[求助] 求一段英译汉

FT-IR spectra for powder and extrudate samples have been shown in Fig.5 in range of 400-1400 cm-1 wave number.
Structural vibrations near the bands: 450, 540, 860, 1120 and 1225 cm-1 that are the ZSM-5 Zeolite specification, for both powder shape and extrudate is visible in Fig.5.
540 cm-1 band is related to stretching vibration of double five membered rings (D5R) in MFI network that are completely alternative which are connected along a, b, c axis or at the intersection of channels. Meanwhile around the 450cm-1 band, appeared peak shows bending vibration of T.O connection related to TO4 tetrahedral. 800 cm-1  and 1120 cm-1 bands are relevant to outside stretching symmetric vibrations and inside stretching asymmetric vibrations respectively.

粉末和挤出样本的FT-IR光谱如图5所示,波数在 400-1400 cm-1之间。
图5中,粉末和挤出物的结构性振动在属于ZSM-5沸石规格的450, 540, 860, 1120 和 1225 cm-1波段附近是可见的。
在MFI网络的双五圆环 (D5R)结构中,540 cm-1波段和弹性振动相关。在此结构中,a、b、c轴之间相互连接,或者在通道的交叉处,因此是可相互替代的。另外,在 450cm-1附近, 出现的峰值表明,T.O连接的弯曲振动与TO4 四面体有关。 800 cm-1 和1120 cm-1波段分别与外部对称性弹性振动和内部非对称性弹性振动相关。
