文摘Elastic or plastic bendable organic crystals have attracted increasing attention in the field of crystal engineering.For the application of flexible materials,the applicable temperature range can not be ignored.However,studies on the flexible organic crystals reported so far have not involved the effect of temperature on the mechanical properties of these materials.Here,organic crystals of 9,10-bis(phenylethynyl)anthracene with phase-dependent mechanical properties over wide temperature ranges are reported.
文摘This paper analyzes the impact of income distribution gap on consumption demand from a theoretical view,and draws the conclusion that there is an inverse relationship between income distribution gap and consumption demand.Then,the paper finds that the existing widening income distribution gap in China has a negative impact on consumption demand,but this is not the key factor for the insufficient consumption demand because of the low level of per capital income.At last,it suggests that governments should improve the income level of entire residents and adjust income distribution structure simultaneously.
