| 摘 要： | 采用ＪＨ－１８·８寡核苷酸探针检测了兰属４植物基因组ＤＮＡ中的酶切片段，获得了由１０－１１条分子杂交谱带组成的ＤＮＡ指纹图谱，结果表明：在４．０－２４．０Ｋｂ范围内，大红朱砂（Ａ）的谱带数为１０条，红蝉（ＢＢ）为１０条，Ａ×Ｂ→Ｆ１２Ｎ＝４０（Ｃ）为１１条，Ａ×Ｂ→Ｆ１２Ｎ＝８０（Ｄ）为１１条，ＪＨ－１２·８探针能与兰属植物基因组ＤＮＡ小的简单重复序列形成杂交分子，表明兰属４植物基因组中存在同源的ＤＮＡ片段，为进一步在分子水平上进行兰扈植物的遗传多样性和近缘种群间的遗传差异分析提供了一种简便方法。

| Abstract: | The energy levels of the local mode vibrations of the water molecule have been calculated by using the potential energy surface of the H2O molecule , and the local mode effect has been explained by using its potential energy surfaces . As stretching vibrational quantum number n exceed 4 , the local mode vibration has appeared in the vibrational spectra of the water molecule. |
