[求助] ZNO/聚合物制备光电器件

SANS measurement was carried out at the NG7 at the NIST Center
for Neutron Research of the National Institute of Standards and
Technology. Incident neutron wavelength of 6 Å , with varying
sample-to-detector distance of 1, 15 and 4.5 m detector 25 mm
offset yields a scattering range of 0.0009 Å-1< Q < 0.4 Å-1, where
q =4π/ λsin(θ/2) is the magnitude of momentum transfer vector,
and q is the scattering angle. After corrected for background and
detector efﬁciency, and converted to an absolute scale using direct
beamintensity, the 2D intensitywas circularly averaged to yield the
total structure factor, S(q) [42].

是不有误啊？前面的q为大写的，后面这个q该是θ？？

q=4π/λsin（θ/2）,前面是大写Q，后面θ是角度来的，π是圆周率3.1415926。。麻烦高手帮帮我吧，我将感激不尽啊。。。
