An occasional restless night is nothing to worry about, but a continuous lack of zzz's can hamper your immune system's ability to function. 偶尔休息不好没什么好担心的,但是长期缺乏深度睡眠会妨碍免疫系统的正常作用。
Zzz is the country code. zzz是国家代码。
Environmental aspects which do not specifically relate to pulp and paper production such as XXX, YYY, ZZZ are not or only briefly treated. 与纸浆/纸制造没有明确关系的环境因素仅简要介绍或不提及。
Dad: Some extra zzz will re-energize you. 爸爸:多睡一点会让你重获体力。
Comparing ZZZ-1 ventilation meter with imported instrument, all performance and technology indexes were in accordance with the industrial standard. 采用CFO技术研制的ZZZ-1型通风率测试仪与进口仪器进行实验和对比,各项性能指标及技术指标均符合行业的标准要求。
Meanwhile, ZZZ had a negative catalyst effect to the reaction of the coke and CO2. It increased the hot strength of coke. 同时ZZZ对焦炭与CO2的反应有负催化作用,焦炭反应性降低,焦炭热态强度提高。
Different anthracite and non-caking coal amount had different optimal dosage of ZZZ and the effects of modification are various. 无烟煤和不黏煤用量不同,ZZZ的最佳用量和改性效果也不一样。
But with the adding of an appropriate amount of ZZZ, the cohesiveness of blended coal was enhanced, the distribution of pore was improved, the porosity of coke decreased, the thickness of pore wall was improved, and the crackle of pore wall reduced. 但通过添加适量的ZZZ改性后,配合煤的黏结性指数得到提升,焦炭的气孔分布改善,气孔率下降,气孔壁厚度增加、裂纹减少。
