Aimed at the characteristic of retinal images, the algorithm of extraction of branch point and crossing point of vessels is proposed, the content includes the confirmation of the number of branch points and the precise extraction of the location of branch points. Branch point corresponding is determined by distance and the angles.

Now do we must discuss are not need to change,Should study,How but is you should quickly study,More accurate diastrophism,Only was invariable possibly is changes,Moreover or fast \ initiative diastrophism,Draws a inappropriate analogy,In the past everybody said ten years rub a sword, today we perhaps still needed for ten years to rub a sword,What but is different is we while rubs a sword also to want each hour to make to beat a dog the stick Otherwise, your sword does not have 磨出 to come, the neck on is wiped by yours enemy,Otherwise, the sword 磨出 has come also is the toy The competition is the war,I thought this selected already no need to doubt,The present age, the plagiarism and the surmounting speed nearly already was the speed of light, the people do not even have the time calmly to get down the personal status own achievement.

请高手按照演讲的体裁来翻译：如今的年代我们所要讨论的不是需不需要变化，应不应该学习，而是你应该如何更快地学习，更准确地变化，唯一不变的可能就是变化了，而且还是快速地\主动地变化。打个不恰当的比方，过去大家都说十年磨一剑，今天我们也许仍然需要十年磨一剑，但是所不同的是我们在磨一剑的同时还要每小时制造一根打狗棒。否则，你的剑还没有磨出来，脖子就被你的敌人抹了，而且我们在磨剑的间隙里，要不断地\想方设法地了解一下我们磨剑的方法是否先进，否则，剑磨出来了也是玩具。竞争就是战争，我想这点已经没有什么需要置疑的了。

Many traditional compiler optimizations fall into this category: copy and constant propagation, redundant expression elimination, dead code elimination, peephole optimizations, function inlining, tail recursion elimination and so forth.

许多种传统的编译器优化方式都可以归结于这两种方法，比如说：copy and constant propagation（用常数取代程序中不变化的变量），冗余表达式消去，死代码消去，Peephole优化，Inline函数，尾部递归消去（展开在程序尾部的递归，减少堆栈消耗

Main contents and conclusions are: 1 The ionization current was measured continuously by a charge-integration method with a computer after the introduction of radon into the chamber.

主要内容及结论：1充氡后利用计算机连续进行电离电流累积测量，得到了精细的电流随时间的变化曲线，可清楚看出氡及其子体的生成衰变造成的电离电流的生长—稳定—衰减过程，与理论计算值进行了比较，由电离电流衰减速度的变化得出氡吸附作用的影响，并测量到电离室冲洗后氡的反扩散现象；2由已知活度的标准源定出相对测量的刻度系数K值，K=24.62 Bq／pA，对同一个监测源以半年为周期进行多次测量后得出稳定性符合要求；3通过测量电离电流和气压的关系曲线以及不同气压下的饱和曲线，确定了常规的工作条件；4测量了盐酸清洗电离室内表面降低本底的效果；5不确定度分析表明相对测氡的扩展不确定度(k=2)小于5％，由本底涨落得出探测下限为0.5 Bq；6理论上对壁损失修正进行了计算，实验上保持电离室工作在饱和区的情况下，测量了不同气压下电离电流的变化，从中得出了壁损失随气压变化的规律，可以看出，电离电流的实测值和计算值随气压变化规律基本一致；当气压大于125 kPa时，端效应等其它因素造成的影响不大于2％，因而在此工作条件下，测量电离电流后通过计算修正壁损失可以实现近似的绝对测氡，提出了进一步提高绝对测量准确度的方法。

Jet lag jet 会使人们想到jet plane,lag是指"延迟的时间",在技术上称为"时滞"或"滞后".jet lag =jet fatigue=jet syndrome anthur j.snidir在the rhythm of life对jet syndrome的解释是:symptoms of biorhythm upset,known popularly as the jet syndrome,are experienced by jet airplane travellers who fly through several time zones in 12 hours or less.the local time between their place of departure and their destination may differ by 5,6,or even as much as 10hours.

jet lag是随着喷气式飞机的问世，乘喷气式客机旅行的人越来越多的情况而出现的。jet lag不是什么喷气时滞，而是人们在乘坐喷气式飞机旅行时由于时差的关系而引起不适应目的地昼夜变化的一种疲劳和烦躁的现象。

Alteration of Spanish tomate 西班牙语 tomate的变化 from Nahuatl tomatl 源自那瓦特语 tomatl It has been said that the real contributions to world civilization were made by the unknown inhabitants of the Americas who domesticated plants such as the potato and squash and not by the great pre-Columbian civilizations, including that of the Aztecs.

据说对世界文明真正作出贡献的并非是包括阿兹特克文明在内的哥伦布到达前的美洲文明，而是那些家庭种植土豆、南瓜等的不知名的美洲居民。

They are as follows:(1) the change of communication mode from off-line spoken language to on-line written language in the learning environment;(2) the change of process structure from passing on—compelling remember—getting information to choosing information—sharing information—regenerating information in the learning mode;(3) the change of institution pattern from concentrated, hierarchical, slaved to distributed, net, protocol in the learning institution;(4) the change of main connotation from independent-receive to share-reconstruct in the learning concept;(5) the change of the level for needing non-cognitive factor in the psychology.

本文还进一步追问了导致学习不适应的诸种因素的成因，得出（1）学习环境中由网下面对面语言交流转入网上文字交流的交往方式的变化；（2）学习方式中由传授→被动接受→强行记忆→获得信息转入选择信息→共享信息→再生信息的过程结构的变化；（3）学习机构中由集中层次隶属式到分布网状协议式的组织形态的变化；（4）学习观念中由独立-接受到共享-建构的学习内涵的变化；（5）学习心理中非认知因素需求程度的变化等导致学习不适应的5成因。

There is nothing in existence that is unchanging .

It's not without hesitating and never turns back unless knock into the wall.

我们不要把市场看成单一的、不变化的，市场不是不见棺材不掉泪，不撞南墙不回头的。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
