The effect of yield increasing bacteria on oat fresh grass product was studied by seed dressing and spray administration in a bi factor random sampling block test. 采用增产菌拌种、喷施2种方法的二因素随机区组设计,对燕麦草的增产效应进行了研究。
Based on the performance degradation mechanism of aerospace product and the small sampling characteristic of field test, a model in terms of Normal-Poisson process is proposed. 结合航空航天产品性能退化的机理与现场试验小子样的特点,建立了基于Normal-Poisson过程的性能退化模型。
