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。

你可以将一头卷发披肩垂下，或将耳际的两缕秀发向后梳起，不然干脆高高地扎起一个马尾，青春活力无可阻挡；也可以在脑后盘成发髻，留出几缕鬓发随意飘垂，展现成熟女性的魅力；倘若做晚宴发型，微卷长发还是最好的"胚发"，可以做出各种美丽的花式发样。

Epidermal cells near the wound dedifferentiate and proliferate forming blastema and/or migrate to the wound plane forming a pre-epidermis consisting of several layers of stem cells covering the wound plane, which then re-differentiates further forming fully developed epidermis. Cells in the parietal peritoneum are also induced by injury to dedifferentiate into stem cells which then proliferate and migrate along the parietal peritoneum to the wound place forming a pre-peritoneum which re-differentiates into fully developed parietal peritoneum.

伤口愈合包括伤口闭合、顶端表皮层及体腔上皮的新生：创伤后的前4 d，残腕顶端的肌肉组织向伤口处迁移并重排使伤口闭合；创伤附近的表皮层细胞发生脱分化并增殖后迁移到创伤面形成由数层干细胞组成的前表皮层，之后进一步分化形成表皮层；而体腔上皮细胞在创伤诱导下也脱分化并增殖，然后沿体腔上皮迁移到创伤处形成"前体腔上皮"，经再分化形成新的体腔上皮。

Experimental results show the recognition rate of the method is 95%for a known expresser and 72% for a novel expresser. Aiming at the shortcomings of optical flow technique,two improved optical flow algorithms are presented.One way is to introduce forward and backword constraint eqution and Hessian matrix of optical flow equation is computed.The well- posedness of each point of local neighbourhood is examined and the weight of Lucas-Kanade's method is defined as the reciprocal of the conditioning number of its Hessian Matrix.

3针对传统光流法的缺点，分别提出了两种不同的改进方法：其一为引入前向-后向光流方程，计算其Hessian矩阵，把Hessian矩阵条件数的倒数作为Lucas-Kanade光流法的加权阵，可有效消除局部邻域中不可靠约束点，同时提高基本约束方程解的稳定性；其二为针对传统光流法只适用于刚体运动的特点，在扩展约束光流方程的基础上引入了div-curl样条函数作为扩展光流约束方程的附加约束条件，给出了一阶和二阶div-curl样条约束下光流的数值解。

An appalling plash within two yards of him was followed by a loud, rushing sound, diminuendo, which seemed to travel back through the air to the fort and died in an explosion which stirred the very river to its deeps!

距离他两码的位置发出可怕的激溅声，随后响亮急速的声音渐渐微弱，声音似乎是向后穿过天空到达堡垒并在爆炸声后平息，它的威力足以震惊整条河。

If the company and the dissentient shareholders fail to agree the price within 30 days of the fair value offer, then within 20 days of the expiry of the negotiation period the company must apply to the Grand Court to determine the fair value of the shares held by all dissentient shareholders who have served a notice of dissent and who have not agreed the fair value with the company.

假如于出价后的30天内，公司与持异议股东仍未能就公平价值达成协议，那么于商议期届满后的20天内，公司必须向大法院提出申请，要求由大法院来为所有送达了异议通知书，且未能与公司就公平价值达成协议的持异议股东所持有的股份厘定其公平价值。

Through a special arrangement of baffles in the stripper, the downflow back mixing of oil gases is reduced, and the influence of stripping gas on the separation efficiency is minimized. More than 99% of separation efficiency can still be achieved.

通过汽提器的特殊结构布置，减少了反应后油气的向下返混，并最大限度地降低了汽提对粗旋分离效率的影响，使引入汽提后的分离效率仍可保持在99%以上。

They share many similar or the same featutes with Archaeopteryx or other primitive birds, such as: U-shaped furcula, uncinate process, laterally facing glenoid of shoulder girdle, comparatively long forelimb, large semilunate carple, retroverted pubis, ascending process of astragalus, and "modern feathers"with rachis and barbs etc.

奔龙类是一类较为特殊的手盗龙类，它具有许多与始祖鸟Archaeopteryx甚至其它早期鸟类相似或接近的特征，主要表现在：叉骨U形与始祖鸟和孔子鸟类的相同，背肋钩状突在孔子鸟类和个别反鸟类中也存在，肩臼窝绝大部分指向侧方类似于始祖鸟，肩胛骨与乌喙骨间的夹角非常接近90°也和始祖鸟的相似，前肢从比例上讲显得较长，大的半月形腕骨使肘部能向侧方折过来，耻骨伸向后下方，距骨上升突与原始鸟类中的为同源结构，羽毛已有显著的分化且具备了现代羽毛的基本结构等等。

The main results were summarized as follows: 1 With the increase of cooling rate, full recrystallization during cooling became difficult to take place and the decrease in dislocation density became slow so that dislocation density in austenite remains higher before phase transformation occurred. 2 Compared with undeformed samples, the CCT diagram under deform conditions has a similar shape, but its position shifts leftwards.

计算结果表明：1随着冷却速率增大，低碳钢热变形后的冷却过程中再结晶变得越来越困难，位错密度的下降变慢，导致在相变前奥氏体中保留着较大的变形存储能；2奥氏体在经历热变形后的CCT曲线与未变形条件相比，明显向左上方偏移。
