查询词典 cold zone

Results show that during the snowstorm disaster, under the large scale background with "trough in south and ridge in north", strong cold air caused by prevailing northerly wind in northern Asia wedged into low level atmosphere over Southeast China and formed a "clod cushion". At the same time, warm-wet air was also transported to Southeast China by southerly wind. The vertical shear of winds from cold to warm airflows produced strong upward motion and then, the warm-wet air over the cold air wedge was driven to rise. Finally, the structure of "warm cover" and "cold cushion", as well as corresponding vertical circulation over the converging frontal zone came into being.

通过分析冷态煤粉浓度的分布及煤粉高浓度区域面积的大小，得到：中心管扩角越小，二次风混入越晚，冷态高煤粉浓度区域面积越大；一次风率为0.2、一次风速为15 m/s、直流二次风速为25 m/s时冷态高煤粉浓度区域面积较大，有利于降低NOx的生成；内二次风旋流开度减小较外二次风旋流开度减小对冷态高煤粉浓度区域面积的影响大；内旋流强度为1.35、外旋流强度为1.56为最佳的试验工况。

To investigate the response of plant growth and antioxidant system to changes of root temperatures, roots of six cucurbit plants were exposed to three different root-zone temperatures: low (14℃), middle (24℃) and high (34℃), while aerial parts of plants were maintained at the same natural ambient temperatures (23-33℃). The six cucurbit plant species could be classified into three groups with figleaf gourd and turban squash being I group (heat-sensitive but cold-tolerant), cucumber and melon being II group (heat- and cold-sensitive) and bitter melon and wax gourd being III group (heat-tolerant but cold-sensitive), i.e.
