In comparison with bugle shaped nozzle, bifurcated nozzle downward jet angle 45°, cow-nose nozzle and three-hole nozzle, in all, the last two are better than the former and bifurcated nozzle downward jet angle 45 is better than bugle shaped nozzle; Cow-nose nozzle is helpful for guaranteeing the product's quality, in order to protect jet flow from eroding the strand at narrow face, gain uniform temperature distribution at cross section and decrease heat flux, adding the block's width to 100 mm. Three-hole nozzle is advantageous to increase flux and casting speed, but should avoid weak shell thickness in the center broad. In the real production, setting the SEN's immersed depth or plugging the hole at the bottom can adjust the flow and temperature distribution in the mold.

对比喇叭形水口，双侧孔水口(45°)，牛鼻子水口和三孔水口，总的说来后两者优于前两者；而双侧孔水口(45°)又优于喇叭形水口；牛鼻子水口和三孔水口比较各有特点，前者对保证铸坯质量有利，为防止流股对窄面的冲击，增加挡块宽度到100 mm，可使结晶器横截面上温度分布更加均匀，降低窄面热负荷；后者对增加流量，提高拉速非常有利，但要防止中孔射流过强导致铸坯中心坯壳变薄，在实际生产中可通过控制水口浸入深度或塞住浸入式水口的底孔来调节结晶器中的流动与温度分布状态。

The wear on bottom of mill is heavier than on side. Main worn form on bottom of mill is diamond fallen of bond and side is broken diamond.

刀具底面的磨损比侧面严重，底面金刚石主要以脱落为主，侧面金刚石磨损以冲击破碎为主。

Then, military economical efficiency of different airport traffic zone is analyzed based on the cost-effect analysis theory. The conclusion shows that although the investment of steel fibred concrete airport traffic zone is most expensive, its military economical efficiency is most notable.

它显著地提高了混凝土的抗拉、抗弯、抗裂、抗冲击、抗疲劳和韧性、延性、抗磨性能，是具有良好塑性的新型建筑材料[1]。20世纪70年代以来，美、日、英、法、德等发达国家已将钢纤维混凝土应用于机场道面和公路路面。

This paper analyses three tendency of network pioneer poem,"Sensual Composition","Breakage" and "Ant- elevation"."Sensual Composition" give a hard shock on current poem which had a aged character, but it also interflows with the utility of commercial society."Breakage" brings a valiant tidal current in poem composition, also forms a wild style."Ant- elevation" lead poem to the ground, hoist the flag of criticizing social problem, but it can also fall poem into trap of politics.

论文重点分析了先锋诗学中出现的&肉身化&、&破坏性&、&崇低&等三大倾向，认为&肉身化&写作对当下诗歌写作中陈腐的&中老年&特征进行了一次重大冲击，但客观上也迎合了&消费社会&的功利性；&破坏性&力量带来了一股强悍的诗歌写作潮流，解构、反讽、审丑、怪诞等写作手法形成了一种粗暴的美学风格，但也引发了诗歌写作新一轮的戏噱和狂欢；&崇低&将诗歌写作再度引向&地面&，重举批判现实的大旗，拆解虚伪的假面，但其借助网络所强调的&政治性批判&和对写作&政治禁区&的突破正让它面临沦为意识形态工具的危险。

The sand slurry abrasion tester with vertical multi clamps is sensitive to the variations in sand slurry concentration, impact angle of wear surface, materials and their properties, but not sensitive to the experimentation time.

多头立式泥沙磨损试验机对泥沙浓度、冲击角和材料种类性质的变化敏感，对磨损时间不敏感，有良好的实验灵敏度，对材料的适用面宽。

He adjusted the screen for a closeup as the ship shook with another missile impact.

当船以另一种飞弹冲击摇动的时候，他为一个近面分析调整了萤幕。

The odontoid vertebra space in the model was divided into lattices and the stress area of the odontoid vertebra was identified by force loading and analyses. It was found that the structure of the stress concentration area was closely related to the development of split sections. Therefore,when the odontoid process is attacked by the external force along its vertical plane,its waist is likely to break and type II fracture occurs. And the break also possibly appears in its base,in this way,type HI fracture occurs.

确定其材料性质、单元类型并控制好网格划分精度后，通过力的加载与分析，找出枢椎的结构应力区，根据结构的应力集中区与其断裂时断裂面走向的密切关系，从而判断出当外部载荷沿齿突中性矢状面不同角度作用，即齿突受到来自其矢状面的外部冲击时，容易在齿突腰部发生断裂，形成枢椎齿突Ⅱ型骨折，也可能在基底部发生断裂，形成枢椎齿突Ⅲ型骨折。
