摘要：
燃气轮机的叶片主体(51)具备：第一冷却通路部(58)、第二冷却通路部(59)、柱部(60)以及多个突出部。第一冷却通路部(58)设于靠近前缘(55)一侧。第二冷却通路部(59)设于靠近所述后缘(56)一侧。柱部(60)设于所述第一冷却通路部(58)与所述第二冷却通路部(59)之间，连续形成于所述叶片主体(51)的基部与端部之间。多个突出部从所述第一冷却通路部(58)的内壁面和所述第二冷却通路部(59)的内壁面突出。
摘要（英）：

A blade main body (51) of a gas turbine is provided with a first cooling passage part (58), a second cooling passage part (59), a column part (60), and a plurality of protrusions. The first cooling passage part (58) is provided at the side near to a leading edge (55). The second cooling passage part (59) is provided at the side near to a trailing edge (56). The column part (60) is provided between the first cooling passage part (58) and the second cooling passage part (59), and is continuously formed between a base part and an end part of the blade main body (51). The protrusions protrude from the inner wall surfaces of the first cooling passage part (58) and the second cooling passage part (59).
