While it is usually impractical for the marshallate to measure blade weight directly by weighing the sword before the basket hilt, cross, or pommel weight is attached, the linear density of the blade (its weight divided by its length) can be estimated fairly easily by weighing the finished sword, locating the point on the blade at which it balances, and measuring the distance from the point of balance to the tip, from the point of balance to the hilt, and from the point of balance to the point where the additional weight (the basket hilt, cross, or cross plus pommel weight) is attached to the blade.
而这通常是不切实际的为marshallate来衡量的刀身Weight直接由称重剑前一篮子的Hilt ,交叉,或pommel重量是重视,线性密度的刀片可估计相当容易称重成品剑,定位点的叶片在它的结余,以及测量距离平衡点,以尖端性,从平衡点到极限和从平衡点以点的额外重量(篮子的Hilt ,交叉,或跨加pommel重量)是连接到刀片。

This study is to give a solution for the estimation of flash point for mixtures, the necessity for classification of flammable liquids. The traditional models for predicting flash point of mixtures usually by the activity coefficient approach. However, the parameters of activity coefficient were regressed from phase equilibrium data in the literatures. If there is no such parameter in literatures for the desired mixture, the model cannot predict the flash point oft hat mixture. Thus, this research aims at the improvement of deficiency of the flash point prediction models in the literatures by useing UNIFAC (Universal Quasi-chemical Functional Group Activity Coefficient) equation, Dortmund-UNIFAC equation and Lyngby-UNIFAC equation. In this study, we were aim at the prediction model for miscible mixtures.From the result, it is suggested to use different type of UNIFAC equation to estimast activivity coefficient in the predition of flash point for different mixture type.
易燃液体分类的主要依据参数为闪火点值,因此本研究目的为解决易燃液体中混合物分类时所面临到的闪火点值缺乏的问题,而在过去文献中所提出的闪火点预测模式会使用到活性系数,但这些模式使用到的活性系数均需要相平衡的数据以回归其所需参数,若所欲估算闪火点的混合溶液文献上未有相关参数,则无法有效利用闪火点预测模式估算其闪火点,因此针对文献中现有闪火点预测模式的缺点,利用描述液体混合物活性系数UNIFAC (Universal Quasi-chemical Functional Group Activity Coefficient)方程式、Dortmund-UNIFAC方程式和 Lyngby-UNIFAC方程式,建立发展一闪火点预测模式,而本研究以互溶溶液为对象。

Angular spectral is spectral value map formed by estimating semblable coefficients of fast and slow shear wave or the variation of amplitude ratio of fast and slow shear wave with times and angles at a specified space point based on semblable theory of fast and slow shear wave, the angle value of this space point at a given time can be got by picking the maximum of angular spectral; the study reveals that fast and slow shear wave with different polarization direction should be separated using different rotation formula, eight formulas of separating fast and slow shear wave using clockwise rotation and counterclockwise rotation have been derived, and gained energy assignment rule and phase coincidence rule, in real data estimation, the rotation formula used for separating fast and slow shear wave can be uniquely determined on the two discriminating rules. On the basis of semblable theory of fast and slow shear wave, the delay time corresponding to the maximum of semblable coefficients at a specified point in a given time window is the delay time of fast and slow shear wave, delay time section of fast and slow shear wave can be got by moving space point and smoothing time window. The vertical variation values of delay time of fast and slow shear wave reflect the effect degree of vertical fractured reservoir on fast and slow shear wave which is defined as anisotropic coefficient, and section map of anisotropic coefficient can be obtained.
角度谱就是利用快慢横波的相似性原理,在某一空间点求出快慢横波的相似系数或快慢横波的振幅比值随着时间和角度的变化而形成的谱值图,拾取其极大值就得到该空间点某一时间的角度值;在研究中发现分离不同偏振方向的快慢横波应该采用不同的旋转公式,推导出了利用顺时针旋转和逆时针旋转分离快慢横波的八个公式,并给出了能量分配准则和相位一致性准则两个判别准则,在实际计算中利用这两个判别准则能唯一地确定分离快慢横波的旋转公式;根据快慢横波的相似性原理,在某一给定点和给定时窗内最大相似系数对应的延迟时间就是快慢横波的延迟时间,随着空间点的移动和时窗的滑动就可以得到快慢横波延迟时间的剖面图;快慢横波延迟时间与慢横波传播时间的比值定义为裂缝密度,并求出了裂缝密度剖面图;快慢横波延迟时间纵向上的变化值的大小反映了纵向上裂隙层对快慢横波影响的大小,定义为各向异性系数,并求出了各向异性系数的剖面图。

During same arc of motion, distance traeled by point on surface of 22-mm head, I, is less than on 32-mm head,II. A-B is shorter than E-F, and therefore leer arm of frictional torque force is less with 22-mm head.
在相同的活动度内,22mm头表面一点的滑动距离比32mm头小。A-B小于E-F:因此22mm头的摩擦扭矩力臂较小。
