This paper studies the effect of the heterogeneity of major shareholders of listed companies in China on the loss reversibility after they occur loss.The empirical results show that in the sample of all the losses listed companies, the extent of loss reversal occurred of non-controlling shareholders of listed companies after loss was significantly higher than the losses listed companies of controlling shareholders, that have dispersed ownership and validity checks and balances to shareholders of listed companies to make proactive in losses after losses, but even larger losses reversed, the losses of state-owned controlling shareholders of listed companies and the loss of other listed companies, the largest shareholder of the loss of state property, the largest shareholder of listed companies and the loss of other property companies listed on the extent of the loss is not significantly reversed.

Studies on astronomical historic archives are very important for understanding and promoting the progress of astronomy and astrophysics. For long-term solar data sets, they are the oldest topics in statistical astrophysics during the last four hundred years. To reveal the complex physical behavior of solar magnetic structures, a relatively novel time series analysis technique is applied here to investigate the multi-scale oscillation modes and the secular trend of yearly solar sunspot areas during the time interval from 1611 to 2005. Based on the empirical mode decomposition technique, the following results are found: 1) the time series of 395-year solar sunspot areas is decomposed into four intrinsic mode functions with different quasi-periodic oscillations, which could be understood four dynamic processes that have different periodic-scales; 2) for the secular trend of solar magnetic activity, the level of the Sun has a rapid decrease from 1611 to 1670, and then the activity level increases during the period of 1670-2005. The analysis results indicate that the utility of the empirical mode decomposition technique for the study of solar historic archives and could provide some very important information on the understanding of solar magnetic activity variations.
