This paper deals with the synthesis of ultrafine diamond ( ufd ) under high pressure and high temperatures generated by negative oxygen balance explosive detonation . the mechanism of synthesis ultrafine diamond by detonation standpoint is presented 本文從理論和實驗兩個方面對利用負(fù)氧平衡炸藥爆轟產(chǎn)生的游離碳,在高溫、高壓下相變?yōu)榧{米金剛石( ultrafinediamond簡稱ufd )作了初步探索。
This paper was detailed to introduce the measurement of main exhaust composition from marine diesel engine . at the same time , this paper discusses the computational method to get exhaust mass flow rate by carbon balance method and carbon / oxygen balance method 本文詳細(xì)介紹了船用柴油機排氣中各主要成分的測量方法,同時討論了用碳平衡和碳氧平衡法計算排氣質(zhì)量流量的過程并編寫了相關(guān)的計算程序。
The only method to get nox mass flow rate is to know nox concentration in the exhaust and the exhaust mass flow rate . this paper discusses the computational method to get exhaust mass flow rate by carbon / oxygen balance method . besides the traditional computational method , this paper also demonstrates the possibility of applying bp neural network to predict no , emissions from marine diesel engines 由于大功率船用柴油機本身所固有的體積大、排氣流量大以及測量困難等特點,使得排氣中no _ x的質(zhì)量流量不能直接測量,而只能通過測量no _ x的體積濃度并確定排氣質(zhì)量流量或體積流量,才能推算出排氣中no _ x的質(zhì)量流量。
百科解釋
Oxygen balance (OB, or OB%) is an expression that is used to indicate the degree to which an explosive can be oxidized. If an explosive molecule contains just enough oxygen to form carbon dioxide from carbon, water from hydrogen molecules, all of its sulfur dioxide from sulfur, and all metal oxides from metals with no excess, the molecule is said to have a zero oxygen balance.
