Standing settling

The experimental research on applying rebound and ultrasonic to assess compressive strength of concrete subjected to fire and considered standing time effect after fire;

应用回弹超声方法评定火灾高温静置混凝土抗压强度的试验研究

The solution containingdifferent particle sizes was allowed standing for 10min or sonicating by speacified power and time, then examined the particlecount of the particle sizes of ≥5μm, ≥10μm, ≥15μm, ≥20μm, ≥25μm and ≥32μm, respectively.

将含有不同微粒的溶液经静置或一定功率、一定时间的超声处理后,以激光注射液微粒分析仪测定各溶液中粒径分别≥5、10、15、20、25、32μm的微粒数量。

Influence of the factors, such as temperature, standing time after cooling of concrete, methods of cooling and curing on the compressive strength of concrete were analyzed.

通过X射线衍射分析及扫描电镜观察,研究了经高温、冷却并静置若干时间后混凝土物相及微观形貌随受火温度、静置时间和冷却及养护方式等的变化情况,探讨了火灾高温静置后混凝土抗压强度变化的原因。

Compared to the nature precipitation method,treated 4h,the light transmittance was 89,the enzymic method was better.

研究自然静置法及酶法对复合食用菌浸提液澄清效果的影响,采用响应面分析木瓜蛋白酶澄清复合食用菌浸提液最优条件,并与自然静置澄清复合食用菌浸提液方法进行对比。

The circumstance of bacteria′s reproduction in disinfected reclaimed water under different preservation conditions and after different static duration were studied from the test,the results showed that: the reproduction speed of the bacteria in the reclaimed water after be disinfected by ultraviolet radiation was slow in the first 6 h,and the bacteria reproduced faster w.

对消毒后中水在不同保存条件下和不同静置时间下细菌增殖情况进行了实验研究,结果表明:紫外线消毒后的中水在最初的6h内细菌增殖缓慢,光照比避光条件下细菌增殖快,因此,紫外线消毒后的中水宜在6h内使用,且配水管网应采用不透光材料。

Circumstances of bacteria reproduction in effluent from ultraviolet sterilizer after different static duration and under different conservative conditions are discussed and analyzed.

本文对紫外线消毒器出水在不同保存方式和不同静置时间后细菌增殖情况进行了分析和讨论。
