Cone vacuun mixing drier increases vacuun drying/ heating/ cooling. etc functions on the basis of cone helix mixer.Because it uses widy.during the period of manufacture much attention has been paid to rationality and convenient.Special design at shaft seal/screw support and thickness of cone plate is increased.

圆锥型真空混合干燥机，是在圆锥型螺旋混合机上，增加了真空干燥/冷却等功能，由于用途广泛，因此特别重视制造过程中的合理性及便利性，该设备在轴封/螺旋支撑部及锥体板厚等方面增加特别的设计，基本结构与圆锥型螺混合机相同。

Numerical controlled program was compiled with ETA code. The baffles were welded into a pile, then the holes were drilled using milling cutter and twist drill. The baffles were installed on Mitsubishi numerical controlled machine, and numerical controlled process was realized. This can improve production efficiency, which makes it possible that helix-baffled tubular heat exchangers can be widely applied in factory.

在MITSUBISHI操作系统的数控钻铣床上，采用特殊的刀具，将折流板点焊为一擦，装夹在旋转工作台上，使之与刀具成一个固定角度，实现了阶梯式螺旋折流板上孔的加工，解决了制造的难题，提高了生产效率和钻孔精度，为螺旋折流板管壳式换热器的推广应用提供了可能。

We measured the CT value of different quality of the plague in the image of 64-slice CT coronary angiogram.

评估64层螺旋CT对冠状动脉狭窄性病变及支架诊断的准确性，在64层螺旋CT影像上测量不同类型斑块的CT值。

Due to the TomoTherapy machine intrinsic characteristics, some mechanical items, such as the gantry, the couch angle, the collimator etc., do not need to be checked. Additionally, no electron beam verification is needed but the same beam effect can be formed from the different beamlets of the machine.

再者，由於多模式螺旋断层放射治疗仪机器的本质结构特性，有些品质保证测量项目不须实施，如在机械方面不须要做旋转臂、治疗床、准直仪之品质保证测量校正工作，所以在例行的品质保证测量工作上较为简单；此外因多模式螺旋断层放射治疗仪只有单一光子射束(6MV)，而没有电子射束所以在品质保证量测上不须测量电子射束，因而简化许多程序，但电子射束的特性可以由不同的小射束组合来达到相同的效果。

There are three forms of symmetry in virus capsids: icosahedral , helical and complex forms.

壳粒排列的方式使病毒的结构呈几何对称，病毒衣壳有三种对称形式：二十面体立体对称、螺旋对称、复合对称，螺旋结构呈杆状，而二十面体由对称的亚单位组成近似的球状，非对称的衣壳是较复杂的形式，往往与细菌病毒有关。

Finally he comes to Isidora, a city where the buildings have spiral staircases encrusted with spiral seashells, where perfect telescopes and violins are made, where the foreigner hesitating between two women always encounters a third, where cockfights degenerate into bloody brawls among the bettors.

於是他到了Isidora，在这里，每一个建筑物都有螺旋状的阶梯、阶梯上又镶嵌了螺旋状的贝壳；完美的望远镜和小提琴也从这个城市中出产。在这里，当一个旅人厌倦了两个女人时，总会出现第三个女人供他选择；在这里，斗鸡比赛中总会出现赌徒的流血斗殴。

The results show that the precooling time of the probe is shortened significantly with the help of the vapor liquid separator, and decreases with the driven pressure. With the helical coiled wire and the helical mesh, significant thermal Oscillation corresponding the density-wave is observed in the precooling time. The average heat transfer coefficient enhances 1.5 times with the mentioned heat transfer enhancement techniques, and the temperature of the 2.5 min cryoprobe surface can reach -160℃ in 17℃ brine within 10 min.

结果表明：使用了快速预冷汽液分离器后，探针预冷时间大大缩短，并随驱动压力增大而减小；加入螺旋丝和螺旋丝网后，在预冷阶段出现明显的热力振荡，并伴有密度波振荡，平均换热系数为原来的1.5倍，在17℃生理盐水中10min时2.5min探针表面温度最低可达－160℃，大大提高了探针的冷却性能。

If you have a long face, the perm must be worked to ensure volume on the side but never on the top. Some women try out spiral curls with curling irons at home. For this, you need to be equipped with spiral curlers or rods and hair perm lotions .

如果你的脸比较长，就要确认发量应主要集中在两侧而不是头顶；有些女士尝试在家用烫发棒制作螺旋状弯曲的发型，这时你需要配备螺旋状卷发夹子或卷杠以及烫发水。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
