributed on grains and grainboundaries, and Bi on grainboundaries there are mainly simple substance Bi particles, Sb in grains are intermetallics containing stibium. The tensile strength, yield strength, elongation and variation of area of halfhard brass containing bismuth and stibium are 478.9 MPa, 295 MPa, 15.1% and 29.3% respectively. Corresponding to HPb59-1, the cutting property of brass containing bismuth and stibium is excellent. The brass containing bismuth and stibium shows excellent dezincification corrosion resistance, and the depth is 323 μm.

結(jié)果表明：添加的Bi和Sb主要以單質(zhì)或化合物方式存在于無鉛黃銅的相內(nèi)和相界處全国最新的黄色视频播放久了爽爽，Bi以單質(zhì)顆粒存在于相界處，Sb以化合物形式存在于相內(nèi)亚洲欧美综合久久久久久小说，這對提高合金切削性能有利自拍偷拍小说区；添加Bi和Sb黃銅的抗拉強度為478.9 MPa，伸長率為15.1%日本一区,二区,三区AⅤ视频，斷面收縮率為29.3%99热精品区，屈服強度大約為295 MPa；添加Bi和Sb黃銅的切削性能比HPb59-1鉛黃銅的優(yōu)狼友视频在线的，合金的脫鋅腐蝕性能良好女人扒开腿让男人桶白浆动态视频，脫鋅層厚度約為323 μm。

The structure measurement indicates that only a small amount of Bi3+ ions can not enter the A-site of La2/3Ca1/3MnO3 lattice. Because of the low melting behavior of bismuth oxide, the superfluous Bi will segregate as insulating bismuth oxides and bismuthate. Because of the segregation of Bi, the surface of the main phase has different ferromagnetic property from that of the core, namely the magnetic inhomogeneity of the samples is enhanced, which results in the broader ferromagnetism-paramagnetism transition and magnetoresistance plateaus in samples with the high Bi content.
