  1. ( 2 ) on the leading edge, the film cooling effectiveness at the zone immediately downstream of the cooling holes is affected by blowing ratio and mainstream reynolds number, while the effects are not important in the downstream zone far from the cooling holes. ( 3 ) on the front half of pressure surface, the effectiveness increases with decreasing blowing ratio at the downstream near the cooling row and it is contrary at the downstream far from the cooling row. ( 4 ) on the rear pare of the pressure surface, the effectiveness decreases with increasing blowing ratio and does not vary so much downstream in the cases of higher blowing ratio

    研究結果表明葉片吸力面端壁附近區域壓力系數分佈呈現出較強的三維特性，動葉吸力面尤其明顯；氣膜孔流量系數隨吹風比的增加而增大，在高吹風比情況下，流量系數逐漸趨于常數；在不同型面區域，冷卻效率分佈有較大的差異，而且吹風比與主流雷諾數的影響程度也不盡相同；低吹風比下，孔出口下游附近可以得到較好的冷卻，中、高吹風比下，冷氣射流在加速流動主流的作用下返回壁面進行二次冷卻，孔下游較遠區域可以得到較好的冷氣覆蓋。
  2. Asymptotic mean unavailability

    漸近平均不可用度
  3. But in more situations the random variables generating counting processes may not independent identically distributed, and in all kinds of dependent relations, negative association ( na ) and positive association ( pa ) are commonly seen. the research and apply in this aspect are rather valuable. in chap 2 we prove wald inequalities and fundamental renewal theorems of renewal counting processes generated by na sequences and pa sequences ; in chap 3 we are enlightened by cheng and wang [ 8 ], extend some results in gut and steinebach [ 7 ], obtain the precise asymptotics for renewal counting processes and depict the convergence rate and limit value of renewal counting processes precisely ; at last, in the study of na sequences, su, zhao and wang ( 1996 ) [ 9 ], lin ( 1997 ) [ 10 ] have proved the weak convergence for partial sums of stong stationary na sequences. however product sums are the generalization of partial sums and also the special condition of more general u - statistic

    但在更多的場合中，構成計數過程的隨機變量未必相互獨立，而在各種相依關系中，負相協（ na ）和正相協（ pa ）是頗為常見的關系，這方面的研究和應用也是頗有價值的，本文的第二章證明了na列和pa列構成的更新計數過程的wald不等式和基本更新定理的一些初步結果；本文的第三章則是受到cheng和wang [ 8 ]的啟發，推廣了gut和steinebach [ 7 ] ）中的一些結論，從而得到了更新計數過程在一般吸引場下的精緻漸近性，對更新計數過程的收斂速度及極限狀態進行精緻的刻畫；最後，在有關na列的研究中，蘇淳，趙林成和王岳寶（ 1996 ） 》 [ 9 ] ，林正炎（ 1997 ） [ 10 ]已經證明了強平穩na列的部分和過程的弱收斂性，而乘積和是部分和的一般化，也是更一般的u統計量的特況，它與部分和有許多密切的聯系又有一些實質性的區別，因此，本文的第四章就將討論強平穩na列的乘積和過程的弱收斂性，因為計數過程也是一種部分和，也可以構成乘積和，這個結果為研究計數過程的弱收斂性作了一些準備。
  4. Having received the support of the industry, the hard work and care wheel giant has invested in tbs has won the endorsement and backing of tbea taiwan bicycle exporters association. tbea supervise the content and issuance of tbs, and lend support in the form of its resources and distribution channels. with an added boost from wheel giant s extensive marketing network established over many years, its active trade show presence, and outstanding relationships with foreign trade magazines, tbs is certainly the best and the biggest advertising vehicle for the industry

    近年來自行車產品不論在外觀設計或材質搭配上，儼然進入輕量化與個性化的白熱時期，仔細觀察各大品牌所推出的年度新車，便可看出端倪，自行車的設計趨勢包括：碳纖維材質的運用更廣泛，在成型技術上也逐漸朝整合一體成型monoque與管對管tube to tube的技術發展此外，車架的幾何角度也有所改變：頭管角度較平緩豎管較短而車架的系統整合設計也是一大趨勢。
  5. In order to obtain an optimal estimate of the tilt angle and angle velocity, an indirect kalman filter configuration combining a rate gyroscope sensor and an accelerometer is implemented. because of the extreme nonlinearity of the two - wheeled self - balancing robot, application feasibility of nonlinear system control strategy based on linear approximation method, exact linearization and intelligent control have been investigated. according to robustness, balancing performance and environment adaptability, robust tracking control, linear quadratic regulator and fuzzy model reference learning control are implemented to the velocity controller

    針對具有強非線性的前進子系統，論證了基於近似線性化、精確線性化及智能控制的非線性系統控制策略的應用可行性，據此按照不同性能要求設計了三種前進速度控制器:漸近跟蹤魯棒調節器簡單精確，具有良好的干擾抑制能力;二次型最優跟蹤控制器，在耗能最小的條件下，大大提高系統的平衡能力;而基於動態聚焦學習的模糊模型參考學習控制則兼具平衡性能好、環境適應性強、精度高及魯棒性好的優點。
