On the base of the single-diameter laser-scanned measuring technology, a double direction laser-scanned measuring system is presented. Which combinate the laser-scanned measuring technology with special optical system. In the system, the collimation semiconductor laser-scanned beam scanning two perpendiculars direct of one plane of the measured workpiece at the same time is made. The beams with the dimension information of two perpendiculars direct are processed by the scanning receive system, the high-speed photoelectric transition and electronic data process. Two measured results of the diametric directs and ellipse tolerance,etc, parameter, of the turning workpiece on the same plane are obtained by non-contact automatic measurement. The problem of non-contact measurement of two perpendiculars direct of one plane of turning workpiece is settled. It processes many peculiarities, such as high speed, high accuracy and non-contact automatic measurement, etc.

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。
