freezing stress meaning in English

冻结应力

Optimum properties for frozen stress analyses are obtained with the following compositions .
下列配合比的性质，最宜于冻结应力分析。
Besides , 5 % methanol enhanced the resistance to freezing stress in the sensitive species , and this effect seems to be related to maintenance of the psi activity and energy transfer between pigment protein complexes by methanol
值得注意的是5甲醇提高了非抗冻型品种synechocystissp . pcc6803的冻结耐性。其作用机制可能是在冻结胁迫下保持ps活性和色素蛋白复合体之间的能量传递。
Tolerance to and effects of the freezing stress in a desiccation - tolerant , terrestrial cyanobacterium , nostoc commune , and in a desiccation - sensitive species , synechocystis sp . pcc6803 , were studied by measuring their photosynthetic activities and fluorescence emission spectra
通过检测光合成活性和荧光发射光谱等研究冰结胁迫对蓝藻地衣( nostoccommune )和单细胞集胞藻( synechocystissp . pcc6803 )的影响。
