结果表明，无分散剂时，随着乙醇中水的体积分数的增加，乙醇汽油的分层温度逐渐升高；加入主分散剂可以显著降低乙醇汽油的分层温度，而少量助剂B、C可显著改善主分散剂A1的助溶效果；随着分散剂体积分数的增加，乙醇汽油的分层温度逐渐降低；在乙醇体积分数为10%，乙醇中水的体积分数为4.3%，分散剂的体积分数为2.91%，其组成V(A1)∶V∶V为90∶7.5∶2.5时，乙醇汽油的分层温度可达到-25℃。90号汽油的辛烷值调合后提高到93号，且其T10和T50点均较调合前低。

The current research points out that for the CFCHS joints the linear extrapolation method can be used for chords,whereas the quadratic extrapolation method must be used for braces.The hot spot stress distributions on the CFCHS joints tend to be more uniform and their SCFs become smaller significantly,compared with the CHS joints.Axial tension on the brace puts the CFCHS joints at a disadvantage,which produces higher SCFs than axial compression.The effects of nondimensional geometric parameters β,τ and γ on SCFs of the chords of the CFCHS joints are basically the same as those of the CHS joints,but for the braces,there is a bit difference in the effects of parameters β,τ and γ between the two kinds of joints.Concrete has the function of improving the CFCHS joint rigidity and then decreasing SCFs which is expected to increase fatigue strength,but concrete strength grade does not exert significant influence on SCFs.

研究表明：CFCHS节点的热点应力，对主管可采用线性外推方法，对支管需采用二次外推方法；相比CHS节点，CFCHS节点的热点应力分布趋于均匀，SCF显著减小；CFCHS节点支管轴向受拉比受压不利，SCF增大；CFCHS节点几何参数β，τ，γ对主管SCF的影响效应与CHS节点基本一致，但是对支管SCF的影响效应与CHS节点有些差异；混凝土的作用主要是改善CFCHS节点刚度，从而降低SCF，并预期可提高疲劳强度，但混凝土自身强度等级的高低没有显著影响节点的SCF。

同时，制粒的粘合剂在颗粒的分散均匀，改善了压片生产的可压性和胶囊生产的可填性。

The analysis results showed the main causes of reflection cracking of AC overlay on. PCC are the vehicle loading and temperature changes. With the increase of thickness of AC, the affection is not very clear. When the stress-absorbing interlays, which is 2~3cm and low modulus was added in the pavement, the stress in pavement system was reduced obviously.

数值分析结果表明：增加沥青层厚度可减小加铺层内的荷载及温度应力，但效果并不明显，而2～3cm厚的低模量应力吸收夹层的加入可有效地改善整个加铺结构的应力分布，大大降低加铺层底应力集中程度。

This trial test prows that when specific surface remains constant, the output of mill was l0%~15% increased per machine-hour, power consumption reduced 3 kWh/t; when admixture adding rate increased 6%, strength of test samples in each age is equal to that of samples without compound grinding aids added; the initial setting and final setting time are shortened slightly; the workability and fluidity of cement and the grindability of materials are improved remarkably.
