在显微镜之下，原本看起来很干净的表面其实像砖墙一样凹凸不平，如果这堵墙看起来破烂不堪或疏松易碎，就说明珍珠层没有用。
Under the microscope, the stuff they're after looks like a clean, structurally sound brick wall. If the wall looks ratty or crumbly, it's no good.
目的：骨质疏松症是以骨量减少、骨组织显微结构退化为特征，以至骨的脆性增高及骨折危险性增加的一种全身性骨病。
Objective: Osteoporosis is characterized by a decrease in bone mass as well as a deterioration of the bone architecture resulting in an increased risk of fracture.
目的：寻求一种骨小梁显微图像参数自动提取的方法并将之应用于骨质疏松症中。
AIM: to find out a bone trabecular micro image parameter self obtained method and to apply it in osteoporosis.
前言： 目的：骨质疏松是指单位体积骨量的减少与骨强度的降低。骨量减少和骨显微结构受损既而引起骨脆性增加的系统性骨科疾病。
Objective:Osteoporosis means that the bone weight per unit volume and bone strength reduce. which induce systematic osteonosus for increase of bone fragility.
