《现代汉语词典》（第六版）的编撰结合了现当代语言科学发展的成果,在排序、选词、释义、引文上具有鲜明典范的特征。随着当代科技的进步,对照欧美词汇学发展的成果,《现代汉语词典》在选词、释义上出现了片面性、滞后性、高雅化、脱离生活等问题。这些问题的解决有赖于对先进的信息技术、语言学理论的吸收。从具体编撰实际上加以改进。 相似文献

本文从云南多民族,民族分布地域广,民族地区经济文化相对落后这一现状出发,通过对一些民族地区现代教育技术发展现状调研结果、存在问题的分析,作者认为,教育技术理论在云南这样多民族地区的实践离不开少数民族。与内地及发达地区教育技术的理论与实践相比,云南民族地区教育技术理论与实践有其特点、难度。作者同时认为云南民族地区教育技术理论与实践是迫切需要的,又是极其重要的,根据云南民族地区的特点,现代教育理论与实 相似文献

Conditioning-specific reflex modification (CRM) of the rabbit’s nictitating membrane response (NMR) describes changes in responding
to an unconditioned stimulus (US) when the rabbit is tested in the absence of the conditioned stimulus. Specifically, after
at least 3 days of tone-electrical stimulation pairings, responses to the US increase in size, especially at intensities weaker
than the training intensity. CRM is similar to classical conditioning in that it is a function of the strength of conditioning,
it can be extinguished, and it can be generalized from one stimulus to another. To compare CRM and classical conditioning
further, we conducted three experiments to examine the effects of US intensity (1.0, 2.0, and 4.0 mA) on CRM. CRM was weak
following conditioning with 1.0 mA and extremely strong following conditioning with 2.0 mA and 4.0 mA. The data suggest that
CRM is a function of US intensity and have implications for posttraumatic stress disorder, a disorder potentially modeled
by CRM. 相似文献

Fluid and electrolyte balance in elite male football (soccer) players training in a cool environment
There are few data in the published literature on sweat loss and drinking behaviour in athletes training in a cool environment. Sweat loss and fluid intake were measured in 17 first-team members of an elite soccer team training for 90 min in a cool (5°C, 81% relative humidity) environment. Sweat loss was assessed from the change in body mass after correction for the volume of fluid consumed. Sweat electrolyte content was measured from absorbent patches applied at four skin sites. Mean (?± s) sweat loss during training was 1.69?±?0.45 l (range 1.06?-?2.65 l). Mean fluid intake during training was 423?±?215 ml (44?-?951 ml). There was no apparent relationship between the amount of sweat lost and the volume of fluid consumed during training (r 2 = 0.013, P = 0.665). Mean sweat sodium concentration was 42.5?±?13.0 mmol?·?l?1 and mean sweat potassium concentration was 4.2?±?1.0 mmol?·?l?1. Total salt (NaCl) loss during training was 4.3?±?1.8 g. The sweat loss data are similar to those recorded in elite players undergoing a similar training session in warm environments, but the volume of fluid ingested is less. 相似文献

学生创新和实践能力考核在大学招生中的价值：美国“彩虹项目”的启示 总被引：1，自引：0，他引：1
“彩虹项目”是由美国大学委员会资助的大学招生研究项目,其目的是探索研究大学招生中考核学生创新和实践能力的必要性。研究结果表明测评这两项能力在大学招生中具有极其重要的意义和价值。增加这项评价有利于对申请学生的能力进行更加全面的考核,不仅可以提高对大学GPA的预测效度,而且可以削减由于弱势群体和其他学生在大学入学标准考试中的不同表现所造成的招生偏差,使招生更具有卓越性和公平性。本文扼要介绍和阐述“彩虹项目”研究的理论基础、考核创新和实践能力的内容、考试结果对大学GPA的预测效度以及在美国塔夫茨大学的实践经验。 相似文献

The Grains containing Oil Inclusions （GOI） data in currently gas/condensate-beating Jurassic and Cretaceous reservoir sandstones of Well Pen 5 （the Mosuowan area of central Junggar Basin, NW China） are generally greater than the empirical threshold line of 5%. This is consistent with the gas-condensate section originally containing a palaeo-oil column. In order to assess the origin of the oil trapped in the oil inclusion and its relationship to the free oil/gas-condensate, a detailed molecular geochemical study was carried out for correlation between the free and inclusion oils. The paleo oil is most likely sourced from the Lower Permian Fengcheng Formation, which generated hydrocarbons primarily during Late Triassic and the oils were later secondarily altered and dysmigrated along faults likely during Late Jurassic-Early Cretaceous. In contrast, the current reservoired oil/gas-condensate mainly derived from the Middle Permian Lower Wuerhe Formation, whose peak generation time last from Late Cretaceous even to the present. This paper showed that integrated oil-bearing fluid inclusion analyses have likely allowed a complex multi-phase charge history to be recognized and resolved with a high degree of confidence. 相似文献

基于事件分析法的国家创新政策对高新技术产业的影响分析 总被引：1，自引：0，他引：1
选取在深圳中小板上市的高新技术企业为样本,运用事件分析法分析了我国2006年以来创新政策中的税收优惠政策的颁布对公司市场价值的影响。与考察单个事件影响原理不同,此次研究的税收优惠政策为＂间断发生的同类事件＂,故通过对该类事件发生作用的事件窗口内的＂异常波动＂来衡量事件的影响作用。实证研究结果表明：税收优惠政策的颁布给深圳中小板上市的高新技术企业市场价值带来了正向影响。此外,以传统的石化产业和新兴的生物医药产业为例,研究创新政策对不同产业公司的影响差异。结果表明：税收优惠政策的颁布对不同产业的平均超常收益率和累积平均超常收益率影响趋势基本相同,均呈现出增长趋势;但相比而言,对新兴的高新技术产业影响更为显著。 相似文献
