Objective : to introduce a new prefabricated post - and - core system , a helical drilling bit and a prefabricated post - and - core consisting of a root canal orifice bur which was designed by the author 摘要目的:介绍一种由螺旋型根管钻、自行设计的根管口台阶状车针、预成桩核组成的预成桩核系统。
There are two forms of nucleus in the e . carinicanda sperm : fibrous and vesicular ones the sperm ultrastructures of the p . trituberculatus and s . chekiangense consist of nucleus cup , radial arm , acrosome 2 .精子结构罗氏沼虾与脊尾白虾的精子结构相近,呈图钉状,由棘突、顶帽和精核组成。
Aad , it is due to the complicated geological structural environment resulted from the separation , merging , collision of plates which consists of land nucleus in geologic history , and it results in the multiple cyclic state of china s land nucleus development 而造成中国油气地质条件的复杂性的地质构造环境,则是在地史中各陆核组成的板块之间分合和碰撞,使得中国陆核的发展呈多旋回状态。
By means of sem , tem , laser scattered particle analyzer , etc . , the formation mechanism of ultrafine sio2 particle was studied . it was found that at the initial stage , the sio2 particle consisted of some minicrystal , but after the initial stage the sio2 particle was formed by some soluble aggregated substance growing on the surface of the early particle 运用扫描电镜、透射电镜、激光粒度分析仪等检测手段,探讨了体系中超细二氧化硅颗粒的形成机理和过程,指出超细二氧化硅粒子前期是由体系中的微晶核组成,中后期则由体系中的可溶性缩合物在其表面生长而成。
