For the all classes of dies, if we analyse the fluctuate, tendency of increase and decrease and law which appeared in the die's whole life, we will find that the master of the error are changeless; the error that because the abrade of the cutter and impression will be as the cutter grinding times increased at the same time. And that will cause the error oversize gradually; and also have another part error are unconventional , unforeseen.

对各类冲模冲件误差在冲模整个寿命中出现的波动、增减趋向及规律等进行全面分析便可发现：冲件误差的主导部分是不变的；因刃口或型腔的自然磨损而出现的误差增量随冲模刃磨冲数增加而使这部分误差逐渐加大；还有部分误差的增量是非常规的、不可预见的。

Considering complicated conditions of the coastal dynamic environment, sediment dynamics, and together with the immature sediment itself, the predicted results will be somewhat limited if only with numerical model. So, in order to obtain microcosmic quantitative assessment and macroscopically understanding, numerical model is combined with field observations in the thesis. Firstly, the tidal current, SSC distribution, benthal deposited materials were basically analyzed by field observations. Then, the tidal current, SSC distribution, and the erosion and accumulation of the seabed were simulated with the numerical model of ECOMSED.

但由于海岸动力环境多变，泥沙运动复杂，加之泥沙问题本身的复杂性，如仅用数学模型，其预测结果将受到一定的限制，故本文采用实测调查与数学模型计算相结合的方法，宏观把握，微观量化，在掌握岚山港西突堤工程所在海域潮流、悬沙量分布、表层底质沉积物类型及特点基本态势的基础上，紧扣开发工程可能引起潮流场变化，分析工程后悬沙量、海底冲淤变化及其空间分布，进而建立潮流作用下的泥沙输运数学模型，首先比较好地模拟目前岚山港西突堤工程附近海域的潮流场和悬沙场，然后预测海湾沿岸可能引起的冲淤强度变化和冲淤区域的空间分布。

尼亚加拉瀑布的水流冲下悬崖至下游重新汇合之后，在峡谷里继续翻滚腾跃，在不足2公里长的河段上以高于大瀑布的流速每小时35.4公里跌荡而下15.8米的落差，演绎出世界上最狂野。最恐怖。最危险的漩涡急流，又冲进深38的漩涡潭，然后一个蛟龙翻身，经过左岸加拿大的昆斯顿。右岸美国的利维斯顿，冲过"魔鬼洞急流"，沿着最后的"利维斯顿支流峡谷"由西向东进入安大略湖。

In this paper,a completely different method based on charge and flux conservation at the switching instants for obtaining the initial conditions after switching is presented.

但当电路中出现冲激函数，如冲激电源，或因换路出现冲激变量时，这种论述就受到限制[1，2]。

Wedge mechanism was adopted in piercing die to achieve side piercing, and the positioning of taper pipe depended upon the conical surface of blanking die itself.

在冲孔模中选用了带有楔角的斜楔机构来实现侧冲，并利用冲裁凹模自身的锥形面实现了锥形管的定位。

Tengchong International Youth Hostel is located on the biggest private garden-Yuquanyuan, which is in the center of Tengyue old village.

腾冲是个清醒而又温情的边疆小镇，有宽净的街道和无边的绿色，让漂的人有充足的空间静静呼吸……清晨骑着自行车疾驰，呼吸着清冽的空气，第一道阳光明亮刺目得让人微微眯起双眼，街边随处是热气腾腾的早点铺，稀豆粉粑粑、煮饵丝……让内心沉静的人对新的一天有了美好的期许……腾冲人挣了钱有两用，一为供子女读书二为盖房子，所以不论贫富，家家单家独院，有个漂亮的天井，自古留下来的众多古老民居更是青砖瓦房，蔷薇藤蔓……腾冲国际青年旅舍开设于古朴别致的滇西最大私家花园--玉泉园内，正处腾越古镇文化中心。

I was loath to spend our last Shot too hastily; so I call'd my Servant, not my Man Friday, for he was better employ'd; for with the greatest Dexterity imaginable, he had charg'd my Fusee, and his own, while we were engag'd; but as I said, I call'd my other Man, and giving him a Horn of Powder, I bad him lay a Train, all along the Piece of Timber, and let it be a large Train; he did so, and had but just Time to get away, when the Wolves came up to it, and some were got up upon it; when I snapping an uncharg'd Pistol, close to the Powder, set it on fire; those that were upon the Timber were scorcht with it, and six or seven of them fell, or rather jump'd in among us, with the Force and Fright of the Fire; we dispatch'd these in an Instant, and the rest were so frighted with the Light, which the Night, for it was now very near Dark, made more terrible, that they drew back a little.

我不愿匆匆放完最后一排枪，就叫来了自己的仆人。我没有叫星期五，而是叫了我新雇的那个水手。星期五有更重要的任务要完成。在我们开火的时候，他以惊人的速度给我和他自己的枪装弹药。所以我说，我叫的是新雇的仆人。我给了他一角火药，命令他沿着那根长木头把火药撒下去，撒成一条宽宽长长的火药线。他照着办了。他刚转身回来，狼群就冲了过来，有几只甚至已冲上了那根长木。我立即抓起一支没有放过的手枪，贴近火药线开了一枪，使火药燃烧起来。冲上木料的几只狼给烧伤了；其中有六、七只由于火光的威力和惊恐，竟连跌带跳地落入我们中间。我们立即把它们解决了。其他的狼被火光吓得半死，加上这时天已黑下来，火光看起来就更可怕了，这才使那些狼后退了几步。

The average depth of erosion on gritstone for cavitation water jets is 2 times as much as common water jets, and its mass erosion is 7 times as much as common water jets, and its diameter of erosion is 2.3 times as much as common water jets.

对于含有空泡的磨料射流，围压增加空化噪音减少，泵压增加空化噪音增加；有效靶距直径比增加，对花岗岩的冲蚀深度与冲蚀质量存在一最优有效靶距直径比；在最佳冲蚀时间下，较纯水空化射流工作效率提高2倍。

So we rush, rush, rush to get to certain ideal point in our life , and them what?

所以我们冲，冲，冲，为了我们生命中一定的理想，结果呢？

The hydraulic angle semi automatic product line is mainly used in punching and printing procedures of equilateral and inequilateral angles with their side length of 160 mm and smaller ones; leaves out lineation on angles and alinement when punching one by one; it only needs to input such parameters as the positions of each hole and of printing; put the angles to be processed on the pincer of the cart; then, automatic consecutive punching can be realized.

本液压角钢半自动生产线主要用于边长160mm及以下各种等边不等边角钢的冲孔及打字工序，省掉在角钢上逐一划线及冲孔时逐一对线的作业，只须按一定程序将各孔位置需打字位置等参数输入计算机，将所需加工角钢装在小车夹钳上后，即可实现自动连续冲孔。
