The structures were studied by IR and NMR. The absorption frequencies of the carbonyl group markedly depended on the coordination no. of the tin atom. The chem. shifts of 119Sn and 13C and the 1J(119Sn-13Sn) coupling constants of the compounds were determine Small structural changes around the tin atom were reflected in the 119Sn chem. shifts. For tributyltin arylcarboxylates, a relationship between 119Sn chem. shifts and Hammett constants of the para-substituents was found. The biol. activities of same compounds have been studied. They may be used as fungicides for fruit.

通过对它们的红外光谱、核磁共振谱(^1^3C， ^1^1^9Sn)的研究，表明羰基红外吸收频率与锡原子的配位数有密切关系，同样分子上的微小变化明显地表现在δ119Sn上，对位取代基苯甲酸酯的δ119Sn与苯环上取代基的Hammett常数之间存在良好的线性关系：δ119Sn=19.11σ+110.612 n=7，γ=0.9955着重研究了部分化合物在经济作物上的抗病原菌能力，结果表明，这是一类具有广谱性的有机锡化合物，抗菌活性优于对比药剂朴海因，接近或相当于多菌灵，它们同时具有较强的除草活性。

Inevitably then, some young turk proposes a revolutionary different model that explains the anomalies (such as, light is both wave and particle).

然后不可避免的，总有一些激进分子提出一个变革性的模型来解释异常事件。

Inevitably then, some young turk proposes a revolutionary different model that explains the anomalies (such as, light is both wave and particle).

这时，必然会有一些激进分子提出变革性的另类模型来解释异常事件。

Results Among 11 strains isolated from epidemic asthma-like pneumonia, 4 (36%) had extra six nucleotides inserted into the 3′end non-coding region of the F gene, whereas none of the F genes from 5 strains isolated from regular pneumonia had that insertion.

为了从分子基础来探讨RSV的致病性，本研究室对从不同地区、不同流行特征分离到的RSV进行了主要抗原结构蛋白的基因序列比较分析。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
