The uniformity principle of temperature difference field is very useful in heat exchanger analyses and optimizations.In this paper, we analyze some other heat transfer optimization problems in the thermal management system of spacecrafts,including the cooling of thermal components, the one-stream series-wound heat exchanger network, the volume-to-point heat conduction problem, and the radiative heat transfer optimization problem, and have found that the uniformity principle of temperature difference field also holds. When the design objectives under the given constraints are achieved, the distributions of the temperature difference fields are uniform. The principle reflects the characteristic of the distribution of potential in the heat transfer optimization problems. It is also shown that the principle is consistent with the entransy theory. Therefore, although the principle is intuitive and phenomenological, the entransy theory can be the physical basis of the principle. 展开更多

Politeness is the badge of human civilization,and a significant criterion to human society activity; politeness,as a social phenomenon,is the imperative tool and method to maintain human relation in perfect harmony; politeness is a kind of social conventions,it lays certain restraints on all the social members. From ancient to modern times,either in East or West,people always attach great importance to politeness. To save face of the speaker or the hearer,politeness is of considerable practical significance in the conversation. As a matter of fact,its value can never be underestimated. However,due to different historical,lingual and cultural backgrounds,different societies may have different criteria to politeness. And this leads to some problems such as misunderstandings and embarrassments in cross-cultural or intercultural communication. In order to solve these problems,many scholars and linguists at home and abroad have proposed different principles of politeness so far. The author aims to make a comparative study on politeness principles between Chinese and English language and cultures. Analyzing the differences can help to remove the communicative barrier encountered by people who come from different countries with different cultural backgrounds and effectively promote further mutual understanding and cross-cultural communication. 展开更多

We present scheme I for solving one-dimensional fractional diffusion equation with variable coefficients based on the maximum modulus principle and two Grunwald approxima- tions. Scheme II is obtained by using classic Crank-Nicolson approximations in order to improve the time convergence. Schemes are proved to be unconditionally stable and second-order accuracy in spatial grid size for the problem with order of fractional derivative belonging to [(√17- 1)/2, 2] using the maximum modulus principle. A numerical example is given to confirm the theoretical analysis result. 展开更多

In this paper, we study an efficient asymptotically correction of a-posteriori er- ror estimator for the numerical approximation of Volterra integro-differential equations by piecewise polynomial collocation method. The deviation of the error for Volterra integro- differential equations by using the defect correction principle is defined. Also, it is shown that for m degree piecewise polynomial collocation method, our method provides O(hm+l) as the order of the deviation of the error. The theoretical behavior is tested on examples and it is shown that the numerical results confirm the theoretical part. 展开更多

For B2 NiAl and NiTi intermetallic compounds, the ideal stress–strain image is lack from the perspective of elastic constants. We use first-principles calculation to investigate the ideal strength and elastic behavior under the tensile and shear loads. The relation between the ideal strength and elastic constants is found. The uniaxial tension of NiAl and NiTi along <001> crystal direction leads to the change from tetragonal path to orthogonal path, which is driven by the vanishing of the shear constant C(66). The shear failure under {110}{111} shear deformation occurring in process of tension may result in a small ideal tensile strength(~ 2 GPa) for NiTi. The unlikeness in the ideal strength of Ni Al and Ni Ti alloys is discussed based on the charge density difference. 展开更多

In this paper,the maximum-principle-preserving(MPP)and positivitypreserving(PP)flux limiting technique will be generalized to a class of high-order weighted compact nonlinear schemes(WCNSs)for scalar conservation laws and the compressible Euler systems in both one and two dimensions.The main idea of the present method is to rewrite the scheme in a conservative form,and then define the local limiting parameters via case-by-case discussion.Smooth test problems are presented to demonstrate that the proposed MPP/PP WCNSs incorporating a third-order Runge-Kutta method can attain the desired order of accuracy.Other test problems with strong shocks and high pressure and density ratios are also conducted to testify the performance of the schemes. 展开更多

For solving two-dimensional incompressible flow in the vorticity form by the fourth-order compact finite difference scheme and explicit strong stability preserving temporal discretizations,we show that the simple bound-preserving limiter in Li et al.(SIAM J Numer Anal 56:3308–3345,2018)can enforce the strict bounds of the vorticity,if the velocity field satisfies a discrete divergence free constraint.For reducing oscillations,a modified TVB limiter adapted from Cockburn and Shu(SIAM J Numer Anal 31:607–627,1994)is constructed without affecting the bound-preserving property.This bound-preserving finite difference method can be used for any passive convection equation with a divergence free velocity field. 展开更多

The paper employs the method of discourse analysis to analyze males' and females' differences in cross-gender conversations in Gossip Girl from the perspective of Searle's Indirect Speech Act Theory, Grice's Cooperative Principle, and Leech's Politeness Principle. The study found that females tend to abide by Cooperative Principle, while males are more likely to fl out the CP, and that female characters are used to making requests or suggestions by raising question in a euphemistic way; while males concern less about courtesy, women always attach a great deal of importance to saving others' face in daily conversation. The paper contributed to reducing misunderstanding in cross-gender communication. 展开更多

The present study is intended to be an analysis of the main Romanian legal provision in what concerns the impact of foreign exchange differences and potential consequences at the level of financial statements for companies. In Romanian legislation, the issue of the foreign exchange differences is treated at a general level: these are recognized as a profit and loss item and as a consequence, they are included in the taxable base when booked in the accounting. Our legislation does not provide for specific treatments depending on the 'realization momenf' of these differences or depending on the conditions for recognizing a gain/loss from foreign exchange differences. For the unrealized exchange differences arising from the application of accounting rules on monthly assessment of foreign currency monetary items, there is not a specific event or transaction to determine income or expenditure. This monthly review depending on the National Bank of Romania [BNR] foreign exchange rate valid on the last day of the month aims to bring closer to reality the financial position of an entity. The exchange rate is a monetary policy item set by the central bank and may be influenced by various factors such as: monetary policy of the BNR; inflation target objectives and rate of exchange stabilization or reduction efforts, as is the case of BNR in the last years to fulfill EU criteria for adoption of the EURO; periodical influences of speculative capitals on the exchange rate level; economic status and especially exports and imports. However, a taxpayer should not be charged unless there is evidence of the "economic enrichment" thereof. However, this enrichment, seen as a rising economic value of the company, depends on the perspective from which is seen: the owner of the company or the tax authorities. The exchange differences impact also the value of the owners' equity for which a minimum level is requested under the commercial company law. In case of negative values, this triggers various risks at the level of the continuity principle or even endangers the existence of the company. 展开更多

As china's reform and opening up and the gradual establishment of market economy, we have been setting up more and more contact with the whole world. However, cultural difference is an obstacle for both sides. In order to communicate more convenient with western countries, translation is a necessary tool. With translation, we can do business more directly with other countries, improving our fame and comprehensive national strength. But if you want foreigners to purchase your products you have to translate your advertisement slogan which can make foreigners understand the advantages of your products. We can find that the slogan of an ad is often composed of only few words. But what it expresses is profound and lasting. When compile slogans, many rhetoric devices are used. Such as simile、repetition、parallelism and exaggeration. 展开更多
