The sand skink is a small subterranean lizard that's virtually legless, and it swims through the sand - or just under the surface of the sand. And as it does so, it pushes up a little ridge of sand that falls down behind it, and it leaves these S-shaped curves.

沙蜥是小形的、地底下活动的蜥蝪，实际上没有脚(因为它的脚是像鳍一样推动前进而非行走)，在沙中或在沙下类似游泳前进，在它身后推挤出微小沙丘，留下s形的曲线。

In 1434 Shah Rukh installed Iskander's brother Jahan Shah as his Timurid governor in Tabriz.

A highly sensitive fluorescence quenching method for the determination of iron based on the system of iron-oxfloxacin-SDS has been developed. In NaAc-HAc medium, iron reacts with oxfloxacin and SDS to form a non-fluorescent ternary complex which can quench the fluorescence intensity of oxfloxacin.

在表面活性剂十二烷基硫酸钠存在下，铁能与氧氟沙星形成络合物而猝灭氧氟沙星分子的内源性荧光，使其荧光强度显著降低，据此，提出了铁氧氟沙星SDS体系测定铁的荧光分析新方法。

The experimental conditions were optimized to produce following results: good linearity of sulfamethoxazole, norfloxacin, ciprofloxacin, ofloxacin and tetracycline in the range from 1.00 ng/L to 1 000 ng/L and the limits of quantification 1 ng/L, the good linearity of terramycin and aureomycin in the range from 10.0 ng/L to 2 000 ng/L and the LOQ 10 ng/L, the recoveries of deionized water and surface water from 72.1% to 112%, and the RSD from 0.6% to 9.2%.

摘要〗采用超高效液相色谱-电喷雾二级质谱联用技术同时测定水中7种抗生素，优化了试验条件。磺胺甲恶唑、诺氟沙星、环丙沙星、氧氟沙星、四环素在1.00 ng/L ～1 000 ng/L 范围内线性良好，定量下限为1 ng/L ，土霉素、金霉素在10.0 ng/L ～2 000 ng/L 范围内线性良好，定量下限为10 ng/L ，去离子水和地表水样加标回收率为72.1%～112%， RSD 为0.6%～9.2%。

When coverage varying from high to low, the parameter a decreasing, and b increasing. The fitted regression equation between total vegetation coverage and runoff duration as following, C = 3.4881nt_p -11.772 (R~2=0.9477). The equation shows that the vegetation is positive correlation to duration, i.e.

高寒草甸产流、产沙的试验结果表明，不同植被盖度的嵩草草甸其产流、产沙过程可以用幂函数R=at~b分布来描述，随着盖度由大变小，方程参数a值逐渐变小，b值逐渐增大；而覆盖度在5％以下的黑土滩，其产流、产沙过程更符合指数函数R=ae~分布。

The Markov forecast model, time series method (triple exponential smoothing method and a combined of triple exponential smoothing method and Markov model) and stepwise regression forecast method were choosed, and the basic principles and processes of the three models were analyzed and compared. Based on above, the three methods were used to predict population dynamic of Cricetulus barabansis and Meriones unguiculatus. The characteristic, accuracy and applicability of three methods were analysed and compared. The results showed that,(1) Markov model belongs to a middle-long time forecast model, and the result was interval forecast, but it reached the requirement of forecasting the harmful population dynamic of rodents. Through the forecasted population dynamic of Cricetulus barabansis and Meriones unguiculatus in 2004, the results were accurate; this meant that Markov model was a good forecast model to Cricetulus barabansis and Meriones unguiculatus population.

选择马尔可夫链预测模型、时间序列分析法(三次指数平滑法、三次指数平滑法和马尔可夫链预测模型的组合预测法)和逐步回归预测法，对这三种模型的基本原理、模型的构建过程进行对比分析，在此基础上用此三种方法预测了黑线仓鼠和长爪沙鼠的种群数量，并对三种方法的特点、预测的准确度和适用范围进行了比较分析，结果表明：(1)马尔可夫链预测模型属于中长期预测，预测的结果为区间预测，但对于害鼠种群数量的预测来说已经达到要求，通过对2004年黑线仓鼠和长爪沙鼠种群数量的预测，预测的结果都比较准确，这说明对于预测黑线仓鼠和长爪沙鼠种群的数量动态，马尔可夫链模型是比较好的模型。
