They are not toxicological studies, which would involve analysing the animal tissue for toxic effects, or studies of other safety aspects such as the rate of horizontal gene transfer.
它们不是毒理学研究。毒理学研究涉及分析动物组织研究毒性作用，或其他安全方面的研究，如横向基因转移率。
The forging method with horizontal V-shaped anvils(HVA) was introduced to control fibrous tissue flow direction, to improve the anisotropy of mechanical properties of axial forgings.
应用一种新的锻造工艺——水平V形砧锻造法，通过有效控制锻件的纤维流向，改善了轴类锻件力学性能的异向性。
The forging method with horizontal V-shaped anvils (HVA) was introduced to control fibrous tissue flow direction, to improve the anisotropy of mechanical properties of axial forgings.
利用水平V形砧锻造法，通过有效控制锻件的纤维流向，改善轴类锻件力学性能的异向性，实现轴类锻件的等向锻造，创造普通锻造法无法达到的特殊锻造效果。
