本文介绍了高分辨电子显微镜成象、电子衍射、光学衍射和计算机图形学等技术在ZSM-5和ZSM-11共生结构表征中的应用。特别是，一个特定的制备显示主要由ZSM-5骨架结构，但与单一的插入带的ZSM-11的平均间距约为。66沿沿着[100]。还提出了发生共生的证据，其中ZSM-5的一个板片与相邻的板片相关，使得其中之一围绕[001]轴旋转90 °。提出了这种共生的理想化原子模型。
The combined use of high-resolution electron microscopic imaging, electron diffraction, optical diffraction and computer graphics for characterizing intergrowth structures of ZSM-5 and ZSM-11 is described. In particular, a specific preparation is shown to consist mainly of the ZSM-5 framework structure but with single insertions of strips of ZSM-11 at an average spacing of ca. 66 Å along [100]. Evidence is also presented for the occurrence of an intergrowth in which one slab of ZSM-5 is related to an adjoining slab such that one of these is rotated through 90° around a [001] axis. An idealized atomic model for this intergrowth is proposed.
