A dynamic monitoring and identifying system of Fe2O3 series gas sensors for the research of electronic nose is introduced. The system has 6 channels to input 0~2.5V voltage signals, measures system temperature, makes thermoregulation for sensor with hardware and has LCD screen and voice function. The heating circuit using TL494 chip and PWM mode is realized. Offline and online identification is realized. The hardware design is based on 16 bits MSP430F149 microcontroller. The software design for digital acquisition and identification based on Windows operating system is compiled by Visual Basic 6.0. The test results show that friendly interface, simple operation, accurate data, reliability and stability are obtained. The real-time monitoring for all of the sensors in aerometry or identification can be realized by BP ANN.

The complete ORF of Polygonatum roseum agglutinin gene was amplified as a fragment of 550 bp, which was identical with predicted size.

序列分析表明，克隆获得的新疆黄精凝集素(Polygonatum roseum agglutinin， PRA)基因完整的ORF 片段大小为550 bp，编码1条长159 个氨基酸肽链，没有内含子，其中N 端的28 个氨基酸是信号肽。

It enhances remarkably.MRI can make qualitative diagnosis of carverous angiomas.

结论CT表现与其它实体肿瘤比拟无特异性，定性诊断困难；MRI表现呈底向外的哑铃型或类园型长T1长T2信号改变较具特征性，增强表现为很是显著的巩固，对定性具有决定诊断的作用。

The CT resembles in carvenous angiomas has no particularity compared with the other entity tumors.The MRI image of the bottom outivardly of bottle gourd form or similar round and long T1 and long T2 signal changes was the characteristic of carverous angiomas. It enhances remarkably.MRI can make qualitative diagnosis of carverous angiomas.

CT表现与其它实体肿瘤相比无特异性，定性诊断困难；MRI表现呈底向外的哑铃型或类园型长 T1长T2信号改变较具特征性，增强表现为非常显著的强化，对定性具有决定诊断的作用。

It disjoins the data and control data by setting quick and slow channels. It realizes the lookup of changing length and fixed length by using CAM/RAM. The designed vacuum of quene buffer will be calculated by the self-similar traffic. Consequently router realizes the high speed transmitting.

它通过设置快慢通道把数据流和控制信号分开；用CAM／RAM实现基于路由／标签的高速变长／定长查找：同时接口线卡的队列缓冲区的大小要根据自相似流量的特点来确定，从而实现路由器的高速转发。

Results: The imaging features of subcortical arteriosclerotic encephalopathy were peripheral symmetric halo signal on long T1 and long T2 in cornu anterius ventriculi lateralis, cornu posterius verticuli lateralis and pars centralis.

结果：该病的MRI表现为侧脑室前后角及体部周围对称性月晕状长T1长T2信号，临床分析高血压占67％，痴呆占43％，多发性脑梗塞占84％。

After them march gentlemen of the bedchamber, Black Rod, Deputy Garter, Gold Stick, the master of horse, the lord great chamberlain, the earl marshal, the high constable carrying the sword of state, saint Stephen's iron crown, the chalice and bible.

尾随于后的是侍寝官、黑仗侍卫、勋章院副院长、仪仗队队长、主马官、侍从长、纹章局局长，以及手持御剑、圣斯蒂芬铁制王冠、圣爵与《圣经》的侍从武官长。四名司号步兵吹信号。

The long specific DNA probes were synthesized by polymerase chain reaction in the highly specific gene sequences of above 10 bacteria. The species-specific probes synthesized were inoculated on a nitrocellulose filter and hybridized with template DNA labeled with long-arm photosensitive biotin. The signal of hybridization reaction was observed to detect which bacteria infected. The sensitivity and specificity of the method were studied.

在这10种病原菌高度特异的基因序列内利用聚合酶链反应合成上述10种细菌特异的长链DNA探针，并将合成的特异探针固定在硝酸纤维素膜上，与用长臂光敏生物素标记后的模板DNA进行斑点杂交反应，通过观察杂交信号判断存在何种细菌感染，同时研究该方法的敏感性和特异性。2。
