We watched many programs in the television set.

All cases were diagnosed as BH4 deficiency by analysis of urinary pterins profile, BH4 loading test, and determination of dihydropteridine reductase in RBC.

所有患者均经尿蝶呤谱分析、BH4口服负荷试验及红细胞二氢蝶呤还原酶测定，确诊为BH4缺乏症。

For example, in the separations of purines, pyrimidines and pterins to these compounds on MSP, hydrogen-bonding interaction played leading roles besides hydrophobic interaction.

例如，在厚朴酚键合硅胶固定相（MSP）中分离嘌呤、嘧啶及蝶呤时，除了疏水性作用外，氢键作用还发挥着重要作用。

By comparing the performance of two prototypes, it was discussed how the load current and output voltage of front stage ( input voltage of back stage) influence on the efficiency of DC/ AC inverter, then the basis for the circuit optimization was obtained.

通过两台原理样机的性能比较，讨论了负载电流、前级输出电压（后级输入电压）对逆变器效率的影响，为优化设计电路提供了依据。

In circuit design of linear potentiometer, owing to the influence of input and output impedance for front and back stage circuits, and its absurd installation, linear potentiometer will cause nonlinear response. It makes to fall short of precision of circuits and control system.

在线性电位器的电路设计中、电路前后级的输出和输入阻抗的影响以及使用与安装不当都可能引入非线性，造成电路和控制系统的精度达不到要求。

Once on the stage, she can leave behind at the back stage all pains from her ailment and her sorrows.

只消在台上，她把病痛和悲伤的外衣脱下，挂在后台。

Analog front-end circuit consists of preamplifier, low pass filter circuit and back stage amplifier circuit, preamplifier circuit instrumentation amplifier is used because it has a high input impedance, high common mode rejection ratio ( CMRR), low noise, and low drift.

模拟前端电路由前置放大电路、高低通滤波电路和后级放大电路组成，前置放大电路用的是仪表放大器，因为它有高输入阻抗、高共模抑制比（CMRR）、低噪声、低漂移。

The back stage control center is mainly for audience device interactive control at beginning and process of the concert by the organizers, including the relay layout debugging before the start of the concert and other functions.

舞台后台控制中心主要为演唱会主办单位在演唱会开始和进行过程中，对场馆观众终端进行实施互动控制，包括演唱会开始前的中继布局调试等功能。

But just when other artists started walking along the star corridor in the rain, I was told that I could go to the back stage to have my interview of Anita Mui.

然而，就在众多明星开始在雨中踏上星光大道时，我被告知可以到后台对梅艳芳进行采访。

You look fantastic.Thank you, so do you. I just said that back stage, that's sweet.thank you
