1) backswitching
背向反转效应
1.
Using the spontaneous domains backswitching and domain side-grown effects,we can explain the mechanism of the submicron domains evolution.
基于畴背向反转效应 ,利用外加短脉冲极化电场 ,通过对脉冲宽度、脉冲间隔以及脉冲个数的有效控制 ,在掺5mol%镁的铌酸锂晶体上得到周期为 1 7μm的均匀亚微米畴结构 ,其纵向深度为 30— 5 0 μm 。
2) back-switching
背向反转
1.
Based on back-switching reaction,domain-inverted velocity can be accurately controled by multi-impulse electric field,which can be used to fabricate MgO:LiNbO_3 with submicron uniform periodical structure.
研究了掺镁铌酸锂(MgO:LiNbO3)的极化特性及其畴壁运动的性质,通过调节多个脉冲外加电场来控制畴壁的运动,在背向反转效应作用下,反转畴发生劈裂,制备出均匀的掺镁铌酸锂亚微米周期畴结构,并分析探讨了掺镁铌酸锂亚微米结构的成因及其反转机理。
3) contrarian effect
反向效应
1.
We expand HS model s hypothesis, consider constrain of short sale and contrarian trader s effect, build Momentum and Contrarian Effect Model under Constrain of Short Sale, which clearly characterizes stock price s movement track affected by positive and negative news and directly describes momentum and contrarian effect s extent affected by news watchers and trend traders.
改进了HS模型的假设条件,增加了反向投资者行为偏差的影响,建立了考虑卖空限制的动量效应和反向效应模型。
2.
However ,the discovery of momentum effect and contrarian effect poses great challenge to the above hypothesis .
但动量效应和反向效应的发现对这个假设提出了有力的挑战,根据动量效应,投资者可以在买进前期表现好的股票的同时卖出表现差的股票来获得超额收益;而根据反向效应,投资者可以在卖出前期表现好的股票的同时买进表现差的股票来获得超额收益。
4) Crossover effect
反转效应
1.
The results replicated the crossover effect in landmark task as before, and manifested that greyscales have no crossover effect—the length factor have effect on the greyscales task as the landmark task, it only affects the bias magnitude, but not the error direction.
实验1验证了在速示迫选条件下,灰度标尺的长度因素不具有反转效应(crossover effect),虽然影响伪忽视的程度但是不改变其方向。
5) contrarian
[英]['kɔntrəriən] [美]['kɑntrərɪən]
反转效应
1.
This article studied the momentum and contrarian in Shanghai A stock market and Shenzhen A stock market using Jegadeesh and Titman method.
采用Jegadeesh等的研究方法,对沪深A股市场惯性效应和反转效应进行了检验和比较。
2.
In the paper,we used the Jegadeesh & Titman research method to explore the relationships between the anormalies of momentum & contrarian in the Shanghai A market and the following five variables: transaction volume,scale,profit ration,BM/PE and price.
采用Jegadeesh和Titman研究方法,分别检验了上海A股市场股票的交易量、规模、市盈率、BE/PE值、价格五因素与市场惯性效应和反转效应之间的关系。
3.
Therefore, the Shanghai and Shenzhen A-share stock markets are not effective market, momentum and contrarian anomalies exist.
我国沪深A股市场经过二十多年的发展,取得了很大成就,但与西方成熟股市相比,沪深A股市场仍存在许多问题,如中小投资者比例高、内幕交易和市场投机严重、金融产品单一及缺乏有效的避险工具等,因此我国沪深A股市场仍处于非有效市场水平,存在股价的惯性效应和反转效应异象。
6) contrarian effect
反转效应
1.
The Study on Momentum Effect and Contrarian Effect of Chinese Stock Market;
我国股票市场“惯性效应”与“反转效应”研究
2.
Based on a panel data of Chinese listed firms during 2000—2007,this paper empirically tests the re- lationship between the investors heterogeneity and return time-series predictability from momentum effect and contrarian effect.
本文以2000至2007年中国A股上市公司为研究样本,以中国股市的动量效应和反转效应为研究切入点,考察机构投资者与个人投资者的信息反应模式及其对股票收益的时间可预测性的影响。
3.
The contrarian effect of Shanghai Stock Exchange A - shares is investigated using a traditional financial index based on 180 A - shares sample data from 1999 to 2003.
基于1999年至2003年“上证”180家上市公司的A股数据,采用传统财务指标研究了“上证”A股市场的反转效应问题。
