Plt tokamak
In 1934, Mark Oliphant, Paul Harteck and Ernest Rutherford were the first to achieve fusion on Earth, using a particle accelerator to shoot deuterium nuclei into metal foil containing deuterium or other atoms. This allowed them to measure the nuclear cross section of various fusion reactions, and determined that the deuterium–deuterium reaction occurred at a lower energy than other reactions… Web@@ 传统观点认为,急性胰腺炎(AP)血淀粉酶(Amy)2～12 h开始升高,下降较快;尿Amy 12～24 h才升高,持续时间较长,后期测尿Amy更有价值.该文对1 h尿Amy排泄量与AP的关系进行了探讨,并与浓度测定进行对比.
