In Chapter 5, we investigate the linear systems involving Kronecker product. We analyze its condition numbers and the level-2 condition numbers.

在第五章我们考察了带Kronecker积的线性系统，得到了与经典结果类似的条件数，并讨论了其二层条件数。

Seed of Podophyllum hexandrum Royle has the physiological characteristics of long dormancy and low germination in natural conditions. In order to investigate the characteristic of dormancy and find the mechanism of dormancy and the optimal method for breaking the dormancy of P.hexandrum seed, some methods such as isolated embryo cultures, biological identification, soaking seed in GA3, interaction GA3 and cold stratification were utilized.

摘要桃儿七种子在自然条件下具有休眠期长、萌发不良的生理特性，为了探讨和研究桃儿七种子的休眠特性，利用分离胚培养、生物鉴定法、GA3浸种、以及综合利用GA3和低温层积处理等方法。

Spinulosa seed is probably related to after-ripening of the underdeveloped embryos and released of the hard endocarp.

因此推测先予短暂的低温层积可增加种子内微量的内在激勃素浓度，再结合外在激勃素处理即可促进发芽。
