分析了大锥面包络环面蜗杆的齿顶变尖和根切规律，并通过和平面包络环面蜗杆的比较，得出其在根切和齿顶变尖这两个方面具有比平面包络蜗杆更优良的性能，因而是一种在实际中可替代平面包络、具有广泛应用前景的新型包络蜗杆传动。

Other diagnostic features include the presence of a crest along the anterodorsal midlines of the premaxillae,the edentulous maxilla,the presence of a groove-like trough along with the anterolateral margin of the maxilla on the ventral surface,the presence of six conical premaxillary teeth,and no more than six conical dentary teeth which are restricted to the anterior portion of the dentary.

其他主要特征有：前颌骨沿前背中央有一隆嵴；上颌仅前颌骨有6枚圆锥形齿，无上颌骨齿；上颌骨沿前腹侧缘有一沟槽；下颌齿骨齿都集中在前端且至多不超过6枚。依据上述这些特征很易把短吻贫齿龙与其他已知海龙相区别。短吻贫齿龙头骨顶面松果孔大且很前位，头骨腭面的锄骨和翼骨均无齿，它的颈较长(至少可以辨认出13个颈椎)。

Finished product conical roller whose half angle is greater than 3°is called big cone angle conical roller .

成品圆锥滚子半角大于3°的即为大锥角圆锥滚子。

Through model test of new high- strength steel conical shell with ring frame ,and relevant analysis,it is shown in this paper that the failure of ring-framed conical shell can be traced to the neutral plane on longitudinal section where the structure strength is relatively weak.

通过新的高强度钢材环肋圆锥壳模型实验，及采用解析方法分析表明，环肋圆锥壳体破坏的原因是结构相对薄弱处纵剖面上的中面应力所致。并提出用"灰色系统"理论预测破坏载荷的计算方法，建议今后模型实验和现役潜艇的耐压船体寿命估算中可采用这种方

By using Whitham rule, this paper analyzes the characteristics of pressure and temperature of the oscillating gas in the conical resonance tube theoretically and explains why the conical resonance tube can reach higher temperatures than the cylindrical resonance tube.

文中利用Whitham规则，从理论上分析了在圆锥形管中振荡气体的压强和温度特性。

Because the conical resonance tube can enhance shock waves, the gas at the end of the conical resonance tube has higher pressure oscillation amplitudes and higher temperatures and heating rates than that at the end of the cylindrical resonance tube.

因为圆锥形谐振管对激波有增强作用，所以在相同条件下，圆锥形谐振管中气体压强的振荡幅度和加热温度、速度都要高于圆柱形谐振管，因而圆锥形谐振管加热性能比圆柱形谐振管好。

Because the gas at the end of a conical resonance tube can be heated to a higher temperature more quickly than at the end of a cylindrical resonance tube ,researchers pay more attention to the conical resonance tube in the engineering field of the gas-dynamic resonance ignition technique of liquid propellant rocket engine.

在液体火箭发动机气动谐振点火技术中，圆锥形谐振管因气体谐振加热温度高、加热速度快而受到重视。

Aiming at solving the difficulties of prototype manufacturing of conical ring for the steam generator shell of 600MW Nuclear Reactor,this paper developed a new techniques for the prototype manu-facturing of the great conical ring utilizing ring rolling technology based on RAW200/160-5 ring rolling.

1引言600MW蒸汽发生器壳体是核电站的关键设备，由封头、锥形环件和筒体组焊而成。以往制造这种锥形环件所采用的办法是，先锻制环形筒件再采用机械加工方法成形或者采用自由锻造方法直接在水压机上锻制出大型锥形环件，但这些工艺既费工时又大量浪费材料，而且产品精度不高[1]。

Analyse the technology principle of program tracking, step-in tracking, conical scan tracking and singleshot tracking, and contrast the advantage and disadvantage of them. Select program tracking and conical scan tracking considering performance and cost.

二、对程序跟踪、步进跟踪、圆锥扫描跟踪和单脉冲跟踪这四种自动跟踪技术的原理进行了具体的分析，并比较了它们各自的优缺点，从性价比的角度，选择了程序跟踪与圆锥扫描跟踪相结合的方式。

In this paper ,to overcome the shortcomings in 3MK133 Groove Grinder's hybrid spindle system that the shallow slots of the throttler are easy to be blocked and difficult to be disassembled to clean,we use the throttler which is put on the big-side surface of the conical bearing to replace the traditional throttler, change gap throttling to capillary throttling, and adjust the taper of the conical bearing , oil return way , seals and sealed mode.

针对 3MK133沟道磨床动静压主轴系统中，节流器浅沟容易堵塞及拆卸清洗不便等缺陷，提出采用端置式节流器替代原有的内置式浅沟节流器，变间隙节流为毛细管节流，并相应调整了主轴系统中圆锥轴承的锥度、回油通路、密封装置及密封方式。

He paid $5,000 for this cupcake.
