It was also found that degradation rate increased obviously in the first phase when poorly soluble EQ was emulsified with Tween-85, but its degradation extent had a little decrease.
结果表明:单酯基季铵盐、双酯基季铵盐和三酯基季铵盐易生物降解,13天后降解度都在90%以上;水溶性不好的双酯季铵盐、混合酯季铵盐及三酯季铵盐用吐温-85乳化后进行生物降解发现,酯基季铵盐前期降解速度明显增加,但降解度都稍有下降。

Degradation curves of APG showed some degradation extent decreased with time.

探讨了结构对降解性的影响 :疏水基的结构对其降解性有较大影响 ,直链醇APG的降解性优于支链醇对APG的降解性 ,碳链较短的降解性优于碳链长的 ,链支化度影响支链醇APG的降解性 ;对其降解曲线的研究表明 :C8~ 1 0 直链、C1 4~ 1 5支链等APG的降解曲线存在降解度随时间下降的特殊现象 ;提出了APG一条可能的降解途径。
2) degradation rate

降解速度
1.
The results showed that n\|alkanes have the fastest degradation rate among petroleum hydrocarbons;heavier n\|alkanes have slower degradation rate;tricosane shares the same degradation rate with the total petroleum hydrocarbons in the soil;the degradation rate of alkanes with carbon number less than 23 is greater than that of t.
结果表明,正构烷烃的降解最为明显;正构烷烃的降解随着碳数的增加其降解速度逐渐减小;其中C23烷的降解速度与石油烃整体降解速度相当,碳数小于23的正构烷烃降解速度大于石油烃降解速度,碳数大于23的正构烷烃降解速度小于石油烃降解速度;C16~C25的正构烷烃在0~6d内降解速度最快,在7~14d内达到最低值,之后有逐渐上升的趋势;整个正构烷烃的降解符合二级反应动力学规律。

In order to know the degradation rate of chlorine dioxide aerosol after indoor air disinfection,instrument analysis method was used to carry out observation on degradation rate of chlorine dioxide after disinfection of rooms of different types.
为了解二氧化氯气溶胶对室内空气消毒后的降解速度,采用仪器分析法,对不同类型房间用二氧化氯消毒后的降解速度进行了试验观察。
3) Size degradation

粒度降解
5) highly degraded

1.
Therefore, how to resolve the identification of special biological samples, such as low copy DNA, highly degraded samples or mixture samples, has been a question that forensic scientists must face to.
但对于高度降解检材应用常规STR技术及现有商品化试剂盒常得不到完整分型或分型失败。
6) degradation temperature

降解温度
补充资料:降解度
分子式:
CAS号:
性质: 即降解(反应)程度。高分子链中每一化学键在某一时间内的断裂几率。通常以α来表示。α=S/(N0-1),式中,N0为聚合物的平均聚合度;S为该聚合物在该反应时间化学键的断裂数。
