Objective: The motor thalamus plays an important role during exercise. It aims to observe the changes of mGluR4 and mGluR5 in ventrolateral thalamus of rats induced by repeated exhaustive exercise, and to discuss the relationship of mGluR4, mGluR5 and oxidative damage occured during exhaustive exercise. Methods: There were 48 male wistar rats, which were randomly divided into four groups including CG, 0EG, 24EG and 48 EG, each group having 12 rats. Meanwhile, immunohistochemistry (IMM) technique was used to investigate the expression of positive cell and integrated optical density (IOD) of metabotropic glutamate receptor 4 (mGluR4) and metabotropic glutamate receptor 5 (mGluR5), and the impact of exhaustive exercise played on oxidative stress indexes such as malondialdehyde (MDA), glutathione peroxidase (GSH-PX) and superoxide dismutase (SOD) in ventrolateral thalamus of rats were also investigated in different groups. Results: Compared with CG, the expression of mGluR4 and mGluR5 protein of ventrolateral thalamus in 0EG and 24EG both significantly increased, and the value of mGluR4 in 48EG were still higher than control group, however the the value of mGluR5 in 48EG reduced to the rest level of control group. Meanwhile, the SOD activities of 0EG and 24EG group were significantly higher than the control group, and it was the same with GSH content in ventrolateral thalamus of rats. Meanwhile, MDA has been investigated that it increased significantly in 0EG and 24EG compared with control group, and the MDA level of 48EG was still significant higher than CG. Moreover, the indexes of muscle injury such as LD, CK and BUN all increased significantly post-exercise immediately and post-exercise 24 hours .Conclusion: Exercise fatigue could result in up-regulation of mGluR4 and mGluR5 and increace activity of SOD , GSH-PX and MDA in ventrolateral thalamus of rats, and it also induce the muscle injury by increase the level of LD, CK and BUN in serum, which suggested that ventrolateral thalamus was an important brain rigion to modulate the motor function, and mGluR4 and mGluR5 maybe two important receptors prevent from the increase of free radicals and muscle injury induced by exercise fatigue.
目的:运动丘脑在运动过程中发挥重要作用。观察反复穷尽运动诱导大鼠腹外侧丘脑mGluR4、mGluR5的变化,探讨mGluR4、mGluR5与穷尽运动中氧化损伤的关系。方法:雄性wistar大鼠48只,随机分为CG、0EG、24EG、48eg 4组,每组12只。同时,采用免疫组织化学(IMM)技术检测代谢性谷氨酸受体4 (mGluR4)和代谢性谷氨酸受体5 (mGluR5)的阳性细胞和综合光密度(IOD)的表达,并研究穷竭运动对不同组大鼠腹外侧丘脑丙二醛(MDA)、谷胱甘肽过氧化物酶(GSH-PX)、超氧化物歧化酶(SOD)等氧化应激指标的影响。结果:与CG相比,0EG和24EG大鼠腹侧丘脑mGluR4和mGluR5蛋白表达均显著升高,48EG大鼠mGluR4值仍高于对照组,48EG大鼠mGluR5值降至对照组水平。同时,0EG和24EG组SOD活性显著高于对照组,与大鼠腹外侧丘脑GSH含量相同。同时,我们研究了MDA在0EG和24EG组较对照组显著升高,48EG组的MDA水平仍显著高于CG组。运动后即刻及运动后24 h,肌肉损伤指标LD、CK、BUN均显著升高。运动疲劳可导致大鼠腹外侧丘脑mGluR4、mGluR5表达上调,SOD、GSH-PX、MDA活性升高,并通过提高血清LD、CK、BUN水平诱导肌肉损伤,提示腹外侧丘脑是调节运动功能的重要脑区,mGluR4和mGluR5可能是两个重要受体,可预防运动疲劳引起的自由基增加和肌肉损伤。

Zheng Chao Lv Et al.
In order to overcome the deficiencies of miss-seeding and random seeding in the current ground wheel driven seeding,a set of intelligent control simulation system for wheat precision seeding was studied and built.The system adopts self-designed seeding apparatus and intelligent control method to complete broad width and precision seeding of wheat. The system uses keys to set parameters such as seeding rate, thousand-grain weight and seeding space, etc.According to the measured value of the operating speed of the planter by the encoder, the speed of the DC motor is dynamically adjusted by controlling the pulse width modulation (PWM) of the chip, so as to achieve the purpose of changing the operating speed of the seeder and keeping the seeding rate and seed spacing unchanged. The DC motor is poweredby tractor’s own battery to drive seeding, and all information is displayed on the LCD.The simulation test of the rotation speed measurement of the seeding shaft shows that there is only slighterror caused by vibration between the corresponding theoretical and actual rotation speeds of the seeding shaft for different operating speeds when the intelligent control system of wide planting of wheat is used for seeding, which can meet the requirements of precision seeding.
为了克服目前地面轮驱动播种存在的漏播和随机播种的不足,研究建立了一套小麦精密播种智能控制仿真系统。该系统采用自行设计的播种机和智能控制方式,完成小麦的宽播、精播。该系统通过按键设置播种机的播种率、千粒重、播种机间距等参数,根据编码器测得播种机运行速度的值,通过控制芯片的脉宽调制(PWM)动态调节直流电机的转速,从而达到改变播种机的运行速度,保持播种机的播种率和播种机间距不变的目的。直流电机由拖拉机自带电池驱动播种,所有信息均显示在液晶显示屏上。对播种机轴转速测量的仿真试验表明,采用小麦宽播智能控制系统播种时,在不同运行速度下,播种机轴对应的理论转速与实际转速之间只有轻微的振动引起的震动,能够满足精准播种的要求。

In the process of tourism development, there are some problems that can not be ignored, such as the destruction of natural environment by scenic spot development, unfair competition in the industry, and infringement of employees' rights and interests by enterprises, which directly restrict the development of tourism industry. The issue of tourism corporate social responsibility has been in the sight of global scholars and practitioners. First of all, this paper will study and analyze the relevant theories made so far by scholars and practitioners at home and abroad, to understand the research status of social responsibility of tourism listed companies at home and abroad, as well as the status quo of corporate social responsibility. Secondly, this paper selects 23 domestic tourism listed companies to collect the panel data of their social responsibility reports from 2014 to 2018, and makes an empirical analysis on the sorted panel data through the statistical software Eviews, so as to explore the impact of social responsibility of tourism listed companies on their business performance, And draw the conclusion that tourism listed companies' business responsibility has a positive impact on their business performance, but there is a certain lag in this impact. Based on the research, this paper puts forward some feasible suggestions for tourism enterprises to take the initiative to undertake social responsibility, hoping to provide some help to scholars in related fields and practitioners in enterprises.

Song Mei, Zhen-yuan Zhu, Ping Leng
Academic burnout of basic education is widespread in varying degrees in the global scope, and such situation is particularly serious in Chinese primary and secondary schools. International research has rarely mentioned the concept of academic burden, which is mainly described in other similar concepts, such as academic burnout, academic stress, academic depression and academic anxiety. In addition, studies in other countries have paid more attention to the negative influence of academic load on students’ body and mind. Based on international perspective, the paper clarifies the somatic and psychological symptoms, behavior and attitude symptoms and symptoms of academic burnout caused by heavy academic burden, analyzes the influence factors of academic burden, and compares the function and applied scope of inventories and scales for academic burden. Findings enlighten us to focus on the teaching situations and students’ nature, increase empirical research and quantitative research of academic burden, put forward evidence-based, operational and pragmatic strategy of alleviating academic burden.
基础教育学业倦怠在全球范围内不同程度地普遍存在,在我国中小学尤为严重。国际研究很少提及学业负担的概念,主要是在其他类似的概念中进行描述,如学业倦怠、学业压力、学业抑郁、学业焦虑等。此外,其他国家的研究更多地关注学业负担对学生身心的负面影响。本文基于国际视角,梳理了学业负担过重引起的躯体与心理症状、行为与态度症状和学业倦怠症状,分析了学业负担的影响因素,比较了学业负担量表和量表的功能和适用范围。研究结果启示我们应关注教学现状和学生的本质,加强对学业负担的实证研究和定量研究,提出循证、可操作、务实的减轻学业负担策略。

Wei Gao, Xiaoguo Chang
Locating in the northernmost region of China, the Arctic Village of Mohe County is enlisted as one of the most charming tourist attractions of China for the unique resources and landscapes, such as “northernmost location”, magical astronomical phenomena and arctic ice-snow. However, it failed to explore domestic and foreign markets yet due to the poor promotion of government, thus resulting in the low consumer brand recognition. Combining with existing tourism resources in the Arctic Village, this study proposed an appropriate product planning based on the national promotion of “ice-snow tourism”. Meanwhile, great efforts were made to the propagation and publicity of the brand to improve brand influence of the Arctic Village. The ice-snow resources in surrounding region were integrated to promote the tourism development in the whole Heilongjiang Province.
漠河县北极村位于中国最北端,因其“最北端”、神奇的天文现象、北极冰雪等独特的资源和景观,被列为中国最具魅力的旅游景点之一。但由于政府宣传不力,未能开拓国内外市场,导致消费者品牌认知度较低。本研究结合北极村现有旅游资源,在国家推广“冰雪旅游”的基础上,提出相应的产品规划。同时,加大品牌的传播和宣传力度,提升北极村的品牌影响力。整合周边地区冰雪资源,促进黑龙江省旅游业的发展。

Ningxia Yin Et al.
Advanced cooling technology is a crucial measure of thermal dissipation for high-speed end-milling. In order to get an appropriate cooling technology and decrease the negative effects of traditional wet cutting, internally cooled cutting has been paid more and more attention. Because of interrupted cutting and uneven force, there was few application and investigation on internally cooled end-milling. In the paper, the effect of the end-milling tool with different internally cooled channel structure has been researched by experiment and theoretical analysis. The experimental results indicate that the end-milling tool with double helix channels carried out best machined surface quality. And the experiment result was also been analyzed and explained by computational fluid dynamics simulation, which provides a basis for the applying of the high-speed internally cooled end-milling tool.

Hot Analysis and Development Trends of Technology Transfer Research in Universities At Home and Abroad 国内外高校技术转移研究热点分析及发展趋势
Pub Date : 2021-07-29 DOI: 10.17762/converter.261
Xiaolan Wang, Wenhao Ying
In this paper, Citespace was used to perform bibliometrics analysis of 3437 journal papers in the field of technology transfer research from 1985 to 2020 included in WOS and CNKI database. The results showed that the quantities of relevant literature on technology transfer in domestic universities has been developing gradually since 2005 and drives to maturity stage. From the perspective of research institutions, Tsinghua University has become an important institution in the field of technology transfer research in colleges and universities. Developed countries such as the United States, Britain, Germany and Italy are still the dominant subjects of technology transfer in colleges and universities, but China has surpassed Germany and Italy and become a major front for technology transfer research of universities. Future research emphasis of technology transfer of universities in China is still mainly about technology transfer performance,academic entrepreneurship, and patent. It is of great significance to promote the internationalization of technology transfer to give full play to the advantages of domestic first-class universities, actively conduct interdisciplinary studies and optimize the external environment of technology transfer.
本文利用Citespace软件对WOS和CNKI数据库中1985 - 2020年3437篇技术转移研究领域的期刊论文进行文献计量学分析。研究结果表明:2005年以来,国内高校技术转移相关文献数量呈逐步增长趋势,并趋于成熟。从研究机构来看,清华大学已成为高校技术转移研究领域的重要机构。美、英、德、意等发达国家仍是高校技术转移的主导主体,但中国已超越德、意,成为高校技术转移研究的主要战线。未来中国高校技术转移的研究重点仍主要集中在技术转移绩效、学术创业和专利三个方面。充分发挥国内一流大学的优势,积极开展跨学科研究,优化技术转移的外部环境,对推进技术转移国际化具有重要意义。
