太长

The results suggested that chitinhad a good solubility in the new solvent when its at -30℃and below, but the solubilityof chitin no longer increasesd notable as the temperature reduced; The joined of urea, incertain degree, strengthened the solvency of alkali solvent to chitin. When theconcentration of sodium hydroxide is 8%～12%, Chitin had a good solubility, and theapparent viscosity of chitin solution could up to 4000 mpa·s～5000mpa·s at roomtemperature; In addition,the solubility of chitin in new solvent was high when therefrigerated time was three days and above, but the refrigerated time could not too long,otherwise, the deacetylize degree of chitin got more bigger. The properties of chitin solution were tested by revolving viscosimeter, FT-IR,X-RD and so on.

结果表明，在-30℃及以下甲壳素能很好的溶解于新溶剂中，但甲壳素的溶解度不再随温度的下降而有所增大，而是基本保持不变；尿素的加入，在一定程度上强化了强碱溶剂对甲壳素的溶解，当新溶剂中NaOH浓度为8％～12％时，甲壳素在试验温度下可以获得较好的溶解度，所得溶液在室温下的表观黏度达4000 mpa·s～5000mp·s；冷冻时间为3 d及以上时，有利于甲壳素的溶解，超过3 d，甲壳素的溶解度变化不大，另外，冷冻条件下，甲壳素在强碱溶剂中仍会发生脱乙酰化反应，冷冻时间不宜太长。

Adopt the kind period too long ,also is not fit, because interference can't on time dissolve, make regulate the quality descent.

采样周期太长，也是不合适，因为干扰无法及时消除，使调节品质下降。

I will commence my journey unencumbered with either the weight of unnecessary knowledge or the handicap of meaningless experience.

说实在的，经验确实能教给我们很多东西，只是这需要花费太长的时间。等到人们获得智慧的时候，其价值已随着时间的消逝而减少了。
