次轴

So it is not easy to turn this idea into reality. We creatively give our parameterization by using the expression of the blending surface in affine coordinate system ([9]) and the plane pencil together.

在仿射坐标系下，二次有轴曲面的表达式相对简单，我们基于厉玉容[9]给出仿射坐标系下拼接曲面的表达形式、不分块直接对混合拼接曲面进行参数化。

Research shows that the main factors influencing forging penetration efficiency are reduction in pass and the dip angle of the hammer, and the main factors influencing forged piece surface quality are axle feeding speed and rotation angle.

研究表明：影响锻透性的主要因素为道次压入量和锤头倾角；影响锻件表面质量的主要因素为轴向送进速度和旋转角度。

In this species, the first division of zygote produces two equal hemispheric cells by the first partition wall at the right angles to the axis of the archegonium.

合子的第一次分裂面垂直于颈卵器的长轴，产生两个相等的子细胞，靠近颈卵器颈部的营养器官原始细胞和远离颈部的基足原始细胞。

Axes which are used by more than one tab statement are ignored after the first time.

被超过一个标签书使用的轴将在第一次后被忽略。

Based on the experiment, microstructure and mechanical properties of the material in heating area of Ti-6Al-4V alloy were further analyzed under multi scanning, and the microstructure transfers from small equiaxial αβ+ to large 'α martensite.

在工艺试验的基础上，本文进一步对多次扫描条件下Ti-6Al-4V钛合金的微观组织与力学性能进行了测试分析，结果发现经过多次扫描后扫描区的微观组织由细小的等轴αβ+组织向粗大的钛马氏体'α组织转变。

Through Hilbert transform, a signal's plane trace can be get. There are two frequencies in the tested signal, so the signal's plane trace may be looked as the track of the out pole's end when two poles rotate around parallel axles. Using the knowledge of motion synthesis in theory mechanics, a formula to describing the change of plane trace's step length and angle for two-frequency be get. So we may prolongate the tested signal's plane trace from the echo's initial arriving moment, and get a certain length of the signal's prolongation.

通过Hilbert变换可得到测试信号的平面迹线，测试信号中只含有两个频率成分，视为双频信号，双频信号的平面迹线相当于两连杆绕平行轴转动时外杆杆端迹线，利用理论力学中运动合成和瞬心知识，推导出双频信号平面迹线步长平方满足余弦线性复合函数，而迹线转角可视为线性变化，据此可对回波到来之前的测试信号平面迹线作延长，得到一定长度的信号延展段，信号延展段与实测段作差可得到一次、二次回波的第一个波峰值。

Through poising seismic records in the direction of space, this method avoids the assumption that multiple events are orthogonal to the primary events.

该方法通过在空间方向上对地震记录进行均衡，避免了多次波和一次波同相轴正交的假设条件。

As the rod reaches the 12 o'clock position, take your thumb off the spool, thus releasing it to feed line out as the casting weight flies out.and falls far short of what you were hoping for.

不要松开按住线轴的母指！，反复练习几次找找感觉。不要用太大劲，现在还不是该发力的时候。熟练了上面的步骤就开始你的第一次抛投吧。

Focal mechanism solutions of 4 events, for which required parameters are available, indicate left lateral strike slip faulting for 3 events and thrusting for one event.

结果表明，有 3次地震是左旋走滑断层活动，另一次地震是逆断层活动。地震震源机制解的P轴方向为NW SE和NE SW 。

Although now everyone talking about the use of a non-driving this new technology, but the major clients are interested in from more than 1 m width machine paper cards and membership card maker, and a narrow band paper cards and membership card producers on repeated printing long can adjust interest and not large, the major draws its inspiration from the price of the motor.

尽惯此刻大家都评论拔取无轴驱不静这项陈技艺，但感乐趣的次给客户来自不及1米幅宽的宽幅纸制卡和会员卡制作商，而窄幅纸制卡和会员卡制作商差轻双印不幼可无级调不静的乐趣并不大，故障次给来自于电机的代价。
