Based on present public system of light raw material MEK toluol unit, a heavyraw material MEK toluol unit with two or three isothermal filtering stages wasdesigned to produce microcrystalline wax and path asphalt concocting componentfrom furol extracting oil simultaneously.

本项目是依托现有轻质酮苯装置的公用系统，新建一套重质酮苯脱油装置，采用两段等温过滤加工轻脱油生产微晶蜡，并兼顾加工劣质裂化原料、糠醛抽出油生产道路沥青调合组分、橡胶填充油及优质催化原料。

It requires upgrading to make it transportable by pipeline and usable by conventional refineries.

沥青要经过提质加工后才能通过管道输送并被常规的炼油厂炼制。

This method is a new and different way compared with the triaxial test.

这是一种全新的、区别于以往三轴试验的测试沥青混合料抗剪性能的方法。

In this paper, varied factors which influenced the synthesis of epoxypropyl trimethyl ammonium chloride by the reaction of epichlorlhydrin with trimethylamine were studied.

研究了由环氧氮丙烷与三甲胺反应合成环氧丙基三甲基氮化铵沥青乳化剂中间体的各种影响因素。

In the island of Trinidad the oil is in the form of asphalt ,a substance used for making roads.

在 trinidad 岛上，油以沥青的形式存在，这是一种用来修路的物质。

Walking barefoot on the asphalt pavement/trotter makes the bottom of your feet callous .

赤脚走在沥青的路上会使你的脚底起老茧。

Walking barefoot on the asphalt pavement/trotter makes the bottom of your feet callous.

Because cars and asphalt roads to make the air full of formaldehyde, carbon monoxide, nitrogen …… at least 200 meters away from the car trunk road be considered safe.

由于汽车和沥青路面，使空气中的甲醛充分，一氧化碳，氮……至少有200米的车距主干道路被认为是安全的。

It is too early to say, for instance, whether the process, so far tried on polyacrylonitrile carbon fibres, will be equally effective on pitch fibres, though Pickering sees no reason why it should not be. It has been tested on cured and uncured material (about 40% of long-fibre pre-impregnated material comprises uncured manufacturing offcuts) and proved successful on both, but it has not yet been tested against samples of sandwich or bonded structure.

也许目前还言之过早，例如，聚丙烯腈碳纤维的回收过程，是否对沥青纤维同样有效，虽然皮克林称，还找不出不可以的理由；另外，对固化/未固化材料（约40％的未固化长纤维预浸渍材料）的分别实验均证明成功，但尚未对夹芯结构或粘结结构样品进行测试。

The load fatigue stress coefficient used in the load stress calculation for the porous concrete as undersurface of the cement concrete pavement were derived.

根据疲劳方程提出了以多孔混凝土作为水泥混凝土路面下面层应力计算的荷载疲劳应力系数，沥青路面基层层底拉应力验算的抗拉强度结构系数，建立了进行路面结构设计的轴载换算模型。

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.
