As a result of the difference on protein quality, if cotton dregses of rice with the beans,not be two kinds of any raw material, unit protein uses value to the raise of the animal identical, use Pi Texun method consequently the appropriate price of the raw material that with respect to meeting overmeasure protein character needs.

由于蛋白质质量上的差异，并不是任何两种原料如棉粕与豆粕，单位蛋白质对动物的饲用价值完全相同，因而采用皮特逊法就会高估蛋白质品质差的原料的适宜价格。

Ransforming growth factor beta TGF-β is a potent growth suppressor of normal epithelial cells. However, many types of invasive cancer cells (e.g. breast cancer frequently overproduce TGF-β to enhance their growth and metastasis. Quite frequently, these cells do not possess a functional type II TGF-β receptor, indicating an aberrant TGF-β signaling is responsible for promoting cell growth.

Transforming growth factor beta 对於正常的上皮细胞是一个很强的生长抑制因子，然而，许多种具有蔓延侵犯性的癌细胞常常是表现大量的 TGF-β来促进细胞生长与转移，这些癌细胞通常不表现具有功能性的第二型 TGF-β receptor，显示有另类的 TGF-β讯息传递可以促进细胞生长。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
