中药“增免散”对免疫抑制鸡免疫功能的影响

将300只1日龄雏鸡随机分成正常对照组、中药“增免散”组、环磷酰胺组、环磷酰胺组 左旋咪唑组、环磷酰胺 “增免散”组,6日龄用鸡新城疫LaSota疫苗免疫点眼滴鼻,14、21、28、35日龄测定鸡血液ND抗体效价、免疫器官指数、细胞免疫功能、红细胞免疫粘附功能等,探索中药“增免散”的免疫增强机理。结果表明:中药“增免散”不但能显著提高Lasota活苗接种雏鸡的特异性HI抗体水平,延长其持续时间,能促进雏鸡免疫器官的生长发育,能显著增高雏鸡外周血T淋巴细胞ANAE阳性率,并对雏鸡红细胞免疫粘附功能具有显著促进作用,而且对环磷酰胺的免疫抑制有部分拮抗作用。     

不同花生品种侧枝发育动态与产量性状研究

花生一级侧枝发育具有不均衡性。第一、二对侧枝出现早，伸长快，其他一级侧枝出现晚，伸长慢。86036－26－1第一、二对侧枝发育相对较早，而其他一级侧枝发育较晚；海花1号和豫花1号第一、二对发育相对较晚，而其他一级发育较快；豫花7号和鲁花9号居中。海花1号一级侧枝及第一对侧枝的二级侧枝数最多，86036－26－1的一级侧枝数及第一对侧枝的二级侧枝数量少。在花针期之前第一对侧枝的伸长与主茎基本同步；花针期之后，第一对侧枝伸长速度超过主茎。86036－26－1的一级侧枝长及株高居首位。86036－26－1第一、二对侧枝饱果率，产量居第一，豫花7号居第二。海花1号虽然荚果数较多，但第一、二对侧枝孢果率较低，产量也较低；鲁花9号居中。     

Research on Relationship between the Level of Urbanization and the Growth of Real Estate Investment

The population proportion index is usually introduced to measure the level of urbanization, which is an important index to the national economy. The fast development of urbanization would inevitably cause the increase of the investment in real estate industry. Introducing the Granger Test of Causality analytical method, in this paper the relationship between the level of urbanization and the investment in real estate industry from 1986 to 2003 in China is analyzed. It reveals that both of them are on the stage of constant up - rising, and the correlation index of 0. 205 shows that the relationship between them is a mutual promoting causality.     

遵循市场规律 迎接新的挑战

新世纪我们的农业要走向世界市场 ,重点可从两个方面做出努力 ,一是提高农产品质量 ,使之与国际质量标准接轨 ;二是遵循市场供求规律 ,不断调整种植结构。要做好这两方面工作 ,都离不开“种子”这个重心。我国《种子法》的贯彻实施 ,无疑将对加速良种的研究创新、种子生产经营和成果转化产生巨大推动作用。市场农业拉动种业发展 ,种业的发展反过来又推动农业向更高层次迈进。这样的发展趋势 ,对县级国有种子公司来说是个良好机遇。但是《种子法》立足于保护市场运作规则 ,国有种子经营将失去垄断地位。从这点意义上说《种子法》的实施 ,将使…     

Biodegradation of Linear Alkyl Benzene Sulphonate

The paper researches on the degradation of LAS (Linear Alkyl benzene Sulphonate) by combining AS1.860 immobilized with low intensity ultrasonic irradiation. The paper also discusses the influence of pH, rotary velocity, LAS concentration and the condition of low intensity ultrasonic irradiation on the degradation of LAS, the degradation rate of LAS is the main index of our experiment, the results of orthogonal test shows that low ultrasonic irradiation can increase the metabolizing of microorganism cells and facilitate the biodegradation of immobilized cells to LAS, here we research the degradation condition of 50mg/L LAS simulation wastewater with low ultrasonic irradiation, and the results show that the influence is obvious, the optimization degradation rate is about 83%, nine point five percent higher than that of the immobilized cells without ultrasonic irradiation.     

The Bankruptcy System and the Auction Model of Management Buyout

This paper studied how the auction processis influenced by bankruptcy probability, bankruptcy cost, and the corporatetax rate. The study found thatthe bidding price of the management is negatively associated with bankruptcy cost and probability, and positivelyassociated with the corporate tax. However, the expected profit of the outside investor is positivelyassociated with bankruptcy cost and probability, and negatively associated with the corporate tax. When the bankruptcy cost and probabilityis high enough, the acquisition market would be totally inefficient.     

Deciding Method of Capability Vs. Price of Real Estate

The authors determine the index system and the index weight of capability of real estate by applying Delphi method and AHP method, and found the fuzzy comprehensive evaluation model of capability of real estate. They creates the model of capability Vs. price based on value engineering theory. The authors analysis detailedly deciding method of capability Vs. price of real estate combined with a practice example and application. The method adapts to a house as well as the type of the house. The method resolves the problem which capability Vs. price of real estate was only described by qualitatively for ages, which supplies theory basis to developer and consumer.     

Filtering Construct of Adaptive Filter Grou Pwith Multi-scale Decomposition

The principle and method of the adaptive filter and the filtering with wavelet transform were analyzed, and the model and method of adaptive filtering with wavelet transforms for the transient signal was established. The separated noise of signal by the multi-scale decomposition of wavelet transforms, was the input signal of adaptive filter, and accordingly the optimal filtering method of signal-noise decomposition was realized. By the adaptive filter grou Pbased on the wavelet transform, the optimal filtering to the multi-noise of signal is achieved at the same time, and the method presented in this paper has the excellent filtering capability. Examples of application demonstrate that this method presented is excellent to realize the optimal estimate to the valuable signal and noise of the transient signal in the same frequency segment.     

Real Estate Brand Evaluation

At present, in the evaluation process of the real estate value the material form is mainly concentrated on, while the value brought by the real estate brand are usually neglected. In this paper, considering the particularity of the real estate brand evaluation, the method of network analysis is adopted. In the evaluation process, the evaluation method of excess income law are developed by leading the thoughts and methods of the fuzzy set theory, and a systematic assess model is found. Then, an example is given as illustration. At last, the appraise about the application of the model is made.
