This paper examines and compares the profitability of banks in the USA and China. The USA has the largest market-based banking system and the financial system of China is still bank-based. Our analysis indicates that in terms of profitability, banks in China outperformed those in the USA during our study period (2008–2014). Real estate loans had an adverse effect on US bank profitability during the financial crisis and no effect after the crisis but consistently improved the profitability of Chinese banks. Interest margins have no effect on US bank profitability but a consistently positive effect on Chinese banks, confirming that China is a traditional bank-based economy. Interbank loans have a positive and significant effect on Chinese bank profitability, while interbank domestic loans have a negative effect on US bank profitability. Finally, size had a positive effect on US banks after the financial crisis period, confirming the scale economies of large US banks, but a negative effect on Chinese banks, indicating diseconomies of scale.

Novel Ferricenium Tetrafluoroborate Salt as Latent Thermal Cationic Initiator for Curing of epoxy Resins

引用

Chinese Journal of Chemical engineering 2004年第4期12卷 570-573页

作者：王涛王志华刘金萍 College of Science Beijing University of Chemical Technology Beijing 100029 China Institute of Frontier Medical Science Jilin University Changchun 130021 China novel latent thermal initiator ferricenium tetrafluoroborate salt (FcBF4) for cationic polymerization of epoxides is reported. The activities of FcBF4 for different epoxides including bisphenol-A-type epoxy oligomer E44 cycloaliphatic epoxy ERL4221 and glycidylether epoxy GGE were evaluated by differential scanning calorimetry (DSC). The results showed a moderate thermal initiation activity for E44 and GGE at 78℃and 108℃respectively. When adding GGE to E44 the reaction was enhanced. The temperature of thermal degradation of the cured specimens for the system of E44/FcBF4 E44+10%GGE/FcBF4 and E44+10%ERL4221/FcBF4 is higher than 350℃.

本文综述近期(1995-2005)面板协整检验理论。面板协整分析理论最初是基于结构稳定的分析,主要研究成果可以划分为部门独立的协整检验和部门依赖协整检验。同时部门独立的协整检验又是从微观面板即同质面板协整检验发展到异质面板协整检验。最新发展则集中于结构突变的面板整检验。未来研究集中于(1)面板协整检验统计量渐近分布。(2)混合面板的协整检验理论。(3)多参数协整检验理论。

我厂15tVHD/VOD 真空精炼炉投产以后,反映出原设计配入的5P150 1/7蒸汽喷射泵对于VOD 工艺抽气能力不足,直接影响到吹氧期真空度的保持,拉长了精炼时间。特别是 VOD 进行到数十次后,由于泵体积灰,更使该泵抽气能力大大降低,直接威胁 VOD 工艺的正常进行。分析其原因为:1.积灰后泵内壁光洁度变差。
