Bnormal MRI manifestations in all of the 20 cases with acquired hepatocerebral degeneration,in which T1WI demonstrated increased signal in hibateral lentiform nucleus (n=20),globus pallidus(n=17),surrounding mesencephalon red nucleus(n=15),and in anterior pituitary(n=4)While T2WI demonstrated no corresponding alteration in signal intensityConclusion Abnormal MR signal in the patients with acquired hepatocerebral degeneration has special features and MRI has right value for the diagnosis of this disease

全部病例均有完备的临床与MRI资料。结果：20例脑部均有阳性MRI表现，其中双侧、豆状核20例，苍白球17例，中脑红核周围15例，垂体前叶4例，表现为自旋回波序列T1WI为高信号，T2WI及FLAIR像无异常。结论：获得性肝性脑部变性的MRI征象具有特征性，MRI对该病的诊断有较高价值。

Driving the bimorph cantilever at one of its eigenfrequencies with an appropriate force feedback allows obtaining an effective Q-factor up to 103 in water from its original amount of ～ 40, that is, the sensitivity can be improved.

当双晶片在它的某一本征频率下被激励，通过调节一个适当的反馈力，它的机械谐振品质因数在水中可以从40增强到103，因此成像灵敏度获得显著改善。

In SiGe BiCMOS process, there are a 5.2GHz CMFB micromixer, a 5.7GHz up-conversion micromixer using LC current combiner, a 5.2GHz LC current combine up-converter with lumped element rat-race and a 5.2GHz image rejection double quadrature down-converter.

其中SiGe BiCMOS制程包含了5.2GHz共模回授微混频器电路、5.7GHz 使用LC电流合成器之升频微混频器、整合集总元件Rat-race的5.2GHz LC电流合成升频器与5.2GHz镜像消除双正交四相位降频器等电路。

The size of the diplexer was 18.3mm×15.6mm×0.5mm, at the frequency of 1.87GHz and 2.34GHz, the decay was higher than 55dB, so it suppressed the local oscillator signal and its mage reconstructor tube signal effectively, which met the design of filter with miniaturization. And then the three-dimensional laminated structures were used to realize the design of miniaturization, which was good for the later research.

该双工器尺寸为18.3mm×15.6mm×0.5mm，在频率1.87GHz和2.34GHz处衰减大于55dB，有效的抑制了阻带上的本振信号及其镜像信号，达到了设计指标，并利用三维叠层结构实现了小型化的目的，为以后的工程设计提供了有益的探索。
