深圳夏季沙面温度变化特征及天气对其影响的分析

利用大运会沙滩排球场馆自动气象站的气温、沙面温度(以下简称沙温)、降水等观测资料,分析了深圳夏季沙温在两类天气(晴天、雨天)条件下的日变化规律。结果表明:1)沙温受云况、降水影响很大,降水除了直接给沙面降温,还影响次日的沙温。2)晴天沙温日变化大,白天的平均沙温呈正弦曲线变化,一天中沙温最高的时段出现在12—14时,最高沙温可达62.9℃;夜间沙温呈现缓慢线性下降,且与气温差逐渐减小,在日出前后达到最低。沙温日最低值一般比日最低气温略高0.2—0.6℃;降水天气时,沙温日较差小,降水时段的初期或雨强突然加大,均能使沙温和气温同步骤降。

Response of Vegetation Cover to Climate Change and Influence of Dusty Weather in the Desertloess Transitional Zone of China

[Objective]This study aimed to analyze the relationships of the normalized difference vegetation index(NDVI)(1981-2006)in the desert-loess transitional zone of China with precipitation and temperature.[Method]The average method and the correlation function were applied in this study.[Result]The results indicated that during the growing season NDVI was positively correlated with precipitation in the current month,last month and the month before last,especially the last month.NDVI mostly negatively correlated with temperature,especially the temperature in the last month,which shows that the higher temperature,the more adverse the conditions for vegetation growth.[Conclusion]NDVI from August to October clearly is one of the significant factors influencing dust storm weather in spring of the next year.

Pharmacokinetics and tissue behavior of enrofloxacin and its metabolite ciprofloxacin in turbot Scophthalmus maximus at two water temperatures

Turbot Scophthalmus maximus, an important aquaculture species in China, currently suffers from epizootic diseases because of high density aquaculture. Enrofloxacin has been used to treat various systemic bacterial fish infections. However, studies concerning the pharmacokinetics of enrofloxacin in turbot are limited. In this study, the pharmacokinetics of enrofloxacin and its metabolite ciprofloxacin, were investigated in the turbot following intravenous and oral administration at 10 mg enrofloxacin/kg body weight, at 16℃ and 10℃ water temperatures. The concentrations of enrofloxacin and ciprofloxacin in the main tissues （plasma, muscle, liver and kidney） were detected by HPLC. The results show that the plasma concentration-time data for enrofloxacin were best described as a two-compartment open model after intravenous and oral administration. Three pharmacokinetic equations were established between the concentrations and temperatures. The kinetic profile of enrofloxacin was temperature dependent. The absorption half-life of enrofloxacin was 1.99 h and 2.17 h after oral administration, whereas the elimination half-life of the drug was 98.63 h and 136.59 h at 16℃ and 10℃, respectively. The peak concentration of enrofloxacin in plasma and tissues was higher at 16℃ than that at 10℃, and the peak plasma concentration time in the liver was the shortest at both temperatures among those of other tissues. The plasma ℃/MIC ratio varied between 11.08 and 5 540.00 at 16℃; and between 7.92 and 3 960.00 at 10℃. The AUC/MIC ratio was 467.82-280 690.00 at 16℃, and 359.48-215 690.00 at 10℃. These ratios indicate that it is possible to obtain therapeutic efficacy. Very low levels of ciprofloxacin were detected. The AUC ratios of ciprofloxacin and enrofloxacin in plasma suggest that plasma ciprofloxacin might play a minor role in enrofloxacin treatment for turbot.

Global influenza in cold phase of Pacific Decade Oscillation

Based on the study of the cold phase of the Pacific Decade Oscillation, pandemic influenza is related to climate. The relation of low temperature, Pacific Decade Oscillation, strongest earthquake, Influenza, hurricane and E1 Nino is researched in this study. In the cold period of Pacific Decade Oscillation, the strongest earthquake, hurricane with La Ni＇na, Pandemic Influenza with E1 Nino will occur stronger and stronger. From 1950 to 1976, the strongest dust-storm is connected with Pandemic Influenza one by one. So, dust-storm is one of factors to spread pandemic influenza viruses.

Effects of Temperature Gradient and Cooling Rate on the Formation of Methane Hydrates in Coarse Sand

Temperature gradient and cooling rate have an obvious effect on formation of methane hydrate. The process for formation of methane hydrate in coarse sand is monitored to tmderstand the relationship between temperature gradient and cooling rate and nucleation, growth and distribution of methane hydrate by using the electrical resistivity method. The results show that the change of resistivity can better reflect the nucleation and growth and distribution of methane hydrate. Temperature gradient promotes the nucleation, formation, and formation rate of methane hydrate. At a temperature gradient of 0.11℃/cm, the rate of methane hydrate formation and saturation reaches a maximum. Cooling rate has little effect on the methane hydrate formation process. Judging from the outcome of final spatial distribution of methane hydrate, the cooling rate has an obvious but irregular effect in coarse sand. The effect of tempera^re gradient on distribution of methane hydrate in coarse sand is less than that of cooling rate. At a temperature gradient of 0.07℃/cm, methane hydrate is distributed uniformly in the sample. If the temperature gradient is higher or lower than this value, the hydrate is enriched in the upper layer of sample.
