Secondly, according to the stem and leaf anatomy, leaf epidermis, pollen morphology and floral development, it is found that there are no close relations between Acorus and Typhales, especially in the aspect of floral development. In the course of floral development of A. calamus, neither bracteloe primordium nor common primordium occurs in the whole course. Early development of the flower is strongly unidirectional. Three shield carpels develop into a pistil. In Sparganium fallax, each female flower has a bracteole. The bracteole primordium and the floral primordium originate from a complex structure. A single saccate carpel develops into a pistil. In staminate flowers, petal and stamen primordia initiate spirally.

菖蒲属与香蒲目的茎叶解剖特征、叶表皮特征、花粉特征及花器官发生特点等亦存在着明显区别，特别是花器官发生特点差异尤为显著，如菖蒲属花器官发生过程中，没有苞片原基，也不存在任何形式的复合原基，花被与雄蕊原基均以单向性方式发生，雌蕊由3心皮发育而成，具有"盾状心皮"的特点等，黑三棱属则有苞片原基发生，且苞片原基与雌花原基起源于共同的复合结构，雄花的花被原基和雄蕊原基均以螺旋状方式发生，雌蕊由单心皮发育而成，未发现有2或3个心皮原基或其痕迹的现象，体现出"囊状心皮"的特点。

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。

Fundamental concepts in power system differential-algebraic equations model, like singular point and multiple energy function sheets defined on constraint manifolds, are studied.

所得研究成果揭示了微分代数模型与奇异扰动模型的本质区别、奇异性与系统模型和系统负载的联系、结构保持能量函数法可能具有的内在保守性等，这对深入理解电力系统微分代数方程模型的拓扑结构、结构保持能量函数法和暂态电压稳定及其与功角稳定的关系具有一定的价值。

The concentrations of CO2, CF4, thionyl sulfide (SOF2), sulfuryl fluoride (SO2F2), disulfuryl decafluoride (S2OF10), sulfur dioxide (SO2) and sulfureted hydrogen (H2S) were in partial normal distribution. The concentrations of CO2, CF4, SOF2, SO2F2, S2OF10 were all below 0.1%; the concentrations of SO2 were below 3μL/L; the concentrations of H2S were below 1μL/L. The SF6 byproducts concentrations in 500kV GIS were lower than those in 220kV GIS. The SF6 byproducts concentrations were lower in GIS that have been operating longer. The SF6 byproducts concentrations were significantly different in equipment from different manufacturers.

结果显 示：SF6 GIS 中CO2、CF4、氟化亚硫酰（SOF2）、氟化硫酰（SO2F2）、十氟化二硫酰（S2OF10）、二氧化硫（SO2）和硫化氢（H2S）都成偏正态分布，其中，CO2、CF4、SOF2、 SO2F2、S2OF10 的含量均小于0.1％，SO2 的含量均低于3μL/L，H2S 的含量均低于1μL/L.500kV GIS 设备中SF6 分解产物含量低于220kV GIS 设备；运行时间越长，设备中SF6 分解产物的含量越高；不同设备厂商的GIS 中 SF6 分解产物含量有显著性区别。

Lastly, I argue that queer South Asian cultural politics be read as a critique of the 'spectacle', a representational practice that incorporates sexualized differences only through a fixation on racial difference.

最后，我认为南亚酷儿文化政治应该被看做是对这种景观的批评，这种再现强调种族的不同，从种族区别的角度定义性取向的不同。

PCD cutter's good characteristics make its cutting rule different with other normal cutter. PCD cutter's flank surface can press and polish the machining surface and the outstanding phenomenon will appear.

PCD刀具的优良特性使其切削规律与普通刀具的切削规律有所区别，其特殊性主要表现在PCD刀具的后刀面错位熨压作用，后刀面的错位熨压作用使得PCD刀具在精密切削时甚至会产生超越性加工现象。
