试驾广州本田新款雅阁2.4i-VTEC

新雅阁的外形极具动感，其前部设计更为圆润，三角形的前大灯与车头线条以及新型格栅很是吻合。     

航道整治工程必须实行动态管理

自上世纪90年代以来，随着财力的增加，国家加大了对长江航道建设的投入，一些重电水道航道整治工程相继开工建设。长江属于大江大河，影响航道的因素十分复杂．在航道整治实施过程中，必须因势利导，实行动态管理。笔者拟结合长江航道整治工程实践，对实施动态管理的必要性进行论述．并对规范的管理模式和可操作性的管理办法作些初步探讨。     

撞车了， 咋办呢

事故回放“老张开车去东北,撞了;肇事司机耍流氓,跑了……”下班后,小王哼着这首歌,开着轿车回家。车是行驶在右车道上,就在经过小区大门的时候,突然,逆向冲出一辆皮卡,“啪嚓嚓”几声,硬是把轿车的右前脸及侧部撞了;接着“砰砰”几声,小王在里面也被撞昏过去了。还好,都是同一个小区的,皮卡车主老周知道出事故了,急急地下车,看看对方有没有事。老周一边迅速地扶起小王,一边

Application of digital image correlation method to in-situ dynamic strain measurement

Application of digital image correlation (DIC) method to determination of in-situ dynamic strain is presented in this study. Firstly, an integrative software is programmed based on the DIC algorithms and point-wise least-squares fitting technique. Then, simulated speckle images are generated to study the computational accuracy of this software. The experimental setup and procedures for measuring in-situ dynamic strain through both DIC and strain gauge are proposed. The DIC results are close to those measured by strain gauge. This fact reveals that DIC is a practical and effective tool for in-situ dynamic strain measurement. Finally, the full-field in-situ dynamic strain of another specimen is measured by DIC, and the overall distribution of the strain in the measurement area is clearly shown.
