The experiment was performed at the Asterix IV iodine laser with a prepulse 5 ns before the main pulse. Under optimum focusing conditions for main pulse and prepulse the X-ray laser beam splits into two beamlets along the target surface at its output end of the 2.5 cm long plasma column. The splitting was still observed when the prepulse alone was defocused.

实验发现在抽运激光主、预脉冲最佳聚焦条件下， X射线激光束在2.5 cm长的线状等离子体输出端沿靶面方向分裂成两束；在抽运预脉冲单独散焦条件下，仍然观察到这一分裂现象；但是当抽运主、预脉冲同时散焦时，这一分裂现象逐渐消失并获得了半宽度只有40 μm的非常窄的近场像。

Calculate the total volume, in cm , of the three cuboids.

以cm 为单位，计算这三个长方形的总体积。

The optimal conditions for electroporation transformation of Pichia Pastoris were obtained with the maximum transformation efficiency of 36 transformants/μg plasmid DNA when the intermediate logarithmic phase yeast cells were used for competent cells, and the electroporations were under the conditions of voltage of 1.5kV and 0.15mg / mL plasmid DNA and 0.2 cm cuvettes.
