采用邓肯多重极差检验法对两个苹果品种（Redspar和Delbarstival）的物理特性、力学特性、流体力学特性和营养特性进行了测定和比较。物理特性，例如：测定了两个品种的平均果实长度、宽度、厚度、几何平均直径、算术平均直径和等效平均直径、投影面积、表面积、球形指数、纵横比、果实质量、体积、真密度和含水量。测定了塑料、胶合板和镀锌铁的静摩擦系数、果肉硬度、破坏应力和弹性模量，测定了水动力学特性中的终速、上浮时间、弹跳力和阻力，测定了营养特性中的总干物质、总可溶性固形物、pH和可滴定酸度。结果表明，在1%的概率水平上，两个苹果品种的大多数性状存在统计学差异。
Several physical properties as physical characteristics, mechanical, hydrodynamic and nutritional properties of two apple varieties (Redspar and Delbarstival), were determined and compared using Duncan's multiple ranges test. Physical characteristics such as: average fruit length, width, thickness, the geometric, arithmetic and equivalent mean diameter, projected area, surface area, sphericity index, aspect ratio, fruit mass, volume, true density and moisture content, were determined for both varieties. The coefficient of static friction on plastic, plywood and galvanized iron, flesh firmness, failure stress, modulus of elasticity were found. The terminal velocity, coming up time, bouncy and drag forces, as hydrodynamic properties and total dry matter, total soluble solid, pH and titratable acidity, as nutritional properties, were determined. It was concluded that most of properties of two apple varieties was statistically different at the one percent probability level.
