Humidifying treatment in mat surface could shorten a half time when the temperature of core layer reached to water vaporizingtemperature at most.
板坯表面增湿处理，能使其中心层到达水分汽化温度的时间最多缩短约一半。

At proper temperature, vaporizing solvent is a better route of sol gel for the preparation of nanosized tio 2 powder.
适宜温度下将溶剂蒸发是溶胶—凝胶法制备纳米二氧化钛一种较好的胶凝方式。
