Research on the Developing Model of Comprehensive Holiday Site on KaiKou Golf Course

高尔夫是一项带着精英色彩的体育运动,它健康、时尚并兼有运动、休闲、娱乐、社交等多种功能，其英文名GOLF恰巧表明了这一运动的本质特征……凯歌曾经是辉煌和骄傲的，让人充满着憧憬和梦想。但凯歌十年来由盛而衰的惨淡经营却让人扼腕叹息、发人深思。这其中有其自身的原因，亦有行业发展和市场竞争的因素。凯歌自开发建设到运营至今跨度达十五年之久，这“一路风雨，一路凯歌”的历史从某种意义上是中国高尔夫行业的一个缩影，有着相当的代表性。因此，对凯歌高尔夫球场过去和现在的研究与思考，对于凯歌高尔夫球场将来战略发展的研究与探讨，对于仅有二十年发展历史还处在尝试探索阶段的中国高尔夫行业有着相当的现实意义。本文借鉴企业战...Golf is a sport with the color of essence. It’s healthy, fashionable, beneficial and has recreation, socialization, travel etc functions. Its English name happens to show the genius character….. KaiKou was splendid and pride, full of longing and dreams. But after 10 years’ gloomy operation, we have to think deeply on the experience from prosperousness to wane. The reasons are not only internal fac...学位：工商管理硕士院系专业：管理学院工商管理教育中心_工商管理硕士(MBA)学号：20001506

HIRFL大型真空系统；The vacuum system of HIRFL

HIRFL是兰州重离子加速器装置的英文首字母缩写,其真空系统是一个大型综合性系统。HIRFL由离子源、扇聚焦回旋加速器SFC、分离扇回旋加速器SSC和多用途的重离子冷却储存环(HIRFL-CSR)组成。多条束流运输线将这些加速器连接在一起,同时将各种重离子束流送往10多个实验终端。根据加速离子和束流寿命的需要,对各加速器真空度的要求是不同的:SFC已有50多年的历史,经过3次升级改造,真空度从10-4 Pa提高到10-6 Pa;建于上世纪八十年代的SSC真空度也为10-6 Pa;而两个重离子冷却储存环(CSRm和CSRe)的真空度达到10-10Pa以保证重离子有足够长的储存寿命。多条连接束运线根据不同实验终端的要求,其真空系统的设计方案也不同,文中列举了微束实验终端采取的防振措施;为充气反冲谱仪设计的清洁、大流量真空差分系统及为重离子治癌等终端设计的超薄壁扫描磁铁真空管道等

会宁胡麻油产地环境及产品特征 Production environment and product characteristic of Huining flaxseed oil

为提高会宁胡麻油品牌知名度和影响力，探究了地理标志产品会宁胡麻油的产地环境、种植方式及生产管理过程和品质特性。以会宁县17个乡镇的土壤和胡麻油为试验材料，采用国家相关标准对产地环境及胡麻油品质进行分析并采用气相色谱-质谱法对胡麻油风味物质进行分析。结果表明：会宁胡麻油的产地环境和产品安全指标均达到绿色食品标准；会宁胡麻油中α-亚麻酸平均含量为54.24%，不同产地间存在一定差异；会宁胡麻油含有65种风味物质，香味浓郁，其中己醛、正己醇、2-甲基吡嗪、γ-己内酯和3-甲基巴豆腈对会宁胡麻油独特的香味有重要影响。综上，会宁胡麻生长环境好，会宁胡麻油香味浓郁、营养价值高。In order to improve the brand awareness and influence of Huining flaxseed oil, the production environment, cultivation method and production management process, and quality characteristics of Huining flaxseed oil, a geographical indication product, were explored.The soil and flaxseed oil from 17 townships in Huining county were used as test materials, and the production environment and product quality were determined by the relevant national standards, and the flavor compounds of flaxseed oil were determined by GC-MS method.The results showed that the production environment and product safety indicators of Huining flaxseed oil could meet the standards of green food; the average content of α-linolenic acid in Huining flaxseed oil was 54.24%, moreover, there was difference among different townships.Furthermore, the flaxseed oil of Huining contained 65 flavor compounds and had aromatic flavor, of which hexanal, hexyl alcohol, 2-methylpyrazine, γ-caprolactone, and 3-methyl crocetonitrile had important effect on the unique scent of Huining flaxseed oil.In summary, the flaxseed of Huining grows in a good environment and the oil has a rich aroma and high nutritional value

JUNO Sensitivity on Proton Decay p→νˉK+p\to \bar\nu K^+ Searches

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this paper, the potential on searching for proton decay in $p\to \bar\nu K^+$ mode with JUNO is investigated.The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits to suppress the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar\nu K^+$ is 36.9% with a background level of 0.2 events after 10 years of data taking. The estimated sensitivity based on 200 kton-years exposure is $9.6 \times 10^{33}$ years, competitive with the current best limits on the proton lifetime in this channel

JUNO sensitivity on proton decay p → ν K + searches*

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this study, the potential of searching for proton decay in the $p\to \bar{\nu} K^+$ mode with JUNO is investigated. The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits suppression of the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar{\nu} K^+$ is 36.9% ± 4.9% with a background level of $0.2\pm 0.05({\rm syst})\pm$$0.2({\rm stat})$ events after 10 years of data collection. The estimated sensitivity based on 200 kton-years of exposure is $9.6 \times 10^{33}$ years, which is competitive with the current best limits on the proton lifetime in this channel and complements the use of different detection technologies
