晓观天下·之三十四 真正的“国际秩序修正主义国家”,不在太平洋西岸

正何为"国际修正主义"最近,"修正主义"这个似乎只有老几辈中国人才印象深刻的词重新频繁映入我们眼帘。2017年12月18日特朗普政府提交国会的首份《美国国家安全战略报告》在将中国定性为美国的"战略竞争者""利益挑战者"的同时,也将中国称作"国际秩序的修正主义国家"。在很多中国人的印象中,在对外关系中最激烈使用"修正主义"这个词,还是跟改革开放前那个晦暗年代中发生的中苏论战联系在一起的。     

内墙构造对间断供暖房间热环境的影响

夏热冬冷地区的居民冬季供暖常采用间断供暖方式,运用数值模拟方法,分析内墙构造对间断供暖房间热环境的影响。研究表明:在供暖能耗相同的情况下,内墙构造不同导致室内热环境差异较大;内围护结构的热容量越小,供暖能量利用率越高,其相对于钢筋混凝土内墙的室内操作温度增温效果也越明显。

A new class of variational equation problems

Abstract Applying an analysis method to a group of multivariable equations, a new class of variational equations are proved. Thismethod is more concise and more direct than the others. This result can be applied to some stochastic control models.

Long term monitoring of urban subsidence by Permanent Scatterer DInSAR

When using differential SAR interferometry (DInSAR) to monitor the surface deformation over a long time scale, it is often strongly affected by the spatial and temporal decorrelations and atmospheric dishomogeneities. The recently developed Permanent Scatterers (PS) technique proposed by Fertti et al. can overcome these difficulties by interpreting time-series of interferometric phase only at coherent point scatterers. In this study, we apply this PS technique using 25 ERS-1/2 scenes from 1992 to 2000 to monitor the subsidence in Suzhou. By using the linear deformation model, the deformation map in Suzhou urban area over the eight years is obtained. And the calculated results are in good agreement with the measurements of leveling.
