At the long-term of 479 days, the average daily minimum temperature range of three fans is 12.48℃, and the maximum range is 23.07℃.
Firstly, the fiber 1 is hitched by the sleeve of fiber2 and the end of fiber 1 is used to make the Fiber Bragg Grating 3.
The relation is shown as in form (1): (1) Form (1): is temperature coefficient of sensor, is the change of wavelength, is coefficient of thermal expansion of the fiber, is thermo-optical coefficient.

When carbon-coated α-Fe2O3 was galvanostatically cycled at 100 mA g–1 in the voltage range of 3.0–0.005 V, it exhibits a reversible capacity of 479 mAh g–1, assuming about three Li+ ions retrieval.
Fig. 1
After the sevenfold cycling, the reversible capacity was maintained at 479 mAh g–1 with high Coulombic efficiency of 97%, that represents a good cycling stability of electrode.
In particular, sevenfold galvanostatic cycling at 100 mA g–1 of α-Fe2O3/carbon electrode shows a high reversible capacity of 479 mAh g–1.

The modulations on their volumes have been obtained continuously in the wide temperature range of 50-479 oC.
Results and Discussion Fig. 1 XRD patterns of NBT and NBTLC1-3 ceramics.
From Fig. 3, peaks of resistivity at 479 oC, 247 oC and 167 oC are formed in NBTLC1-3 with more content of (LiCe) addition.
In NBTLC1, the peak of NBT at 210 oC is covered up, and that at 507 oC is enhanced as the one at 479 oC, both by the grain boundary effect with Ce and Li-contained phase.
