There were some differences in influencing grain size between dl and dl-x ( t). The genes of dl and dl-x ( t) were tightly linked to genes of small rounded grain or had pleiotropism effect for small rounded grain. dl-x(t)影响谷粒大小与dl略有不同,但均与小粒基因紧密连锁,或是一因多效所引起的。
It shows that the lower moulding temperature, the higher shearing rate in a moderate staying time, the smaller, more symmetrical and more rounded grain. 试验表明:剪切速度越大,浇铸温度越低,静置时间适中时半固态镁合金浆料制备的镁板带组织的固相颗粒越细小、均匀、圆整。
