1.Thus, PD part will not be exposed in subsequent technical steps so as to reduce possibility to introduce defects by subsequent processes.
这样，在其后的工艺过程中，PD部分就不会露出，减小了后续工艺引入缺陷的可能性。
2.In order to reduce possibility of LPG leakage accident, some suggestions were provided for design of LPG pressured tank (spherical tank).
从降低LPG泄露事故发生几率角度出发，针对LPG压力储存系统（球罐）的设计提出几点建议。
