Talvez deva tentar algumas variações de ortografia:
decrease spacing » decrease replacing (Expandir a busca), decreases spreading (Expandir a busca), decreases weaning (Expandir a busca)
spacing pattern » spacing patterns (Expandir a busca), pacing pattern (Expandir a busca), stacking pattern (Expandir a busca)
decrease of » decrease in (Expandir a busca)
of decrease » or decrease (Expandir a busca), not decrease (Expandir a busca), _ decrease (Expandir a busca)
decrease β » decrease _ (Expandir a busca), decrease in (Expandir a busca), decrease at (Expandir a busca)
β decrease » _ decrease (Expandir a busca), α decrease (Expandir a busca), l decrease (Expandir a busca)
decrease to » decreased to (Expandir a busca), decrease toc (Expandir a busca), decrease the (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease of decrease β decrease ) OR ( decrease to decrease spacing pattern ))~.
