伊春市一次性木质卫生筷子未来的出路

筷子是我国人民必备的餐具之一，历史悠久。随着经济的发展，生活水平的提高，人们对餐具的要求也越来越趋向于向高品位的工艺和健康卫生的方向发展。自八十年代以来，我国生产的一次性木质卫生筷子，不仅遍及全国，而且出口到日本、韩国、东南亚及港、澳、台等国家和地区。一次性木质卫生筷子厂家的大批上马，虽然在短时期内取得了一定的经济效益，但同时也给濒临枯竭的森林资源带来大量的资源浪费。为保护生态环境，使有限的资源合理配置、高效发挥作用，作对伊春市的一次性木质卫生筷子企业进行了调查，并提出了相应的解决办法。

木屋梁多角度数控锯结构设计与研究

对木屋梁加工设备进行简要介绍,分析设计木屋梁多角度数控锯的合理性。通过对木屋梁多角度数控锯的工作过程的分析,确定木屋梁多角度数控锯结构的布局方案,利用solidworks软件对木屋梁多角度数控锯进行三维建模。完成了主锯组件、X、Z方向上移动组件和转动组件的结构设计及单位切削力、切削功率等主参数的设计计算。该设计使木屋梁多角度数控锯结构紧凑,调整方便,加工效率和加工精度高,大大提高了木屋梁多角度数控锯的工作性能。     

Physiological and psychological responses to prolonged light floor-impact sounds generated by a tapping machine in a wooden house

We investigated the physiological and psychological responses of nine normal men to the prolonged light floor-impact sounds of 60dBA and 80dBA generated by a tapping machine in a two-story wooden house. Blood pressure was measured, and a sensory evaluation was also conducted using the semantic differential method. The results obtained were as follows: (1) the increase in systolic blood pressure immediately after exposure to the light floor-impact sounds depended on the level of the sounds, (2) the variations in feelings due to the prolonged light floor-impact sounds were identified by factor analysis, and (3) the subjects showed no difference in comfortable feeling for the prolonged light floor-impact sounds of 60dBA and 80dBA, but differences in the variation of the systolic blood pressure were detected.Part of this research was presented at the 47th Annual Meeting of the Japan Wood Research Society, Kochi, April 1997     

木塑复合板主要工艺对材料性能的影响

研究了木粉与聚丙烯为主要原料的复合材料的主要力学性能和尺寸稳定性.实验结果表明:热压时间对复合材料的力学性能有一定的影响,加压时间为9min,复合板的力学强度较优,吸水厚度膨胀率小;木塑配比对复合材料的力学性能有较大的影响,随着配比的增加,板性能呈现逐渐下降的趋势;配比对吸水厚度膨胀率影响明显,木粉的比例越高,吸水厚度膨胀率越高.

Physiological effects in humans induced by the visual stimulation of room interiors with different wood quantities

To clarify the visual effects of room interior with wooden materials on humans, pulse rate, blood pressure, and brain activity were measured while the subjects were exposed to visual stimuli using actual-size model rooms. The wood ratios (the ratio of the area covered with wooden material to the whole area of the ceiling, walls, and floor) of the rooms were 0%, 45%, and 90%. Subjective evaluation was also conducted. In the 0% room, diastolic blood pressure decreased significantly, but the observed change in the autonomic nervous activity was relatively small. In the 45% room, a significant decrease in the diastolic blood pressure and a significant increase in pulse rate were observed. This room tended to have the highest scores in subjective “comfortable” feeling. The 90% room caused significant and large decreases in systolic blood pressure and diastolic blood pressure at the beginning of the test, but the large coverage of wood appeared to cause a rapid decrease in brain activity and an increase in pulse rate. The present study demonstrated that a difference in wood ratio in the interior caused different physiological responses, especially in the autonomic nervous activity, by using actual-size rooms for the first time.
