The structure and strength of this meridional flow is believed to play a key role in determining the strength of the Sun's polar magnetic field, which in turn determines the strength of the sunspot cycles.

的结构和本经向流的力量，相信在确定太阳的极地磁场，从而决定了太阳黑子周期的力量力量方面发挥关键作用。

According to analyzing features of multiformity and dynamic variability for designing and manufacturing knowledge of mechanical products under network environment,the 4-dimensional information model of product lifecycle-oriented information resources is presented in this project, and it is extended to become a product multidimensional information model with production data formation process.

本项目在对网络环境下机械产品设计制造知识的多样性和动态变化性特征分析的基础上，提出了面向产品全生命周期的4D信息模型，并将其扩展为一种以产品数据形成过程为核心的多维信息集成表述模型。

Methods1. Compared with adult female rats, aged female rats without oestrum were chosen by using RIA technology and sexual hormone was changed remarkably. Theses aged rats were divided into three groups（GNK group, HRT group and control group）. Treated them respectively with GNK, nilestriol and distilled water 3 months.

通过用阴道脱落细胞涂片检测发情周期的改变，放免法测定血清性激素的水平，与正常青年雌性大鼠比较，选择阴道脱落细胞无发情期改变，血清性激素水平有增龄性改变并且差异有显著性的老年雌性大鼠作为研究对象，分别用中药复方更年康和尼尔雌醇灌胃3个月，观察中药复方更年康对老年雌鼠的治疗作用。2。

Under the condition in which out-of-stock isn't permitted, partial elasticityof total cost related to purchase quantity and period is studied.

提出随机局部弹性的概念，讨论了相应的运算法则，研究了不允许缺货的存贮模型中，总费用对采购量与采购周期的局部弹性。

On the basic of NNLSE and the Poisson equation, using the Green function approach, we obtain the response function of the lead glass of finite-size, which is a strong nonlocal medium. Starting with the paraxial ray equation, we obtain the analytical solutions of the oscillation trajectory and period of the beam.

基于非局域非线性薛定谔方程以及热传导的泊松方程，采用格林函数法求出了强非局域介质铅玻璃的响应函数和临界功率；从光线方程出发得到了偏离材料中心入射的光束中心振荡轨迹以及周期的解析解。

The authors also analysed the gravitation influence on the oscillation period of the inertial scale when it is placed in different divtections.

介绍了惯性秤的基本原理，推导出惯性秤在水平、垂直和倾斜放置时振动的动力学方程，并在此基础上研究了惯性秤不同放置时重力对惯性秤振动周期的影响，同时通过实验来验证推导的结果。

For example, when he represented his country in the Belgian Pavilion at the 2001 Venice Biennial, Tuymans produced a cycle of works based on the murder of the first post-independence Prime Minister of the Congo, Patrice Lumumba.

举例来说，当他代表他的国家在比利时馆在2001年威尼斯双年展， Tuymans制作了一个周期的工作基础上谋杀后的第一个独立的总理，在刚果卢蒙巴。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
