炎症显像是核素影像诊断的重要研究领域,但其中正电子核素标记的药物报道不多。为探索合成一种可特异性在炎症部位浓集、且可鉴别是否为细菌性感染的正电子核素标记的显像剂,我们研究制备了F标记18的Levofloxacin(LVFX)用于炎症显像。标记方法采用经典的Hamacher法(氟离子亲核取代)标记LVFX,放射化学纯大于98%,放射性得率约40%,热原检测为阴性。结果表明标记方法简单迅速,标记物稳定。研究了F-LVFX在正常炎症动物模型内的生物分布以及炎症动物模型的显像。生物分布和显像结果均表明1818F-LVFX在炎症组织内有较高的摄取,炎症组织与正常组织间有显著性差异(P<0.05),该标记物主要通过肾脏和肝脏排泄。研究表明F-LVFX是一种潜在的炎症显像剂。

Recent Advances in Evaluation of Iron Ore for the Sintering ...

第十届中国钢铁年会暨第六届宝钢学术年会

作者： Lu Liming higuchi takahide CSIRO Mineral Resources Steel Research Laboratory JFE Steel Corporation 1 Kokan-cho

With the rapid change in iron ore supplies and composition, steel mills now have to adjust the composition of the ore mixture to the sinter plant more frequently than ever before. Hence, different scales of test methods have been developed to help sinter plants evaluate new ore types and ore blends in order to optimise their ore mixtures. the reactions in the combustion-melting zone of a sintering bed have a great effect not only on the structural formation of sinter cake but also the permeability of the sintering bed. Understanding of the sintering reactions occurring in this zone is therefore particularly important to improve coke combustion and control melting. Progress has been recently made to carry out in-situ studies of sintering reactions. this paper provides an overview of various techniques which have been developed recently in order to evaluate iron ore and improve the understanding of the iron ore sintering process.

Lately, it is required that the bandwidth of PWM （pulse width modulation） power amplifier is extended. For example, it is in application of the testing power supply of a low frequency immunity examination, or a class-D amplifier. In this paper, the authors show that the bandwidth of PWM power amplifier can be controller. this controller is implemented on a DSP （digital can be made wider with this controller. extended by using an approximate 2DOF （2-degree-of-freedom） digital signal processor）. It is demonstrated from experiments that the bandwidth
