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.     

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.     

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.

燕麦饲草多组分营养差异分析

为挖掘利用高营养燕麦饲草种质资源,将源自以色列不同地区的23份野生燕麦生态型和3份燕麦栽培品种种植于四川甘孜、贵州贵阳、四川成都3个环境,分别在抽穗期、灌浆期、成熟期进行刈割处理,并测定其酸性洗涤纤维(ADF)、中性洗涤纤维(NDF)、酸性洗涤木质素(ADL)、纤维素(F)、半纤维素(HF)、木质素(L)、洗涤纤维中性...     

栀子叶斑病及其病原的鉴定

首次报道在栀子(Gardenia jasminoides)上存在由拟盘多毛孢属真菌引致的叶斑病。从湖北省长阳县采集到栀子叶斑病病害标本,并利用柯赫氏法则证实该病由真菌GJ-1菌株所引致;根据GJ-1菌株的形态学特征和ITS序列的分析、比较,证实GJ-1菌株属于拟盘多毛孢属(PestalotiopsisSteyaert)真菌;GJ-1菌株的ITS序列与P.gracilis的ITS同源性达100%,因此推定它属于P.gracilis。     

大豆作为前作植物对油菜根肿病发生的影响

为了解前作大豆对后茬油菜根肿病的影响,采用大田轮作试验和实时荧光定量PCR检测法,研究大豆、白菜、油菜分别作为前作,调查后茬油菜根肿病的发生和土壤中休眠孢子含量,比较分析了不同前作的根系分泌物对休眠孢子萌发的影响,结果表明前作大豆,后茬油菜根肿病的发病率和病情指数分别为34.00%和19.26、土壤休眠孢子含量为1.45×106个/克土壤,显著低于前作为油菜、白菜和撂荒对照的相应量。大豆、油菜和白菜根系分泌物均可刺激根肿菌休眠孢子萌发。与根肿菌休眠孢子共培6 d后,大豆根系分泌物培养的休眠孢子萌发率为29.82%,显著高于白菜（15.52%）、油菜根系分泌物（14.83%）和营养液（6.48%）培养下的萌发率。据此推测,前作种植大豆,后茬油菜根肿病发生和危害减轻,原因应与大豆根系分泌物刺激根肿菌休眠孢子萌发,产生的游动孢子因缺少寄主植物而死亡,导致诱发病害的初侵染源（土壤中休眠孢子含量）减少有关。
