弦

The arc data interpolation error by secant, tangent and chord, and the smallest error by secant mode is analyzed in this paper. The relation between the maximum radial error and arc radius and approach step-length in the secant mode of arc data interpolation in CNC system is detailed.

在分析数控系统圆弧数据插补割线方式较切线、内接弦插补方式误差更小的基础上，讨论了数控系统圆弧数据插补割线方式中最大径向误差与圆弧半径和逼近步长的关系。

Arc sine x is an angle whose sine is x.

反正弦x是一个其弦为x的角。

Type 1, straight canister form, exterior submit 10 arris form, transverse 4 bowstring grain.

式1件，直筒形，外部呈十棱形，横向四圈弦纹。

This is best used with low aspect ratio kites.

这是最好用低展弦比风筝。

The best choice for beginners, as I judge, are 2 or 4 lines kites with low aspect ratio.

初学者的最佳选择，因为我判断，2或4线的风筝低展弦比。

This will be of great interest to graduates and researchers in the fields of particle theory, string theory, astrophysics and cosmology.

这将是很大的兴趣，毕业生和研究人员的粒子理论，弦理论，天体物理学和宇宙学等领域。

This will be of interest to graduates and researchers in the fields of particle theory, string theory, astrophysics and cosmology.

这将有兴趣的毕业生和研究人员的粒子理论，弦理论，天体物理学和宇宙学等领域。

For many years, my parents and I were at odds with each other on this issue.

几年来，我和我的父母对这个问题一点都不咬弦。

Also, you see these pegs? They are intended for arcanic strings to attach to... but they've been lost.

另外 你看到这些钉吗它们原先是预备要绑一些神秘的弦的，但是也已经失去

Objective The experiment copied the wiry pulse by hurting rabbits and internennous drop infusing noradrenalin in rabbits and dogs,using NX-3 multifunctional sphygmograph to note the change of the sphygmogram, analyzing the time domain parameters,and classifying them attributively. It is a benefiting research work for teaching Chinese Traditional Medicine pulse diagnosis, although for applying Chinese Traditional Medicine indication to developing new Chinese drug.

目的 本实验通过对家兔疼痛刺激和对家兔、犬静脉滴注去甲肾上腺素复制动物弦脉模型，使用 NX-3 型多功能脉图仪记录压力脉图，对脉图时域参数进行分析并进行脉象的属性归类，为中医脉诊教学，也为今后新药研发中加入中医脉诊指标作初步的探索。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
