In order to miniaturization ofantenna, impedance complete compensate and matching optimization of electricallysmall antenna are brought forward, and this method is applied to the discage antennas.

从阻抗特性和辐射特性的实测数据表明,水加载单极振子天线的谐振频率能很好地向低端下移,局部水加载单极圆锥天线在保持原有宽频带特性的前提下,以较少的效率损失实现了较大范围向低频区扩展,即天线小型化,这将为短波短波波段天线进一步的小型化设计提供很好的思路。

It's believed that the future development of oxyfluoride glass ceramics will focus on the realization of unitization of materials, and the realization of high efficient short wavelength laser output, particularly in blue-green laser output.

认为氧氟微晶玻璃今后的发展重点将是实现材料的器件化,并实现高效率的短波长激光输出,尤其是蓝绿激光输出。

The oscillator strength and integrated emission section value of 〓H〓→〓I〓(521 nm) for Er〓 ions in visible wavelength is large, it means that Er〓 doped oxyfluoride glass-ceramics may be lase in short wavelength.

Er〓离子可见光波段的几个通道如〓H〓→〓I〓(521nm)有大的振子强度,积分发射截面和较高的荧光分支比,有可能实现短波长的激光输出。

The absorption spectrum center wavelength of dolomite is near 232 μm is shorter than 235 μm of limestone,and thus RBD7 and RBD8 can be employed effectively to identify dolomite and limestone,respectively. Felsic rocks show AlOH and Fe3+ absorption characteristics in the VNIRSWIR region,while the maficultramafic rocks show Fe2+ and Fe,MgOH absorption features,hence the use of different valence state of iron and secondary minerals can distinguish them:ASTER band2/band1 represent Fe3+ distribution,ASTER band2/band1 represent the Fe2+ distribution,RBD6 can estimate the AlOH mineral abundance. Psammitic/pelitic schist containing phengite,chlorite,stilpnomelane,as well as the weathered surface covered by clay minerals,exist characteristic absorption spectrum in the 221 μm(band 6),and has a high reflectance in 165 μm(band 4),while the blueschist/greenschist show high reflectance in the 221 μm(band 6),and it exit low reflectance in 165 μm(band 4),and blueschist/greenschist appear low ASTER band4/band6 ratio.

白云岩的CO2-3吸收谱带中心波长位于232〖KG*3〗μm,与灰岩的CO2-3 吸收谱带中心波长位置235 μm相比,具有向短波长方向移动的特点,据此可以利用RBD7、RBD8分别有效的识别白云岩和灰岩;长英质岩石显示AlOH和Fe3+ VNIRSWIR吸收特征,而基性超基性岩石显示Fe2+和Fe、MgOH特征,利用不同的铁价态和次要矿物可以区分它们:ASTER band2/band1代表了含Fe3+矿物分布信息、ASTER band5/band4代表了含Fe2+矿物分布信息、RBD6可以估计AlOH矿物的丰度;砂质/泥质片岩含较多的多硅白云母、绿泥石、黑硬绿泥石以及风化后表面覆盖的其它粘土矿物,在221 μm(band 6)存在有特征的吸收谱带,并且在165 μm(band 4)具有较高的反射率,而蓝片/绿片岩在221 μm(band 6)反射率较高,不具有明显特征吸收谱带,同时其在165 μm(band 4)反射率较低,因此蓝片/绿片岩ASTER band4/band6 比值低。

The light intensity to elicit the male's phototactic response was not significantly different in these three time periods. In terms of action spectrum, both male and females are more sensitive to ultraviolet light than to visible light, especially the spectral region between 330 and 340 nm for the females and 370 nm for the males.
