B: Um, I think for us it just was something… we heard of it, and for us as a band it's of course good that we, with the music, because we're in the spotlight, can do things, can engage for things… And I think that it's a big topic, and especially with really young people… and, ehm… um… I mean, I know this: Tom is my brother, who also started pretty early with these things… It's just a big topic, and we thought, like, to combine that with a T-Shirt and to make a big campaign out of it, we really liked that, and of course it's an awesome message - and that's why we took part.

我觉得作为一个乐队，这对我们当然大有好处，用音乐，因为我们处在闪光灯下，我们可以有所作为，投入某件事，而且我觉得这是个严肃的主题……尤其是对于年纪特别小的年轻人………那个……嗯……啊……我是说，我知道这点，tom是我哥嘛，他老早就有这档子事么……这个主题很严肃……而且我们想……通过设计t-shirt来发起一场声势浩大的运动，我们真得很喜欢这个，当然这也是一个非常棒的信号，这就是我们为什么参与了这个行动。

Acting as an antenna molecule in the supramolecular system, Mg(superscript 2+)-HA remarkably enhances the photoinduced electron transfer efficiency between C60 and an electron donor, N, N-dimethylaniline.

作为超分子体系中的光捕获分子，Mg(上标 2+)-HA能显著地提高C60与N，N-二甲基苯胺的光诱导电子转移反应效率，生成的C60负离子自由基的电子自旋共振光谱信号强度比未加入Mg(上标 2+)-HA时增强了9倍左右。

This digital thermometer design uses the American DALLAS Semiconductor Company after DS1820 promotes one kind of advanced version intelligence temperature sensor DS18B20 takes the detecting element, the temperature measurement scope may amount to 0.0625 degree Celsius for the - 55--125 degree Celsius biggest resolution, may the direct readout measure the temperature to plant, moreover used the three-wire system and the monolithic integrated circuit is connected, reduced the exterior hardware circuit, has at the same time the characteristic which the low cost and easy to use it to have the microminiaturization, the low power loss, the high performance, the anti-jamming ability strong, easy to match merits and so on microprocessor, the especially qualify in constituted the multi-spot temperature observation system, might directly the temperature inversion serial digital signal for microcomputer processing, moreover each piece of DS1820 had onlyThe product number and may store in its ROM, in order to constitution large-scale temperature observation system time hangs on the single track meets willfully many DS1820 chips.

本数字温度计设计采用美国DALLAS半导体公司继DS1820之后推出的一种改进型智能温度传感器DS18B20作为检测元件，测温范围为-55——125摄氏度最大分辨率可达0.0625摄氏度，可以直接读出被测温度植，而且采用三线制与单片机相连，减少了外部的硬件电路，具有低成本和易使用的特点同时它具有微型化、低功耗、高性能、抗干拢能力强、易配微处理器等优点，特别适合于构成多点温度测控系统，可直接将温度转化成串行数字信号供微机处理，而且每片DS1820都有唯一的产品号并可存入其ROM中，以便在构成大型温度测控系统时在单线上挂接任意多个DS1820芯片。
