在本實驗條件下，小的電流密度有利於金紅石相的生成，而少量硫酸根離子的引入對生成銳鈦礦相粉體有利，調整電流密度大小和引入硫酸根離子的量，可以得金紅石型和銳鈦礦型的混合混體；研究無定型粉體，銳鈦礦相粉體以及金紅石型粉體隨溫度的粒徑變化情況時發現，粉體在400以前晶粒長大相對緩慢， 400以後晶粒粗化現象嚴重。Some respects of self - compacting high - strength concrete ( schsc ) made of fujian province ' s local material have been studied in this thesis as follows : 1. studies on microstructure of the schsc. three different mixed schsc and one normal high - strength concrete ( nhsc ) were observed by the scanning electron microscope at different sites and different ages of 1 day, 3 days, 7 days, 28 days and 60 days. from the test, the effects due to no vibrating and admixture on the microstructure of schsc were studied
通過四組強度等級相當，分別為普通混凝土、兩組不摻膨脹劑的自密實混凝土（其粉煤灰的摻量不同）和摻有膨脹劑的自密實混凝土，在同一養護齡期的條件下（ 1天、 3天、 7天、 28天和60天） ，分別選擇粗骨料過渡區、細骨料過渡區、水泥石和砂坑作為觀測點，採用sem進行細觀掃描對比實驗，以研究自密實混凝土因免振搗的特性及摻合料對其骨料界面和水泥石結構的影響。The best dosage of dispersant and disperse medium, and the best time of ultrasonic disperse. secondly, the bp neural network process parameters model which describes the relationship between the important process parameters of the preparation of superfine quartz powder and the important evaluate guidelines was built, based on experimentation data. the forecast of the important guidelines was achieved with this model
其次，本文以試驗數據為基礎，基於bp神經網路建立了球磨法制備超細石英粉體的關鍵工藝參數（轉速，時間，裝樣率，料球比）與粉體的關鍵評價指標（中值粒徑，粗端粒徑，均勻性系數）之間多目標多變量的bp網路工藝參數模型，該模型的建立實現了粉石英制備的關鍵指標預測。Firstly, the environment harm of the waste rock is studied ; secondly, we research the physics and mechanics property of the waste rock of the dabagou tunnel and get the physics and mechanics property index of waste rock ; thirdly, after comminuting the waste rock and compounding concrete as coarse aggregate, we make the comparison between it and the songshan stone in the fuxin building market at present, it proves to possess extension application value ; fourthly, on the foundation of it, we utilize waste rock as coarse aggregate to compound high strength concrete, steel fiber high strength concrete, polymer cement concrete, asphalt concrete by uniform design and research their mechanics property index by experiment
首先闡述了排矸石對環境產生的危害，其次對大巴溝隧道排矸石的物理力學性質進行了試驗研究，獲得了排矸石的物理力學性能指標。將排矸石粉碎后，作為粗骨料配製成混凝土，與目前阜新建築市場上所用的松山石子進行比較，證明其具有推廣應用價值。在此基礎上，利用均勻設計法，將排矸石作為粗骨料配製成高強混凝土，鋼纖維高強混凝土，聚合物水泥混凝土，瀝青混凝土，通過試驗測定其力學指標，獲得了各種排矸石混凝土的優化方程和最佳配合比。Otherwise we found from the experiments that the chloride system erodes seriously the equipment, and that the powders from the sulfate system are too large in size. therefore, only the powders from the system containing alcohol, compared with the powders from the system without alcohol, are fleecier and can be collected more easily
水，乙醇，硝酸鎂和硝酸鋁適宜作為合成尖晶石的起始物，因為通過試驗發現氯化物系統對設備的腐蝕性較大；硫酸鹽系統得到的粉末較粗；含有乙醇的系統得到的粉末比沒有乙醇的系統得到的粉末蓬鬆，易收集。A study on synthesis of high - strength coarse - grained di amond with powdered graphite
用粉狀石墨合成粗顆粒高強度金剛石的研究The aggregate used for the longtan hydropower project is crushed from limestone, and the surface of aggregate presents the coated - powder phenomenon easily in the course of transportation
摘要龍灘水電工程使用的粗骨料為石灰巖碎石，在運送過程中骨料表面容易產生裹粉現象。The transition from dried gel to mullite is : amorphpus si - al spinel mullite, and the equal radius of the final powder is 0. 54 m. deposit method is another efficient kind of method to prepare mullite powder, we also prepared mullite powder by this method and compare with sol - gel method. through the result, deposit method not only need relatively high temperature, but also the radius of grain is coarse, and the distribution is wide
沉澱法也是一種制備莫來石粉末的有效方法，在實驗過程中，我們也採用該法制得了莫來石粉末，並和溶膠凝膠法作了比較，結果發現採用沉澱法制備莫來石粉末其沉澱需要更高的熱處理溫度，並且制得粉末的粒徑較粗、粒徑分佈范圍較寬。分享友人
