突出地表現在:資本市場服務于國企轉制,造成上市公司股權結構存在缺陷,致使公司治理失效,上市公司缺乏持續發展的能力,公司經營風險轉化為市場的系統性風險;政府對資本市場準入的行政性壟斷,形成上市公司「殼」價值,虛高股票市場價格,引發系統性風險;金融市場分割,特別是貨幣市場資金缺乏進入資本市場的正常渠道,利率市場化水平低,影響金融資產定價,導致違規融資盛行,加大了市場風險;而由於市場監管不到位,以散戶為主的投資主體結構,則易導致機構大戶利用內幕信息操縱股價,機構投資者的發展不僅沒有成為穩定市場的力量,反而成為操縱市場的主力,加劇了市場波動。The specific research methods are listed : 1. matched filter taking the max ouput snr as the best rule correlates nonstop divided signal and divided echo to detect low snr target signal. then all one dimension divided correlation outs and done fft in portrait to leach interferential signal such as static or low rate mussy meaves, many pathway echo and so on and to take target ' s time difference and doppler frequency that combine parameters that target ' s direction taken from antenna and so on to implement target ' s orientation and tracking

第三部分包括第三至五章,第三章針對時點價格容易被控制和時點價格的波動性太大,增加了經理期權的風險等問題,研究採用期權期內的平均價格替代期權期末的時點價格計算經理股票期權收益,構建了幾何型平均價格期權定價公式,並與black ? scholes期權定價公式進行了定量對比分析,結果表明: ( 1 )採用期權期內平均價格替代期權期末時點價格有利於降低經理通過操縱股價的牟利機會,遏制經理操縱股價的動機; ( 2 )一般條件下,平均價格期權股票價格對經理的激勵作用優于標準期權; ( 3 )當臨近期權期末股價下跌時,平均價格期權能為經理提供適度保險; ( 4 )當期權期內,股票受大市持續走弱影響而下跌時,平均價格期權失去了激勵作用。The stability output second harmonic generation ( shg ) experiment results of single - longitudinal mode and multi - longitudinal mode with long cavity were explained reasonably with these rate equations. the high polarization of fundamental wave in the isotropic laser media nd : yag with type - i critical phase - matching lbo was studied with the rate equations including polarization of fundamental light. using the polarization function of lbo, a quartz full - wave plate was introduced into the cavity, a kind of birefringent filter by considering the combination of the polarization function of the type - i critical phase - matching doubling frequency crystal lbo and the quartz whole - wave plate was constructed
