把分子连接性指数法应用到10种氨基酸、11种硫醚、6种硫醇和20种醛、酮的2,4-二硝基苯腙薄层色谱保留值的相关性研究中。
6)  reservation value
保留值
1.
On the aboue assumption, this paper studies reservation value setting and draws conclusions that reservation value has no pertinence with the expected number of bidders while the expected number of bidders affect expected revenue of the auctioneer.
在Friedman对投标人数所作的服从Poisson分布假定的基础上,研究了招标活动中招标商对最优保留值的设置问题,得出了最优保留值的设置与参与投标的期望人数无关以及招标商的期望收益受参与投标的期望人数影响的结论,同时给出了最优保留值的设置公式,从而给招标机制的设计提出了一种更接近实际情况的方法。
2.
The deficiency of setting reservation value in practical bidding and present articles related to auctions is aimed in this paper, the setting method of optimal reservation value is studied when reservation value is related to the numbers of bidder, the theorem that the bid taker s profit reaches maximum at some assumption is presented, and the strict theoretical inference is given.
本文针对实际招标投标和现有有关拍卖的文献中保留值设置方法的不足,研究了保留值的大小与投标商人数相关时的最优保留值的设置方法,提出了在一定的假设条件下招标商的收益达到最大的定理,并给出了严格的理论推
补充资料:相对保留值
分子式:
CAS号:

性质:在相同操作条件下,待测组分与参比物的调整保留值(调整保留时间或调整保留体积)之比称为相对保留值。对于给定的色谱体系,在一定温度下,相对保留值是一个常数,它与色谱柱的长度、内径及流动相流速无关。
