Realistic animation of various interactions between multiple fluids, possibly undergoing phase change, is a challenging task in computer graphics. The visual scope of multi-phase multi-fluid phenomena covers complex tangled surface structures and rich color variations, which can greatly enhance visual effect in graphics applications. Describing such phenomena requires more complex models to handle challenges involving the calculation of interactions, dynamics and spatial distribution of multiple phases, which are often involved and hard to obtain real-time performance. Recently, a diverse set of algorithms have been introduced to implement the complex multi-fluid phenomena based on the governing physical laws and novel discretization methods to accelerate the overall computation while ensuring numerical stability. By sorting through the target phenomena of recent research in the broad subject of multiple fluids, this state-of-the-art report summarizes recent advances on multi-fluid simulation in computer graphics.

A practical chemical synthesis of L-camitine （1） has been accomplished from （R）-3-chloro-1,2-propanediol （（R）-4）, which is a main by-product originated from （R,R）-Salen Co（III） catalyzed hydrolytic kinetic resolution （HKR） of （±）-epichlorohydrin. （R）-4 was utilized as a chiral starting material to prepare the key intermediate cyclic sulfite （（R）-S）. The new synthetic approach demonstrated an efficient utilization of organic by-product for the asymmetric synthesis of bioactive compounds.

A metal-organic coordination polymer, [Cd（C15H10N4）（C6H8O4）]2n （1, C15H10N4： 2-methyl-pyrazino-[2,3-f][1,10]-phenanthroline （mpphen）, C6H8O4： adipate）, was synthesized via hydrothermal synthesis. The polymer was characterized by elemental analysis, IR, TG and single-crystal X-ray diffraction. X-ray diffraction shows that 1 is a cadmium polymer constructed by adipate-bridged dmuclear clusters, and each adipate connects two clusters to form a two-dimen- sional planar structure. Crystal data for 1： monoclinic, space group C2/c, a = 22.403（9）, b = 16.039（6）, c = 13.808（6） A, β= 125.262（6）°, V = 4051（3） A3, Mr = 502.79, Dc = 1.649 g/eraa, μ（MoKa） = 1.114 mm^-1, F（000） = 2016, Z = 8, the final R = 0.0509 and wR = 0.1054 for 1509 observed reflections （I 〉 2σ（I））.

为提高原子力显微镜(atomic force microscope,AFM)中微悬臂梁分布参数模型的精度,本文提出了包含非线性时空特性的改进模型,在此基础上简化控制器的结构.首先加入非线性补偿项修正传统分布参数模型;然后采用Karhunen-Loève(K–L)方法提取系统主导空间基函数,实现系统输出的时空变量分离.利用求解得到的时间系数和系统激励,建立系统时域Hammerstein模型,使系统无限维偏微分方程模型转化为时域有限维常微分方程形式,控制器的设计无需考虑空间耦合的影响;最后,利用最小二乘支持向量机结合奇异值分解法辨识模型中的参数.与传统分布参数模型进行仿真和实验结果比较,验证了方法的有效性.
