Ecological analysis of morphological and genetic variation revealed that:(1) The averages of morphological characters were significantly negatively correlated with WSF (2) Dominant frequencies of some RAPD loci were significantly correlated with WSF (3) The correlation between morphological variation and genetic variation was not significant (4) The cluster analysis based on morphological and genetic evidence supported that all population can be divided into three ecotypes: saltmarsh reed, freshwater reed and giant reed.

相关分析表明：种群内各形态特征的平均值均与水盐联合影响因子显著负相关，但种群内形态变异系数与水盐联合影响因子普遍相关不显著；种群遗传多样性指数与水盐联合影响因子相关不显著，但部分生境倾向型的RAPD位点的显性频率和来自等位酶分析的克隆多样性水平与水盐联合影响因子显著相关；形态变异系数与遗传多样性指数相关不显著，但相关系数均为正值。

Background— Primary ciliary dyskinesia is a recessie genetic disorder that is characterized by sinopulmonary disease and reflects abnormal ciliary structure and function. Situs inersus totalis occurs in 50% of PCD patients (Kartagener's syndrome in PCD), and there are a few reports of PCD with heterotaxy, such as cardioascular anomalies.

The hexapod stiffness, which is moveable platform stiffness relative to fixed base frame, generally, is a non-symmetric matrix. It can map the infinitesimal increments in the displacement and in the applied forces , representing the characteristics of forces/displacements in incremental form and relating to machine head displacements when subjects to externally applied force system. It is no doubt that the displacements will affect machine accuracy, especially with the tool under changeable load system.

六杆机构加工中心的刚度意味着输出端移动平台相对于固定基础平台的刚度，一般地，它是一个非对称的刚度矩阵，它将位移微小增量转换成微小力增量，表现了增量形式的力/位特征，关系到机床加工头受有外载荷系统时的位移，直接影响到加工精度，特别是变载荷系统下的加工精度。
