研究结果表明：渤中28-2南油田群原油及其混合原油均为低硫、低酸、高含蜡、易凝的中质原油；
The studied results indicate that both crude oils and mixed oils in BZ 28-2S oilfield group are medium oil with sweet, low acid, high wax content and high pour point;
根据输油生产的连续性特点以及输送介质具有易凝、易燃、易爆的性质，站内原油管道施工动火必须严格遵循SY5859—93《石油工业企业动火安全规程》。
The implementation of hot work for station crude oil pipeline must be in accordance with the standard of SY5859-93 because the media transported are solidifiable, inflammable, and explosive.
结果表明：FWC的易磨性优于水泥熟料，FWC具有较强的水化能力和较好的胶凝性，可以作为一种水泥混合材料。
The results show that FWC has better grindability, hydration ability and gelling property, and it can be used as a kind of admixture in cement production.
对易感患者应重视预防PE的发生，术后或因病卧床的患者早期活动、预防性抗凝治疗等均可有效地降低PE的发病率。
We should pay more attention to prevent PE, to advise the patients for early physical activity after operation or rest, to take prophylactic anticoagulation.
许多油液中含有蜡性成分，它们在低温时很易结晶，输送介质的凝点应该低于预期的最低作业温度。
Oil contains many elements of wax, they very easily at low temperatures, crystal, transmission medium of condensation point should be lower than the expected minimum operating temperature.
