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 shoot formation rate of IBA induced PLBs was high, no matter they were cultured on yam bean or potato homogenate containing media. The 1/4 diluted MS basal salt medium had the best root induction and growth rate. Root cutting affected plantlet height and the number of shoot. However it had no significant influence on root length and number of root.

发根试验中探讨培养基中MS基本盐浓及继代培养时进根处对小苗发根生长之影响，结果显示含有1/4MS基本盐浓之培养基发根最高，而继代时之根处，会影响组培苗地上部之苗长及定芽，但对地下部之根长及根影响并显著。

Results showed that NBPT mixed proportionally with urea increased the soybean root vigor, root nodule number and weight, the root nitrogen fixation activity,and therefore the root growth was increased by a high content of N in the soybean plant.

结果表明，NBPT提高了大豆整个生长期的根系活力，对根瘤固氮酶活性有促进作用，根瘤数量和重量都有增加，因而大豆植株的含氮量也随之增加，根系生长得到促进。

In this study, NBPT mixed proportionally with urea and NBPT without urea were applied to the soybean plants to analyze the effect of NBPT on the soybean root growth in root vigor, root nodule number and weight, and the activity of nitrogen fixation of root nodule.

为探索利用NBPT提高大豆生长发育的途径，对施用NBPT的大豆，利用氧化还原法，乙炔还原法和凯氏定氮法分别测定了大豆根系活性，根瘤固氮活性和植株含氮量，并测定了大豆根瘤的数量和重量。

Root system is sturdy develop, give birth to root nodule closely, the errant bud on its root recovery capability is strong, can make root system spreads to horizontal way.

根系粗壮发达，密生根瘤，其根上的不定芽再生能力强，能使根系向水平方向蔓延。

This is the same as the "batching" tip from the work section above (as is the previous tip, and the next tip).

这和上面工作部分的批量处理的道理是一样的（这和前面的建议以及后面的建议是一致的）。

The detailed comparisons between the higher—order near tip solution and the well—known modified Prandtl field are also given in this paper.For the compressible materials, in order to satisfy the higher-order compatibility equation of the rate of deformation in the centered fan sector, which is a quite difficult problem unresolved in the previous studies, a particular term must be added to the expansions of the stress components in the regular logarithmic power series adopted by many researchers before. A higher-order near tip field with tangential velocity jump ahead of the crack tip is derived first, of which the dominant terms are the solution widely accepted.

对可压缩材料，本文首先采用非规则的对数幂级数渐近展开方法，克服了过去研究中存在的中心扇形区变形率协调方程的高次渐近式不能被满足的困难，并得到了一个切向速度在裂尖前方存在间断的高阶渐近解，该解的主项就是目前被广泛接受的关于可压缩材料的尖端场解。

From these result of the experiment, the dynamic modeling can be simulated effectively, when the move speed of tip is faster the shear force in the tip is bigger. In the lithography process the motion of tip influence by the pile up, it leads to the serration surface of the groove, is like the surface of actual material of the cutting process.

由加工成形与磨耗结果回馈，可有效做探针动态建模，并模拟出，当探针移动的速度越快时，针尖所承受的剪应力越大，并且在蚀刻过程中，针尖受表面堆积物的影响，导致沟槽表面类似锯齿形的蚀刻表面与实际加工之情形相似。

The findings indicate that, on the whole, the pattern of load transfer curves of adfreezing stress on a steel pipe pile stem and that of resistance stress on the pile tip are parabola and straight line, respectively; Due to the rheology effect, to different extent, adfreezing stress on the pile stem and resistance stress on the pile tip vary with time and relative displacement of pile-soil, respectively, and the settlement of pile tip varies with time tempestuously within 5 hours of loading, and then approximates to stability.

结果表明：模型钢管桩桩侧冻结力荷载传递函数曲线及桩端阻力荷载传递函数曲线其线状大致分别程抛物线及直线；由于流变效应的影响，桩侧冻结应力及端阻应力随时间有不同程度的变化；桩土相对位移和桩端下沉量开始5h内随时间变化较大，但加载5h后逐渐向稳定方向发展。

Hyphae, loaded with CTC under pH 6. 8 condition and then grown in pH 8. 0 medium for a little while to destroy the apical acidification, could gave very diffuse fluorescence images of CTC membrame bound Ca〓 and vermiform fluorescence spots due to mitochondrias under pH 6. 8 no longer were clearly distinquished, which implied that besides mitochondrias, other cellular organelles with Ca〓 also were stained with CTC. Thus mitochondrias are not the only one intracellular Ca〓 storage, endoplasmic reticulums and Golgi bodies in the same zone may be also the Ca〓 storages. But the extreme apical zone under 2μm of the growing hyphal tip was still almost devoid of stain under pH 8. 0.The CTC fluorescence was concentrated in the subapic zone beyond about 2μm from the tip and then gradually became lower behind about 40μm from the tip. These results did not support the hypothesis which suggested that the cell wall vesicles in the extreme apical zone were intracellular Ca〓 storages.

将菌丝在pH6.8条件下负载CTC，再置于pH8.0培养介质中短暂生长一会儿以消散菌丝顶端的酸化区域，则CTC膜结合Ca〓呈现弥散的荧光影像，在pH 6.8培养条件下显示的蠕虫状的线粒体荧光斑点不再能够清晰辨认，说明除了线粒体之外，还有其它含Ca〓细胞器，也被CTC染色，线粒体并不是细胞内唯一Ca〓库，还可能包括内质网、高尔基体等细胞器，但菌丝最顶端2μm以前的细胞壁泡囊区域不能被染色，最大荧光强度仍位于菌丝顶端2μm以后区域，约45μm以后荧光变弱，实验结果不支持细胞壁泡囊为菌丝胞内Ca〓库的假设。

When this condition occurs, inbound replication with the source partner is stopped on the destination domain controller and event ID 2042 is logged in the Directory Services event log.
