4DRG was co-culture with sciatic nerve segment in 10鸖 DMEM;the axons were longer and surround the sciatic nerve segment which was regard as anew evidence for chemotropism.

结果：(1)在无血清条件下单独培养的DRG，背根神经节的轴突数目众多，外形纤细弯曲，不成束，并且施万细胞和成纤维细胞稀少，所以可以排除两者对轴突生长的影响，为观察来源于变性坐骨神经段的可溶性因子对轴突生长的作用提供了有利条件；(2)在无血清条件下DRG和变性坐骨神经段联合培养，①先单独培养DRG，4天后待神经元轴突长出，再与坐骨神经段联合培养，观察到神经元的轴突数目减少，外形挺直，部分轴突之间相互粘附成束；②变性坐骨神经段和DRG同时联合培养，神经元的轴突数目明显减少，外形粗壮，轴突之间相互粘附成束；(3)有血清条件下单独培养DRG，轴突数目较多，外形挺直，长短不一，部分神经元的轴突之间相互粘附，施万细胞和成纤维细胞数目众多，观察到的轴突生长情况受到施万细胞和成纤维细胞的直接或者间接的影响。

The distribution of the qualitative characters The performance of the 39 chief qualitative characters were observed and recorded,according to the test method of morphological characters in the .The results of distribution proportion of each character in cultivars group showed that the distribution of 32 characters(number of ray flower rings,floret curliness,shape of leaf base,size of stipule and so on) were very asymmetrical with near or above 70%cultivars concentrated upon one or two performance, however,the distribution of the other 7 characters(floret type,surface color of outer floret,back color of outer floret,color of disc floret,claw in base of sinus between lateral lobes,stem erectness and stem color) in the cultivars group were relatively symmetrical.

质量性状分布参照《菊花DUS测试指南》的形态性状测试方法，观察记录大菊39个主要质量性状的表现，计算各性状的表现式样在品种群内的分布比例，结果显示舌状花的重瓣性、花瓣曲反状况、叶片基部性状、托叶大小等32个性状的表现式样在品种群内分布极不均匀，接近或超过70%的品种集中在性状的1种或2种表现式样中；而花瓣形状、外花瓣表面色、外花瓣背面色、花中心部颜色、叶裂刻基部有无突起、茎的曲直性和茎色等7个性状的表现式样在品种群内的分布则相对均匀。4。

Not sibylline but clear, empty weather; of the eight kinds of sky it was the milk-paled potion most like a cup of coffee she poured past full in such a way as to show herself how good she was, how the liquid lolled just over the white cup's rim, just so the instant before an apology, until the surface broke and color seeming singular though made of mix came sweetly over the sides after which she could never think of herself as perfect again, falling deeper into bright degradation as one falls down a well with great relief, forgetting on the way how as a child she make her father stop at every corner so she could sketch in her daybook the cross street and what stores were where, using his back for a desk.

不神秘且晴朗空寂的天气；在八类天象中它属奶白一族最似她倒得溢出的一杯咖啡，她倒成那样摆显给自己看她如何有能耐，那液体如何恰好溢过白杯的杯沿，就在道歉要出口前打住，直至表面裂开那看似单一实则混成的色彩顺着杯沿甜蜜地流下，那以后她再也无法认为自己是完美的了，却在辉煌的降格中陷落得更深，如同一个人带着极大的解脱感落入一口井，在下落时忘却了小时候她让父亲在每一个街角停下，如此她能以父亲的背当桌在本子上描画对过的街道和店铺。

金色的羊毛希腊北部国王阿塔玛斯有两个孩子，法瑞克斯和赫勒。当国王离开第一个妻子和一个名叫伊诺的坏女人结婚后，两个孩子受到后母残忍虐待，整个王国也受到毁灭性瘟疫的侵袭。伊诺在爱轻信的丈夫耳边进谗言，终于使国王相信：他的儿子法瑞克斯是这次灾害的罪魁祸首，并要将他献给宙斯以结束瘟疫。可怜的孩子被推上了祭坛，将要被处死。正在此时，上帝派了一只浑身上下长着金色羊毛的公羊来将两个孩子驮在背上带走了。当他们飞过隔开欧洲和亚洲的海峡时，赫勒由于看到浩瀚的海洋而头晕目眩，最终掉进大海淹死了。这片海洋古时候的名称叫赫勒之海，赫勒拉旁海峡便由此而来。金色公羊驮着法瑞克斯继续向前飞去，来到了黑海东岸的科尔契斯。在那里，法瑞克斯将公羊献给了宙斯；而将金羊毛送给了埃厄忒斯国王。国王将羊毛钉在一棵圣树上，并派了一条不睡觉的龙负责看护。

It points out: a rational arrangement of supplementary cathode can greatly uniformize the handsaw temperature duo to its double actions of redistributing heat source and reducing thermal radiation; less shield layers at the top of the furnace leads to more uniform horizontal temperature distribution. The horizontal plate between two rows of handsaws can enhance the radiative heat transfer at the center place, and therefore can reduce the temperature difference along both horizontal and vertical directions.

指出：辅助阴极具有重新分配炉内的热源分布和隔热保温的双重作用，合理添加辅助阴极对改善料筐内温度场的均匀性具有重要的作用；在渗金属炉的顶部减少辐射屏层数，可以在保证竖直方向满足工艺要求的同时改善水平方向的温度场的均匀性；料筐的几何结构对温度场有重要影响，锯条背之间的距离以60毫米为好；减少料筐材料的发射率有利于局部控制料筐温度。

In one corner was a stagnant pool of water, surrounding an island of muck; there were several half-drowned fowls crowded together under a cart, among which was a miserable, crest-fallen cock, drenched out of ail life and spirit; his drooping tail matted, as it were, into a single feather, along which the water trickled from his hack; near the cart was a half- dozing cow, chewing her cud, and standing patiently to be rained on, with wreaths of vapour(5) rising from her reeking hide; a wall-eyed(6) horse, tired of the loneliness of the stable, was poking his spectral head out of a window, with the rain dripping on it from the eaves; an unhappy cur, chained to a dog-house hard by, uttered something every now and then between a bark and a yelp; a drab of a kitchen wench(7) tramped backwards and forwards through the yard in pat- tens, looking as sulky as the weather itself; everything, iq short, was comfortless and forlorn, excepting a crew of hardened ducks, assembled like boon companions round a puddle and making a riotous noise over their liquor.

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
