慢中子裂變 的英文怎麼說
中文拼音 [mànzhōngzilièbiàn]
慢中子裂變
英文
slow fission-
Uranium fission may be accomplished by either fast or slow neutrons.
鈾的裂變可用快中子或慢中子來完成。Third, other nuclear quanlities ( such as fission caused by slow neutron, odd - even difference of frequency of bandcrossing etc ) were researched briefly, no other than pairing correlation, their results represented a series of odd - even differences
（ 3 ）對原子核的其它性質（如慢中子引起的裂變，帶交叉頻率的奇偶差等）的奇偶差也作了簡要的研究，正是由於對關聯的存在，其他性質也表現出一系列的奇偶差。A failure which results in the loss of capability of a component to perform its intended safety function, and any consequential failures which result from it
一種物質或媒介，用以減慢核裂變所釋放的快中子，將之變為熱中子，以產生更多熱核裂變。A failure which results in the loss of capability of a component to perform its intended safety function ( s ), and any consequential failures which result from it
一種物質或媒介，用以減慢核裂變所釋放的快中子，將之變為熱中子，以產生更多熱核裂變。The research on rotor dynamics takes a new look after introducing the theory of modern nonlinear dynamics. domestic and international scholars did a lot of research effort by the theory of modern nonlinear dynamics, such as bifurcation and chaos behavior on crack rotor system, vibration of oil film, rub - collision rotors, loosening foundation, catastrophe and gradation of rotor trouble. we got many important results, but most of research that focused on single deck rotors with singularity troubles, research coupling troubles of rotor systems is not enough
目前，國內外科技工作者採用非線性理論和方法對轉子系統進行了大量的研究工作，包括轉子系統裂紋故障的分岔與混沌行為及穩定性，轉子系統的油膜震蕩、碰摩、基礎松動的研究，轉子系統故障的慢變過程及突變的研究等，但是目前轉子系統多被簡化為具有某一單一故障的單盤轉子模型，對耦合故障多盤轉子系統的動力學行為和故障機理研究還比較少，而工程實際中的轉子系統模型更為復雜，耦合故障普遍存在。分享友人
