鄂尔多斯盆地上三叠统延长组碎屑岩沉积是典型低渗透砂岩储集层,岩石成分的准确鉴定和定量分析是储层评价的基础.应用太赫兹时域光谱技术研究了延长组常见单矿物在0.1–1.7 THz的光谱特征及光学参数特征,在傅里叶变换的基础上表明不同单矿物在太赫兹波段的光谱特征差异显著.利用太赫兹光谱技术可以分析岩石中单矿物的含量.在此基础上,分析了延长组沉积岩太赫兹光谱特征及其与主要组分光谱特征间的关系,研究表明沉积岩太赫兹光谱与主要组分光谱之间符合Beer-Lambert定律,沉积岩的太赫兹光谱特征是其各个组分光谱叠

近些年由于大数据的出现,传统的数据库技术在某种程度上难以承担对大数据的查询和储存的需求,人们对数据的查询和存储技术提出了更新和更高的标准。由此在数据库技术的基础之上出现了数据仓库,当人们设计数据仓库时,粒度级别的确定是数据查询和储存的重要因素。目前对粒度级别的确定主要采用的是估算算法,对粒度的估算具有一定的模糊性,在查阅了某些粒度的估算算法和文献之后提出了一种以MMTD算法为主算法的粒度级别估算算

This paper presents an Euler discretized inertial delayed neuron model, and its bifurcation dynamical behaviors are discussed. By using the associated characteristic model, center manifold theorem and
While the significance of oscillator dynamics and coupling structure to synchronization behaviors has been well addressed in the literature, little attention has been paid to the possible influence of
