In addition, laser Raman scattering and low temperature photoluminescence measurements are carried out, the GaSb-like LO mode, AlSb-like LO mode and the coupled mode between LO phonon and plasmon are observed. According to the dependence of the GaSb-like LO mode frequency on Al composition, an empirical formula was obtained for determining the Al composition.

用激光喇曼散射和低温光致发光研究了材料的光学性质，观察到了类GaSb的LO模和类AlSb的LO模以及LO声子与等离子体激元的耦合模L，并根据类GaSb的LO模随Al组分x的变化规律，得到一个计算Al组分的近似公式。

On the other hand, epidermal growth factor , calcium ionophore (A23187), kallikrein and tumor promoter (phorbol-12 myristate-13 acetate) have been shown to stimulate the synthesis of prostaglandins from the thymic epithelial cells.

在另一方面，表皮生长因子、钙离子载体（A〓3817）、激肽释放酶和肿瘤启动子却能促进胸腺内分泌上皮细胞中前列腺素的合成。

The stimulated Brillouin scattering and the effect of phonon loss in SBS in optical fiber communication systems are investigated.

对光纤通信系统中的受激布里渊散射以及声子损耗对SBS的影响进行了研究。

Further theoretical analysis demonstrated the lateral effective width of crescent-shaped quantum wires was 6nm within the regime of quantum size. With two-dimensional separated-confinement-heterostructures, the multi-quantum-wire laser arrays operated in pulsed condition (1kHz/1μs) at room temperature, and their pulse light outpower reached more than 115mW, which is the best among all quantum wire lasers reported previously.

这种多量子线激光器列阵具有二维分别限制的异质结构，并在室温脉冲（重复频率1kHz，脉宽1μs）下产生激射，光脉冲线性输出功率可达115mW以上，这是目前国际上各类量子线激光器的最好水平；子带间能隙最大为27meV，与室温下热离化能相当，优于目前国际上报道的同类量子线激光器的最好水平。

When operated as a bulldozer, a pair of endless track roller frames are free to oscillate up and down about a horizontal axis passing Lhrough the bulldozer's main frame for improved traction and grading characteristics, reduced stress on the tractor stmcturc, and a more comfortable ride for the operator.

操作时，作为一台推土机，一副没完没了的轨道滚子帧都可以自由摆动起来下降了约横轴及格lhrough推土机的主体框架，为提高牵引和等级特征，减少应激对拖拉机stmcturc ，更舒适游戏机经营者。
