Connect EVAP hose near front of tank .

连接油箱前部附近的EVAP软管。

At measured hot spot temperature , the evap - oration rate is theoretically calculated and the relations between emission material storage and lamp life are obtained .

在测定热点温度后，我们计算得了发射材料的损失率和发射材料贮量与寿命的关系。

For the EVAP method , the main shortcoming is the range in the low high too small , it is not benefit to realize the whole wind field structure for lower high layer .

对于EVAP法，主要的一个缺点是低层风场的范围太小，不利于了解系统低层的整体风场结构。

The most important point is that both of them are not appropriative test for desorption capability of EVAP , though we can conclude it by the tests .

最重要的是，它们都不是脱附性检测的专门方法，脱附能力只能由测试结果间接得出。

The paper presents in details the functions , buildups and operating principles of EVAP emission control system , and analyzed the general trouble diagnosis and the test method of double-lane valve .

介绍了本田雅阁轿车EVAP排放物控制系统的作用、组成及工作原理，并着重阐述了EVAP控制系统的常见故障诊断方法及双通阀的检测方法。

Low-temperature micrography technology was applied to the real-time observation of the growth conformation differences of wax crystals in diesel fuel with / without EVAP , and XRD was also performed .

利用低温显微技术对添加降凝剂EVAP前后柴油中蜡的生长形态变化进行了实时观测研究，同时利用x射线衍射技术研究了加剂前后蜡晶微观结构的变化。

The results showed that with the addition of EVAP , the dispersity , integrity and crystallinity of the wax crystals in the diesel fuel were all enhanced greatly the cold flow properties of the diesel fuel were improved .

研究表明，在柴油中添加降凝剂后，蜡的分散度、完整度、结晶度都得到了明显的提高，从而改善了柴油的低温流动性能。

The simulation results suggested that the EVAP showed significant effects on the nucleation and growth of the paraffin crystal when the acetate concentration was around 30 % and there existed one branched methyl group near the acetate group in each block .

在各种乙烯醋酸乙烯丙烯（EVAP）降凝剂中，当EVAP酯含量在30%左右，且在每个链段含有一个靠近酯基的甲基支链时容易在蜡晶的成核和生长过程中发挥作用。
