Although both of FDRMADS7 and FDRMADS8 wereexpressed in the root, they have different expression pattern.The transcripts of FDRMADS7 weredetected throughout the root,especially the expression in the root meristem was the highest.However,the expression of FDRMADS8 was mainly localized in elongation and mature rigion.No apparent expression signal was detected in the root cap, root meristem and pericycle cells.

虽然FDRMADS7和FDRMADS8都在根中表达，但它们在根中的表达模式也不相同：FDRMADS7在根中到处表达，尤以生长点处表达量最高；而FDRMADS8在伸长区和根毛区的皮层中有大量表达，在根冠，根尖分生区和根毛区的中柱鞘细胞中却无明显表达，暗示它们在根中行使的功能也不相同。

Besides,ten er- rors in the minimal primitive root table of ime number were ointed out.

证明了奇素数 p 的原根与 P~1的原根、p~1的原根与2p~1的原根之间的等价关系，并指出了素数最小原根表中的十处错误

Second,a new estimator called generalized rootpower estimator of regression coefficients in growth curve model is obtained.For the newestimator,its superiority over the LS estimator and the root power estimator,and its admissibilityare proved.Two methods,two kinds of arithmetic of choosing the generalized root powerparameters are introduced.A demonstrative practical example is provided.

对增长曲线模型中的回归系数矩阵提出了一种新的估计——广义根方估计，并证明了通过广义根方偏参数的适当选取可使得该估计在均方误差和均方误差矩阵的意义下优于已有的最小二乘估计估计和根方估计；及证明了广义根方估计是可容许估计；还给出了选取广义根方偏参数的两种方法、算法和应用实例。

It is interesting that cervical root avulsion is a relatively frequent cause of superficial siderosis of the CNS. It is possible that trauma to the nerve root damages the fine venous plexus within the root, or the medullary and radicular veins that run along the nerve root, resulting in a fragile vascular scar.

很有意思的是颈神经根撕脱也是相对比较常见的病因之一，可能因为神经根的创伤可损伤神经根处的静脉丛及沿着神经根走行的根静脉，导致脆性血管损伤形成疤痕，当屈伸颈部时因牵引而破裂出血。

Clean and check 1 slowly loosen the gland nut stuffing, packing the release of residual pressure of all components; 2 Remove all old packing, thoroughly clean axle / rod stuffing; 3 Check the shaft / bar have corrosion, dents, scratches or excessive wear; 4 Check whether there are other WATER POWER CONTROL VALVE parts burr, cracks, wear, they will reduce the packing life; 5 Check whether there is too much stuffing the gap, and the shaft / rod eccentric degree; 6 the replacement of defective parts larger; 7 Check the old packing, as BALANCING VALVES the basis of failure analysis to find the reasons for early failure of packing.

缓慢松开填料函的压盖螺母，释放盘根组件内所有的残余压力； 2）移去所有旧的盘根，彻底清洁轴/杆的填料函； 3）检查轴/杆是否有腐蚀、凹痕、划伤或过度磨损； 4）检查其他零件是否有毛刺、裂纹、磨损，它们会减少盘根的寿命； 5）检查填料函是否有过大的间隙，以及轴/杆的偏心程度； 6）更换有较大缺陷的零部件； 7）检查旧盘根，作为失效分析的依据，球阀以找到盘根早期失效的原因。

Methods: Fifty four teeth with 54 interacanal fractured instrument were endodontically treated using G-G bur with ultrasonic techinque under dental operating microsc. The unsuccess rates were calculated and analysed.

Vent were studied in this experiment based on scanner-based image analysis. The results showed that drought and AM inoculation had a large, significant effect on plant development. Biomass, total length, surface area, volume, number of root nodes, average diameter and fractal dimension of root system in Broussonetia papyrifera Vent decreased with the reduction of soil moisture, while they were increased by AM inoculation. Special root length in non-AM plants increased when soil moisture was reducing, but it was decreased by AM inoculation.

结果表明，土壤水分状况和接种菌根真菌对构树幼苗生物量积累产生了显著的影响；构树幼苗根系干重、总长度、表面积、体积、根节数目、根系平均直径和分形维数表现出随着土壤含水量的降低而降低，接种G.mosseae则使得该参数比同等水分条件下显著升高；未接种植株比根长SRL表现为随着土壤含水量的降低而升高，接种G.mosseae则降低了同等水分条件下构树幼苗的比根长；土壤水分和接种G.mosseae同样也对根节平均长度产生了影响。
