【摘要】 通过调查研究建立了香蕉弄蝶着卵株率和卵密度之间的关系模型 ,该模型为Y =1 1 4 3 9-8 73 62x+2 0 41 5x2 和Y =0 0 3 46e6 9487x(其中Y表示卵密度 ,x表示着卵株率 )。通过检验 ,两模型拟合值和实测值相关性达极显著水平 ,模型成立。对模型的准确性和应用该抽样方法的工效进行了检验和比较 ,认为该方法是一种有效的估值手段更多还原

【Abstract】 Equations were developed to describe the relationship between the density of the banana skipper eggs and the percentage of the banana trunks on which those eggs were laid.The euqations are as follows: Y =1 1439-8 7362 x +20 0415 x 2 and Y =0 0346e 6 9487 x . Y and X represent egg density and percentage respectively.These equations are effective and precise in field tests.Rather than counting the number of eggs on banana trunks,much time and effort can be saved by using the model to estimate egg density.更多还原
