By adopting appropriate transformation , this paper transform the heat conduction equation with internal heat source into a non - source heat conduction equation , and then solve the problem successfully by the method of separation of variables 其关键方法是:通过将电场量引入温度场方程,作适当变换,把含内热源的热传导方程转化为不含内热源的热传导方程,然后采用分离变量法进行求解。
It is similar to saturn and jupiter in many respects , like the atmosphere composition , the internal heating mechanism , the presence of magnetic field , existence of many satellites and a ring system , etc . the streaks in the following photo are background stars not related to the ring 它和土星木星在很多方面十分相似,例如大气成分内部热力转化机制行星磁场及拥有光环和大量卫星等等。下图中白色的光迹是背景星和天王星的环无关。
Modern pharmacology study proves that pearl has the functions of relieving uneasiness of body and mind , cultivating moral character , reducing internal heat , refreshing , strengthen body with supplying calcium , clearing and protecting eyes , smoothing skin and moisture , rebirthing skin , dispelling speckles and spot , anti - crinkles and whitening , etc 现代药理学研究证明:珍珠对人体具有镇心安神、静气养性、消炎清火、壮阳提神、补钙键骨、护眼明目、保水润肤、老皮再生、除痘祛斑、抗皱美白等作用。
Cylinder dryer is a dind of rotatin continuous drying equipment with internal heating conducting - style , certain thickness of materials film theres to the lower trough of materials under the rotating cylinder . heat is transferred to the internal wall of the cylinder through pipes and misfired ahain to the external wall and to materials film , to evaporate and damnify moisture in materials film so as to dry materials 滚筒干燥机是一种内加热传导型转动连续干燥设备。旋转的滚筒通过其下部料槽,粘附着一厚度的料膜。热量通过管道辅送至滚筒内壁,传导到滚筒外壁,再传导给料膜,使料膜中的湿度得到蒸发、脱湿、使含湿份的物料得到干燥。
Value evaluates a specification to be evaluated through 5 respects value , what show in the graph is by central emanative 5 groups of coordinate , the extraction of coordinate center is worth for 0 , the numeric value that presses divide into equal parts is outward outside disperse the internal heat with sudorifics , highest value is 100 价值评估说明通过五个方面来评估个股的价值,图中显示的是由中心发散的五组坐标,坐标中心的取值为0 ,按等分的数值值向外外发散,最高值为100 。
Internal heat is the heat source from the interior of celestial objects, such as planets, brown dwarfs, and stars, caused by gravity, nuclear fission and decaying radioactive materials. The amount of internal heating depends on mass; the more massive the object, the more internal heat it has.
