root face

Results show that root biomass, root volume, root length and root diameter of rice and barnyardgrass all increased significantly under FACE condition with NN ( normal nitrogen) supply, the response of rice to CO_2 was higher than that of barnyardgrass.

结果表明，常N水平下高浓度CO2显著增加水稻和稗草的根干重、根体积、根总长和根直径，水稻对CO2浓度升高的响应强于稗草；

根面龋的治疗体会

Elevated CO_2 also decreased remarkably the number of root hair and per-unit dry root weight of rice and barnyardgrass, which might be one of morphological reasons why root activity decreased under FACE condition.

高浓度CO2显著降低水稻和稗草单位根重根毛数，这可能是CO2浓度升高条件下根系活力显著降低的形态学原因之一。

The equation inferential reasoning provides the theory basis for the awl tooth transition surface, the tooth root face, cut the equation of a curve and the geometry restraint equation inferential reasoning, they are essential to formed the overall awl tooth full-scale mockup.

该方程的推导为锥齿过渡面、齿根面、切曲线方程和几何约束方程的推导提供了理论依据，它们对形成整体锥齿实体模型是不可缺少的。

Conclusion: Distalizing molars with face bow can lead to mild root resorption.

结论：口外弓推磨牙远移会造成牙根吸收，但吸收量较微小，在临床可以接受的范围内。
