Indium has a melting point as low as 156℃. It forms many kinds of low melting temperature eutectic solder with Sn, Pb, Ag,etc. Indium base solder shows excellent oxidation resistance towards alkaline media. Its wettability on metal and
市场都已经朝着75bp去走,50bp早就price in的事情,收回最近预期75pb那段跌了一个寂寞,缩表部分也低于预期,缩的还相对温和,好处就是五月流动性极速收缩暂时解除,坏处就是通胀继续高挂,而我们会不会涨...不一定。但是起码不会暴跌,港股也跌了一个寂寞,今天恒生反包a股刚好也能收一个小阳,但是我们的问题还是在于...
Elastic electron-scattering cross sections from Pb have been measured for 0.5 fm<q<2.24 fm. The charge distribution for this nucleus is determined by a "model-independent" method; it exhibits a bump in the center of the nucleus which is also a characteristic feature of Hartree-Fock calculation...
Cuban, American and European cigars contained low levels of Pb. Cigars from the remaining countries contained twice as much Pb. The mean Po/Pb ratio showed an excess of polonium. In the case of a one cigar-a-day smoker, the calculated annual absorbed dose due to Po is -16 mGy. 展开 ...
