通过算例比较表明，实用计算式可简便并偏于安全地计算正放四角锥网架结构的临界温度。

The calculated example shows that the practical equation can calculate the critical temperature for regular pyramidic space trusses.

因此，选育不育临界温度低、育性相对稳定的实用光温敏核不育系，探讨不育系育性转换规律、育性遗传规律及生理生化特性，在理论和实践上都具有重要意义。

So it is very important for the theory and practice to research and insight the fertility alteration, fertility inheritance and physiological and biochemical characters of PTGMS lines.
