It can be seen form the results of the experiment that the method oftwo-wavelength pyrometry can be used to measure the rod-like cathode temperature.But this method has a big difficulty which is that it is difficult to separate the radiationflux due to cathode reflecting from the total radiation flux in the experiment.

在实验中，我们测出了不同情况下的阴极温度分布；实验结果显示，双波长高温测量方法能很好地测量棒状阴极的温度，但是双波长高温测量方法存在着一个的很大困难是：在实验中，很难将阴极表面反射的辐射通量从总的辐射通量中分离出来。

CBR system poses many features, such as, memory accumulation, quick index, march, learn and induction.

However,the combination of BA with IAA promoted thededifferentiation and redifferentiation,though the regeneration frequency differed in kindsof combinations,among which the combinations of 2.0-3.0 mg/l BA + 0.5 mg/l IAAproduced a highest differentiation frequency of 70％or so.

在仅添加了BA的分化培养基上，下胚轴脱分化和再分化都比较困难，而BA和IAA配合使用时却能很好地促进下胚轴的脱分化和再分化。不同BA和IAA配比组合中下胚轴的不定芽分化率存在差异，其中以BA2.0-3.0mg/l+IAA 0.5mg/l组合的不定芽分化率最高，均达到了70％左右。
