而静态生命表分析显示锐齿栎种群的存活曲线为DeeveyⅡ型，死亡率曲线有两个高峰；

The result revealed that the population age structure exhibited the characteristics of stable type , the curve of survival generally trended to the Deevey ⅱ, and there were two peaks of mortality .

让我介绍一下我的新兄弟：锐齿和利爪！

Yells when absorbing Lynx Spirit : Let me introduce to you my new bruddahs : fang and claw !

文章以小陇山锐齿栎群落为例，分析了不同发育阶段土壤的特征。

Taking sharp tooth oak community in Xiaolongshan as an example , The research analysed the soil characteristic at different development stage .

坡向对锐齿槲栎种群的更新有重要影响，光照好的东南坡上的更新情况明显比光照较少的西北坡好。

Influence of the slopes with different directions on population regeneration was also studied , and it showed that the slope direction was one important factor for regeneration .

无糜烂组锐齿型、破碎型、三角延伸型、舌样延伸型齿状线多于正常对照组，差异有统计学意义（P<0.05）。

There were more serration , fractured , triangular extension , and tongue-like extension Z-lines in the non-erosive group than in the control group . The difference was significant ( P < 0.05 ) .

锐齿槲栎的非结构性碳水化合物含量随着海拔升高而降低，铁橡树中在中、高海拔却略有升高，显示出两种植物碳资源分配和利用策略的不同。

Non-structural carbohydrate content decreased with increasing altitude in Qa , yet which escalated at high and medium altitude for Qs implying there were different carbon resource allocation and use strategies in two kinds of plant .

通过固定标准木、定期采样和化学测定，分析了秦岭锐齿栎林叶内营养元素含量的径阶、冠向、冠层、海拔和生长季节变化规律。

The foliage nutrient contents of sharptooth oak stands in Qinling Mt. with different diameter classes , crown directions , crown layers , elevations and seasonal variation have been studied in this paper by fixed sampling trees , regular samplings and chemical analysis .

结果表明：（1）随着海拔的升高，锐齿槲栎叶形态特征在海拔间相对比较恒定，仅低海拔的干重较中高海拔稍大而叶形指数又稍小。

The main results are showed as follow : ( 1 ) The leaf shape and size was relatively constant in Qa along the altitudinal , only the dry weight was higher and the leaf shape index was smaller in low altitude than that in medium altitude gradient .
