液态沥青

Aiming at some characteristics of liquid asphaltum as more viscosity, higher temperature and lesser fluidity, the principle of a new type measuring range system with sound-wave for measuring level of material of liquid asphaltum is researched.

针对液态沥青粘度大、温度高、流动性差的特点，对实现其料位检测的一种新型声波测距系统的机理进行了研究。

3Asphalt fractionated by evaporation results from the mixing of light paraffin series generated in the later stage and normal or heavy oils generated in the earlier, resulting in the precipitation of asphalt from liquid oil because of the unstable state.

燕发分馏沥青是指晚期生成的轻质石腊族烃与早期生成的正常原油或稠油相混，造成不稳定状态，造成沥青从液态石油中析出。

Its petroleum asphalt can be burnt to produce coke, which is the fuel source for steelmaking; can be blended with anthracite and liquid asphalt, then used as blast furnace refractory material or as the primary component of electrolyte aluminum anodes, electric steelmaking electrodes, heat exchangers, and for other high temperature resistant uses; and can be used undiluted for paving roads and roofs.

其石油沥青，可以烧死生产焦炭，这是燃料来源，为炼钢；可以结合在一起无烟煤和液态沥青，然后用作高炉耐火材料或作为主要成分的电解质铝阳极，电炉炼钢电极，热交换器，并为其它耐高温用途；可用于纯粹为摊铺路面及屋顶铺平道路。

Firstly, the smashed and sorted nonmetal powder of abandoned circuit boards is heated to 80-120 DEG C and dried for 30-60min and then added to liquid petroleum asphalt to be blended uniformly through high speed shearing, thus obtaining the modified asphalt.

先将经过破碎分选的废弃电路板的非金属粉，加热到80-120℃干燥30-60min后加入到加热到液态的石油沥青中，经高速剪切使其共混均匀，即得改性沥青。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
