马车越空噪音越大500字作文英文回答:The assertion that an empty carriage makes more noise than a full one is a common misconception that can be attributed to several factors. Firstly, the acoustic properties of an empty carriage differ significantly from those of a full one. The presence of passengers and cargo inside the carriage dampens the sound waves produced by its wheels and chassis, reducing the overall noise level. Conversely, an empty carriage lacks this dampening effect, allowing the sound waves to resonate more freely and generating a louder noise.Furthermore, the weight distribution of an emptycarriage can contribute to its increased noise levels. When a carriage is loaded with passengers and cargo, the weightis distributed more evenly, resulting in a smoother ride. However, an empty carriage is unbalanced, causing thewheels to bounce and rumble more, creating additional noise.It is important to note that the size and design of the carriage also play a role in determining its noise levels. Larger carriages with heavier wheels are generally louder than smaller ones. Additionally, the type of suspension system used on the carriage can influence its noise output. Carriages with rigid suspension systems tend to be more noisy than those with softer, more flexible suspension systems.In conclusion, the assertion that an empty carriage makes more noise than a full one is generally true, as the absence of passengers and cargo reduces sound dampening and increases the impact of the wheels on the ground. However, the specific noise levels of a carriage can vary depending on its size, design, and suspension system.中文回答:马车越空噪音越大的说法是一个常见的误解,可以归因于几个因素。
马车越空噪声越大作文审题英文回答:The louder the carriage, the emptier it gets. This saying perfectly describes the phenomenon of the noiselevel increasing as the number of passengers in a carriage decreases. I have personally experienced this on a subway train during off-peak hours. When the train is packed with people during rush hour, the noise level is relatively low as everyone is engaged in conversations or simply minding their own business. However, during quieter times whenthere are only a few passengers on board, the noise level seems to rise significantly. This is because the absence of conversation and other ambient sounds makes any noise, such as the rumbling of the train or the squeaking of the wheels, much more noticeable. It's as if the emptiness of the carriage amplifies every little sound, creating a cacophony that is absent when the carriage is full.中文回答:马车越空,噪音越大。
