125. The time - resolved neutron flux density measurement system on HT - 7 Tokamak is presented in the paper.

126. While the evolution of the macro world is highly related to the nuclear reaction of micro world, can neuron theory also successfully predict that there exists no "organism consists wholly of neutron"?

127. The calibration ratio of CNLT5420 compensate neutron logging tool is the key parameter to determine the validity of porosity value.

128. Scientists use virus neutron as cannonball to bombard the cell genetic nuclide, observing whether or not it can go through the cell reaction while producing some untapped artificial radionuclide.
