The invention provides an anhydrous hydrogen fluoride production process; reaction raw materials fluorite powder and sulfate are mixed by an external mixer and enter into a converter with jacket; hot air with the temperature of 350 DEG C to 600 DEG C is fed in the jacket; the fluorite powder and the sulfate have chemical reaction and produce hydrogen fluoride; the produced hydrogen fluoride enters into a scrubber from a furnace header to be washed; the washed hydrogen fluoride enters into an intermediate tank from a condenser, and then receives distillation and degasification to prepare the finished product anhydrous hydrogen fluoride; solid residue is emitted from a furnace tail.

本发明提供一种无水氟化氢生产工艺，反应原料萤石粉及硫酸经外混器混合后进入带有夹套的转炉，向夹套内通入350～600℃的热风，萤石粉和硫酸在发生化学反应生成氟化氢，生成的氟化氢气体由炉头进入洗涤塔进行洗涤，洗涤后的氟化氢由冷凝器进入中间槽，然后经过精馏、脱气制得成品无水氟化氢；固体残渣由炉尾排出。

他是海神波塞冬漂亮的儿子。一天，他在森林中打猎，看到了阿尔特弥斯的仙女们——七颗明星。他如此爱慕她们的美丽，便追赶她们。困境中，美貌的仙女们向阿尔特弥斯求救。结果女神将她们都送入天空充当星座。后来奥利安爱上了另一少女墨洛珀。他鲁莽急躁地施暴于她。这激怒了少女的父亲俄诺皮耳国王。国王把他灌醉后，挖出了他的眼睛。随着"独眼巨人"大锤的敲响，他来到火神赫斐斯托斯跟前。火神派向导带他去太阳升起的东方。将眼球暴露于阳光后，他就恢复了视力，成了女神阿尔特弥斯永久的伴侣，并带着他的猎狗天狼跟随女神打猎。阿波罗并不赞成他们之间这种恋情。一天，阿波罗怂恿阿尔特弥斯向海中一移动的黑点射箭。她根本没想到自己是将箭瞄准奥利安。当看清黑点竟是在游泳的恋人奥利安的头时，阿尔特弥斯悲痛万分。因她无力使他起死回生，只好将他送入天空作一星座。他的猎狗天狼则蹲在他的身旁。

Forearm flexor origin from the medial epicondyle was exposed to allow tunneling of the long head tendon underneath the flexor origin.

方法切断胸大肌在肱骨的止点，在肱骨结节间沟顶端切断肱二头肌长头腱，然后向远端分离，显露至长头腱桡骨结节止点处，将前臂屈肌起点从肱骨内髁下方分离；将肱二头肌长头腱从前臂屈肌下方深面穿过，反折后穿过胸大肌止点，调整好张力再返回远端编结缝合。

Relatively speaking, the drawing for tube with fixed short plug technology would reduce the difference of the residual stress between inside and outside of the tube, and increases its uniformity.

你看，它正随冬风轻轻的舞蹈，一摇一摇，一上一下，它舞出了冬季凄凉的颜色，但缺少了一些热情；它正低着头向大地轻轻的诉说，诉说着对冬季的感受，语调中多了一丝的无奈；它正享受着冬雨的洗礼，洗礼后的它看上去更加的清新自然，但少了春秋季节的青春活力；它的头上还顶着冬雨留下的颗颗钻石，钻石让它变得美丽动人，但也增添了一些凄楚的神情。

Expose the nerve first at the posteromedial aspect of the distal end of the biceps femoris tendon and trace it distally to where it winds around the neck of the fibula. In this location the nerve is covered by the origin of the peroneus longus muscle. With the back of the knife blade toward the nerve, divide the thin slip of peroneus longus muscle bridging it. Then displace the nerve from its normal bed into an anterior position.

When doing the Dix-Hallpike on a flat table, it is often helpful to place a flat "boat" cushion under the persons back, to obtain head extension.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
