In this Letter, we present a high-speed volumetric imaging system based on structured illumination and an electrically tunable lens（ETL）, where the ETL performs fast axial scanning at hundreds of Hz. In the system,a digital micro-mirror device（DMD） is utilized to rapidly generate structured images at the focal plane in synchronization with the axial scanning unit. The scanning characteristics of the ETL are investigated theoretically and experimentally. Imaging experiments on pollen samples are performed to verify the optical cross-sectioning and fast axial scanning capabilities. The results show that our system can perform fast axial scanning and threedimensional（3D） imaging when paired with a high-speed camera, presenting an economic solution for advanced biological imaging applications.

Gene mapping of a mouse coat mutation has been investigated. First, 100 10-bp random primers were used to amplify DNA, but the mutation could not be located by this method because there were no correlation between the amplified products and coat phenotypes. Second, by using ldh1 , Car2, Mup1 , Pgb1 , Hbb, Es1O, Es1, Mod1, Gdc1 , Ce2, Es3 as genetic markers, linkage test crosses (two-point test) consisting of intercrossing uncovered BALB/c mice (homozygotes) to CBA/N and C57BL/6 mice with normal hair and backcrossing the heterozygotes of the F1 to the uncovered BALB/c mice were made. It was soon evident that the mutation was linked to Es3 on chromosome 11. Furthermore, three-point test was made by using Es3 and D11 Mit8 (a microsatellite DNA) as genetic markers. The result showed that the mutation was linked to Es3 with the percentage recombination of (7.89 ± 2.19) %, and linked to D11Mit8 with the percentage recombination of (26.30 ± 3.57)%. The percentage recombination between Es3 and D11Mit8 was

佛典汉译从东汉到宋朝,历时1218年,翻译佛典5396卷,史称千年译经运动。佛典汉译是中国翻译坚实的根基,是我国翻译凝练特色、形成传统、构建翻译学的关键所在。关于最早的佛典汉译作品,即佛典汉译的开山之作是哪一部?由于时间久远,一些学者看法不一,至今尚未有定论。学界有三种观点:第一种认为《浮屠经》是最早的佛典汉译作品,第二种认为《四十二章经》是最早的佛典汉译作品,第三种认为《明度五十校计经》是最早的佛典汉译作品。那么孰是孰非?哪部作品才是佛典汉译的开山之作?本文主张回归历史,正本清源,通过考证确定最早的佛典汉译作品,即佛典汉译的开山之作。
