baotou City is an industrial city developed in the farming-grazing transitional zone in northern China. The development of industry, farming and grazing is very fast. It has become a typical intergrated economic region of industry, farming and grazing. Based on the analysis of utilization of land resources, this paper points out the main conflicts and problems on the utilization of land resources in the city, and puts forward a corresponding proposal.

On the basis of grey correlation analysis,8 factors impacting grain production prominently as follows are selected to establish indices system:yield per unit(X1),grain planting area(X2),agricultural labor forces(X3),the total power of agricultural machinery(X4),using amount of fertilizer(X5),the damaged area of crops(X6),effective irrigation area(X7),and agricultural fixed assets investment(X8).According to the relevant data of Inner Mongolia Statistical Yearbook from 1988 to 2008,we use the method of grey correlation analysis to analyze the factors impacting grain production in Inner Mongolia,quantify the correlation degree of the total grain output and all factors,and finally conclude the impacting capacity of all factors on grain production in the light of correlation degree *** results show that yield per unit still is the principal factor impacting the total output of grain in Inner Mongolia;the area of grain planting and the area of affected crops are the two most important factors responsible for the decrease of grain output;effective irrigation area the total power of agricultural machinery are the two primary factors impacting the increase of grain output;the using amount of fertilizer shows dwindling impact on grain production;agricultural fixed assets investment still hovers at the minuscule impact degree on grain production.

OBJECTIVE To investigate the significance of angiogenesis of lung cancer, in order to provide a scientific basis for interventional therapy. METHODS Double-phase enhancementscanning spiral CT and DSA were performed in 56 pathologically confi rmed lung cancer cases, in order to evaluate angiogenesis of the tumors. The patients included 36 males and 20 females, with ages ranging from 33 to 76 years (average of 53). Assessments and indexes for SCT and DSA examinations were as follows: a) Peak value (PV) of the cancerous focus was the difference between the maximum CT value after enhancement and the CT value of a plain scan; b) The abnormally distorted and expanded new vessels of the cancerous focus which could be macroscopically discriminated; c) DSA staining of the focus of cancer was sparse, grid-like and dense. Chemotherapy and embolotherapy via the bronchial artery (interventional therapy) were conducted. Radiotherapy was added for some of the solid tumors with a diameter exceeding 4 cm. RESULTS a) There were 25 cases with a central-type lesion, among which 4 were small cell lung cancers (SCLC) and 21 non-small cell lung cancers (NSCLC). The cases with a peripheral location accounted for 31 of the total, with a maximum diameter of 1.5 to 13.5 cm and a median of 4.2 cm, including 5 small cell lung cancers and 26 NSCLC cases. b) The reinforced PVs of the cancerous foci were as follows: The PV ranged from 45 to 70 Hu in 34 cases, 25 to 45 Hu in 19, and 10 to 25 Hu in 3. Sparse DSA staining occurred in 3 cases, there was uneven grid-like staining in 22 and dense staining in 31; c) The interventional therapy via the bronchial artery was con-ducted twice in 5 cases with the SCLC, and three times in 4 SCLC cases. For 3 of the latter cases, a dose of 5,000 to 7,000 cGy radiation therapy was added during the interventional treatment. Complete remissions (CR) were seen in 88.9% of the cases (8/9) and partial remission (PR) in 11.1% (1/9). Interventional therapy was conducted

周代交聘礼中的对等性原则

对等性是周代交聘礼中的重要原则,是中国古代发展政治实体、政权、民族、乃至国家之间和平交往关系的重要准则和宝贵的政治思想财富。其对等性原则主要体现在:一是交聘主体的对等性。《仪礼.聘礼》和周之《秩官》所载典型的交聘关系,其交聘主体是两个对等诸侯国及其国君。二是接待人员的对等性。如果聘国以卿、大夫、士组成使团,则主国亦设置与此级别一一相对应的接待官员组合以负责接待事宜。三是接待仪节的对等性。交聘礼仪中宾主双方在服饰、进退揖让和面向等具体仪节均一一对等均衡,贯穿于聘礼的全过程。对等性原则在周代产生并非偶然,一方面,周代分封制度所贯穿的等级秩序,为交往关系中等级性的敌体、对等关系提供了"法理"上、制度上和事实上的依据。另一方面,对于"礼"的辩证思维和"中"、"和"、"德"等理念与对称、平衡的文化意蕴则是聘礼中对等性原则产生的理论基础和文化依据。周代交聘礼中的对等性原则不仅在日后汉唐时期的交聘制度中有所继承、借鉴,而且与近现代国际关系中的对等性原则亦有相似、相通之处。
