摘要：
The elastic modulus E1 of the crystalline regions of Tussah silk of Antheraea pernyi parallel to the chain axis was determined by X-ray diffraction. The E1 value was 20 GPa for both (0 0 2) and (0 0 6) reflections (c axis; chain direction), which is smaller than that of Bombyx mori (23 GPa). The small E1 for silk fibroin of A. pernyi is attributed to the large cross-sectional area of one molecule in the crystal lattice.
