当前各湿法炼锌厂锌电解用电几乎都实行峰、谷、平,这是因为锌电解是用电大户,每产lt锌,直流电需3000—3200KWh,为避免和居民用电发生冲突,在用电高度集中地区,谷期一般都采用高电流密度,这样才能保证产量。另一个原因是谷期电价是峰期的三分之一,在谷期采用尽可能高的电流密度,可以大大降低用电成本。本文就高电流密度运行时的各措施做进一步阐述。  相似文献

针对OFDM信号的高峰均比问题,提出了一种将新型峰均比降低技术与数字预失真技术相结合的功率放大器线性化方案.其中,峰均比降低技术由传统的削峰技术、新型的削谷技术和闲置载波技术组成,信号的峰值和谷值同时被削去,峰均比得到最大程度的压缩.传统削峰技术用于降低信号的峰值;新型的削谷技术采用基于切线原理的矢量孔调整法,同时改变信号的幅度和相位,使得信号谷值变大;闲置载波技术用于减少削峰削谷处理所产生的带内和带外失真.实测结果表明,基于记忆多项式模型的数字预失真技术可以将功放输出信号的ACPR值优化10.5 dB,而在结合了新型峰均比降低技术之后,本方案可以将ACPR值进一步优化18.5 dB.该方案适用于未来4G通信系统.  相似文献

Relative merits of interval and entrainment conceptions of the internal clock were assessed within a common theoretical framework by 4 time-judgment experiments. The timing of tone onsets marking the beginning and ending of standard and comparison time intervals relative to a context rhythm were manipulated: onsets were on time, early, or late relative to the implied rhythm, and 2 distinct accuracy patterns emerged. A quadratic ending profile indicated best performance when the standard ended on time and worst performance when it was early or late, whereas a flat beginning profile (Experiments 1-3) indicated uniform performance for the 3 expectancy conditions. Only in Experiment 4, in which deviations from expected onset times were large, did significant effects of beginning times appear in time-discrimination thresholds and points of subjective equality. Findings are discussed in the context of theoretical assumptions about clock resetting, the representation of time, and independence of successive time intervals.

In June 1994 the summit crater of Nyiragongo volcano, located in the Great Lakes region of central Africa, began to fill with new lava, ending nearly 12 years of quiescence. An earlier eruption of the volcano in 1977 had culminated in the catastrophic draining of a lava lake through fissures in the crater wall, feeding highly mobile lava flows which reached the outskirts of Goma and killed more than 70 people. By July 1994, as many as 20,000 Hutu refugees were arriving in Goma every hour, only 18 km south from the summit of Nyiragongo. The exodus brought more than one million people to the camps near the town raising fears of a repeat of the 1977 eruption. This paper examines the role that satellite remote sensing could have played in surveillance of the volcano during this time, and demonstrates the potential for monitoring this and other volcanoes in the future. Images recorded by the spaceborne Advanced Very High Resolution Radiometer (AVHRR)--freely available over the Internet--provide semi-quantitative information on the activity of the volcano. The aim of this paper is to promote the wider use of readily available technologies.  相似文献
