内容简介本书以Xilinx公司的FPGA开发平台为基础，综合FPGA和无线通信技术两个方向，通过大量的FPGA开发实例，较为详尽地描述了无线通信中常用模块的原理和实现流程，包括数字信号处理基础、数字滤波器、多速率信号处理、数字调制与解调、信道编码、系统同步、自适应滤波算法、最佳接收机，以及WCDMA系统的关键技术。

Taking a general view of the paper, major innovative ideas and returns are as follows: The main innovative ideas are as follows: 1. The paper put forward the new idea that combine water-saving drilling with rotary percussion drilling creatively according to the present situation of water resource lack seriously and the background of implementation of state geological survey strategy. 2. The working principle of new designed system of water-saving hydraulic percussion device completely different from traditional hydraulic percussion device, the system can carry out rotary percussion drilling on the condition that no surface water be consumed, and achieve the purposes that saving surface water, cutting cost and improving drilling efficiency. 3. The design conception of steel ball percussion device is very novel, the percussion device is durable, with a simple structure, at the same time drilling efficiency would be improved highly and drilling cost would be reduced greatly when drill with the steel ball percussion device.

综观全文，论文的主要创新点及研究成果如下：主要创新点： 1、结合我国许多地区水资源严重短缺的现状以及国家实施地质大调查战略的背景，创造性地提出了&节水钻探&和&回转冲击钻进&结合起来的新思维； 2、设计出的节水型液动冲击器系统，其工作原理跳出了传统液动冲击器要消耗大量地表水的原理模式，在基本不消耗地表水的情况下便能实现回转冲击钻进，达到节约地表水、降低成本、提高钻探效率的目的； 3、设计的球体冲击器构思新颖，克服了同类产品冲击功传递效率低的弊端、且结构简单、经久耐用，可大幅度提高钻探效率、降低钻探成本。

Eating less meat was flavour of the month amongst the panellists as to how lifestyle choices should be curbed, along with the usual restrictions on flights, switching off lights and computers and using less heating. There is, Livingstone declared, 'no right to follow the Atkins diet', and consume 'excessive amounts' of meat.

当小组讨论成员谈到怎样约束地选择生活方式时，比如说减少坐飞机的次数、尽量少开灯、电脑和少用暖气，利文斯敦声明，没有遵循Atkins饮食习惯的权利，也没有消耗大量肉的习惯。

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。
