对采用ZnCl2.渍法预处理的玉米芯进行实验，考察其预处理前后微观结构的变化；研究ZnCl2.量和温度对玉米芯热解特性和产物分布及生物油成分的影响。结果表明：ZnCl2.渍处理使玉米芯表面结构变疏松，产生片状结构；随着ZnCl2.量的增加，热解初始温度和最大热解失重速率对应温度向低温方向移动；当温度不变时，随着ZnCl2.渍量的增加，生物油产率降低，ZnCl2.量分数为1．69％时玉米芯在450℃下生物油产率高达47．39％；相同的ZnCl2.渍量下糠醛在生物油中相对峰面积随温度的升高而降低，而同温下ZnCl2.渍量越大，糠醛相对峰面积越高；在350℃和ZnCl2.量分数为5．89％的条件下，玉米芯热解获得的生物油中糠醛相对峰面积达到51．61％。

DQPSK modem has been chosen as the modem scheme in many mobile communication systems. A new signal processing technique of π/4-DQPSK modem based on software radio is discussed in this paper. Unlike many other software radio solutions to the subject, we choose a universal digital radio baseband processor operating as the co-processor of DSP. Only the core algorithms for signal processing are implemented with DSP. Thus the computation burden on DSP is reduced significantly. Compared with the traditional ones, the technique mentioned in this paper is more promising and attractive. It is extremely compact and power-efficient, which is often required by a mobile communication system. The implementation of baseband signal processing for π/4-DQPSK modem on this platform is illustrated in detail. Special emphases are laid on the architecture of the system and the algorithms used in the baseband signal processing. Finally, some experimental results are presented and the performances of the signal processing and compensation algorithms are evaluated through computer simulations.

ore deposits and a large number of ore occurrences cluster in Dexing ore field which is 2. km long and 12.km wide. The tectonic evolution, magmatism, as well as the metallogeny are controlled by the Northeast Jiangxi deep seated fracture belt (NJDFB). The source is believed to have been derived from the Meso-Neoproterozoic marine volcanism. The magmatic activity of Mesozoic I type granite could have provided the metal elements, thermal fluid, heat, and the space for ore forming processes. A unified geological model is proposed, which combines the tectonism, magmatism and metallogeny as the basic control of the giant metal mineralizations.

Rice is the staple food for more than half of the world population. The utilization of the wild abortive cytoplasmic male sterility (CMS) in 1970s has significantly raised rice yield potential. But the world's annual rice production will have to increase 70 percent over the next 30 years, to keep up with the demends of the growing population.
