Beginning with analysis on basic features, visual form and grain - size distribution of gel particles, expansion multiple,viscoelasticity and other characteristic parameters were researched.

In this study, a total of 259 F2:3 families, derived from the cross between a dent corn inbred Dan232 and a popcorn inbred N04, were evaluated for their popping folds in replicated ex-periments under two environments.

In this stuty, NILs for two QTL of 100-grain weight (qGW1 and qGW3) and one NIL for QTL of popping fold (qPF1) were constructed using Marker-assisted selection (MAS) according to the QTL identified in F2:3 population, respectively.

The intumescent times of super-thin and thin steelstructure fire-retardant coatings were tested with the test method of the intumescent times.

The intumescent times of super-thin and thin steel-structure fire-retardant coating and latex intumescent coating were tested with the test method of the intumescent times.

A New Way for Raising the Magnification of Anatomical Lens

Based on dynamic characteristic about torsional vibration of the main drive system of Baogang 2050 hot steel F1 continuous rolling mill,actual measure and theory calculation are realized, natural frequency and torque magnification of the mills are gained, relevant conclusions are drawed.

The magnification is found to be dependent significantly on the value of measurement.

Analysis of improving amplification stability on a negative feedback amplifier;

In order to tackle the difficult problem that the computational complexity of super-resolution image reconstruction rapidly and exponentially increases with the increase in amplification, this paper proposes a general fast super-resolution image reconstruction algorithm, in which the translation relation of multi low-resolution images is used to divide the images into several groups.

It can automatically change its amplification with the control of a single chip computer so that the output can vary within proper limits.
