Considered as Fitzgerald's finest work, The Great Gatsby, written in crisp, concise prose and told by Nick Caraway, a satiric yet symphathetic narrator, it is the story of Jay Gatsby, a young American from the Midwest. Gatsby becomes a bootlegger in order to attain the wealth and lavish way of life he feels are necessary to win the love of Daisy Buchanan, a married, upper-class woman who had once rejected him.

a wafer of a moon was shining over Gatsby's house，。。。who stood on the porch， his hand up in a formal gesture of farewell：小说中的月亮总是与盖茨比相关，因为出身平凡的盖茨比妄称自己身份富贵显赫，正如月亮不仅仅从太阳那儿得到光亮，而且还是对太阳这个象征的浪漫的颠覆，空洞的言行强调了一项事实，那就是盖茨比苦心营造的优雅下忽隐忽现在是原本粗鲁的詹姆斯盖茨比。

灌装旋盖机该机是新型回转达式真空等压灌装带旋盖的联合机，采用了国际上流行的结构及原理。从空瓶进入到成品送出全部自动化控制，灌装旋盖精度高且无瓶不灌装不旋盖。

Because the workpiece is in dynamic balance, the resultant moment acting on it should be zero. Introducing the moment from lapping tool and press head a moving differential equation is built. In this equation only workpiece rotating speed is unknown. It means that workpiece rotating speed can be got by this equation. Since there is a transcendental function in integral function of the equation an analytic result can not be got, only digital result can be got by a computer. Thus a change rule of workpiece rotating speed with lapping parameters is known, e.g. the radius of press disc ball socket, radius of press head ball, the distance between the workpiece rotating axis and lapping tool rotating axis, workpiece radius, modulus of elasticity of the press head and press disc, friction coefficients between the lapping tool and workpiece, and between the head and disc, pressure between the lapping tool and workpiece and pressure between the press head and press disc.

因工件处于动态平衡状态，其上所受到的来自于磨具和压头的力矩应相等，将二力矩表达式联立，建立工件运动微分方程，该方程中只有工件的旋转角速度是未知量，因此可以求出工件旋转角速度，但该方程积分式中含有超越函数，得不出解析解，只能通过计算机求出数值解，得出工件旋转角速度随各研磨参数的变化规律，如压盖球座半径、压头的球头半径、工件回转中心相对磨具回转中心的偏心距、工件半径、压头和压盖材料的弹性模量、磨具与工件间的摩擦系数、压头压盖间的摩擦系数、磨具与工件间的压强、压头压盖间的压力等。

Through the preliminary study on the management of the population of Athyrium multidentatum, we found that the community of artificial Larix gmelinii forest has a high value of usage. Planting the population of Athyrium multidentatum may make us to improve the level of intensive management, and through the test this method is available. The population of the spacing in the row of forty cm in the community of Betulla platyphylla forest and the population of the spacing in the row of eighty cm in the community of artificial Larix gmelinii forest have the largest hight, leafstalk diameter and less herb coverage. The foodstuff technology of ferns is backward and the products are less, so we must improve the study on the usage of forest ferns.

通过对猴腿蹄盖蕨种群经营措施的初步研究，我们得出落叶松人工林群落是一个极具开发价值的群落；人工移栽猴蹄盖蕨种群，可提高集约化管理程度，经过试验，方法可行；白桦林群落株距40cm的猴腿蹄盖蕨种群高度、叶柄直径均最大，且杂草盖度较小；落叶松人工林群落株距80cm的猴腿蹄盖蕨种群高度、叶柄直径均最大；蕨菜食品加工技术落后、工艺简单、产品单一，今后应加强研究。
