Objective. 1. There was few researchers who mentioned pericementum which has some effect of resistance to sliding when they studyed the friction of archwire-bracket.

一、研究目的： 1、鉴于目前在测定弓丝与托槽滑动阻力时，均没有考虑到牙周膜对滑动阻力的影响，因此本实验尝试建立一种新的实验模型，分别模拟牙，牙周膜，牙槽骨。

Feasibility of tricocyst test with Tetrahymena pyriformis were evaluated by serial chemicals (Cu2+, Cr2O2-4,Cd2+,MMC, CP, Colchicine). There is no significant difference between control and treated groups with negative chemical (Cu2+).

应用致突变阴性、阳性对照(Cu2+， Cr2O2-4， Cd2+，丝裂霉素MMC，环磷酰胺CP，秋水仙素Colchicine)评价四膜虫刺泡发射实验方法的可行性，并应用该方法检测稀土金属离子La3+，Ce3+， Sm3+， Y3+， Gd3+对四膜虫刺泡发射的影响效应。

A lot of organelles such as mitochondria, rough endoplasmic reticula and Golgi bodies were observed in fiber cell. Then, double karyotheca disappeared, and the organelles disintegrated. Multivesicular bodies appeared in fiber cytoplasm. With the further development of fiber, fiber wall underwent continual thickening with aging, and polylaminate structure gradually appeared. While the agglutinated nucleus, transfer vesicles, plasma membrane and plasmodesmata still presented.

研究发现，次生壁形成早期，细胞核具有双层核膜，染色质凝聚，可见大量的线粒体、粗面内质网和高尔基体等细胞器存在于纤维细胞中；随后，双层核膜消失，细胞器将逐渐解体，多泡体开始出现在纤维细胞的细胞质；随着年龄的增加，纤维细胞壁逐渐增厚，并出现多层结构现象，而运输小泡、细胞膜、胞间连丝和凝聚的染色质将持续存在。

The reasons of iron ions content overproof in grade Ⅱ desalting water system,such as variation water quality,contamination of regenerant , operation adjustment of pretreatment system and switching operation of bed were discussed.
