基于SPM的航空转包生产能力研究

针对国际航空转包对航空制造企业生产能力的要求,分析了航空转包能力的评价构成要素,基于供应商绩效测量标准体系SPM建立了转包能力的模型和转包能力的三维体系结构,并通过三维能力模型的能力分区分层评价对航空企业的转包能力进行分析。该模型及方法能对企业转包能力进行全面评价,发现企业转包生产的能力优势和能力薄弱环节,为企业提高转包能力指明了纠正和完善的方向。

基于内禀属性的扇区复杂性评估

为了定量描述空域扇区的复杂性,引入交通内禀性概念,通过计算扇区内航空器间的逼近时间、侵略函数、关系矩阵、相关度函数,建立扇区的复杂性测度模型；并通过仿真算例,对扇区复杂度影响因素进行了分析.研究结果表明:复杂性值大小反映了扇区内飞机数量及汇聚、分散程度,复杂性值曲线拐点数量反映了扇区交通有序/无序程度,复杂性值曲线突变反映了扇区交通数量变化情况,可为管制员的监视和冲突解脱方案选择提供一定支持.

Atmospheric response to a Hot SST Event in November 2006 as observed by the AIRS instrument

Using Atmospheric Infrared Sounder (AIRS) products of atmospheric temperature and geopotential height, we investigate the atmospheric response to HE0611, which was found and investigated by [Qin, H., Kawamura, H., Sakaida, F., Ando, K. A case study of the tropical Hot Event in November 2006 (HE0611) using a geostationary meteorological satellite and the TAO/TRITON mooring array. J. Geophys. Res. 113, C08045, doi: 10.1029/2007JC004640, 2008]. HE0611 was formed by connecting two very high SST areas, HE0611-East and HE0611-West. The period-mean atmosphere temperatures at levels of 925 and 850 hPa in HE0611-West are higher, by about 0.5 K, than those in WE0611-East while the atmospheric temperatures at middle to high levels (700–300 hPa) are higher in HE0611-East. The period-mean geopotential heights HE0611-East are much lower than those in HE0611-West for the levels from the surface to 400 hPa. The mean geopotential heights from 400 hPa to 200 hPa are higher in HE0611-East. In the middle and high layers over HE0611-West, the atmosphere temperatures gradually decrease from 7th to 17th, and then increase significantly. The increase in HE0611-East starts from 15th November, which is earlier than that of HE0611-West. The geopotential heights in the high layer of both the areas also show corresponding behaviors. The lagged atmospheric response in the western part is confirmed by the correlation analysis. It emerges that the atmospheric response to HE0611 is well organized and associated with deep convention in HE0611-East and subsidence in HE0611-West. These are also consistent with the HE0611 features and evolution revealed by earlier HE studies.     

Mathematical modeling of heat transfer process in a variable domain

In this paper, a brief review and generalization of studies on the heat transfer and heat conduction problem in a variable domain are presented. The equations of the process, where the boundary displacement velocity is the control, are obtained taking into account heat inflow. This article was submitted by the authors in English.

蜀中名士秦天柱

1998年夏天，暑热正浓的日子，我走进好友萧缤在红瓦寺那间有些沧桑的欧式风格的画室，照例是饮点小酒然后挥毫。当时的萧缤正在省诗书画院进修，师从秦天柱。那时我刚从深圳归来不久，对四川的化艺术界并不是太熟悉，第一次见到那般生动空灵的花鸟画，被画面上扑面而来的诗般的意象所打动，时时临写，记忆犹新。后来虽然中断了绘画，仍然很关注先生的作品，时不时在一些报刊和画集中见到那些打动人心灵的画作。遗憾的是一直无缘与这位才华横溢的画家谋面，但其作品自然流露出的恬淡与闲适高雅之气直相伴我走过高原丘陵和平原。
