For the long composite cylindrical panels, including the influences of the transverse shear deformation, rotatory inertia and initial geometric imperfections, the nonlinear dynamic equations of the long composite cylindrical panels were derived from Hamilton's philosophy. The nonlinear partial differential equations were transformed to ordinary differential equations by expansion in series and solved numerically by fourthorder Runge-Kutta method.

针对含初始几何缺陷的复合材料圆柱曲板，考虑横向剪切变形、转动惯量、初始几何缺陷以及非扁壳等诸多因素，利用Hamilton原理导出复合材料长圆柱曲板的非线性动力方程；用级数展开把非线性偏微分方程组转化为二阶常微分方程组，并由四阶Runge-Kutta方法数值求解。

The culm length, panicle length, spikelets per panicle and panicle exsertion were evaluated by using F2:3 population including 200 lines, derived from a cross of indica and japonica Milyang23/Jileng1 under five different environments of Beijing (natural normal growing environment), Kunming (natural low temperature condition), Gongzhuling of China and Chuncheon of Korea (natural normal growing environment and cold water irrigation), and QTLs of these traits were analysed by using SSR markers.

以籼粳交密阳23/吉冷1号200个F2：3家系作为作图群体，在北京、昆明、公主岭、韩国春川（正常生长环境和冷水胁迫）等5种不同生长环境下进行了水稻秆长、穗长、穗粒数和穗抽出度等主要农艺性状的异地鉴定，并利用SSR标记进行了上述农艺性状的QTL分析。

By using a DH population derived from a rice indica/japonica cross, genetic analyses of floral characters, such as percentage of exserted stigmas, stigma length, stigma width, style length, anther length, anther width, spikelet length, spikelet width, length-width ratio of spikelet, and panicle exsertion degree, were conducted in the present study.

利用一个水稻籼粳交（窄叶青 8 号/京系 17 ）来源的 DH 群体对水稻柱头外露率、花柱长、柱头长、柱头宽、花药长、花药宽、颖花长、颖花宽和颖花长宽比 9 个花器性状和穗抽出度进行遗传分析。
