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。

With Zhonghuang 35 as tested materials, the seed germination experiments of soybean were carried out by using 0.01, 0.10, 1.00 and 10.00 mg/L NAA. After culture for 7 d, the germination rates and the lengths of plumular axis, radicle as well as germ of soybean seeds were measured to compare the effects of NAA with different concn. on the plumular axis length and hypocotyls-radicle ratio when the soybean seeds germinated.

方法］以中黄35为供试材料，采用不同的NAA浓度(0.01、0.10、1.00、10.00 mg/L)对黄豆种子进行萌发培养试验，培养7 d后分别测量黄豆种子的萌发率以及胚轴、胚根和胚芽的长度，比较不同浓度的NAA对黄豆种子萌发时的胚轴长、胚轴胚根比的影响。

Bioassay results revealed: compared with alcohol control, extracts at parameter 1, 4, 7 stimulated the absolute germination rate and potential, radicle growth, plumular axis growth, fresh weight, dry weight at different levels; extracts at parameter 2, 3 stimulated the all germination index except radicle growth and axis growth; extracts at parameter 6 stimulated all but radicle growth and fresh weight; extract at parameter 8 stimulated only the germination potential.

生物检测结果显示，与酒精对照相比：萃取参数1、4和7等条件苦楝叶提取物对杉木种子绝对发芽率、绝对发芽势、胚根长、胚轴长、鲜重和干重等发芽指标均表现出不同程度的促进作用，萃取参数2和3等条件苦楝叶提取对除胚根和胚轴外的各发芽指标起促进作用，萃取参数5条件苦楝叶提取物对除鲜重和干重外的各发芽指标起促进作用，萃取参数6条件苦楝叶提取物对除胚根和鲜重外的各发芽指标起促进作用，而萃取参数8条件苦楝叶提取物仅对绝对发芽势起促进作用。

1 Contrast unstrengthened square reinforced concrete column and 10 reinforced concrete columns strengthened by circular steel jacket were tested under axial loading .

为研究圆形钢套管加固混凝土柱的基本力学性能，进行了1根未加固的普通钢筋混凝土柱和10根圆形钢套管加固的混凝土短柱在不同加固钢套管厚度及初始轴压比下轴心受压试验，初始轴力通过对未加固试件施加后张预应力来进行模拟；在试验研究的基础上，根据应变协调原则对加固后构件轴压承载力进行了数值分析。

To study the basic mechanical performance of reinforced concrete column strengthened by circular steel jacket,a set of experimental work was carried out.1 contrast unstrengthened square reinforced concrete column and 10 reinforced concrete columns strengthened by circular steel jacket were tested under axial loading.
