For simplicity, the distance is established as any 6 in.(150㎜) length. Imperfections of this type usually occur in an aligned pattern, but no distinction is made between aligned and scattered patterns. Also, the distribution pattern may be of assorted sizes.</span></p> <p style="text-align: justify; line-height: 23px; text-indent: -53px; margin: 0px 13px 0px 53px; font-family: '굴림'; col <p style="text-align: center; line-height: 23px; text-indent: -53px; margin: 0px 13px 0px 53px; font-family: '굴림'; color: #000000; font-size: 15px;"><span style="text-align: center; line-height: 23px; font-family: '굴림'; color: #000000; font-size: 15px; font-weight: bold;">Table 4.
