認為損害應由具有成本分散能力的一方當事人承擔,通過製造危險的企業將其商品的成本中加入其所承擔的損失,而分散給購買其商品的千千萬萬個消費者而達到成本分攤損失的目的;損害責任應由有能力採取注意義務;避免意外事故發生的當事人負責,受害人一般無此能力,相反危險的製造者則有能力避免損害發生;基於公平的觀念,製造危險者往往從危險活動中受益,由其承擔損失是正義的要求;危險責任的成立,也是訴訟上證據保全的要求,即從事異常危險沼動所導致的損害事件,例如炸藥爆炸、大量汽油爆炸以及飛機失事等、意外事故,查常破壞這些事件過程中的證據,使證據滅失,而由原告證,明被告過失顯然不能,因此對被告的高度危險性活動所生損害應負嚴格責任。Flyer initiation ability is evaluated by means of energy characterizing method on the basis of flyer initiation sensitivity device in the laboratory in the paper. and after theoretically calculating, utilizing gross energy in the system subtracting energy every section consuming flyer energy can be calculated finally

他解釋了很多廚房內的問題,為什麼用微波爐烹飪出的魚味鮮色美,而做出的肉卻難以下咽(微波爐只對水分子有加熱的作用,而加熱的程度僅低於沸點:換言之,這是一種用熱水煮的過程,所以烹飪出的魚會多汁,而肉卻味道一般) ;為什麼僅在上菜之前的那一刻才給沙拉添加拌料(因為油會浸入保護蔬菜的薄弱表層,並迫使蔬菜內含有的對光線有折射作用的空氣,這樣蔬菜就具有了最本質的顏色) ;土豆為什麼通過油炸才味道最佳(因為油炸過程中,大量的澱粉與糖份會浮出到土豆的表面) ;以及為什麼給蛋黃醬解凍的最簡便的方法是先把醬倒出來,等內含的油完全分離之後,然後把醬倒回瓶子里,再不停地攪拌。Security was tight across the island as people remembered the 15 indonesians, four australians and one japanese killed in triple suicide bombings last year
