  1. We analyse the dispersion of stock returns and have the tests of serial correlation. the results show that the trading mechanism has a significant effect on a number of characteristics of stock returns. first, the distribution of open - to - open returns has greater variance than that of close - to - close returns. second. the serial correlation pattern is quite different in the two return series. the open - to - open returns have negative autocorrelation coefficient, but the close - to - close returns is positive. further, employing an arma ( 1, 1 ) model we find that in the opening. returns exhibit higher residual noise and stronger dependence on past returns, reflecting stronger deviations from the random - walk form of the market efficiency hypothesis

    主要表現為：一，開盤收益序列比收盤收益序列具有更大的方差。二，兩種收益序列的序列相關形式不同，開盤收益序列表現為負相關，而收盤收益序列表現為正相關。而且我們通過arma （ 1 ， 1 ）模型的進一步檢驗，發現開盤收益序列比收盤收益序列具有更大的殘差，更依賴于過去的收益序列，也更偏離於市場有效的隨機遊走形式的假設。
  2. In the paper, diffuse channel characteristics is studied, multiple dispersion and background noise is detailedly analyzed, based on which the network buildup and protocol structure are analyzed

    在通道研究的基礎上，分析了無線光局域網的組網原理和協議結構。為實現無線光室內組網提供了解決方案。
  3. Presently, in the design of the ventilation and heat dispersion of the cabin, only necessary wind quantity is considered simply, while detailed mode and efficiency of the ventilation and heat dispersion are not considered too. so maybe the resource is wasted by the equipment, while noise is increased and stealth ability is decreased

    目前，在機組艙通風散熱的設計中，只是簡單地考慮了散熱所需的風量，而沒有考慮通風散熱的具體方式和效率，這不但造成了整個裝備對資源的浪費，同時還增加了機組艙的噪聲和降低了機組艙的隱身能力。
  4. Melp vocoders utilize mixed pulse and noise as the excitation to elimate the buzzes in traditional lpc vocoders, and add a jitter voicing state to overcome the tonal noise. parameters " interpolation, adaptive spectrum enhancement and pulse dispersion also are adopted to improve the continuity. the synthetic speech of melp vocoders sound much more natural and perceivable than the traditional vocoders "

    Melp聲碼器採用混合脈沖和噪聲激勵解決了經典lpc的嗡嗡聲的問題；引入了抖動濁音狀態以克服音調噪聲；利用參數插值、脈沖散布和自適應譜增強等措施提高合成語音的自然度和可懂度；此外還採用了多帶激勵，使其具有了比較強的抗背景噪聲的性能。
