基于家庭内部议价能力与社会规范两种解释，探究夫妻间住房产权归属与家庭教育投资的关系。利用CFPS数据实证发现，通过女性劳动参与和家庭收入两种机制，女性拥有住房产权促进了家庭教育投资绝对数额增加。异质性分析显示，伴随女性受教育水平提升与受教育水平性别差距缩小，住房产权对家庭教育投资的影响得以增强，另外二者间影响仅在男孩子代与独生子女样本中表现明显。进一步分析显示，相较于女性独有产权，夫妻共享住房产权对家庭教育投资的影响更大。

以乳清蛋白和果胶、葡聚糖为主要原料,采用酸诱导法制备乳清蛋白-果胶乳液凝胶(whey protein-pectin emulsion gel,WP)和乳清蛋白-葡聚糖乳液凝胶(whey protein-glucan emulsion gel,WG),比较35%、75%分散相体积分数凝胶(分别记为WP35、WG35、WP75、WG75)的功能特性,并进一步探究高内相乳液凝胶作为脂肪替代物在低脂再制奶酪中的代脂效果。结果表明:WP75的平均粒径最小,脂肪分布均匀,蛋白质网络结构稳定。乳液凝胶样品在0.1~10 Hz内弹性模量(G′)和黏性模量(G″)都随油相体积分数的升高呈上升趋势,其中WP75抵抗形变能力、热稳定性及持水性都优于其他样品。样品15%-WP75(添加WP75,脂肪质量分数15%的再制奶酪)油析性减弱,熔化性增强,质构特性与全脂对照无明显差异。研究表明乳清蛋白与果胶制备的高内相乳液凝胶在低脂奶酪产品有较好的脂肪替代效果,在低脂乳制品加工中具有良好的应用潜力。

Electromagnetic emissions from electrical information equipment may contain useful information and lead to information leakage. In order to detect the electromagnetic information leakage of digital video cable,a rapid testing method for computer video information leakage detection without reconstructing the displayed image is proposed. In this method, the electromagnetic radiation spectrum of typical image transmitted by HDMI cable is simulated. Then the electromagnetic radiation spectrum of the computer when transmitting the same image as the typical image is obtained by conduction and radiation EMC test methods. Finally, the correlation between the spectrum of simulation and the test spectrum is analyzed, and the correlation coefficient is used to judge whether the computer has produced the electromagnetic leakage of video information. The analysis and test results show that when the correlation coefficient is greater than 0.5, the electromagnetic leakage of computer video information can be judged.

Amphiphilic diblock copolymers self-assemble into a variety of micellar structures with diverse shapes in selective solvents. Here, we study the concentration and temperature dependence of the packing structure of spherical micelles of a polyisoprene-b-poly(2- vinylpyridine)(PI-b-P2VP) diblock copolymer in toluene using synchrotron radiation small angle X-ray scattering (SR-SAXS) and atomic force microscopy (AFM) techniques. Randomly packed spherical micelles are detected in dilute solutions, while in concentrated solutions, face-centered cubic (FCC), body-centered cubic (BCC) mixed crystal structures, and pure BCC crystal structures are observed with an increase in concentration. In situ SAXS experiments on the FCC/BCC mixed crystal structures reveal a novel FCC/BCC → BCC → Disorder → BCC phase behavior during the thermal annealing process. These results demonstrated that the BCC phase is apparently more stable than the FCC phase in the current sphere-packing system and FCC/BCC is a metastable state. The incompatibility of the PI and P2VP blocks decreases at a higher temperature and renders the variation of domain spacing.

This paper presents a novel stochastic collocation method based on the equivalent weak form of multivariate function integral to quantify and manage uncertainties in complex mechanical systems. The proposed method, which combines the advantages of the response surface method and the traditional stochastic collocation method, only sets integral points at the guide lines of the response surface. The statistics, in an engineering problem with many uncertain parameters, are then transformed into a linear combination of simple functions' statistics. Furthermore, the issue of determining a simple method to solve the weight-factor sets is discussed in detail. The weight-factor sets of two commonly used probabilistic distribution types are given in table form. Studies on the computational accuracy and efforts show that a good balance in computer capacity is achieved at present. It should be noted that it's a non-gradient and non-intrusive algorithm with strong portability. For the sake of validating the procedure, three numerical examples concerning a mathematical function with analytical expression, structural design of a straight wing, and flutter analysis of a composite wing are used to show the effectiveness of the guided stochastic collocation method.
