Algorithm 如何假定螺旋参数？

有人能帮我理解什么样的准物质会有这样的螺旋吗

我不理解这个参数：旋转-螺旋的整体旋转。（'0'=无旋转，'1'=360度，'180/360'=180度）如果有人编写一些参数集（边、线圈、旋转）以获得螺旋，我将不胜感激

这是Matlab中的代码：

    clc 
clear all
centerX = 0
centerY = 0
radius = 10
coils = 30
rotation = 360
chord = 2
delta = 1

thetaMax = coils * 2 * pi;


awayStep = radius / thetaMax;

i = 1

for theta = (chord / awayStep):thetaMax; 


     away = awayStep * theta;


    around = theta + rotation;


     x(i) = centerX + cos ( around ) * away;
     y(i) = centerY + sin ( around ) * away;
    i = i + 1




    theta = theta + (chord / away);
    theta2 = theta + delta 
    away2 = away + awayStep * delta 
    delta = 2 * chord / ( away + away2 )
    delta = 2 * chord / ( 2*away + awayStep * delta )
     2*(away + awayStep * delta ) * delta == 2 * chord 
     awayStep * delta * 2 + 2*away * delta - 2 * chord == 0
    a= awayStep; b = 2*away; c = -2*chord

   delta = ( -2 * away + sqrt ( 4 * away * away + 8 * awayStep * chord ) ) / ( 2 * awayStep );

theta = theta +  delta;
end

v = [0 x]
w = [0 y]
scatter(v,w)

提前谢谢你
