黄土高原典型灌草植物根系生物力学特性及其相互关系

Shuitu Baochi Xuebao
目的为探究不同灌草植物根系生物力学特性的差异性及其相互关系。方法选取黄土高原地区6种常见的水土保持灌草植物，系统研究其根系形态、化学成分和抗拉力学特性及其相互关系。结果1）6种灌草植物根系直径（D）主要以细根（<2 mm）为主，根长密度（RLD）、根表面积密度（RSAD）和根生物量密度（RMD）不同土层深度分布呈显著差异性（p<0.05）；白羊草的D、RLD、RSAD和RMD与其他5种植物存在显著差异性（p<0.05）。2）6种植物根系平均抗拉强度（Tr），白羊草根系平均Tr分别是苔草、

翼状胬肉临床评估指标与其眼表改变相关性分析

Zhongshan Daxue xuebao. Yixue kexue ban, 2012
摘要： 【目的】 探讨原发性翼状胬肉大小、透明性等常用临床评估指标，分析其与翼状胬肉眼表损害的相关性。【方法】 随机选取于2010年5月至7月，在中山眼科中心门诊就诊的初发的原发性翼状胬肉患者55例（71眼），其中男性26例（32眼），女性29例（39眼）；记录翼状胬肉的大小（mm2）、生长时间(年) 、 透明性（T1~3级）。行结膜印记细胞学检查，记录翼状胬肉患者的结膜杯状细胞计数（个/视野）及上皮形态改变级别（0~3级），计算各临床评估指标与结膜印记细胞学检查结果的相关系数。【结果 ...
