2) Duration
[英][dju'reɪʃn] [美][du'reʃən]
段长
1.
Revision of Language Model Based on Duration in Language Verification;

2.
In order to overcome the defects of the duration modeling of homogeneous HMM in speech recognition,a Duration Distribution Based HMM (DDBHMM) is proposed in this paper based on a formalized definition of a left-to-right inhomogeneous Markov model,which has been demonstrated that it can be identically defined by either the state duration or the state transition probabilities.
本文针对齐次HMM语音识别模型在使用段长信息时存在的缺陷 ,形式化地定义了一种适合语音信号描述的自左向右非齐次隐含马尔科夫模型 ,证明了这种模型的状态转移概率表示与状态段长表示的等效性 ,并在此基础上提出了基于段长分布的HMM模型 (DDBHMM ) 。
3.
In order to overcome the defects of the duration modeling of homogeneous hidden Markov model(HMM)in speech recognition and the unrealistic assumption that successive observations are independent and identically distribution within a state,Markov family model(MFM)was proposed.
针对隐马尔可夫(HMM)语音识别模型状态输出独立同分布等与语音实际特性不够协调的假设以及在使用段长信息时存在的缺陷,对隐马尔可夫模型进行改进,提出马尔可夫族模型。
3) long holes
长孔
4) variable perforation density
分段射孔
1.
Based on the knowledge related with the filtration theory and fluid mechanics,the concept of variable perforation density and segmental perforation is proposed in consideration of the coupling of formation fluid with borehole fluid and fiel.
以渗流理论和流体力学相关知识为基础,考虑地层流体和井筒流体的相互耦合作用以及现场的实际需要,提出了变孔密分段射孔的概念,推导出了水平井变孔密分段射孔的井筒压降模型,并分析了孔眼密度变化对水平井井筒压降的影响,为水平井新型完井方式的井筒压降计算提供了理论依据。
5) perforation interval

Determination of perforation intervals and optimal shot density of wells in bottom-water reservoirs with barriers is studied and presented.
研究了带隔板底水油藏油井的射孔井段确定问题,并提出了最佳射开程度的确定方法。
