1.Using vibration acceleration data sets of the gearbox, intrinsic mode functions (IMFs) and their power spectrum density(PSD) extracted with EMD and Fourier analystical techniques. Furthermore, the effective gear fault indexes of the IMF and PSD on 216 frequency band (IMFPSD216) based on the 2nd IMF components(IMF2) and its PSD, and the IMF using filter (IMFFLT) based on IMF2 and its filtered statistical signal, are given.
针对齿轮箱振动加速度数据 ,运用 EMD分解技术 ,得到 IMF(Intrinsic Mode Function)模式分量 ,提出了基于 IMF及功率谱 (PSD)的 IMFPSD2 16指标和基于 IMF及滤波统计的 IMFFL T指标 ,并验证了它们的有效性。
2.There were high significant difference between DD (IMF content was 4.9436?.4646), Dd (IMF content was 2.6007?.5084), and dd (IMF content was 2.1604?.9897) genotype (P
DD(IMF含量为4.9436士2.4646)与Dd(IMF含量为2.6007士1 .5084)和dd(IMF含量为2.1604士0.9897)两种基因型的肌内脂肪含量之间的差异极显著(P
3.Through EMD, practical drum level signal is decomposed into a series of IMFs and their spectrum is analyzed. Each IMF component covers specific frequency band. Useful IMFs are selected to reconstruct the true drum level signal without corresponding disturbance.
先用EMD分解水位信号,然后结合频谱分析对各IMF分量的频带能量进行分析,考虑各分量频段包含信号的物理意义,去除主要干扰因素所对应的IMF分量,提取有用的IMF分量重构得到无干扰成分的水位真实趋势信号,使对汽包水位信号的分析不依赖于工况和参数的影响。
4.The second chapter is named by IMF As a Global Regime, explores the globalization and IMF from the angle of global regime.
第二章“作为全球治理机制的国际货币基金组织”。 是从全球治理的角度探讨经济全球化与IMF的关系，即IMF对于全球化进程具有的促进作用。
5.But it had high significant difference between AA (IMF content was 1.9639?.7317) and Aa (IMF content was 2.5510?.7793) genotype (P
在Msp Ⅰ-RFLP位点，大河、大乌和雅南猪各基因型的肌内脂肪含量之间差异不显著(P＞0.05)，DLY猪AA(IMF含量1.9639±0.7317)与Aa基因型(IMF含量2.5510±0.7793)的肌内脂肪含量之间差异极显著(P＜0.01)。
6.Member states of IMF within the Jamaica system are entitled to choose exchange rate arrangements,and to determine and manage the exchange rate of their currencies. But they must comply with the obligation stipulations in the IMF Agreement and not manipulate the exchange rate to gain unfair competitive advantages.
在牙买加体系下IMF的成员国有权选择汇率安排,有权确定和管理其货币汇率,但须遵守《IMF协定》所规定的义务,不得通过操纵汇率取得对其它成员国的不公平竞争优势。
7.(3)H-FABP gene increased IMF content significantly(P Hh>hh,DD
(3)9种基因型对IMF含量的影响,HH>Hh>hh,DD
8.Frequent and large financial crises have been challenging the international monetary fund(IMF) and its functions in recent years and the calls for reforming the IMF have been the subject of mounting voice in international community.
金融危机的频繁发生对于国际货币基金组织及其职能提出了挑战,国际社会对于IMF改革的呼声日益高涨。
9.The results showed that: (1) In male Kazak sheep, the IMF content increased continuously with growing and showed significant difference (P
结果表明:(1)随着日龄的增加,雄性哈萨克羊的IMF含量持续上升,各生长时期差异显著(P0．05)。
10.(4) In male Kazak sheep, the mRNA expression level of H-FABP was highly positively correlated (r=0.737, P<0.01) with IMF content from day 30 to 90, but that of PPARγ was highly negatively correlated (r=-0.835, P<0.01) with IMF content from day 2 to 90.
(4)在哈萨克羊中,H-FABP基因在30～90日龄间的表达量与IMF含量的相关系数为0.737(P<0.01),而PPARγ基因在2-90日龄间的表达量与之的相关系数为-0.835(P<0.01)。
