Terahertz detectors based on superconducting hot electron bolometers

Low noise terahertz(THz)heterodyne detectors based on superconducting niobium nitride(NbN) hot electron bolometers(HEBs)have been studied.The HEB consists of a planar antenna and an NbN bridge connecting across the antenna’s inner terminals on a high-resistivity Si substrate.The double sideband noise temperatures at 4.2 K without corrections have been characterized from 0.65 to 3.1 THz.The excess quantum noise factor β of about 4 has been obtained,which agrees well with the calculated value.Allan variance of the HEB has been measured,and Allan time up to 20 s is obtained using a microwave feedback method.Also,the intermediate frequency gain bandwidth(GBW)was measured using two dierent methods,resulting in same GBW value of about 3.5 GHz.     

热轧锭杆“黑心”问题的探讨

锭杆是纺机中一种数量大、转速高、尖端要求耐磨的杆状零件。用热轧方法生产的锭杆毛坯,在其纵、横截面上经酸蚀后出现了“黑心”问题。本文通过一系列试验和观察证实“黑心”并非疏松,“黑心”的存在也不影响耐磨性。从而否定了由于“黑心”是疏松而需将现行热轧方法改用车削方法生产锭杆毛坯的论点。本章对“黑心”形成的原因作了分析和探讨,认为“黑心”是由于斜轧时各部分变形不均匀,而使不同区域里纤维状组织的纤维变形形式不同所致。     

On the fit of models to covariances and methodology to the Bulletin..

Notes that 7 of the 10 top-cited articles in the Psychological Bulletin deal with methodological topics. One of these is the P. M. Bentler and D. G. Bonett (1980) article on the assessment of fit in covariance structure models. Some context is provided on the popularity of this article. In addition, a citation study of methodology articles appearing in the Bulletin since 1978 was carried out. It verified that publications in design, evaluation, measurement, and statistics continue to be important to psychological research. Some thoughts are offered on the role of the journal in making developments in these areas more accessible to psychologists. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
