如β=〓与β=〓相比较（β角单位为弧度，其定义详见正文），前者与后者对应的气室最大压力之比可达65%，而对应的自动机动能之比可达60%；导气管内径对气室内气体压力冲量和自动机动能的影响存在极值点，且该极值点随导气孔的增大而有规律的增大；导气管长度对气室最大压力、压力冲量和自动机动能的影响呈单调递减规律，且自动机动量与管道长度之间近似符合一直线关系。

These microscopic characteristics of pollen grain and stomata could be used as the evidence to identify diaploid spieces and hexaploid, octoploid spieces whose chromosome ploidies are hugely different.

结论］用花粉粒和气孔的一些微观特征作为鉴别二倍体和六倍体、八倍体等染色体组倍数相差较大的物种有一定的依据。

The results showed that the diurnal changes of photosynthesis of S. chinensis in tile overstory took on "double-peak" curve with remarkable midday depression. The midday depression was mainly due to non-stomata1 limitations. On the contrary, the diurnal changes of photosynthesis of S. chinensis in the understory took on "one-peak" curve with low Pn. The maximal Pn was only half of that of S. chinensis in the overstory. The correlation analysis showed that the limiting factor for this low Pn might be light intensity (p=0.001). Compared with its accompanying plants, S. chinensis was in a disadvantaged status in the community with low photosynthetic capacity, water use efficiency, and the ratio of photosynthetic rate to respiration rate.

结果表明：夏蜡梅冠层的光合速率日进程呈"双峰"曲线，有明显的"午休"现象，经分析其"午休"的原因主要是由非气孔因素引起的；林下夏蜡梅则表现为"单峰"曲线，净光合速率较低，最大净光合速率不及冠层的1/2，相关分析结果表明其最重要的影响因子是光合有效辐射(p=0.001)；与其它伴生植物相比，夏蜡梅的日均光合速率、最大光合速率、水分利用效率和光合速率／呼吸速率都明显偏低，在群落竞争中处于不利地位。

Globular, non-dendritic microstructure is quickly and efficiently formed and enables the partially solidified slurry to fill the die quiescently with minimal porosity.

球状、非树状的显微结构快速有效地形成并使部分凝固的、有最少气孔的铝浆平稳地压射到模具中。

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。

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。

Unvented and indirectly vented goggles when used properly, can help provide eye protection from splashes, sprays and droplets.

在正确使用的情况下，气密型眼罩，或设计有非直接通气孔的眼罩，能帮助降低眼睛对飞溅物、喷溅物和液滴的暴露。

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。

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