Results show that the nanometer particles are in spherical shape, the size of particles is homogenized and controllable, no agglomeration. The particle size changes with the processing condition; the maximum particle size is in the range of 80~90 nm, and the minimum particle size is in the range of 25~30 nm. The ice performance test in indoor cloud chamber shows that the nanometer silver iodide particles as catalyst for artificial weather modification have great application prospect.

In this research, the ~ and F2 of the crosses between a natural mutant 慪34?with super-minute grain and 慪38?with super-large grain,慡huhui 881擲huhui 527?with middle grain size were carried out to study the inheritance of the grain shape (grain length, grain width, grain thickness and grain length/width ratio) and 1000-grain weight. The main results are summarized as below:? The F1 grain length, grain width, grain thickness and 1000-grain weight of three crosses were lay between the two parents and tended to Y34, which indicated that those grain traits were all governed by the dominant effect of Y34 and influenced by both female and male parents. The differences of F1 grain length, grain width, grain thickness and 1000-grain weight of positive and negative crosses between Y38 and Y34 indicated the existence of cytogene effects.? The broad heritabilities of major grain traits were calculated.
