Changed of moon phases are brough about by the non - self - luminosity and the opacity of the moon . as the moon is a spherical body , sunlight can only illuminate half of the moon . viewing from different directions , the moon will appear to take the shapes of a circle , a semi - circle , a crescent , a gibbous or even completely invisible at all when its dark side faces the earth 由于月球本身不发光，只是反射太阳光，所以当月球运转时，月球地球和太阳三者的相对位置便会不断变化，因此，地球上的观测者所见到月球被照亮的部分也在不断变化，从而产生不同的月相
Then analytical measurements of the noise were carried out on both of the turbines by means of modern acoustic apparatus and a conclusion has been found that the noise of the concentrated wind energy turbine is lower than the one of the ordinary wind energy turbine and the root of the trouble to cause noise chiefly originates from the turbine blade . besides , the result of analytical measurement also reveals that the power output both of the wind energy turbines will increase with the increase of the wind speed and unfortunately does the noise too . in order to lower the noise , a measures of noise reduction have been advanced that an active method is to develop a wind energy turbine run at a lower rating of wind speed while the passive method is to adopt a board drilled tiny holes , having established a sound technological basis for the development of a kind of wind energy turbine of low noise and high level in the world 主要对浓缩风能型风力发电机在正常运转时，噪声产生的机理进行了理论分析研究，并与普通型风力发电机的噪声进行了对比实验分析；利用现代声学测试手段对两类机型进行测试与分析，得出浓缩风能型风力发电机产生噪声低于普通型风力发电机和叶轮是风力发电机产生噪声的主要部件的结论；通过对两类机型的噪声、输出功率的测试，得出随着风速的增加，两类风力发电机的输出功率在增加，产生的噪声也在增加的结论；提出了进一步降低浓缩风能型风力发电机噪声的措施，从主动降噪方面，研制低额定转速的发电机；从被动降噪方面，采用微孔穿板的降噪结构；为研究开发一种国际上低噪声、高水平的风力发电机打下了良好的技术基础。
The stability output second harmonic generation ( shg ) experiment results of single - longitudinal mode and multi - longitudinal mode with long cavity were explained reasonably with these rate equations . the high polarization of fundamental wave in the isotropic laser media nd : yag with type - i critical phase - matching lbo was studied with the rate equations including polarization of fundamental light . using the polarization function of lbo , a quartz full - wave plate was introduced into the cavity , a kind of birefringent filter by considering the combination of the polarization function of the type - i critical phase - matching doubling frequency crystal lbo and the quartz whole - wave plate was constructed 将腔内多纵模倍频速率方程推广应用到准三能级蓝光激光器中，分析了一个纵模、两个纵模、多个纵模时的噪声情况，合理地解释了实验中激光器单纵模运转以及长腔多纵模运转时稳定输出的实验现象，同时利用该速率方程分析了以各向同性激光晶体nd : yag为工作物质，类临界相位匹配lbo为倍频晶体的蓝光激光器中基频光偏振特性，合理利用类临界相位匹配lbo倍频晶体的偏振特性与引入的石英晶体全波片构成双折射滤光片，通过选单频来抑制噪声，获得了蓝光低噪声的稳定输出。
