A few epidermal hairs distributed on the Costa of Lonicera Japonica Thumb. The upper epidermis of Solidago decurrens Lour were covered with sparse stellate hairs. The stomas distributed on the upper epidermis hairs of Lonicera Japonica Thunb, Lonicera confuse and Solidago decurrens Lour, which could reflect the sunlight and decrease the transpiration to adapt the highlight and drought environment;(2) The leaf blades of Polygala japonica butt were fleshy, and the sunk stomas distributed on both the sunk place of the upper epidermis and lower epidermis, which help to water conservation.

结果：(1)忍冬、华南忍冬、黄花草下表皮均分布浓密的表皮毛，忍冬上表面中脉有少量表皮毛，黄花草上表皮分布有稀疏的星状表皮毛，忍冬、华南忍冬和黄花草的气孔位于下表皮毛间隙，这种结构可反射阳光和阻止水分蒸发，从而适应强光和水分不足的环境；(2)瓜子金叶片为肉质叶，上下表面均有气孔分布，并出现明显的下陷。

Determinant Research Method is one of the effective methods for calculating the generalized eigenvalues and corresponding eigenvectors of a large sparse matrix. Its theoretical foundation is that for a symmetric matrix the leading principal minors of the eigenmatrix form a Sturm Sequence.

"行列式查找法"是计算大型稀疏矩阵广义特征值和特征向量的有效方法之一，其理论基础是对称矩阵的各阶顺序主子阵的特征行列式形成Sturm序列。

The original PageRank algorithm uses the Power Method to compute successive iterations that converge to the principal eigenvector of the Markov matrix representing the Web link graph.Authors use the sparse of the Google matrix P in the iterative matrix A =[ CP +（1- c ） E ]T,optimize the computation of each iteration and reduce storage space.

在PageRank算法中是使用乘幂法对网络链接图的Markov矩阵进行迭代计算，利用迭代矩阵 A =[ CP +（1- c ） E ]T中Google矩阵 P 的稀疏性，优化每次迭代的计算量并且减少空间存储量。

Then we will also put forward the complete security proof and we claim that there would be very high successful probability in our random sparse matrix DKG.

因此，为克服上述的瓶颈，我们提出一个架构於随机稀疏矩阵的分散式金钥产生机制，并提出在此架构下有非常高的成功机率以及完整的安全性证明；此外，我们所提的架构亦符合R。
