Coupling Effects of Depletion Interactions in Three-Sphere Systems with Different Size Ratio of Large- to Small-Sphere

The coupling effects of depletion interactions in three-sphere systems with different size ratio of large- to small-sphere are studied by Monte Carlosimulations in this paper. The numerical results show that this coupling effect is affected by the size ratio of large- to small-sphere: the larger the size ratio is, the larger the coupling effect will be.

Coupling effects of depletion interactions in a three-sphere colloidal system

In a three-sphere system, the middle sphere is acted upon by two opposite depletion forces from the other two spheres. It is found that, in this system, the two depletion forces are coupled with each other and result in a strengthened depletion force. So the difference of the depletion forces of the three-sphere system and its corresponding two two-sphere systems is introduced to describe the coupling effect of the depletion interactions. The numerical results obtained by Monte- Carlo simulations show that this coupling effect is affected by both the concentration of small spheres and the geometrical confinement. Meanwhile, it is also found that the mechanisms of the coupling effect and the effect on the depletion force from the ~eometry factor are the same.

三同心球光学系统跟瞄误差分析

针对独有的跟踪方式,具体讨论了激光通信三同心球光学系统的跟瞄方案,并进行了具体规划。通过对通信跟踪光路和通信接收光路的视场和精度分析,给出了二者的相关参数,作为Matlab理论计算跟踪像面轨道的依据。利用Tracepro软件模拟了引入相关误差量后的通信跟踪和通信接收像面光斑质心偏移和光斑大小变化情况。仿真结果显示:随着角度的旋转,通信接收的质心偏差在±4μm范围内,通信跟踪的质心偏差在±50μm范围内;通信接收像面光斑直径小于80μm,通信跟踪像面光斑直径均在400μm以内。系统所引入的误差在允许范围之内,不影响相关跟踪通信功能。

Coupling Effects of Depletion Interactions in Colloidal Suspensions

The depletion interactions of the three-sphere system in which the three spheres are on one line are studied by Monte Carlo simulations. The depletion interactions are determined by ARM, and the coupling effect was proved by the numerical result that the depletion interactions in the three-sphere system are larger than that of the corresponding two-sphere system. Furthermore, we find that the mechanisms of the coupling effect and the effect on depletion force from the geometry factor are the same. In addition, the numerical results also show that this coupling effect will be affected by both the volume fraction and separation of three-sphere system.

中国式现代化的理论内涵与测度指标体系——基于生产发展、生活富裕和生态良好的协同发展研究

推进以绿色为底色的生产发展、生活富裕和生态良好(以下简称“三生”)的协同发展,是实现中国式现代化的根本之道。本文立足于马克思关于人的全面发展、五大文明和中国式现代化理论,阐述了三生协同发展与中国式现代化的内在关系,构建三生协同发展指标体系测度了中国式现代化发展水平及结构调整趋势,研究发现:三生协同发展是中国式现代化的核心要义,与五大文明和中国式现代化五大特征在不同层面相互呼应;2011—2019年,我国三生协同的现代化发展水平和结构得分分别从0.24、0.28增长至0.35、0.33,呈稳定上升和优化趋势,在区域间现代化协调发展、全体人民共同富裕等方面取得了重大成就;但仍面临生产发展内部协调受限、共同富裕发展不充分、物质文明与精神文明相协调的结构尚未形成等挑战,各级政府须深化高质量发展并扩大内需,推动生活质量提升和物质文明精神文明协同,加速绿色发展,以推进中国式现代化。
