RESULTS: Olfactory bulb-derived olfactory ensheathing cells adhered to the wall at 24 hours. Olfactory mucosa-derived olfactory ensheathing cells adhered to the wall at 4-5 days. The morphology of the two kinds of cells was similar. Most of them were bipolar and spindle-shaped, and few were tripolar and flat.

结果：体外培养24 h嗅球源性嗅鞘细胞即可贴壁，而嗅黏膜源性嗅鞘细胞多在培养四五天后贴壁，两种来源的嗅鞘细胞形态相似，以双极或梭形细胞为主，少量为3极及多突起形多级细胞，同时夹杂扁平、煎鸡蛋形细胞。

It has been warranted through experiments and practical application that rare-earths-high-aluminium heat-resistant nodular iron has some intrinsic properties which are worthy of reconimandation, namely,that it will not scale after long periods of use at 1050-1100℃, will hardly break while being hammered into castings, runners or risers as the high-temperature tensile strength reaches 14-19 kg/mm2 at 800℃ or≥l3.3kg/mm2 at 900℃, with the room temperature strength close to HT 30-50 and the unnotched impact str...

本文介绍了稀土高铝耐热球墨铸铁的生产实践、化学成分；探讨了稀土作用及其用量和控制；论述了稀土和铝加入方式以及冷却速度对金相组织的影响；并对铸造工艺、铸件缺陷及分析、耐热性能及使用效果作了阐明。试验和使用证明：稀土高铝耐热球墨铸铁在1050～1100℃长时间工作不起氧化皮，热强度800℃时，14～19kg/mm~2，900℃时≥13.3kg/mm~2，室温强度近于HT30—54，a_k≈2～6kg·M/cm~2，锤击铸件或浇冒口，很难碎裂，并能机械加工。可以认为是以我国富产资源为原料，能用各种炉子熔炼、耐热和综合机械性能均较高硅、中硅中铝球铁、高铝片墨铸铁为高的一种耐热铸铁，也是镍铬系耐热材料较好的替代品。

Low-dose MSCT is sensitive and safe in investigating ureterolithiasis. High accuracy for the detection of ureterolithiasis is obtained and the radiation dose is significantly decreased by using low-dose MSCT performed.

低剂量螺旋CT平扫是一种敏感、安全的输尿管结石的检查方法，它诊断输尿管结石能够获得高准确率，并且明显降低对病人的放射剂量，延长了球管的使用寿命。

The gas flow field on the top of the discharged tube of cylindrical three phase cyclone with a vaned inlet and a direct current outlet which separates dusty droplet from the fume of boiler is measured with five hole probe.

使用五孔球探针对一种用于分离锅炉净化烟气中含尘液滴的直筒型导叶直流式三相旋流器排气管上部的气相流场进行了实验测定。

During a demonstration game, someone remarked to Morgan that the players seemed to be volleying the ball back and forth over the net, and perhaps "volleyball" would be a more descriptive name for the sport.

摩根最初给他的发明起的名字是&mintonette&，当地的一位教授很快将其定义为一种把球击过球网的游戏，于是，它最初的名字也就发生了改变。

Hollow microspheres are one kind of new material in nano- or micro- size with core-shell special structure whose core is hollow while the shell is bestrewed with pores.

中空微球是粒径为纳米到微米级的一种具有核-壳特殊结构、核心中空而壳上布满孔道的新型材料。

The game's popularity dwindled almost to zero during the 1700s, but in 1850, Charles Goodyear invented a vulcanization process for rubber, and during the 1850s, players began to experiment with using the bouncier rubber balls outdoors on grass.

这种运动在1700年，曾经销声匿迹，但是在1850年，Charles Goodyear 发明了一种硫化制造橡胶的工艺，在那时，球员们开始尝试在草坪上玩这种新式球。

The explosively formed projectile with fins for a cover charge structure by LS-DYNA software which four covers were conglutinated on the liner was studied by three-dimensional numerical simulation. The mechanism of forming EFP with fins was discussed based on the curves of velocity and pressure vs time of the liners. A contrastive analysis was carried out on the three kinds of liners which include big-cone shaped liner, imperfect-sphere shaped liner and arc-cone shaped liner.

采用LS-DYNA对在药型罩上粘附隔板结构形成带尾翼型爆炸成型弹丸(explosively formed projectile，EFP)进行三维数值模拟，从药型罩微元压跨速度和压力的角度初步探讨了形成尾翼型EFP的机理，对同一直径的大锥角型、球缺型和弧锥结合型药型罩形成的尾翼型EFP进行了对比分析，三种结构药型罩均能形成较为明显的尾翼，其中大锥角型药型罩得到的EFP速度最高。

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.
