They are jinfo mountain in nanchuan county ( natural protection section ), wuling mountain in qianjiang county ( national emphases forest demonstration county which forest cover rate is beyond 50 % ) and zhongliang mountain in beibei county ( artificial destruction is very grave ). some main land use patterns i. e. woodland, garden, infield, abandon infield, shrub and grassplot are selected in those three sample sites. four aspects on soil fertility index of karst environment under different land use patterns in these three sample sites, are revealed in this paper, by using the field test, indoor measure and analysis, outdoor experiment and field investigation, and the knowledge and technique of soil, ecology, physics and chemistry etc. they are physical characteristic ( effective soil thickness, organic layer thickness, soil texture, water - stable aggregate and soil water etc. ), chemical fertility ( organism, omni - n, omni - p, omni - k, alkali - nitrogen, available p, available k and rapid available k etc. ), soil animalcule ( bacteria, fungi, actinomyces and their grosses ) and soil - seed - pool ( plant community diversity index ) in karst ecosystem
本研究以重慶市的南川金佛山（自然保護區） 、黔江武陵山（國家重點退耕還林示範縣，森林覆蓋率50以上）和北碚中梁山（遭人為破壞嚴重）典型巖溶區為對象，選擇了幾種重要的利用方式，包括林地、果園、耕地、棄耕地和灌草坡，採用野外巖溶生態調查和室內試驗測量分析相結合的方法，以不同土地利用方式巖溶土壤肥力為重點，對不同土地利用方式土壤肥力特徵進行量化分析，找出巖溶土壤肥力差異的主要方面及其根本原因，論文主要從土壤剖面物理退化指標（有效土層厚度、有機質層厚度、質地、團聚體、水分含量等） ，化學肥力退化指標（有機質、全n 、全p 、全k 、堿解n 、速效p和速效k等） ，樣地土壤微生物指標（細菌、真菌、放線菌數量及總量）以及樣地土壤種子庫植物群落多樣性等4個方面對重慶典型巖溶區的土壤肥力特徵進行了較為詳細的分析研究，為巖溶地區士壤資源的合理利用及結構的調控管理提供依據。 -
Alkali recovery is an effective way dealing with the black - liquor in pulp mill. black - liquor evaporation and combustion in, alkali recovery are complicated industrial processes. they have characteristics such as strong coupling, non - linearity, large time delay, parameter examining difficulty, etc. and people require more effective control system for the processes "
堿回收是紙廠處理黑液的有效方法，造紙堿回收過程中的燃燒和蒸發工段是復雜的工業過程，具有復雜性、非線性、大時滯和參數檢測困難等特點，而且人們對于控制系統的控制性能也提出越來越高的要求，常規控制技術已經沒有辦法滿足生產的需要。 -

竹子硫酸鹽法間歇蒸煮過程有效堿濃度數學模型研究 -
The study reveals that the infected soil is of high ph value and low effective iron content and the afore - said infected trees and plants suffer from a deficiency of iron for their normal growth, as the alkali soil is lack of effective iron, and the insufficiency in turn weakens the rhizome of the trees to absorb iron effectively and impedes the movement of iron along the trunk and branches
結果表明：舟山市朱家尖苗木基地紅楠黃化是由於基地土壤呈堿性，致使土壤中缺少有效態鐵，影響了根系對鐵的吸收和鐵在樹體內的移動及有效性，不能滿足紅楠正常生長對鐵的需要而引起的缺綠黃化癥。 -
In the other hand, fbg is fragile and subject to attacks of acid and alkali. as a result, it is necessary look for effective packaging methods to protect fbg for fixing and making a stand against the rough environments. in this work, experimental results on packaging of fbg are presented
另一方面，由於光纖光柵是紫外光在去掉塗覆層的單模石英光纖上寫入，質地脆，容易折斷，抗酸、堿能力都較差，在實際應用中，為了便於安裝和抵抗惡劣的環境，因此也必須尋找有效的封裝方式，對光纖光柵進行保護。
