1·For the capacity of propeller turbine is often small, people pay little importance on the transformation of reducing capacity under specified co.

由于轴流定桨式水轮机容量较小，其在特定条件下的减容改造问题不易引起有关部门的重视，因而这项工作在国内外很少有人从事。

2·Turbine is widely used in production and many aspects of life, mainly for prime mover of power generation; it can also directly drive pumps, fans, compressors and other ship propeller.

汽轮机被广泛应用于人民生产、生活的许多方面，主要用作发电用的原动机，也可直接驱动各种泵、风机、压缩机和船舶螺旋桨等。

3·ZTU series of Turbine Propeller are used as cycle stirring devices for lying pulp chest in paper making industry to keep fiber in suspension and also well-distributed.

ZTU系列涡轮式推进器用于制浆造纸工业作为卧式浆池的循环搅拌装置。以使纤维保持悬浮状态，保证纸浆的组成部分在浆料中均匀分布。

4·There iss strong vibration in the draft tube of a Francis turbine or axial flow fixed blade propeller hydraulic turbine when the turbine is running on part loading.

混流和轴流定浆式水轮机在部分负荷下运行时，尾水管中常出现较为强烈的振动。

5·It will be noted that the emphasis in this book is on the turbo-jet engine and that no special part deals with the propeller-turbine engine.

应该指出，强调在这本书是关于在涡轮喷气发动机，并没有特殊的部分涉及与螺旋桨涡轮发动机。
