    • A method for measuring moisture content in a biological material in an automated procedure is disclosed. The method comprises the step of: providing a reference database for a plurality of different material types with known moisture content. Further, a sample of biological material, such as chips of wood, pulp, grain, crop or sugar canes, are scanned with electromagnetic radiation of at least two different energy levels and the amount of radiation transmitted through the sample of the biological material is determined at said two energy levels. Subsequently, a material type in the reference database most resembling the biological material of the biological material of the sample is identified, and the moisture content of the sample of biological material is determined based on the identified material type and the determined amounts of radiation transmitted through the sample.
    • 公开了一种在自动化程序中测量生物材料中的水分含量的方法。 该方法包括以下步骤:为具有已知水分含量的多种不同材料类型提供参考数据库。 此外,用至少两个不同能级的电磁辐射扫描生物材料样品,例如木材,纸浆,谷粒,作物或甘蔗的碎片,并且确定透过生物材料样品的辐射量 在两个能级。 随后,确定参考数据库中最类似于​​样品生物材料的生物材料的材料类型,并根据识别的材料类型和确定的辐射透射量确定生物材料样品的水分含量 例子。
