unglued

Chemical glue is often used to encapsulate fiber-optic F-P interferometric sensor to fixup the F-P cavity, which is easy to come unglued as aging. A new encapsulation method to melt fiber and quartz glass tube by high-frequency CO_2 laser is put forward.

针对光纤F-P干涉仪（FPI）传感器封装普遍采用的化学胶水粘合方式存在的胶水老化而脱胶的问题，提出一种用高频CO2激光脉冲加热使光纤与石英管永久熔合进行封装的新方法。

Further analysis revealed that the level of bacteria flask concentration and enzyme activity peaked earlier than the level of fermentation, under the conditions described in the sample fermented liquid level reaches the level unglued faster rate.

进一步分析发现摇瓶水平的菌种浓度和酶活要比发酵水平提前到达顶峰，说明在摇瓶水平条件下发酵液产酶活速率较快。

Newly developed PU sole, taking PU as the main raw material and adopting micro porous foaming technology, solves the unglued and broken problems commonly existed in ordinary PU sole.

新研制的聚氨酯鞋底以聚氨酯树脂为主要原料，采用微孔发泡技术，解决了目前国内普通聚氨酯鞋底容易脱胶、断底等问题。
