The causes of devolution, desertation, salinization and solonization were analysed in two aspects : it is apparently due to overpopulation, overstocking, unreasonably using, lacking of new technique, frequent occurrence of nature disaster, small area and low output of artificial pasture and semi - artificial pasture, but the more deeply reason was that the function of grassland was not completely understood only emphasizing the economic efficiency and regrowthful resource in grassland while the ecological efficiency and its potential use were neglected
本文主要從兩方面對草原三化進行了分析，首先從表面上看有以下幾方面原因，人口多、牲畜數量多、草原利用不合理、新技術推廣差、草原自然災害頻繁、人工半人工草地少產量低。其次又挖掘了草原退化的深層原因，第一對草原資源的功能和作用的認識具有片面性，只重視草原的經濟效益，卻忽略了它的生態效益；只重視草原資源的再生性，卻忽略了它的適宜可利用性。Abstract : based on the ahievement of epitaxial growth in several perovskite oxide films, we discuss the importance of substrate temperature ( ts ) and substrate material in the epitaxial growth of perovskite oxide thin films. influences of ts on growth orientation and epitaxial threshold temperature were observed. the results indicate that during the growth of the oxide films the phase formation and growth dynamics should be taken into consideration. the threshold temperature for epitaxial growth depends on the substrate materials. this demonstrates the influence of substrate material on the initial nucleation and epitaxial growth
文摘:在成功地外延生長超導、鐵電、鐵磁等多種性質的鈣鈦礦結構氧化物薄膜的基礎上，討論影響氧化物薄膜外延生長的一些因素.考慮到相形成和薄膜生長動力學，在利用脈沖激光淀積法外延生長氧化物薄膜中襯底溫度是十分重要的工藝參數.襯底溫度對成相和生長薄膜的取向都有影響.考慮到薄膜是首先在襯底表面成核、成相併生長.因此襯底材料晶格的影響是不容忽視的.觀察到襯底材料對薄膜外延生長溫度的影響.在適當的工藝條件下，利用低溫三步法工藝制備得到有很強織構的外延薄膜.這突出表明界面層的相互作用對鈣鈦礦結構薄膜的取向有著相當大的影響Apparent formation factor
視地層因數Based on the super capability of gis, the paper discusses problems on layer management of related data, design of attribute tables, and data coding etc. the coefficient of the soil liquefaction resistance k and the coefficient of soil liquefaction hazard h are presented. the seismic sand liquefaction forecasting, liquefaction disasters forecasting, and prevention measures on liquefaction are also discussed. using the software of mapgis, the process of liquefaction database setup has been studied
本文基於gis在數據存儲管理及可視化方面的強大功能，研究了適合gis環境的液化評價相關數據的分層管理，屬性數據表設計以及圖元編碼等問題；並提出了土層抗液化指數k及砂土液化災害指數h兩個重要液化評價因子，在此基礎上進一步研究了地震砂土液化預測、液化災害預測以及防治處理信息系統建設等問題。The current situation of the human resource in the area of northwest of china and the cause of its formation. when the quantity of the human resource, its culture quality and the efficiency of its use, as well as its condition of being distributed in different industries is analyzed, the typical characteristic of the human resource in the area of northwest of china has been discovered in the following : ( 1 ) the human resource is rich in quantity and has a higherich in quantity and has a higher ; ( 2 ) its labour force has a lower quality, and the resources about science, technology and education are inequality in this area ; ( 3 ) the problem of being short of talented people is serious ; ( 4 ) the talented people now available is inequality in different industry, and the labour force mainly depends on their physical strength, and then, the cause for this phenomenon has been discovered in the following : ( 1 ) because of the local population policy, the population in this area increased rapidly ; ( 2 ) the backward economy impacts the human resource on its education and employment level ; ( 3 ) for its poor natural conditions, a closed and backward idea is formed in some peasants and herdsman ; ( 4 ) the lack of the mechanism of encouraging competition in personnel policy and scientific research field resulted in the loss of the vast number of talented people and inefficient in its use
西北地區人力資源開發現狀表現為：人力資源數量豐富，其中少數民族人口比例較高；人力資源文化素質水平較低；對現有人才資源使用效率不高；人力資源在產業間分佈不平衡，就業層次較低。造成問題的原因有：少數民族的人口政策是造成西北地區人力資源數量增長過快的重要原因；經濟發展水平制約了人力資源受教育的程度和就業層次；閉塞的自然環境，使人們難以突破封閉、陳舊的觀念；人事管理制度缺乏競爭、激勵機制，造成了人力資源使用效率不高。經過了理論分析和現狀調查之後，得出了人力資源開發的理性思考，即充分認識人力資源開發的戰略意義；發展教育是人力資源開發的前提條件；人力資源開發過程中要高度重視人才引進戰略的實施；人力資源開發要從本國（或本地區）實際出發，突出特色。分享友人
