It is a vital problem about how to provide enough employment opportunities and reduce per capita carbon emissions during the process of urbanization in China. The main of this article think "the Zipf-type city system in area "can achieve the goal of "efficiency and low carbine".
Herein, we report a simple method to fabricate patterned organic/inorganic hybrid 1DPCs by top-down assisted photolithography. Versatile colorful pattern with different size and shape can be produced by selectively exposing the 1DPCs under UV light with predesigned photomask directly. The period change, especially the thickness variation of the top polymer layer, is the main reason for the colorful pattern generation. Because of the swelling property of the polymer layers, the pattern color can be modulated by introducing or taking off organic solvents, leading the as-prepared patterned 1DPCs to be effective sensors with high selectivity.

There exists a long-term equilibrium relation among the export and import of high-tech products and economic growth in China.The contribution of high-tech products′ import is larger than that of its export.High-tech products′ export has the advantageous act on its import in Chain.To promote the export of high-tech products,it is necessary to develop high-tech industry products.Valuing the import of high-tech products is beneficial to the speedy development of China's economy.
The persistent problem of sexual assault on college campuses is receiving attention in both the public sphere and state legislatures. Although a considerable body of research examines various aspects of campus sexual assault, such as rates and reporting, scholars have not examined how state characteristics and interstate dynamics influence the policy process related to campus sexual assault. This gap is compounded by an underemphasis on gender in theories of state policy adoption, even as a record number of women serve in state legislatures. Drawing on a data set that captures the introduction and enactment of campus sexual assault legislation between 2007 and 2017, David R. Johnson and Liang Zhang examine in this article how the state policy adoption and diffusion framework explains the introduction and enactment of campus sexual assault policy. The results of their study show that the number of forcible sex offenses at public colleges, the number of female Democrats in state senates, contributions from women’s interest groups, gubernatorial power, Republican influence, and bipartisan sponsorship influence the campus sexual assault policy process, with varying influence across legislative stages. The authors discuss the implications of their findings for researchers interested in policy adoption and gender issues as well as for advocates working on campus sexual assault policy reform.
