The results showed that N^+ beam-induced mutation of maize pollens can result in the change of their DNA bases. The mutation is not properly random and its frequency increases with a rise in 30 keV N+ beam doses. It is conformed with A-G transformation, which is one of the most important factors in DNA bases induced by N+ beam.展开更多

The average number of laser shots is 20.5(1～127 shots), and the average shot energy is 2.5 mJ(0.9～5.6mJ). The successful rate of iris penetration is about 97.6%. The size of the iris hole is not smaller than 0.2mm^2. The kind of the iris is the most important factor that causes the marked variation in laser shots and in laser shot energy. The main complications of Nd:YAG laser iridotomy p...展开更多

Seen from the geotectonic position, it belongs to North Tianshan geodome system, Tianshan diwa region, Central Asian crustobody. Copper and zinc polymetallic ore bodies had been formed in the skarn of the contact, between the metamophic carbonate rocks of the Kuximqiek Group, Jixian System and early mid Varisean acidic rockbodies. The formation of the ore deposit was the result of the successive activities of the crust and mantle and the tectonic and magmatic activities.展开更多

The results are as follows: The maximal spectral response of the b-wave in protanopes tended to shift toward the short wavelength side and the sensitivity to long wavelengths decreased obviously. The ratio value of the amplitude in 500nm and in 620nm(500/620) was greater in the protanope than that in the normal subject. Like the normals, the maximal response of the b-wave in deuteranopes appea...展开更多
