播种机参数和打穴铲结构对投种影响的计算机仿真 总被引：4，自引：2，他引：2
根据铲式成穴器与倾斜圆盘勺式排种器组合设计成的打穴播种机的结构特点,建立了种子下落过程中运动轨迹的参数方程。以此为基础分析了播种机双向倾角、排种器投种角和打穴铲结构参数对种子在打穴铲内自由下落过程的影响,进而确定了打穴铲几何尺寸的设计原则。 相似文献

Mince produced from Pink salmon (Oncorhynchus gorbuscha) was divided into 4 batches. A different commercial phosphate-treated gel-forming ingredient was added to each of three batches and the fourth batch was left untreated as a control. The mince batches were adjusted to a pH of 6.8 prior to freezing. The additive treatments were at 1, 2, 3, 4, and 5 percent of the final product weight. Samples were stored at -40°C for a period of 4 months and then measured for gel-strength by punch test, torsion test, texture profile analysis (TPA), and water binding ability (WBA). The textural properties of the mince were significantly improved by the addition of gel-forming additives. A difference in textural properties was detected among the standard methods of measurements, with torsion testing yielding the most sensitive measurements. 相似文献
