自动功率计校准系统

宇航计测技术 1984年第3期 92-95页

校准微波功率计所需要的仪器已重新设计成可用计算器控制,并且能在0.5至11毫瓦的11个功率电平上提供0.01到18千兆赫的校准。用这些仪器组成的系统(系统II)可以以每点1.5秒的速度确定校准因子,几乎不需要操作者看管。高度对称的电阻功率分配器用来在整个频率范围内给被测器件和校准用标准提供接近于相等的入射功率。利用校准用标准和射频功率电平控制器,使送入功分器的功率保持在所选择的电平上。被测器件的输出用热敏电阻座或镇流电阻座Hogelarsen双电动势(Two-E.m.F)电桥和数字电压表进行测量。从电压表或被测功率计的IEEE488接口母线的输出可用计算器读出。要使辐射热测量座长期稳定,就需要进行温度控制。利用一对电桥和具有电阻功分器的温度控制器可以对两个辐射热测量座进行交替比较。本文介绍一种自动校准微波功率计、辐射热测量座和其他功率传感器的计算机辅助测量系统,提出了用功分器校准辐射热测量座的理论,讨论了该系统的使用方法。

Objective To investigate the age-long claim by the locales that the food thickener, m. urens seed, has antispermatogenic, hence, antifertility effects in man. methods Eight-week old male Albino rats were used as the mammalian model for this study. They were assigned to four groups of 6 rats each and treatment with the ethanol extract was for a period of 14 d. The treatment regimes were 70 mg/kg, 140 mg/kg, 210 mg/kg and 0 mg/kg BW in groups A, B, C and D, respectively. Extracts were prepared by Soxhlet extraction using 80% ethanol as the extracting solvent. The stock solution was prepared by dissolving 1 g of the paste extract in 10 ml corn oil （vehicle） to make up 100 mg/ml concentration. At the end of the treatment, sperm from the distal caudal epididymis was collected and analyzed for sperm count, sperm motility and sperm morphology. Results Significant reduction was observed in sperm count and sperm motility （P〈0.05）. The mean sperm count for group A was 6.27±0.02×10^6, for group B was 6.16±0.02×10^6 and group C had 6.0±0.0×10^6 sperm cells The control （group D） had a mean sperm count of 6.50±0.09×10^6 which was higher than that of any treated group. Results of the sperm motility test gave the following mean rates for motile sperm cells after treatment： group A, 57.6±% 2.1; group B, 50.0±4.0; group C, 45.0±4.0. The control had the highest mean motility rate of 72.3±2.1. The observed sperm abnormalities included unusual head with large acrosome, looped tailpiece, mid piece with distal droplet, pin head, pyriform head and long *** The anti-spermatogenic effects of the extract on the sperm in the Albino rat may lead to reduction of fertility.

以N-丁基二乙醇胺(nbdeaH)为配体,通过辅助自组装反应和溶剂热法合成两组异金属多核簇合物。其中[mm’(μ-OH)(nbdea)(CHCO)]·meCN(m=Ga,m’=Dy(2),m=Fe,m’=Y(3))与己发表的3d-4f异金属簇合物[FeDy(μ-OH)(nbdea)(CHCO)]·meCN(1)同构,而[mm’(μ-OH)(nbdea)(m-CHCHCO)]·nmeCN(m=Ga,m’=Dy,n=4(5),m=Fe,m’=Y,n=1(6))与己发表的3d-4f异金属簇合物[FeDy(μ-OH)(nbdea)(m-CHCHCO)]·meCN(4)同构。磁性测试表明,在化合物{GaDy}(2)与{GaDy}(5)中,Dy-Dy之间存在反铁磁耦合相互作用,而在化合物{FeY}(3)与{FeY}(6)中,Fe-Fe之间同样也存在反铁磁相互作用。由此可推测,在己发表的化合物{FeDy}(1)与{FeDy}(4)中,Fe-Dy之间应存在铁磁耦合相互作用。簇合物{GaDy}(2)和{GaDy}(5)表现出单分子磁体行为,其中(GaDy)(2)的有效能垒(U)与己知的同构簇合物{FeDy}(1)十分接近。这也是首次在Ga-Dy异金属簇合物中发现单分子磁体的弛豫现象。
