您要查找的是不是：
- Narrow waveguide after input section can effectively filter out the high modes which cause the ununiformity of Y-branches and has little influence on the length and excess loss of the device. 在输入波导后添加一段起模式过滤作用的窄波导结构,可以在对器件长度及损耗影响很小的情况下,有效滤除高阶模,减小干涉效应,改善器件输出的均匀性。
- The higher modes have shorter periods than the fundamental mode and, moreover, they have higher velocities. 高振型波比基阶振型波周期短，波速高。
- Interpretation of the relative importance of the higher modes is difficult since the higher frequencies tend to be closely spaced. 较高模态的相对重要性的说明也是困难的，因为较高的频率趋于挤在一起。
- The impact of piping to supports can excite higher eigenmode and results in an energy transfer from dominant lower modes into higher modes of vibration. 管道与支座的碰撞激发出系统的高阶振型，导致系统能量由低阶模态向高阶模态转移。
- Comparing with small tank, the sloshing in large tank includes not only fundamental mode but also higher modes and its fundamental period is much larger than that of small tank. 从与小体积罐的比较可以看出，大型储液罐的液面晃动不只是以基本振型为主，前几阶振型对液面晃动的贡献也比较显著，并且液面晃动的基本周期比小体积罐的大很多。
- A novel back-ward wave oscillator(BWO) with photonic band gap(PBG) structure is proposed. The PBG structure offers mode-confining and choosing mechanisms,restraining the lower modes and making the BWO operate at the higher modes. 提出了一种新型的具有光子晶体带隙(PBG)结构的返波振荡器(BWO),利用PBG禁带对BWO工作及输出微波模式进行调制,抑制低次模式,工作在高次模式。
- She skirted round the problem of the high cost. 她避而不谈巨额费用问题。
- Men and birds are fain of climbing high. 不论人还是鸟都愿意往高处攀。
- The bird sang high and clearly in the tree. 鸟儿在树上清脆地高歌。
- Goods of high quality are few and far between these days. 质地精美上乘的物品现在不多见。
- The medieval town was fortified with a high wall and a deep moat. 这座中世纪的城市周围建有城墙和护城河。
- Doctor Jianghai Xia in American Kansas University combined the fundamental mode with the higher modes, carried out the dispersion curve inversion by using the damping least square method, and Acquired preferable result. 美国Kansas大学夏江海博士将基模波和高模式波结合起来考虑，用阻尼最小二乘法进行瑞雷波的反演，获得了很好的效果。
- I set a high value on his advice. 我认为他的忠告很有价值。

- She enjoyed high prestige among the masses. 她在群众中享有很高威信。
- The dresses in the shop are priced high. 这家商店的衣服定价很高。
- The high salary reconciled me to living abroad. 我为获高薪也只好在国外生活。
- Trucks shuttled to and fro on the high ways. 车辆在高速公路上穿梭行驶。
- Although small QW has smaller optical confinement factor and smaller ratio of carriers injected into QW, it can provide higher mode gain because of its smaller mixing between valence bands. 小阱宽的量子阱虽然光学限制因子和载流子注入比例都较小，但由于其价带耦合小于宽量子阱，从而具有高的模式增益，说明量子阱的能带结构对其光学特性有决定性的作用。
- These rocks are awash at high tide. 这些礁石在涨潮时被海水淹没。
