The results showed that soil copper contamination did not significantly affect the leaf growth of Bermuda grass and its influence on root biomass and leaf chlorophyll content in Bermuda grass were also less than that in zoysiagrass.

结果表明：铜污染处理对狗牙根草坪的地上部分叶片生长量的影响不显著，对根系生长量和叶绿素含量的影响也明显小于结缕草；铜污染处理未引起冷季型草坪的叶绿素含量的下降，对高羊茅草坪的密度影响不显著，对叶片生长量的影响也明显小于草地早熟禾和多年生黑麦草，而草地早熟禾虽然叶片生长受到了严重的抑制，但根系生长未受到显著影响，也表现出了对土壤铜污染的一定的耐性。

Bermuda grass pollen is an important major grass pollen allergen not only in Taiwan but also in the world. The 34 kilodalton major allergen of BGP, Cyn d 1, had been well-characterized.

狗牙根禾花花粉在台湾及世界各地都是主要的禾花花粉过敏原，其中主要被研究的是34Kda的第一类主要过敏原Cyn d 1。

Two warm-season turfgrasses, including Bermuda grass and zoysiagrass, and three cool-season turfgrasses, including tall fescue, Kentucky bluegrass and perennial ryegrass were selected to study their growth responses under the simulated soil copper contamination conditions.

通过模拟土壤铜污染处理，对2种暖季型（狗牙根Cynodon dactylon、结缕草Zoysia matrella）和3种冷季型（高羊茅Festuca arundinacea、草地早熟禾Poa pratensis、多年生黑麦草Lolium perenne）草坪草种的生长指标进行了分析。

As to Write clover and Bermudagrass, theirs root system tensile strength P and root system diameter relation of D fit with index comparatively accurate, comparatively accurate with the method that the multinomial fits to the Amopha fruticosa.

对于白三叶和狗牙根，其根系抗拉强度P和根系直径之间D的关系用指数拟合较为准确，对于紫穗槐则用多项式拟合的方法较为准确。

2The density of human teeth is approximately among 1.20-1.40+103kg/m3. The density of crown is higher than that of root with significant difference.

人类牙的密度值恒定在一定范围之内，约在1.20～1.40×10~3kg／m~3之间，且牙冠密度值明显大于牙根密度值。

Each consists of a crown above the gum and one or more roots below it, embedded in the jaw.

每颗牙有一个在牙龈之上的牙冠和牙龈之下的一个或多个牙根，固定于颚中。

Teeth have two basic parts, a root to anchor the tooth to the jaw and a crown above the gum line.

牙齿有两个基本部份，牙根把牙齿锚定在下颌上，牙冠位于齿龈线以上。

［Objective］ This work is to study the relationship of mandibular third molars between the number of dental cusps and that of roots.

［目的］探讨下颌第三磨牙的牙尖数与牙根数的关系，为临床拔除阻生齿提供依据。

After transplanted in nude mouse for 8 weeks, DAC-MSCs can regenerate cementum-like structures and dentin-like structures. At the same time, we used limiting dilution assay to screen monoclonal cells from DAC-MSCs and discovered two kinds of phenotype cells: one is osteogenesis type, and the other is fibro singtype.

结果显示：牙根发育期根尖复合体来源间充质干细胞为异质性；具有显著的&胚胎性&组织特征：表现出极高的增殖活性、克隆形成能力和体外多向分化能力；在体内可以异位形成类牙骨质和类牙本质样矿化结构。

At the buccal and lingual furcations of the mandibular first and second molars, they were recorded as 1.90 ± 0.08mm and 2.90 ± 0.07mm, and 2.82 ± 1.34mm and 3.46 ± 1.03mm, respectively.

CEJ 至牙根分叉入口处的距离平均值：上颚第一大臼齿的颊面，近心面及远心面的平均值分别是3.42±l.05mm；3.55±0.97mm及3.69±0.98mm。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
