For example, we study the properties of the"centroid curve" and the"auxiliary curve", and identify two planes in which these two curves are defined respectively; we also use the idea of homotopy method to prove a fact that the orbit of a differential system has no triple contact point with the line we considered. Another key technique, which we use several times, is deformation argument.

例如研究由Abel积分之比定义的"质心曲线"和"辅助曲线"的几何性质，并把这两条在不同平面上定义的曲线放在同一坐标系中考虑；利用拓扑中同伦的思想来证明微分系统的轨线不可能与某条直线三重相切；利用几何方法与分析计算相结合证明了某一曲线是正则的；以及连续变动参数的技巧。

To meet requirement of production and quicken rolling speed, No.2 heating furnace was put into operation in 2002 and No.3 in 2007. All automatic control was adopted, displacement of walking beam was detected by displacement transducer, and acceleration and deceleration control of walking beam was carried out through proportional valve and by use of slope technique in program of GE 90-70 PLC, thus, travelling speed of walking beam can be controlled and lift and release of slab can be operated lightly.

为适应生产的需要，加快轧制速度，2002年投产的2号加热炉和2007年投产的3号加热炉均采用全自动控制，利用位移传感器检测步进梁的位移量，通过比例阀以及在GE90-70PLC程序中采用斜坡技术对步进梁运动进行加减速控制，达到控制步进梁运行速度的目的，实现对板坯的轻拿轻放。

PV, IP, register user number, wait a moment etc,"Do not be fed up with, but no-good ", especially cash is not swelled not only, and one every day use up almost to use up, young man of the man in old man people it is a pair of woebegone appearance.

PV、IP、注册用户数，等等等等，"不讨厌，但毫无用处"，尤其是钱不仅不涨，且一天天的消耗殆尽，大佬中佬小佬们都是一副愁眉苦脸的样子。

With my newer mod, not only do they have the stronger economy, they can also leverage gold boni into research, what's more they no longer squander Great People, meaning they might use that mid game GS to pop Education and thus win liberalism rather than wasting him on a GA, the AI who bags the Economics GM will probably use him for a Cash Bomb, resulting in another burst of research.

他们不仅经济强，而且他们可以利用钱做研究。他们不在浪费伟人，比如他们可以用大科发现教育学进而发现自由主义，而不会浪费在建立研究院。有大商人的AI会用它挣钱，然后把钱花在研究上。

The conclusions are: aftereffects of failure are that the land use planning and land use year scheme were break optionally, no-land's inhabitants were emergent, partial magnificent economy is calefactive.

研究结论：土地作为宏观调控工具存在政府失灵，后果为土地利用规划和土地利用年度计划随意突破、产生无地居民、局部宏观经济过热。

This thesis deeply researches the J2EE security strategy on the application tier of enterprise system. The security strategy predigests the information security model and meets the security requirements expediently. But there are some disadvantages when the security requirements become more complex. The expositive security on the Web-Tier can not offer more information for authentication; there is no authentication for EJB-Tier to use, make the EJB-Tier depend on the Web-Tier; J2EE uses database or application server to manage the role information. Use database to manage the role information will increase the complex of enterprise application, and the way of application server will reduce the ability of migrate other J2EE platform. To solve these problems, the thesis designs an improved security strategy model.

本文从企业级系统应用层安全的角度出发，深入研究J2EE多层体系结构的安全策略模型。J2EE提供的安全策略简化了系统的信息安全模型，能够很方便地满足基于J2EE的分布式应用系统的安全需求，但是在面对更加复杂的安全需求时，J2EE安全策略在验证授权和角色管理中还存在不足之处：其在Web层的声明式验证机制无法为用户提供更多验证信息，可扩展性较差；在EJB层缺少业务逻辑层可供采用的验证机制，而是借助于Web层的验证机制，其耦合程度较高有悖于业务逻辑分离于表现逻辑的原则；在角色管理方面，J2EE采用数据库或者应用服务器来管理角色信息，其中，数据库管理角色的方式增加了应用开发的复杂度，应用服务器管理角色降低了系统的可移植性，两者都具有片面性。

As to'Cabemet Sauvignon'and'Queen of Vineyard', which belong to the'West Europe Cultivars Group', no obvious decline of Fv/Fm was found in their potted plants even under severe drought stress. Their photosynthetic abilities also greatly recovered after rewatering, i. e. no serious photodamage was formed in these cultivars under drought stress. Between them, the φPSⅡ of 'Queen of Vineyard'under severe drought stress was much lower than that of'Cabernet Sauvignon', which suggested that the light use efficiency of the former was much lower than the latter under severe drought stress. The potted plants of'Autumn Royal'and'Rizamat' sustained high Fv/Fm and φPSⅡ before moderate drought stress, but seriously declined under severe drought stress, which indicated that these cultivars had a weak resistant ability to extreme drought stress. A hybridized cultivar of Vitis vinifera L. and V. labrusca L.,'Red Double Taste', its Fv/Fm and φPSⅡ expressed mild decline along drought stress grade.φPSⅡ of'Red Double Taste'was the highest among seven cultivars under severe drought stress condition, which might closely connected with its high photorespiration activity. Another new cultivar,'Red Globe', and a rootstock,'1103Paulsen', the Fv/Fm and φPSⅡ of their potted plants declined markedly under slight drought stress, which suggested that they held a weak ability to defend against photoinhibition.

西欧品种群的赤霞珠和葡萄园皇后，其盆栽苗的Fv／Fm直到重度干旱胁迫下仍没有明显的降低，且复水后光合能力恢复程度较高，即干旱没有给这两个品种造成严重的光破坏，而两个品种之间，葡萄园皇后在重度干旱胁迫下的φPSⅡ明显低于赤霞珠，说明其光合器官在严重干旱胁迫时对光能的利用率较差；新品种皇家秋天和东方品种群的里扎马特在中度干旱胁迫下仍可维持较高的Fv／Fm和φPSⅡ，但在重度干旱胁迫下则降低幅度较大，说明其抵御极端干旱胁迫的能力较差；欧美杂种红双味的Fv／Fm和φPSⅡ随着干旱胁迫程度的增加呈现平缓的下降趋势，而且其φPSⅡ在重度干旱胁迫下是七个品种中最高的，这应该与其此时仍维持较强的光呼吸活性有关；红地球和砧木1103Paulsen的Fv／Fm和φPSⅡ在轻度干旱胁迫下就明显下降，表明干旱条件下其抵御光抑制的能力较差。

There's no more messin' around This could be the start of something Why don't you party-up Time for you to come on down I dream about it in my sleep You seem to like me better when I creep This time I won't lose You roll me, you use me, you love me and then You wrap me up and reel me in and use me again You love me, you hate me, you say it's the end I know your gonna do it again and again... I didn't see this coming Why don't you start me up?

这不是没有其他着能是某事的开始为什么不您党您的时间能进展下来我梦想对此在我的睡眠当我爬行时，你似乎喜欢我更好这时间我不会丢失你滚动我，您使用我，您爱我然后你包裹我并且卷我并且再使用我你爱我，您恨我，您说它是末端我知道您去再次做它…位没有看这来为什么不您开始我？
