The results show: the strongest bond is the Al-Al bond in the segregated cell without containing vacancy, where the Al atomic covalence radius is greater than that of Li atom in the cell; while the strongest bond is the Al-Li bond in the segregated cell containing vacancy, and the Al atomic covalence radius in the cell is less than that of Li atom. Since the difference of electronagativity between the Al and Li atoms is obvious, it is inclined to formed the Al-Li segregated cell of short range order structure in the condition of vacancy present. The short range order structure containing vacancy is probably the embryo or precursor structure of the metastable phase δ′(Al3Li). Because the strongest covalent bond in the Al-Li-vacancy segregated cell in alloy formed in quenching is the main strength reason for supersaturated solid solution of alloy. The bond net of succeeding precipitation of δ′(Al3Li) has the picture of anisotropic Al-Al bonding and the bond intensity enhanced. Since the δ′(Al3Li) is coherence with matrix, the bond net strength is enhanced by the precipitation of δ′(Al3Li) and so strengthen the alloy.
计算结果表明:不包含空位的偏聚晶胞的键络最强键为Al—Al键,其中Al原子的共价半径较Li原子的共价半径要大;而含空位的偏聚晶胞的最强键为Al—Li键, Al原子的共价半径要比Li原子的共价半径要小;在空位存在的情况下,由于Al原子与Li原子的电负性相差明显,促使Al和Li原子结合,倾向形成Al-Li短程序结构偏聚区,这种含空位的短程序结构很可能就是δ′(Al3Li)亚稳相的前兆结构和生长胚胎;由于Al-Li-空位有序偏聚晶胞的Al—Li键络比基体键络要强许多,因此,淬火过程中合金生成的Al-Li-空位偏聚晶胞对合金过饱和固溶体起主要强化作用;后续析出的δ′(Al3Li)亚稳相键络各项异性显著,键络强度明显提高;由于Al3Li与基体共格,其大量均匀弥散析出起到提升基体整体键络强度,同样对合金产生强化作用。

The degree of integration had positive relations with the degree of career development, however, the conflict ratio had negative relations with the degree of career development, and the degree of differentiation had inconsistent relations with the degree of career development; in study two, the Primitivity type held lower degree of career development and the Control type possessed higher degree of career development as predicted by the theory, while the other types were somewhat vague in between.
建构系统之统整性与生涯感受、生涯信念、生涯认识、思考广度与生涯计画等变项呈现出同方向的互动关系,而冲突性则与上述变项有反向的关系,分化性与生涯发展程度的关系则较不一致。质化资料分析结果亦显示出在生涯建构系统两极端之原初型与笃行型有较明显的生涯发展特徵,前者的发展程度偏低,后者则偏高,但处於两极端中间之慎思型与明辨型的生涯发展程度较为混淆不清。

The results show that Sb addition can diminish the crystal grain, but the content of segregative phase at crystal boundary increases, and the current efficiency of material is low. Compared with Sb addition, Sn addition can also diminish the crystal grain, the current efficiency increases, the content of segregative phase at crystal boundary reduces, but diffusional corrosion of the anode surface is not uniform. The cooperation of Sb and Sn can prevent Si from segregating effectively and enhance the current efficiency obviously. At the same time, anode materials have preferable surface dissolution characteristics.
