Auditory Brainstem Response, ABR (or Brainstem Auditory Evoked Potentials, BAEP) is a human body physiology parameter at microvolt level. First, we use the TMS320F2812 of TI company, making the signal through D/A transform and high accuracy operational amplifier, and produce the masking white noises, as well as the Tone Burst to be the stimulus. Then, the evoked EEG will be amplified and filtered. At the same time, we use the A/D of TMS320F2812 to collect and process the signals, and get the digital BAEP.

听觉脑干诱发电位(Auditory Brainstem Response，ABR)为微伏级人体生理参量，采用TI公司的DSP TMS320F2812，通过D/A与高精度运算放大器，生成听力级可调整的掩蔽白噪声与短纯音TB进行刺激，同时对诱发脑电进行放大、滤波、并使用TMS320F2812的A/D进行信号采集与处理，得到数字化的脑干诱发电信号。

It is proved that all monic polynomials of order n with roots lying in some open region on the complex plane forms a simply connected set in the polynomial parameter space. Based on this result, Edge Theorems for D-stability of general polyhedrons of polynomials and Boundary Theorems for D-stability of compact sets of polynomials are obtained.

The reducing sugar content of potatoes also increase during the sun drying of grapes and dates, sucrose is converted to d-glucose and d-fructose; accordingly, the color of the dried products is deepened by nonenzymic browning reactions.

马铃薯在冷藏间还原糖含量也会增加。葡萄和海枣在晒干期间，随其内源蔗糖酶活性的不同，会不同程度地使蔗糖转化d-葡萄糖和d-果糖。因此，其干制品的颜色也会因非酶褐变而加深。

We find that the orthorhombic distortion leads to a secondorder coupling term between the d-and s-wave order parameters,which results ina nonvanishing s-wave component even in a uniform system and a mixed d+s-wave pairing state.

正交畸变使得GL自由能密度泛函中包含了d波与s波序参量的二阶耦合项。这一项的存在使得即使在空间均匀的情况下也会有非零的s波成分存在，并且导致d+s混合波配对态。

The standards specify several types of end user access circuits, each of which involves one or more B channels and one D channel. The B channels are for circuit-switched user communications, and the D channels are primarily for signaling and control (e.g., on-hook and off-hook signaling, ringing signals, performance monitoring, synchronization and error control).

该标准详细列出了几种终端用户电路类型，每一种类型包含一个或多个B信道以及1个D信道。B信道用于电路交换用户通信，D信道主要用于信令和控制（例如挂和摘机机信令、振铃信号、性能监控、同步以及错误控制）。
