2伦理学与环境显示文摘罗尔斯顿这类理论家认为,生态科学的最新发现证明了:大自然是一个能主动争取(好词!)平衡、均衡、完整的自动平衡系统,因此我们应当保护、维护、配合、甚至服从、崇拜和热爱大自然。在此,我不想争辩生态科学证明了或没有证明什么。我只提一个问题:我们从这些生态学事实(不论是何种事实)能否推导出伦理学结论。人们能够从“是”推导出“应该”吗?W.F.弗兰克纳 杨通进 1994世界哲学1994,,6:12
3伦理学与环境显示文摘人类在过去的大部分时间里,至少西方世界到目前为止,都认为伦理学只应考虑那些与其他人、我们自己或上帝——即与人有关联的事态或行为,而很少考虑我们与其它动物的关系,更没有去思考人类应如何处理自己与植物、空气、水或无机物的关系问题.但是,人们最近却发现,我们已经、正在和即将对我们周围的非人类存在物所做的一切并不十分令人满意.那么,我们应根据何种伦理学来对此进行评判并用什么道德来调整我们的行为呢?近来,我们频繁地听到一种呼唤“新伦理学”的呼声;我们被告知需要一种对待环境的新道德.但我认为,作为我们生活基础的传统伦理学(至少其中的大部分)仍然是完美适用的.W.F.弗兰克纳 1994世界哲学1994,,5:8
4PRECIPITATION BEHAVIOR OF M_(2)N IN A HIGH-NITROGEN AUSTENITIC STAINLESS STEEL DURING ISOTHERMAL AGING显示文摘The precipitation behavior of M2N and the microstructural evolution in a Cr-Mn austenitic stainless steel with a high nitrogen content of 0.43mass% during isothermal aging has been investigated using optical microscopy(OM),scanning electron microscopy(SEM),and transmission electron microscopy(TEM). The aging treatments have led to the decomposition of nitrogen supersaturated austenitic matrix through discontinuous cellular precipitation. The precipitated cells comprise alternate lamellae of M2N precipitate and austenitic matrix. This kind of precipitate morphology is similar to that of pearlite. However,owing to the non-eutectoidic mechanism of the reaction,the growth characteristic of the cellular precipitates is different from that of pearlite in Fe-C binary alloys. M2N precipitate in the cell possesses a hexagonal crystal structure with the parameters a = 0.4752nm and c = 0.4429nm,and the orientation relationship between the M2N precipitates and austenite determined from the SADP is [0110]M2N∥ [101] γ,[2110]M2N∥ [010] γ.F.

9参数振动系统亚谐共振理论的新结果:退化分叉解显示文摘本文应用Liapunov-schmidt方法和奇异性理论,首次研究了参数激励非线性振动系统亚谐共振情况下的退化分叉解,这里的退化是指在分叉方程(10)中a_1=0时的情况,这种情况工程振动系统中有时会遇到.文中给出了用Liapunov-schmidt方法计算分叉方程系数的简有效的方法,使计算工作量大大减少.奇异性理论的应用,证明了系统在a_1=0的情况下为余三,这时系统呈现出十分复杂、有趣的动力学现象,如图2所示,从而使我们对该类非线性振动统动力学行为有了更深的了解.一般认为,参数振动系统只有当ε>δ时才可能有周期解,但本证明了由于Strutt图顶点的后移,在ε<δ时也可能存在周期解.数值计算表明,本文的理论果有足够的精度.陈予恕 詹凯君 Langford W.F. 1990振动工程学报1990,3,2:3

11EVOLUTION OF MICROSTRUCTURE OF Sn-Ag-Cu LEAD-FREE FLIP CHIP SOLDER JOINTS DURING AGING PROCESS显示文摘Flip chip bonding has become a primary technology that has found application in the chip interconnection process in the electronic manufacturing industry in recent years. The solder joints of the flip chip bonding are small and consist of complicated microstructures such as Sn solution, eutectic mixture, and intermetallic compounds (IMCs), whose mechanical performance is quite different from the original solder bulk. The evolution of microstructure of the flip chip solder joints under thermal aging was analyzed. The results show that with an increase in aging time, coarsening of solder bulk matrix and AuSn4 IMCs occurred within the solder. The IMCs that are formed at the bottom side of the flip chip bond were different from those on the top side during the aging process. (Cu,Ni,Au)6Sn5 were formed at the interfaces of both sides, and large complicated (Au,Ni,Cu)Sn4 IMCs appeared for some time near the bottom interface after aging, but they disappeared again and thus (Cu,Ni,Au)6Sn5 IMC thickness increased considerably. The influence of reflow times during the flip chip bonding (as-bonded condition) on the characteristics of interfacial IMCs was weakened when subjected to the aging process.Y.H. Tian C.Q. Wang W.F.

18Missense mutations of the fibrillin-1 gene in two Chinese patients with severe Marfan syndrome显示文摘To describe two Chinese patients with severe forms of Marfan syndrome and to report findings of mutational analysis of the fibrillin 1 (FBN1) gene Methods Two Chinese patients were studied, one suffering from Marfan syndrome of infantile onset and the other of neonatal onset Their clinical features were described Mutational analysis of the FBN1 gene was performed using polymerase chain reaction (PCR) technique and direct sequencing of exons 23-32, where the mutational hotspots for severe forms of Marfan syndrome are located Results Two missense mutations were successfully identified, a G3037A transition and an A3083T transversion, the latter being an unreported mutation Conclusion Taking advantage of the clustering phenomenon of mutations in severe forms of Marfan syndrome, one can identify FBN1 mutations in these patients by first screening the mutational hotspots, thus reducing the effort that would otherwise be much greater because of the size of theIvan F.M.
