The principle of work is: When ambient temperature rises, the pressure of the SF6 gas increases, drives the indicator along the clockwise rotation, but at the same time, the mouth of the bimetal compensation system "the U shape" publicizes, then impels the indicator to the counter clockwise rotation, when two kind of strength be equilibrium, the ambient temperature change cannot made the indicator deflection.
工作原理是:当环境温度上升时,虽然容器内SF6气体的密度未发生变化但其压力增大,带动指针顺时方向转动,而当温度上升时,双金属补偿装置的"U形"口张大,则推动指针向逆时针方向转动,当两种运动引起表针的偏转量相抵销时,无论环境温度如何变化,指针都不会发生偏转。

This thesis demonstrates the pre-polymers in a polymer-dispersed cholesteric liquid crystals can be polymerized into a polymer film, which can eliminate the aligning capability of the homogeneous alignment layer. Thereafter, the textures of the cholesteric liquid crystals in UV-cured region can be changed from reflective planar texture to the scattered focal conic one. Additionally, the clearing temperature of the liquid crystals can be reduced by doping with chiral dopant or monomers. The cause is the increase of the impurity concentration in LCs. In other words, if the monomers are polymerized, the clearing temperature of LCs in that region should increase due to the decrease of the impurity concentration. Therefore, impurities associated with doping with monomeric and chiral dopants cause the clearing temperature of LCs in cured region to differ from that in uncured region.
本文中,我们提出在高分子聚合物薄膜之胆固醇液晶(polymer-dispersed cholesteric liquid crystals,简称PDCLCs)中,利用紫外光使PDCLC中的单体聚合成薄膜,此即为光引致聚合反应,而该薄膜将原本在表面所作的配向膜覆盖且破坏其配向能力,使胆固醇液晶由原本反射的planar结构转换成散射的focal conic结构;另外,有关液晶材料的相变温度会由於掺杂手性分子或单体而降低,此因液晶材料内『杂质』浓度增加,而造成的液晶材料之不纯度增加,最终导致相变温度降低,若搭配上述光引致聚合反应,则由於光照区之单体聚合,使该区域单体占总材料之比例下降,即不纯度降低,进而使液晶材料之相变温度上升,该区域之相变温度与未照光区有所不同。

From thermal analysis, weight loss occurs pronouncedly at temperatures above 300 oC in air and the residual weight increases with the reaction temperature. The particle size decreases with the increasing ethanol concentration., while the BET surface area decreases when the concentration of water is increased. Pore size measured from the as-synthesized particles is about 2.7 - 4 nm and this becomes slightly smaller after calcination which is about 3 - 5 nm.
TG/DTA中温度上升至约300 oC时,重量开始明显失重,随著合成反应温度上升,最终残留量由1~3%提高为约5~7%,动态光散射粒径分析发现随著乙醇含量增加,煅烧前与煅烧后的粒径尺寸均有下降趋势,随著水含量的增加,比表面积值随著下降,煅烧后的壳层孔隙尺寸约为3~5nm,煅烧前的壳层孔隙尺寸为2.7~4 nm,煅烧后的孔隙度会略为上升。

The P-C-T curves for Ti_(0.17)Zr_(0.08)V_(0.35)- Cr_(0.1)Ni_(0.3) and Ti_(0.17)Zr_(0.08)V_(0.35)Cr_(0.1)Ni_(0.3)Mm_(0.01) alloys have been depicted by electrochemical methods. It is shown that as temperature rises, the hydrogen equilibrium pressure of the alloys goes up, but the hydrogen desorbing performance deteriorates. After addition of Mm, the hydrogen equilibrium pressure of the alloy comes down, and the hydrogen desorbing performance meliorates.

For sample with longer GI time, which resulting in the better uniformity of this sample, the unusual decrease of FWHM is not observed in the measurement of the temperature dependent PL spectra. Considering the better uniformity of the sample, the effect of carrier redistribution on PL spectra is unapparent. Therefore, the FWHM increases gradually with temperature.
对於成长中断时间较长的样品来讲,由於其均匀度较佳,所以在变温的光激光谱量测中,我们并未发现半高宽随温度上升而有下降的趋势,这是因为载子重新分布效应对一个均匀度佳的样品来讲,其显示出来的效果并不明显,所以我们只能观察到电子与声子散射效应所表现出来的现象,也就是半高宽随温度上升而缓慢增加。
