The intensity distribution of waves affecting on mudflats in Lianyungang, at conditions of tidal up-downs on water levels, is determined in this paper.

弄清在宽阔淤泥浅滩上破波作用历时及波浪动力的分布对理解淤泥质海岸的沉积和地貌分带性是重要的。

Based on the results of the theory analysis and computer simulation of ratrace, Waveguide-to-Microstrip Probe Transitions, DGS lowpass filter, the structure was designed and manufacture was made.

在对所用到的功率混合电路，波导－微带探针过渡，以及DGS低通滤波器进行理论分析、计算、和计算机仿真的基础上，制作混频器，并对设计结果进行了测试验证。

Large measurement range is obtained with double sideband modulation at 25 MHz.

而大测量范围则来自双边带调制的25MHz波。

Many later encounters with the Bohemian chef, with art professors and stonemasons, are the stuff of his later novels. A boy with a tin drum, who bursts in to a room in Switzerland in about 1952, becomes Oskar in his most successful work.

后来多次提及的波西米亚厨师、艺术教授和琢石工艺都是格拉斯小说中的事物。1952年，瑞士有一个带着铁皮鼓的男孩冲进一个房间，成为了他最成功的小说中的人物。

A new fast algorithm for continuous wavelet transform was proposed, aiming at improving the large computational complexity of CWT.

针对连续小波变换(Continuous wavelet transform， CWT)计算量较大的问题，提出了一种利用带通滤波实现CWT的快速算法。

The cool green precision of the canopy gave each house the aspect of an English country eatate arrayed with sycamores, a french chateau lined with Lombardy poplars or an ante-bellum Southern mansion entered through a corridor of live oaks.

树冠的绿荫如伞盖般，给底下各家各户带去丝丝凉爽，正如英伦诸家那排列的梧桐树，法兰西别墅旁伫立的拉波德白杨或是南北战争钱南部大楼周围走廊般的栎树林。

A relativistic Cherenkov source with slow wave system consisting of modified photonic band-gap cells is proposed and investigated.

提出了一种变态光子带隙结构，研究了由这种结构构成的周期慢波系统的Cherenkov辐射源的特性。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
