目的　研究护堤隔离沟改造钉螺孳生环境 ,消灭钉螺的效果。方法　以有隔离沟洲滩为试验组 ,无隔离沟洲滩为对照组。在两组外洲钉螺分布高程设置网箱 ,人工投活螺 ,比较钉螺产卵数量、幼螺生长发育状况、钉螺自然死亡率和感染螺密度 ,测量隔离沟区域洲土含水量 ,调查隔离沟沉积层各年间钙化螺密度。结果　试验组外洲无钉螺孳生。当东洞庭湖水位退至 2 5 m左右 ,对照组钉螺分布带洲土平均含水量 38.1% ,高于试验组 2 8.3% ;人工投活螺后对照组产卵数高于试验组 ;试验组幼螺出现率显著低于对照组和室内模拟现场。春季网箱外湖水中捞幼螺数 ,试验组显著低于对照组 ;网箱内秋季查螺 ,试验组钉螺自然死亡率 (77.92 % )显著高于对照组 (4 1.6 7% ) ;隔离沟淤积层内钙化螺筛洗 ,上层显著低于中层 ,中层又低于底层。莫河铺外洲对照组网箱内活螺密度、感染螺密度显著高于试验组。对照组外洲高杆植被生长茂盛 ,试验组外洲无高杆植被。结论　洞庭湖退水期间 ,植被被淹死 ,气温较高 ,隔离沟能迅速沥干洲土积水 ,改变了洲滩潮湿的环境。

Peterson.的文章中谈到了对于某些较长的 Bose-Chau.hu.i 码(以下简称为B-C 码),码参数的计算问题。他还针对二进制的情形,对码的长度 n.充分大的 B-C 码证明了“信息比例”趋于零。要确定比例,关键在于算出码的信息数字个数。但是,Peterson.只是给出了对于信息数字个数的估计,没有精确地计算出对于长度为 n.的 t-误差校正码中之信息数字个数。*** 针对这一问题,作了进一步的研究,
