h an H-beam steel H形鋼條。 an H-Post H形電桿。 drop one's h's 不發h音〔如倫敦方言中把 hat 讀作'at 〕。 H hour 【軍事】發起攻擊的時間;特定軍事行動開始的時刻。 = 【電學】 henry; 【化學】 hydrogen; 【物理學】磁場密度 (intensity of magnetic field), 地磁水平分量 (the horizontal component of terrestrial magnetism); 〔表示鉛筆芯硬度的符號〕= hard(ness); 〔俚語〕heroin. H1 = 【化學】protium. H1+ = 【物理學】proton. H2 = 【化學】deuterium. H3 = 【化學】tritium.

In recent years , with the production of homemade h - section steel members , the above - mentioned factors have been well improved 近年來,隨著國產熱軋h型鋼投入生產后,情況得到了改善。
Wp = 6 > the practical table is compiled that integral stability coefficient of homemade rolled h - section steel beam under constant moment 編制了等端彎矩作用下軋制h型鋼梁式構件的整體穩定系數表,可供工程設計參考。
The suggestion is put forward that adopting the different geometry control condition between rolled h - section steel beam and general i - section steel beam 本文提出軋制h型鋼的幾何控制條件,并建議將一般工字形截面簡支梁和軋制h型鋼梁分列處理。
Based on the gb50017 code , the geometry control condition of integral stability capacity of homemade rolled h - section steel beam is conservative excessively and is modified accordingly 本文得出精度更高、適用范圍更廣的計算簡化式。 gb50017關于梁的整體穩定幾何控制條件對國產軋制h型鋼過于保守。
