The climate characteristics of TCP were analyzed with variance analysis,trend coefficient and linear regression technique,followed by comparison with those of annal total rainfall in East China.Results show that the spatial distribution of TC rainfall is not uniform in East China with the...
结果表明:华东地区登陆台风降水量空间分布不均匀,福建东南沿海地区最大,具有向西北方向递减的趋势,这种趋势与地形等因素有关;TCP的年际变化明显,9 a和15 a周期显著;TCP年代际变化表现为20世纪50年代最多,70年代前开始减少,比华北地区台风降水减少出现的时间提早10 a;TCP与总降水两者的时间演变特点差异较大。

Compared with the same wave problems with conventional Dirichlet boundary conditions, the absorbing boundary conditions can reduce the numerical reflection on boundaries and avoid solution distortion. In addition, the central differences method is economic in memory requirement and computing time compared with implicit integral method.
结果表明:该解法在空间上具有谱精度,在时间上达到二阶精度;与第一类边界条件相比,吸收边界有效地削弱了边界上的数值反射,避免了解的失真;使用中心差分的时间积分方法同隐式积分方法相比,适合波的传播特性,避免了矩阵求逆运算,并且占用的计算机内存小。

In this thesis, the virtual boundary integral equation is based on double layer potential with the virtual density to be determined on virtual boundary. Since this integral equation related to double layer potential only involves the computation of the normal derivative and second normal derivative of fundamental solution, the exponential integral function is not involved in it, so numerical computation for the exponential integral function is avoid.
本文则基于双层位势,引入虚拟矩密度函数来建立虚边界积分方程,并首先对时间变量进行解析积分,在虚、实边界上采用常单元和等额配点离散,该方程只涉及含基本解的法向导数及其二阶法向导数项的计算,对时间变量进行解析积分后,不会出现对指数积分函数的空间变量的积分计算。

This steam temperature did not calculate too high, this time the human new outer space exposure suit already had the long time to resist 3000 degrees high temperature abilities, as for the steam formidable pressure also insufficient was worry, only was in this steam the unknown material whether had the danger, extremely anxious and puzzled, was good in them is the direct impact outer space, and is flung fast to the planetoid after death, otherwise density too Gao Huochang the time contact definitely could have some kind of unknown event.
这蒸汽的温度不算太高,此时人类新型太空防护服已经具备长时间抵御3000度高温的能力,至于蒸汽的强大压力也不足为虑,只是这蒸汽中未知物质是否具有危险,十分令人担忧和困惑,好在它们是直冲外层空间,并被快速地甩向小行星的身后,否则浓度太高或长时间接触肯定会发生某种未知的事件。

The results show that a the variation of annual mean runoff of Huayuankou section exist an intrinsic dynamic mechanism, which is the results of joint action of affecting factor of periodicity and non-periodicity, having obvious chaos characteristic; b the correlation dimension of attractor of phase space is 5.09 and saturation inserted dimension is 14. It shows that to establish a mathematical model of the annual mean runoff system of Huayuankou at least requires 6 independent variables and the required saturation inserted dimension for rebuilding phase space is 14; c the steady estimate of Kolmogorov entropy is 0.14, showing the average predictable time of the annual mean runoff variation of Huayuankou is about 7 years and; d using nonlinear deterministic chaos model is more suitable to describe the variation of annual mean runoff of Huayuankou.
结果表明:①花园口年平均径流量变化存在着内在动力学机制,是由周期性和非周期性影响因子共同作用的结果,具有明显的混沌特性;②相空间吸引子的关联维为5.09,饱和嵌入维数为14,这说明要建立花园口年平均径流系统的数学模型,至少需要6个独立变量,重构相空间所需要的饱和嵌入维数为14;③Kolmogorov熵的稳定估计为0.14,说明花园口年平均径流量变化的平均可预报时间大约为7年;④用非线性确定性的混沌模型比完全的随机模型更适于描述黄河花园口年平均径流量的变化。

For the leaf area index of the three forest types, there was a similar variation trend, i.e ., increased first and decreased then, with the maximum presented in mid-July or August for Q. mongolica and J.mandshurica forests while in mid-August or September for F. rhynchophulla forest. The canopy porosity of the three forest types also had a similar variation trend, but opposite to leaf area index, being decreased first and increased then, with the minimum presented in mid-June, July, August or September. The analysis of variation coefficients of leaf area index, transmitted direct gap light, and transmitted diffuse gap light indicated that the spatial pattern of leaf area index in July-September was the main factor affecting the spatial distribution of transmitted diffuse gap light.
结果表明,3种林型的叶面积指数变化总体趋势是一致的,均呈先上升再下降的单峰曲线,蒙古栎林和胡桃楸林都是在7月中旬或8月中旬达到最大峰值,花曲柳林是在8月中旬或9月中旬达到最大峰值;3种林型冠层孔隙度的变化总体趋势也是一致的,呈先下降再上升的单峰曲线,不同样地峰值出现的时间也不同,最低峰值在6、7、8、9月中旬均有出现;通过对不同月份的叶面积指数、林下散射光、林下直射光的变异系数分析表明,7—9月叶面积指数的空间格局是影响林下散射光空间分布的主要因素。
