On the basis of taking full advantage of multi scale wavelet analysis,the proposed algorithm improves the contrast of the approximations of the wavelet transform through two lifting steps,and shrinkages the coefficients of wavelet transform on the diferent degree and then enhances the coefficients.

在多尺度分析基础上，该算法对小渡分解得到的低频子带图像采用两步提升法进行对比度增强处理，而对小波分解得到的不同方向上的小波系数进行不同程度的去噪并增强。

The focus of this design is automatically drilling vertical milling machine design, including the mechanical structure design, mechanical drive system design, and the choices and design of components on a table ,it is include: screw, timing belt, and the stepper motor Selection Guides; circuit is the main elements of the last part of the design , the control unit such PLC as the main can be quickly and easily complete the task of feeding the PLC's work, and designs the principles and procedures required by the design.

本设计的重点是自动立式钻铣床的设计，包括了机械结构设计、机械传动系统的设计，并对工作台的元件进行了选择和设计：包括丝杠、同步齿形带、步进电动机和导轨的选型；最后部分则是电路设计方面的主要内容，以PLC为主体的控制单元可以快捷方便的完成进给任务，对PLC的工作原理和本设计所需要的程序进行了设计。

The first step is separating bearing one by one to be weighing, then the microcontroller decide whether current bearing is good or bad based on the weighing data from the balance, make the electric magnate move to distinguish the good bearing from bad ones.

这是称重法的必由之路；第二步根据称重天平串口传来的数据，经由单片机判断控制继电器动作，实现轴承的分拣。同时讨论了对关键部件，轴承排序机构上，中，下盖的材料选取及主轴与带传动的设计方案。

To adopt band type rail rolled by stainless steel and chain type drive method run circumferential movement along with the pipe to be cut by flame cutting carriage,cutting torch will run radial movement driven by ball bearing screw by step motor along with the pipe to be cut,the above two dimension movement compose to inclined cutting movement of cutting torch,the inspection of circumference position of cutting torch,the determination of radial position and return point of cutting torch all controlled by SCM.

为了满足钢管斜截切割的要求，建立了钢管斜截切割的数学表达式，采用不锈钢轧制的带形轨道和链式传动的方式使火焰切割小车沿被切钢管做周向运动，割炬沿被切钢管的轴向运动由步进电动机带动滚珠丝杠完成，上述两维运动合成为割炬的斜切运动，割炬周向位置的检测、割炬轴向位置及折返点的确定均由单片机控制完成。

Look out! rang out a frightened cry from a soldier, and like a bird, with swift, whirring wings alighting on the earth, a grenade dropped with a dull thud a couple of paces from Prince Andrey, near the major's horse.

当心！可以听见一个士兵惊慌的喊声，一颗带着呼啸声疾飞的榴弹，有如一只向地面俯冲下来的鸟，落在离安德烈公爵两步远的营长的战马旁边，发出砰的一声。

Armed with shovels, shears, nets and clipboards, citizen-scientists across the country are discovering that observation is often the most critical step in identifying pollutants and protecting their own backyards and district waters.

带着铁锹，大剪刀，网和写字板，全国各地的科学家发现，观测常常是最关键的一步，识别污染物和保护自己的后院和当地的水源。

But the added advantage here is that, with a names ringtone, it brings customisation and personalisation a step further.

但好处是，随着铃声的名字，它带给定制和个性化了一步。

If ever I marry, and have daughters (which remote contingency may Heaven forefend!), they shall be educated in Paper Buildings, take their sole exercise in the Temple Gardens, and they shall never go beyond the gates till they are marriageable, when I will take them straight across Fleet street to St. Dunstan's Church, and deliver them into the hands of their husbands.

如果我结了婚，生了女儿（但愿老天爷预先防止这种遥远的万一之事），她们该在文件大楼里受教育，在法学协会的花园里作她们单独的体操训练，在她们可以结婚之前，她们不得走出大门一步，她们结婚时我才带她们穿过舰队街，直奔圣邓斯坦教堂，直接送到她们的丈夫手里。

The departure of Alexander from India caused a power vacuum into which stepped Chandragupta Maurya, an adventurer from a low-caste family.
