  • The stabilized chemical potential diagrams combined with the equilibrium phase diagrams of mo-si-c ternary system arid the principles of thermodynamic, kinetic, mass-balance could be applied to analyzing and judging reaction paths of in situ synthesis of mosi2-sic composites through solid-state displacement reactions theoretically . 3
    該相圖結(jié)合平衡相圖和熱力學(xué)、物料平衡、動(dòng)力學(xué)原則,可以作為分析和判斷固態(tài)置換反應(yīng)原位合成mosi_2-sic復(fù)合材料反應(yīng)路徑的理論依據(jù)之一,并從理論上分析了固態(tài)置換反應(yīng)原位合成mosi_2-sic復(fù)合材料可能的反應(yīng)路徑。
  • A new interface-perturbation model of solid-state displacement reactions ternary system is suggested and the interface-stability criterion is derived in the form of chemical potential if the chemical potential of rate-control-element at frontier of tiny perturbative zone goes up less than 20.7 %, linear interface will grow up stablly and form layered structure; if it goes up more than 20.7 %, linear interface is not stable and will form aggregate structure
    通過(guò)建立界面擾動(dòng)模型,推導(dǎo)了三元固態(tài)置換反應(yīng)系界面穩(wěn)定性的化學(xué)勢(shì)梯度判據(jù)。結(jié)果表明:如果擾動(dòng)微區(qū)前沿速率控制元素的化學(xué)勢(shì)梯度升高小于20.7,平面界面穩(wěn)定長(zhǎng)大,將形成層狀結(jié)構(gòu);若大于20.7,平面界面不穩(wěn)定長(zhǎng)大,將形成束集型結(jié)構(gòu)。
  • In the case of the unsaturated alcohols, such as hydroxyethyl acrylate ( hea ), the paes showed the photo-alignment property to the nematic liquid crystals with the pretilt angle of 0.60 ? secondly, three kinds of fluoro-containing diamine monomers were prepared via the reduction reactions of the corresponding dinitro compounds, which were synthesized via the nitro nucleophilic displacement reactions of 3, 5-dinitro-5-trifluoromethyl benzene with diphenol compounds
    此外,本論文還設(shè)計(jì)并通過(guò)3,5-二硝基三氟甲苯與二酚化合物的硝基親核取代反應(yīng)制備了二硝基化合物,將其還原最終合成了三種間位取代的含氟二胺單體tfpda、tfbpda與tfmda,并對(duì)其聚合行為進(jìn)行了研究。
  • In this paper, the kaolinite / polyacrylamide intercalation compound was prepared first by the displacement reaction of kaolinite / formamide intercalation precursor with acrylamide, and then the in-situ polymerization of acrylamide . the kaolinite structure and the intercalation mechanism were discussed by the techniques of powder x-ray diffraction analysis, * h mas nmr, raman, and ir spectra
    本文以甲酰胺為前驅(qū)劑、丙烯酰胺為取代劑,采用插層-取代-原位聚合的方法制備高嶺石有機(jī)插層復(fù)合物,用x射線衍射、~1hmasnmr、raman、ir等技術(shù)研究了插層復(fù)合物結(jié)構(gòu)特征和插層反應(yīng)機(jī)理。
