  2. Finally, nasa and the florida space research institute are sponsoring moonrox, the moon regolith oxygen competition. a 250, 000 prize goes to the team that can extract 5 kg of breathable oxygen from jsc - 1 lunar stimulant, a new lunar soil simulant developed under the auspices of nasa johnson space centre, in 8 hours

    最後，美國太空總署和佛羅里達太空研究中心，正贊助一項名為月球表土氧氣的賽事，提供25萬美元獎金給率先在八小時內能從美國太空總署莊臣太空中心的模擬月球土壤jsc - 1提取5公斤可呼吸氧氣的人。
  3. Now some universities and institutes of china have made some samples of the lunar rovers and theirs wheels, but until now the wheel ’ s mechanical performance is seldom researched and tested. this paper will analyze the mechanical performance of the wheel and design a test - bed to test the performance of the lunar rover ’ s wheel. firstly, the mechanical characters of the soil are separated to press - sinkage character and shear character based on bekker ’ s theory, and common press - sinkage and shear models are introduced and the theory of lankine passive earth pressure is also introduced

    根據bekker半經驗法的基本思想，將土壤的力學特性分解為水平方向的剪切特性和豎直方向的承壓特性，闡述了地面力學中常見的土壤的承壓、剪切等力學模型，並引入了朗肯被動土壓力理論，為建立車輪在松軟土壤中前進和轉向的力學模型奠定了基礎，同時進行了實驗土壤的剪切實驗，測量了土壤的內聚力和內摩擦角等參數。

    鈦鐵礦在地球和月球均普遍存在，而mls - la是仿照月球土壤成份把蘇必略湖北岸數以億年的玄武巖和玻璃顆粒混合而成。
  5. Lunar surface can be regarded approximately as two - layered medium composed of lunar soil and lunar rock. therefore, in this paper, two - layered medium is mainly discussed

    月球表層可近似視為由月壤和月巖組成的雙層結構，因此，本文主要針對雙層媒質進行討論。
  6. The aim of this paper is to find a method to estimate the thickness of lunar soil from the values measured by lunar microwave radiometer

    本文的主要目的是尋找一種反演方法，利用月球探測衛星微波輻射計的亮度溫度數據評估月壤厚度。
  7. A review and prospect for developing of lunar soil simulants

    模擬月壤研製的初步設想
  8. Simulated soil is used instead as it is too costly to use actual lunar soil at this stage

    由於真正的月球土壤太昂貴，在這階段不宜作研究之用。
