有气孔的

Scientist: The point is that the worlds soils are a very large reservoir of carbon and two things can happen you can either manage it so they get bigger and therefore lock up carbon, or mismanage it so that pore gets smaller and in fact you release carbon and add to the CO2 in the atmosphere and it works both ways.

科学家：我们要指出的是，地球上的土壤是一个巨大的碳储存库，有两种情况会发生，一方面我们正确的利用它，增加它的容量以达到固碳减排的目的，另一方面我们的错误做法会使土壤中气孔变小，造成碳释放，增加大气中的二氧化碳含量，事实上这两种情况是同时存在的。

Tight alloying layer with undulation and without visual pocket and inclusion has been obtained by experiment.The alloying layer is metallurgically combined with the matrix.

试验结果获得了致密、无肉眼可见气孔、夹杂、熔覆表面有一定起伏的合金层，合金层与基体间完全冶金结合；熔覆合金层由单相Fe3 Al构成，覆层组织为粗大的柱状晶团，柱状晶团内包含大量极细小的板条状Fe3 Al晶粒，一些相邻的板条晶之间具有基本相同的晶体学取向。

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。

Experiment result indicates that laser power density,welding speed,pulse frequency and pulse width are the key factors of pulse laser welding and that the polishment,close touch of butt joint faces have an important effect on the air vents number in welding line and the mechanical performance of welding line.

实验结果表明：对焊面的打磨、抛光和紧密接触对防止焊缝中产生过多的气孔和提高焊缝的机械性能有重要作用；激光功率密度、焊接速度、脉冲宽度和脉冲频率四个参数是实现脉冲激光焊接的关键因素。

In addition, the way in which the ratio of CO 2 concentrations in and out of the stomata changes with light and the influence of boundary layer conductance on the ratio had also been simulated.

这与许多研究者的分析和实验是一致的［5，8，9］，所以有必要进一步研究叶片边界层阻力对气孔导度和光合速率的

Risers in a 1-2 class gliders with unsheathed line in the top floor (lines made out of the new aramide with UV protection and dynema pre-stretch of the latest generation) The lines are rigged in two floors and the attachment point are placed everfy 2 or 3 cells, therefore the number of total lines are few and the line consumption does not arrive to 300m in total.

1-2类的滑翔伞配3组带，其中顶部为裸绳。（绳的材料为：新形aramide 人造纤维之一种，UV 保护层和新一代dyneema 预拉）。伞绳被分成两层（The lines are rigged in two floors），每2至3个气孔之间有连接点。因此，伞绳的总数量很少，整个伞仅消耗300米的伞绳。

The operation conditions in these stages have influence on the flow patterns of molten metal and the air entrapment in the shot sleeve .

低速压射过程中冲头的运动分为封闭浇料口、匀加速和匀速低速三个阶段，各个阶段的工艺参数对压室内金属液的流动形态都有重要作用，进而影响铸件中气孔缺陷的产生。

The presence of small blowholes (2-4#m), caused by escaping volatiles, is evident on the rather rough surface of these chars.

这些半焦的粗糙表面明显有挥发物逃逸时造成的小气孔（2-4微米）。

Jean de marle montague and bule bell had high net photosynthetic rate P(subscript n, transpiration rate T(subscript r and stomatal conductance G(subscript s, and showed high photosynthetic and potential productivity. The two cultivars also had low light compensation point and high light saturation point, showed high capacity for using light.

品种红粉玉蝶、井岗紫霞具较高的净光合速率、蒸腾速率和气孔导度，表现出较高的光合作用能力和生产潜力；同时这2个品种又有较低的光补偿点和较高的光饱和点，表现出较强的弱光利用能力和强光利用潜力。

The results showed that net photosynthetic rate P(subscript n, transpiration rate T(subscript r, stomatal conductance G(subscript s, intracellular concentration of CO2 C(subscript i, water use efficiency of cultivars and the light saturation point in leaves of 5 cultivars were different and had obvious differences, and the light compensation point was similar. Diurnal change of net photosynthetic rate among cultivars were different, three cultivars showed twin-peaked curve with an obvious midday-depress, others showed single peak curves.

结果表明：不同品种的净光合速率P(下标 n、蒸腾速率T(下标 r、气孔导度G(下标 s、胞间CO2浓度C(下标 i、水分利用率和光饱和点之间的差异明显，各品种的光补偿点均较低；净光合速率的日变化也存在明显的品种间差异，有3个品种呈&中午降低型&的双峰曲线，2个品种呈单峰曲线。

I will endeavour to find you some assistance.

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
