In this paper,corn straw in north cold climate regions are takenas the research object.With using the experimental method of orthogonal design,the straw size,bulk size,bulk density and moisture content are taken as influencing factors.Experiments are did on the self-made test bed in order to study the smoldering characteristics of the sectional corn straw in north cold climate regions.The results show that when the straw size is 350mm,the bulk size is 250mm×350mm×300mm,the bulk density is 40kg/m3 and the moisture content is 20%at that time the temperature in oven cavity is high,and the time of smoldering is the longest.The highest average temperature is 701.6℃,and the time of smoldering is 145min.The smoldering wave is from top to bottom.The change in temperature is from top to bottom,and gradually increased.This phenomenon belongs to a forward smoldering.

叶绿体是高等植物进行光合作用的场所,其正常发育依赖于细胞核基因和叶绿体基因的协调表达,这些基因的突变将导致叶绿体发育的缺陷及光合特性的改变。在我们的工作中,分别对两个水稻白化突变体albl和alblhc2的光合特性进行了研究,并对突变基因进行了图位克隆和功能分析,结果如下:1.水稻白化突变体albl的基因定位和功能研究通过X-射线诱变,我们获得了一例水稻白化突变体albl,该突变体在幼苗时期表现为
