Research on the application of Balanced Score Card in A Gas Co

本世纪初到2013年下半年，是我国天然气行业发展的黄金10年，短短10余年，从资源丰富的西部地区、经济发达的东南沿海地区，再到内陆地区，天然气行业得到了迅猛发展，从1998年到2010年，在国内能源消费总和中,天然气所占比重已从2.1%上增长到6%，预计2020年，会继续攀升至10%。与此同时，燃气行业竞争愈加激烈，国资、民营、外资，各路资本“开疆拓土”，不断渗透到国内大小城市。在这种局面之下，外部环境复杂多变、市场竞争日益激烈、技术创新不断深化等等因素，企业如何保持自身优势，是企业未来将要思考的重要问题。 本文利用基于平衡计分卡的绩效评价理论，结合案例公司的具体实施方案，归纳总结出一套在行...This century at the beginning to the end of 2013, is a gold 10 years of China's natural gas industry development, just more than 10 years, from the resource rich western region, economically developed southeast coastal area, to the inland area, natural gas industry has been rapid development, in 2010, the proportion of natural gas in the total energy demand has from 2.1 percent in 1998 rose to 6%,...学位：工商管理硕士院系专业：管理学院_工商管理硕士(工商管理硕士)学号：1792013115091

广东中山水栖寡毛类区系调查

中山市位于珠江三角洲中南部,区内分布江河、溪流、水库、池塘等多种水体,迄今未见对该地区水栖寡毛类区系的研究报道。通过2005年6月和12月两次调查,记述中山市水栖寡毛类31种,隶属4科16属,包括1个国内新纪录种即扇形管盘虫(Aulophorus flabelliger)以及19个广东省新纪录种。区系分析表明,中山有较多的喜温种类

FACTORS AFFECTING THE FERTILIZATION SUCCESS IN LABORATORY HYBRIDIZATION BETWEEN HALIOTIS DISCUS HANNAI AND HALIOTIS GIGANTEA

In this study, effects of sperm concentration and gamete age on fertilization success of Haliotis discus hannai (D) X H. gigantea (G) were investigated. Results showed that the fertilization rates of heterologous crosses H. discus hannai female x H. gigantea male (DG) and H. gigantec female X H. discus hannai male (GD) were consistently lower than those of homospecific groups H. discus hannai female x H. discus hannai male (DD) and H. gigame female X H. gigantea male (GG). In sperm concentration experiments, the sperm concentrations that yielded maximum fertilization rates with the least abnormality in subsequent development were 4.66 X 10(7) sperm/mL for the DG cross and 2.6 x 10(7) sperm/mL for the reciprocal cross GD. In gamete age experiments, the optimal fertilization rates were achieved in heterologous crosses when freshly spawned ova were fertilized with sperm that were released within 0.5 h. Furthermore, in heterospecific crosses, when ova were fertilized 10 min after being spawned, fertilization rates declined significantly with increasing ova age. It is suggested to use fresh gametes and higher sperm concentrations for hybridization between H. discus hannai and H. gigantea

对冲湍流预混火焰熄灭特性的实验研究

采用对冲火焰实验系统对甲烷/空气湍流火焰发生熄灭的极限条件进行考察,分析了平均流场拉伸和湍流拉伸对火焰熄灭的影响。实验结果表明,随着甲烷/空气火焰的当量比接近1,其熄灭时的平均射流速度UE以及平均极限拉伸率随之增大,对冲喷口间距减小时UE也随之减小。当量比一定的条件下,当喷口间距接近两倍喷口直径时,不同间距对应的UE值逐渐接近。当量比趋近1时

GENETIC CORRELATIONS TO MORPHOLOGICAL TRAITS OF SMALL ABALONE HALIOTIS DIVERSICOLOR

A total of 241 samples of small abalone (Nation's diversicolor) from 8 full-sib families of market size were used in this experiment. Shell length (X-1), shell width (X-2), shell height (X-3), apex height (X-4), body weight (Y-1), muscle weight (Y-2), and shell weight (Y-3) were measured, and the correlation coefficient matrix was calculated. The shell shape traits were used as independent variables, then body weight and muscle weight were used as dependent variable for path analysis. Path coefficients, determination coefficients, and correlation index were calculated. The results showed that correlation coefficients between each shell shape trait and body weight, muscle weight, and shell weight were all significant (P < 0.01). For the 4 shell morphological traits, body weight (Y-1) had the highest correlation coefficient with shell length (X-1), and muscle weight (Y-2) had the highest correlation coefficient with shell width (X-2). The results of high correlation index would be useful for selecting important growth-related traits in genetic breeding program of small abalone

渤海典型生态灾害的发展变化特征及演变趋势
