气孔的

So it must be careful when paleo-atmospheric CO〓 concentration was reconstructed from stomatal indexes of fossil leaves.

因此，利用化石叶片气孔参数的变化来恢复古大气CO〓浓度的变化须谨慎对待。

Potato transpiration rate, stomatic diffusive resistance, leaf chamber temperature and leaf temperature were all affected by drip irrigation frequencies to some extent.

马铃薯的蒸腾速率、气孔阻力、叶室温度、叶温均受到了滴灌灌水频率的一定影响。

The field acid rain spray system was adopted to study the effects of simulant acid rain on leaf injury and chlorophyll content, photosynthesis, permeability of cell membrane, stomatic impedance, and transpiration intensity of 11 crops.

采用田间酸雨喷淋系统在南京中山植物园研究了模拟酸雨对11种农作物的叶片可见伤害和叶绿素含量、光合作用、细胞膜透性、气孔阻抗、蒸腾强度的影响。

According to optimized formula,the quality of product is high with light color,elasticity,many well-proportioned pores in slice,tastiness and delic...

按照该配方生产出的鱼糕色泽鲜亮，有弹性，切面致密有均匀较小的气孔存在。爽口、鲜美、滑嫩，细腻易咀嚼。

The results show that a sound bonded interface is obtained without sheet inclusion, pore and unbinding. The microstructure consists of bulk α-Mg phase and needle compound in the weld metal, element Al diffuses along the grain boundary of the substrate into the welding line. A little Y diffuses into the base metal. A little Mn and Cu segregate and element Ni distributes homogeneously and no segregation appears in weld area.

结果表明：界面接合良好，未观察到片状夹杂物、气孔及未焊合等缺陷；焊缝区由块状α-Mg相和针状化合物组成，基体中的Al元素通过晶界扩散偏聚到焊缝中，微量Y元素扩散到基体中，有少量的Mn和Cu元素发生偏聚，Ni元素分布均匀，没有发生偏聚现象。

A lot of study showed that: the main reason for this was that plantlets grew in the sealed vessel and depend on sugar in the medium, which resulted to poor development of leaf, unflexible open-close of stomata and low chlorophyll content. So, plantlets lose photosynthetic ability.

国内外许多研究报道认为，组培苗生长不够健壮主要原因是组培小植株长期在密闭环境中生长，靠培养基中的糖进行异养，而导致叶片表层结构发育差，气孔开闭功能差，叶片小，叶绿素含量低，最终使小植株丧失了光合作用的能力。

Blackheads are not caused by dirt but by the discoloring effect of air on the fatty material in the clogged pore.

blackheads不褪色造成的影响，但污垢的脂肪物质在空气孔阻塞。

These results suggest that the decrease of Pn under sub-high temperature was maybe mainly induced by non-stoma limiting factors,and the earlier the plants were treated by sub-high temperature after they effloresced,the worse the photosynthesis the plants were.

认为番茄叶片Pn的降低主要是由非气孔限制因素引起的。

The being used plating technologies are not satisfied because that pinholes and cracks appear in electrodeposits due to hydrogen absorption.

但现在的电沉积工艺因吸氢严重致使镀层含有大量的气孔和裂纹，不能满足要求。

With the porous hulls of other grains, steam easily passes through, so no significant pressure is produced.

其他的谷物的外壳是有气孔，水蒸气非常容易穿过，不会产生压力。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
