沉降率單位
英文
unit sedimentation rate-
Firstly, the theory of compound foundation and pile foundation are summarized in this paper. the finite element, displacement models and computational program are introduced, then how such factors as the stiffness of pile, the ratio of length and radius of the pile & replacement ratio influence the settlement of compound foundation are analyzed. there has the best modulus of pile, the best of the length & replacement ratio and some data have been obtained
首先總結了復合地基和樁基的理論和設計計算方法，對有限單元和位移模式以及有限元計算程序進行了介紹，然後分析了樁的剛度、長徑比、置換率等因素對復合地基沉降的影響，證實了帶承臺復合地基存在最佳樁土模量比、最佳長徑比和最佳置換率，並得出了相應的數值可供工程實踐參考。This paper has discussed preparing diamond - like carbon films by means of micro - wave ecr plasma source ion implantation and plasma enhanced chemical vapour deposition. we use the raman spectrum, ft - ir, afm and so on to study the dlc film. the result indicates : different bias voltage, frequency and gas flow rate of psii will have impact on sp3 proportion of dlc films, we find high bias voltage, low frequency and moderate gas flow rate can prepare high sp3 proportion dlc films ; we simply illustrate the influence of bias voltage on sp3 proportion of dlc films in pecvd
研究結果表明：在全方位離子注入技術中，不同的偏壓、頻率、氣體流量都對薄膜中sp ~ 3鍵比例有所影響，文中對具體的影響進行了分析，發現偏壓的增加、頻率的降低和適中的氣體流量可以制備出sp ~ 3鍵比例高的類金剛石膜；在等離子增強化學氣相沉積技術中，對偏壓對sp ~ 3鍵比例的影響也進行了簡單分析。
