Threatened fishes of the world: Cyprinus micristius Regan 1906 (Cypriniformes: Cyprinidae)

Conservation status, identification, distribution, abundance, habitat and ecology, conservation actions and recommendations of a endemic cyprinid fish, Cyprinus micristius were introduced based on data and knowledge from a GEF project in Lake Dianchi, Yun

TRANSMISSION ELECTRON-MICROSCOPY STUDY OF N+-IMPLANTED SILICON ON INSULATOR BY ENERGY-FILTERED IMAGING

We report on the first study of N+ -implanted silicon on insulator by energy-filtered imaging using an Opton electron microscope CEM 902 equipped Castaing-Henry electron optical system as a spectrometer. The inelastic images, energy window set at DELTA-E = 16 eV and DELTA-E = 25 eV according to plasmon energy loss of crystal Si and of silicon nitride respectively, give much structure information. The interface between the top silicon layer and the upper silicon nitride layer can be separated into two sublayers.

ADAMS在卡钳设计仿真中的应用

虚拟样机技术是利用计算机分析软件，通过建立运动学、动力学模型来分析和评估系统的性能，从而为物理样机的设计和制造提供参数依据.本文简述了虚拟样机技术和动力学仿真软件ADAMS以及虚拟样机开发的流程；介绍了它在卡钳机构仿真分析中的应用。
