Conventional reliability theory is based on binary-state assumption and probabilityassumption. However in many cases the binary-state assumption is not acceptable, i.e., thesystem failure cannot be reasonably defined in a crisp way but should be in a fuzzy way,and thus fuzzy-state assumption should be taken in place of the binary-state *** reliability theory is a form of fuzzy reliability theory and based on the fuzzy-stateassumption and the probability assumption. Therefore profust reliability is a new reliabilityindex and can be used to comprehensively characterize system reliability behavior. Failuresof the longitudinal fly-by-wire system in an ACT test aircraft are divided into threeclasses: safety-fatal, task-fatal and maintenance-required, and profust reliability analysisfor this system is performed. Further, a new index of failure criticality on top of profustunreliability is defined so that this new index is not only adequate to reasonably distinguisheffects of distinct failure modes, but also able to directly account for the effects of failuremodes on system reliability behavior. The conclusion of this paper is that it is reasonable totake the profust reliability as the system design index.

伯林自由理论的基本致思取向是以多元论对抗一元论。然而,由于他严格区分自由与自由的条件,坚持自由条件的任何改善都与自由本身无关,结果客观上把自由与其他价值观如知识、平等、民主等绝对地对立起来,在自由与其条件之间挖下一条不可逾越的鸿沟,致使其自由理论陷入内在困境,出路在于把自由本身重新置于自由的条件这一实际前提之下。

Four different media for growing Coprinus comatus strain CC16-8 in submerged culture were screened and subjected to orthogonal testing according to L_ 9 （3~ 4 ）. Data revealed the optimum medium composition （adjusted to pH 8.0） to be: sucrose 3%, corn powder 2%, wheat bran 4%, KH_ 2 PO_ 4 0.1% and MgSO_ 4 ·7H_ 2 O 0.05%. Mycelium dry weights using this medium reached 8.63 g/L after submerged culture for 7.5 d.

The patternless casting manufacturing(PCM) technique adopts a new method ofdouble scanning which combines the principle of discreteness and deposition with the resin-bondedsand technique. Two main factors, the liquid penetration regularities in the space between particlesand the shape and dimension of the agglomeration unit body, are studied qualitatively andquantitatively. This provides the theoretical basis for selecting the forming technical *** experiments verify the analysis.

One important purpose to investigate medicinal plants is to understand genes and enzymes that govern the biological metabolic process to produce bioactive compounds. Genome wide high throughput technologies such as genomics, transcriptomics, proteomics and metabolomics can help reach that goal. Such technologies can produce a vast amount of data which desperately need bioinformatics and systems biology to process, manage, distribute and understand these data. By dealing with the 'omics' data, bioinformatics and systems biology can also help improve the quality of traditional medicinal materials, develop new approaches for the classification and authentication of medicinal plants, identify new active compounds, and cultivate medicinal plant species that tolerate harsh environmental conditions. In this review, the application of bioinformatics and systems biology in medicinal plants is briefly introduced.

An advanced method is presented for analysing the dynamic behaviours of annularcascade structures. The method may be considered as the combination of the chain loadingtechnique to dynamic substructure analysis and group algorithm. Its general analyticalprocedures and concrete equations are shown in this paper. Dynamic analysis for structureswhich have both periodically cyclo-symmetric and annular cascade geometric characteristicscan be realized. Under the precondition that the computational accuracy is ensured,this method shows reliability, practicability and remarkably economic benefits.
