Heat convected , a mode of motion developed by such combustion , was constantly and increasingly conveyed from the source of calorification to the liquid contained in the vessel , being radiated through the uneven unpolished dark surface of the metal iron , in part reflected , in part absorbed , in part transmitted , gradually raising the temperature of the water from normal to boiling point , a rise in temperature expressible as the result of an expenditure of 72 thermal units needed to raise i pound of water from 50 to 212 fahrenheit 燃烧所引起的运动形式之一-热对流传热，不断地加速度地从热源体传导给容器中的液体，由那凹凸不平未经打磨的黑色铸铁面把热向周围发散出去一部分反射回来，一部分被吸收，另一部分被传导，使水的温度从常温逐渐升到沸点。这种温度的上升可作为消费结果标志如下：将一磅水从华氏五十度加热到二百十二度，需耗七十二热量单位。
The results of the investigation in forests showed that dastarcus helophoroides adults displayed a core distribution pattern , that belonged to aggegated distribution , and changed to mosaic distribution pattern in a denser population due to the exclusion behavior among the individual in host competition 摘要林间调查和研究表明，花绒坚甲成虫的分布格局为聚集分布中的核心分布型，在群体密度较大时，由于个体间具有竞争寄主的排斥行为，其分布则转变为嵌纹分布；花绒坚甲在进入新的分布区后，首先是建立大小不等的聚集群，再以聚集群体的形式向周围扩散。
