角曲线

It seemed that segments must be short enough so that any curve that developed would be well defined, i.e., there should be some maximum angle between adjacent segments, perhaps 0.1 radians.

它 看来，部分必须太长，从而使任何曲线，发达国家将是很好的界定，也就是说，应该有一些最大角相邻部分，也许0.1弧度。

1The axial evolution law on the structure and the aerodynamic characteristics of the asymmetric flows around slender bodies of revolution at incidences is summarized:whether the flow asymmetry is powerless or powerful,the flow always appears in the structure that lee-side vortices rise,and shed vortices form,and new lee-side vortices come into being alternately on opposite sides of a slender body of revolution axially from nose apex downstream to afterbody,and always induces the sectional side force of waving quasi-sinusoidally downstream axially.

1总结出细长旋成体有攻角非对称绕流流场结构和气动力特性的轴向演化规律：无论非对称性强弱，沿轴向从头部尖顶往后体，非对称绕流总是呈现为左、右两侧背涡交替从物面向上飘起、形成脱落涡、再衍生出新生背涡的流场结构，并诱导出沿轴向呈类似正弦曲线形式振荡分布的截面侧向力。

Mean ApoL I of keratinizing types(15.77±4.34) was significantly higher than those of nonkeratinizing types (8.03±1.70). The ApoL I increased from 6.51±0.58 with poorly differentiated cancers through 10.58±2.90 with moderately differentiated cancers to 18.41±4.49 with well differentiated cancers. There was no apparent correlation between ApoL I and sex, age, tumor size, tumor location and tumor infiltrative depth. The Kaplan-Meier survival curves between ApoL I＜10‰ and ApoL I≥10‰ have significant difference, while the former has a shorter survival time.

角化型ApoL I高于非角化型(P＜0.01)；肿瘤分化越好，细胞凋亡越多，低度、中度、高度分化ApoL I有差异(P＜0.05)；不同性别、年龄、肿瘤部位、长度、深度，其ApoL I并无差异；以10‰为界将ApoL I分组绘制Kaplan-Meier生存曲线，ApoL I≥10‰组术后生存率高。

And analysis the output curve after improving, and in the same time, the difference in the corresponding angular speed, angular acceleration, angular displacement curve of the bilateral symmetry components will obviously decrease.

并分析改进后的输出曲线，在同样的时间段内左右对称传动构件相应的角位移、角速度以及角加速度之间的差异明显减小。

On the basis of the modeling and analyzing of the transmission system of the PQS-3-D elevator for car in the preamble, this article analysis the reason of the small difference of the angular speed, angular acceleration, angular displacement curve between the bilateral symmetry components. Actually, it is the result of that the torsional rigidity of the bilateral drive shafts are different, therefore has made the revision suggestion to the drive shaft parameter.

在对PQS-3-D型汽车专用升降机传动系统建模分析的基础上，分析左右对称传动构件的角速度、角加速度、角位移曲线在系统起动时间内有较小差异的主要原因，发现是由于左右传动轴的扭转刚度系数不同造成的，故对传动轴的参数做了修改建议。
