A one - dimensional simplified model on the inner surface temperature computation conversely based on the outer surface temperature measured by infrared imager was presented 摘要利用红外热像仪获得外壁温度，在简化的一维模型下反推内壁温度。
But the shape and size of pollen , length of p and e , width of net lines , size of net aperture , net porosity among different materials were different 而花粉的形状大小、极轴长和赤道轴长、外壁纹饰中的网脊粗细、网孔大小、孔频等随材料不同而异。
It is given that quantitative diagnosis to estimation errors of internal temperature of a hot wire embedded at the center of a cylinder - shaped heat equipment 摘要对采用红外监测反推法，由加热圆柱外壁温度，确定圆柱体内壁温度的误差进行了量化分析。
It consists of an air - filled protuberance on each side of the pollen grain developed by the separation of the exine layers , giving the pollen a characteristic winged appearance 它是花粉粒外壁向外扩展而形成的囊状结构，在花粉粒两侧呈翅状，其内充满空气。
By solving an inverse heat conduction problem , one method is given about to compute wall thickness of cylinder - shaped equipment based on the outer surface tempereture 摘要利用红外测温技术，结合导热反问题求解，给出了一种根据圆筒外壁温度计算筒壁厚的方法。
Experimental results show the system performance is greatly improved by the above mentioned methods and the fine defects in the tube ' s outer wall can be detected reliably 实验结果表明，采用上述方法后系统性能得到很大提高，可以有效检测出管道外壁的细微缺陷。
In 420t / h boiler inspecting , the collecting - steam box of reheater and correlative pipelines are detected to appear diffuse crack , which has expansive trend 在对420t h锅炉的规范检查当中发现，再热器集汽箱管座及其附属管道外壁出现由内而外发散的放射状裂纹，并且有不断扩大的趋势。
( 3 ) the pollen morphology of 19 species was investigated under sem . the results show that the morphological characteristics and exine ornamentation are not similar among species and sections （ 3 ）对该属19种植物花粉形态学观察发现，花粉形态和外壁纹饰在组间和种间存在着一定差异。
Through verifying , there exist strong bonding force oxide attached on inside and outside wall of low temperature superheater tubes , and ashes are deposited between tubes , which result in producing thermal deviation 经检验，低温过热器管内、外壁附着结合力较强的氧化物，管间积灰，导致热偏差产生。
Model w still may use disassembled u type heating pipe . when maintenance , it can be removed out to the still . so it is very convenievt to clean the outer wall of heating pipe and the inner wall of still W型之蒸馏新釜采用可拆式u型力口热管，在检修时可将u型加热管移出釜外，便于对加热管外壁及蒸釜内壁进行清洗。
