First of all , visual documentation , a century - long approach recorded by video camera , does have advantages that written records could never compete : motion pictures , simultaneous audio recording , dynamic and direct view 首先，影像记录（这种通过摄像机完成的，仅有仅一个世纪历史的方式）具有文字记录不可比拟的优势：活动画面、现场声音、动态感和直观性。
Application of fuzzy comprehensive assessment in highway project can quantify evaluation . it is helpful to decrease investment risk and enhance economic benefit , so it is very meaningful and practical to real project 模糊综合评价方法在公路工程项目投资中的应用,使项目的评价定量化,具有相对的直观性,对于减少投资风险,扩大经济效益,具有非常汇总要的现实意义和使用价值。
An economical teaching skeleton with full natural movement and a user - friendly personality that will encourage children to learn the names of the bones , with details to satisfy students , doctors or anyone interested in the human skeleton 这是一款经济型的教学模型，可模拟人体运动，直观性强。它让孩子们有兴趣学习骨头的名称，使学生、医生和其他对模型感兴趣者感到满意。
In this algorithm , the intuitionistic property is assured by using the binary image as the watermark ; discrete cosine transform and classical edge detection algorithm are adopted to determine the imbedded zones for the watermark 在此算法中，以二值图像作为水印，具有较强的直观性；利用经典的数字图像处理技术中的离散余弦变换和边缘检测算法确定水印嵌入区域并完成水印嵌入。
This essay insists that object teaching and comprehensive designed experimental teaching should be strengthened in chemistry teaching according to its teaching features , which can foster students ' creative thought and fully develop the function of right brain 本文主张在化学教学中，根据本学科的教学特点，加强直观性教学和综合设计性实验教学，培养学生创造性思维能力，使右脑的功能得到充分开发。
Using the geometric properties and algorithms for degree elevation of bezier curves , a new algorithm is gave for bezier curves based on the genetic algorithms , which has the virtues of uncomplicated and high precision and obvious geometric property 第三应用b zier曲线几何性质和b zier曲线的升阶公式，基于遗传算法，给出了b zier曲线的降阶的新算法。与已有算法相比，该算法计算简单、精度高、几何直观性强。
With the development of network technology , internet has transformed our lives and the way we communicate , how we learn , how we work and spend free time , in essence ? it has more or less changed every aspect of human society one can think of 近年来,随着互联网技术的发展和普遍应用,网络越来越影响人们的生产生活方式。由于视频信息具有直观性强,内容丰富等特点,因此视频传输在网络传输领域占据了越来越重要的地位。
Written documentation , a traditional method with a thousand - year history , is inevitably falling into the weakness of being in - direct and is more likely mingled with subjective standpoints of the writer , which may cause the readers receive partial or unfair information 而文字记录，这种已经延续了数千年的传统记录方式，不可避免地缺乏直观性，而且容易掺杂记录者的主观立场，使得阅读者不能得到最全面和公正的信息（画面） 。
It shows the functional relationship between the instantaneous voltage and time . the intuitionism and particularity of the oscilloscope are outstanding compared with other electronic instruments . therefore , technicians in test and measure prefer to use it 它以图示的方式把电路中的瞬间电压同时间的函数关系描绘出来,其测试的直观性和细致程度是其它测量设备不可比拟的,所以是工程技术人员进行测试和故障检修时的首选工具。
