简介：吸收系列和折射索引变化在一个核心/壳量点为激子理论上被计算。我们的方法论的优点是一个人能由在监禁潜力改变二个参数调查排斥核心的影响。光吸收上的激子量点的维数效果被学习了。在一样的政体，激子的光吸收紧张比为二维的量戒指为核心/壳量点是小得多的，这被发现了。线性并且非线性的光吸收系数和折射索引变化与监禁潜力的变化被检验了。结果证明光吸收和折射索引变化被核心/壳量点的排斥核心强烈影响。而且，计算结果也表明作为内部半径增加，山峰系数和激子的折射索引变化将显示出的吸收珍视在核心/壳量点的光Aharonov-Bohm摆动。

简介：被尝试在basmati米饭决定质的变化(PusaBasmati1121，PB1121)在在40 浸泡期间；°C到80 ；°C。浸泡温度有重要效果(=0.01)在化学作文，glycemic索引和米饭的淀粉特征上。淀粉内容，明显的直链淀粉内容，粗略的蛋白质内容和在未浸泡的米饭满意的粗略的脂肪被发现分别地，是73.24%，27.26%，8.79%和2.56%，但是这些特点地的差别在浸泡以后被观察。到胶淀粉比率(Am/Ap)的直链淀粉从0.59～0.52减少了(在80点浸泡了 ；°C)。粗略的纤维和粗略的灰内容在浸泡以后增加了。在浸泡米饭的矿物质作文(K，P，S，Ca，Mg，Mn，Fe，Cu和Zn)在擦亮的一样的度被发现是16.46%比未浸泡的米饭高。未浸泡的米饭的Glycemic索引被发现是58.41，但是在在80 浸泡以后减少了到54.31；°C。粘贴性质，扫描电子显微镜图象，和X光检查diffractograms在60 的温度范围建议了淀粉的部分gelatinization；°C到80 ；°C。在米饭(明显的直链淀粉内容，Am/Ap比率和crystallinity率)基于质的变化，这被结束中间的浸泡温度(60 ；°C到70 ；°C)将为PB1121浸泡有用。
