The Determination of Conversion Condition of Convertible Bonds Based on the Investor s Risk Preference;

This paper is to investigate a class of Sturm-Liouville operators with transmission conditions and spectral-parameter in two boundary conditions.

To investigate a class of singular Sturm-Liouville problems with transmission conditions and spectral-parameter in one boundary condition,a self-adjoint linear operator A is defined in a suitable Hilbert space H such that the asymptotic analysis of such problem are transformed into those of operator A.

Relationship between fertility alteration of fertility-changing sterile plant of nucleus male sterile line Kang A_1 and temperature in cotton;

7 ℃ during their sensitive stage to temperature for fertility alteration.

This paper reports the study of fertility alteration character of Pingxiang Dominant Genic Male Sterile Rice under na- ture condition and in phytotron.

The mechanism of fertility conversion of temperature sensitive genic male sterile line in maize was studied by the methods of sowing with stages and investigating leafage.

Temian S-1 was used as studying material, this paper studied rules of growth and development of the male sterility in natural environment, the effects of average diurnal temperature, and different sunlight on fertility conversion, mechanism of fertility conversion at different temperature.
