This shows that the Diderot and Rameau's Nephew in the community occurred in the level of two of the confrontation between the moral values, in Rameau's Nephew inside of the heart, is still contradictory, the confrontation of each other.

而拉摩的侄儿则恰恰相反。他代表的是一种变异的、趋恶的、以个人为中心、追求欲望满足的道德观念。两者之间经常发生着针锋相对的交锋。然而值得玩味的是，在二者的交锋中，扮演公正意识的狄德罗并没有取得胜利。在许多情况下，两人势均力敌，谁也说服不了谁；而在少数情况中，拉摩的侄儿反而占了上风。

It is vital to reduce the variation of Dracaena fragrans cv.massangeana and Dracaena fragrans cv.lindenii by preventing the differentiation from forming callus as well as the reduction or the prevention of callus redifferentiation.

避免脱分化形成愈伤组织以及减少或阻止愈伤组织再分化是减少金心也门铁和金边也门铁这类嵌合体品种发生变异的关键之一。

In the present experiment, the tender stems of Dracaena cambodiana were used as explants to establish a two-step tissue culture and regeneration system. The effects of types and concentrations of plant hormones on the induction of callus were studied. Based on these, the reactions of callus regeneration to different mutation-induced approaches (60Co irradiation, EMS and colchicines), the regeneration ability of the treated callus as well as the characters diversities (including the appearance traits and cytological observations) of the regeneration plants were investigated.

本试验以龙血树幼嫩茎段为材料，通过对龙血树幼嫩茎段两步培养法再生的研究，建立了龙血树幼嫩茎段离体再生体系，证明了愈伤组织的发生和激素种类与浓度的关系；并在此基础上研究了愈伤组织再生对不同人工诱变方法（60Co辐射、EMS、秋水仙素）的反应、被处理愈伤组织再生能力和再生植株性状多样性、以及再生植株不同生理角度的变异性，得到了2株变异株系。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.
