By getting Lebesgue characteristic of integrable function of Riemann from the definition of Gather zero measure, discussing the relation between almost continuous everywhere and existent of limit, it gets the theory which is from the function integrability to the consecution and from consecution to the limit existence .i.e. the almost limit existence is equal to the almost continuous everywhere in the integrable function of Riemann. It also gets a unified condition which has a wider range than regulated function and comes to the conclusion that the function of bounded variation is the integrable function of Riemann.

The dissertation begins with the investigation of the fruitful research on function of debt governance in developed countries such as UK, US, Japan and Germany, and attempts to fill some important gaps in our understanding of inefficient investment controlling function, bankruptcy threat function and function of creditor's participating in corporate governance; Second, Theoretical and empirical study is done on whether three functions of debt governance can work well in state-owned listed companies. The result shows that so far the function of debt governance can't work well as expected; Third, after examining the special institutional background of China, the dissertation argues, grounded on the research results, that the essential institutional reasons include creditors and debtors being "quasi" market participants, the "quasi-equal" debtor-creditor relationships and the "quasi" market rules; Finally, it comes to the conclusion that the fundamental methods to change the situation are to encourage the supervision of banks, to deepen the reform of state-owned companies and to fulfill the outside institutional requirements for guaranteeing the function of debt governance.
