摘要： A turbine nozzle comprises an array of nozzle blades (1) U disposed circumferentially in an annular passage (4) defined between inner and outer rings of a diaphragm and fixed to the inner and outer rings of the turbine diaphragm. The flow passage is defined between a pressure surface (F) and a suction surface (B) of adjacent ones of the nozzle blades, and a cross section of the flow passage includes predetermined ranges extending along a blade height (h) from the inner and outer diameter surfaces (hub and tip end walls) and defined by a curved line, and another range defined by a substantially straight line.

摘要： A process for preparing alkanolamines which comprises steps of reacting ammonia with an alkylene oxide in the presence of a carbonate of ammonia to obtain a crude alkanolamine solution, distilling off ammonia, carbon dioxide and water to regulate the content of carbon dioxide in the crude alkanolamine solution to 1% by weight or less, and distilling the crude alkanolamine solution to separate and collect the alkanolamines, whereby the production ratio of a monoalkanolamine can be increased and impurities can be decreased.
摘要翻译：一种制备链烷醇胺的方法，其包括在氨水存在下使氨与烯化氧反应的步骤，得到粗链烷醇胺溶液，蒸除氨，二氧化碳和水，以调节粗链烷醇胺溶液中二氧化碳的含量至1重量％以下，并蒸馏粗链烷醇胺溶液以分离和收集链烷醇胺，从而可以增加单链烷醇胺的生产比例并降低杂质。
