基于马克思社会再生产理论的推导,可知社会再生产的平衡条件成立与否取决于第Ⅰ部类的积累率,长期平衡的基本特征是两大部类增长率相等。根据中国31个省份5年的投入产出表测算出各省两大部类历年的关键指标,可展开两方面的实证研究:一是考察中国社会再生产的平衡条件和长期平衡情况;二是构建动态面板模型探讨中国社会再生产平衡条件的实现和长期不平衡的修正。结果发现:第一,在全国和东中部地区存在着积累不足的问题,而西部地区则出现了积累过度的问题,表明中国社会再生产平衡条件未得到满足;第二,全国和东中西部地区的第Ⅱ部类增长率均小于第Ⅰ部类增长率,这意味着中国社会再生产在长期内也是不平衡的。第三,无论是平衡条件的实现,还是长期不平衡的修正,提高两大部类的资本有机构成都是最为关键的环节。而且,修正社会再生产不平衡与构建国内大循环具有内在逻辑上的一致性。

以桃浆为基质,添加卡拉胶辅以赤藓糖醇为共溶质,通过热风干燥脱水制作成重组桃脯,探究赤藓糖醇添加量(0%,1%,5%,9%)对重组桃脯品质特性的影响。结果表明:随着赤藓糖醇添加量的增加,水分子流动性和干燥速率降低。色泽分析结果表明:随着赤藓糖醇添加量的增多,重组桃脯亮度值l*逐渐增大,最大值为52.87±5.04,红绿度a*逐渐降低,最低值分别为10.88±1.20和17.40±1.75。风味分析结果表明:电子鼻传感器W1C、W3C、W5C响应值较大,且其响应值随赤藓糖醇添加量的增加而增加,PCA分析表明添加赤藓糖醇的桃脯风味与对照组差异显著。质构分析结果表明:赤藓糖醇添加量为9%时,桃脯的硬度、咀嚼性和胶着性最大,分别为30.51,7.21 N和14.42 N,而内聚性显著降低,赤藓糖醇添加量对重组桃脯弹性无显著影响。随着赤藓糖醇添加量的增加,重组桃脯的皱缩度逐渐减小,1%,5%,9%处理组与对照组相比分别下降了4.00%,12.25%,17.75%。低场核磁结果表明:赤藓糖醇显著改变了水分子的流动性,5%和9%处理组重组桃脯中低流动性水分占比增加。拉曼光谱显示:随着赤藓糖醇添加量的增加,位于2 918 cm-1附近的振动峰逐渐变得尖锐,表明桃浆-卡拉胶-赤藓糖醇体系中氢键的形成有助于致密结构的构成,宏观表现为重组桃脯良好的质构品质。

Using the technique of integral within an ordered product (IWOP) of operators we show that the wavelet transform can be recasted to a matrix element of squeezing-displacing operator between the mother wavelet state vector and the state vector to be transformed in the context of quantum mechanics. In this way many quantum optical states'wavelet transform can be easily derived.
