大小不一 [
dà xiǎo bù yī]
They are not of uniform size.
- 门口放着至少12把雨伞,大小不一,颜色各异。
In the doorway, lay at least 12 umbrellas of all sizes and colors. - 五颜六色、各式各样的、大小不一的风筝像漂亮的小鸟在飞翔、跳舞。
Multicolored creations of varying shapes and sizes filled the skies like beautiful birds darting and dancing. - 另一种说法认为大小不一但质量相同的原行星盘就可能形成各自不同的系外行星。
Another version has it that large and small protoplanetary discs of the same mass may form exoplanets differently.
