definitive estimate

基本解释

Although the temperature estimate is not yet definitive, the hotter the surface temperature makes for a hotter interior, strengthening the chances of pools of liquid water inside the moon.
现在对温度的测量还不尽准确，越热的表面温度预示着越热的内部温度，这增加了土卫二内蕴含着大量液态水的可能性。
Consequently, the detailed estimate is often used as the budget estimate since it is sufficient definitive to reflect the project scope and is available long before the engineer's estimate.
因而，在工程师估算完成前的相当长时间里，只能用详细估算来作为控制预算，因为详细估算也能充分明确地反映项目的范围。
