After shaping, in order to count, the abtained singal will access to the external interrupt of SCM, and will be deposited in the chip AT24C02 of serial CMOS E2PROM which is supported by transmission protocol of I2C bus and brownout protection. In order to facilitate future show, the measured data will be deposited into history.

获得的信号经整形后接入单片机的外部中断进行计数，并且将计数值存入支持I2C总线数据传送协议的串行CMOS E2PROM芯片AT24C02中进行存储和掉电保护，测得的数据均被存入历史记录，以方便日后查看。

After addressing, the bus master sends each byte of data to the memory and the memory generates an acknowledge condition.

处理后，总线主机发送的每个字节数据存储器和内存产生一个应答的条件。

Data transfer operations are protected by CRC codes; therefore, any bit changes induced by card insertion and removal can be detected by the SD bus master.

数据传送操作是通过 CRC 编码来保护的，因此，由拔插卡引起的任何位的变动将会被 SD 总线管理器侦测到。

First, in this system, advanced 16-bit microprocessor 80C196MC is used to sample signals from industry cense. This makes it impossible to have a higher speed in data processing. Second, a kind of Field Bus-CAN is applying to build whole system into a more reliable, advanced real-time control network.

其次，通过现场总线技术将整个系统组成网络，实现了节点之间数据共享，并且整个监控系统更加稳定可靠，现场控制性能更为出色。

During this clock cycle, the microprocessor reads the data off the system bus and stores it in one of its registers.

在这个时钟周期之内，微处理器从系统总线上读取数据，并存储到它的某个寄存器中。

CAN Bus is some sort of a serial data communication protocol .

CAN总线是一种多主串行数据通信协议。

The research of this paper is began with the analysis the geographic spatial character of the UPTN, and designs the UPTN data mode based on GIS. Then, based on the good exhibiting all kinds of topology of the UPTN, and combined with the technology evaluation standards of the UPTN, this paper builds the UPTN planning mathematic model, and puts forward the quantitative calculation of the UPTN evaluation standards based on GIS; brings forward the arithmetic of the optimal path of the UPTN based on the public traffic network storage structure; designs the bus lines grouping management model, and realizes the contradistinctive evaluation of the UPTN planning projects based on GIS.

论文研究的重点内容是从分析城市公交网络中地理空间实体的特征开始，设计基于GIS的城市公交网络数据模型，在有效表现公交网络拓扑关系的基础上，根据公交线网技术评价指标，建立基于GIS的公交线网规划的数学模型，并给出公交线网评价指标的GIS量化计算方法；提出以公交线网数据存储结构为基础的公交网络最优路径算法；设计公交线路分组管理模型，实现公交线网规划方案对比分析。

Design and realization of data acquisition system based on CAN bus.

基于CAN总线数据采集系统的设计与实现。

Lastly, this paper introduces the concept of data service bus, and explains its important role in system integration.

最后，引入数据服务总线的概念，对总线的作用进行了阐述。

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。
