| | This paper describes some preliminary studies of the preparation of the superconducting Nb3Ge tape by using a high-speed and multilayer continuous CVD process. The Nb3-Ge films were deposited on the Hastelloy B substrate at the tape speed of 15-23 m/hr. by simultaneous hydrogen reduction of NbCL4 and GeCl2 vapor. Sample NbsGe tapes of 2.5mm in width and with the films on each side 5 μm thick has been prepared with A 15 Nb3Ge as the major phase in the deposit. The sample has a T... | | 本文报道了用快速多层沉积的CVD方法连续制备Nb_3Ge超导带的初步研究结果.用H_2还原气态的NbCI_4和GeCI_2,在带速为15—23m/hr·的加热基体(Hastelloy B)上沉积出Nb_3Ge.已制出带宽2.5mm、沉积层每边厚5μm、A15 Nb_3Ge含量占大部份的样品,其T_c(起始)达到21.0K,T_c(中点)为19.0K,在4.2K和4T场强下,I_c和J_c(Nb_3Ge)分别为115A和4.6×10~5A/cm~2.对改进连续CVD法制备实用化Nb_3Ge带的某些工艺问题进行了讨论. | | 文摘来源 | | An apparatus, developed for data playback of Explosion Seismology and composed of a PC/AT microcomputer and some interface cards, can input the signal recorded by analogical or digital registers into computer in the field. Because of the successful solving of a series of technical problems, such as seeking out the signals on the magnetic tape by scanning the diagram on the screen, automatically recognizing and decoding the time pulses, comparing and measuring the clock error and the shot time with a c... | | 1988年底在华南地区连县—港口近400km的测线上,首次使用了中国科学院地球物理研究所研制的人工爆炸地震野外数据处理装置.该装置由AT型微机及必要的接口板和外围装置组成,能在野外条件下把模拟或数字记录仪记录结果以数字数据形式输入计算机,并进行显示、打印、存储等操作.由于成功地解决了诸如磁带信号直接屏幕扫描搜寻,时间信号自动识别、解码,钟差和零时信号屏幕光点比测,采样率随磁带速度自动调节,多通道长时间信号连续存储,数字滤波和再采样,用普通打印机快速打印高分辨率图形等技术问题,我们在野外记录后2—3天内即能绘出全测线120道记录的剖面图,达到了前所未有的高速度. | | 文摘来源 | | The sound quality of the sounder outfit bears on the stability of magnetic tape speed. All but a good many of cassete recorder on the world adopted the electronic circuit of steady speed, which assures stabilization of tape speed.Therefore, it is necessary to research the practical and simple circuit and to develop the function of steady speed. This paper will go through a practical exemplar to points out the simple method of design and calculation of steady speed c... | | 在音响装置中,磁带走速稳定与否直接关系到音质的好坏.目前国内外大多数录音机均采用电子稳速电路来保证带速的稳定,故研究简单,实用的电路,提高稳速指标很有必要. 本文通过一典型实例,提出稳速电路的简便设计计算方法.并通过调试使设计电路的稳速指标达到国家等级标准(转速误差△n<±1.5%,瞬时抖晃率△W<0.3%).所提出的设计计算方法可供设计与维修人员参考. | | 文摘来源 | |   | | << 更多相关文摘 |
