摘要：Based on the thermal network of the two-dimensional heterojunction bipolar transistors(HBTs) array, the thermal resistance matrix is presented, including the self-heating thermal resistance and thermal coupling resistance to describe the self-heating and thermal coupling effects, *** HBT cells along the emitter length direction, the thermal coupling resistance is far smaller than the self-heating thermal resistance, and the peak junction temperature is mainly determined by the self-heating thermal ***, the thermal coupling resistance is in the same order with the self-heating thermal resistance for HBT cells along the emitter width ***, the dependence of the thermal resistance matrix on cell spacing along the emitter length direction and cell spacing along the emitter width direction is also investigated, *** is shown that the moderate increase of cell spacings along the emitter length direction and the emitter width direction could effectively lower the self-heating thermal resistance and thermal coupling resistance,and hence the peak junction temperature is decreased, which sheds light on adopting a two-dimensional non-uniform cell spacing layout to improve the uneven temperature *** taking a 2 × 6 HBTs array for example, a twodimensional non-uniform cell spacing layout is designed, which can effectively lower the peak junction temperature and reduce the non-uniformity of the dissipated *** the HBTs array with optimized layout, the high power-handling capability and thermal dissipation capability are kept when the bias voltage increases.

摘要：Plant extracts are widely studied for their anti-cancer and cancer preventive effects. In this study, we compared the leukemia growth inhibition effects of seven different plant extracts, theaflavin, epigallocatechin gallate (EGCG), epicathechin (EC), apigenin, quercetin, chrysin and tannic acid, in vitro using the K562 erythroleukemia cell line and application of the design of experiments (DoE) methodology. Our systematic approach enabled us to isolate the main factor contribution, two-factor interactions and produced interaction relationships and/or models to describe growth inhibitory effects of different plant extracts when they are used in combination. The results identified tannic acid as the most significant inhibitor in this group and had synergistic effects with EGCG at specific concentrations. The fitted model of their combined effects showed that the most potent combination is at low concentrations of tannic acid (10 - 20 μM) and high concentrations of EGCG (80 - 100 μM). We further showed that tannic acid induced both growth inhibition and apoptosis in K562 cells in ranges between 10 - 100 μM. The polyphenol caused cell cycle arrest at G2- phase under the higher concentrations. In summary, use of DoE techniques effectively identified the most prominent inducer in this group of plant bioactive compounds and produced combinatorial bioactivity of various polyphenols and flavonoids over the entire range of concentrations under study. This study exemplifies the usefulness of DoE and serves as a guide in its utility for in vitro assessment of bioactivity in plant constituents.

摘要：Eco-tourism theories were taken as the instruction in this study,qualitative and quantitative research methods were also combined to investigate and conduct questionnaire processing to nearby residents of 10 eco-tourism scenic areas in south Shaanxi Province,so as to quantify and evaluate the various effects at different levels of eco-tourism development on tourism destinations in this ***,the quantitative value and weight value of economic,social and environmental effects were utilized to quantify,analyze and evaluate the comprehensive effects generated by eco-tourism development in south Shaanxi *** was found that the comprehensive effects were 'good',however,these 3 kinds of effects have not been coordinated well,thus the characteristics and requirements of eco-tourism have not been well demonstrated.

摘要：In this paper, blocking in response surface for fitting first order model incorporating neighbour effects has been investigated. The conditions for orthogonal estimation of the parameters of the model have been obtained. A method of constructing designs which ensures the constancy of variance of the parameter estimates of the model has also been given.

摘要：After effects对于矢量处理历来是一个短柄,如果要在After effects中编辑一些矢量图形元素,就必须依靠类似llustrator矢量图制作软件来辅助。但是,After effects引入了shape Layer的概念,加之添了一些制作效果的简便手段,为设计者在后期制作中提供了有效的途径。本文以解析腾讯帝国广告动画的扁平化设计为例,引出如何灵活地运用After effects的形状图层,并对其片段动画中及CG领域是如何高效、准确的表现其动画制作优势进行说明。
