Although still a matter of discussion , most researchers feel that in order to breathe , a dolphin or whale must be conscious and alert to recognize that its blowhole is at the surface 尽管有许多问题需要讨论，但大多数研究人员觉得为了呼吸，海豚或鲸鱼必须对确认它的呼吸孔在水面之上保持清醒和警惕。
Uniform micro - structure , compacted grain : melting iron is solidified by heavy spin force at right temperature , which effectively avoid the failures like blowhole , slag enclosure , pinholes and etc 组织均匀，晶粒致密：温度精确的合金溶液在上百倍的离心重力作用下凝固成型，得到致密的组织；并有效克服了气孔、夹渣、疏松等缺陷。
Abstract : the reasons of blowholes and cracks in valve surfacing are analyzed based on the measurement of residual stress and observation of fracture microstructure . then the improving plan of quality for valve surfacing is put forward 文摘:通过测定阀门经加工后的残余应力、观察裂纹断口微观组织等，分析了阀门产生气孔和裂纹的原因，并提出改进阀门质量的实施方案。
In the rotor design , it makes a detailed calculation for all the geometry feature parameters including geometry dimensions , contact line length , blowhole area and flow cross - section area and the thermodynamic feature parameters such as cooling capacity , shaft power and so on 在转子设计方面，对全部几何特性参数，包括几何尺寸、接触线长度、泄漏三角形面积和面积利用系数等以及包括制冷量、轴功率等冷水机组热力特性参数进行了详细计算。
Here ' s one possible sample pitch for the get - kids - into - birds campaign : now , i admit to almost complete ignorance about pok mon characters , which i would imagine do incredible things , like shoot fire out of their blowholes or eat rocks or design a high - mileage , low - emission suv or other magical things 以下例子或可用来进行让儿童迷上鸟儿大作战：好吧，我承认我对神奇宝贝的各种变身几乎一无所知，如果要我想像，我恐怕只能胡言乱语一番，像是它们会从鼻孔喷火、吃石头，或设计出里程数高、排气量低的运动休旅车或其他神奇之举。
New becomes the hole material as the ceramic cement blowholegrinding wheel , the - fine naphthalene compares with traditional chengkongji , has the blowhole to be even , does not have merit and so onpollution , odorlessness , easy to operate , price small advantage , alsomay wilfully adjust to the grinding wheel blowhole size 作为蜂窝陶瓷制品和陶瓷结合剂气孔砂轮的新型成孔材料，与传统的成孔剂?精萘相比，具有气孔均匀，无污染、无气味、使用方便、价格便宜等优点，且对砂轮气孔大小可任意调整。
