很显然是需要的，刚刚才看了一篇英文文献，不信你看1134和mg之间是由一个字符间距的，而且mg和kg之间也是由一个字符间距的，所以在英文表达中应该是5 m而不是5m。希望对你有用
写论文？
普通的单位和数字之间都需要空格的，但是也存在特殊的，比如色谱柱中XBridge Peptide BEH C18 OBD Prep Column, 300Å, 5 µm, 19 mm X 100 mm, 1/pkg 注意加粗的是不需要空格的，还有一些符号容易混淆但是不需要空格的，比如20%、37℃ 等，希望对你有用
Repeat Bidding on Internet-Based Multiple-Item "Name-Your-Own-Price" A Authors: Gupta, Abhimanyu1 Abbas, Au E2 du Abstract:Name-Your-Own-Price (NYOP) auctions have gained recent popularity on the I In many NYOP settings, the auction firm displays multiple bidding items for the bidders (such as multiple options of airline tickets) and restricts them to place a single Recent studies have, however, shown that the Internet environment enables many customers to engage in repeat Our purpose in this paper is: 1) to analyze the consumer value gained by repeat bidding on multiple-item NYOP auctions under different-bidding strategies; 2) to derive an upper bound on the value gained by repeat bidding when multiple items are present; and 3) to analyze the multiple-item NYOP auction from a consumer-firm We use Monte Carlo simulation to discuss the effects of various auction parameters on the firm's expected profit, and show that the presence of multiple bidding items provides a win-win situation for both the auction firm and the In particular, we show that multiple items increase the expected value for the consumers and also help firms mitigate potential losses due to repeat Slow Dutch auctions; Carare, O; Rothkopf, M Management Sci; 2005 V 51 Issue 3, p365-373, Document Type: Article Citation; (AN MSEACFECARARESDA) [Citation Record] PDF Full Text (130KB) Add to folder Remove from folderTimes Cited in this Database: (7) Order S Order Statistics; David, HA; 1981 : Wiley (2nd edition) Document Type: Book Citation; (AN OSDAVIDWILEYAIHA) [Citation Record] Add to folder Remove from folderTimes Cited in this Database: (47) Reverse pricing: The Impact of Sophisticated Consumers, Seller Commitment, and C Reverse pricing: The Impact of Sophisticated Consumers, Seller Commitment, and Competition; Fay, S Working Paper; 2007 : University of F Document Type: Book Citation; (AN WPFAYUNIVERSITYOFFLORIDABJJG) [Citation Record] Add to folder Remove from folderTimes Cited in this Database: (1) Partial-repeat-bidding in the name-your-own-price Partial-repeat-bidding in the name-your-own-price channel; Fay, Scott Marketing S; 2004 V 23 Issue 3, p407-418, Document Type: Article Citation; (AN MSBCDJGFAYPNC) [Citation Record] PDF Full Text (169KB) Add to folder Remove from folderTimes Cited in this Database: (7) The social cost of cheap The social cost of cheap pseudonyms; Friedman, E; Resnick, P J E Management Strategy; 2001 V 10 Issue 1, p173-199, Document Type: Article Citation; (AN JEMSAJAGCFRIEDMANSCCP) [Citation Record] PDF Full Text (654KB) Add to folder Remove from folderTimes Cited in this Database: (28) Measuring frictional cost of online transaction: The case of a NYOP- Measuring frictional cost of online transaction: The case of a NYOP-retailer; Hann, I H; Terwiesch, C Management S; 2003 V 49 Issue 11, p1563-1579, Document Type: Article Citation; (AN MSDIAEFCHANNMFCOTC) [Citation Record] PDF Full Text (233KB) Add to folder Remove from folderTimes Cited in this Database: (19) An exploration of the adoption of e-auctions in supply An exploration of the adoption of e-auctions in supply management; Hartley, JL; Lane, MD; Hong, Y IEEE Transactions on Engineering Management; 2004 V 51 Issue 2, p153-161, Document Type: Article Citation; (AN ITEMEAAECHARTLEYEAESM) [Citation Record] Add to folder Remove from folderTimes Cited in this Database: (12) Value of information Value of information lotteries; Howard, R A IEEE T S S C; 1967 V SSC-3 Issue 1, p24-60, Document Type: Article Citation; (AN ITSSCSSCBDHOWARDVIL) [Citation Record] Add to folder Remove from folderTimes Cited in this Database: (1) Auctions on the internet: What's being auctioned, and how?

航班座位价值的易逝性和供给能力的短期非调节性，使得价格成为航空公司以及其它服务企业调剂需求，提高收益的最有效的工具。以此为主要探究对象的收入管理定价探究，长期以来集中于探索垄断假设下的定价模型，而忽略了现实生活中，一条航线上往往存在几个航班相互竞争的事实。并且，随着电子客票的发展和信息搜索技术的进步，消费者获得各航空公司价格信息，进而进行比较、选择的成本大大降低。在这种条件下，航空公司继续采用基于垄断市场假设的收入管理动态定价模型所给出的价格策略，很难达到预期的效果。出于理论上的缺陷和现实中的需要，本文构建了一个考虑竞争因素的动态定价模型。 首先，改进了单航班动态定价模型，对单航班动态定价新问题进行重新建模。和传统的动态定价模型以价格集合作为模型变量不同，本文所建立的模型直接以不同价格切换的时间点作为决策变量，使期望收益和价格决策的函数关系更加清楚。使在多航班情况下刻画对手价格变化对自身收益的影响变得可能，为建立竞争环境下的动态定价模型打下基础。 其次，在单航班模型的基础之上，从市场上每笔交易的细度，递推地刻画了航班售票的全过程，构建了考虑两个竞争航班、各自提供两种价格等级时的一【来源】竞争环境下的民航客运收入管理动态定价模型
