A raw rubber for millable polyether polyurethane elastomer was prepared.
研制了一种新型的聚醚型聚氨酯生胶。
It indicated that the selection of sugarcane seedling could emphasize particularly on millable stalks and sugar content. Brinell impact hardness tester
说明有效茎数和甘蔗锤度对甘蔗实生苗的选择影响较大。锤击式布氏硬度试验机
The plant height, stem diameter, millable cane per clump, the number of clump and the brix of each sampled cane were measured at the harvest time.
取样的每个植株，收获前分别测定株高、茎粗、有效茎数、丛重和锤度。
Path coefficient analysis indicated that the positive direct effect of millable stalks on cane yield was bigger than those of plant height and stalk diameter.
通径系数分析结果，有效茎数对蔗茎产量的直接正效应大于株高和茎径；
