To protect the identity of orchid cultivar and the right of the breeders, we successfully develop a novel method by the introduction of foreign DNA sequence (27bp) as molecular marker via BioWare low pressure gene gun into Mormodes lawrence and Zygopetalum mackayi. Histochemical GUS transient expression was obtained from aleurone layer and embryo of Zea mays using BioWare low pressure gene gun with acceleration pressure of 50psi. This is the first report on successful transfer into plant tissue using BioWare low pressure gene gun.

本研究的目的为利用核苷酸排列组合之多样性，设计一段27个碱基对序列来代表品种所有者注册资料，经由国人自行研发之生物镓低压基因枪，利用50psi的氦气压力，将设计好DNA序列标志转殖至妖精兰与轭瓣兰品种，使其实生或分生之子代，皆会具有此注册片段，品种权所有者可以具体以PCR或定序分析确认DNA序列标志，作为保障种源权之认证系统。

With Ammonia as refrigerant and water as absorbent, they are boiled by the heater in the generator, as a result, the Ammonia-water solution is evaporated. The Ammonia vapor is purified by the rectifier and is condensed into liquid Ammonia in condenser. The liquid Ammonia and the pure Helium purified in the absorber are evaporated together in the evaporator and to absorb heat thus refrigerate at the same time.

采用氨为制冷剂，水为吸收剂，通过对制冷机芯的发生器加热，使氨水溶液中的氨蒸发，氨蒸汽经精馏器提纯后进入冷凝器成液氨，液氨在蒸发器中与经吸收器提纯的纯氦共同蒸发，同时从外部吸收热量，达到制冷的目的。
