Take the Hall Voltage Sensor effect as the foundation, has studied the magnet and the ferromagnetic component is away from and the magnetic field strength relations, discovered in 0-150mm, the distance change all will cause in the air the magnetic induction intensity change, in which 0-80mm changes the quantity quite to be obvious, in 40mm, basically will in particular assume the index relations change.

The following conclusions have been made in this paper.(1) Based on CO_2 flux data of eddy covariance, variation characteristics of gross primary productivity in four flux observation stations were studied, which are an alpine meadow, an alpine shrub meadow, a swamp alpine meadow and a steppe alpine meadow at Dongxiong. The results show that photosynthetic capacity of the alpine meadow is the highest, and the annual total GPP is 652.2g C/m~2. Daily-differencing approach is used to analyze the random error of CO_2 fluxes measurements. The results show that the distribution of random error follows more closely follows a double-exponential, rather than a normal distribution, capturing the high peak and thick tail, and the random error varies with environment variables, which violates the assumptions for the ordinary least squares fitting with normality and homoscedasticity, consequently, we introduce maximum likelihood method for parameter optimization.

本文主要在以下几个方面开展工作并获得了一些认知和结论：(1)通过分析样带区域内高寒草甸、高寒灌丛、沼泽化湿地和草原化高寒草甸四个通量观测站点草地生态系统总初级生产力变化特征，研究结果表明HBBT矮嵩草草甸生态系统植被光合作用能力较强，年GPP总量为652.2 gC/m~2，明显高于其他三种生态系统；通过利用"单塔日变化法"获得四站点通量观测数据随机误差，结果表明通量观测随机误差概率分布呈现尖峰厚尾的特征，与正态分布相比，更服从双边指数分布，进一步分析表明通量观测随机误差随环境变量(风速、温度和光合有效辐射)的变化而变化，这违背了普通最小二乘法进行生态过程模型参数优化正态分布且误差同质的假设，因此本研究中引入最大似然法进行生态过程模型参数优化。

In the area of sharp depth change, the pattern of average current field varies sensitively with wind speed change, while in the area of flat and gentle bottom, insensitively. The current direction in shallow water was consistent with the direction of the wind, while against the wind direction in deeper water and responded slowly.

在水深水平变化较大的区域，垂直平均流场结构对风速变化的响应较为敏感，易形成环流，浅水区垂向平均流向和风向一致，深水区则和风向相反；水深变化较小的水域，流场结构对风速变化的响应则较为迟钝。

Secondly, it is not the same fractal diagram by the same codes of IFS to produce fractal diagram. The two graphs are extraordinary similar, but they are different in detail. The problem is researched and the algorithm which calculates the intersection points of two graphs created by the same coefficient of the IFS is proposed. The curve described changing of the intersection points number is drawn. The conclusion is that the curve fluctuates in the tiny range and is smooth when it is seen as a whole. In fact, the curve is a fractal curve.

其次，针对同一IFS迭代码两次迭代绘制得到的分形图并非完全相同这一问题展开研究，提出了IFS分形覆盖相交交点变化曲线的概念，给出了覆盖相交交点变化曲线的绘制算法，在此基础上进一步研究了分形覆盖相交交点变化曲线的变化率情况，得到了分形覆盖相交交点变化曲线宏观上比较光滑，但实际上小范围内异常波动的实验结果。

The southern branch of ACC bypassing the north part of the Kerguelen Plateau behaves like an annual variation while the southern one displays a semi-annual variation. The variations of both branches are consistent with the variations of the wind stress in both regions.

Provided that real cost and opportunity cost are all variable,so is labor divisionand exchange.

如果考虑到实际成本和机会成本都是可以变化的，那么分工与交换的变化，不仅是交换的量的变化，而且分工的方向也会发生变化。

The results show that the Lande factors are 2.002~2.003, which have little change, and that of coal from Zhangji coal mine are little larger than that form Baijigou coal mine. Small particle size, high oxidation temperature and long oxidation time can lead to high corventration and high line height. However, the trend of line width is dispersive.
