| 1 | A New Kind of Linear NTC Sensitive Ceramics显示文摘The preparation method of a new kind of SnO2-CdO-WO3 linear NTC (negative temperature coefficient) thermal sensitive ceramics was related in this paper. The electron transfer formula of this N type semiconducting ceramics was given. Factors which affect temperature- resistance characteristic curve, such as the composition of the material, heat treatment condition, the speed of the temperature rising, heat preservation time and sintering atmosphere were thoroughly studied and analyzed. | Letters Mengkui WANG Department of Physics, Jinzhou Normal College, Jinzhou 121003, China | 2001 | Journal of Materials Science & Technology2001，17，5： | 4 |
| 2 | Photoinduced Second Harmonic Generation of Bi_2S_3 Microcrystallite Doped Silica Glass显示文摘Silica glasses doped with Bi2S3 microcystallite was prepared by the sol-gel process. Photoinduced second harmonic generation (SHG) was observed in the glass when it was irradiated with intense 1.06 μm and frequency doubled laser beams from a mode-locked Nd: YAG laser. It was found that the signal intensity increased with the irradiating time and approached a saturation gradually. The effect may be explained reasonably by the DC field model. | Letters Hongbing CHEN and Hai ping XIA Institute of Optoelectric Materials, Ningbo University, Ningbo 315211, China Congshan ZHU and Fuxi GAN Shanghai Institute of Optics & Fine Mechanics, Chinese Academy of Sciences, Shanghai 201800, China | 2001 | Journal of Materials Science & Technology2001，17，5： | 2 |
| 3 | Knowledge Processing Method of Fault Diagnosis Expert Systems for Letter Sorting Equipment显示文摘Based on the analysis of fault diagnosis knowledge of letter sorting machine, this paper proposes a processing method by which the fault diagnosis knowledge is divided into exact knowledge, inadequate knowledge and fuzzy knowledge. Then their presenting and implementing form in fault diagnosis expert system is discussed and studied. It is proved that the expert system has good feasibility in the field of the diagnosis of letter sorting machine. | LI Dian sheng SUN Wan jun Biography:\ LI Dian sheng (1966-), instructor of Shijiazhuang Postal College, received MS in Shengyang Polytechnic University, majoring in artificial intelligence, maintenance of letter sorting machine.

| 16 | 从“社会矛盾指数”研究看北京市社会矛盾情况及居民行为倾向的特点——以2015年社会矛盾指数研究为例显示文摘本文以2015年北京市社会矛盾指数研究为例,对北京市社会矛盾情况和居民应对社会矛盾和利益受损时的行为选择特点进行了描述。结合近六年的社会矛盾指数研究情况,我们发现,社会矛盾水平与居民对矛盾的主观认知相关联,政府应关注社会公众的隐性不满,通过对社会矛盾的量化研究,挖掘社会矛盾的深层次原因,有针对性地缓解和解决社会矛盾纠纷。 | Beijing Institute of Letters to Government | 2016 | 信访与社会矛盾问题研究2016，，3： | 1 |
