A statistics in world range indicates that the Sr/Eu ratios in the peraluminous granites show similar variation trend to those in pegmatitic apatites. This paper suggests that the high Sr/Eu ratio (＞300) in apatites or peraluminous granites is due to the strong partition of Eu〓 into the aqueous fluid, and this ratio can be used as an excellent geochemical indicator of fluid exsolution from magmatic melts.

对世界范围内的过铝质花岗岩统计表明，过铝质岩浆岩的全岩样品中的Sr/Eu也呈现二歧变化，由此本文提出Sr/Eu比值是指示过铝质岩浆体系中岩浆流体相出溶的有效地球化学参数，大于300的Sr/Eu比值是Eu〓强烈分配进入流体相的地球化学标志。

The phase and group velocities of Lamb waves in the aluminum plate related to the frequency and the thickness of the plate because of the material characters. However, for the carbon fiber composite lamina, the situation was of difference, in which the velocities were with regarded to the frequency and thickness as well as the propagational direction and the fiber orientation.

输入铝板和碳纤维板的材料参数，即可得出铝板和碳纤维材料单层板中Lamb波的频散曲线，铝板为各向同性材料，其中的Lamb波相群速度只与频率板厚的乘积相关，碳纤维板为各向异性材料，其中的Lamb波相群速度不仅与频厚积有关，还与Lamb波传播方向、碳纤维的铺层方向相关。
