age in days的用法和样例：
- The relationship between mouth width and fish age in days was expressed as: y = 0.2327e00682x (R2 = 0.9492).
- The relationships of total length, body length, and body weight to age in days were y = 3.2552e00472x (R2 = 0.9710), y = 3.3205e o.
- Feeding rate of larvae at 6 - 10 age in days under 1k - 2kLUX light intensity was highest at the range of 0.4K - 3K LUX light intensity, but it had not significant difference.
- Intermittently itinerant swimming behavior of larvae at 3 age in days was principal and then slowly truned to a totally itinerant swimming behavior at 7 age in days.
- The protein contents of the normal larvae decresed and the protease activity increased, the protease activity in intestine was higher than the protease activity in body without intestine from 9 age in days to 22 age in days.
- In days of yore, we lived in poor.
