This paper mainly discusses the meaning of the third party evaluation mechanism of China＇ s pension service quality evaluation system, the significance on the establishment of third-party evaluation mechanism of China＇ s pension service quality and ways to establish third-party evaluation mechanism of China＇s pension service quality.展开更多

The gypsum-salt rock is believed to be formed during the earlier deposition in salt lake, while the overlying coccolith shale in saline lake with relatively low salinity. By comparing the lake environment and la- custrine microbial communities between ancient and recent lakes, cyanobacteria are regarded as the main representative of productivity during the formation of gypsum-salt strata series, with the annual productivity of 1500-2000 gC m-2 yr1. Based on the research of ultramicrofossils in the calcareous shale, coccolith is considered as the main contributor to the productivity during the formation of calcareous shale. On the basis of statistic data of sedimentary rates, shale laminations, and coccolith fossils in each lamination, the quantitative value of productivity is calculated, with the annual productivity of 2250 3810 gC m 2 yr-1 （averagely 3120 gC m-2 yr-1）. Statistic data of large amount of pyrite framboids indicate that the lower water col- umn was persistently in sulfidic or anoxic conditions during the deposition of gypsum-salt strata series, but it changed to be dysoxic when the coccolith calcareous shale was deposited. Both of these water conditions are favorable for the preservation of organic matter. It is estimated that the organic carbon burial efficiency of the Lower Paleogene salt lakes and saline lakes of Dongying Depression is about 10%-15%, which is calculated and analyzed using the multi-parameter geobiological model.展开更多
文摘The quality of service for the aged is related to the problem of population aging in China and the quality evaluation is an important link to improve the quality and level of service for the aged. This paper mainly discusses the meaning of the third party evaluation mechanism of China＇ s pension service quality evaluation system, the significance on the establishment of third-party evaluation mechanism of China＇ s pension service quality and ways to establish third-party evaluation mechanism of China＇s pension service quality.
