本文评估了中国科学院大气物理研究所大气科学和地球流体力学数值模拟国家重点实验室(LASG/IAP)新一代耦合气候模式FGOALS_s对亚澳季风和e.SO的模拟。结果表明,FGOALS_s可以模拟出亚澳季风的主要气候态特征。FGOALS_s模拟的e.SO事件振幅为观测值的70%,同时它合理再现了e.SO周期的非规则性。FGOALS_s可以定性模拟出e.SO的主要空间特征。当赤道东太平洋SST升高时,印度洋和西太平洋海表面气压升高,而东太平洋海表面气压降低。FGOALS_s的主要缺陷在于模拟的e.SO峰值多出现在春季和夏季。与e.SO振幅偏小相反,FGOALS_s模拟的亚澳季风年际变率振幅大于观测。但是观测中亚澳季风年际变率与e.SO暖位相的显著负相关关系,在模式中没有得到合理再现,原因部分可归之于耦合模式在e.SO锁相模拟上的缺陷。由于模式模拟的e.SO峰值出现在北半球春季和夏季,Walke.环流异常下沉支移动到西北太平洋,其激发出的异常反气旋位置较之观测要偏东,导致印度季风降水和e. Nio的负相关关系不显著;在北半球冬季,由于模式中的赤道东太平洋SST暖异常较弱,亚澳季风响应也偏弱。此外,由于赤道东太平洋SST异常向西伸展,观测中位于澳洲季风区的辐散中心向西偏移,最终导致模式中澳洲季风降水与e.SO的负相关同样不显著。

Ofte., the.e.planatory powe. of a le.rne. mode. must be.trade. off against mode. pe.formance. In the.case.of pre.ict-ing runaway software.proje.ts, we.show that the.twin goals of high pe.formance.and good e.planatory powe. are.achie.able.afte. applying a varie.y of data mining te.hnique. (discrimination, fe.ture.subse. se.e.tion, rule.cove.ing algorithms). This re.ult is a ne. high wate. mark in pre.icting runaway proje.ts. Me.sure. in te.ms of pre.ision, this ne. mode. is as good as can be.e.pe.te. for our data. Othe. me.hods might out-pe.form our re.ult (e.g. by ge.e.ating a smalle., more.e.plainable.mode.) but no othe. me.hod could out-pe.form the.pre.ision of our le.rne. mode..

着重研究了一种在玻色-爱因斯坦凝聚态(Bose.e.nste.n Conde.sate.Be.)之间产生光学介导纠缠的方案.该方案使用量子非破坏性哈密顿量,并将Be.置于马赫-曾德(Mach-Ze.nde.)构型中.结果表明,通过对光进行测量,可以诱导产生纠缠态.还特别分析了纠缠态在退相干作用下的效应.研究表明,该纠缠态的行为表现对于原子与光的作用时间较为敏感:当相互作用时间T≤1/√N时,该纠缠态相对稳定;当相互作用时间T>1/√N时,该纠缠态则相对脆弱.
