After fired at 1600℃, with the increase of zircon addition the bulk density of the samples increases while apparent porosity decreases. When zircon addition is 4%, the strength is the best, and the photomicrograph of the sample exhibits a densely packed microstructure, with larger and better developed grains of periclase and spinel. Meanwhile, the direct bonding of solid phases is reinforced.
在1600℃热处理下,随着w(ZrSiO4)的增加,试样的体积密度增大,显气孔率变小,试样力学强度在w(ZrSiO4)为4%时达到最大值。w(ZrSiO4)为4%的试样整体显微结构致密,固相直接结合程度提高;并且方镁石和尖晶石晶粒的晶粒尺寸粗大,晶粒发育比较完整。

Result Compared with the traditional shaping mode of fan type, the types of L and FI could significantly increase the leaf area and the average berry weight and the L type could significantly increase the chlorophyll content, stomatal conductance and Rubisco activity of leaves and increase the photosynthesis rate of leaves at last in the rapid growth period of berry; all the shaping types of L, FI and V could increase the average berry weight and the soluble solid content in fruit to different degree and decrease the of titrable acidity content in fruit.
结果]与传统的扇形整型方式相比,L型和FI型整型方式明显提高葡萄的叶面积和平均单果重;在果实迅速膨大期,L型还显著提高叶片的叶绿素含量、气孔导度和Rubisco活性,使叶片的光合速率显著提高;L型、FI型和V型整型方式均不同程度提高葡萄平均单果重和可溶性固形物含量,降低果实可滴定酸含量。
