In this paper, 1554 strains of bacteria were isolated from the soybean rhizophere in the different continuous systems. Those biocontrol bacteria were screened in vitro and in vivo. 6 strains of them had the better control efficacy. They exhibited the different antagonism to the pathogens of soybean root in vitro. The strains 18BR2-2 and 18BR9-1 showed a wide range of antagonism against Fusarium oxysporum, F. avenaoeum, F. solani and Rhizoctonia solani in vitro. The 6 strains exhibited different control efficacy to soybean root rot in greenhouse and in field. In greenhouse, they could decrease the degree of soybean disease significantly, and the control efficacy of 18BR2-2 was the best and can reach 45.90%. In theory, soybean treated by 18BR2-2 may postpone the days of outbreaking of disease for 6 days. The strain 18BR2-2 also promoted the growth of soybean seedling and, raising the soybean height for 11.24%, increasing dry weight for 40.91% and fresh weight for 35.27%.

The other 10 central lumbar disc herniation case s were chosen as control group with low back pain and sciatic nerve pain but cauda equina symptom.All 31 cases were treated by operation.Method of imaging analy sis:the CT foraminal and ruptured areas were measured by MAS-l computerized ima ging analysis system,then the rates of foraminal and ruptured area were calcula t ed.

图像分析方法：将CT断层扫描图像在MAS-1图像分析系统上作图像分析，在486计算机上分别计算出同一层面椎管和突出物的面积，再算出突出物所占同一层面椎管面积的百分率；结果显示31例疗效均满意。21例梗阻型平均随访1.5年，根性症状完全消失，肛门、会阴部症状3／4消失，1／4明显缓解，图像分析结果：21例有马尾神经受损表现者，其突出物占同一椎管截面积60.4%～75.8%，平均66.7%。

of imaging analy sis:the CT foraminal and ruptured areas were measured by MAS-l computerized ima ging analysis system,then the rates of foraminal and ruptured area were calcula t ed.Results showed that the nerve root pain disappeared in 21 obstructive disc cases besides the symptom of anus perineum disappeared in 3／4 and alleviated in 1／4 cases within 1.5 years follow-up.

Dig this tree, we saw the original bare bottom has grown a lot of hedgehogs as the root.

A Niu back to the house carefully weighing the Chrysanthemum Fairy "of Ju-song," which finally realize the meaning: of BAI Ju to transplant in March and April Qia head, and more water in May and June ground fertilization, in July August for good root, this September will be open to the chrysanthemum-like hydrangeas.

阿牛回到屋里仔细推敲菊花仙子的《种菊谣》，终于悟出了其中意思：种白菊要在三月移植，四月掐头，五月多浇水，六月勤施肥，七月八月护好根，这样九月就能开出绣球状的菊花。

When Mg(superscript 2+) concentration increased, the fresh weight and dry weight of maize sad soybean decreased ,but they both showed some adaptability The growth of radicles and seedlings in maize and soybean were obviously inhibited by Mg(superscript 2+) and atrophy and dysplasia phenomena appeared.

随着Mg(上标 2+)浓度升高，玉米和大豆的鲜重和干重降低，但均表现出一定的适应性。玉米和大豆幼根和幼苗生长受Mg(上标 2+)抑制明显，普遍表现出萎缩、发育不良现象。

AbstractObjectives1 Correlate bone mineral densityto vertebral compressive strengths.2 Consummate the technique for percutaneous polymethylmethacrylate vertebroplasty and observe the pattern of PMMA imaging distribution.3 Determine the strength and stiffness of osteoporotic with or without vertebroplasty with PMMA bone cement.4 Correlation of BMD,insertion torque and pull-out strengths of pedicle screws.5 Ascertain whether augmentation with PMMA bone cement can enhance pedicle screw fixation in the osteoporotic spine.6 Ascertain whether augmentation pedicle screw fixation with PMMA bone cement can enhance the stability of unstable thoracolurner burst fractures of osteoporotic spine.

The multi-blade cutting which exceeded two-blade occurred for the reason of matching among parameters of speed of rotation, forward velocity, and numbers of blades, and it could be avoided; different oblique angle would lead to different passing through distance of the blade, and it is equivalent to different blade thickness in cutting; different position of sugarcane to basecutter would influence on the stress of the stubble when being cut.

给出了甘蔗受到多刀切割和重复切割刀数的计算公式，出现多于两刀切割的现象主要是由于刀盘转速、收获机前进速度和刀片数之间的匹配问题，是可以避免的。刀片安装角度影响刀片切入甘蔗所经历的路程，并且相当于改变了实际切入甘蔗的刀片厚度。甘蔗和根切器的相对位置影响根茬与刀片之间的作用力。
