The detectable group, biotin-ε-aminocaproic acid N-hydroxysuccinimide ester, is attached to the remaining amino group. A series of multiamine compouds, i. e. ethylendiamine, 1, 6-hexandediamine, triethylenetetramine, tetraethylenepentamine, and synthetic polyarylamide are used inlabelling, it is found that linker arms and steric hindrance effect the detection sensitivity. The probes labeled by 1, 6-hexandediamine and triethylenetetramine can detect 0.1-0.5pg target DNA in dot blot hybridization, and their sensitivities are better than the others.

In this thesis, the resonance fluorescence spectra of a A-type three-level atom is calculated, which is driven by two bichromatic fields having the same difference of the frequency. In addition, the influence of the relative phase difference on the fluorescence spectra are considered. It is found that the fluorescence spectra of the atom are deeply depend on the relative difference and the appearance and cancellation of the fluorescence are obtained by changing the relative phase difference.

The paper studied the physiological characteristics of the leaves of Cotinus coggygria Royal Purple with different colors in autumn. Three kinds of leaf colors were selected to measure the contents of chlorophyll, anthocyanin, phenylalanin ammo-nialyase activity and the water content in the leaves. The results showed that the leaves exhibited red if it had lower chlorophyll content, higher activities of PAL and higher content of anthocyanin. The green leaves had higher chlorophyll content, lower activity of PAL, less content of anthocyanin.
