light heavy theory
解釋
輕重理論-
On the base of these theory calculations, we passivated the front - surface both of different surface doping concentration solar cells by a thin layer of thermally grown sio2. the results show that the in heavy surface doping concentration cell is lower compared to the cell in light surface doping concentration. the majority of improvement in comes from the emitter surface passivation
接著採用sio2作為鈍化膜，從實驗上比較了在不同表面濃度下單晶硅太陽電池的鈍化效果，結果表明在高表面濃度下其開路電壓比低表面濃度下的開路電壓低，這開路電壓的提高主要來源於降低了前表面復合。 -
Since kamen and vagena, many researchers have discussed it in theory and experiment method. the main content in this paper is to set forth the slamming press calculations in dnv rules, gl rules and lr rules and the requirements for slamming strengthened bow structure and some comparisons ; slamming strengthened bow structure design for a bulk is carried out using dnv rules, and comparisons among several design schemes is carried through when heavy loading draft status replaces light loading draft status in practice. the results from above have been applied in ship production ; it is significant for ship structure improvement latter to calculate slamming press with direct calculation method, and then to design bow structure with dnv rules
本文的主要內容是分別闡述dnv 、 gl 、 lr三種規范對底部砰擊壓力計算及底部砰擊加強結構設計的一般要求並進行一些分析比較：用dnv規范對某型船（ 27000t散貨船）進行具體的底部砰擊加強結構設計，並就實際生產中產生的重載吃水狀態改輕載吃水狀態而出現的幾種設計方案進行比較，其具體結果現已用於實際生產；用直接計演算法確定砰擊壓力，再用dnv規范進行底部結構設計，對於後續船的改進均有指導意義。
