This study investigated the effects of different concentration GA3 on Aralia continentalis Kitagwa seed germination under fluctuating temperature(25℃/5℃),temporal changes inα-amylase activity at 150mg·L-1 GA3 during stratification were determined.

mairei seeds during cold-warm-cold stratification treatment was studied in this paper.

For the low guality and high cost of wear structural parts,especially gear wheel,the new technology of variable temperature and low pressure carborization is indicated.

The property and the constitution of phase of nitrided layer of 25Cr2MoV steel which is nitrided by ordinary ion nitriding and new process of vapid and deep-case ion nitriding in variable temperature respectively have been studied with microhardeness apparatus and X-ray diffratometer.
