  1. The valence electron structures of maid phases and phase interphase boundaries in al - li - cu based alloy were analyzed according to the empirical electronic theory in solid and molecules ( eet )

    本文運用固體與分子經驗電子理論（簡稱eet理論） ，對al - li - cu系合金相空間和相界面的價電子結構進行計算。
  2. In the models, the time dependent parabolic equations, deduced from the mild slope equations with currents or not, are used as the governing equations. based on the general conditions for open and fixed natural boundaries with an arbitrary reflection coefficient and phase shift, the boundary conditions for the present models are treated. the alternative direction implicit method is used to solve the governing equations and the numerical schemes are unconditional stable

    在建立模型時，將原始的橢圓型緩坡方程的近似型式? ?依賴時間變化的拋物型方程，作為控制方程；從將開邊界條件、不同反射特性的固壁邊界條件相統一的表達式出發，對邊界條件進行處理；用adi法數值求解控制方程，格式無條件穩定；節省了計算機內存和計算量。
  3. Among them, 3 plates always lies in the grain boundaries. following the initial region, single p phase region and in2tes phase region are formed in order

    在晶錠末端形成in _ 2te _ 3單相區，該相區晶界處有te夾雜相。
  4. By congruent ordering, a nonstoicheometric single ordered phase is produced with the order domains being separated by antiphase domain boundaries ( apbs ). spinodal decomposition occurs predominantly at apbs, which results in the replacement of the apbs by the two order / disordered interfaces ; spinodal decomposition at apbs promotes the decomposition in domains, however, the disordered phase in domains disappear as time follows

    失穩分解為一特殊的分解類型，主要發生在反相疇界處，並形成無序相，反相疇界處的失穩分解促進疇內的失穩分解，在疇內形成無序相，但隨時間延續，疇內無序相逐漸消失。
  5. The boundaries of phase transitions are at

    其相轉變邊界依次為：
  6. Piezoelectric properties were detected, it is suggested that the optimum poling condition is maintaining 15 minutes under 4kv / mm, poling temperature is 70 xrd results indicate that the fabric transited from rhombohedral to tetragonal gradually with the substitution of the ba2 +. morphotropic phase boundaries ( mpb ) of the ceramic exist in the composition range of x = 0. 06 ~ 0. 10

    Xrd分析表明，隨著ba ~ （ 2 + ）取代量的增加，樣品晶體結構逐漸由三方相向四方相轉變，在x = 0 . 06 0 . 10組成范圍內存在三方、四方相共存的準同型相界。
  7. Tempering can cause the boundary of main phase more straight and regular, and the quantity of micro - particles in the grain boundary will increase and these particles nail the neighbor boundaries. the co - effect of these factors improved the cocercivity of magnets

    時效使主相晶界平直規整，從而使反磁化疇難以形核；同時，晶界中的微粒相數量增多，這些微粒相強化了對晶界相的釘扎作用。
  8. Compared with cmo and cpm, scm had many advantages not only simpling preparation process, lowing calcining and sintering temperatures, shorting reacting time, but also preparing ceramics with excellent dielectric properties. with identical calcining conditions, the content of perovskite phase in calcined powders prepared by scm was much higher than that by cmo, what ' s more, by scm, the sintered ceramics had clear crystal boundaries, large - sized crystal grains and high density

    、 pbo bi仙混合助燒劑（摩爾比為1 ： 1 ： 1 ）都達到了理想的助燒效果，可將燒結溫度降低到900oc ，且介電性能優良，樣品介電常數分別不小於is000和22000 ，介電損耗分別不大於0
