Revista mexicana de física , 2008,
Abstract: radiation effects of high energy electrons on pure and additively colored (ac) kcl and kbr crystals have been studied by optical absorption in the 200-800 nm range at rt. besides the main f-center related absorption band at 553 nm, the f+2 (670 nm) and f2 (740 nm) bands (r1 and r2 centers in old notation) ascribed to f centers aggregates in additively colored kcl are clearly observed. after electron irradiation with energy of 1.0 me v and doses of 100 kgy or 3.5 me v and 180 kgy, the f+2 and f2 bands are strongly diminished, the intensity of the f bands is increased and its peak lightly shifted to low energy at 558 nm. in kbr, the related absorption band maximum for the pure and ac samples after irradiation shows the same peak position as the f-center absorption. for ac kbr the intensity of this peak versus accumulative doses shows a maximum around 300 kgy but in pure kbr the peak continuously increases. in contrast, kcl does not show such dependence on accumulative doses. for both samples, the electron irradiation induce at least two bands in the 210-300 nm (uv bands) range that has been related with hole centers (v bands). the results have been analyzed in terms of surface close f centers and alkali and halogen ions desorption processes.

Besides the main F-center related absorption band at 553 nm, the F+ 2 (670 nm) and F2 (740 nm) bands (R1 and R2 centers in old notation) ascribed to F centers aggregates in additively colored KCl are clearly observed. After electron irradiation with energy of 1.0 MeV and doses of 100 kGy or 3.5 MeV and 180 kGy, the F+ 2 and F2 bands are strongly diminished, the intensity of the F bands is increased and its peak lightly shifted to low energy at 558 nm. In KBr, the related absorption band maximum for the pure and AC samples after irradiation shows the same peak position as the F-center absorption. For AC KBr the intensity of this peak versus accumulative doses shows a maximum around 300 kGy but in pure KBr the peak continuously increases. In contrast, KCl does not show such dependence on accumulative doses. For both samples, the electron irradiation induce at least two bands in the 210-300 nm (UV bands) range that has been related with hole centers (V bands).

Abstract: 本文利用透明槽技术、电化学循环V-A法及量子化学EHMO三种方法,研究了La在KCl-NaCl(11mol)及LaCl_3-KCl-NaCl熔体中的溶解行为。初步认为溶解在KCl-NaCl熔体中的La是以中性金属状态存在。在LaCl_3-KCl-NaCl熔体中,溶解的La与La~(3+)作用生成低价La~(2+)离子,La~(2+)又与周围的La~(3+)作用形成原子簇离子La_m~(n+)赋存于熔体之中。

Abstract: 自康普顿散射提出以来,其理论研究和应用研究一直是国内外的热点。基于NaCl和KCl溶液的康普顿散射,通过一定的近似处理,从理论上分析适合这两种溶液的康普顿散射光子数与溶液浓度之间的关系表达式;然后,通过康普顿散射实验验证康普顿散射的理论和实验研究。为了从更微观的角度来把握NaCl和KCl溶液康普顿散射的机理,笔者立足于密度泛函理论对NaCl与KCl溶液的电子结构作了深入分析,得出结论:除质量密度、散射衰减因子以及溶液的浓度外,电子数密度和电子受到的束缚也对康普顿散射光子数有影响,其中,电子数密度是影响NaCl与KCl溶液康普顿散射光子数的主要因素。
The compton scattering of solution is a very meaningful aspect. On the basis of the Compton scattering of NaCl and KCl solution, we analyzed the relation expression between the Compton scattering photon number and the concentration of the solutions in theory by processing certain rational approximation, and then verified it through Compton scattering experiments. In order to grasp the micro-mechanism of Compton scattering of NaCl and KCl solution, we deeply analyzed the electronic structure of NaCl and KCl solutions according to the density functional theory. It is concluded that the factors influencing the Compton scattering photon number include electron number density, electron bound of scatterer, mass density, concentration of solutions and scattering attenuation coefficient, among which electron number density is the main factor

Abstract: ?用kcl5%、6.5%、8.5%、12.5%不同质量分数的替代量部分替代nacl进行咸蛋腌制,25%的饱和食盐水浸泡作为腌制对照组,通过这种混合腌制的方法可直接降低食盐的添加量,改善腌制过程中咸蛋白口感偏重的问题,以腌制出品质优良的低盐咸蛋;另外,对咸蛋中nacl含量、蛋黄出油率、水分的相关理化指标、质地结构、色度及对微观结构影响的测定,并且对咸蛋品质进行综合感官评定。结果表明:用6.5%部分替代nacl组较好,蛋清nacl含量从54.4mg/g降到40.1mg/g,降幅为26.29%。感官评定的结果表明:k含量过多会有苦涩味,用kcl替代物的方式腌制的咸蛋质地结构、蛋黄松沙、出油口感上没有明显的差异性,所以用kcl部分替代法降低咸蛋na含量是可行的。
