Heat transfer will worsen if structure parameters of the spring inserts are not fit. The paper think that the mechanism of heat transfer enhances of the spring inserts is the laminar flow lining is thinner because of librating of the spring inserts, accordingly the part of convection is enhanced. But the part of boil is not influenced.

Summing up these results, we think that the Yinmawanshan batholith came from the mixing, the fractional crystallization and the crust contamination of the enriched lithospheric mantle and the low crust magma.3、the time relationship between the Yinmawanshan batholith' formation and the tectonic extension The field observation and petrology have clearly showed that the Yinmawanshan batholith intruded in the forming period of the Liaonan metamorphic core complex, so this provided direct geological evidence to the viewpoint that the early Cretaceous magamatism of the eastern China developed in the extensionally tectonic setting.

还有一个证据来自对A型花岗岩的研究。A型花岗岩的年代学研究结果显示在东北的大兴安岭地区、张广才岭地区、本文研究区的辽东半岛，几乎所有的上述A型花岗岩都是在120-130 Ma期间形成的，与本文研究的饮马湾山I型花岗岩同时。地球化学资料还显示，这些花岗岩基本具有A1型非造山花岗岩的特点，充分反映了我国东部早白垩世的地质演化与伸展体制有关。根据上述资料我们推测，辽东半岛南部饮马湾山岩体形成时的我国东部由于受岩石圈减薄作用影响而使全区处于伸展构造体制。
