  helical pairs
The b-subunit is an a-a barrel of six helical pairs.
      
On average, helical pairs with H-bonds are packed tighter and have more atomic contacts.
      
In addition, the total interhelical atomic contacts are also different for helical pairs with and without H-bonds.
      
Interhelical atomic contacts between helical pairs with and without hydrogen bonding.
      
Helical pairs with H-Bonds in general have much more atomic contacts, and are packed tighter.

For a spatial linkage or a robot mechanism with helical pairs (H), its analysis or synthesis system of equations can not be transformed into a system of polynomial equations by triangle alternate, so the multiple solution problem of this mechanism can not be solved by the accurate homotopy method. In this paper, an approximate homotopy method (AHM) is suggested and configuration problem of the spatial 7H linkage is first solved by AHM. The method of this paper is suitable for solving the multiple solution...

For a spatial linkage or a robot mechanism with helical pairs (H), its analysis or synthesis system of equations can not be transformed into a system of polynomial equations by triangle alternate, so the multiple solution problem of this mechanism can not be solved by the accurate homotopy method.

对于含螺旋副(H)的空间连杆机构或机器人机构,无法用有理化法将其分析与综合方程组化成多项式方程组,因而不能用精确同伦法求解这些机构的多解问题.本文提出近似同伦法并用该法首次解决了空间7H连杆机构的装配构形问题.本文方法适用于求解任何含H副的空间连杆机构或机器人机构的多解问题.
