It has been deduced that the search direction remains the same but that the step length decreases in optimizing the improved cost function with the conjugate gradient algorithm from the gradient of the cost function that the FIR filter apporaches the contrary point spread function more, and that the estimated image is closer to the original one.

从代价函数的梯度入手推导出共轭梯度算法，其搜索方向保持不变而搜索步长变小，使滤波系数更加逼近于点扩展函数逆算子，从而使估计图像与原始图像更加接近。

Cupper atom is formed by means of the decomposition of CuBr into Cu;++, and then recombination of Cu;++. Consequently the recombination coefficient is bigger and the delay time of laser pulse gets longer when the working temperature is lower.

由于工作物质铜原子是通过分解CuBr成为铜离子，再由铜离子复合成铜原子，故工作温度较低时，复合系数较大，造成激光脉冲的延时时间变长，而当工作温度较高时，复合系数变小，使激光脉冲提前。

Outdoor advertising posters exposure in daylight easily fade away, you'd want to light characteristics of the ink. The same is blue ink, phthalicacid cyan than light light turquoise blue,孔雀蓝 and hard to change colour.

A recombinant protein of Bla g 2 has been obtained, which is soluble in the supernatant and therefore can avoid a process of denaturalization and renaturation of the recombinant.

获得了真核表达的德国小蠊主要变应原重组蛋白Bla g 2，该蛋白以可溶性蛋白的形式分泌到培养液中，避免了原核表达的变复性过程。

In order to improve the accuracy and comparability of hardness and elastic modulus measurements in nanoin- dentation, an evaluation of the creep behavior and its influence on the mechanical properties of the electrode- posited nickel film has been conducted.

为提高纳米压痕测量硬度和弹性模量结果的准确性和可靠性，对其蠕变行为进行评价是很必要的。蠕变依赖于材料本身的性质并在几秒之内降低到一个很小的值。

As the world gets smaller and smaller, it becomes even more important for us to dig into these roots.

随着世界变得越来越小，它变得更加重要的是我们能够深入探讨这些根源。

In the single crystal of C60 with a FCC structure,positron mainly appears outside the C60 molecule.The main annihilation space is the interspace between molecules.The calculated positron bulk lifetime in C60 is 352ps, which agrees with experiment value of 356ps in literature.In carbon nanotube bundles with different dimeters,as the diameter of carbon nanotubes increases,the main space where positron appears changes from the interspace of carbon tubes to the space inside carbon tubes,the radio between positron annihilation with valence eletrons and core eletrons becomes larger,the positron bulk lifetime in carbon nanotube increase rapidly first and come to be a constant at the end.The calculated positron lifetime of carbon nanotube with a dimeter of 0.8～1.6ns is 332～470ps,which agrees with the experiment value of 394ps.Positron annihilation has been studied in widly used compound semiconductors.

计算结果表明：在片层结构的石墨晶体中，正电子主要在石墨层间的空隙中湮没，计算出的石墨中的正电子寿命为208 pS，与文献中的实验结果215 ps符合很好；在金刚石单晶中，正电子主要在碳原子之间的空隙中存在并发生湮没，计算出的金刚石中的正电子寿命为115 ps，文献中的实验结果110 ps左右符合；在面心立方结构的C60晶体中，正电子主要在C60分子球壳内外侧及分子之间存在，C60球形分子中心正电子分布很少，正电子的湮没区域集中在C60分子之间的空隙区域，计算出的C60中的正电子寿命为352 ps与文献中的实验结果356ps相符合；对于不同管径碳米管束中的正电子分布，随着碳纳米管直径的增加，碳纳米管束中的正电子由主要在碳纳米管管间的区域出现转变为主要在碳纳米管管内中心的区域出现：碳纳米管束中的正电子与碳原子的价电子的湮没概率变得越来越大，与核心电子的湮没概率变得越来越小；碳纳米管束中正电子的湮没寿命先迅速增大，而后趋于一定值。
