顺磁性的

Magnetic fluid is a relatively new functional material. It has some common quality which was well equable , superparamagnetism .

它还是一种比较新型的功能材料，有着一些共同的性质，比如十分稳定、超顺磁性等。

Besides, we can get the relationship between signal and time by Dynamic Susceptibility Contrast-enhanced Magnetic Resonance Imaging technique.

此外，打入顺磁性对比剂的动态血流灌注影像，还可以得讯号与时间上的相关性。

The temperature-dependent magnetic susceptibility curve showed that there was no Curie-Weiss behavior.

测得的磁化率随温度变化曲线表明得到的纳米线具有顺磁性。

In this paper, the research progress of contrast agent was systematically reviewed. The development of paramagnetic contrast agents was discussed. Contents

本文较系统地评述了目前国内外用于肿瘤成像造影剂的研究进展，并讨论了顺磁性造影剂的发展前景。

Thus the products were paramagnetic, and the paramagnetism could be tracked back to the existence of V.

我们认为该顺磁性是产品中存在的V所产生的。

Objective To determine the feasibility of superparamagnetic iron oxide perfusion T2WI for detecting hyperacute cerebral ischemia.

Once delivered to the heart, injected cells are difficult to distinguish from target tissue by MR in vivo.To specifically imaging injected cells in MR, the recent investigation generally using superparamagnetic iron oxid to label MSCs, which should enable serial tracking and quantification of MSC transplantation noninvasively by MR.

由于MR成像无法区分移植细胞和靶组织细胞，为使移植细胞能在MR上特异性显示，目前广泛使用超顺磁性氧化铁(superparamagnetic iron oxid， SPIO)作为负性标记物标记移植细胞，进行MR体外和活体内的成像研究。

In order to expand the application of MRI contrast agent in clinical studies, in this paper the lyophilized SPIO was prepared.

为进一步拓展MRI造影剂在国内的临床应用，本文制备了注射用超顺磁性铁氧体纳米微粒。

The results show that the nano-structured materials were exactly β-manganese dioxides with tetragonal crystal structures and consisted of straight and smooth nanorods with diameters in the range of 50~70 nm and lengths up to several micrometers, and the β-MnO2 displays also superparamagnetism characteristics.

结果表明，纳米粉体产物是直径为50~70nm，长度约为几个微米并具有四方晶体结构的β-MnO2纳米棒，同时产物表现出超顺磁性特征。

Objective To investigate the biological characteristics of superparamagnetic iron oxideslabeled myoblasts in vitro.

目的 研究超顺磁性氧化铁纳米粒子标记成肌细胞方法及其对成肌细胞活性的影响。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
