随着人工智能应用的实时性、隐私性和安全性需求增大,在边缘计算平台上部署高性能的神经网络成为研究热点。由于常见的边缘计算平台在存储、算力、功耗上均存在限制,因此深度神经网络的端侧部署仍然是一个巨大的挑战。目前,克服上述挑战的一个思路是对现有的神经网络压缩以适配设备部署条件。现阶段常用的模型压缩算法有剪枝、量化、知识蒸馏,多种方法优势互补同时联合压缩可实现更好的压缩加速效果,正成为研究的热点。本文首先对常用的模型压缩算法进行简要概述,然后总结了“知识蒸馏+剪枝”、“知识蒸馏+量化”和“剪枝+量化”3种常见的联合压缩算法,重点分析论述了联合压缩的基本思想和方法,最后提出了神经网络压缩联合优化方法未来的重点发展方向。

Based on the particularities of gas outbursts,i.e.,low gas bearing capacity and low gas pressure in the "Three Soft" coal seam in western Henan,we applied the theories of plate tectonics and regional structural evolution to investigate the mechanism of this seam and its impact on the coal seam gas *** investigation revealed that coal and gas outbursts are distributed in a strip in a NW direction,with a number of high-penetration mines scattered towards the south side and low-gas mines largely located on the north *** analyzed the statistics of 38 gas explosions and the rock-coal sturdiness number coefficient f of 167 sampling sites in the region and found the gas outburst mechanism that features a "low indicator outburst phenomenon".The mechanism is characterized by structural coal as its core,a low gas bearing capacity,low gas pressure and sturdiness coefficient f mostly less than *** research results provide a theoretical foundation for effective control of gas disasters.

中药炮制是中药用药的一大特色,炮制方法的不同可以对中药产生不同的作用效果,使其更加符合临床病证需要,充分发挥中药使用价值。炎症性肠病是病因不明,病患率在逐年增加的一种肠道疾病,近年来研究者从中医辨证、辨病、辨体质、等多方面为出发点,探究对炎症性肠病的治疗,取得了进一步的研究进展,中医药在炎症性肠病的治疗方面体现出独特的优势,但中药在用于炎症性疾病的治疗过程中,具有炮制品使用不明确、炮制增效研究缺乏重视等现状。因此,在通过归纳炎症性肠病的病因、治法及已有关于炎症性肠病炮制中药研究中,归纳认为炒制可以迎合炎症性肠病患者脾虚弱的特点,炮制辅料麦麸、灶心土、黄酒、食醋及米泔水等具有提升药效,增强“健脾”功用;中药在炮制后可以提升治疗炎症性肠病药效物质基础含量,达到提高中药治疗炎症性肠病的作用。

The characteristics of adsorption, desorption, and diffusion of gas in tectonic coal are important for the prediction of coal and gas outbursts. Three types of coal samples, of which both metamorphic grade and degree of damage is different, were selected from Tongchun, Qilin, and Pingdingshan mines. Using a series of experiments in an electrostatic field, we analyzed the characteristics of gas adsorption and diffusion in tectonic coal. We found that gas adsorption in coal conforms to the Langmuir equation in an electrostatic field. Both the depth of the adsorption potential well and the coal molecular electroneg- ativity increases under the action of an electrostatic field. A Joule heating effect was caused by changing the coal-gas system conductivity in an electrostatic field. The quantity of gas adsorbed and AP result from competition between the depth of the adsorption potential well, the coal molecular electronegativ- ity, and the Joule heating effect. △P peaks when the three factors control behavior equally. Compared with anthracite, the impact of the electrostatic field on the gas diffusion capacity of middle and high rank coals is greater. Compared with the original coal, the gas adsorption quantity,△P, and the gas diffusion capacity of tectonic coal are greater in an electrostatic field. In addition, the smaller the particle size of tectonic coal, the larger the△P.

关键词： Electrostatic field Tectonic coal Depth of adsorption potential well Joule heating effect Initial velocity of gas diffusion
