材料专业外文文献中的两句话，求达人翻译！句子要通顺符合逻辑。

第一句：The main focus of this work will be the evaluation of the transition time to seizure for iron–copper bushes impregnated with h-BN micro-particles in transformer oil.

第二句：The effect ofthe PV (pressure–velocity) parameter on the transition time to seizure ofporous bearings with h-BN micro-particles under friction is studied in thiswork.
第二句修改下：The effect ofthe PV (pressure–velocity) parameter on the transition time to seizure of porous bearings with h-BN micro-particles under friction is studied in this work.翻译好的将追加悬赏。

第一句：The main focus of this work will be the evaluation of the transition time to seizure for iron–copper bushes impregnated with h-BN micro-particles in transformer oil. 句子解析：句子主语：The main focus of this work（工作主要焦点/中心）句子谓语：will be（将是）句子表语：the evaluation（评价，评估，估价，）句子定语（1）：of the transition time（过渡/转变/变迁/变革时间）句子定语（2）to seizure for iron–copper bushes（抓住铁铜轴套）句子定语（3）impregnated with h-BN micro-particles（包含H-BEN微例子的）句子定语（4）in transformer oil.（在变压器油/绝缘油中）句子整个意思：抓住对在绝缘油中包含H-BEN微离子的铁铜轴套转变时间的评估是这个工作的中心/焦点

第二句：The effect of the PV (pressure–velocity) parameter on the transition time to seizure of porous bearings with h-BN micro-particles under friction is studied in this work.句子解析：句子主语：The effect (效果/作用/结果/影响)句子表语：is（是）句子状语：in this work（在这个工作里面）句子定语（1）：of the PV (pressure–velocity) parameter（压力速度参数）句子定语（2）on the transition time（在过渡时间）句子定语：（3）to seizure（抓住）句子定语：（4）of porous bearings with h-BN micro-particles under friction（处于摩擦力下的含有H-BEN微粒子的多孔轴承）句子整个意思：抓住处于摩擦力下的含有H-BEN微粒子的多孔轴承过渡时间上的压力速度参数上的效果/影响，在这个工作中进行了研究.
