气孔的

The primary resistances for CO2 diffusion are thought to be at the stomata and at photosynthesizing cells via a combination resulting from resistances of aqueous solution as well as the plasma membrane and both outer and inner chloroplast membranes.

CO2扩散速率的主要限制因素不仅与气孔和光合细胞中它的水溶性有关，还与质膜和叶绿体内外膜有关。

He and his team have identified proteins that control the tightening of a plant's pores.

他和他的研究小组鉴别出了控制植物气孔紧缩的蛋白质。

The material contains a large number of pores whose sizes are about 300～500 μm.

The results showed that ABA concentration in xylem sap in the drying plants was quintupling of that in witting plants,and became duplicate with 0.12 g·cm-3 increament of soil bulk density.

生长在混合容重(一边为1.20g·cm-3，另一边为1.45g·cm-3)土壤上的植株中，ABA浓度和气孔导度与全部根系处在高容重土壤中的植株接近。

RESULTS: The surface feature of each sample showed globular granule with caky structure and air pore. The crystal structure of group A, B, C mainly showed characteristic absorption band of Ca102(PO4)6 which degraded while antimicrobial content increased. Except Ca102(PO4)6 and CaZr (PO4)2, Na6CaP2O9 also appeared in group D.

结果：4组涂层材料镜下表面形貌相似，均为球状颗粒中夹杂&饼状&结构及气孔；A、B、C组晶相主要呈现羟基磷灰石主要成分Ca102(PO4)6的特征峰，且随抗菌剂含量上升，峰值降低。D组除主要呈现Ca102(PO4)6的特征峰外，还出现CaZr(PO4)2、Na6CaP2O9等新相。

The manufactured techniques of burned Magnesite chrome bricks are the same as magnesite bricks, with low porosity, high strengty and refractoriness under load, Their slag corrosion resistance and high temperature strengty are also better than other magnesite chrome brick.

烧成镁铬砖的生产工艺与镁砖大体相仿，其主要特点为：砖的气孔率低，耐压强度、重软化温度和抗折强度均较高，抗渣性和高温强度均比其他镁铬砖好。

The voice coil is wound on an aluminum voice coil former with adequate ventilating holes to eliminate noise from internal air flow.

音圈镶嵌在一个铝制骨架上，这个铝制音圈骨架有足够的通气孔以消除内部空气流动引起的噪音。

While they bear down on the phone, Michael sneaks around and stuffs baggies into the air vents of Chrisina's car and turns up the AC full blast.

当他们向手机所在地行进时，迈克尔溜进克里斯蒂娜乘坐的车内，将袋状特塞在车内的空调气孔内，将电源开到最大。

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%.
