試驗結果表明：所選原料的尺寸、形狀及純度可滿足固體潤滑劑的性能要求；聚四氟乙烯樹脂熱分解溫度超過400 ，但在ptfe中加入無機填料會使復合材料吸水率提高，熔融溫度及分解溫度降低，且伴有氧化分解反應；碳纖維表面含有c = o及c - o - c等極性基團，有利於提高其與其它組分的相容性，提高層間剪切強度；均勻設計試驗方法能夠用較少的試驗次數找出配方與摩擦性能間的關系，擬合曲線基本能表示各配方的摩擦系數發展趨勢；配方中不加銅粉或不加石墨，其摩擦系數均較高，說明銅粉和石墨應該配合使用；當銅粉15份、石墨60份時，銅粉30份、石墨30 - 40份時，銅粉60 、石墨15 - 30份時，摩擦系數均具有較低值；純聚四氟乙烯樹脂在空氣冷卻時結晶度最大，磨損量也是三者中最大的；同時，固體潤滑劑試樣在空氣冷卻時的磨損量也是三者中最大的：不論是固體潤滑劑與45 #鋼軸配副或是固體潤滑劑鑲嵌入銅套后與gcr15鋼軸配副，在金屬表面均可形成潤滑轉移膜，從而減少金屬摩擦副表面間的直接接觸，大大延長其使用壽命;轉移膜中主要含有較多的石墨、少量聚四氟乙烯、 moo 。Porcelain stone exploited from a mine is changea into brick - form mud block, through the processes of water - ramming, washing, decontaminating, and depositing. then, the mud bolck is treated with water for farther decontaminating, and is twisted with hand or treaded with feet for squeezing air out of the blocks and for distributing water content well in the block
從礦區採取瓷石，經水碓春細，淘洗，除去雜質，沉澱后製成磚狀的泥塊。然後再用水調和泥塊，去掉渣質，用雙手搓揉，或用腳踩踏，把泥團中的空氣擠壓出來，並使泥中的水分均勻。A meteorological condition characterized by the uniform expansion in volume of a mass of air over a region, usually accompanied by fair dry weather
輻散，散度一種天氣狀況，特徵為：在氣團均勻地散在某一地區上空，常伴有晴朗乾燥天氣In the way based the scientific and tecdrical talks on i presided at and panicipated in, the graduation theis included a p1entful thets in recent years wtll be divided into three parts for depiction conxteniently and clearly, according to the content as fo1lowsf ( l ) the study of shock compression properties with the drixtiir - liquid co and n, experimentally ( 2 ) the study of the phenomenon of excess heat produced by deuteriurn atoms entering into the lattice of titaluxn experimentally ( 3 ) the calcujation for the electronic structure and energy of hydrogen atoms cluster ffi. the mainstream in the first part of the paper is to exposure some experimental tecndques in high pressure and high temperatur shock compression physics, including by using a cryo - target cooled down circulating steaxned n, to condense the well - proportioned mixed liquid sample from pure gas co and n = with equal molar voiurne
