《红楼梦》儿化词运用规律探讨

《红楼梦》①中的京腔京调以亲昵、喜爱、生动、轻灵的语句著称于世,对现代汉语普通话有很大的影响。北京话的特色是流畅圆美又简洁,特别是儿化词的使用贯穿始终,在语气上更有一种音韵美,读来使人对小说再现的北京生活气息油然而生亲切之感。儿化词在该书中的运用比较普遍,百二     

电价管制模式的国际比较及借鉴

随着电力产业的发展,人们对电价管制模式的研究也越来越多。传统的电价管制模式有以英国为代表的最高限价管制和以美国为代表的投资回报率管制。本文主要探讨了英国和美国的电价管制模式,并分析了它们对中国电价管制的可借鉴之处。     

Designing a trust evaluation model for open‐knowledge communities

The openness of open‐knowledge communities (OKCs) leads to concerns about the knowledge quality and reliability of such communities. This confidence crisis has become a major factor limiting the healthy development of OKCs. Earlier studies on trust evaluation for Wikipedia considered disadvantages such as inadequate influencing factors and separated the treatment of trustworthiness for users and resources. A new trust evaluation model for OKCs—the two‐way interactive feedback model—is developed in this study. The model has two core components: resource trustworthiness (RT) and user trustworthiness (UT). The model is based on more interaction data, considers the interrelation between RT and UT, and better represents the features of interpersonal trust in reality. Experimental simulation and trial operation for the Learning Cell System, a novel open‐knowledge community developed for ubiquitous learning, show that the model accurately evaluates RT and UT in this example OKC environment.     

大学生纸本文献阅读研究——以山东农业大学为例

以山东农业大学为样本,对大学生纸本文献阅读现状进行问卷调查。统计分析发现,目前纸本文献阅读依然是大学生首选的阅读对象;认为影响纸本文献阅读的因素主要有三个,即文献资源、场所及服务。为此指出高校阅读推广应从这三个方面着手：根据阅读倾向的变化调整藏书结构,减少学术期刊的订购比例;改善环境条件;开展互动式服务。     

蹦床运动发展中的问题及其对策探究

蹦床运动历史悠久,素有“空中芭蕾”的美称。与国外蹦床运动广泛开展相比,中国的蹦床运动虽起步较晚,但发展非常迅速,且近年来成绩骄人。然而蹦床运动在我国的根基却十分薄弱,所以体育工作者应认真研究,制定发展策略,建立长效机制,力求实现中国蹦床的可持续发展。

The construction of an interfacial valve-based microfluidic chip for thermotaxis evaluation of human sperm

Thermotaxis has been demonstrated to be an important criterion for sperm evaluation, yet clinical assessment of thermotaxis capacity is currently lacking. In this article, the on-chip thermotaxis evaluation of human sperm is presented for the first time using an interfacial valve-facilitated microfluidic device. The temperature gradient was established and accurately controlled by an external temperature gradient control system. The temperature gradient responsive sperm population was enriched into one of the branch channels with higher temperature setting and the non-responsive ones were evenly distributed into the two branch channels. We employed air-liquid interfacial valves to ensure stable isolation of the two branches, facilitating convenient manipulation of the entrapped sperm. With this device, thermotactic responses were observed in 5.7%-10.6% of the motile sperm moving through four temperature ranges (34.0-35.3 °C, 35.0-36.3 °C, 36.0-37.3 °C, and 37.0-38.3 °C, respectively). In conclusion, we have developed a new method for high throughput clinical evaluation of sperm thermotaxis and this method may allow other researchers to derive better IVF procedure.
