价

Contracts may become unenforceable or rescindable for "failure of consideration" when the intended consideration is found to be worth less than expected, is damaged or destroyed, or performance is not made properly (as when the mechanic does not make the car run properly).

所谓对价，指的是当事人一方得到某种利益、权利或好处，另一方损失某种利益、权利或好处，从而使双方都收到好处。换言之，对价就是当事人间的一种&我给你是为了你给了我的关系&。

The tetravalence vanadium was found in V2O5 gel thin films by measuring the electrical resistance change of V2O5 gel thin films with temperature, ESCA and X-ray diffraction analysis. in this paper, from miniamount redox in melting V2O5 and crystal structure, the influencing mechanism of miniamount redox on changing valence of vanadium was analyzed and discussed in detail.

通过对V2O5凝胶薄膜试样的电阻随温度的变化测试和电子能谱和X射线衍射分析发现V2O5凝胶薄膜中有四价钒的存在，本文从V2O5熔体的微量氧化还原和晶体结构的角度分析讨论了微量氧化还原影响钒离子价态变化的机理。

Thus, SRB were likely to reduce sulfates to sulfides simultaneously with petroleum oxidization, and directly or indirectly reduce hexavalent uranium U to tetravalent uranium U to precipitate pitchblende.

于是，利用烃类作为生存的碳源，硫酸盐还原菌将硫酸盐还原的同时，直接或间接地把六价铀U还原成四价铀U，导致沥青铀矿形成。

In the case of a call, this is the highest underlier value achieved, so the call has a payoff equal to the greater of: zero or the difference between that highest value and the fixed strike.

一种是行使价在期权到期时才确定：看涨期权的行使价定为有效期内标的资产所触及的最低价格，看跌期权则定为有效期内所触及的最高价格。

In each category, semantic and syntactic valent models of verbs are generalized.

第三部分：对俄语三价动词的配价能力进行了全面分析。

The author modifies the principle in the past research,and proposes the valent of verbs from two methods of syntax and semantics.

在前辈时贤提出的动词配价的确定原则的基础上，我们从句法、语义两个角度提出了确定动词配价的原则和方法。

Currently, there is a lack of systemic and through study regarding Mo removal by zero valent iron, and little is known about the mechanism.

目前，有关零价铁去除水中钼尚缺少深入系统的研究，特别是有关零价铁对钼的去除机理还所知甚少。

The results showed: 1 RN didn't the leaf width,leaf long,leaf area,yield,productive value and average price of flue-cured tobacco,but had significant effect on grad composing,content of chemical component and the accumulation of N,K and Cl.Within limited rang of RN,the relations between yield,average price,yield of high grad tobacco,yield of low grad tobacco,nicotin,N,reducing sugar,Cl,amylum,volatile base and the quotient of ammonium would been described by significant quadratic polynomial,and the relations between K and the quotient of ammonium conformed to negative linear equation;2With a RN of 75%∶25%,the value of proportion of high and middle grad tobacco,content of nicotin,N,K,uptake of N and K/Cl were the highest,volatile base was lowest.

结果表明：1RN对烤烟的农艺性状、产量、产值、均价等没有明显影响，而对烤烟的等级结构、内在化学成分含量、氮、钾、氯的吸收量有着显著影响，可以用显著的二次多项式模型或直线相关方程描述产值、均价、上等烟产量、下等烟产量等经济性状以及烟碱、总氮、钾、还原糖、氯、淀粉、挥发碱等内在化学成分的含量与铵态氮份额之间的关系；2RN为75%∶25%时，中上等烟比例、烟碱、总氮、钾、钾氯比、氮吸收量最高，挥发碱含量最低。

Inhibition efficiency of these inh ibitors decrease with the increase of free valence of N atom; Otherwise inhibiti on efficiency increase with the increase of summation of free valence in pyridin e ring .

这些缓蚀剂随着N原子自由价的增大，缓蚀效率降低；而随着吡啶环自由价之和的增加，缓蚀效率提高。

And I've calculated with a dollar / mark of two point thirty-six sixty-five and a Swedish dollar of seven point thirty-nine eighty.

我是按照2.3665的美元／马克价和7.3980的瑞典克朗／美元价计算的。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
