We analyzed the excited-state structures and emission spectra of firefly emitter, the anionic keto form of firefly oxyluciferin（keto-l）, determined by the time dependent-density functional theory（TD-DFT） approach. The analysis is based on a direct comparison with the highly correlated CASSCF（MS-CASPT2） ab initio approach. 49 DFT functionals were considered and applied to the study. Among the tested functionals, mPW3PBE, B3PW91 and B3P86 give the best performance for ground-state geometry, absorption spectrum, excited-state geometry and emis- sion spectrum.

A pH-responsive polymer Eudragit S-100 has been found to assist in correct folding of FGF-2 （fibroblast growth factor-2） denatured with 8 mol/L urea and 10 mmol/L dithiothreitol at pH 7.2. The refolding of FGF-2 was performed by directly diluting denatured FGF-2 into a refolding buffer containing Eudragit S-100. The ability of Eudragit S-100 to enhance protein refolding level was investigated using MTT method, fluorescence emission spectroscopy and reverse phase HPLC. On the other hand, the result shows the ability of Eudragit S-100 to enhance the refolding level of protein is due to the interaction between Eudragit S-100 and oositivelv charaed FGF-2.

本文旨在分析我国当前新一轮"用工荒"的现状、特征,及其原因,并判断中国是否迎来劳动力供给的"刘易斯转折点"。通过对浙江省345家民营企业、11家人才市场问卷调查,经分析发现:29.7%民营企业面临"用工荒",员工缺口比率为28.5%,小企业"用工荒"现象尤为严重;"用工荒"的实质是"技工荒",初级技工和中级技工最为紧缺;劳动力流动相对收益减少是导致"用工荒"的根本原因,中国正迎来了劳动力供给的刘易斯转折点;要解决"用工荒"问题,民营企业需要提高待遇,改善工作环境,地方政府需要营造良好的就业和服务环境。
