It consists of the next three aspects: firstly, we study Murthys' open problem whether the augmented matrix is a Q0-matrix for an arbitary square matrix A , provide an affirmable answer to this problem , obtain the augmented matrix of a sufficient matrix is a sufficient matrix and prove the Graves algorithm can be used to solve linear complementarity problem with bisymmetry Po-matrices; Secondly, we study Murthys' conjecture about positive semidefinite matrices and provide some sufficient conditions such that a matrix is a positive semidefinite matrix, we also study Pang's conjecture , obtain two conditions when R0-matrices and Q-matrices are equivelent and some properties about E0 ∩ Q-matrices; Lastly, we give a counterexample to prove Danao's conjecture that if A is a Po-matrix, A ∈ E' A ∈ P1* is false, point out some mistakes of Murthys in [20] , obtain when n = 2 or 3, A ∈ E' A ∈ P1*, i.e.

本文分为三个部分，主要研究了线性互补问题的几个相关的公开问题以及猜想：(1)研究了Murthy等在[2]中提出的公开问题，即对任意的矩阵A，其扩充矩阵是否为Q_0-矩阵，给出了肯定的回答，得到充分矩阵的扩充矩阵是充分矩阵，并讨论了Graves算法，证明了若A是双对称的P_0-矩阵时，LCP可由Graves算法给出；(2)研究了Murthy等在[6]中提出关于半正定矩阵的猜想，给出了半正定矩阵的一些充分条件，并研究了Pang~-猜想，得到了只R_0-矩阵与Q-矩阵的二个等价条件，以及E_0∩Q-矩阵的一些性质；(3)研究了Danao在[25]中提出的Danao猜想，即，若A为P_0-矩阵，则，我们给出了反例证明了此猜想当n≥4时不成立，指出了Murthy等在[20]中的一些错误，得到n=2，3时，即[25]中定理3.2中A∈P_0的条件可以去掉。

Two specieses, Lycoris radiate and Lycoris aurea, were selected for the studying of artificial propagation in vitro. A few specieses of Lycoris, from the southeast area of China and part of locations in Japan, were chosen to research their karyotype differentiation and to measure their genetic diversity by ISSR analysis. The results could be summarized as follows.1. The vegetative propagation conditions of Lycoris aurea and L. radiate in vitro was studied by two-scaling. Different illuminate condition had an effect on the bulblet formation rate. To the species of L. radiate, the rate was higher in the state of 16h 800-12001x illumination than in the darkness. The medium also affected the new bulblet formating rate. When the culture was MS medium 0.2 mg/L NAA 4 mg/L 6-BA, the bulblet formationg rate of L. aurea was 220%;at the same time, when the medium was MS 0.2 mg/L NAA 2 mg/L 6-BA, the rate of L.
