The South China Sea (SCS) is one of the largest marginal seas in the western Pacific. Its northern part has the features of a passive continental margin. The studies of deep crustal structure in this
Based on remote sensing data and models, spatial distribution of the monthly euphotic depth in the East China Sea in 1998 has been obtained. The character of the seasonal changes of the euphotic depth
如何对付由于高潮时的水生状态与低潮时的气生状态高频率循环所导致的不同环境条件 ,是潮间带海藻的光合作用所面临的独特问题。对采自汕头沿岸的石莼 (Ulvalactuca)在水生和气生不同状态下光合作用对光照和温度的响应特性进行了测定 ,以探讨这种常见的潮间带绿藻在潮汐循环背景下的光合特性。在气生状态下 ,光饱和净光合速率 (Pmax)随气生暴露时间的变化模式可以很好地用三次方程进行描述 ,而温度影响
This paper introduces two steps to design a quantizer of H.261 CODEC: the first step is to implement the coarse quantizing through control algorithm for the buffers occupation ratio; the second step i
Computer vision systems have an impressive spread both for their practical application and for theoretical research. The common approach used in such systems consists of a good segmentation of moving
记者从日前在京开幕的第十届国际自动识别技术展览会上了解到,经过20多年的发展,我国自动识别技术的产业,已形成从终端设备到应用系统,乃至与信息化技术集成应用的系统行业解决方案,1000余家企业初步形成我国的自动识别技术产业链,并且发展了一批具有自主知识产权的软硬件产品。
