The following statements are proved:. A is equivalent to a diagonal matrix if and only if A is similar to a diagonal matrix.. If R is an APT ring, then A can be uniquely diagonalized as diag{e1,..., en} and ei divides ei+1.. R is an APT ring if and only if R/I is an APT ring, where I is a nilpotent ideal of R.

本文证明了以下结果：A相抵于一对角阵当且仅当A相似于一对角阵；若R是一APT环，则A在相似变换之下可唯一地化为对角形diag{e1，…，en｝，这里ei整除ei+1；R是APT环当且仅当R/I是APT环，这里I是环R的一幂零理想。

The trait EI and objective measures of emotional ability scale scores loaded onto two separate factors indicating that future researchers need to base their choice of EI scale for preadolescent children on theoretical grounds a priori.

特质型EI分数和客观评定测验中的能力型EI中所得分数被纳入到两个独立因素，说明今后研究者要根据研究的理论背景由因及果，选择适用少年的EI量表。

Structures of seven compounds were elucidated mainly by the use of spectroscopic methods, especially by detailed analyses of 〓 and 〓 NMR spectra with the aid of 2D NMR spectroscopy including 〓 COSY,〓 COSY, HMQC, HMBC, COLOC, and MS techniques including EI-, CI-, SI-, ESI-MS and HR-EI-MS. Stereochemical structures of some of them were also determined on the basis of results of their NOEDS, NOESY and coupling relation.

利用现代的各种波谱学方法，特别是在确定未知化合物结构中起重要作用的各种NMR技术（-维〓、〓 NMR、DEPT、NOEDS和二维〓COSY、〓COSY、HMQC、HMBC、COLOC、NOESY谱等）和MS技术（EI-、CI-、SI-、ESI-MS及HR-EI-MS等），鉴定了这7个化合物的平面结构和部分立体结构。

ei：电子电离

摘要 N-二异丙基磷酰基(DIPP)氨基酸的快原子轰击(FAB)和电子电离(EI)质谱都有相似的丢失两分子丙烯和一分子甲酸的碎裂过程.在FAB中,连续失掉两个丙烯,然后脱去甲酸的过程较为有利;在EI中则主要为先脱去甲酸,随后失去丙烯,
