The results showed that 22.5μL/L of clove leaf oil had the best preservation effect on peach. After 35 days of stock, the sound fruit rate was 94%, 46.9% higher than compared group. The rotten index and the browning index were 94.1% and 85.2% lower than the control, respectivly, and the treatment could remarkablely reduce the respiration rate and ethylene release, and postponed ethylene release peak and respiration peak 5 and 10d, respectively in comparison with CK, it also delayed the drop of firmness and contents of titrable acids of the peach. When stored for 35d, firmness of control group and 22.5μL/L of clove leaf oil were decreased 60% and 34% compared with initial storage, and the activities of SOD, CAT and POD were enhanced, but the contents of SSC had no obvious difference with control.

结果表明，与对照相比，22.5μL/L丁香叶油处理对桃果实的防腐保鲜效果最好，贮藏35d时好果率为94%，比对照提高了46.9%，腐烂指数和褐变指数分别比对照低94.1%和85.2%；丁香叶油处理可以有效降低桃果实的呼吸强度和乙烯释放量，呼吸强度高峰和乙烯释放量高峰分别推迟5和10d，延缓了果实硬度和可滴定酸含量下降的速度；贮藏35d时对照和22.5μL/L丁香叶油处理果实硬度分别比贮藏初期降低了60%和34%；丁香叶油处理提高了超氧化物歧化酶、过氧化氢酶、过氧化物酶3种膜脂过氧化物酶的活性，但可溶性固形物含量与对照相比无明显差异。

Total soluble solids and titratable acid content were kept at high levels under I-MCP treatment.

溶性闯形物和可滴定酸含量，1-MCP处理还可以明显抑制梨黑皮病的发生，从而保持较高的好果率。

The results showed that 50℃ 20 min heat treatment had obviously decreased the rotten of fruits, and maintained higher soluble solid content, titratable acid and Vc contents of fruits after 60 days, and then improved the storage quality of fruits and prolonged the storage period of fruits.

结果表明：贮藏60 d后，50℃20 min热水处理明显降低了果实的腐烂率，维持了较高的可溶性固形物、可滴定酸含量和维生素C含量，从而改善了果实贮藏品质，有利于果实的贮藏保鲜。

The frist 3 characters based coefficient of variation are rate of two kernel (56.18%), single fruit weight (55.82%) and titratable acid 55.49

变异系数最大的前3个性状为：双仁率(56.18％)、单果重(55.82％)和可滴定酸55.49

The results indicated that 1-MCP treatment made fruit remain high quality and good flavor during storage by delaying the loss of firmness ,and maintain relatively high total soluble solids and titratable acid content.

结果表明：1 MCP处理可以明显延缓果实硬度的下降，维持果实较高的可溶性固形物和可滴定酸含量，从而较好地保持果实在贮藏期间的品质和风味；1 MCP处理可以明显抑制梨病害的发生，保持较高的好果率，并可降低果实丙二醛含量，延缓其衰老。

AMF-inoculation significantly increased the contents of total soluble solid, soluable sugar and titratable acid in fruit of cherry tomato.

结果表明：接种菌根真菌能够显著提高植株根系菌根的侵染率和果实干重；接种对品质的改善表现在果实中的可溶性固形物、可溶性糖和可滴定酸的含量明显提高，糖酸比适中，果实风味品质好。

The graft rate was determined to be 47~58% with linear titrimetric method.

同时，实验用线性电位滴定法测定其接枝率为47~58%。

The reaction mechanism, by-reaction inhibition, effect of initiator, and monomer on grafted products are studied extensively. Polyethylene grafted with maleic anhydride, as the hot melt adhesive for the aluminum-plastics compound pipe, is also studied as a goal for engineering application.

对反应挤出接枝体系进行了热分析，确定了合理的反应挤出工艺条件：用红外光谱和化学滴定的方法分别对接枝结构和接枝率作了定性表征和定量测定；对三种反应挤出体系的反应机理和副反应的抑制，以及引发剂、单体对接枝产物的影响进行了深入系统地研究；对PE接枝MAH作为铝塑复合管的热熔胶进行了工程化应用研究。
