thermo-electric material

Polymers are the most foreground material in integration optical waveguide devices due to small dielectric constant, high electro-optical and thermo-optical constant, low thermal losses, ease of fabrication and vertical integration and so on.

有机聚合物以其介电常数小，电光和热光系数大，热损耗小，易于加工且可垂直集成等优点已成为制作集成光波导器件最具有前景的材料。

Considering the temperature-dependent material parameters, the nonlinear electro-thermo-mechanical coupling is solved by the direct iteration method.

考虑到材料参数的温变特性，用直接迭代法求解电-热-力之间的非线性耦合问题。

Polycrystalline Vanadium Oxides thin films deposited on Si ( 110) and quartz substrates for thermo-sensitive material of uncooled IR detector arrays were fabricated by ion beam sputtering deposition and oxide process.

采用离子束溅射镀膜和氧化工艺在Si（110）和石英衬底上制备了用于非致冷红外探测器阵列热敏材料的混合相氧化钒多晶薄膜。

Also, because thermo-optical and thermal expansion coefficient of the fiber grating and coating material are small, the temperature sensitivity is quite low. Using fiber grating as sensor, the temperature resolution is not so high.

其次，由于光纤光栅及其涂覆层材料的热光系数和热膨胀系数较小，导致光纤光栅的温度灵敏度也较小，如果用光纤光栅作为传感元件，所得到的温度分辨率不高。
