动态随机存取存储器

RAM can be classified as Static RAM and Dynamic random access memory.

内存可分为静态存储器和动态随机存取记忆体。

The high capacity synchronous dynamic random access memory controlled by FPGA is used as the frame buffer of image data, thus solving the problems of the capacity and the speed in high resolution image data acquisition.

该方案中，由FPGA控制的高速大容量同步动态随机存储器作为图像数据的帧存，解决了高分辨率图像采集中容量和速度上的问题，SDRAM分时供FPGA和DSP访问的机制提高了数据存取的效率。

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。
