The difference in stomata characters between tissue-cultured jujube tree andin field is reported in this paper.

Oxygen and carbon dioxide also pass through the stomata.

氧气和二氧化碳也会经由气孔出入.

Therefore stomata are not required in water plant.

(不是因有气孔就会使植物窒息而死).

Water exits plants through their stomata. Stomata are located on the undersides of plant leaves.

水分透过位于植物叶子下侧的气孔散发出去.

That moves out from the stomata is oxygen and water vapour.

而走出气孔的气体是氧气和水蒸气.

When relative soil water is below 75 %, the cause of rate drop is non-stomatal limitation.

当土壤相对含水量低于75%, 光合非气孔限制因素开始出现.

The stoma and guard cells are collectively called the stomatal apparatus.

临近保卫细胞处常存在变形了的表皮细胞,被称为副卫细胞.

Stomatal movement is important for plants to exchange gas with environment.

气孔运动调节植物与环境之间气体和水分的交换.

Stomatal density may become lower while water-use efficiency ( WUE ) increases with ( CO 2 ) increasing.

表现在 光合速率 提高,呼吸作用受抑制,气孔密度减小,水分利用效率增加.

However, there are few studies on the regulation of water transport in stomatal movement.

然而有关水分运输调节气孔运动的研究相对较少.

In a scanning microscope also shows that, stomatal particle size distribution is not uniform corrosion.

在扫描显微镜还表明, 气孔颗粒分布很不均匀的阴极.

When relative soil water is below 75 % , the cause of photosynthesis rate drop is non-stomatal limitation.

为试验材料,研究了不同土壤水分下叶片的生理特性以及引起光合下降的 非 气孔限制因子动态特征.

Stomatal dispersed shrinkage, shrinkage cavity, sonim and slag inclusion belong to this kind of defect.

属于这种类型的缺陷有气孔、缩松 、 缩孔 、 夹砂、夹渣等.

Under the skin stomatal more, to defend the cell Depression, Changcheng oval or spindle.

下表皮气孔器较多, 保卫细胞凹陷, 常呈卵形或纺锤形.

The research of tooth regeneration a front topic in current stomatology medical domain.

牙再生的研究属于当前口腔医学领域中的前沿课题.

Objective Discuss the application of vibration and noise test technology in the oral stomatology.

目的探讨振动噪声测试技术在口腔医学中的应用.

Professor and the deputy director in the Department of Prosthodontic, Stomatology, Peking University.

赵奇副教授----北京大学口腔医学院口腔内科主任 、 主任医师.

Dentin hypersensitivity is a common oral complaint with high prevalence in stomatology whose pathogenesis is complicated.

牙本质敏感是口腔常见病、多发病,其发病机制复杂,治疗方法多样.

Objectives To prevent and control hospital infection in department of stomatology, guarantee medical quality and safety.

目的有效预防和控制口腔科医院感染, 保障医疗质量和医疗安全.

My tooth does not feel well . I'll have an examination in the department of stomatology.

我的牙齿坏了, 要去口腔科做检查!
