Abstract : there are offered many ways how to improve work of a spark plug. but one of the m ost important problems has not been solved yet. this is a thermal mode operation of a spark plug. the ideal spark plug should be instantly heated at the moment of occurrence of a spark and instantly cooled down in expectation of the foll owing electrical pulse. thus it balances between preservation of heat for self ? c leaning from scale and its removal in avoidance self ? ignition. in this article a uthor managed for this time to offer a spark plug with capability “ self ? regula tion ” of heat flux removed from a zone of ignition. essence of the offer is a t ip ， which is transparent for heat flux. it is produced from single crystal of sap phire
文摘:在如何提高火花塞的工作質量方面有多種方法，但是其中最重要的一個問題還沒有得到解決，那就是火花塞工作的熱學模型問題.理想的火花塞應該能在點火的瞬間被立刻加熱，並且在接下來的電脈沖過程中迅速冷卻，由此在熱量的存儲與散發之間取得平衡，以避免自點火.本文力圖展示一種具有自動調節源於點火區域熱流能力的火花塞，其技術的關鍵是頂部絕緣體材料，它是由藍寶石單晶製作，而非傳統的氧化鋁陶瓷Due to good chemical stability and electrical resistivity, high thermal conductivity and mechanical intensity, wide band gap and low thermal expansion coefficient, aln thin films can be applied for insulating chips for semiconductor devices with high power, thermal dissipation lagers for large and super - large scale integrated circuits, insulating layers or passivation layers for semiconductor
超薄鋁膜由於其特殊的的光學性質，在光學多層膜上有廣泛應用。氮化鋁薄膜化學穩定性高、熱傳導率高、機械強度高、電絕緣性能佳、高能隙、熱膨脹系數低，光學特性優良，可以用作大功率的紫外光學器件的散熱材料。Test method for heat release, flame spread and mass loss testing of insulating materials contained in electrical or optical fiber cables when burning in a vertical cable tray configuration
