STUDY ON THE TREATMENT OF INDUSTRIAL WASTEWATER CONTAINING TRIETHYLAMINE WITH POLYMERIC ADSORBENTS

The treatment of the industrial wastewater,in which the concentration of triethylamine (TEN) and CODcr was around 3450mg/L and 22400mg/L respectively,was studied by adsorption of macroporous resins,Results demonstrate that the polymeric adsorbent CHA-111 has excellent effect on the adsorption and desorption of TEN.The concentration of TEN in the effluent is less than 30mg/L,and the removal efficiency of TEN and total CODcr exceed 99% and 95% respectively.The accumulation and resource reuse of TEN can be realized in this process.

Hydrodynamic Evolution of Spherical Fireball in Relativistic Heavy Ion Collisions

Evolution process can be calculated from the relativistic hydrodynamic equation with certain estimated initial conditions about a single spherical fireball here.So one can estimate a kind of initial condition qualitatively with a possible energy density about ε0≈1.9 GeV/fm^3,and to fit the experimental data at thermal freeze-out based on this process.The evolution from a cylindrical fireball is discussed simply.     

Controlling Strong Chaos by an Aperiodic Perturbation in Area Preserving Maps

We demonstrate a method for controlling strong chaos by an aperiodic perturbation in two-dimensional Hamiltonian systems.The method has the advantages that the controlled system remains conservative property and the selection of the perturbation has a considerable diversity.We illustrate this method with two area preserving maps:the non-monotonic twist map which is a mixed system and the perturbed cat map which exhibits hard chaos.Numerical results show that the strong chaos can be effectively controlled into regular motions,and the final states are always quasiperiodic ones.The method is robust against the presence of weak external noise.     

负离子配位多面体生长基元与晶体表面结构（Ⅲ）：多型性晶体表面螺旋结构的形成：碳化硅（SiC） 、石墨（C）、云母[KMg3（A1Si3O10）]（OH,F）2,碘化镉（CdI2）、氯化镉（CdCl2）

本文用负离子配位多面体生长基元理论模型讨论了多型性晶体表面螺旋结构的形成,提出在多型性晶体中配位多面体呈层状分布,配位多面体的面为层的边界,上,下层负离子配位多面体不是镜象对称的,在三方晶系和六方晶系的晶体中是沿晶轴a,b错开,上,下两层负离子配位多面体体呈交叉对应,从而达到稳定平衡。晶轴c与负离子配位多面体高次对称轴平行,配位多面体往界面叠合是绕着c轴转动的,其叠加轨迹为螺旋或同心环结构。从多型性晶体螺旋结构的规律性可以看出,晶体生长基元为负离子配位多面体,由于负离子配位多面体的面与呈现螺旋结构的晶面平行,所以生长速度慢,是一个显露面积大的稳态面。螺旋结构只是在该面族上显露。     

Yb：YAl3（BO3）4晶体形貌与生长速度的关系

观察测量了不同生长速度（相应于不同降温速度）自发成核生成的Yb:YAl3(BO3)4晶体形貌。粒试较大（＞2mm)的晶体不管降温速率快慢形态都很简单,只发育六方柱（1120）和菱面体（1011）,粒度较小（＜2mm)的晶体形态随降温速率增快而变复杂,发育一些罕见的高指数晶面,说明在生长速率较快的条件下,在晶体生长早期,一些高能面发育,在晶体生长后期已尖灭了,晶体生长的大部分时间是在低能面（1120）和（1011）上进行的,对比了不同生长条件下晶面的粗糙度,随着降温速度的增快,六方柱面（1120）和菱面体面（1011）由光滑变粗糙,顶面（0001）永远是粗糙的,从晶体结构上定性地探讨了3种晶面的杰克逊因子a及生长机理。
