After investigating the evolving of tax systems in the world and the rising of income tax in developed countries, the author suggested the way to optimizing Chinese tax revenue structure is to set up a two-main-body tax system with turnover tax and income tax. The conceived outline is to augment the income taxation, to adjust the comparative proportion between turnover tax and income tax, and hence to change the distorted tax system and set up a two-main-body one, in which turnover tax and income tax can function congenially and complementally.

在分析成因、指出弊端和改革必要性后，本文通过对税制演变的规律总结和发达国家所得税上升为主体税种的过程考察，提出优化我国税种收入结构的方向是建立双主体税种结构，总体思路是在稳定流转税收入的情况下，增加所得税的规模及在税收收入中的比重，以动态的方式改善商品流转税和所得税的相对比例，改变我国税种收入结构失衡、税制功能扭曲的现状，构建一个流转税和所得税结构协调、功能互补的双主体税种结构。

Solid carbide tungsten fishtail drill is suitable for pcb flexible foil clad laminate,used for target machine drilling,the features of pcb fishtail drill are thin and flexible plate,it's structure and cutting methods are different with normal pcb drill bits.its two main cutting edge is concave and formed 100degree angle,in order to distinguish with PCB drill,named fishtail drill.fishtail drill cuts beginning of circular drill.concave along the main cutting edge to cut,chip is just two much fine filament.cuttingis falling off naturally,in order to be processed without burrformation by pcb surface.

整体硬质合金鱼尾钻适合印制电路板行业加工挠性覆箔板，为打靶机钻孔用。鱼尾钻所加工的印制电路板特性是薄板、带柔性、这样就决定了它的结构和切削方式与一般PCB钻不一样，它的两主切削刃是内凹的，两主切削刃形成100度的夹角，为了与PCB钻区别，就叫它鱼尾名。鱼尾钻切削时从我圆处钻尖开始，沿着内凹的主切削刃切削，切屑只是两条极细丝状切削，整个切削自然剥落，从而被加工印制板表面平整无毛刺。

Result: The patients were most younger than 60 years old and older than 40 years old (67.7%). The average age was 47.A greater incidence was observed among Uygurs (80.3 %) and presents in each region, and this was undoubtedly related to their lower socioeconomic status. Increased occurrence of cancer of cervix in women was probably related to the factors such as age at first marriage, age at first pregnancy, copiousness and multiple sexual partners. The patients who first visit are mostly diagnosed in regional hospitals which were deficiency of effective treatment(90.8%). Squamous cell carcinoma is the main pathological type. Exoginic and anabrosis are the main morphous types. The percent of stage I is 8.4%,but percent of stage II -IV is 91.6%.
