组织学检查：见9周后右侧牵张区形成新生骨质，符合膜内成骨，传送盘与近中牵张区形成骨性连接；左侧由于骨传松盘离开缺损区，牵张区与缺损区形成一较大的凹陷，未见明显新骨形成。

The proliferating cells were mainly distributed in the peri-chondrium and the peripheral zone of tracheal cartilage. The senescent chondrocytes were distributed in the central zone whereapoptotic morphological characteristics obviously appeared, such as pyknosis, karyorrhexis.

结果：软骨细胞呈现多种方式的无丝分裂像；气管软骨膜与软骨周围带多见细胞增生；气管软骨中央带多见衰老的软骨细胞，并见明显核固缩、核碎裂等细胞凋亡形态学特征。

Activities in the activity zone was an important component of the kindergarten children's day activity. The kindergartener's observation on the activity zone was the premises to practice effective guidance. The proper way and view angle should be chosen.

活动区活动是幼儿一日活动的重要组成部分，教师对整个活动区的观察是实施有效指导的前提：要选择适宜的观察方式和恰当的观察角度。

Through the work of the engineering and hydrology geology investigating, geologic structural planes investigating, acoustic test and deformation monitoring, and study on distribution rules of geologic structural planes, damage modes of slope, scope of loose zone, deformation rules with FLAC3D numerical simulation, the engineering proterties of loose zone is knowledged.

通过对金堆城深凹边坡松动岩体进行工程地质和水文地质的调查、节理裂隙调查、声波测试、变形监测等现场工作，研究了边坡结构面分布规律，边坡潜在的失稳模式，松动范围，变形规律，结合FLAC~(30)数值模拟，基本认识了金堆城深凹矩形边坡松动岩体工程特性。

The results show that the toughness of over-heated zone increased greatly because of austenite film lying in lathy martensite and a few ferrite.The toughness of fine grained zone decreased due to many factors,such as acicular martensite,a small quantity of austenite film,carbide separation and so on.

结果表明，10Ni8CrMoV这一新型钢种的模拟焊接热影响区的过热区和细晶区表现出与绝大多数材料完全相反的规律，过热区存在少量的铁素体组织，马氏体板条束之间形成了一定量的奥氏体薄膜，这些韧度相的存在使得过热区的冲击韧度与基体相比有了较大的提高；细晶区部位奥氏体含量很少，细小的板条马氏体端部呈针状特征造成应力集中，易于诱发裂纹。
