基于失效模式与效应分析(failure model and effect analysis,FMEA)构建中药干法制粒贝叶斯(Bayesian network,BN)故障诊断模型,有效控制风险因素,保证颗粒质量。首先运用FMEA辨识中药干法制粒过程的中、高风险作为节点变量建立具有因果关系的BN模型。依据概率论的数学推理方法对该模型进行精确推理及Netica验证,并以颗粒不合格为证据进行反向推理,逐级确定影响颗粒质量最可能的故障原因。该文基于FMEA筛选出的滚轮压力、原料黏性、滚轮间间隙等工艺、处方、设备方面的中、高风险因素构建中药干法制粒的BN故障诊断模型,并根据该模型对中药干法制粒工艺进行故障诊断,得出颗粒质量不合格的前提下各节点的后验概率。该方法可为操作人员迅速排故及做出决策提供有力支持,以提高故障诊断及预测的效率及精度,有较好的应用创新性。

We present X-ray spectral analyses of the low-mass X-ray binary Cir X-1 during X-ray dips, using the Rossi X-ray Timing Explorer （RXTE） data. Each dip was divided into several segments, and the spectrum of each segment was fitted with a three-component blackbody model, in which the first two components are affected by partial covering and the third one is unaffected. A Gaussian emission line is also included in the spectral model to represent the Fe Kα line at - 6.4 keV. The fitted temperatures of the two partially covered components are about 2 keV and 1 keV, while the uncovered component has a temperature of -0.5-0.6 keV. The equivalent blackbody emission radius of the hottest component is the smallest and that of the coolest component is the largest. During the dips the fluxes of the two hot components are linearly correlated, while that of the third component does not show any significant variation. The Fe line flux remains constant, within the errors, during the short dips. However, during the long dips the line flux varies significantly and is positively correlated with the fluxes of the two hot components. These results suggest; （1） that the temperature of the X-ray emitting region decreases with radius, （2） that the Fe Kα line emitting region is close to the hot continuum emitting region, and （3） that the size of the Fe line emitting region is larger than that of the obscuring matter causing the short dips but smaller than the region of that causing the long dips.

Resource theory is applied to quantify the quantum correlation of a bipartite state and a computable measure is proposed. Since this measure is based on quantum coherence, we present another possible physical meaning for quantum correlation, i.e., the minimum quantum coherence achieved under local unitary transformations. This measure satisfies the basic requirements for quantifying quantum cor- relation and coincides with concurrence for pure states. Since no optimization is involved in the final definition, this measure is easy to compute irrespective of the Hilbert space dimension of the bipartite state.
