Firstly we maked sure method of isolating arabidopsisis mutant by thermal imagings in many ways on trial, optimize conditions for isolation, and confirm the good period of seedlings and fine density for isolation, select correct isolating pressure ( drought and h2o2 ) that is fit for isolate mutant. secondly we obtain an ml population derived from 0. 4 % ethyl methanesulfonate ( ems ) - mutagenized wild type arabidopsis thaliana
本實驗首先是對利用遠紅外成像技術篩選擬南芥突變體方法的可行性進行多方面的試驗，優化篩選條件、確定篩選所需幼苗的生長時間、種植密度，界定用於篩選所需的脅迫（過氧化氫和乾旱）選擇壓力。 -
In order to promote the population of the new technology, hecad software was developed by thermal energy research center of zhengzhou university. as a 2d cad drawing software, it realized the automatic design of process design, mechanic _ al design, components design and assembly drawing design of thelfsf. however, along with the development of software and hardware and the evolvement of design thought, not only 2d drawing but also 3d solid modeling is needed in modern design of heat exchang _ er ' s parts
Hecad系統在零部件二維圖形和總裝圖的自動化繪制上取得了很大成就，但隨著計算機軟硬體技術的發展和設計理念的演變，在對換熱設備零部件進行二維設計的同時，需要機械產品的三維實體模型，而且在零部件三維模型基礎之上，設計者可以對設計模型進行工程有限元分析，得到其工況下的真實溫度場和應力場的分佈，以便使設計者能及時對零部件模型的設計缺陷進行修改和優化，最終設計出性能合格、重量較輕的理想產品。
