This paper gives a brief introduction of the formation mechanism of sma and the handing property of pavement from the aspects of theory and research. at the same time, this paper also studies the effect of aggregate size on road - related performance in some different grads. except, it also having inspected to use the sbs, the pe and the combination material of sbs and pe to analyze the influence to the function of material road
瀝青瑪蹄脂碎石混合料（ sma ）以其溫度穩定性好、抗滑性能優良、低噪音、使用耐久等優點在公路建設中越來越受到重視，本文對sma組成特點，強度形成機理與路面使用性能從理論和試驗研究角度進行論述，並針對不同級配的瀝青瑪蹄脂碎石混合料，分析了粗、細集料的粒徑變化對其路用性能的影響，同時也考察了用sbs 、 pe 、 sbs和pe復合改性后的瀝青結合料對混合料的路用性能影響。Abstract : the authors discuss roundly source of loose earth fo r impact - deposit debris flow to develop taking pingchuan debris flow, one of the quite typical impact - deposit debris flows in southwest sichuan province ， as an example in this paper. on the basis of detailed investigations in - situ, geotechn ial testing in lab and theory analysis, all results indicate obviously that moder ate and bulky loose earth in giant debris flow situating in southwest sichuan mo untainous area are main institute, whose tribulation are consistent with landform s. loose earth locating in mid - forepart catchment are quite unstable, so often be comes main source of loose earth of debris flow. formation of loose earth is cont rolled principally by geologic and geotechnical environment while human actions is the secondary factor for loose earth to form. in many times, human actions prov ide loose earth through loose earth stability
文摘:本文以極具典型的平川泥石流為例比較全面的分析了沖淤變動型泥石流的物源問題.根據現場調研及室內巖土分析進行的研究成果顯示，川西南高山深谷地區的大型泥石流溝中的鬆散土體以中、粗粒段為主，其分佈與地形密切相關；位於泥石流溝中、前部位的鬆散土體的穩定性最差，是補給泥石流的重要物源；鬆散土體的發育主要受控于地質及巖土環境，人類活動只能影響鬆散土體的穩定性Typical temperature is 800 - 1000 in cvd diamond process, while the high temperature limits its application in optical window and coating such as gaas, zns etc. low temperature can not only make diamond crystal nucleus finer, reduce surface roughness of diamond films and lessen light dispersion, but also eliminate thermal stress
化學氣相沉積金剛石膜過程中，襯底的典型溫度為800 1000 ，這么高的溫度限制了其作為gaas 、 zns等低熔點光學材料窗口和塗層的應用。低溫沉積金剛石膜不僅可以使晶粒細化，降低表面粗糙度，減小光的散射作用，而且可以消除熱應力。But polycrystalline cvd diamond films have rough and non - uniform thickness which can adversely affect their application. furthermore, it is difficulty to machining the cvd diamond thick - film
但是， cvd金剛石膜為多晶材料，表面為雜亂分佈的晶粒的堆積，顯露出明顯的稜角，表面粗糙度大，后續加工比較困難。Based on the chang - yu highway in julin province, this paper focus on gap - graded asphalt mixtures. aggregate grading of the gap - graded hma was designed by means of void design procedure. this paper give out a kind of new gradation of stone matrix asphalt. at the same time, this paper also studies the effect of aggregate size on road - related performance in some different gradings
本文以吉林省長余高速公路為依託，從瀝青混合料的結構形態入手，利用體積法，對骨架密實型級配類型的瀝青混合料的級配進行研究，提出新型的瀝青馬蹄脂級配，並針對不同級配的瀝青馬蹄脂碎石混合料，全面分析了粗，細集料的粒徑變化對其各種路用性能的影響。( 2 ) with the condition of table 4. 2, the average reflectance decreases and the low reflectance vale moves towards shortwave, the influence on the extinction coefficient ( k ) of the films is very little, refractive index has trend of decrease and the thickness of the films decrease when increasing the total gas pressure, and the refractive index fix on a constant value when the total pressure exceeds a certain value. the phase of tio2 change from rutile to anatase and the size of surface grain change from big to small
（ 2 ）隨著總氣壓的增加薄膜的反射低谷向短波方向移動;總氣壓對消光系數k影響不大;隨著總氣壓的增加薄膜的折射率出現了下降的趨勢，但當總氣壓達到一定的量值時折射率的變化趨于穩定;薄膜的厚度隨總氣壓的增加而減少;隨著總氣壓的增加tio2的晶體結構由金紅石相向銳鈦礦相轉變，薄膜的表面的顆粒度大小由粗大變得微小細密。The results indicated that the crystal particles in coatings were mostly rutile, and the size of the rutile was in a micrometer grade. the surface roughness of coatings was different
發現制備的二氧化鈦功能塗層中晶粒尺寸為微米級，晶型主要為金紅石型二氧化鈦，表面粗糙度值大小不一。分享友人
