Modeling Study of Aerosol Indirect Effectson Global Climate with an AGCM

Advances in Atmospheric Sciences 2010年第5期27卷 1064-1077页

Aerosol indirect effects （AIEs） on global climate were quantitatively investigated by introducing aerosol–cloud interaction parameterizations for water stratus clouds into an AGCM （BCC AGCM2.0.1）, which was developed by the National Climate Center of the China Meteorological Administration. The study yielded a global annual mean of -1.14 W m^-2 for the first indirect radiative forcing （IRF）, with an obvious seasonal change. In summer, large forcing mainly occurred in mid to high latitudes of the Northern Hemisphere, whereas in winter, large values were found at 60°S. The second indirect effect led to global annual mean changes in net shortwave flux of -1.03 W m^-2 at the top of the atmosphere （TOA）, which was relatively significant in mid-latitude regions of both hemispheres. The total AIE reduced the global annual means of net shortwave flux at the TOA and of surface temperature by 1.93 W m^-2 and 0.12 K, respectively. Change in surface temperature induced by the total AIE was clearly larger in the Northern Hemisphere （-0.23 K） than in the Southern Hemisphere, where changes were negligible. The interhemispheric asymmetry in surface cooling resulted in significant differences in changes of the interhemispheric annual mean precipitation rate, which could lead to a tendency for the ITCZ to broaden. The total AIE decreased the global annual mean precipitation rate by 0.055 mm df^-1.

《朝鲜时代汉文小说》是韩国当代学者林宪道精选收录的李氏朝鲜时期九篇汉文小说编辑而成的。自古以来,中国的"四书五经"、史传和部分文字、文学作品在朝鲜半岛的流传,不但推动了当地文化的发展,而且对朝鲜(韩国)文学的发展也产生深刻影响。在朝鲜时代的汉文小说中,大量地引录、运用或化用、转用中国古典诗文中的词语、典故是一大特色。本文以林宪道所收录的汉文小说为研究对象,考察其内容、语言等方面对中国古代典籍、诗歌、小说中典故、成语等的运用与借鉴,以此揭示朝鲜时代的汉文小说与中国文化、文学之间的密切联系。

A couple with a proband child of GJB2 （encoding the gap junction protein connexin 26）-associated hearing impairment and a previous pregnancy miscarriage sought for a reproductive solution to bear a healthy child. Our study aimed to develop a cus- tomized preconception-to-neonate care trajectory to fulfill this clinical demand by integrating preimplantation genetic diagno- sis （PGD）, noninvasive prenatal testing （NIPT）, and noninvasive prenatal diagnosis （N1PD） into the strategy. Auditory and ge- netic diagnosis of the proband child was carried out to identify the disease causative mutations. The couple then received in-vitro-fertilization treatment, and eight embryos were obtained for day 5 biopsy. PGD was performed by short-tandem-repeat linkage analysis and Sanger sequencing of GJB2 gene. Transfer of a GJB2c.235delC heterozygous embryo resulted in a sin- gleton pregnancy. At the 13th week of gestation, genomic DNA （gDNA） from the trio family and cell-free DNA （cfDNA） from maternal plasma were obtained for assessment of fetal chromosomal aneuploidy and GJB2 mutations. NIPT and NIPD showed the absence of chromosomal aneuploidy and GJB2-associated disease in the fetus, which was later confirmed by inva- sire procedures and postnatal genetic/auditory diagnosis. This strategy successfully prevented the transmission of hearing im- pairment in the newborn, thus providing a valuable experience in reproductive management of similar cases and potentially other monogenic disorders.

针对高速转子柔片式密封系统,建立了密封区域流场的数学模型,采用一种修正的压力耦合方程组的半隐式方法 (Semi-Implicit Method for Pressure-Linked Equations Revised,SIMPLER)算法和有限差分法对数学模型进行数值求解,构建了柔片式密封性能分析程序,得到密封系统的压力场分布、速度场分布及泄漏量等,研究了不同结构参数和工况参数对密封性能的影响.分析结果表明:泄漏量随密封压差的增大呈线性增长趋势,而随转子转速的增大略有减小;增加柔片宽度、减小柔片长度、减小前/背板-转子间距均对降低密封系统的泄漏量有益,而柔片安装角度的变化则对密封系统的泄漏量影响不明显.基于流场的结果,柔片和转子的动力学响应将被研究.
