層錯襯度-
Because of no limitation to task granularity, ppa is especially suitable for scheduling fine granularity tasks ( also suitable for coarse and medium tasks of course ), consequently helpful theoretically and practically for studying task schedule algorithm for rtdcs. according to the principle of fault - tolerant scheduling, combined with characteristics of tft in rtdcs, the paper puts forward the scheduling model of tft, corresponding implementation mechanism and the dynamic fault - tolerant scheduling algorithm ( namely ftpb ) and analyzes its complexity, with experimental data and contrast table compared with other analogic algorithm

By the result of these experiments, acoustic emission ( ae ) was chosen to use in the research. at the same time, we analyse the phenomenon of acoustic emission at the base of theory, the characteristic signal of acoustic emission which comes from the faulty bearing at the angle of application, and the expression of the characteristic signal. contrast was also made on the data achieved separately from vibrational signal and ae signal, and it is proved that ae is feasible and available to the diagnosis to the fault of the rolling bearing
主要工作有如下幾方面：對本段前期實驗室階段採用的振動法幅值域無量綱處理進行了分析，並研製了現場所使用的滾動軸承故障檢測裝置，將無量綱參數診斷法應用於段修現場，且做了大量試驗；對于現場試驗中所出現的問題進行了分析，提出將聲發射的方法用於軸承的在線故障診斷；從理論上分析了聲發射現象，從應用的角度分析故障軸承的聲發射信號的特徵以及聲發射信號特徵的表示方法，並在實驗室中，採用振動法和聲發射法實時檢測的實驗數據進行了對比和分析，證明了使用聲發射法對軸承故障檢測的可行性和有效性。 -

In respect of product liability attributing principle, u. s. and many other countries establish strict liability attributing principles and improve and develop those principles with economic and technological development. in contrast our country abopt faultfree attributing principle toward manufacturers and fault attributing principle toward selles which is unfair to manufacturers an d not good to consumers " rights protection
在產品責任歸責原則方面，美國等國家大部分確立了嚴格責任歸責原則，並隨著經濟、技術的發展，對其加以完善和發展；我國對生產者採用無過錯歸責原則，對銷售者採取過錯歸責原則，這不僅對生產者不公平，而且不利於保護消費者。 -
In contrast, the author believes that it is unreasonabie that the carrier have immunity from the fault of his crew under up - todate navigation condition. the author will justify his opinion by ; ( 1 ) discussing the history of liabiiity basis system and the evoiution of its civii iaw standardi the iiabiiity basis system experienced objective distribution stage to subjective stage, which indicates the negation of subjective f8ult
本文將從以下幾個方面進行論述： （一）分析歸責原則的發展歷程、民法基本觀念（即民法的本位）的演進，從宏觀的法律原理方面抽象論證航海過失免責的非正當性；歸責原則從客觀歸責到主觀歸責的發展，表明人類對主觀過錯的否定，雖然在意思自治原則下出現了一些過失免責，但各國都對此給以了限制。 -
