One important feature ofHamiltonian systems is that it has energy(its energic function is Hamiltonian func-tion),then,its solutions on 2-dimensional plane are some contour lines,the points onstable manifold emanating from hyperbolic equilibrium point have the same energyas that on unstable manifold,then,one can guess that they form a closed curve,i.e.homoclinic orbits under certain conditions,and the contour lines in the innerpart of homoclinic orbit are periodic orbits.

哈氏系统的一个重要特征是它有能量存在(以Hamiltonian函数作为它的能量)，那么在二维平面上，它的解表现为一些等值线，从双曲平衡点发出的稳定流形和不稳定流形上的点具有相同的能量，那么可以猜测，在一定条件下它们构成一条封闭的曲线，即同宿轨，而且其内部的等值线都是周期轨道。

Horizontal lines denote size and position of patients exon-deleted; broken lines denote imprecisely defined breakpoints

横线表示患者所缺失外显子的范围及位置；虚线表示未能确定的断裂点

The final purpose of the lean production system is to satisfy customer's needs. Therefore, the flexible of production lines becomes a critical issue after production pattern has been changed from mass production to small-volume with large variety production. The manufacturing system of lean production is using management methods to survey the waste of production lines, to execute some kinds of improvability actions of reducing the cost, and to elevate productivity and quality to support various customization productions. By using lean production system, industries not only can earn profits but also can raise competitive advantage.

精实生产方式其最终的目的，就是要满足顾客的需求；因此当生产型态的转变由以往的「大量生产」转变为「少量多样」，创造生产线的弹性变成重要的问题，精实生产发展出来的生产系统，即利用管理手法检视生产线上的浪费，进行各种以改善为核心的降低成本活动，力求提高生产力、提升品质而提供消费者喜好的多样化产品，进而提高公司获利及企业竞争优势。

Based on the proposed genetic design, the maize inbreed lines JB and Y53, which are the parental lines of maize hybrid suyu 16 with strong heterosis, were used to create the mixed mapping population with two different cytoplasm backgrounds. The proposed method for mapping cytonuclear epistatic QTL were used to identify the cytonuclear QTL underlying maize agricultural and yield traits.

本研究在提出核质互作QTL分析方法的基础上，同时采用强优势玉米杂交种苏玉16(JB×Y53)的两个亲本自交系，配置具有不同细胞质背景的混合作图群体，构建分子标记连锁图谱，并采用本研究提出的核质互作QTL分析方法定位玉米重要农艺和产量性状相关的核质互作QTL。

Instead of using a sharp tool to incise lines, the painters used a fine brush, pen or reed to apply lines of purplish, red and brown color for the inner details of the figures.

而非使用一个锐利的工具切割线，画家用了好的刷子，钢笔或者芦苇为身材的内部细节应用带紫色的，红色的和褐色颜色的线。

With the expand of urban scope, great change have taken place in railroad hinge, many internuncial lines and lateral lines had been surrounded. Former status and function had been losed , capacity of transportation is surplus. Utilizing disengaged equipments and establishment to develop urban railway to service citizen , is becoming one of important approach to solved urban traffic jam.In this article, there are two important parts.

本论文在此双重背景下，以铁路参与城市客运为目标，通过分析国内外城市交通和轨道交通的现状及特点，在研究国有铁路参与城市轨道交通运营的可行性、必要性的基础上，对参与的重要性和意义进行分析，并对国铁参与城市轨道交通运营管理模式和行车组织方式做出了详细的论证和阐述。

It searches for the initial tracing point on intersecting lines and considers completeness of intersecting lines.
