By introducing indicators such as industrial structure deviation, comparative labor productivity, international comparison of relative labor productivity as well as employment elasticity, the paper further probed into intricate causes for the imbalance between industrial and employment structures in this specific region from a new angle which based on the evolution process analyses of both industrial and employment structures in Liaoning, Jilin and Heilongjiang in Northeast China. The paper also suggested policy measures to strengthen agricultural developments and to facilitate the balance between industrial and employment structures.展开更多

On the basis of summarizing the changes of industrial structure and employment structure in Shandong Province,the coordination between industrial structure and employment structure in Shandong Province was analyzed by using structure deviation degree and coordination coefficient,and some suggestions to promote the coordinated development of industrial structure and employment structure were put forward according to the practical situations of Shandong Province.展开更多

An idler output power of 2.46 W at 3752 nm is achieved with excellent beam quality, and the corresponding pump-to-idler conversion efficiency is 9.6% at room temperature. The idler output power exhibits a peak-to-peak power stability better than 12.7%, and the corresponding standard deviation is better than 3.6% RMS in about 20 min at the maximum output power. Meanwhile, other characteristics of the generated signal and idler laser are studied in detail and not only offered an effective guide in the research of optical parametric processes in the case of a continuous spectrum, but also broadened the range of random fiber laser applications.展开更多
