论高校网络舆论引导的难点与对策     

张琳 《湖北第二师范学院学报》2011,(7):129-131

高校网络舆论引导是一个新命题,也是新形势下高校宣传思想工作值得深入研究的重大课题,这不单是实践问题,还涉及一系列认识和观念问题。高校网络舆论引导的难点在于容易处于不易控制状态、网络舆论引导的规律难以把握。我们可以从主体阵地的培养,用主流的声音引导舆论;重点加强高校网络舆论引导议程设置;掌握消除网络负面舆论的技巧;完善机制,适时合理配音;增强师生的社会责任、法制、道德意识,以负责任的态度参与网络舆论等方面打开高校网络舆论引导的瓶颈,破解高校网络舆论引导的难题。  相似文献

AHP Comprehensive Evaluation on Sustainable Utilization of Water Resources in Hengshui City,China     

潘峰  赵林 《天津大学学报(英文版)》2015,(2):178-182

In order to investigate the sustainable utilization of water resources in Hengshui City, quantitative analysis and comprehensive evaluation on 15 indexes of Hengshui City, such as the perspectives of social and economic development condition, water resource condition, environment condition, development and utilization of water resources,were conducted by using the analytic hierarchy process(AHP) method from 2004 to 2008. Although the sustainable utilization has been growing from 2004 to 2008, the situation and environment of water resources were not optimistic because of the severe water shortage in Hengshui. In the future, improving the supply capacity is the key target for promoting sustainable utilization of water resources.  相似文献   

Preparation of carbon encapsulated iron nanoparticles with very thin shells by DC arc discharge     

崔屾  张丽爽  崔兰  张帆  林奎  靳凤民  李玲 《天津大学学报(英文版)》2015,21(1):11-18

Carbon encapsulated iron nanoparticles(CEINPs) with very thin shells and good core-shell structures were prepared by DC arc discharge at argon intake temperature(AIT) of 800 ℃. The results of high resolution transmission electron microscope(HRTEM), energy dispersive X-ray(EDX) spectroscope, X-ray diffraction(XRD), and X-ray photoelectron spectroscope(XPS) characterizations on the product B show that the thickness of the carbon shells of CEINPs in the product B is in the range of ca. 0.5—5.3 nm, i. e., which can be as thin as only two layers of graphite. The average diameter of the CEINPs is about 24. 7 nm. The total content of Fe element in the product B is 77.0 wt%. The saturation magnetization(Ms) and coercivity(Hc) of the product B are 107.4 emu/g and 143 Oe, respectively. The formation of the CEINPs in the product B is discussed briefly.  相似文献   

Low-power three-stage amplifier using active-feedback Miller capacitor and serial RC frequency compensation     

张庚宇  肖夏  聂凯明  徐江涛 《天津大学学报(英文版)》2015,21(6):515-523

A low-power three-stage amplifier for driving large capacitive load is proposed. The feedback path formed by the active-feedback Miller capacitor leads to a high frequency complex-pole but a high Q-value, which significantly deteriorates the stability of the amplifier. The serial RC stage introduced as the second stage output load can optimize the resistor Rz and the capacitor Cz under fixed power and small compensation capacitor Ca, which brings about a suitable Q-value of the complex-pole and the gain-bandwidth product extension of the amplifier. The amplifiers were designed and implemented in a standard 65 nm CMOS process with capacitive loads of 500 p F and 2 n F, respectively. The post-layout simulation results show that the amplifier driving the 500 p F capacitive load can achieve a gain of 113 d B, a phase margin of 50.6° and a gain-bandwidth product of 5.22 MHz while consuming 24 μW from a 1.2 V supply. For the 2 n F capacitive load, the amplifier has a gain of 102 d B, a phase margin of 52.8°, a gain-bandwidth product of 4.41 MHz and a power of 43 μW. The total compensation capacitors are equal to 1.13 p F and 1.03 p F. The better figures-of-merits are 108 750 and 205 113(MHz×p F/m W). The layout areas are 0.064 mm×0.026 mm and 0.063 mm×0.027 mm. Compared with the CFCC scheme, the gainbandwidth product is extended by 1.6 times at CL=500 p F and Ca=1.1 p F.  相似文献
