1·They've developed these sensors that can detect tiny amounts of ethylene.
他们已经开发了这些传感器，可以检测到微量的乙烯。
2·Ethylene is the natural plant hormone in fruit that makes them turn ripe, apparently.
很明显，乙烯是水果中天然的植物激素，使水果成熟。
3·Auxin also causes the plant to develop a vascular system, to form lateral roots, and to produce ethylene.
生长素还能使植物形成维管系统，形成侧根，并产生乙烯。
4·The preservative used is usually ethylene glycol or propylene glycol, as alcohol will evaporate quickly and the traps will dry out.
常用防腐剂是乙二醇或丙二醇，因为随着酒精快速挥发，捕集器也随之恢复干燥。
5·Reaction of the isocyanic acid (HNCO) and isothiocyanic acid (HNCS) with ethylene radical is studied.
研究了异氰酸及异硫氰酸与乙烯自由基之间发生的反应。
6·Polymers of ethylene, in primary forms.
初级形状的乙烯聚合物。
7·A univalent chemical radical derived from ethylene.
从乙烯衍生而来的一价化学基。
8·Apples, for example, release ethylene gas, a plant hormone.
例如苹果，释放出乙烯气体，这是一种植物激素。
9·Such reactions to ethylene are consistent with ancient reports.
这种对乙烯的反应和古代的一些报道是一致的。
10·Plants all produce ethylene, a ripening gas that promotes maturation.
植物会产生乙烯，这是一种促进植物老化的催熟气体。

5·Apples, for example, release ethylene gas, a plant hormone. It can cause other foods to ripen too quickly.
例如，苹果释放乙烯气体——一种植物激素，会引起其它食品过早成熟而腐烂。
