一次曲管地温被误读1℃的判断与分析

在气象资料的收集过程中 ,仪器示度误读的情况时有发生。对有自记资料对比的气象要素 ,误读较容易及时发现 ;而地温误读则较难发现 ,要通过与前后几天相似天气特点的地温资料比较 ,误读才能发现。下面对一次曲管地温被误读 1℃的情况进行判断与分析。1　资　料南雄站 9月 1 6日地面温度和各层曲管地温资料 (表 1 )及前后几天的 2 0时地面温度和各层曲管地温资料 (表 2 )。表 1　南雄站 9月 16日地面温度和各层曲管地温资料 (℃ )2时 8时 14时 2 0时地面温度 2 1.5 2 5 .45 3 .12 7.4地面最高温度 5 6.85 6.35cm 2 5 .5 2 4.3 40 .13 1.810cm…

湖南地质遗迹调查史

从最开始的简单资料收集,到随着测绘技术发展后遥感等方式的介入,再到《湖南省地质遗迹调查报告》的诞生存即,湖南地质遗迹调查这项已经延续近30年的工作也在随着时代的发展不断取得新的突破。     

增强型12322地震应急信息服务系统

广东省12322防震减灾公益服务平台在2009年正式开通后,经过几次中小型地震的检验,系统暴露出很多不足之处,包括对现有资源的利用率不高、平台对专业技术人员和社会民众的服务能力不足等。通过改进系统现有的服务模式,提供更多实用的服务功能,如信息收集、短信群发、交互式服务和统计分析等,以便更好地服务社会民众,在应急事件中发挥更大的功用。     

Composition and distribution of fish species collected during the fourth Chinese National Arctic Research Expedition in 2010

There are awareness and concerns caused by the decreasing sea ice coverage around the Arctic and Antarctic due to effects of climate change. Emphasis in this study was on rapid changes in Arctic sea ice coverage and its impacts on the marine ecology during the fourth Chinese National Arctic Research Expedition in 2010. Our purpose was to establish a baseline of Arctic fish compositions, and consequent effects of climate change on the fish community and biogeography. Fish specimens were col- lected using a multinet middle-water trawl, French-type beam trawl, otter trawl, and triangular bottom trawl. In total, 36 tows were carried out along the shelf of the Bering Sea, Bering Strait, and Chukchi Sea in the Arctic Ocean. in total, 41 fish species belonging to 14 families in 7 orders were collected during the expedition. Among them, the Scorpaeniformes, including 17 species, accounted for almost one third of the total number （34.8%）, followed by 14 species of the Perciformes （27.0%）, 5 species of the Pleuronecti- formes （22.3%）, and 2 species of the Gadiformes （15.4%）. The top 6 most abundant species were Hippoglossoides robustus, Bore- gadus saida, Myoxocephalus scorpius, Lumpenus fabricii, Artediellus scaber, and Gymnoeanthus trieuspis. Abundant species var- ied according to the different fishing methods; numbers of families and species recorded did not differ with the various fishing methods; species and abundances decreased with depth and latitude; and species extending over their known geographic ranges were observed during the expedition. Station information, species list, and color photographs of all fishes are provided.     

Experimental study on the sampling efficiency of the whirl type separation sand sampler in a wind tunnel

A performance test was conducted in a wind tunnel by changing the principal configuration parameters of a sampler such as the diameter of the container, inlet width and cone height. The results show that the average sand collection rate is from 80% to 90% when any one of the configuration parameter levels is changed. However, the variation of a parameter level results in different ef-fects on the sand collection rate for each soil sample within a certain size range of sand grains. The results show that for various sand grain sized soil sample at each wind speed, the sand collection rate decreases when the diameter of the container changes from 50 mm to 40 mm, the sand collection rate increases by about 2%-3% when the inlet width changes from 10 mm to 8 mm, and the sand collection rate increases by about 3%-4% when cone height is altered from 100 mm to 125 mm. The average sand collection rate is enhanced by 2%-4% for the soil sample of different sized sand grains when the diameter of the container is 50 mm, the inlet width is 8 mm, and cone height is 125 mm.     

加强土地协管员队伍建设 助推国土资源管理工作

2008年,我局下发了在全县范围内聘任村级土地协管员的文件,经过乡村及基层国土资源所逐级审查,我们在全县19个乡（镇、办事处）组建了一支由245人组成的村级土地协管员队伍,建立了“局聘所管”的管理体制。经过一年来的任用和管理,这支队伍已经成为我县国土资源系统的重要组成部分。村级土地协管员在政策宣传、协助管理、信息收集等方面的作用得到了充分发挥,目前已经成为国土资源管理部门的好帮手,有力地推动了全县的国土资源管理工作。     

学术论文摘要的要求

在知识爆炸的今天,全面迅速地收集知识信息是人们追求的目标。文章的摘要高度浓缩了全文的知识信息,在信息收集的过程中往往起着关键性的作用,许多收集单位就只收录文章的摘要。所以,写好摘要无疑对知识的传播有着非常重要的意义。
