基于缺陷俘获理论的CCD转移模型及应用

空间天文探测常使用电荷耦合器件(CCD)作为主要探测器,但极端辐射环境会对CCD性能造成影响,进而影响数据获取。为了深入了解此机制对数据获取的影响,文章基于SRH(Schokley-Read-Hall)理论,分别讨论转移过程中缺陷对电荷捕获以及释放作用,并在CCD电极层面基础上建立转移模型,仿真不同情况下缺陷运行原理。使用此模型模拟仿真STP(Single Trap Pumping)时序,分别讨论实际使用过程中时序对数据获取的影响,以及从STP时序数据中提取相关参数的办法,并讨论各参数间的关系。该模型对于理解辐射缺陷对CCD数据转移的影响,仿真STP时序,以及在实际应用中利用STP时序获取CCD缺陷参数有辅助作用。

Verification analysis of self-verifying automata via semi-tensor product of matrices

The semi-tensor product （STP） of matrices was used in the article, as a new matrix analysis tool, to investigate the problem of verification of self-verifying automata （SVA）. SVA is a special variant of finite automata which is essential to nondeterministic communication with a limited number of advice bits. The status, input and output symbols are expressed in vector forms, the dynamic behaviour of SVA is modelled as matrix product is STP. By such algebraic formulation, three an algebraic equation of the states and inputs, in which the necessary and sufficient conditions are presented for the verification problem, by which three algorithms are established to find out all the strings which are accepted, rejected, or unrecognized by a SVA. Testing examples show the correctness of the results.     

Flavor of Cooked, Ground Turkey Patties with Added Sodium Tripolyphosphate as Perceived by Sensory Panels with Differing Phosphate Sensitivity

The flavor of cooked, ground turkey patties, with and without sodium tripolyphosphate, was profiled by two panels. One panel had a lower threshold for STP in ground turkey. Flavor profiles indicated that turkey patties without phosphate had more intense protein, serumy, brothy, and metallic character and less intense turkey and soapy character than the samples with phosphate. Both panels found similar characteristics for turkey with added phosphate, although the characteristics had a slightly different order of appearance. The panel with a lower threshold for STP found a more intense soapy character that tended to linger in the phosphate-treated samples.

Modeling pressure suppression pool hydrodynamics in the ABWR containment

This paper focuses on the assessment of pressure suppression pool hydrodynamics in the advanced boiling water reactor (ABWR) containment under design-basis, loss-of-coolant accident (LOCA) conditions. The paper presents a mechanistic model for predicting various suppression pool hydrodynamics parameters. A phenomena identification and ranking table (PIRT) applicable to the ABWR containment pool hydrodynamics analysis is used as a basis for the development of the model. The highly ranked phenomena are represented by analytic equations or empirical correlations. The best estimate and several sensitivity calculations are performed for the ABWR containment using this model. Results of the sensitivity calculations are also presented that demonstrate the influence of key model parameters and assumptions on the pool hydrodynamics parameters. A comparison of model predictions to the results of the licensing analyses shows reasonable agreement. Comparison of the results of the proposed model to experimental data shows that the model predicted top vent clearance time, the pool swell height, and the bubble breakthrough elevation are within 10% of the data. The predicted pool surface velocity and the liquid slug thickness are within 30% of the measurements, which is considered adequate given the large uncertainties in the experimental measurements.

3种重要的油气资源评价方法及应用对比

"中国石油第四次油气资源评价"和"全球油气资源评价与利用研究"两个中国石油天然气股份有限公司重大专项刚刚启动,要求统一评价方法,实现评价结果与国际接轨。为了项目能够更好地开展,有必要解剖重要的油气资源评价方法,对比它们的应用特点。介绍了简单帕内托分布模型(SP)、左偏右截帕内托分布模型(STP)和对数正态发现过程模型(LDP)的研究进展及各自的特点。提出了有效的关键参数研究方法,即用迭代法确定SP分布模型中的最大油藏、油藏分布形态等关键参数,用最小二乘法求取STP分布模型中的油藏中位数、标准方差和油藏分布形态等关键参数。例举SP分布模型、STP分布模型和LDP模型的应用过程,总结出它们的适用范围,对比它们在预测最大油藏(S)、油藏个数(N)和总资源规模(R)三方面的结果,得出:在勘探程度较高、资料达到模型要求时,STP分布模型预测效果最好;在勘探程度较低、资料较少时,SP分布模型具有优势;LDP模型应用范围较宽,在中高勘探程度地区应用有优势。SP分布模型预测的油藏个数偏多,STP分布模型预测的最大油藏比较合理,LDP模型预测的总资源规模和油藏个数效果较好,预测的最大油藏误差较大。
