A Study on the Competence Enhancement of Extro-Oriented Enterprise in Our Country——For Example of Compliance Enterprises

内容提要在我国现代化建设的总战略中，外向型经济占有突出的战略地位。改革开放二十多年来，我国企业外向经营、国际化趋势令人瞩目，全国(特别是珠江三角洲、长江三角洲等区域)外向型企业蓬勃兴起。作为外向型经济微观基础的外向型企业，置身国际、国内双重复杂多变的环境，竞争力的提高与否是其生存、发展和竞争成败的关键。外向型企业可定义为：生产过程基本立足于国内，商品交换活动面向国际市场，积极参与国际分工与国际竞争，以出口为导向的出口创汇企业。与企业国际化相比较，两者因参与国际分工的程度差异而导致性质区别，但其界限是相对的。大致而言，外向型企业的外延更为广泛，既包括高级形态的外向经营：即企业国际化，以境外直接投...ABSTRACT Extro-Oriented economy is very important in the modernization construction in our country, and the Extro-Oriented enterprises have taken a more and more important role in the modernization construction in our country. Therefore, How to improve the Extro-Oriented enterprises’ competence not only is necessary to the development for itself, but also is the key to the whole economic develo...学位：管理学硕士院系专业：管理学院企业管理系_企业管理(含财务管理、市场营销、人力资源管理)学号：K2000730

Influence of metal salt on molecular structure of water-soluble rhdium-phosphine complex

The molecular structure of water-soluble phosphine-rhdium complex HRh(CO) . (TPPTS)(3) [TPPTS: P(m-C6H4SO3Na)(3)] affected by the metal salts, e.g., NaCl, NiSO4, CuSO4, Fe-2(SO4)(3) and Cr-2(SO4)(3) was investigated in connection with the biphasic catalysis system by means of high resolution liquid NMR. No evident change in the spectra of P-31(H-1) NMR and H-1 NMR of the water-soluble complex was observed by addition of NaCl and NiSO4. When CuSO4 was added into the complex, however, the peak intensity of H-1 NMR due to H-Rh diminished and accompanied with the gradual disappearance of the phosphorus species of the complex and the appearance of the new-born phosphorus species in the P-31(H-1) NMR spectra. More over, the characteristic twin signals of the complex at delta=44.8, 43.6 in the P-31(H-1) NMR were completely replaced by the new complexes at delta = 28.0-33.4 when Fe-2(SO4)(3) was added. The similar result was obtained in the case of Cr-2(SO4)(3), when higher concentration of Cr-2(SO3)(4) was used. The results obtained shown that a decreasing order of influence of salt on the molecular structure of the complex is: Fe-2(SO4)(3)>Cr-2 (SO3)(4)>CuSO4>>NiSO(4)similar to NaCl

JUNO Sensitivity on Proton Decay p→νˉK+p\to \bar\nu K^+ Searches

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this paper, the potential on searching for proton decay in $p\to \bar\nu K^+$ mode with JUNO is investigated.The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits to suppress the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar\nu K^+$ is 36.9% with a background level of 0.2 events after 10 years of data taking. The estimated sensitivity based on 200 kton-years exposure is $9.6 \times 10^{33}$ years, competitive with the current best limits on the proton lifetime in this channel
