Examples
- Initial mass distribution
初始质量分布 - In the present experimental work i tried to learn some about the absorption phenomenon by allowing superheated ammonia vapor , which is existed in a cylinder , to flow into a test cell to be absorbed into ammonia liquid mixture with certain initial ammonia mass fraction
在本实验研究中,首先在氨蒸汽罐中制备好过热氨蒸汽,然后将过热氨蒸汽注入到实验件主体,在其中氨蒸汽被一定初始质量浓度的氨水混合液吸收。对该吸收现象现象进行了研究。 - The main content is : 1 . through the pan evaporation experiments , in which the effects of wind speed , area and mass on the evaporation process has been studied , it is found that the behaviors of mixed and pure liquids have different characteristics , which cannot be explained by the theory of boundary layer control and basic evaporation
主要内容有: 1 、本文用浅盘蒸发法考察了风速、蒸发面积和初始质量对油蒸发过程的影响,发现混合液体蒸发与纯液体蒸发行为有不同特点,将蒸发分为边界层控制步骤和基本蒸发不足以反映其蒸发特点。 - Comparing with the current observations , which include the number density distribution in space , mass function , etc . , the so - called standard modes for both the power law and gaussian cluster initial mass functions are selected among many runs of simulations . the deviation from the standard modes , which is resulted from the change of the parameter for the initial conditions , is discussed in detail . the discussion of the model parameters is also presented although they are adopted as the typical values based on previous work
对应一定的初始分布我们发现无论是幂律的还是对数高斯的球状星团初始质量谱经过长时间的动力学演化都会得到和现在银河系观测到的球状星团系统相符的对数高斯的质量分布;动力学演化会明显地改变球状星团系统的空间密度分布,靠近银心区域的球状星团瓦解得更多;经过动力学演化后的球状星团速度分布函数在靠近银心的区域明显得不同于初始分布,初始拥有较大轨道偏心率的球状星团更容易瓦解。 - The number density distribution of globular cluster in space will change with time due to the dynamic evolution , especially for those in the central region of the galaxy ; 5 . for the power law initial cluster mass function , the peak value of the mass function after the dynamic evolution is sensitive to the lower limit of the initial mass function we adopt . the suggested value in this paper is - 104m , which is consistent with that reduced from the dynamical analyses for the giant molecular clouds
对于幂率的初始质量谱,球状星团系统动力学演化后质量分布的转折点质量主要是由初始质量函数的质量下限决定的,最为适合的值为10 ~ 4m _ ;幂率的初始质量谱的谱指数对球状星团系统动力学演化后质量分布的转折点质量也有影响,其最佳值为1 . 5 2 . 0 ;经过大约5gyr的动力学演化,幂率的初始质量谱就会演化成为高斯的对数质量分布并具有在随后的动力学演化中保持对数高斯形式质量分布的特性。
