气孔

Epidermal hairs and stromatal apparatus of Morinda L.

羊角藤属叶表皮毛和气孔器的电镜扫描观察。

The grain granularity distribution of system is changed when the amounts added is above 10%, this results in the imperfect and noncontinuous structure, meanwhile, new structure has not formed, the porosity of sample increases, intensity decreases.

加入量超过10％时，由于改变了体系的颗粒级配，造成原结构骨架不完整，不连续，而新的结构骨架还未形成，试样气孔增多，强度降低。

The Vihurnum opulus L's controlling factor of photosynthetic rate was non-stomatal limitation.

2欧洲荚蒾光合速率控制因子为非气孔限制。

As introduced by relative information, for foreign plants have not solved the joints between over-voltage crosslinked polythene cables so far, the second method should ensure that the crosslinked polythene layer of excessive thickness filled during the later pressed heating sulfuration process has nohuge air hole is produced and left if the thickness extruded at one time is overlarge to 15～30mm during the process of plastic extruding XLPE crosslinked polythene to recover insulation.

第二种方法，据有关资料介绍，由于国外厂家还未解决超高压交联聚乙烯电力电缆的中间接头，在绝缘恢复挤塑XLPE交联聚乙烯的工艺过程中，一次挤出的厚度如果过大，达的时候，要保证填充的过大厚度交联聚乙烯层在后期加压加热硫化工艺中，不产生留存有大的气孔。

Leaves spirally arranged, radially spreading, or pectinately arranged in lateral sets, linear, straight or curved, flattened, grooved adaxially, stomatal bands 2, abaxial, vascular bundle 1, resin canals 2(-10 outside China), marginal or median, rarely submedian, base twisted. Pollen cones borne in leaf axils of previous year's branchlets, pendulous, narrowly ellipsoid or oblong when young, finally cylindric; pollen 2-saccate.

叶螺旋状排列，光线传播，或pectinately排列在方面侧确定，线形，直或弯曲，扁平，正面具槽，气孔带2，背面，维管束1，雄球花生于第二年小枝的叶腋，下垂，或长圆形的狭椭圆形幼时，最后圆筒状；花粉2囊。

1 Water stored in soils. 2 One of the most important elements involved in pedological processes and plant growth. There are three basic form-: water adhering in thin films by molecular attraction to the surface of soil particles and not available for plants is termed hygroscopic water. b Water forming thicker films and occupying the smaller pore spaces is termed capillary water.

储藏在土壤中的水分，2）在土壤过程和植物生长中最重要的元素之一，有三种基本形态-：（s：a 藉分子间引力以薄膜形式附著在土壤颗粒表面的水分，不能被植物利用，称为吸湿性水， b形成厚的水膜填充在较小土壤气孔中，称为毛细管水。

Results Cuticular papillates,glandular hairs,peltate scales,and non-glandular hairs presented on the leaf epidermis of C.paliurus.Anomocytic stomata were confined to the lower epidermis.Large cluster crystals existed in the uppermost layer of palisade cells.Midrib included one closed vascular system and one additional vascular strand.Secondary veins are semicraspedodromous and form marginal loops,tertiary veins are percurrent,quaternary veins form orthogonal or polygonal areoles filled up by branched and freely ended veinlets.

结果青钱柳叶表皮有许多小乳突，腺毛，盾状鳞片和非腺毛表皮毛；气孔器不规则型，仅分布于下表面；靠近表皮的叶肉组织中有规律地分布含簇晶的细胞；主脉中维管组织环状，封闭，具有一个副维管束；二级脉在叶缘内分支，相互连接形成脉环，三级脉及顶型，脉间区内充满分支的自由结束的小细脉。

The melting point of the pure periclase magnesia is 2,800℃, some impurities may reduce the melting point of the magnesia , borides influence is extremely remarkable.

纯净的方镁石型氧化镁的熔点为2800℃，一些杂质可使氧化镁的熔点降低，其中硼化物的影响极为显著，即使是少量的硼化物(0.01%-0.02%)的存在就将导致氧化镁的抗蠕变性能明显降低，而B2O3在高温时的气化能够造成氧化镁材料的气孔率增大，严重影响其高温强度，故镁砂降硼是非常重要的。

The results show that higher zircon addition resists the densification of fused magnesia zirconia materials,and the zircon addition influences the crystalline size of periclase,pore size and the pore structure significantly.

结果表明，配料中锆英砂含量的增加使熔浆的粘度上升，合成料难以致密化。锆英砂配入量对ZrO2晶形及晶粒尺寸影响不大，但明显影响方镁石的晶形、晶粒尺寸以及气孔的形状和尺寸。

After fired at 1600℃, with the increase of zircon addition the bulk density of the samples increases while apparent porosity decreases. When zircon addition is 4%, the strength is the best, and the photomicrograph of the sample exhibits a densely packed microstructure, with larger and better developed grains of periclase and spinel. Meanwhile, the direct bonding of solid phases is reinforced.

在1600℃热处理下，随着w(ZrSiO4)的增加，试样的体积密度增大，显气孔率变小，试样力学强度在w(ZrSiO4)为4%时达到最大值。w(ZrSiO4)为4%的试样整体显微结构致密，固相直接结合程度提高；并且方镁石和尖晶石晶粒的晶粒尺寸粗大，晶粒发育比较完整。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
