Advances in Social Sciences (ASS) , 2015, DOI: 10.12677/ASS.2015.42016
Abstract:
本研究探讨了网络用户对剩男剩女的社会态度。采用微博文本情感倾向分析的方法对1000条新浪原创微博进行态度研究。采用微博文本情感倾向分析的方法对1000条新浪原创微博进行态度研究,其结果显示微博用户对剩男剩女群体持负向态度。另对标签为剩男剩女的60名新浪微博用户近期发表的900条原创微博进行情感倾向性分析,发现剩男剩女群体的微博呈中性态度,且剩男和剩女的微博关注话题存在明显性别差异。本研究结果对于社会正确理性看待逐渐增多的剩男剩女具有一定的启示意义,对剩男剩女在择偶问题上树立正确择偶观具有引导作用。
This study investigated the Internet users’ social attitude towards leftover males and females. Re-lated to the topic of leftover males and females, 1000 original micro-blog messages selected from Sina Weibo were used to identify the emotional tendencies of these messages. The results showed that the micro-blog users held negative attitude towards leftover males and females. In addition, the emotional tendencies of the 900 original micro-blog messages that were recently published from 60 Sina Weibo users who were marked by leftover males or females were analyzed as well. The results showed that the emotional tendencies of these messages were neutral. Besides, there were dramatically differences on the topics focused by leftover males and females. The research not only induces a rational social attitude towards leftover males and females, but also plays a guiding role for them in setting up the correct conception on choosing spouse.

Abstract: 髌骨损伤容易引起膝关节功能性障碍,常出现于年轻及运动较多、量较大的人群,而髌骨脱位则是其最常见的临床表现。目前来讲,在髌骨损伤诊断中,CT扫描图像有着重要的临床价值,通过CT扫描图像测量获得的与髌骨、股骨相关的数据,如Q角、髌骨倾斜角、外侧髌骨移位值、TT-TG等数据为主治医师的诊断提供了重要的数据支撑,在一定程度上提高了主治医师对髌骨损伤类型诊断的正确率。
Patella injury which often occurs in the young people with more exercise can cause functional disorder of the knee joint, and patellar dislocation is one of the most common clinical manifestat- tions. At present, CT image has the important value in the patella injury clinical diagnosis, and the date related to patella and femur obtained by CT such as Q angle, patella tilt angle, lateral patella displacement value and TT-TG can provide the important data support for the physician’s diagnosis, and also improve the diagnostic accuracy of the patella injury on some level.

Abstract: 本文选择汉江流域18个国家气象站的长序列观测资料,采用数理统计、Mann-Kendall检验和Spearman秩次检验法,分别从降雨和气温两个方面,对跨流域调水环境下汉江流域降雨和气温变化特性进行了分析。研究结果表明:1) 丹江口以下流域的多年面均雨量较丹江口以上流域多了158.7 mm;汉江流域温度在1990年以后均出现了明显的升高。2) 经降雨和气温趋势分析可知,汉江流域的降雨无明显的变化趋势,而气温则有显著的升高趋势。3) 在整个汉江流域的降雨无明显变化,而气温显著升高的情况下,考虑到未来跨流域调水以及工农业用水规模的增加,汉江流域水资源量的供需矛盾将不容乐观。
In order to evaluate the characteristics and change trend of the surface precipitation and temperature in the middle and lower reaches of the Hanjiang River before the working of the middle route of the South-to- North Water Diversion Project, eighteen meteorological stations were selected. Furthermore, mathematical statistics, Mann-Kendall test and Spearman test were used, and two aspects of temperature and runoff were analyzed based on the meteorological data of the selected stations. The results are as follows. 1) The surface precipitation of the upper drainage area of Hanjiang River basin is 158 mm more than that of the lower drainage area; the temperature of the whole basin has been raised since 1990. 2) After trend analysis, it unfolds that the change trends of the rain-time series in this region are not noticeable, but the temperature shows a significant rise. 3) The imbalance between water supply and demand in the lower Hanjiang River basin will be very conspicuous, if there are not any engineering and non-engineering actions to take.

Abstract:
目前我国建筑工程项目存在“信息传递效率低、信息协同和共享性差、信息利用价值低”的现状,通过对建设项目各阶段各参与方之间的信息进行分析,建立基于BIM的建筑供应链信息模型并对其运行保障机制进行分析,探讨通过建筑供应链管理模式对实现建设工程项目高效管理、提高建设项目的技术水平和生产效率起到促进作用。
At present, low efficiency of information transfer, poor information collaboration and sharing, and low utilization value of information are the current situations of construction projects in our country. Based on the analysis of information among all the construction project parties in different stages, the paper establishes information model of construction supply chain based on BIM, analyzes its operation guarantee mechanism, and discusses that the management model of construction supply chain plays a promoting role in achieving efficient management, improving the level of construction technology and promoting the production efficiency of construction engineering projects.

Abstract:

本文首次对半夏的花粉活性和柱头可授性进行了研究,以期为半夏的有性繁殖和育种研究提供科学依据。在3种测定半夏花粉活力的方法中,TTC染色法的染色效果不理想;MTT染色法最优,使花粉出现紫色、淡红色、无色三种颜色反应,利于观察,其染色率为86.59%;次甲基蓝染色法的染色效果次之,但染色率略高于TTC染色法,为89.62%;半夏雌花在一天中的开放时间略早于雄花,其花粉活力与柱头可授性相遇时间为48~72 h;散粉集中于开花第3、4天,此时花粉数较多,花粉活力维持在85.15%~94.11%;而于开花前一天、开花当天和开花第2天的柱头活性较强;人工控制授粉可提高半夏的结实率和种子数量。
This paper studied on the pollen viability and stigma receptivity of Pinellia ternate for the first time, as to provide a scientific basis for sexual reproduction and breeding of new varieties. In the three determination methods of P. ternata pollen activity, the staining effect of TTC was not ideal. The staining effect of MTT was best, which was beneficial to identify pollen viability, because it made pollen come out three kinds of color reaction of purple, faint red and colorless. Its dyeing rate was 86.59%. The staining effect of methylene blue was better, but the dyeing rate was higher than MTT, which was 89.62%. The opening time of P. ternata’s female flower was slightly earlier than male flower in a day. There were 48 - 72 h to make an appointment between pollen and stigma receptivity. Pollen scattering was concentrated on the third and fourth days of flower opening. During this period of time, the number of pollen was larger and the pollen activity was kept between 85.15% - 94.11%. The stigma receptivity was high during the former day, the very day and the second day of blooming. Artificially control pollination could improve the seeds setting percentage and seed number of P. ternata.
