结果：冠心苏合丸系列组方可明显降低动脉血压，扩张冠脉血管及外周血管，增加冠脉流量，降低冠脉阻力；改善左室做功和心肌氧利用率，调整心脏血管的顺应性。结论：对心血管系统起到调整和改善作用。

Inner of high temperature is very easy to dock a place to the steel tube coating creation destroys welding because the operation is complicated and Asbestus rope heat insulation effect. Change in the area metallographic organization fever of arousing is affected and the remaining strain arouse strain corroding a dehiscence to create inner steel tube bringing about the ring oxygen powder series falls short of success. Carrying out a certificate is not a preferred plan.

此种方法由于扩口时的精度不高，现场施工环境和条件所限，很难达到预期的效果，加之操作复杂、石棉绳绝热作用的不充分性等引起的焊接高温很容易对钢管对接处的内涂层产生破坏，同时还引起热影响区金相组织发生变化、产生残余应力而引起应力腐蚀开裂，造成环氧粉末系列的内防腐钢管功亏一篑，实践证明不是最佳方案。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
