Compared with similar advanced equipment, FPP Series mill has advantages as follows,① Adding the cutting and grinding function;② Extend the time of material pressing and cutting and grinding;③ Solve the sensitivity of keeping the proportional spacing and proportional thickness;④ Widened material input size;⑤ Material output size are in a perpetual state;⑥ Multifunctional machine is used to dry and grind and filtrate material;⑦ Auxiliary equipment is less and covering is small and investment is small;⑧ Noise is low and dust is small, it is beneficial to protect environment and keep physical and mental health for operation workers.

FPP 型系列磨机的结构形式是电机拖动减速机带动磨盘旋转，带有压力的磨辊在磨盘上自转，对物料进行碾压，磨内的物料在旋转离心力的作用下均匀进入碾磨区，磨辊对物料实施挤压、剪切、研磨，故破碎能力大，粉磨能力强，与同类先进设备相比：①增加了剪切研磨功能；②延长了物料挤压剪切研磨时间；③解决了对物料粉层均匀一致，厚度一致的过于敏感性；④拓宽了对物料的进料粒度；⑤物料的出料粒度永远处于受控状态；⑥可以对物料进行烘干、粉磨、筛分一机多能化；⑦辅机设备少、占地小、投资省；⑧噪音小、扬尘点少，有利于环保和操作工人的身心健康。

Having used the pyrophyllite of Mentougou, Beijing over 40 years, the mineral now is almost run out. therefore, through the technological innovation to study and adopt a new type of medium of transferring press to lower the production cost and increase the economic benefit has already become the main issue focused by the line and strategic subject of the constant development in the line and other relevant lines.

在延续使用40多年的北京门头沟叶蜡石矿床面临枯竭的情况下，通过技术创新，研究和采用一种新型的传压介质，降低生产成本，提高经济效益，已经成为行业关注的重大问题，是本行业和相关行业可持续发展的战略性问题。

Next day, i asked the people in Ad. Department, only to get such an answer, someone found them and spent money to buy a period of time (the more expensive the period of time is, the better it is). They provided a broadcasting manuscript and a voice phone number, then started such a fraud. They smiled helplessly. They had no other choice. Advertisement mission press hardly, and everyone is now broadcasting, those cheaters were doing this quiz game in almost all places, including television, radio. Now advertisement is not easy to sell, it has to do on.

第二天我问了下广告部那帮人，得到了这样的一个答案，有人找他们，花钱买一个时段，，提供一个播音稿，提供一个声讯电话号码，就开始了这样一个骗局，他们无奈的笑答，没有办法呢，广告任务压头，再说现在大家都在播，那些骗子几乎在所有的地方做这个竞猜，电视台、电台都在做，现在广告也不好拉，有做就接呢。

The three-rotor single phase variable voltage and speed motor possess the advantages of simple control, low price, and a wide range of variable speed, particularly good condition for heat scatter in lower speed running.

三转子单相调压调速电动机具有控制简单、价格低廉、调速范围宽等优点，尤其在低速运行下有较好的散热条件。

Ransack my car but found nothing, just a Bonuslink card appear in front of me after it's lost for a month ago.

简直可以把车子给翻了，找到的，却是1个多月前，突然宣告失踪的Bonuslink卡，原来压在车座下。

The conventional numerical simulation of a reverberant field as a launch acoustic environment was introduced. Following the reciprocity theorem used in the coupled FE-BE model, the structural response due to reverberant acoustic excitation was substituted by the sound pressure caused by force excitation on the structure, then the output response power spectrum density of the coupled model subjected to reverberant environment was evaluated based on the stochastic analysis principle.

首先介绍了传统的构建混响声场的数值模拟方法；其后利用声振耦合中的互易定理，将混响声场的激励问题转化为结构模型上力激励引起的场点声压响应问题，并采用随机分析原理，用谱分析方法推导了结构在混响声场激励下的响应计算公式；最后建立了航天器典型结构的声振耦合模型，并分别用传统方法和利用互易定理的方法进行了数值模拟。

The RB-SL2 is a stereo, or twin independent mono, VCA limiter for use in news-rooms and other locations where the correct level into recording equipment is required, but not necessarily under the control of an engineer, for example, for overload protection.

RB-SL2为一台立体声或双独立单声道的压控放大式限幅器，在无需技术人员控制的情况下，能自动做音量过荷的限制保护，适用于新闻报导或需矫正电平的录音工作等。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
