电阻温度系数

This clearly indicates that the negative value of dρ/dT in CdYb QCs is mainly due to the quasiperiodicity because these QCs are stoichiomeric compounds with a very narrow single phase range. Positive dρ/dT and anomalously large MR reported previously are found to be due to the existence of free Cd in the samples.

这清楚地显示CdYb准晶的负电阻温度系数是由於准周期导致，因为CdYb准晶是一种单一相范围极窄的当量化合物，以前的研究说其具有正的dρ/dT和异常巨大的磁阻是由於样品中含有金属Cd。

The results show that increasing the solids loading of slurry up to 45% allows minimizing deformation of green sheets during drying and sintering process effectively. When the content of monomers in shurry is 2%-4%, and the content of plasticizer in shurry is 3%-6%, green sheets with good strength and flexibility are obtained. The microstructures and the electric characteristics of PTCR chip thermistors were investigated. A five-layer chip PTCR thermistor with room resistance of 0.8 Ω, temperature coefficient of resistance of 13.40%/℃, and ratio of maximum to minimum of resistance larger than 105 is successfully fabricated.
