介绍了两种二维周期结构的准光滤波器的设计及其仿真结果。

Famines in Shaanxi history is characteristic of frequentness, graveness, regionality and upgradation, assuming a recurrent period of proximately 3, 7, 15, and 22 years. Hence an obvious period icity of 4 phases of high frequency.

陕西历史饥荒的发生频率具有频繁性、严重性、局部性、增长性；有着准 3年、7年、15年、2 2年发生周期，具有明显的阶段性，大约每 10 0年有 4个高发阶段。

Furthermore, the β angle is very close to 108° of the pentagons in the (010) plane of the Cr3 icosahedron.

首次在Al-Cr-Si三元合金系中发现了周期为1.24nm和3.72nm的两种稳定十次准晶。

We suggested that, in the last 130ka, the prominently lake expanding period i.e. the pan-lake period, probably have come into being at MIS5e、MIS5c、MIS5a、 MIS3c、MIS3a, corresponding to high summer solar radiation stages of middle and low latitude in northern Hemisphere, which were in phased with 20ka-cycle. MIS5e was the warmest and wettest stage of the last interglacial, and the other stages were the interstadial of the last interglacial.

对青藏高原及上述诸地区末次间冰期以来气候记录的对比分析揭示：末次间冰期以来，青藏高原湖泊淡化、湖面显著扩涨期，即泛湖期，可能对应于MIS5e、MIS5c、MIS5a、MIS3c、MIS3a，即末次间冰期各暖湿期，末次冰期间冰阶；其分别产生于北半球中、低纬度夏季高太阳辐射阶段，具有准20ka周期演化特征，夏季风降水是造成湖泊扩涨的控制因素。
