Audiophile values may be applied at all stages of music reproduction: the initial audio recording, the production process, and the playback, which is usually in a home setting.

"发烧"的观念可体现在音乐制作的各个阶段：初期的音频录制、制作过程，以及录音回放等，而回放阶段通常在家中进行。

The cinema is very bad to search, put a half to give breakdown to go back replay... need memory ability remembers gut, it is a common Hollywood is big so, do not understand why to so much person can buy the ticket of 150, do so that be like ~~~ to appreciate Shanghai one week with Culture Revolution, the Sun Ganlou that still has Shuai Shuai and the film review after all editor ~~~ are small salon, be present possibly mix with respect to me wild goose is not liberal art one's previous experience, they have the blueness that nod anger literary cell, saying is almost,"I feel this film not up to much "... so that Xiang Siwei needs authority later,those who who likes this movie look in light of raise one's hand... wild goose likes 3D, apparent love hate is trenchant, touch field, vigorous speech so " reader "(she is raise one's hand, the 囧 that does not need an editor to call-over), it is this ask her to see a stage play again.

影院很不好找，放了一半出了故障倒回往重放……需要回忆才能想起剧情，所以就是部普通的好莱坞***，不懂为何会有那么多人往买150的票，搞得跟***似~~~感谢上海壹周，还有帅帅的孙甘露及所有编辑~~~之后的影评小沙龙，可能在座的就我和大雁不是文科出身，他们都有点愤青文艺细胞，说起来几乎都是，"我觉得这电影不怎么样"……以至于项斯薇后来需要大家举手来看看有谁喜欢这部电影的……大雁喜欢3D，很明显的爱恨分明，如此碰场、积极发言的"读者"（她是举手的，不需要编辑点名的囧），是该再请她往看话剧了。

Especially, the technology of Automatic Gain Control and signal processing are studied which are key factors working on the performance of the receiver. Based on analyzing the theory of automatic Gain Control, operational amplifiers 0P37 and logarithmic D/Aconverter AD7111A are used to design variable gain amplifiers which can be controlled numerally, A/D convector LTC1405 is Used to test the echo, Complex Programmable Logic device is used for controller, and an arithmetic is designed for automatic Gain Control which is simulated and analyzed in order to test its feasibility.

本文在分析自动增益控制AGC原理的基础上，采用集成运放OP37和数控增益衰减器AD7111A设计可数字控制的可变增益运放模块；采用高速A／D转换器LTC1405作为回波信号检测模块；采用复杂可编程逻辑器件CPLD作为核心控制模块，构成数字自动增益控制电路，并设计粗调和细调步进控制相结合的算法，对回波信号的增益进行精确而快速的调节控制，使回波信号振幅快速稳定在设计指标范围内，利于接收机后续信号处理电路对回波信号作进一步的处理。

Heat up again the wok with the rest oil, add in onion and stir fry until fragrant. Add carrot and stir fry for 1 minute, then add in bell pepper and black fungus, return the spaghetti and seasoning, stir till all ingredients well-mixed.

把剩下油放入烧热，放入洋葱炒出香味，加入胡萝卜翻炒1分钟后加入甜椒和黑木耳，把面条回锅翻炒，加入调味，翻炒完全均匀后盛起。

The mathematical relationships among mixed layer thickness, ore recovery and waste dilution against drawpoint spacing, volume per drawing, cut-off waste dilution and level interval are studied in details. It shows that the contact face between ore and waste as a ideal interface is incorrect during drawing.

以二次回归正交放矿计算机仿真实验为研究手段，以单一采场放矿为研究对象，详细地阐明了混杂层厚度、矿石回贫指标与漏斗间距、一份放出量、截止废石混入率及阶段高度之间的数学关系；研究指出：在放矿过程中，将崩落矿岩接触带视为一理想界面是不正确的。

As a downstream piping system when the valve opens, reflux valve, when closed, the main medium used to prevent backflow to prevent the pump and drive motor reversal, as well as a container medium discharge; currently the most commonly used is the valve flap around the body Swing Pin rotation flap valve and the valve body along the vertical axis to move lift check valve, but the above two kinds of structures exist in the valve closed, medium speed back quickly from the largest drop to zero, inlet side of the pipe resulted in the rapid pressure rise, resulting Proportional Pressure Reducing Valves in damaging effects on the piping system of water hammer phenomenon, it is generally a diameter of valve production of 50 ~ 500 mm.

止回阀作为管道系统顺流时开启，逆流时关闭的阀门，主要用于防止介质倒流，防止泵及驱动电机反转以及容器内介质泄放；目前使用最普遍的是阀瓣围绕阀体销轴旋转的旋启式止回阀和阀瓣沿着阀体垂直中心线移动的升降式止回阀，但以上2种结构的阀门均存在关闭时介质倒流速度从最大迅速降为零，致使管道进水管一侧内压迅速升高，从而产生对管路系统有破坏作用的水锤现象，所以一般止回阀生产口径为50～500 mm。

A right cheerful epistle," said Friar Tuck , when he had finished reading,"and I doubt not that it will please our Robin to hear it read again. Put all the goods back on the mules, lads, and trouble not whether there is a stray finger nail or a shoe lace or two over, after this.

多愉快的书信，」当塔克修道士念完时说：「我确信再念给我们的罗宾听，会令他更高兴，年轻人，将所有的货物放回骡上，之后，不管有偶见的指甲，或者鞋镶边或者两者都有，也不用担心。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
