The wooded area reduced in the past several hundred years, the temperate zonearea country has lost the majority of forests.
森林面积减少 在过去数百年里,温带地区国家失去了大部分森林。

Under low packing density, convection is significant in shell-side flow, which is preferable for the reduction of dead zonearea and the higher utilization of contacting area.
较低的封装分率下,组件壳程对流作用明显,有利于减少死区,充分利用膜接触面积。

Based on the fluid properties in the fault zonearea, the fluid flow characteristics and pool-forming process along Lanliao fault zone in Dongpu Depression are thoroughly analyzed.
