After 30 days, the cultures were preserved in darkness, and 4 types of resting cysts were found after another 90 days:(1) spherical to ovoid cysts (25-39 μm long) covered by asparse or numerous calcareous attachments (1-4 μm long) and a calcareous surface;(2) spherical cysts (29-35 μm diameter) with a noncalcareous surface attachment, calcareous surface;(3)spherical to ovoid cysts (29-35 μm long) w ithout any surface attachment and a calcareous surface; and (4) spherical c ysts (24- 35 μm diameter) without any surface attachment and an organic surf ace.

培养30天后，培养液中有大量休眠孢囊，将藻液避光保存90天后，观察到培养基中有4种类型的休眠孢囊产生：(1)球形到椭球形(长25-39 μm)，钙质外壁，稀疏或密被钙质附属物(长1-4 μm)；(2)球形(直径为29-35 μm)，钙质外壁，附属物非钙质(长0.5-1.5 μm)；(3)球形到椭球形(长29-35 μm)，钙质，表面光滑，无附属物；(4)球形(直径24-35 μm )，有机外壁，无附属物。

For solving nonlinear optimization problems, Newton-like method is one of the most efficient methods and it is an important problem to improve the method.

在大规模稀疏非线性最优化的研究中，Newton型方法一直受到人们的青睐，对它的改进一直是人们关注的问题。

This feature leads to overlong and sparse bit vectors of BV algorithm, which requires a large amount of storage resources and too many read cycles in network processor.

在大型网络中大量的规则数量会导致位向量算法的位向量过长和稀疏，要在网络处理器中实现BV算法需要大量的存储资源，而且多次存储读取也降低了算法匹配效率。

Simulations show that, with an appropriate "overproduce and choose" strategy or "thinning" algorithm, the proposed BAM ensemble significantly outperforms the single QLBAM in both storage capacity and noise tolerance capability.

计算机仿真表明，选择合适的"过剩生产与挑选并存"策略，即"稀疏算法"后，所提出的BAM集成在存储容量和抗噪声性能两个方面都显著优于单个QLBAM。
