基於三角函數系的磁羅經自差校正方程Magnetic compass is one of directional navigation instrument in ship fitting, the deviation of magnetic compass will influence the navigational safety of ship
摘要磁羅經是船舶裝備的主要指向性航海儀器之一，磁羅經自差的大小將直接影響船舶的航行安全。Focusing on some disadvantages which exist in the training of measuring and eliminating deviation of magnetic compass in the labs of colleges, this article put forward how to develop a training system of measuring and eliminating deviation of magnetic compass, to build an integrated training lab so as to improve the ability of navigating officers in measuring and eliminating deviation of magnetic compass
針對當前院校在實驗室進行磁羅經自差測定與消除訓練中存在的一些弊端，提出開發研製磁羅經自差測定與消除模擬訓練系統，建設磁羅經自差測消訓練綜合實驗室，以提高航海人員對磁羅經自差的消測能力。Vanadium is important and valuable in steel - making, electronic production and national defence industry etc. now, the operation pattern of refining vanadium in our nation is based on human experiences, and the automation degree is still at a low level. operation mode based on human experiences is one of the main reasons make the quality of semi - steel and vanadium product unstable. in developed contury such as russian, static model was used to control the process of vanadium refining
我國目前的轉爐提釩為人工操作模式，由操作人員根據經驗和感覺進行操作，自動化水平低，存在著釩渣質量和半鋼質量不穩定的問題；在國外，俄羅斯等一些國家已經在使用靜態模型對提釩過程進行控制，取得了較好的效果，但是這些模型大都是根據復雜的物理化學規律研製的機理模型，要求有非常穩定的生產流程和工藝條件，對于鐵水成分、生產設備等變化的適應性差，不但移植困難，而且模型價格異常昂貴。分享友人
