改低船體 的英文怎麼說
中文拼音 [gǎidīchuántǐ]
改低船體
英文
cut down a ship-
Presents the steady - state programming with constant coolant average temperature and constant live steam pressure, an ideal programming for marine nuclear power plant ( npp ), under which, both the coolant average temperature and the live steam pressure of nuclear steam supply system ( nsss ) are constant when the steady state operating condition is varied, and points out that in comparison with the steadysate programming with constant coolant average temperature, the ideal programming can improve the overall operating performance of npp effectively, especially in low - load range, for instance, raise the heat efficiency of npp, decrease the operating noise of main coolant pump, and improve the conditions of design, operation and control of the secondary loop system
雙恆定運行方案是船用壓水堆核動力裝置的理想運行方案.在這種運行方案下，當裝置穩態功率變化時，冷卻劑平均溫度與蒸汽壓都保持不變，與通常採用的冷卻劑平均溫度恆定運行方案相比，有效地改善了核動力裝置的總體運行性能，特別是在低負荷運行時，可以提高裝置經濟性、降低主泵運行噪聲、改善二迴路系統的設計、運行和控制條件，這對于提高船用核動力裝置的運行可靠性和安全性具有實際意義In a situation that this imported product demand will also be improved further in the following several years, must optimize system this purchase, transport, load and unload, store, dredge competence of link of transporting etc., introduce the advanced idea and method on the materials supplies of expressway construction abroad, adopting more advanced modern material flow thought on the software, the pitch is provided and deliver to constructing ; develop performance excellent keeping the tank wagon warm with low costs on the hardware ; supply the barge special - purpose and in bulkly ; the special - purpose pitch shipping dock stores pot, etc. to equip, thus propose that the transport way in which our country imports the pitch is chosen, and use the economic technological demonstration method to carry on the demonstration of economic technology to these ways, therefore get our country out of and impor t the imagination of transporting way reform of pitch, propose and purchase and concentrate on and melt, transport in bulk to take the whole province or the whole country this supply platform and accord with international advanced transport suggestion of technology in unison
在未來幾年這一進口產品需求量還將進一步提高的情況下，必須優化這一體系在采購、運輸、裝卸、貯存、疏運等環節的水平，引進國外在高速公路建設的原材料供應上的先進思想和做法，軟體上採用較先進的現代物流思想，對施工瀝青進行配送；硬體上研製成本低、性能優的保溫槽車；專用散裝供應駁船；專用瀝青裝卸碼頭貯罐等裝備，從而提出我國進口瀝青的運輸方式選擇，並運用經濟技術論證方法來對這些方式進行經濟技術方面的論證，由此提出我國進口瀝青運輸方式改革的設想，提出采購集中化、運輸散裝化這一全省或全國統一供應平臺且符合國際先進運輸技術的建議。
