    本文对国产铝板在冷轧与退火后的极图以及冲盂与拉伸试验中所表现的各向导性进行了研究。试验结果指出,纯铝的冷轧织构确定为(110)[112]+(112)[111],该织构引起在冲盂试验中与轧向成45°方向处出现制耳。经500℃温度下退火后,较强的再结晶织构(100)[001]+(146)[211]与残留的加工缴构(110)[112]+(112)[111]同时并存,在冲盂时制耳由4个与轧向成45°的方向变为6个与靴向成30°,90°方向处出现。当退火温度达600℃时,再结晶织构(100)[001]则显著地增强,制可的数目又减为4个并在与轧向成0°,9°方向处出现。纯铝经冷轧后的表面织构为(100)[011],该织构系经过一过渡层逐渐改变至中心部分的(110)[112]+(112)[111]织构。在测定沿板面不同方向的拉伸性能中,发现经冲盂后制耳的位置一般与板料近似真应力,σ_R,最小的方向相符合。对于纯铝退火后的(146)[211]织构的形成问题也进行了讨论。

For all three types as shown in Fig. 1, we get the same speed relationship as follows: n_z=bn_o+(1-b)n_y n_o-Constant speed of main shaft. n_y-Control speed from some speed-varying mechanism such as friction disk or belt cone. n_z-Output varying speed for some definite ends. b-Numerical constant dependent on gear ratios, given in Tab. 3 for all the three different...

    Here is discussed the application of differential gear mechanism for variable speed control, particularly for varying bobbin speed of flyer frames. For all three types as shown in Fig. 1, we get the same speed relationship as follows: n_z=bn_o+(1-b)n_y n_o-Constant speed of main shaft. n_y-Control speed from some speed-varying mechanism such as friction disk or belt cone. n_z-Output varying speed for some definite ends. b-Numerical constant dependent on gear ratios, given in Tab. 3 for all the three different types. Straight lines are plotted as in Fig. 2 to show the above relationship for different values of b. In Fig. 3 is given the relationship of turning moments and turning speeds at different values of b. In Fig. 4 is given the directional relationship of the mechanical power trans. mitred in the differential gear mechanism. The conclusion is: When the required speed variation is within narrow limits, the use of differential mechanism can reduce the mechanical power transmitted by the speed-varying mechanism, thus increasing its sensitivity and accuracy of control. See equation (12).

    本文讨论粗纱机差动机构中周转轮系的应用——变速控制。对于图1中三种类型的周转轮系,可以得出统一的转速关系式: n_z=bn_o+(1-b)n_y 在图2中根据上式按下同的b值作出各直线以表示其间的关系。在图3中按不同的b值作出转矩和转速之间的关系图。在图4中表示出在各种情况下周转轮系和变速装置间的功率路线图。根据(12)式我们可以得出这祥的结论:当所要求的变速范围不大时,采用了周转轮系可以使通过交速装置的功率大为减小,因而增加变速控制的灵活性和准确性。

    This paper contributes to the problems of the unsteady flow in parabolic prismatic open channels with its resistance taken into consideration. In the paper we use the method of perturbation to find the analytical solutions of St. Venant's differential equations. The general analytical solutions of 1st and 2nd approximations have been given for one directional wave flow which propagates into the steady flow region. At the end of the paper the applicability -of this method in our problem has been studied....
