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。

Then, common imaging point gathers in offset domain were respectively extracted based on a single square root operator and double square root operator wave equation migration.

模型试算结果表明：与常规波动方程偏移方法相比，角度域叠加成像能够改善局部成像质量。

In order to solve the problem,We proposed a simple formula for computing paraxial travel time of single-way wave operator. The formula is based on the forward and inverse transform between time-space domain to frequency-wavenumber domain and from vector field to exponential manifold. The travel time are expressed as polynomials of the horizontal offset between the two points, and the single-square-root operator in frequency-wavenumber domain are expressed as polynomials of wavenumber. Coefficients of travel time polynomials and that of single-square-root operator are related each other and calculated by Lie algebraic integrand, exponential map and the saddle-point method.

针对此，基于时间空间域到频率波数域和向量场到指数流形上的正反变换，提出了计算单程波算子旁轴走时的简便公式，将走时表示成空间变量(地面点到地下相点的水平距离)的多项式，将频率波数域单平方根算子表示成波数的多项式，运用Lie代数积分、指数映射和鞍点法将走时多项式的系数与单平方根算子的系数联系起来，运用单平方根算子的系数计算走时多项式的系数。

Although translator has turned from being a crystal ball by which the original culture can unrestrainedly penetrate to another crystal ball by which the target culture can freely traverse, the translator's personal embodiment, in the process of cognitive act, are still absent in translation studies. Translators are still subjects without body or simply disembodied subjects.

译者虽然由原语文化可以自由穿透的玻璃球变成了译语文化可以自由穿越的玻璃球，但译者认知过程中的个体体验在翻译研究中依然缺席，译者依然仅仅是一个没有躯体体验的主体。

Chillingly, he claimed our technology is 'not nearly as sophisticated' as theirs and "had they been hostile", he warned 'we would be been gone by now'.

令人毛骨悚然的，他声称我们的技术是'并不那么复杂，像他们一样，和"如果他们敌意"，他警告说，'我们将现在已经过去了。
