  1. Abstract : from a universal formula for calculating the attenuation cross section of particles in arbitrary shapes, exact expressions for calcualting the attenuation cross section of polydisperse, small spheroids, whose rotary axes are in specific status, have been derived. attenuation cross sections of both liquid and ice particles in different shapes at different wavelengths in microwave band have been computed and analyzed. the results are informative to microwave remote sensing of precipitation

    這種徑流過程代表下墊面和人類活動水準不變情況下氣候波動對徑流的影響，然後利用計算的長系列徑流過程與實測徑流過程對照，其差別反映下墊面的自然變化過程是十分緩慢的，可以忽略，因此這種差別主要代表了人類活動的影響，從前後期率定水文模型所得參數的差別及參數所代表的物理意義來分析下墊面及人類活動的變化，從而將氣候波動和人類活動對地表水資源影響程度定量分解出來。
  7. In this work, layered lini1 - xalxo2 ( 0 < x 1 / 2 ) solid solution materials were successfully synthesized by current co - precipitation method in the air, and their preparation and properties were deeply and systematically explored. influences of different factors on the structure and properities of samples were studied, including li resources, different performs, li / m ( oh ) 2 molar ratio, calcining heat condition, the best synthesis technics were concluded : sintered for 16h at 700 from li source ( lithium nitrate ) : m ( oh ) 2 = 1. 05 : 1, ultrasonic vibration for dispersing and catalysing are best. lini0. 8al0. 2o2 exhibited a discharge capacity of 130. 7 mah ? g - 1 in the voltage range of 2. 8 ~ 4. 40v and at a specific current of 0. 2 c. a new co - precipitation method was proposed, it included ultrasonic for dispersing and catalysing, by dropping lioh to the aqueous solution of metal nitrates, hydroxides of metals were precipitated and the resulting solution was evaporated as received
