Ythagorean hodograph curves enjoy a number of remarkable properties, such as, its offset curves have exact rational representations; the arc length function of a Pythagorean hodograph curve is simply a polynomial function of the curve parameter; and the lower degree Pythagorean hodograph curves have intuitive geometrical interpretation.
H曲线具有诸如有精确的有理 Offset、弧长函数可由多项式函数表示以及几何解释优美等一系列优良性质。基于复分析方法，避免了实分析讨论中出现的复杂表示及繁琐计算，构造了满足给定 C1 Hermite插值条件且以C1拼接连续的三次 PH曲线偶。该曲线偶可灵活处理拐点，从而克服了一般三次 PH曲线因恒凸而无法处理拐点的缺陷。

It is proved that every Lie derivation of nest algebra is the sum of an associative derivation and a general trace. Every Lie isomorphism between nest subalgebras of a factor von Neumann algebra is the sum of an isomorphism and a general trace or the sum of a negative anti-isomorphism and a general trace. Lie invariant subspace of linear mappings on Banach algebras is introduced, and linear maps from nest subalgebra of a factor von Neumann algebra into itself which satisfy the property that the space of derivations is their Lie invariant subspaces are characterized. Simultaneously, it is shown that such maps are Lie derivations modulo the set of scalar multiple of the identity.
得到Lie导子的特征表示，即套代数上的任何一个Lie导子都是内导子与广义迹之和；给出了Lie同构和同构及反同构之间的关系，即因子von Neumann代数中套子代数之间的任何一个Lie同构要么是同构与广义迹之和要么是负反同构与广义迹之和；引入了Banach代数上线性映射的Lie不变子空间，并给出von Neumann代数中套子代数上以导子空间为Lie不变子空间的线性映射的一个刻画，同时也表明在模去数乘恒等映射的意义下，以导子空间为Lie不变子空间的线性映射就是Lie导子。

Three operators, the transpositional, identical and forward differential, are introduced firstly. Then the Bezier curve in conventional Bernstein-Bezier form is transformed to its operator form. Several properties of the curve are discussed in its operator form.
首先引入三个基本算子：移位算子、恒等算子和向前差分算子，然后将Bernstein-Bezier形式的Bezier曲线表示为更为简洁和直观的算子表示形式，并进一步讨论算子表示下Bezier曲线的各种性质，给出相关证明过程。

Tsunehiro Seamless steel prices, experts said in 2010 there will be more than 10% of the rise, and pointed out several reasons for this prediction: iron ore and coke and other raw materials prices; downstream of various sub-sectors of the demand-pull; the problem of excess production capacity to a certain degree of ease.
恒博无缝管专家表示2010年钢价将有10%以上的涨幅，并指出了此次预测的几个原因：铁矿石和焦炭等原材料价格的上涨；下游各子行业的需求拉动；产能过剩问题得到一定程度的缓解。

Heng Bo supplies seamless pipe, senior market analyst, said: At present the majority of iron inside the steel-making pig iron inventories not try for the impact of the demand by the steel mill, a lot of iron re-turn to the production of pig iron for steel-making, according to Iron Works to reflect , due to increased market demand for raw materials and coke prices up, market confidence has been restored, but the production of iron cast iron is still no intention to resume, the market demand will soar to a height of what the market is not expected to unity, on the current situation, the prudent operation of the steel-making pig iron is still the main way to run.
恒博物资的资深无缝管市场分析师表示：目前多数铁厂内炼钢生铁库存量不大，受钢厂需求拉升影响，很多铁厂再度转向对炼钢生铁的生产，据铁厂人士反映，由于市场需求加大和焦炭等原料价格的上行，市场信心有所恢复，但停产的铁厂暂时还没有恢复生铁的打算，市场需求会升到一个什么样的高度，市场预期并不统一，就目前的形势来看，谨慎操作依然是该炼钢生铁运行的主要方式。
