提出了纤维状多糖甲壳素晶体结构的详细模型。结构测定是通过使用光学模拟仪器进行的，该仪器被证明是推导傅里叶变换、振幅符号和产生光学傅里叶合成的充分且快速的工具。甲壳素的新模型正确地解释了已知的化学和物理特性，包括红外吸收以及 X 射线数据，但由于衍射图样的分辨率有限，它只能被视为一个很好的近似值。多糖链的立体化学构型对纤维素的结构具有一定的影响。
A detailed model for the crystal structure of the fibrous polysaccharide chitin is proposed. The structure determination has been carried out by using an optical analogue instrument which proved to be an adequate and rapid tool for the derivation of Fourier transforms, signs of amplitudes and the production of optical Fourier syntheses. The new model of chitin accounts properly for known chemical and physical properties, including the infrared absorption as well as for x-ray data, but because of the limited resolution of the diffraction patterns it can only be regarded as a good approximation. The stereochemical configuration of the polysaccharide chains has certain implications for the structure of cellulose.
