“なんだか”与“なんとなく”都是副词,在意义和用法上既有相同之处,也有不同之处。但是,在什么样的场合,其意义和用法相同,二者可以换用;在什么样的场合,其意义和用法又不尽相同,二者不能互换,却是一个十分复杂,难以掌握的问题。本文对这两个词在意义和用法上的异同做一探讨。 相似文献

在贯彻法定计量单位时,会碰到“质量”、“重量”这两个词的使用问题。尽管人们对这两个词很熟悉,但长期以来,由于种种的原因一直没有能严格地区分,故在实际使用中经常出现模棱两可和混淆不清的现象。这种现象不单在我国存在,在国际上也有类似的情况。因此,在贯彻法定计量单位时,应逐步澄清,才能比较顺利的解决历史上遗留下来的这一问题。重量一词在国际上也有不同程度的混乱,国际上对此也很重视,但是直到目前为止,对这一问题还没有找出一个妥善的解决办法。 相似文献

不久前,我到内蒙古大兴安岭林区采访,经常听到林区的领导和专家提到这样两个词:资源危困和经济危困。因为我对林区经济知之甚少,所以也就难以想象这两个词所概括的实际状况.在林管局领导的建议下,我来到阿尔山林业局采访.阿尔山林业局以其优美的自然风光和温泉著名,但是,自然美景却无法掩盖资源危困和经济危困给这里的领导和职工带来的忧虑.这个局1946年 相似文献

“生态”一词目前应用极为广泛。一方面说明了人们生态意识觉醒、环保意识增强,另一方面也存在着对“生态”一词的认识不足、误解和误用。中南林学院徐国祯教授从“生态”一词的由来、概念以及如何求得最佳生态关系谈了自己的看法。 相似文献

自《中共中央国务院关于加快林业发展的决定》(中发[2003]9号文件)出台之后,我注意到在这份被誉为“21世纪中国林业发展的纲领性文件”中,尽管“生态”是其中出现派生词组最多(达30多个)的一个词,却没有再出现以往同类文件中常有的“生态环境”一词。我还注意到,自该文件出台一年多来,“生态环境”一词出现在各种书籍、报刊、文件、领导讲话的频率大大减少。包括新近出版的全国人大原副委员长姜春云同志主编的《中国生态演变与治理方略》一书,也没有再出现“生态环境”这一提法。一个偶然的机会,我从朋友处得知,绿色中国杂志社社长兼总编辑黎祖交教授是国内第一个公开发表文章对“生态环境”的提法提出质疑的人。特别是在《中共中央国务院关于加快林业发展的决定》的形成过程中,作为专家,他曾应邀在一位中央领导同志亲自主持的有关座谈会上专门提出不要使用“生态环境”一词的建议,并得到了中央领导的重视和采纳。如今,“生态”一词已成为社会各界的热门话题,生态建设已受到党和国家前所未有的高度重视,但有人对“生态建设”的提法又提出不同意见。我想知道黎教授对此又有何见解?于是,我一边拜读黎教授的相关论文,一边从心底萌生出进一步请教黎教授的愿望。阳春三月的一天,我终于如愿走访了黎教授。于是 相似文献

在中国古代文化中,“蒲苇”是指“蒲”和“苇”两大类条形长叶的草本植物。按照现代植物分类学,“蒲”很可能是指香蒲科香蒲属、天南星科菖蒲属的植物,其种类较多,但多指香蒲Typha orientalis、菖蒲Acorus calamus、石菖蒲Acorus tatarinowii等;“苇”在我国古代文化中指芦苇Phragmites australis。从古至今,无论从食用到药用价值,从工业到生态价值,“蒲”和“苇”都产生了许多衍生效益,从典籍记载、诗词书画、神话传说、传统民俗等方面,详细阐述了“蒲”和“苇”在我国古代物质文明和精神文明发展过程中的文化内涵,并介绍了两者在营建现代园林水体和湿地景观中的应用。 相似文献

Australia's native forests are predominantly Crown land, managed by the States. Regional Forest Agreements between four of the States and the Federal Government (1997–2001) resulted in a 36% increase in the area of conservation reserves and a 15% decrease in area of multiple-use (including timber harvesting) forests. The limited acceptance of timber harvesting in native forests, together with the rapid expansion of hardwood plantations, has diverted research focus away from native forests. Recent events including a prolonged drought and two forest fires totaling more than 3 million ha should have stimulated research in native forests on the effects of fire on ecosystem processes, on the management of fire and on management of water catchments; fires, far more than logging, are shaping our native forests in recent times. In particular, the use of prescribed fire to reduce fuels has decreased. We argue that Australian research effort in native eucalypt forests is lacking in two key areas – the effects of fire on carbon storage in forests and soils, and on the management of water yield from forested catchments. The results of forest research are variously published in the scientific journals, and increasingly in consultancy reports to governments or a to a range of organizations and industries. The question of who does the harnessing of knowledge coming from the science of forest ecology is compounded by constant changes in both political and management arrangements. If forest science is to assume a greater role in politics and forest management in Australia, scientists must enter the foray, using the fighting words of politics rather than maintaining the protective mantle of neutrality. With research in native forests being continually downgraded at both State and Federal levels, we take a somewhat less than optimistic view about how well ecological sciences will be harnessed in the service of forest stewardship and sustainability in Australia. 相似文献

The insecticidal effect of low temperatures for the control of all life stages of two stored-product insects, Plodia interpunctella and Liposcelis bostrychophila, was evaluated under laboratory conditions. The temperatures tested were 0, ??5, ??10 and ??15 °C, and, at these temperatures, the insects were exposed for 2, 4 and 8 h and also for 1, 2, 3 and 7 days. Regarding P. interpunctella, the most cold-tolerant life stage was larvae, given that 2 days of exposure were needed for complete (100%) mortality at ??10 °C. Moreover, all larvae were dead at ??15 °C even after 2 h of exposure. Eggs of P. interpunctella were susceptible to cold, as mortality was complete after 7, 1 day, 2 and 2 h at 0, ??5, ??10 and ??15 °C, respectively. L. bostrychophila was by far less susceptible than P. interpunctella. For this species, adults were still alive even after 7 days at ??10 °C, while complete mortality was achieved only after 1 day at ??15 °C. Eggs of L. bostrychophila were the most cold-tolerant life stage, as survival was observed even after 3 days at ??15 °C. The results of the present study provide the first data set on which all life stages of P. interpunctella and L. bostrychophila are evaluated for their susceptibility to cold treatments in a standardized series of exposures and temperatures. These results are expected to further encourage the “real world” application of cold treatments for the disinfestation of durable stored-products. 相似文献
