This result tells us that the key letter method is a more efficient strategy than the rote strategy in learning English vocabularies, and it tells us that we needn't pay much for the opportunity cost for key letter method learning either.

这表明，关键字母法策略比机械复述策略对于英文词汇的记忆，具有较大的促进作用，学习关键字母法的机会成本也是较低的。

Based on the results of the experiment, the results indicate as follows (1) the opportunity cost for key letter method learning of a fifth-grade student of an elementary school is 77 minutes of time;(2) the learning of the relations between letters and their chief representatives have a great transference effect on the learning of the relations between letters and their deputy representatives, and this result told us that the opportunity cost for key letter method learning could be reduced by learning and mastering first the relations between letters and their chief representatives.

实验结果表明：(1)小学五年级学生学习关键字母法的机会成本约为77分钟；(2)字母—正代表关系的学习结果，对于字母—副代表的学习具有较大的迁移作用。这说明，先学习并牢记字母—正代表关系，能够减少关键字母法的机会成本。

MCP could effectively delay the softening of climacteric fruit, such as Starking and Fuji apples and Feicheng peach, but as different fruits had different softening mechanism, the mechanism of 1-MCP inhibiting different fruit softening was different: in Starking apples, the key enzyme to the softening is endo-and exo-PG, while during Feicheng peach fruit softening, the key enzyme was EGase before the 20th d and endo-PG after 20th d during storage at 0℃. 1-MCP inhibited fruit softening mainly by inhibiting PG activity in Starking apple while in Feicheng peach, by inhibiting the activity of EGase in the earlier storage time and endo-PG in the latter time. It was also found that LOX accelerated the initiation of the softening and was regulated by ethylene and 1-MCP in apple and peach.

2.1-MCP能较好的延缓红星、富士和肥城桃等跃变型果实硬度的下降，但是不同品种/树种的果实软化机理不同，1-MCP抑制其软化的机理也不一致：在红星果实中，对软化起主要作用的酶一直为内切和外切两种PG，而在肥城桃软化过程中，前20d以纤维素酶活性起主要作用，20d后软化以内切PG为主。1-MCP主要通过抑制红星果实中PG酶活性来抑制果实硬度的下降；在肥城桃果实中，1-MCP通过抑制前期纤维素酶和后期内切PG活性，延缓了果实硬度的下降。
