3) degree of branching
支化度
1.
The various definitions for the degree of branching(DB)of hyperbranched polymers were reviewed and an improved definition was presented for the general ABg polycondensation system.

补充资料：起支
1.官署名。北宋承唐末五代之制，以盐铁﹑户部﹑度支三部合为三司。度支掌各种财政开支﹑漕运﹑供应全国费用等。"起支"即为度支的别称，亦指度支使。又用作"发放"解。
