Abstract:

The big Wenchuan Earthquake has passed for a year, but the huge disaster caused by the earthquake cannot be forgotten yet. The scientific development view should be better carried out and the earthquake mechanism should be analyzed thoroughly, so that effective scientific reference can be provided for consideration of the prevention and reduction of future disaster.

Pollution survey of carbonyl compounds in train air

LU Hao, ZHU Lizhong

Frontiers of Environmental Science & Engineering 2007, Volume 1, Issue 1,   Pages 125-128 doi: 10.1007/s11783-007-0023-3

Abstract: The train is an important vehicle in China, but its air quality has important impacts on passengers health. In this work, pollution from carbonyl compounds was measured in the air of six trains. The objectives of this work were to investigate carbonyl compound levels in selected air from trains, identify their emission sources, and assess the intake of carbonyl compounds for passengers. The methods for sampling and analyzing 10 carbonyl compounds such as formaldehyde, acetaldehyde, acrolein, acetone, propionaldehyde, crotonaldehyde, butyraldehyde, benzaldehyde, cyclohexanone, and valeraldehyde in indoor air were proposed with the sampling efficiency, recovery, and detection limit being 92% 100%, 91% 104%, and 0.26 0.82 ng/m, respectively. It was indicated that the total concentrations of carbonyl compounds were 0.159 0.2828 mg/m with the average concentration of 0.2330 mg/m. The average concentrations of formaldehyde, acetaldehyde and acetone were 0.0922, 0.0499, and 0.0580 mg/m, accounting for 42.6%, 21.4%, and 24.9% of the total concentrations of carbonyl compounds, respectively. The carbonyl compounds probably came from woodwork and cigarette smoking. The intake of carbonyl compounds for the passengers was approximately 0.043 0.076 mg/h. The carbonyl compounds in train air could be harmful to human health.

A survey of instantaneous poles for a class of two-degree-of-freedom spherical mechanisms

Soheil ZARKANDI

Frontiers of Mechanical Engineering 2014, Volume 9, Issue 4,   Pages 344-353 doi: 10.1007/s11465-014-0320-z

Abstract:

This paper is a detailed exploration of instantaneous poles for a class of two-degree-of-freedom (two-DOF) spherical mechanisms (SMs) with seven links or bars. For two-DOF SMs, the secondary instantaneous poles (the ones which cannot be found by direct inspection) must lie on the specified great circles. For many of these mechanisms, however, some of these great circles cannot be obtained by a direct application of Aronhold-Kennedy theorem. This paper presents geometrical and analytical techniques to locate these unknown great circles for three topologies of seven-bar two-DOF SMs.

Keywords： spherical mechanisms     instantaneous poles     Aronhold-Kennedy theorem     great circles     pencil of meridian
