气孔

Cyclophos phamide printer power is not enough, print, nbspvacuum box sealless and air hole plug or is not set properly on the evacuation time attributed the exhaust air pressure inside the bad; not enough film drop and PS version photographicsensitive coatings cannot be tight.

晒版机真空泵功率不敷、晒版框不密封、气孔畅通或抽气工夫撤销不妥等来因变成抽气不良；框边气压回升不敷，不顶片和PS版的感平涂层不不妨密接。

Leaves needlelike, slender or stout, straight or twisted, triangular, flabellate-triangular, or semiorbicular in cross section, stomatal lines several, on 1, 2, or all surfaces, vascular bundles 1 or 2, resin canals 2-10 or more, marginal or median, rarely internal, base enclosed by persistent or deciduous, membranous sheath. Pollen cones usually borne in spikelike clusters at base of 1st-year branchlets, sessile, cylindric or ovoid; pollen 2-saccate.

叶针状，纤细的或粗壮，直的或扭曲，三角形，扇形三角形，或半圆形在横断面上，气孔线数个，在1，2上，或全部表面，在第1 年的小枝，无梗，圆筒状的或卵球形的穗状的簇生在基部里的雄球花通常着生；花粉2囊。

It was found the flow velocity gradients around the gas-tunnel was high enough to cause air mixture and sand-core washing-out, the casting should be with good sinkhead and gas-venting ability.

对铸造过程充型模拟的计算结果可知，在气道附近区域，流体流动的速度梯度很大，容易出现卷气、冲刷砂芯等现象，因此，在这些区域出现气孔、针孔和缩孔、砂孔等缺陷的可能性很大，为此，必须保证铸件凝固补缩良好、排气通畅。

The results showed that the treatment with spermidine promoted the activities greatly of SOD、POD and photosynthetic intensity but reduced the stomatal resistance to some extent ...

结果表明，亚精胺处理大大提高玉米幼苗中SOD、POD的活性以及光合强度，适当减小气孔阻力，故亚精胺可以提高玉米幼苗的抗旱性。

A very variable species: specimens occur with spinescent or obtuse leaf apices and with or without white stomatal bands on the adaxial leaf surface.

一非常易变的种：标本发生具具刺或钝叶尖并且有或没有白色气孔带在叶正面上。

Leaves glossy deep green adaxially, narrowly linear-lanceolate, straight or slightly falcate, 0.8-6.5(-7) cm × 1.5-5 mm, midvein green abaxially, 0.3-1.2 mm wide, flat with median longitudinal keel throughout, stomatal bands present on both surfaces, bands on adaxial surface 0.5-1.5 mm wide, of 7-28 rows of stomatal, white powdery or not, bands on abaxial surface 1.2-2.8 mm apart, 0.3-0.8(-1) mm from leaf margin, not or rarely white powdery, base decurrent, margin denticulate, sometimes indistinctly so, especially on old trees, with 18-55(-90) teeth per side, apex usually symmetric and spinescent, spine 0.3-2 mm. Pollen cone fascicles terminal, 1-3(-5) together, broadly obovoid, each of 8-20 cones, occasionally a few also around base of seed cone; peduncle 2-4 mm; cones narrowly oblong-conical.

正面的叶有光泽的深绿色，披针形狭线形，直的或稍镰刀形， 0.8-6.5(-7)厘米×1.5-5毫米，中脉绿色背面，全部的0.3-1.2毫米宽，平的具中间的纵向的脊，气孔带宿存在两面，在正面0.5-1.5毫米宽上条纹状，7-28排stomatal的，与否白色粉状，相隔1.2-2.8毫米的条纹状的在背面，从叶缘的0.3-0.8(-1)毫米，白色敷粉的或很少的不，基部下延，边缘具小齿，有时不清楚如此，特别是在古树上，具18-55(-90)齿每边，先端通常对称和具刺，刺0.3个-2毫米雄球花束簇终端，花序梗2-4毫米；圆锥形孢子叶球狭长圆形。

The results show that the zirconium sol has good spinnability when n: n= 1:3, reaction time is 6h and aging temperature is 15℃. The ZrO_2precursor fibers are made from hydrous zirconia chelated by acetylacetone. The sintercd fibers arecomposed of metastable tetragonal phase and sized about 15μm in diameter. Moreover, there aremany pores inside the fibers, but no cracks.4. ZrO_2/PVP hybrid fibers were prepared by blending the spinnable zirconium sol and 10 wt%PVP solution.

结果表明，当n(ZrOCl_2·8H_2O)：n(H_2O_2)=1：3，反应时间6h，陈化温度15℃时可得纺丝性能良好的锆溶胶，ZrO_2前驱体连续纤维的组成主要为经乙酰丙酮配位的ZrO_2水合物，热处理后的ZrO_2纤维的相结构为亚稳四方相，纤维的直径为15μm左右，纤维中存在大量的纳米级气孔，但无明显裂纹。4。

We can see copper-bearing asphalt amygdaloidales in the basalt lava and stockwork of native copper in the carbon-rich tuff. There area so much carbon in the ores that people only can see the native copper aggregate after splitting and polishing the ores.

最近，在该熔岩层上下的凝灰岩中鉴别出难识别矿化类型，即与沥青和有机质碳紧密伴生的富铜矿石，甚至在气孔状熔岩中发现呈杏仁体含铜沥青，因而可能构成大规模矿化。

The opening of stomata seems to be an energy-consuming process.

气孔的开放似乎是一个能量消耗的过程。

So it is necessary to regulate the opening and closing of stomata in order to save water and improve plant drought resistance.

因此有必要对气孔的开关进行调控。

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！
