6.a fraction whose numerator is an integer and whose denominator is an integer plus a fraction whose numerator is an integer and whose denominator is an integer plus a fraction and so on.
一个分数其分子为实数分母为实数加分数，分母中分数的分子也是实数，分母也是实数加分数，如此类推。
7.Fixed the mass of MMT,tensile strength,right angle tearing strength and elastic modulus of PVA/MMT/TiO2 composite fi lms raise as the increase of the TiO2 mass fraction and reach the max when the TiO2 mass fraction is 1.0%. But the elongation rate decreases with the increase of the TiO2 mass fraction.
MMT的质量一定时,复合薄膜的拉伸强度、直角撕裂强度和弹性模量随TiO2质量分数的增加而增加,并在TiO2质量分数为1.0%时分别达到最大值,但断裂伸长率则一直下降。
