The core uses a data structure called USB Request Block , or URB ( defined in include / linux / usb . h ), to asynchronously manage data transfers between the host and the device .

这个核心使用一种叫做USBRequestBlock或URB（在include/linux/usb.h中定义）的数据结构，来异步地管理主机和设备之间的数据传输。

It introduced the way of development of USB video camera driver which is conformity with the Video for Linux principle , and it put forward some improvement ideas , such as double URB and double buffer , to improve collection speed .

介绍了在Linux系统下开发符合VideoforLinux标准的USB摄像头驱动的方法，并对该标准改进思路，配合双URB、双帧缓冲等方法，提高采集速度。

On the basis of quantitative reversion of pollution measurements by satellite , combining with green land distribution , green land statistics and meteorological data , a dynamic monitoring and research has been done to the particle pollution of the central urb in Shanghai by using GIS multifactor integrated analysis .

在卫星污染测值的定量反演基础上，结合绿地分布、绿地统计以及气象等资料，通过GIS多因子要素综合分析，对上海中心城区的颗粒物污染状况进行了动态监测和研究。
