In chapter 1, the progress of the researches on cold atom physics and atom interferometers is reviewed.

本论文主要研究拉曼光的振幅与相位对原子干涉仪测量精度的影响。

At the same time, we studied the influence of quantum interference on the squeezing spectrum of the resonance fluorescence emitted from a V-type three-level atom and a -type four-level atom which are driven by coherent fields. We showed that quantum interference can greatly enhance squeezing in the components of phase quadratures at atomic frequency and change the squeezing spectrum .

同时，我们还研究了量子干涉对V型三能级和型四能级原子共振荧光压缩谱的影响，结果表明，量子干涉可显著加强原子跃迁频率分量的相位压缩效应和改变压缩谱的形状。

Wherein X represents a hydrocarbon group or hiydrocylhy-drocarbon group having 1 to 14 carbon atoms, a represents an integer of 1 to 6,b represents an integer of 1 to 5,R's represent a hydrogen atom,a halogen atom,a hydrocarbon group having 1 to 8 carbon atoms or an aryl,group independently from each other,and n represents an average number which is 1 to 10 and4,4'dihydroxybiphenyl,and having a softening point of not higher than 120℃,and not lower than 60℃.

其中x是一个油气组或hiydrocylhy-油气群有1至14个碳原子， a代表整数1到6，B代表整数1到5，R的是氢原子，卤素原子，烃类组有1至8个碳原子或一个芳，77独立于对方，而n是一个平均这个数字是1至10条和第4，4'dihydroxybiphenyl，并有软化点不高于120℃，不得低于60℃。

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。
