yield-mass distribution

What is called that the income distribution effect of investment is the theory, which the quantitative growth of the investment leads to the descending of the capital yield and all of these will make the proportion that the capital income share accounts for the national income change.

所谓投资的收入分配效应是指投资的数量增长引起资本收益率下降，从而资本收入份额占国民收入的比重会发生变化。

大豆产量空间分布形成原因的探讨

This paper studied the basic properties of metallocene linear low density polyethylene ( mLLDPE), including density, melt flow rate, molecular weight distribution, melt point, yield strength, tensile strength at break, elongation at break and Izod impact strength.

研究了茂金属线型低密度聚乙烯（mLLDPE）的基础性能，包括密度、熔体流动指数、熔流比、分子量及其分布、熔点、屈服强度、断裂强度、伸长率、冲击强度等。

This paper discusses a continuous time yield management model with the following characters: customers arrive according to a nonhomogeneous Poisson process, each arriving customer has maximal& minimal reservation prices, the distribution of which depends on the time of arrival.

研究了具有如下特征的连续时间收益管理问题：顾客的到达为时依强度的泊松过程，每个顾客具有最大、最小保留价格，其分布依赖于到达时间。

Therefore, the rule about effect of temperature distribution with time on yield formation of various ecotypes of soybean has been quantitatively revealed.

从而，定量地揭示了温度的时间分布对各生态型大豆品种产量形成的影响规律。
