请教各位大神，ABS OSV规范关于挡货栏杆原文如下：
1.9 Cargo Rail
Where cargo rails are fitted on cargo deck, they are to have freeing ports allowing quick drainage of water
from the deck. Scantlings of cargo rail are to be not less than following:
i) Rail:
SM = 0.858bhs2 cm3 SM = 0.000452bhs2 in3
ii) Standing alone stanchion in way of deck attachment:
SM = 10.14bh2s cm3 SM = 0.00534bh2s in3
where
b = breadth of cargo deck, between cargo rails, in m (ft)
s = spacing of cargo rail stanchion, in m (ft)
h = height of cargo rail or mean height of cargo, if that is larger, in m (ft)
请问文中提到的SM是什么？该怎样理解？
