According to the view in "criticism of Confucianism and Moism"by Moruo Guo,Mozi's "AntiMusic"is used in a broad sense,and not confined simply to the "music"itself,so it con be concluded that Mozi's "Antimusic"is opposite to "Hedonism".

从郭沫若在《孔墨的批判》中所列观点中可以看出,墨子&乐&的范围是广义的,而仅仅局限于&音乐&,因而不可能得出墨子&乐&就是反对音乐的结论。

The amount of Ca8-P in soil with CRMP treatments was lower than that of CMP treatments. The changes of the amount of Al-P, O-P, Fe-P and Ca10-P in soil were neglectable during the course of experiment.3. The shoot and root weight of sorghum increased through application of phosphorus, in addition, The increase of sorghum shoot and root weight was greater than that of common monoammonium phosphate due to the slow release of nutrients from CRMP. The accumulative uptake of phosphorus in shoot and root with CRMP treatment was greater than that with CMP treatment in low (75 mg P2O5/kg soil ) and high(150mg P2O5/kg soil)rates, especially on middle stage, and in high phosphorus rate, this advantage was more obvious than that in low phosphorus rate.

磷肥的施入,促进了高粱地上部和根部的生长,而控释肥由于缓慢释放养分,与作物吸收相一致,更能促进高粱的地上部和根部干物质积累;对于高粱地上部及根部的磷素累积,在两种施磷水平下控释处理地上部及根部磷素累积量均大于控释处理,尤其是在中期,而且高磷水平下优势更加明显,低磷控释处理的磷素累积量能达到高磷控释的累积量,即减少一半的用量即能达到同样的效果;在氮、钾、钙、镁相同的水平下,控释处理比控释处理更能促进地上部及根部氮、钾、钙、镁累积量,这种优势在中期表现最明显。4。

The Fresnel lens in the optical receptor spotlights the headlamp beams to form their image at the 1-meter distance between the optical receptor and headlamps. CMOS camera as an image sensor, takes the photos of their images, which are captured by VG-M201, The application of some digital image processing techniques to these images, such as edge-picking up、 least-square fitting-curve algorithm, is to calculate the offset position/angle of optical axis of the high beams and the nodical offset of the unsymmetrical facular light and shade cut-off line of the low beams.

系统的图像采集工作是利用受光箱中的菲涅耳透镜在1米的测量距离上聚合前照灯灯光,由CMOS摄像头作为图像传感器件,照入灯光远光光斑和对称近光图像,由嵌入式处理器对捕获的图像运用边缘提取、最小二乘法拟合曲线等数字图像处理技术计算出远光主光轴偏移角度以及对称近光光斑明暗截止线拐点的偏移,实现了前照灯近光对称光斑的自动测量。

The current methods of studing the mechanism of asthma aboard is take the nonasthmatic ASMCs as object and study the effect of every single related factor on the on proliferation of nonasthmatic ASMCs in vitro respectively. However, as the phenotypes and functional status of asthmatic and nonasthmatic ASMCs are different, it's deficient to infer the proliferative feature and the signal transduction pathway of asthmatic ASMCs in vivo from that of nonasthmatic ASMCs induced by every single factor in vitro.

目前国内外通常是分别研究与哮喘有关的各种影响因子对哮喘ASMC增殖的影响,但由于哮喘ASMC和哮喘ASMC的表型和功能状态存在差异,这种在体外分别以单一因子诱导哮喘ASMC增殖来推断哮喘ASMC体内的增殖特性及信号转导途径的方法尚存在一定局限性。
