联通公司移动业务经营指标体系研究

电信行业在信息化的时代中发挥着重要的作用,随着电信行业重组以及4G移动牌照的发放,电信行业的竞争也更加激烈。联通公司作为电信行业中具有优势竞争力的企业之一,如何在新的时期确保持续、稳定的发展,增强企业竞争力,提高企业经营业绩,是要重点研究的问题。移动业务是联通公司的核心业务,移动业务经营指标体系是企业对自身业务发展进行评价的主要依据,研究联通公司移动业务经营指标体系,对于企业今后的发展具有重大意义。本文笔者将对联通公司移动业务经营指标体系构建的原则、体系内容进行详细论述,并说明如何应用移动业务经营指标体系。     

王棨《麟角集》版本考述

王棨诗被其八世孙南宋王苹辑录,其赋则由其十九世孙王观辑录并命名为<麟角集>,后经王尚访补得以完善.入清后<麟角集>被重新刊刻或抄写,共有13个不同版本,经过清代著名学者鲍廷博校并收入<知不足斋丛书>的<麟角集>为较好的版本.     

Impact of divalent salts and bovine gelatin on gel properties of phosphorylated gelatin from the skin of unicorn leatherjacket

The impact of zinc chloride (ZnCl₂) and calcium chloride (CaCl₂) as well as bovine gelatin (BG) on the gel strength of phosphorylated fish gelatin (PFG) from the skin of unicorn leatherjacket was investigated. The gel strength of PFG increased with increasing concentrations of ZnCl₂ and CaCl₂ (2.5–40 μmol L⁻¹). A higher gel strength was observed with CaCl₂, compared with ZnCl₂. The gel strength of PFG with 20 μmol L⁻¹ CaCl₂ increased by 15.7%, compared to the control gel. Nevertheless, at higher concentration (40 μmol L⁻¹) of both salts, gel strength of PFG decreased. Hardness of gels decreased with increasing PFG content (P < 0.05). Nevertheless, no differences in hardness were found amongst gels with BG/PFG ratios of 4:0 and 3:1 (P ≥ 0.05). Thus, PFG could be used in combination with CaCl₂ to substitute for BG at a level of 25%.     

麒麟文化与古建门饰

本文追溯了麒麟外形的演变过程和不同时期的形态特征，分析了麒麟作为“仁兽”、“贤王”、“驱邪送子”等方面的文化象征意义。重点探讨了麒麟纹样在传统建筑门神画、影壁、门枕石等门饰中的运用。     

中国移动通信市场:寡头垄断,价格战不可取

双寡头垄断市场具有折弯价格需求曲线,该折弯价格需求曲线的折弯程度与市场饱和度成正相关,曲线的折弯点表示双寡头市场份额稳定时,也即是双寡头停止价格战的时候。中国移动公司和中国联通公司在2002年末之前的价格竞争符合经济规律,这之后的竞争则是盲目的．国家及运营商应该加以重视。

Characteristics of gelatin from the skin of unicorn leatherjacket (Aluterus monoceros) as influenced by acid pretreatment and extraction time

Gelatins from the skin of unicorn leatherjacket (Aluterus monoceros) pretreated with different acids (0.2 M acetic acid or 0.2 M phosphoric acid) and extracted with distilled water at 45 °C for various times (4 and 8 h) were characterized. Yields of 5.23–9.18 or 6.12–11.54% (wet weight basis) were obtained for gelatins extracted from the skin pretreated with 0.2 M acetic acid or 0.2 M phosphoric acid, respectively. Extracted gelatins contained α₁ and α₂ chains as the predominant components and some degradation peptides. The absorption bands of gelatins in FTIR spectra were mainly situated in the amide band region (amide I, amide II and amide ???) and showed the significant loss of molecular order of triple helix. Gelatin samples had a relative solubility greater than 90% in the wide pH ranges (1–10). The gel strength of gelatin from skin pretreated with phosphoric acid (GPA) was higher than that of gelatin from skin pretreated with acetic acid (GAA). Both GPA and GAA had the lower gel strength than that of commercial bovine gelatin (P < 0.05). Net charge of GAA and GPA became zero at pHs of 6.64–7.15 and 6.78–7.26, respectively, as determined by zeta potential titration. Emulsifying and foaming properties of GAA and GPA increased with increasing concentrations (1–3%, w/v). Those properties were governed by pretreatments and extraction time. Thus gelatin can be successfully extracted from unicorn leatherjacket skin using the appropriate acid pretreatment and extraction time.     

中国联通WLAN业务发展策略初探

自国内电信行业重组以来,特别是2009年1月7日,工业和信息化部批准了中国电信、中国移动和中国联通的3G业务经营许可,国内三大基础电信运营商正式进入了全业务运营时代。移动数据业务,特别是移动互联网业务,是3G业务的主要内容之一。在3G时代,WLAN技术凭借其低成本、高速率的特点,将在3G网络建设和业务应用中发挥独特的作用。中国联通在WLAN的发展上起步较晚,采用什么样的业务发展策略来充分发挥自身的综合实力优势以赢得市场获得胜利是其急需解决的问题。本文以中国联通为例分析了其在3G时代这个大背景下的WLAN业务发展内外部环境并提出了相应的业务发展策略。
