The x-ray diffraction studies disclose that the crystal corresponds to orthorhombic system
The results above indicated that the semicrystalline Copolymers II-V had the chains similar to that of the polymer I (p-PEKEKK) to form the crystal that was included in the orthorhombic system
with the p-PEKEKK.
Then she illustrates seven specific crystal systems with examples, among them a monocline system with sucrose, an orthorhombic system
with polyethylene, a hexagonal system with magnesium, and a cubic system with acetylene.
The above results indicated that the polymers I to V had the chain similar to that of the PEKwK to form the crystal that was included in the orthorhombic system
with the PEKwK.
3) In the orthorhombic system
, the axes of the primitive, body-centered, and face-centered cells are labeled to obey a < b < c.
9[degrees] (211) , As shown in Figure 4, the WAXD patterns of the copolymers I-V with 60-100 mol% BPOBDP fundamentally bore the same number and site of diffraction peak of every crystal facecrystal plane in comparison with that of the PEKmK, which indicated that the polymers I-V had the chain similar to that of the PEK/mK to form the crystal that was included in the orthorhombic system
The MgMnSiO4 compounds belong to the orthorhombic system
with space group Pbnm(62) and the cell parameters: a=0.
The results above indicated that the semicrystalline copolymers II--IV had the chains similar to that of the polymer I (PEKEKK) to form the crystal that was included in the orthorhombic system
with the PEKEKK.
EMA] multilayers (25 m/Nm, 5[degrees]C) transferred by horizontal lifting method  formed two-dimensional orthorhombic system
, which exhibits two kinds of short spacing.
All the crystal molecular structures of c1, c2 and c3 belong to orthorhombic systems
, and only one molecular unit was observed.
