中国人的自信从何而来

某所大学请我去演讲,我问了大学生一个问题:作为中国人,你有自豪感吗?大家一致回答,有!我问:那到底是什么让你产生这种自豪感的呢?有人回答是长江、长城,也有回答是经济的高速发展、5000年的文明、文字,奥运、火箭升空……我紧接着又问:假如清晨醒来,你突然发现自己变成了一个菲律宾人,你还会为自己感到自豪吗?或者,你变成了一个卢旺达人,生活在非洲,经历过种族屠杀,经常处于饥饿状态,此时,你还能够     

借助影视作品传播力 选用城市形象代言人 市民形象也是软实力

常常有这样的说法:巴黎人高傲冷漠,纽约人不守规矩,东京人彬彬有礼却拒人千里,香港人性子急、走路也要小跑……公众对于一个城市的形象,往往取决于市民的表现,就像一个国家的形象在一定程度通过国民形象体现出来。

温家宝总理5日在政府工作报告中说,08年中国单位GDP能耗比上年下降4.59%。面对成绩,人大代表们也指出,长期来看中国能源消费仍将稳步上升,短期来看扩内需过程中高耗能、高排放行业仍将保持一定的增长刚性,     

Influence analysis of gaseous absorption on “HY-1A” CZI data processing Simulation and correction for Rayleigh scattering

Besides ozone, oxygen and water vapour should be considered for their absorptive effects on ＂HY--1A＂ CZI data processing. First ,gaseous transmittances under various conditions are computed and analyzed for the band settings of this sensor. Second, transmittances under six standard atmospheres are approximated as functions of zenith angle, the water vapour transmittance is approximated as a function of water vapour content and zenith angle, and the ozone transmittance is approximated as a function of ozone content and zenith angle. Finally, taking Rayleigh scattering as an example, the influence of ignoring gaseous absorption when calculating TOA reflectance is analyzed, and the effect of applying the presented transmittance approximations to gaseous absorption correction for Rayleigh scattering in ＂HY--1A＂ CZI data processing is evaluated.     

A preliminary study of variations of the Changjiang Diluted Water between August of 1999 and 2006

A large area hypoxia has been already reported respectively by two interdisciplinary surveys off the Changjiang Estuary since summer of 1999 and 2006. The hypoxic zone shows distinct year-to-year variations. Observed oceanographic data are first analysized and reveal a big difference for the Changjiang Diluted Water (CDW) between these two periods. These great changes are related to the tremendous reduction of the freshwater discharge and variations of wind fields between these two years. It is also found that the monthly mean intrusion of Kuroshio and its branches has increased in the northern East China Sea (ECS), but decreased in the southern ECS in August of 2006 as compared with 1999 on the base of general circulation models. Then, the Regional Ocean Modelling Systems is applied to the East China Sea to evaluate the contributions and relative importance of impacts from the river discharge, wind forcing and open boundary data. Our simulations reproduce the phenomena that more fresh water extends northeastward in 2006 and forms a negative SSS anomaly to the northeast of the river mouth as compared with 1999, which is consistent with observations. The five group numerical tests suggest that the wind forcing dominates the CDW variations followed by the Kuroshio and its branches. The study implies important roles played by hydrodynamic processes on the variability of hypoxic zone in the study areas.

海藻可延缓气候变暖

日前,一只研究队伍乘英国皇家海军勘察船“忍耐号”在南极海域进行科考时有了新的发现：当冰山消融的时候,就有铁质颗粒被释放进海洋里,铁质颗粒是海藻的营养物质,海藻的生长能够吸收大量的二氧化碳,然后海藻沉入海底,将有害的温室气体在深海里羁留数百年。

我省地热资源开发利用方向

一、推广集约化新技术,提高资源利用率 （一）地热资源的梯级利用 为使地热资源长期为人类服务就必须推广集约化新技术,提高资源的利用率。地热资源在各行业利用的同时应大力开发高效利用集约化新技术,降低尾水排放温度,提高资源利用率,同时解决地热水排放对环境造成的污染问题。     

地中海东部泥火山结构中烃类气体的来源迁移以及在水体中的行为

在被动大陆边缘的陆地和海底环境,常常可以发现泥火山结构的存在。泥火山的喷发主要由于沉积物深部形成的高压所诱发,而这种高压主要是由过度的气体和水体压力的积聚引起。这种情况下,气体、水体和沉积物被活化,沿着沉积物（通常是断裂）向上迁移,形成泥穹丘。
