With the steady growth of natural gas, the recent hot spot of world sources of energy and with the encouraging progress in such renewable sources of energy as solar energy and wind energy, the proportion of oil in the world ' s unrenewable sources of energy has indeed been lower than before ; nevertheless, upon comparing with natural gas, nuclear energy and other sources of energy, it has been found out that the dominance of oil in the world ' s unrenewable sources of energy will remain unshakable in the coming 20 years though after that period of time there may be intense competition between oil and natural gas for supremacy. although people have been repeatedly made a fool of by the unpredictable oil price and made one misjudgement about it after another, yet given the world general situation of oil supply and demand, the essential variable, with which the oil price will continue to vary, plus other factors, such as the oil price policy of some middle eastern oil producers which is tending more and more rational, it can be roughly concluded that the world oil price will be stable with a slight rise
再者，隨著天然氣? ?世界能源的新熱點的「蒸蒸日上」 ，在太陽能、風能等可再生能源方面取得的可喜進展，石油在世界一次能源構成中的比例的確已不如往昔，不過，一經與天然氣、核能等進行對比分析，就發現石油在世界一次能源構成中的「霸主」地位在今後20年內仍難撼動，此後有可能會出現天然氣與石油一決高低的局面；在難以捉摸的油價面前，人們曾一次次地受到它的捉弄，一次又一次在它面前「失算」 ，但基於世界石油供求大勢仍將是其變動的基準，再考慮到其他因素，諸如中東產中東石油與21世紀的中國石油女全內容摘要油國的漸趨理性的油價政策等的影響，大致可以得出世界油價穩中有升的結論，當然，由於世界石油市場的本性使然，加上新近出現的加劇市場動蕩的4大不穩定因素的干擾… …油價在未來一段時間內依然難改動蕩本色。 -
The electrode classification shall be shown in the welding procedure specification ( wps ) and shall be considered an essential welding variable
焊接工藝規程中應註明焊條類別，並將其視作一重要焊接變素。 -
The cointegration analysis of the impacts of the import, export and per capita income on the industrial structure from 1978 to 2004 in yunnan province has reached the following results : there exists one cointegration relation between the four variables ; export has a positive impact on the upgrading of the industrial structure while import has a negative impact ; per capita income has little impact ; the " essential variable " of the development of industrial structure is on the increase
雲南省1978 ~ 2004年出口、進口及人均收入對產業結構的促進作用的協整分析表明：四個變量之間存在惟一的協整關系，出口對產業結構升級有正相關作用，進口則阻礙產業結構升級，而人均收入對產業結構的影響不明顯，產業結構成長的「本質變量」逐漸增大。 -
At the n - terminal end is the variable domain of 26 amino acids in length, which has no conserved mgxxc ( s / q ) xxt sequence essential for n - myristoylation. so it is conferred that the vfcpkl is a soluble protein
N端的可變區有26個氨基酸殘基，沒有豆蔻酰化所必需的保守序列mgxxc （ s q ） xxt ，因此推測vfcpk1可能是水溶性蛋白。 -
Second, engine ' s partial velocity characteristics model and universal characteristics model are built the throttle opening is considered as an essential factor to build the model for reflecting the actual working performance of engine. the situation of the throttle opening change is studied, and a simulation method is given to use torque curved surface and vehicle dynamics equation on base of differential approach method. engine test software is developed for the engine no - load test, variable throttle opening test and throttle step change test
其次，建立了發動機的部分速度特性模型和萬有特性模型；為了更好的反映發動機的實際工作特性，將油門開度作為一個重要參數參與建模，並對發動機變油門的情況進行了研究；結合轉矩曲面和整車動力學方程，採用微區間逼近法確定了發動機變油門過程模擬方法；開發了發動機試驗測控軟體，利用該軟體進行了發動機空載響應試驗、發動機不同油門開度試驗和油門階躍變化試驗，並對實際試驗數據和數學模型計算數據進行對比；在vc + +平臺上開發了發動機特性模擬模塊，在系統中用軟體實現了變油門控制發動機特性的功能。 -
The second chapter reviews relevant literatures of leadership, team dynamics, collective entrepreneurship and innovation, based on which the relation models in fifth chapter are set up. first, i point out that it is essential to integrate both leadership influences and team dynamics, regard collective entrepreneurship as the focal collective performance variable. second, i think that it is essential to integrate both collective entrepreneurship influences and the innovation, regard businesses performance as the focal variable
根據理論的思路，本章分別從（ 1 ）集體創新； （ 2 ）領導； （ 3 ）員工的動態； （ 4 ）革新這些問題入手，對前人的研究進行回顧和討論，指出有必要形成系統的集體創新理論；並指出有必要把領導行為、團隊動態、集體創新能力整合起來，去探討如何形成集體創新能力；指出有必要將集體創新能力、革新率、企業績效整合起來，去探討集體創新能力是形成小企業持續競爭優勢的一個源泉。
