大中型水利工程项目大多采用平面闸门、弧形闸门、人字闸门、反弧门等设计,但由于工程项目存在差异,国家原有的技术标准无法囊括新工程和新情况。为保证水利工程质量,在实际施工中必须对闸门的施工技术提出高要求。文章以广西红水河桥巩水电站工程为例,对水利工程闸门的技术安装与质量控制进行了探讨。 相似文献

在Lab-Corder测量太阳电池伏安特性实验中,只要改变二个可变电位器的负载大小,就可以完成本实验的数据测量.但Lab-Corder采集到的数据及图形往往不是很理想,达不到预期的结果.在实验过程中如何进行才能得到我们想要的实验结果呢?在本实验中实验的技巧是至关重要的一环,本文重点探讨其实验的技巧及方式方法对实验的结果影响. 相似文献

We apply a quadratic hedging scheme developed by Föllmer, Schweizer, and Sondermann to European contingent products whose underlying asset is modeled using a GARCH process and show that local risk-minimizing strategies with respect to the physical measure do exist, even though an associated minimal martingale measure is only available in the presence of bounded innovations. More importantly, since those local risk-minimizing strategies are in general convoluted and difficult to evaluate, we introduce Girsanov-like risk-neutral measures for the log-prices that yield more tractable and useful results. Regarding this subject, we focus on GARCH time series models with Gaussian innovations and we provide specific sufficient conditions concerning the finiteness of the kurtosis, under which those martingale measures are appropriate in the context of quadratic hedging. When this equivalent martingale measure is adapted to the price representation we are able to recover the classical pricing formulas of Duan and Heston and Nandi, as well as hedging schemes that improve the performance of those proposed in the literature. 相似文献

This work addresses the problem of optimal pricing and hedging of a European option on an illiquid asset Z using two proxies: a liquid asset S and a liquid European option on another liquid asset Y. We assume that the S-hedge is dynamic while the Y-hedge is static. Using the indifference pricing approach, we derive a Hamilton–Jacobi–Bellman equation for the value function. We solve this equation analytically (in quadrature) using an asymptotic expansion around the limit of perfect correlation between assets Y and Z. While in this paper we apply our framework to an incomplete market version of Merton’s credit-equity model, the same approach can be used for other asset classes (equity, commodity, FX, etc.), e.g. for pricing and hedging options with illiquid strikes or illiquid exotic options. 相似文献

This paper evaluates changes made to the internal assessment component of a third year financial accounting course at a university in New Zealand. A learning portfolio was designed to supplement existing coursework. The aim was to engender in students a deep rather than a surface approach to learning. As a record of the students' learning, the learning portfolio was an attempt to produce an innovative development in the assessment of what was a traditionally taught financial accounting course. Within their learning portfolios, students were required to complete a number of tasks, each aimed at improving critical thinking skills and creativity. Students were also required to maintain a personal or reflective section aimed at personalising and deepening the quality of their learning. 相似文献

香港"轨道交通+土地综合利用"的模式是一种集地铁投资、建设、运营和沿线土地综合开发于一体的综合开发模式,是由港铁统筹开发的。从运作流程上分为项目谋划、项目明确、项目开发和项目运营四个阶段,在营造高效率的公共交通体系、促进土地高度集约、节约利用等方面都取得了明显效益。对我国城镇交通发展有五点启示和借鉴:(1)交通规划与土地规划同步进行、有机结合;(2)推进经营性土地有偿使用;(3)运用节地技术和模式,充分发挥土地的复合利用功能;(4)分层出让,实现土地利用的多元化价值;(5)拓展融资渠道,实现轨道交通多渠道投融资。 相似文献

由于英汉两个民族有着不同的文化背景和思维方式,植物隐喻存在着相似性的同时也存在着差异。在英汉互译时,产生了可译性、相对可译性与不可译性的现象。译者应选择恰当的翻译方法和技巧,尽量准确地表达源语言的含义。 相似文献

Joseph Heath 《Journal of Business Ethics》2008,83(4):595-614
The prevalence of white-collar crime casts a long shadow over discussions in business ethics. One of the effects that has
been the development of a strong emphasis upon questions of moral motivation within the field. Often in business ethics, there
is no real dispute about the content of our moral obligations, the question is rather how to motivate people to respect them.
This is a question that has been studied quite extensively by criminologists as well, yet their research has had little impact
on the reflections of business ethicists. In this article, I attempt to show how a criminological perspective can help to
illuminate some traditional questions in business ethics. I begin by explaining why criminologists reject three of the most
popular folk theories of criminal motivation. I go on to discuss a more satisfactory theory, involving the so-called “techniques
of neutralization,” and its implications for business ethics.
