build up逐步建立, 增进, 增强,使增大
例句：The pressure on the enemy is building up.

5. The new mathematical formula is based on a 5-year analysis of how the drugs keep HIV in check.

base on使建立在…基础上,立足
例句：Action should be based on solid facts.
行动应有确凿的事实为依据。

6. Most of the progress in the HIV treatment field in terms of deciding which treatments should be used in patients has been based on empirical studies – trial and error clinical trials – in which different combinations are tested against each other.

例句：He thought of everything in terms of money.
他是从钱的角度来看每一件事。
trial and error反复试验, 从失败中找到解决办法

例句：He said he was a doctor; but later he turned out to be a cheat.
他自称是个医生, 结果证明他是个骗子。

come up with想出, 提出
例句：I hope you can come up with a better plan than this.
我希望你们能提出一个比这个更好的计划。

9. So if you really understand how well individual drugs and drug combinations work, it may be possible to figure out what is the simplest treatment that would be effective and that could be made more widely available

figure out计算出
