●汽车厂商盯上大城市以外驾车者,希望向其销售价格较低的车型中国购买的电动汽车数量超过任何其他国家,而大多数销售是在北京和上海等大城市。那里的电动汽车购车者有能力花30万元(约合4.3万美元)买一辆特斯拉Model 3这类的轿车。特斯拉(Tesla Inc.)在中国的竞争对手之一的董事长方运舟想的却是另外一群客户:生活在富裕程度低一些的小城市,甚至是农村的农民。他说:“我们的目标是为整个市场提供真正可负担的产品,而不是有钱孩子的玩具。”

Insect pest damage to crops is a threat to global food security(Tilman et al.,2011).Climate change,the evolution of insecticide resistance,and the phasing out of insecticides due to environmental and safety concerns exacerbate this *** urgently need safe and effective crop protection tools to sustainably generate yields that meet ever-increasing global demand.

利用数字图像分析土壤表面裂隙的方向分布

土壤与环境 2001年第1期10卷 45-46页

作者：李德成 bruce VELDE JEAN-FRANOI DELERUE 张桃林中国科学院南京土壤研究所南京210008 LaboratoireofGéologie

利用二维数字图像方法研究了在土壤干燥过程中表面裂隙方向分布的演化状况。结果表明，随着干燥过程的持续，裂隙的长度、宽度、面积和分数维均趋于增加，但裂隙的方向分布则逐渐趋向均匀。

Based on analysis of parameters of cores taken from Gaoyou Lake, including magnetic susceptibility, grain-size characteristics and sedimentary rate, environmental changes during the modern period were examined with the assistance of historical records and Gaoyou Lake water level materials. It is concluded that during the modern period a higher value of magnetic susceptibility and a lower sediment grain size coincided with a wet climate, while a lower value of magnetic susceptibility and a higher grain size were related with a dry climate. The results indicate that the climate in the 123 years period from 1880 to 2003AD can be divided into four stages： two low water level stages （1880-1915AD, 1948-1981AD） and two high water level stages （1915-1948AD, 1981-2003AD）. It appears that the regional climate generally underwent a dry-wet-dry-wet pattern in 30-year cycles. At present, it is at the end of a wet period, so the regional climate is expected to become dry in the near future. This conclusion corresponds with the climate records in the historical literature of the Gaoyou area, and it also matches with the climatic changes in North Jiangsu area.
