粗晶粒状的

The result showed that toughness of coarse-grain zone in X70 grade steel pipe HAZ was weak.Coarse grain,granular bainite,high binate and other unbalance low temperature variation result in quantity increasing. In addition to,impact toughness of coarse grain zone decrease with the t8/5 increasing.

结果表明：粗晶区是X70级管线钢热影响区中韧性较差的区域，粗晶区韧性恶化主要是晶粒粗化以及粒状贝氏体、上贝氏体等非平衡低温转变产物数量增多造成的，且粗晶区的冲击韧性随着 t8/5 的增加而降低。

These jadeite jade specimens show mainly following texture types: granular crystalloblastic texture, equigranular crystalloblastic texture, inequigranular crystalloblastic texture, prismatic crystalloblastic texture, f...

主要的结构类型有粒状变晶结构(粗粒状、中粒状、细粒状及微粒状)、等粒变晶结构、不等粒变晶结构、柱状变晶结构、纤维状变晶结构、碎斑结构、交代结构、糜棱结构及碎裂结构等。

For the heat input of 8kJ/cm and preheated temperature of 60℃, impact toughness value of specimen was highest for the formation of fine grains and a certain quantity of granular bainite which can effectively partite lath bainite.

当采用8kJ/cm的线能量和60℃的预热温度时，粗晶区的晶粒较细，组织由板条贝氏体和一定量的粒状贝氏体组成，由于粒状贝氏体对板条贝氏体的分割作用，使板条贝氏体的长度较小，方向性差，表现的韧性最优越。

The effect of granular bainite on impact toughness of CGHAZ of Ultra-low carbon copper-bearing age hardening steel was studied.

研究了粒状贝氏体对超低碳含铜时效钢粗晶热影响区冲击韧性的影响。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
