However, it is not known how orthodontic force influences the function of cementoblast and what is the relationship between the function change of cementoblast with root resorption. So we studied the effect of mechanical stimuli on root resoption by examining the expression OPG and RANKL and exploring the related signal transduction pathway in cementoblast. Methods: Cementoblasts OCCM30 were cultured in DMEM with 10% FBS for 48 hours and starved in DMEM with no FBS for 24 hours, then subjected to mechanical strain by four-point bending system with tension and compression stress at 2000μstrain at 0.5Hz frequency. The flow cytometry was used to examine the cell cycle and proliferation activity after 3h, 6h, 12h, 24h loading respectively. OPG and RANKL mRNA were analysed with real time quantitive RT-PCR after the same loading period as FCM.

本课题利用四点弯曲力学加载系统，采用流式细胞术、实时荧光定量PCR、Western免疫印迹等方法，研究体外培养的成牙骨质细胞株OCCM-30在不同力学环境中增殖活性的变化，以及其表达骨保护素和破骨细胞分化因子的mRNA的变化，探讨应力刺激对成牙骨质细胞表达破骨细胞分化调控蛋白的影响，并通过对应力刺激下成牙骨质细胞分裂原活化蛋白激酶家族中的ERK1/2、P38MAPK活性的变化及其与OPG、RANKL基因表达变化关系的研究，对力学刺激调节破骨细胞分化调控蛋白的相关上游信号转导通路进行初步探讨。

Accuracy of determination of deacetylation degree of chitosan by two abrupt change conductometric titration was studied, and effects of chitosan solution concentration, viscosity and deacetylation degree on the result of equivalence point were also investigated.

结果表明：壳聚糖样品质量浓度控制在2～6g/L，利用双突跃电位滴定法可以测定壳聚糖的脱乙酰度，不同样品脱乙酰度测定结果RSD小于0.61%(n=3)，该方法具有较高地准确性，可以用于壳聚糖生产和加工过程中的质量控制与检测

Using the spatial point-pattern analysis of Ripley's function, the result indicated that Halostachys caspica population of Ass.halocnemum strobilaceum-H.caspica community on the northwest edge of Junggar Basin shown congregative pattern in 0~50m scale.But Halocnemum strobilaceum population shown congregative pattern in the same scale or the less scale. And there was a positive, no relation and negative relation change series in space between Halostachys caspica and Halocnemum strobilaceum.

采用空间点格局分析方法Ripley，s K函数分析表明，准噶尔盆地西北缘盐穗木-盐节木群落的盐穗木种群在所研究的尺度(0～50m)上呈聚集分布，盐节木种群呈现聚集分布的尺度等于或小于盐穗木种群；盐穗木与盐节木的种间关系在空间上呈正相关、不相关和负相关变化序列。

By dilatometric change referencing microscopic test and hardness measurement, the critical point at Ac1, Ac3 and Ms of 27CrMo27S steel was determined in Gleeble-3800 thermal mechanical simulator, By measuring the different expanding curves of CCT in different cooling rate, CCT diagram was obtained.

利用膨胀法结合金相-硬度法，在Gleeble-3800热模拟机上测定了27CrMo27S钢的临界点Ac1、Ac3以及Ms；测定了该钢在不同冷却速度下连续冷却时的膨胀曲线，获得了连续冷却转变曲线；研究了冷却速度对该钢组织及硬度的影响。

By dilatometric change and microscopic test, the critical point at Ac1、Ar1、Ac3 and Ar3 of ML40Cr steel was detemined in Gleeble-3800 the thermal-mechanical simulator. The continuous cooling transformation diagram of ML40Cr steel was obtained by measuring the expanding curves of different cooling rates. The mechanical property and transformation of austenite were analyzed. The proper range of control cooling rate about ML40Cr cold heading steel was found. All those provide the reference for productive practice to develop cold heading steel.

在Gleeble-380热模拟试验机上采用热膨胀法－金相法测定了ML40Cr钢的临界点Ac1、Ar1、Ac3、Ar3，同时测定了在不同冷却速度下过冷奥氏体连续冷却时的膨胀曲线，获得了该钢的连续冷却转变曲线；研究了ML40Cr连续转变冷却过程中奥氏体转变过程和转变产物的组织和性能，初步确定了ML40Cr盘条的控制冷却范围，为冷镦钢ML40Cr盘条的开发提供了参考依据。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
