| 1 | 利用负电阻设计RTD温度传感器应用电路显示文摘在模拟电路设计中,利用往往被人忽略的负电阻,可以简化设计、提高精度、降低成本.比如本文所述用负电阻线性化RTD(Resistance Temperature Detector)温度传感器并去除不期望的互连线寄生电阻.设计一个精确的负电阻并不复杂,可以把一个正电阻放在.一个运放的反馈回路上来精确地构成负电阻.如图1,为得到一个(-R)Ω的负电阻,把一个阻值为RΩ的电阻放在运放输出端至正输入端的反馈回路上,两个10kΩ构成的网络使运放正输入增益维持2V/V.Vin增加1V,则Vout将增加 2V,R上的电流将增加-1(V)/RΩ安培,电路特性等效于一个(一R)Ω的电阻. | R.Mark Stitt David Kunst 孟卫华 | 1996 | 电子技术应用1996，22，8： | 2 |

| 7 | A comparing study of defect generation in IN738LC superalloy fabricated by laser powder bed fusion:Continuous-wave mode versus pulsed-wave mode显示文摘Inconel 738 LC samples were fabricated using laser powder bed fusion under continuous-wave and pulsed-wave modes.Microstructure,surface quality and mechanical properties were compared to evaluate the printing quality between these 2 laser beam modes.The results show that the application of pulsed wave could effectively eliminate cracking in the as-fabricated sample,despite 0.046%porosity generated.Further microstructure analysis revealed that the refinement of grains by the pulsed-wave laser beam was the main contributor in eliminating the cracks.And this refinement was ascribed to the higher cooling rate under the discontinuous radiation of laser beam proofed by the numerical simulation.And the pore formation was related to Rayleigh instability and residual bubbles in the sample under the pulsed-wave mode,while pores were less detrimental to the mechanical properties than cracks.Therefore,the part under the pulsed-wave mode exhibited superior mechanical performance compared to that under the continuous-wave mode. | Chuan Guo Yang Zhou Xinggang Li Xiaogang Hu Zhen Xu Enjie Dong Qiang Zhu R.Mark Ward | 2021 | Journal of Materials Science & Technology2021，，31： | 1 |
