Each time after putting to (the instrument with the set of Yamshidi-Nadel provided by Kypho of America for injection of bone cement into the vertebrae; each putting could contain about 1.5 mL bone cement) inject bone cement into the vertebrae, the pressure P was not very high, with 500 kPa bar below for majority and the effect caused showed a significant statistical difference (P.01). Whereas, the pressure within the area of the vertebral P value was not high either, the majority was 10.00 Unit lower, which also led to the effects of significant difference (P.01). Both two states showed partial distribution. After making the statistical analysis to the casual two puttings between the first, second, third and fourth putting of each vertebrae, there existed the general differences. The differences were also found between other puttings (a.0083) on the statistics basis apart from between the first and second and between the third and fourth.

结果 每个椎体的椎体成形术均达到临床评价要求，每次推杆（美国Kypho公司提供标准椎体成形术中Yamshi-Nadel套系中推注骨水泥入椎体的器具，每具推杆可容纳骨水泥约1.5mL）推注骨水泥入椎体时所产生的椎体内的压力P不是很高，多数在0.50 bar以下，其所导致的效应具有显著的统计学差异(P.01)，而每次推杆推注骨水泥入椎体时的椎体内压力面积值P也不是很高，多数在10.00 Unit以下，其所导致的效应具有显著的统计学差异(P.01)，两者均呈偏态分布；而且，对每例椎体的第一、二、三、四杆之间两两予以统计学上的分析，在总体存在差异有统计学意义的基础上还发现除第一和二杆、第三和四杆之间外，其他各杆之间存在着差异(a.0083)。

The mechanisms for the differences among rice cultivars in Cd uptake and translocation There were significant differences in root oxidating abilities and soil redox potential between two typical rice cultivars, Shan you 63 and Wu yun jing 7, that are greatly different in Cd uptake from soil. The root oxidating abilities and soil Eh were accordant with Cd uptake for the cultivars. The difference between the two cultivars in Fe concentrations of root iron plaque was also significant. The cultivar with higher Fe concentrations in root iron plaque absorbed less Cd from soil.

四、水稻不同品种对镉吸收及分配存在差异的生理机理对土壤中Cd吸收能力差异很大的水稻不同品种间，根系氧化力和土壤氧化还原电位有显著差异，品种的根系氧化力和土壤氧化还原电位与该品种对Cd的吸收能力间有很好的一致性；水稻不同品种间，根表铁氧化膜的含铁量有显著差异，根表铁氧化膜含铁量高的品种，对土壤中Cd的吸收能力低；盆栽水分腾发量高及根系伤流液Cd浓度高的品种，吸收积累Cd的能力强。

The results were as follows. In the insert mutation genotypes, there was significant difference between body weights of 2 weeks aged BB and AB genotype (P.05), while there was no significant difference between AA and other genotypes.
