查询词典 bond strength

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。

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).

Know to all, the way to bond disjunct advertising poster surfaces, we usually use mucilage, such as the 502 glue to join them together in one, but the means have a lot of disadvantages, such as:(1)Almost all of these kinds of bond are harmful on human health;(2)When work, the operation is slow and is not too satisfied in strength with the glue, to get a good strength, usually we must proceed a special handling, such as whet the surface to make the surface not smoothed, so it may cost more workers;(3)The air temperature may influence the stick strength, in low temperature environment, the bond effect maybe bad.

知道所有的方式，债券间断表面的广告海报，我们通常使用粘胶，如502胶加入他们在一起，但手段有很多缺点，如：（ 1 ）几乎所有这些种债券是有害于人类健康；（ 2 ）当工作，行动是缓慢的，而不是太满意的强度与胶水，得到良好的强度，通常我们必须特别处理，如刺激的表面，使表面不光滑，因此它可能花费更多的工人；（ 3 ）空气温度可能会影响到坚持的力量，在低温环境中，债券可能坏的影响。

It is found that from bond population calculation results, the bonding strength of Al—O bond of faces (011) and (011) of gibbsite are stronger than that of face (001). If the proportion of unfold of (001) surface is decreased and the proportion of unfold of (011) and (011) surfaces is increased to same possible extend, the bonding strength of Al—O bond of gibbsite would be more strong.

键布居分析结果表明，整体上氢氧化铝的(001)面的Al—O键的结合力不强，(011)和(110)面的Al—O键的平均键布居数较高，结合力较强；若小幅度降低(001)面的显露比例，并使(110)和(011)面较多显露，就有可能提高氢氧化铝表面的Al—O键的结合力。

It was found that the geometries of the studied materials were significantly affected by the ring size and intramolecular charge transfer. The HOMO level, LUMO level, and band gap of the studied model compounds were well controlled by the acceptor strength. However, the electronic properties of the studied polymer showed a significant different trend with the acceptor strength due to the geometrical transformation. The model compound of EDOT-TP and T-TP has the aromatic geometry but is transformed to the quinoid geometry for large intramolecular charge transfer. The small bond length alternation and large acceptor strength in the EDOT-BDP polymer also results in the smallest Eg of 0.7 eV among the studied polymers.

我们发现环的大小以及分子内电荷转移对结构有很大的影响，而小分子的HOMO、LUMO和能隙受到电子受体强度所控制，然而，高分子的电子特性与其构成分子却有明显不同的趋势，这主要是由於分子结构的转变，如小分子EDOT-TP以及T-TP因分子内电荷转移，使其高分子结构由aromatic转变成quinoid；而EDOT-BPP因其键长改变量小和良好的电子受体强度，使其能隙仅0.7个电子伏特。

解决的办法是，采用一块制卡和会员卡制作机的橡皮布代替树脂版，然后将药盒边缝拟粘合的部分在橡皮布相应位置揭掉一层，使揭掉的这层橡皮布不能让纸板上光，这个办法果真见效，药盒边缝不会上光，涂胶后粘结强度大大提高，而且还降低了用树脂版制版的成本，一举两得。
