| 2 | A Frequency Determination Method for Digitized NMR Signals显示文摘We present a high precision frequency determination method for digitized NMR FID signals.The method employs high precision numerical integration rather than simple summation as in many other techniques.With no independent knowledge of the other parameters of a NMR FID signal(phaseφ,amplitude A,and transverse relaxation time T_(2))this method can determine the signal frequency f_(0)with a precision of 1/(8π^(2)f_(0)^(2)T_(2)^(2))if the observation time T≫T_(2).The method is especially convenient when the detailed shape of the observed FT NMR spectrum is not well defined.When T2 is+∞and the signal becomes pure sinusoidal,the precision of the method is 3/(2π^(2)f_(0)^(2)T_(2))which is one order more precise than the±1 count error induced precision of a typical frequency counter.Analysis of this method shows that the integration reduces the noise by bandwidth narrowing as in a lock-in amplifier,and no extra signal filters are needed.For a pure sinusoidal signal we find from numerical simulations that the noise-induced error in this method reaches the Cramer-Rao Lower Band(CRLB)on frequency determination.For the damped sinusoidal case of most interest,the noise-induced error is found to be within a factor of 2 of CRLB when the measurement time T is 2 or 3 times larger than T2.We discuss possible improvements for the precision of this method. | H.Yan K.Li R.Khatiwada E.Smith W.M.Snow C.B.Fu P.-H.Chu H.Gao W.Zheng | 2014 | Communications in Computational Physics2014，15，5： | 1 |

| 14 | 纳米链霉素在小鼠结核病模型中治疗作用的研究显示文摘目的对比研究链霉素纳米制剂与普通制剂——硫酸链霉素注射液在小鼠体内经肠胃外给药时的抗结核活性。方法雌性BALB/c小鼠尾静脉感染结核分枝杆菌H37Rv 1×107CFU。感染后第2 d开始按照空白对照组、阳性对照组、比较对照组和纳米链霉素SM-NP BSA组、纳米链霉素SM-NP CRM组的剂量和频率分别腹腔注射给药,给药至感染后28 d。在感染的14、28、56 d分别处死每组4只小鼠进行脾、肺活菌计数。结果SM-NP CRM组在整个实验期间的存活率是100%,SM-NP BSA组第28 d和第56 d的存活率分别为83%和75%。治疗14 d时,比较对照组小鼠脾、肺的菌量较阳性对照组大,而SM-BSA与SM-CRM组小鼠脾、肺的活菌数较阳性对照组降低;治疗4周时,各组的活菌数与2周时相比没有明显变化,但SM-NP BSA与SM-NP CRM组的脾、肺活菌数均比比较对照组低,差异有统计学意义。感染8周时,SM-NP BSA、SM-NP CRM组肺的活菌数量仍比阳性对照组小,差异有统计学意义。结论纳米链霉素制剂SM-NP BSA、SM-NP CRM与普通链霉素注射液相比,在给药剂量与给药频率降低时,在小鼠急性结核病感染模型中表现的抗菌活性仍与阳性对照相当,值得进一步研究。 | 陆宇 赵伟杰 郑梅琴 王彬 M.Weisspapir H.Gao J.Schwarz | 2008 | 中国防痨杂志2008，30，6： | 1 |
