n.偏菱形(斜方形；斜方六面體)

The basic form of this crystal is a rhomb. 此類晶體的基本形狀為一菱面體。

Two opposite corners of this rhomb contain three obtuse angles of 101°55'. 菱面體的兩個(gè)對(duì)頂包含著三個(gè)101°55'的鈍角。

This would be a bit more obvious if we cut the rhomb to have edge of equal axis. 若把斜方體的棱都切成等長(zhǎng)，就可以看得更清楚。

Its back is greenish grey while its body is silvery white with a black rhomb shortly behind the pectoral base. 牠的背部灰綠色，軀干大致銀白，胸鰭基部后方有一黑色菱形斑紋。

Currently the improved Fresnel rhomb and retangle prism compound rhomb phase retarders are the ideal and utility-type achromatic phase retarders. 結(jié)果表明改進(jìn)型菲涅耳菱體以及直角棱鏡組合型消色差相位延遲器，是目前較理想的實(shí)用型消色差相位延遲器。
