居民收入与通信网络市场经济效益研究--以河北省通信网络为实例

利用Logisitic曲线模型和扩展支撑模型对居民可支配收入预测和单项消费预测，以河北省居民的收入及其消费支出为实例，研究了城镇居民和农民的可支配收入分配和单项边际消费倾向，合理建立了预测模型，并理论计算了1999～2003年的通信消费方面的边际消费倾向、预测了2004～2008年通信消费情况。最后，根据预测结果对通信网络建设提出了一些有价值的建议。     

Infrared Study of T Tauri Stars Based on IRAS and 2MASS Observations

The IRAS and 2MASS associations for 193 T Tauri stars are identified in this paper. From the color–color diagrams and spectral index, it is found that the IR excesses for most samples are due to thermal emission from the circumstellar material, as suggested previously. It is also found that the IR excesses at IRAS region for few T Tauri stars and the near-IR excesses for some T Tauri stars are likely attributed to free-free emission or free-bound emission from the circumstellar ionized gas. Moreover, It is found in deredened J–H versus H–K color–color diagram that there is a slight separation in different spectral groups. The T Tauri stars locus equation in J–H versus H–K color–color diagram for our sample is also presented.

A possible mechanism of formation of faculae

We propose a new heating mechanism of faculae. We think that the formation of faculae is a result of the Joule dissipation of the Hall current generated by the interaction of the convection field of granules in an active region and the inter-granular magnetic field. For a region to generate effectively Hall current, its characteristic length must be such that the magnetic Reynolds number is less than 1. The equation of energy balance in the facula region is

$\text{16σT}{}^3{}_{\mathrm{p}}\text{(T}{}_{\mathrm{l}}\text{? T}{}_{\mathrm{p}}\text{)}{}^{\mathrm{n}}\text{HP}{}_{\mathrm{s}}{}^{\mathrm{a}}\text{H}{}^{\mathrm{?}}\text{=}\text{Qn}{}_{\mathrm{s}}\text{m}{}_{\mathrm{i}}\text{u}{}_{\mathrm{x}}{}^2\text{(τ}{}^2{}_{\mathrm{in}}\text{ω}{}_{\mathrm{i}}\text{)}$

.For five observational models of faculae, we calculated the corresponding velocity fields, and the results are in basic agreement with the observed fields. The present mechanism explains the dependence of the facula brightness on the magnetic and velocity fields, the apparent distribution of the faculae on the solar disk and suggest a possible interpretation of the five structures of faculae.     

海洋钢筋混凝土结构牺牲阳极保护系统电极行为的研究

于１９８９－１９９０年在室内条件下，用牺牲阳极保护浸泡于海水中的多种钢筋凝土试件测试不同试件中钢筋极化与阳极布局、涂层质量，涂层厚度及试件浸水情况的关系。结果表明，牺牲阳极能有效地保护全浸海水中的混凝土试件，对间断浸淋海水的试件也有一定的保护作用，通过改善阳极安装工艺，保护作用可望提高；电偶电流在各阴阳极上的分布将随涂层质量，涂层厚度和试件浸水情况不同而异，回路中电阻和电极极化情况是影响电流分布的

The paper introduces the conclusion of tests and the dynamic properties of single-column platform are obtained.     

鱼类消化道细菌及其作用研究Ⅱ.鲻鱼

本文报道了从鲻鱼消化道分离的好气性异养细菌数量为（1．5×108±0．4×108～6.4×108±2.0×108）个／g，共分离220株细菌。其种群组成为弧菌、气单胞菌、不动细菌、假单胞菌、微球菌、黄杆菌、葡萄糖细菌、纤维单胞菌、节细菌和棒状杆菌。测定其生化特性，表明该类菌对有机质的分解能力比较强，这些特性有利于鱼类对营养物质的消化和吸收，并进一步促进其生长和发育。     

海南东寨港红树林港湾潮汐动力研究

在海南东寨港林市村附近红树林港湾潮汐动力测量的基础上，建立二维可移动边界有限元数值模型，研究红树林港湾浅水湖滩潮流场特征。实测与计算结果表明，潮沟区流速最大，具驻波特征，呈明显时间－速度不对称，东潮沟涨潮优势，百潮沟落潮优势，整个港湾水体呈顺时针循环。白滩与林地周期性淹没，白滩流速较湖沟略小。林地曼宁系数为白滩的１０倍，流速小于１０ｃｍ·ｓ（－１），约为相应潮沟流速的１／１０。林地如去掉林木，流速可增加３倍以上，流向也有变化。
