Recent ICRF coupling experiments on EAST

Recent ion cyclotron resonance frequency(ICRF) coupling experiments for optimizing ICRF heating in high power discharge were performed on EAST. The coupling experiments were focus on antenna phasing and gas puffing, which were performed separately on two ports of the ion cyclotron resonance heating(ICRH) system of EAST. The antenna phasing was performed on the I-port antenna, which consists of four toroidally spaced radiating straps operating in multiple phasing cases; the coupling performance was better under low wave number ∣k_‖∣(ranging from 4.5 to 6.5). By fuelling the plasma from gas injectors, placed as uniformly spaced array from top to bottom at each side limiter of the B-port antenna, which works in dipole phasing, the coupling resistance of the B-port antenna increased obviously.Furthermore, the coupling resistance of the I-port antenna was insensitive to a smaller rate of gas puffing but when the gas injection rate was more than a certain value(1021 s~(-1)), a sharp increase in the coupling resistance of the I-port antenna occurred, which was mainly caused by the toroidal asymmetric boundary density arising from gas puffing. A more specific analysis is given in the paper.

High Power RF Transmitters for ICRF Applications on EAST

An Ion Cyclotron Range of Frequency (ICRF) system with a radio frequency (RF) power of 4×1.5 MW was developed for the Experimental Advanced Superconducting Tokamak (EAST).High RF power transmitters were designed as a part of the research and development (R&D) for an ICRF system with long pulse operation at megawatt levels in a frequency range of 25 MHz to 70 MHz.Studies presented in this paper cover the following parts of the high power transmitter:the three staged high power amplifier,which is composed of a 5kW wideband solid state amplifier,a 100kW tetrode drive stage amplifier and a 1.5MW tetrode final stage amplifier,and the DC high voltage power supply (HVPS).Based on engineering design and static examinations,the RF transmitters were tested using a matched dummy load where an RF output power of 1.5MW was achieved.The transmitters provide 6MW RF power in primary phase and will reach a level up to 12MW after a later upgrade.The transmitters performed successfully in stable operations in EAST and HT-7 devices.Up to 1.8MW of RF power was injected into plasmas in EAST ICRF heating experiments during the 2010 autumn campaign and plasma performance was greatly improved.

智能硬件从市场“爆棚”走向3个“调整”

如果说2015年是智能硬件产业的“爆棚”与无序期,那么2016年就将是智能硬件产业的调整期,与此前相比,智能硬件的产业技术、从业者的营销策略以及资本市场的态度都将出现转变. 2015:痛并快乐着 2015年的智能硬件产业可以说是痛并快乐着,主要表现在3方面:第一,一些采用单品玩法的小企业开始面临业绩增长的“天花板”,原先的“假想”商业模式变现困难,导致“故事难讲”、融资方面难度增加;第二,一些传统实体企业受到创客与智能热潮的影响,也开始纷纷布局或推出智能产品,以其强大的营销网络与研发能力“回击”单品玩法的创业企业;第三,埋单的群体也就是消费者,在经历了2014年与2015年的“智能”产品体验之后,消费观念开始从之前的好奇体验转变为理性考量,消费动力有所下降.     

哲学基本问题的提出是哲学史发展的逻辑必然

哲学基本问题贯穿整个哲学史，古代本体论哲学并没有自觉到思维和存在的关系，近代认识论哲学由于自觉到了思维和存在的关系，因而使哲学基本问题获得了“完全的意义”。马克思主义哲学第一次明确提出并全面论述了思维和存在的关系问题，并在实践基础上实现了二者真正的统一。只有历史地考察哲学基本问题，才能坚持思维和存在的关系问题是哲学的基本问题，才能在实践中坚持唯物主义，反对唯心主义。
