secondary block

The secondary fissure, located on the upfaulted block of the major fissure, has the normal fault property with north dip and north downthrown, and merges into the major fissure with Y-shaped distribution at depth 300-500m in Quaternary system.

次缝位于主缝上盘，具有北倾北降的正断裂性质，并与主缝断裂呈丫字型构造，在深度300～500m处的第四系内与主缝汇合。

For initiator B, when temperature is less than 180 ℃, MAH first reacts with secondary carbon of EB-block, secondly reacts with tertiary carbon; when temperature is higher than 180 ℃, the reaction rate of MAH reacted primary, secondary, tertiary carbon are similar.

对引发剂B，在温度低于180℃之前，仲碳原子最易发生接枝反应，其次是叔碳原子，当温度高于180℃后，伯碳原子、仲碳原子和叔碳原子的反应速率差不多。

The fourth-largest city, Wroclaw, cannot rival Warsaw for business buzz or Krakow for beauty; but its secondary schools have moved it into the "significantly above average" category in the Pisa rankings, well above Britain and Sweden, as well as former eastern-block rivals.

波兰第四大城市弗罗茨瓦夫在经济上比不过华沙，在美景上比不过克拉科夫，但他的中等教育已经远远超过pisa项目的平均水平，超过了英国和瑞典，也超过了前文提到的东方国家竞争者。

Within the block, 4 kinds of structural transformation modes were formed: thrust nappe structure, secondary shear structure, shear and flaser structure, and arc extrusion structure, thus reaching a transformation balance between active structures with different directions and different features.

在块体内部形成了挤压推覆构造、次级剪切构造、剪切压扁构造和弧形挤出构造等四种典型的构造转换方式，实现不同方向与不同性质活动构造之间的转换平衡。
