黄铜的

The polishing fluid is composed of Al2O3 micropowder with a grain diameter of 0.5-1.0 mum, coal oil, lard, plant oil and spindle oil, wherein Al2O3 micropowder is abradant, coal oil is solvent, the mixing liquid of lard, plant oil and spindle oil is as additive; and the polishing fluid is prepared by a mixing liquid which is composed of 2% lard, 2% abraser, 8% plant oil and spindle oil by volume and 88% coal oil. The polishing fluid can produce the H62 brass element with a uniform surface quality and a good surface roughness value up to 0.008 mum, has the characteristics of no eroding elements, effectively relieving mechanical score, good processing surface quality and can be used for decoration of the plastic metal material and surface polishing process before the material metallographic microscope analysis.

抛光液由粒径为0.5～1.0μm的Al 2 O 3 微粉、煤油、猪油、植物油和锭子油混合而成；其中Al 2 O 3 微粉为磨料，煤油作溶剂，猪油、植物油和锭子油的混合液作添加剂；抛光液按体积比由2％的猪油、2％的磨料、8％的植物油和锭子油的混合液、88％的煤油配制而成；该抛光液能够加工出表面质量均匀，表面粗糙度值达到0.008μm的H62黄铜工件，具有不腐蚀工件、有效缓解机械刻划作用、加工表面质量好的特点，可以用于塑性金属材料的外观装饰性加工，以及材料金相分析前的表面抛光加工。

Traversing the long and matted gallery, I descended the slippery steps of oak; then I gained the hall; I halted there a minute; I looked at some pictures on the walls (one I remember represented a grim man in a cuirass, and one a lady with powdered hair and a pearl necklace), at a bronze lamp pendent from the ceiling, at a great clock whose case was of oak curiously carved, and ebon black with time and rubbing.

我穿过了铺席的长走廊，下了那光滑的橡木楼梯；于是我到了过厅，在那里站了一会，我看着墙上的画（我记得有一张画着穿护身甲的严肃男子，一张画着戴宝石项链，敷发粉的贵妇），看着从天花板悬下的黄铜灯，看着一座大钟，钟架是雕得石怪的橡木，和因为时间与磨擦而发了黑的乌木做成的。

Traversing the long and matted gallery, I descended the slippery steps of oak; then I gained the hall: I halted there a minute; I looked at some pictures on the walls (one, I remember, represented a grim man in a cuirass, and one a lady with powdered hair and a pearl necklace), at a bronze lamp pendent from the ceiling, at a great clock whose case was of oak curiously carved, and ebon black with time and rubbing.

我穿过铺着地毯的长走廊，走下光滑的橡木楼梯，来到门前。我站了一小会儿，看看墙上的画（我记着一幅画画了个身穿胸甲的严肃男子，一幅画画的是擦着发粉带着珍珠项链的妇人），看看从天花板垂下的黄铜灯，看看那个黑木大钟，钟架上有古怪的橡木雕刻，因为长时间的摩擦，已经变黑了。

It pendulum swung to and fro with a dull, heavy, monotonous clang; and when the minute-hand made the circuit of the face, and the hour was to be stricken, there came from the brazen lungs of the clock a sound which was clear and loud and deep and exceedingly musical, but of so peculiar a note and emphasis that, at each lapse of an hour, the musicians of the orchestra were constrained to pause, momentarily, in their performance, to hearken to the sound; and thus the waltzers perforce ceased their evolutions; and there was a brief disconcert of the whole gay company; and while the chimes of the clock yet rang.

每当长针在钟面走满一圈，临到报时之际，大钟的黄铜腔里就发出一下深沉的声音，既清澈又洪亮，非常悦耳，然而调子和点子又如此古怪，因此每过一小时，乐队里的乐师都不由得暂停演奏来倾听钟声；双双对对跳着华尔兹舞的也不得不停止旋转，正在寻欢作乐的红男绿女不免乱一阵子；这且不说，钟声还在一下下敲的时候，连放荡透顶的人都变得脸如死灰，上了年纪的和老成持重的都不由双手抚额，仿佛胡思乱想得出了神。

Based upon the experimental results, including threshold values under static loading,the effects of alternating loading and room temperature creep,as well as metallographic observations of the fractography,it is concluded that notwithstanding stress corrosion or corrosion fatigue in aqua ammoniae,or fatigue in air,the cracks always initiate at the site subject to maximum normal stress(θ=-110°)along the notched surface,and then propagate along the maximum shear stress direction from that site(α=-35°).

由门槛值的测量、交变载荷的作用、室温蠕变的影响、断裂过程的金相观察及断口形貌等结果，可以确认；黄铜不论是在氨水中应力腐蚀或腐蚀疲劳，还是在空气中疲劳，裂纹都从Ⅱ型缺口试样的最大正应力处(0=-110°)萌生，并沿该处的最大剪应力方向(α=-35°)扩展。

The theory of the simulation is that, firstly put fuze and parts in simulation device in reverse, then fire them in high speed by air gun , and they fly into gun spinning quickly and impact cushion and brass block in it , negative acceleration because of impact is to simulate setback , meanwhile they spin with spin gun when impacting, so spin environment can be simulated, so the simulation system can stimulate setback and spin of fuze in fire.

该模拟系统的原理是将引信及其零部件倒置在模拟弹丸中，通过空气炮以高速发射出去，然后飞入高速旋转的旋转管内，与旋转管内的缓冲块和黄铜块碰撞，碰撞而形成的负加速度作为引信发射时受到的后坐，由于碰撞时与旋转管一起旋转，模拟引信发射时的旋转环境，达到模拟引信发射后坐与旋转环境的目的。

This classification of the world is important because like Sugimoto's stunning epiphany, the effect of Tapaya's visual universe is almost narcotic and otherworldly, considering that myths of creation define this oeuvre and that the dioramas, silver-coated brass boxes with embossed embellishments, look like Catholic altars or Hispanic ex votos meant for supplication and entreaties to spirits.

鉴于Sugimoto令人眩目的出色表现这种对世界进行分类的方法也变得重要起来，塔帕雅的视觉宇宙有一种超脱俗世的麻醉作用，思考一下在这套作品和立体空间中所定义的创世神话，画面中黄铜镶银的浮花装饰看起来极像天主教徒的祭坛，或者西班牙人和葡萄牙人向主祈祷的拜坛。

无论你是否曾经在单板公园耍酷或者是在雪山上巡航，这款板都不仅仅发挥出他那双重过渡的边刃以及加倍密度的板底，而且他还是一个地地道道的左右对称的板头设计用于征服每一个跳跃或者是跐杆，高弹性的黄铜刃将更加的耐磨并且能使你的刃在铁杆上不会被撞断或者被卡住。
