In the computational methods of TPBVP, in order to reduce some difficulties involved in solving a TPBVP via adjoint variables, we discuss a direct method in which state and control variables are indirectly parameterized, The method employs a recently developed direct optimization technique that uses a piecewise polynomial representation for the state and control variables, thus converting the optimal control problem into a nonlinear programming problem, which can be solved numerically.

在数值解法中，为了减少解决两点边值问题共轭变量带来的困难，主要讨论了将状态变量和控制变量进行参数化的一种直接方法，这种方法采用了近段发展起来的使用分段的多项式来代替状态和控制变量的直接优化方法，然后最优控制问题就转化成可以用数值方法解决的非线性规划问题，使得迭代初值更加容易选取。

The system chart of designing a weather radar with SZ phase code is listed, the principal and coding series of this kind of SZ phase code is illustrated.

首先给出了该方法应用到某气象雷达上所采用的系统框图；然后介绍了SZ相位编码的原理和编码序列以及基于这种编码给出了气象雷达解距离模糊算法的详细流程，并着重介绍了频谱重构的频域处理方法；最后给出了用该方法同时解出一次和二次气象回波的Matlab仿真，结果表明该方法对平均速度的估算较为准确。

Electrochemical oscillation of lead electrode in sulfuric acid has been explored with in-situ ellipsometry.Effects of improvement of electrodes properties are affected by increase or decrease of surface temperature of the samples badly during ion implantation. Some theories and methods on substance diffusion transfer have been applied to calorifics to obtain mathematical relation between the surface temperature on the samples and operation time during ion implantation.

掠射式椭圆偏振方法是本论文提出的一种全新的研究方法，为验证这种现场研究方法的可行性，本论文选择了几个用其它方法研究较为成熟的电化学体系并结合本论文研究的化学电源体系，以掠射式椭圆偏振技术进行研究，提出了改良镍电极、锌电极、铝电极和铜电极性能的具体措施或者理解这些电极表面性质和涉及它们的电极过程的实验依据，为使用这些电极的化学电源性能的提高奠定了基础。

Edgewax: Waxing method recommended for lubricating release prints; treatment is with a solution of 50 grams of paraffin wax per litre of trichloromethane applied only to the edges of the emulsion side of the film.

用封腊的方法来润滑用于发行的拷贝；这种方法是用每升三氯乙烷溶解50 克石蜡形成的溶液，只用于处理胶片的乳剂面的侧缘。

I have been there for many times to do sketches. The cracked old roots and fissures of the truck touched the bottom of my heart again and again. In the painting "Cypresses in the Forbidden City", I used a so-called method of scattered dots to depict the fissures which is extremely rare in similar paintings, while for the walls I used the crimpling skills to reveal its weathering nature. It is because I believe that all techniques and effects should be centered on the main themes, to make paintings more profound in humanism.

我曾无数次地到那一带去写生，那苍茫的老树根，那干裂的树纹肌理，曾一次次地触动我的心扉，《皇城古柏》这幅画我用散笔法来表现柏树的纹理效果，由上至下，气韵贯通，这种方法在画柏树里并不多见，用打点的方法来点树叶，层层打点积厚，但又注意疏密的关系对比，形成密不透风，疏可走马的效果，而皇城的城墙我则采取皱纸法来做出墙面的沧桑肌理效果，以此来传达出皇城这一历经风雨的历史厚重感，我的创作理念是：一切技法和效果为主题服务，让画面丰富起来，让画面融入人文内涵。

Jackson's essay Tolerant but Unaccepting: The Myth of a Thai 'Gay Paradise' but am less concerned with foreign misconceptions of Thai social life than the currency of this sexualized imagery, which I examine in terms of a dialectic between the production of and resistance to forms of stereotyping.

的文章，即《容忍但不接受：一个泰国&男同性恋乐园&神话》（ Tolerant but Unaccepting： The Myth of a Thai 'Gay Paradise'），但是，我的分析较少关注西方对于泰国社会生活的错误观念，而更多考虑这种关于性的想象的传播。在这种传播过程中，有对形象的刻板化的生产，也有对这种生产的抵制。我用辨证方法探讨了两者的关系。

However, the quasi-human method can give us good strategies for jumping out of a trap of local minimum with the help of human beings\' behavior and experiences.A new 3-dimensional real Euclid model is proposed for the protein structure prediction problem. Then a quasi-physical method based on corresponding physical model is presented to solve the relevant mathematical problem.

拟物方法将原始问题落实为优化问题，而在用数学方法求解优化问题时，常常会碰到计算落入目标函数局部极小值陷阱的困境，如何从这种困境中逃逸出来，使得计算奔向前景更好的区域，拟物方法则无能为力，而应用拟人方法则可以设计出好的&跳出陷阱&的策略。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
