不同于家庭现代化理论中个人主义和平等主义的亲和,夫妻关系的平等化和代际团结并存于当代的中国家庭。考察夫妻关系的平等化,需要关注行动主体、婚姻家庭中的性别差异和对差异的具体定义。在苏南地区,以家庭为单位追求对等双系权利的两头婚实践中,双方家庭通过对传统的传嗣伦理、性别文化、照料劳动、经济付出等不同价值的通约和赋值而得到一个公平的总体判断。这种公平的积极叙事中隐含个人偏好和妥协,女方家庭和部分女性需要作出更大妥协。再造的传宗接代伦理为婚姻公平带来了议价空间,但由于代际的紧密联系,亦带来了子代自主权受限的问题。随着婚姻生活日益理性化,女性经济独立和经济地位的提升,婚姻内的不确定性增长,以代际为单位寻求家庭利益最大化或成中国式亲密关系的新趋势。

We investigate the polarization properties of harmonics from the cyclic H_(3)^(2+) molecular ions in tailored bichromatic counter-rotating circularly polarized(BCCP)fields by solving the time-dependent Schrödinger *** allowed harmonics and their helicities are associated with the symmetry compatibility of the field-target systems,and large intensity difference between adjacent harmonics with opposite helicities appears in a wide spectral range when the BCCP field is at certain rotation *** try to explain the intensity difference by using a recombination model based on the quantum-orbit theory and by analyzing the ionization ***,to synthesize attosecond pulse trains with tunable polarization,the intensity difference is manipulated by introducing a seed XUV field,and by changing the relative amplitude ratio as well as the helicity of BCCP fields.

开展城市洪涝灾害风险评估工作是防灾减灾的基础和决策手段之一,已成为当前研究的热点和趋势。首先从城市洪涝灾害的概念和形成机制入手,将致灾因子危险性、孕灾环境敏感性、承灾体脆弱性和防灾减灾能力作为一级指标。以年平均降雨量、水系距离、高程、地形起伏度等14个二级指标为基础,建立风险评估指标体系。采用随机森林算法、层次分析法和熵值法相结合的方法对指标进行排序和赋权,得到各评估指标的组合权重。以武汉市为研究区域,将各指标权重输入到风险评估模型中,在ArcGIS中进行空间分析和栅格计算,得到研究区危险性、敏感性、脆弱性、防灾减灾能力风险区划图以及综合风险等级分布结果。
