查询词典 reciprocal function

This phenomenon suggests that the interactions between the nucleus and plastids are reciprocal: the development of plastid is controlled by the nuclei, on the other hand, certain nuclear genes by plastids.

这说明细胞核和质体之间的作用是相互的：质体的发育受细胞核的调控，另一方面，某些核基因的表达也受到质体的控制。

Polyembryonyoccurs in 〓 and 〓 caryopsis of cross SB-1 X Balilla(Balilla is non-polyembryony),and in 〓 caryopsis ofits reciprocal the polyembryony is observed but not in 〓caropsis.

在正交（SB-1 X 马来红，马来红不具多胚特性）〓及〓颖果中都出现了多胚苗，反交（马来红 X SB-1）的〓颖果未出现多胚苗，但其〓颖果观察到多胚苗，表明SB-1的多胚不是合子裂生产生的，而是胚囊的一种特殊性状。

The tolerance analysis on a matrix is highly complicated and has been widely discussed in recent years, especially on a positive reciprocal matrix for an evaluation decision.

矩阵上的容忍度分析是十分的复杂，然而近几年来却是广泛的讨论，特别是在决策评估的成对倒数矩阵上。

If a man''s household had been spoken of as his property we might have explained the expression as pointing to the extent of the Patria Potestas, but, as the interchange is reciprocal, we must allow that the form of speech caries us back to that primeval period in which property is owned by the family, and the family is governed by the citizen, so that the member of the community do not own their property and their family, but rather own their property through their family.

如果把一个人的"家庭"认为是他的财产，我们就不妨把这个用语解释为指"家父权"的范围，但是，由于这两个名词是可以相互交换的，我们必须承认，这样的说法把我们带回到了原始时代，当时财产是由家族所有，而家族则为公民所管理，因此社会的成员并不有其财产和其家族，而是通过其家族而有其财产的。
