  2. As result, a new method is presented by using the acoustic emission ( ae ) signal from stem of individual plant as its demand information. based on virtual instruments technique, which is becoming a popular tool in measurement and automation fields international, a computer - based detecting system is developed for the fast, real - time measurement. take tomato crops for testing example in greenhouse, the relation between ae and transpiration, environmental factors has been studied

    因此，從植物本身出發，本文在國內首次採用了以植株莖部聲發射信號作為農作物需水信息的新方法，運用目前在測控領域國際流行的虛擬儀器技術，建立了對作物植株莖部聲發射信息進行實時、快速測量的微機檢測系統，並以溫室盆栽番茄為對象，研究了聲發射信息同植物蒸騰以及環境因子間的關系。
  3. Abstract : in order to obtain the mechanical properties of cemented soil, a series of cemented soil specimens with different cement ratios are conducted through uniaxial compression tests and ultrasonic wave tests. the link of the compressive strength of the prismatic specimens and the cubic ones is established. the relationship between the uniaxial compressive strength and the speed of ultrasonic wave of cemented soil specimens are acquired

    文摘:本文通過室內抗壓實驗及超聲波波速實驗的方法，對不同水泥摻入比下水泥土的力學性能進行了研究，獲得了水泥土材料稜柱體抗壓強度與立方體抗壓強度之間的關系，以及抗壓強度與波速之間的關系式。
