In this paper we mainly utilize super and sub solution techniques, use comparision principle and construct appropriate supersolution and subsolution by eigenfunctions to discuss two kinds of nonlocal nolinear parabolic systems with homogeneous Dirichlet boundary condition.

两类非线性抛物方程解的整体存在与爆破性质本文主要利用上下解方法，运用比较原理，通过特征函数等构造适当的上下解讨论了两类抛物型方程组解的整体存在与爆破。

The stress-strain curves of Cu-Zn-Al alloys at different temperatures have been plotted on the tensile machine with the aid of electrometry. The main results were as follows: 1. When specimens were deformed within the range of M_s and M_d, the critical stress for inducing martensitic transformation increased with the temperature, and there existed a linear relationship between them. 2. When specimens were deformed above Af, complete pseudoelasticity might be obtained theoretically, which might be damaged, h...

在拉力试验机上用电测法测绘了Cu-Zn-Al合金在马氏体相变点上下各温度的σ-ε曲线，所得主要结果如下：(1)试样在M_s与M_d之间加载，随着温度升高，诱发马氏体相变所需临界应力增大，且加载温度与临界应力之间存在着线性关系；(2)在A_f点以上加载，理论上可获得完全的伪弹性，但加载温度过高或应变量过大，均会损害伪弹性；(3)试样在M_s点上下温度区域变形，得到的伪弹性回复和形状记忆回复之和在80%以上，但在M_s点附近总回复量出现一极小值，且伪弹性回复在M_f点以下又有所回升。

Based on upper and lower solutions,the existence and uniqueness theorem are established.

以上下解为基础，建立了解的唯一性定理，在适当条件下，构造具体的上下解，得到了解的存在性和唯一性。

While we found some hypergamy and hypogamy at work on the politico-economic structure, there is actually no sign of hypergamy and hypogamy in Russian spouses' daily life. We need more research and discussions to evaluate the significance of hypergamy and hypogamy.

然而在衡量客观结构的同时，实际生活中的俄籍配偶却无关上下嫁，因此上下嫁的意义与重要性仍有待更多评估与讨论。

From this,it is proved that when all the ratios of a subaddtive function defined on the interval(0,+∞) to the value of its variable form a bounded function ,the subaddtive function must have supremum and infimum functions,which are homogeneously linear functions.

从这一结果出发证明了，当定义在(0，+∞)上的次可加函数与其自变量之比为有界函数时，次可加函数必存在上下确界函数，并证明了其上下确界函数均为齐次线性函数。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
