The effect of the tool composition on the friction and wear behavior was investigated,and the morphologies of the rake face and rear face of the tool cutting the steel in air and nitrogen were observed on a scanning electron microscope. It was found that the Al_2O_3/TiB_2 tool was dominated by adhesive and abrasive wear in low speed dry cutting; while in high speed dry cutting,the tool was characterized by oxidation wear. An oxide layer of TiO_2 was formed by way of the oxidation of the reinforcing agent TiB_2 at a very much high cutting temperature, which contributed to greatly reducing the friction coefficient and increasing the antiwear life of the tool.Such a friction-reducing and antiwear behavior of the oxide layer was enhanced with increasing content of TiB_2 in the tool composite. However,the tool showed a relatively poorer wear resistance in N_2 than in air, because N_2 acted to retard the oxidation of the TiB_2 and the formation of the oxide layer on the tool rake face.
结果表明:低速干切削时,Al2O3/TiB2陶瓷刀具的磨损机制主要表现为粘着磨损和磨料磨损;而在高速干切削时,刀具的磨损机制主要表现为氧化磨损,刀具表面经由氧化反应生成具有润滑作用的反应膜而起到固体润滑作用,从而使刀具的耐磨性能提高,随着TiB2含量和切削速度的增加,反应膜的减摩抗磨作用增强;而在切削区通入氮气时,由于刀具表面氧化膜形成受阻,刀具的抗磨能力有所降低。

The results show that nonlinear dry friction between mandril and tube conduces to the self excited vibration of tube and the drawing speed is the main factor which determines whether the mandril static balance is stable.
分析结果表明,抖纹产生的主要原因是芯棒与钢管之间的非线性干摩擦力导致芯棒产生自激振动;钢管的拉拔速度及钢管表面润滑层的好坏是决定芯棒的静平衡位置是否稳定的关键因素,提高拉拔速度可将干摩擦阻尼转化为粘性阻尼,同时也使拉拔速度远离临界速度,从根本上消除抖

Among various fruit-growing positions, compared with the abnormal lateral fruitlets, the normal central and lateral fmitlets had higher fresh weight, dry weight and total Ca, Mg, K content of single fruit, and bigger diameter, more vascular bundles, thicker xylem and bigger phloem vascular bundles area of pedicel, but lower content of Ca, Mg in pedicels.
结果表明,随幼果的发育,单个幼果重量和Ca、Mg、K含量呈增加趋势;与发育不正常的边果相比,发育正常的中心果和边果的鲜重、干重、果柄直径、维管束数目、木质部厚度、韧皮部维管束面积和单果Ca、Mg、K总含量较高,而以干重为单位的果柄Ca、Mg含量较低。
