To accelerate the widespread of Synchronous Chip Seal and improve the operation quality of Synchronous Chipsealer, key techniques which influence the operation quality is studied detailedly, including the control of distributing quality, the dynamics characteristics of hydraulic system and the spray characteristics of asphalt nozzle of Synchronous Chipsealer.1 The factors which influence Synchronous Chip Seal quality are studied. Fiducial probability of simultaneous distribution density is advised to be used in evaluating the distribution bias and standard deviation of asphalt and aggregates simultaneously, which is more advanced than the single index evaluation method used before.2 The volume efficiency formula of asphalt pump is revised after analyzing the data of volume efficiency with mathematical statistics, which is helpful to match the asphalt spray system and control the flow out of asphalt pump accurately. With equation deduction and experiment, dynamic of hydraulic system used in Synchronous Chipsealer is studied, which lay the theory foundation on improving the stability and efficiency from design and controlling.4 Simulation on hydraulic system used in Synchronous Chipsealer is done with AMESim; the results indicate that multi-circle parallel connected hydraulic system with constant pressure power is better than that with load-sensing pressure power at present, because the latter will oscillate when the multi circles work at the same time. This conclusion has been proved during the debug of Synchronous Chipsealer.5 Asphalt nozzle characteristics, such as flat jet shape, flow distribution, are studied with experiment, the results indicate that cross quality of asphalt distributing is not increased linearly follow the increase of fan overlap level, the best point usually exists between two whole overlap level, asphalt distributing quality is better than±4% at the 2.5 overlap level, meets the superior specified in standard; The distribution quality of Synchronous Chipsealer can be increased by spray asphalt of different flow rang with nozzle of different diameter

为了加快同步碎石封层技术的推广，提高同步碎石封层设备的作业质量，本文对同步碎石封层设备作业质量的影响因素与控制方法、液压系统的动力学特性和沥青喷嘴的喷洒特性等关键技术进行了深入细致的研究：1研究了影响同步碎石封层作业质量的因素，提出了采用联合密度分布置信概率对同步碎石封层中沥青洒布量和碎石撒布量的系统偏差和标准差指标进行综合评价的方法，克服了传统评价方法只能对单一指标进行评价的缺陷；2采用数理统计的方法，研究了沥青泵的容积效率特性，修正了沥青泵容积效率公式，为沥青喷洒系统的匹配和沥青泵出口流量的精确控制提供了依据；采用数理方程推导与试验相结合的方法，研究了同步碎石封层设备液压系统的动力学特性，为从设计和控制的角度提高同步碎石封层设备液压系统的稳定性和效率奠定了理论基础；3运用AMESim软件对采用负载敏感控制和恒压控制的两种同步碎石封层设备液压系统进行仿真，结果表明：负载敏感控制的并联液压系统在多回路同时工作时，由于液压泵排量控制参考压力不稳定，容易引发液压系统振荡，恒压控制的并联液压系统是目前技术条件下比较理想的同步碎石封层设备工作装置驱动方案；该结论亦通过同步碎石封层设备装机试验得到了验证。4采用试验的方法对沥青喷嘴的喷洒特性进行了研究，结果表明：沥青洒布的横向精度并不是随着喷洒扇面重叠度的增加线性增加，其最高点通常出现在二个重叠度之间的"半重叠位置"，"2.5重叠"洒布时，沥青的横向洒布精度≤±4%，可以达到国家相关标准中的优级标准；同步碎石封层设备还可以根据不同洒布量情况下的流量需求，采用不同通径的喷嘴进行喷洒，提高沥青洒布精度。

NOw Morn her rosie steps in th' Eastern Clime Advancing, sow'd the earth with Orient Pearle, When Adam wak't, so customd, for his sleep Was Aerie light, from pure digestion bred, And temperat vapors bland, which th' only sound [ 5 ] Of leaves and fuming rills, Aurora's fan, Lightly dispers'd, and the shrill Matin Song Of Birds on every bough; so much the more His wonder was to find unwak'nd Eve With Tresses discompos'd, and glowing Cheek, [ 10 ] As through unquiet rest: he on his side Leaning half-rais'd, with looks of cordial Love Hung over her enamour'd, and beheld Beautie, which whether waking or asleep, Shot forth peculiar graces; then with voice [ 15 ] Milde, as when Zephyrus on Flora breathes, Her hand soft touching, whisperd thus.

在东方，晨曦移动着她那蔷薇色的脚步，于是大地上撒满了晶莹的彩珠。亚当照惯例在这时醒来，因为他的睡眠像空气一般轻，是由清纯的饮食和雾霭散发而成，一经曙光的拂照，听见树叶的沙沙声和小河水汽升腾的微音，以及枝头鸟儿悦耳的晨歌，便会消散。这时他惊奇地看见睡中的夏娃，云鬓散乱，两颊如火烧发光般，似乎是没有好好地安眠。他支起了半身，斜倚在一边，面露笃爱的神情，俯视她那睡时醒时同样惊世骇俗的美丽。于是他用和风吹拂百花仙子般的温柔声音，轻轻地抚摸她的手，如此向她轻轻私语：醒来吧，我的美人，我的妻子，我最近所得的礼物，上天最好，最后的赐与，常新的欢忭！

Eric is considerate enough to buy a red Elmo doll which can walk and laugh for his one and a half years old nephew and many gifts for his colleagues. He took a Rubix cube and said frankly that he had been playing it when he was a student.

This kind of throwing motion can be used at short distances when a quick spin is needed, but is not very useful for throws longer than a half-turn.

当距离较近，需要较快的转速时，这种情形是有用的，但当投掷距离比半周投掷的合适距离远时，就不那么管用了。

Eighthly,this Chinese need some experiences, if he has no interest in operating Chinese restaurant , and is also lack of the talent in showing up in broadway or potential ability of working in wal street, then he at latest should take part in all kinds of social activities from middle school stage , like becoming leader in the club or sport teams of the school, it is said reagon , whose study is bad as junior bush, attract the attention from the others by this way, then he should join the army, better to stay some time in navy, kater , nixon, kennedy service for navy,however he got a prize or not during the service time, after that,he should take a layer career, he don't expect to earn a lot from this line, instead , learn some skills from the line of everyone trying to cheat others,, then with this ability enter house of representatives or senate , and become a member of them, if can work as a governer ,like nixon , kilter, Clinton or junior bush, then it is natural to go to white house.this is stardand road for the white to become a president, in the society crowded with the white, a Chinese with yellow skin can't separate from the track an half step, then possilbly to be a president.

第八，这位华裔要有一些必要的经历。如果他对经营中餐馆没有兴趣，他又缺少到百老汇亮相的天赋或是到华尔街发展的潜力，那他最迟也要在上中学时就开始积极参与各种各样的社会活动，比如在学校成为一些俱乐部和运动队的领导人之类的。据说学习成绩和小布什有一比的里根就是这样赢得更多人关注的。然后他要进入军队，最好是在海军服役一段时间，卡特、尼克松和肯尼迪都曾在海军服役，肯尼迪最好的战绩是二战时他指挥的鱼雷艇被日本海军击沉。服役时无论能不能拿到勋章，退役后他应该马上谋得一个律师职业。他不应指望在这个行业里挣多少钱，他要在这个尔虞我诈的行业里练就一身进退自如的本领，然后携艺下山进入州或联邦的众议院或参议院，成为一名受人尊敬的州众议员或联邦参议员，中间如果能像尼克松、卡特、克林顿和小布什那样先干几年州长，然后再向白宫进发就更顺理成章了。这几乎是每一个白人总统标准化的成长路径，在一个白人居多的社会里，一个黄皮肤的华裔他不能脱离这样一个即有轨道半步，才有可能问鼎总统宝座。
