As one of the hydrophyte, phytoplankton has a broad application.

同时，在河道水流有一定流速存在的水力特性条件下，水生植物是否可以达到预想的净化效果，这是我们急需得知的问题。

The deformation mechanism is mainly the single-slip and cross-ship, the fracture mechanism is mainly the congregation of transgranular micro-hole, and large uniform deformation occurred before tough fracture, and therefore, the ability of plastic deformation and the mechanical properties of the material were remarkably improved. These fully indicate that the new melt-treatment developed in this work is an effective and advanced technique, and further testify that the improvement of metallurgical quality of the material is the key to enhance its mechanical properties, especially its plastic deformation performance. The results of tensile and compression tests at elevated temperature also indicate that the suitable hot-working temperature range is 400～450℃. 4. A steady-state plastic flow exists during the plastic deformation of the aluminum sheet used for pressure can at elevated temperature. A hyperbolic sine relationship can be satisfied between the steady-state flow stress and strain rate by introducing an Arrhenius term which involves some thermal activation parameters, i.

压力罐用铝材中的主要冶金缺陷为Al〓O〓夹杂物、气孔及富Fe杂质相；高效熔体处理显著改善了材料的冶金缺陷的存在形态，使含杂量明显减少、夹杂物尺寸变细小且分布均匀，富Fe杂质相变为细小、分布均匀的团球状或短棒状的复杂化合物，同时也明显细化了结晶组织；此外，由于高效熔体处理有效地减少了材料中裂纹萌生源数量，因而改变了材料的塑性变形微观过程及断裂方式，主要以单滑移和交滑移进行塑性变形，断裂方式为穿晶微孔聚集型，韧性断裂前产生了大量的均匀变形，不易出现变形失稳，从而显著提高了罐用铝材的塑变能力和力学性能。

The relationship between the reflectivity and the position of stress is hyperbolic tangent. Moreover, the phase had certain relations. Based on this, the characteristic of FBG under inhomogeneous transverse force were studied.

同时，应用传输矩阵的方法对光纤光栅横向局部受力特性进行了研究，研究发现当光栅局部受力时，反射谱产生分裂，分裂点波长移动与受力大小成线性周期变化，分裂点的反射率与光栅局部受力位置为双曲正切关系，而且相位也存在一定的关系。

Today, all the known proxy digital signature schemes has the same problem that can't provide the overall, complete, reliable control ability on the stretch of proxy digital signature power. In this paper, we advances a new proxy digital signature scheme based on hyperelliptic curve discrete algorithmic problems which is called as Xiao's Hyperelliptic Curve Limited Proxy Signature.

本文针对目前的各种代理签名方案所存在的无法实现对代理签名者的代理签名权力进行全面、完整、可靠地控制的问题，提出了一种具有限制代理签名者行使代理签名权力的基于超椭圆曲线离散对数问题的新型可控代理签名方案XHCLPS，同时对这一方案的复杂性和安全性进行了分析。
