查询词典 return key

Properties of efficient portfolios and the efficient frontier to the model are systematically analyzed. Our main results concerning the properties are: every efficient portfolio can be solved by minimizing portfolio risk under a given level of portfolio return or by maximizing portfolio return under a given level of portfolio risk; on the efficient frontier, the risk is a convex and strictly increasing function of the return and the return is a concave and strictly increasing function of the risk; the utility function on the efficient frontier can be expressed as a quasi-concave function of the risk or the return if the investor's utility function is quasi-concave.

从理论上系统地对该模型下的有效投资组合和有效前沿的性质进行了分析，结果表明：每一个有效投资组合可通过在给定期望收益水平的条件下最小化投资组合风险来获得，或者在给定风险水平的条件下最大化期望投资组合收益来获得；在有效前沿上，风险是收益的严格单调递增凸函数，收益是风险的严格单调递增凹函数；当投资者的效用函数是拟凹函数时，则有效前沿上的效用可表达成风险或收益的拟凹函数。

Share the additionally a bit experience that plays me to make a station with everybody additionally, actually key word of the day on pop chart of dog of Baidu, search, week is very useful, it mirrorred near future netizen to be opposite the attention heat of what incident, what we need to do is the card that blends in these key word to us go among caption, but content is not certainly as pop chart content, but the content that can reflect key word, so to search engine, key word had, of content different those who let it believe us is to be achieved formerly, is not blind follow suit on the net duplicate, some key word it won't expire forever, we often blend in the key word of seniority to us inside the caption of all sorts of cards, as time passes, our forum it is dictionary of a keyword, I today Baidu spider assimilate to the word that is a deadbeat, so the heaven that my station is dish of all sorts of fastfood, name, to deadbeat that is greatest temptation.

另外跟大家分享下我做站的另外一点经验，其实百度、搜狗排行榜上的日、周关键字是很有用的，它反映了近期网民对哪些事件的关注热度，我们需要做的是把这些关键字融入到我们的帖子标题当中去，但是内容不一定是跟排行榜内容一样的，但是能反映关键字的内容，那么对于搜索引擎来说，关键字有了，内容的不同让它相信我们的是原创，而不是盲目的网上跟风复制，有些关键字它是永远都不会过期的，我们经常的把排行的关键字融入到了我们各种帖子的标题里面，久而久之，我们论坛它就是一部关键词字典，我今天把百度蜘蛛比作是一个食客的话，那么我的站就是各种小吃、名菜的天堂，对于食客来说那是莫大的诱惑。

首先从报文结构上来看，报文分为3部分：报文头、报文体、MAC地址，使报文传输的安全性达到了国际金融行业的标准；其次，从加密方式来看，本次系统最突出的两个加密分别是对管理员密码进行加密、对卡密码进行加密，特别是对卡密码的加密，运用的是软加密服务接口技术，运用工作密钥，主密钥，原始密码通过算法得到密钥密文通过两次不同的DES加密才得出的密钥，可想而知，想要同时得到我的工作密钥，主密钥，原始密码密文本来就比较困难了，要是再解两次DES，可以说是完全不可能实现的！
