The elementary idea of the reference units method can be described as follows : firstly, by the setting of double series of reference units, we can control the highest and lowest land quality class of each village or town ; secondly, the class of the arable land will be get through the contrast between the arable land with the reference unit which has been selected in the same area, the difference in quality is the key factor to classify the land. the results show, 87. 6 % of the lands from i to iii distribute on alluvial and lacustrine plains, where the associated soils are mainly grey fulvo - aquic and calcareous concretions black ones. and 61. 4 % of them from iv to vi distribute on slightly rolling parts with mainly yellow - cinnamon soil developed from the diluvial and slope deposits
分等結果表明：臥龍區等的耕地中，有87 . 6分佈在沖積、湖積平原區，主要土壤類型是在河流沖積物上發育形成的灰潮土、在湖相沉積物上發育形成的砂姜黑土；等耕地中，有61 . 4分佈在壟崗區，主要土壤類型是洪坡積物上發育形成的黃褐土：而、等耕地集中分佈在丘陵區，主要土壤類型是殘坡積物上發育形成的粗骨性黃褐土，等別結果分佈總體上體現了不同地貌類型、土壤條件下耕地質量的差異。 -
Finally, it is pointed that individual acoustic contrast agents can be gotten with chemical method, and the double virtues of imaging and targeted therapy will be possessed
指出採用化學方法能得到更加個性化的聲學造影劑，並使其具有成像和靶向治療的雙重功效。 -
In order to study the thermal performance and residual stress of microelectronic subassembly, in this paper, a newly optical interferometry method for 3 - d displacement measurement is developed based on wavefront interference theory. in which the moire interferometry provide the in - plane displacement, but the system is different from the conventional interferometry, the system applies the double diffraction of the specimen grating, the in - plane displacement sensitivity is a factor of 2 higher than that of the conventional moire interferometer. twyman / green interferometry method for out - of - plane displacement measurement is adapted, the advantages of the optical set - up are structure novelty, and the fringe patterns of the displacement fields shown high contrast and spatial resolution
為了詳細研究試件的熱變形特徵以及殘余應力的影響作用，本文在波前干涉理論的基礎上，設計了一新型三維光學測試系統，該系統的平面位移測試基於雲紋干涉方法，但採用與普通雲紋干涉不同的光路系統，利用試件光柵和平面反射鏡組形成的兩次衍射，使平面位移干涉條紋倍增，測量靈敏度是普通雲紋干涉的2倍，系統的離面位移場測試採用泰曼格林干涉光路。 -
Firstly, the linear method is used in analyzing the finite element model of the bridge, mainly computes the stability coefficient and instability mode of the bridge, considering the constant load, the wind load and the various disadvantage load. secondly, the nonlinear stability is computed, considering the constant load to contrast the stability coefficient of the linear method with the nonlinear stability coefficient of results taking into account the geometrical nonlinearity and the double nonlinearity
在線彈性特徵值分析中，主要計算了考慮恆載、風載、以及各種不利活載作用下的穩定安全系數以及失穩模態;在考慮非線性影響的穩定分析中，只考慮了恆載，主要是來分析對比幾何非線性、雙重非線性下的穩定安全系數與特徵值穩定安全系數的差別。 -
After designing the hidden - layer structure of network, the neural network data - mending program is developed with matlab, and with the contrast of results gained from single and double hidden - layer the number of hidden - layer is selected. after the training algorithm is studied, using the visual application - designing tool, visual basic, the application adopting the designed algorithm is developed. with plenty of experimental study, the node number of the hidden - layer is decided and the rational algorithm is designed, which can advance the speed of training network, and decrease the probability of running into the local teeny value
在研究網路隱層結構后，用matlab編制了神經網路修補程序，對比單雙隱層結構的修補結果，確定了修補用bp神經網路的隱層數；在研究網路訓練演算法后，利用可視化應用程序開發工具visualbasic ，編制了相應的應用程序，通過大量的實驗研究，確定了網路隱層節點數，設計了合理的網路訓練演算法，提高了網路的訓練速度，減小了網路訓練陷入局部極小的可能性。 -
By contrast, the effect of improving the adhesive mode of cfp, that is to say, epoxy - bonding double carbon - fiber composite plates or epoxy - bonding u shape cfp anchorage is less notable. the loading - bear capacity of double cfp reinforced concrete beams is 8. 5 - 11. 3 percent higher than that of the single cfp reinforced concrete beams ; the loading - bear capacity of epoxy - boding u shape cfp anchorage reinforced beams is 4. 7 - 18 percent higher than that of the single cfp reinforced beams
相比之下，改善碳纖維板的粘結方式，即採用粘結雙層碳纖維布和在單層碳纖維布的基礎上粘結u形包頭的影響要小一些：採用雙層碳纖維布加固比單層碳纖維布加固時的極限承載力提高了8 . 5 % - 11 . 3 % ；採用包頭形式加固比單層碳纖維布加固的極限承載力提高了4 . 7 % - 18 % 。 -
2. rebuilding of the double sh ridges based on the case of double ridges during the breaking interval of plum - season rainfall in the summer of 1998, it is indicated that the sh ridge would remarkably locate much more southward than its normal position after the phenomenon of double sh ridge is over. furthermore, this southward migration of sh ridge is not sudden but results from the southward rebuilding of the double sh ridges, that is, the northern ( original ) ridge gets enfeebled and disappeared, in contrast, the southern counterpart becomes intensified enough and steadily persists
（ 2 ）副高脊線的「重建」根據98年夏季梅雨間歇期副高雙脊線個例，指出雙脊線現象結束后，副高脊線會出現顯著偏南，且這種偏南不是突發性的，而是副高脊線在南側「重建」的結果，即副高北側脊線減弱消失，南側脊線發展維持。
