Dear Editor,Respiration is a vital and continuous physiological process depending on the output from spinal respiratory motoneurons to excite the inspiratory pump muscles[1-3].In mammals,phrenic motoneurons and intercostal motoneurons are the main spinal respiratory motoneurons,which innervate the diaphragm and intercostal muscles(IMs),respectively[4].

In November 1992 to February 1993 (IOP TOGA -COARE), many aerosol samples, rainwater samples and dry depesition samples were collected on the vessel Xiangyanghong No. 5 in the ocean area of IOP (2°S, 155°E). The time variations of concentration of crustal elements, sea salt elements are not very large. The dry deposition fluxes of crustal elements are related to the sources of air flows. According to the aerosol samples collected in the western Pacific Oceanduring eight cruises under the China-U. S. joint TOGA project from December 1985 to July 1990 and the aerosol data collected in the Kuroshio ocean area from 1987 to 1991 (China-Japan Kuroshio joint-investigation), seasonal average dry deposition fluxes of crustal elements, pollutant elements and sea-salt elements are calculated. It is found that the dry deposition fluxes of elements Fe, Co, Zn and Sb have their highest values in spring in the Kuroshio ocean area because of the influencing of Asian dust-storm. But in the western Pacific ocean they reach the highest values in autumn. In the

temporal variations and geographical distributions of sensible and latent heat fluxes over the Pacific were calculated and analyzed by using the Goddard Earth Observing System (GEOS) - four-dimensional Data Assimilation System (DAS). The calculated results showed that the heat flux over the northwestern Pacific varied obviously with seasons, but over the other ocean areas of the Pacific O cean there were no such phenomena. There was always the highest Value region of latent heat fluxes over the Pacific Ocean, but the values of sensible heat fluxes were often very small except over the ocean area north of 20°N and there was not highest value region at all. The latent heat fluxes had different distribu tions with longitude in different latitudes. And the variations of latent heat fluxes with latitude were not the same in different longitude and also it varied with seasons.

文化缺失与语言的濒危——以站人、站话为例

语言是文化的物质载体,语言濒危对人类文化的保存与传承会造成巨大影响;文化是语言的精神家园,文化的缺失对一种语言或方言走向濒危极具内部杀伤力,会加快濒危的语言走向消亡的步伐。本文在对黑龙江站人及站话考察过程中发现,作为一种独特的文化景观,站人源于站丁,清以后驻守在黑龙江各驿站的站丁的主体是由清政府发配而来的吴三桂手下的降兵,这些被烙上了“红字”的站丁后来不仅形成了一个特殊的社群—站人,而且形成了由职业变体演变而成的通行于社群内部的交际工具—站话,久而久之站话变成了黑龙江方言中的一个特殊的方言岛。通过查阅大量历史文献以及对几个站人集中居住区的实地考察,我们发现站话目前正处于濒危状态,而站人社群文化的缺失是导致站话濒危的直接原因。
