高度测量法

The whole process of the experiment was visualized and recorded in the tape through an intravital fluorescent microscopic system. The dynamic process of thrombus formation was digitized using a multimedia computer system. With a specially developed image processing software, initiation time of thrombus formation, totally occluded time, and the time course changes of normalized thrombus length, thrombus height, cross area, thrombus surface area and thrombus volume were measured quantitatively. Besides, the growth rate of platelet thrombus in this thrombosis model was discussed.

利用视频多媒体系统和自行开发的计算机图象处理系统，对血栓生长的动态过程进行图象的采样、处理和分析，定量测量了血栓开始形成时间、血栓完全栓塞时间，以及归一化后的血栓长度、血栓高度、血管狭窄截面面积、血栓表面积和血栓体积等指标的时变曲线，并对光化学法致栓模型中血小板血栓的生长速度进行了讨论。

Maria taught them to use the sextant , an instrument measuring the height of the sun from the horizon, and then to calculate the position of a ship through the use of mathematics and celestial navigation .

玛丽亚教他们使用六分仪，这是一种测量太阳离开水平线高度的仪器，后来又教他们通过数学和天体导航法的应用来推算船只的位置。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
