查询词典 strength-testing

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。

Because the strength of springwood was very low, the strength of board which included more springwood was low. The main reason why there was no difference in wet compressing shear strength between quarter-sawn board and flat-sawn board was that quarter-sawn board had a lot of pits on radial cell wall and in flat-sawn board xylary rays were transversely cut and left a lot of pores which provided a kind of tunnels for water.

造成柞木径切板的反复煮沸压缩剪切强度与弦切板的反复煮沸压缩剪切强度没有显著性差别的主要原因是柞木细胞壁径面上的纹孔很多，而弦面上的木射线在经刨削后是横断的，留下许多孔隙，这使得弦径向均有成为水分通道的孔隙，造成柞木径切板的反复煮沸压缩剪切强度与弦切板没有显著性差别。

The comparative investigation of the characteristics of deformation and AE were conducted and the results are presented as followed: 1. The characteristics of rock AE are correlated to the strength, joints, cracks, and the size and hardness of crystalline grain. 2. The sequence of AE can be divided into four phases: beginning phase, tempestuousness phase, drop phase and dreariness phase. The loss and the duration of the phases are correlated to the rock character and flaws in the rock. 3. The AE rate characteristics are not almost concordant with the AE energy rate. 4. Besides the homogeneity, the strength of rock contributes the activity of AE. The higher the strength is, the lower the activity is. 5. There is a dreariness phase before the failure of most kinds of rock. 6. Whether the precursor is obvious is correlated to rock the character, and the precursor of AE rate is more apparent than the precursor of AE energy rate comparatively.
