1. It is shown that the corrosion resistance determinated by electrochemical tests agrees well with the results by atmospherical exposure. 结果表明:采用线性极化和电化学阻抗法对冷轧钢板耐蚀性评价与大气挂片实验结果吻合;
2. The shape and perigee of artificial satellite orbits shall continually variate due to caused by the atmospherical drag and the earth gravity. 人造地球卫星的轨道由于大气阻力和地球引力场等因素的摄动,其形状和近地点位置将不断改变。
3. It was effective to decrease temperature of the rubber plantation in summer, increase the atmospherical moisture content and water content in soil; 可降低胶园的空气温度,提高系统内的空气相对湿度,增加胶园土壤含水量;
