由于考虑了恒星自转，我们得到的理论模型在WUMa型相接双星的观测周期-颜色图上的位置非常接近观测得到的上边界。

Since the stellar rotation is taken into account , our model is located very near to the upper boundary of period-color diagram which is obtained from observations of W UMa type systems .

通过对WUMa型相接双星ABAnd、AMLeo、AKHer和APLeo的轨道周期研究，我们得到它们的物质转移率约为10~（-8）M⊙／yr。

We obtain their mass transfer rate to be about 10-8 M o / yr by studying period variations of W UMa type systems AB And , AM Leo , AK Her , and AP Leo .

结合模型计算结果，对已知29个NCS系统作了统计研究，结果表明NCS系统与相接双星在演化上有很密切的联系。

Compared with the computations , a statistical study of 29 known NCS systems was made . Two future evolution traces were shown for NCS systems : one will evolve into contact ; and the other will get in detached and or semi-detached state .

此外，这两个相接双星的轨道周期还表现出了周期性的变化成分。和变化的黑子一样，轨道周期的这种变化，也可能是由磁活动引起的。

Moreover , the orbital periods of the two contact binaries show cyclical oscillations , which may arise from magnetic activities just as the dark spots do . 4 .

现今已知的许多激变双星，如新星、X-射线双星、Ia型超新星等等都是由相接双星演化而成。

在双星中有一类特殊的双星称为相接双星，他们的特点是两颗子星都充满洛希瓣，双星间可以发生双向的物质和能量交换，并形成公共包层。

One special kind of binaries is called contact binaries , which arc characterized by the components filling the Roche lobes . Thus , the exchanges of mass and energy can journey to and fro between the components and a common envelope is formed .
