铅锌矿中硫的相态分析

建立了铅锌矿中硫的相态分析的方法,包括自然状态硫、硫酸根态硫和全硫的分析方法。采用非连续浸提的方法用Na2SO3溶液将自然硫浸出,Na2CO3溶液将SO2-4浸出,并分别用碘量法和BaSO4重量法进行测定,总硫以碳硫分析仪定量测定,还原态硫由差减法得到。对选用的铅锌矿中的硫进行了形态分析,通过加标回收考察方法的准确度,各形态硫的加标回收率均在95%左右,符合常量和痕量分析的要求。

Study of low momentum track reconstruction for the BESⅢ main drift chamber

In order to overcome the difficulty brought by the circling charged tracks with transverse momentum less than 120 MeV in the BESⅢ Main Drift Chamber(MDC),a specialized method called TCurlFinder was developed.This tracking method focuses on the charged track reconstruction under 120 MeV and possesses a special mechanism to reject background noise hits.The performance of the package has been carefully checked and tuned by both Monte Carlo data and real data.The study shows that this tracking method could obviously enhance the reconstruction efficiency in the low transverse momentum region,providing physics analysis with more and reliable data.     

Robustness of Cooperation on Highly Clustered Scale-Free Networks

We study the effect of mutation on the evolutionary prisoner＇s dilemma in highly clustered scale-free networks. It is found that cooperation is more sensitive and vulnerable to strategy mutation in more highly clustered networks. For small mutation rates, high clustering coefficient promotes cooperation. For medium mutation rates, high clustering coefficient inhibits the emergence of cooperation. For large mutation rates, cooperation is insensitive to clustering property. We provide explanations for the effects of clustering on cooperation with varied mutation rates.

离子液体增塑生物基聚丁内酰胺的热分解机理

采用疏水性1-丁基-3-甲基咪唑六氟磷酸盐([BMIM]PF₆)和亲水性1-丁基-3-甲基咪唑四氟硼酸盐 ([BMIM]BF₄)两种咪唑类离子液体(IL)增塑聚丁内酰胺(PBL), 探讨了IL对PBL结晶性能及热性能的影响. 研究发现, 两种IL都会削弱PBL分子间氢键, 并抑制PBL晶体在(200)晶面的生长, 降低PBL结晶度. 当IL添加质量分数为5%时, 增塑膜熔点下降7~8 ℃. 与纯PBL膜相比, [BMIM]BF₄增塑PBL膜热稳定性下降, 而[BMIM]PF₆增塑PBL膜的热稳定性提高. [BMIM]PF₆增塑PBL膜热分解过程的热动力学分析结果表明, 其热分解反应活化能为46.68 kJ/mol, 反应级数为1, 热分解最概然机理函数模型符合Mampel单行法则(一级), 即PBL受到热刺激后, 在聚合物和分解产物界面无规律成核, 反应核心具备反应活性, 随后反应逐步扩大, 直至结束.     

Functionalized Hierarchical ZSM-5 Zeolites for the Viscosity Reduction of Heavy Oil at Low Temperature

Herein, we propose a novel approach to reduce the viscosity of heavy oil by functional hierarchical CTMS-ZSM-5-PTMS zeolites. CTMS-ZSM-5-PTMS zeolites synthesized by asymmetric modification and selective alkali etching can reduce the viscosity of heavy oil through adsorbing asphaltenes. This method can reduce the viscosity of heavy oil from hundreds of thousands mPa·s to about ten thousand mPa·s. The work provides an economical and environmentally friendly candidate for heavy oil viscosity reduction under low-temperature conditions.
