摘 要 该文采用氧瓶燃烧法测定了硫酸多糖911的硫含量，根据所测硫含量确定了硫酸多糖911的平均单体式量，然后在此基础上应用脱羧法对硫酸多糖911样品的含量进行了测定。

SDRAM is used as image storage, which can store many frames image data to provide the foundation for the correlation operation between frames. FIFO is a data buffer for real-time image. All of these make the image processing system simple design, decreasing the write-read time and solving the question of transmission and delay, and allowing the data processing and the data grabbing at the same time. The processed results can be output in 20ms, so the bandwidth of the C6000-based image processing system is improved.

系统采用SDRAM作为图像存储器，可以存储多帧图像数据，为实现帧相关运算奠定了基础，实时图像数据采用FIFO作为缓存，使系统设计简单，读取速度快，解决了数据传输的瓶径问题，同时也减少了传输延时，实现了对图像数据边采集边处理，减少了系统的滞后时间，当场给出电视脱靶量，提高了图像处理系统的带宽。

An anaerobic-aerobic intermittent CSTR process was used to decolorize mixed dye with E. coli NO3 strain at a hydraulic retention time of 32, 18, and 10 h. The color-removal efficiency was around 70 ~ 80%. Under steady operation for over 117 h, the total decolorization was 10900, 18200, and 7590 for HRT=32, 18, and 10 h, respectively. After repeated operation cycles, the decolorization rate of E. coli NO3 was always higher than the original cycle. This may be attributed to the acclimation effect since the E. coli NO3 cells were repeatedly exposed to the azo dye.

NO3於HRT = 10、18、32小时之条件下进行厌氧-好氧间歇式CSTR生物反应器褪色操作，褪色率可以达到7080﹪左右；在约117小时的稳定褪色操作下，总褪色量分别为10900、18200及7590，这显示NO3在长时间之间歇式CSTR褪色操作下，不但稳定且具有优异之褪色能力；若将一组好氧、厌氧步骤视为一个循环去探讨褪色率之变化，则可观察到随著循环次数增加其褪色率逐次上升，之后则明显下降，这与摇瓶重复批次实验相似之结果，也可以解释为驯养效应所导致。

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.
