With the new matrix, first the inequality in reference [1] was extended to the case of positive rational number n/m, then by taking the limit, the above case was further extended to the case of positive real number.

利用该矩阵，将文献[1]中的不等式推广到正有理数n/m的情形。然后应用极限将正有理数的情形推广到正实数。

In addition, we obtain the following results:(1) A ring R is weakly unit-regular if and only if so is the n×n matrix ring Mn of R for any n≥1;(2) Let R be a ring such that R/J is regular.

另外，我们还证明了下面两个结果：(1)环R是弱幺正则的当且仅当Mn(n≥1)是弱幺正则环；(2)假设R是一个环且使得R/J是正则环。

Infants are particularly susceptible to nitrite-induced methaemoglobinaemia because fetal haemoglobin converts to methemoglobin more easily. In addition, infants have a low concentration of the reducing enzyme such that methemoglobin is not converted back to hemoglobin as readily.

婴儿特别容易患上由亚硝酸盐引致的正铁血红蛋白血症，是因为胎儿的血红蛋白较易转变为正铁血红蛋白，而婴儿的还原浓度低，较难把正铁血红蛋白还原为红血球素。

Between east and west, the mineralization in subalkalic intrusive complex is different. In the west, the veins are chiefly quartz veins, quartz veinlets and network veins, the wall rocks are mainly syenite and quartz monzonite. In the east, the fine quartz network veins, altered kata-rocks, alkali-syenite and syenite are dominant.

成矿作用在偏碱性侵入杂岩体的东部与西部有所不同，西部多以石英脉、石英细脉、网脉型为主，围岩以正长岩、石英二长岩为主；东部则多为石英细网脉和破碎蚀变岩型，围岩主要是碱长正长岩、正长岩。

This paper presented two regularization methods to solve this problem in SONAH: the standard Tikhonov procedure accompanied with two parameter selection procedures, the Morozov's discrepancy principle and the Engl's criterion, which were crucial to the regularization.

为此，通过两种不同的正则化方法解决上述问题：第一种方法采用标准的Tikhonov正则算子，并结合需要测量信号先验知识的Morozov偏差原则；第二种方法采用标准的Tikhonov正则算子，并结合不需要测量信号先验知识的Engl误差最小化原则。

We present an inverse method based on Tikhonov regularization theory. A regularized functional is established and regularization parameters are deduced with Arcangeli criterion and Morozov discrepancy principle. The functional is solved by sensitivity coefficients and Newton-Raphson iteration method.

充分考虑非线性瞬态热传导过程测温数据的误差特点，根据Tikhonov正则化理论，构造合适的正则化泛函，利用Arcangeli准则和Morozov偏差原理确定正则参数，采用灵敏度系数和Newton-Raphson迭代法求解该泛函。

At length they came up to the Boat; but 'tis impossible to express their Confusion, when they found the Boat fast a-Ground in the Creek, the Tide ebb'd out, and their two Men gone We could hear them call to one another in a most lamentable Manner, telling one another, they were gotten into an inchanted Island; that either there were Inhabitants in it, and they should all be murther'd, or else there were Devils and Spirits in it, and they should be all carry'd away, and devour'd.

这一切正合我的心愿。我让星期五和大副继续干他们的事，自己马上带其余的人偷偷渡过小河，出其不意地向那两个人扑过去。当时，一个人正躺在岸上，一个人还在船里呆着。那岸上的人半睡半醒，正想爬起来，走在头里的船长一下冲到他跟前，把他打倒在地。然后，船长又向船上的人大喝一声，叫他赶快投降，否则就要他的命。

By applying normal testing methods to two different examination papers in this essay, the author obtains the following results: Paper One tallies with normal distribution, indicating that the paper is more reasonable and objective; Paper Two is in the shape of negative skewness and lepmokurtic distribution, showing that the paper is easier than the required and less reasonable.

本文采用数理统计正态性检验法对两份不同的英语试卷考分进行了正态性检验，结果表明：试卷Ⅰ考分的分布服从正态分布，说明其命题难易适当、较为客观、合理；试卷Ⅱ考分的分布呈负偏态、尖峭峰，说明其命题较容易，且不合理。

The apparatus includes a positive contact (50) positioned so as to engage the positive terminal (42) of the battery, a negative contact (52) positioned so as to engage the negative terminal (44) of the battery, a third contact (54) positioned so as to engage the third terminal (46) and a logic circuit (72) connected to the positive, negative and third terminals.

所述装置包括：一个设置用于与电池的正端（42）连接的正触点（50）；一个设置用于与电池的负端（44）连接的负触点（52）；一个设置用于与电池的第三端（46）连接的第三触点（54）；和一个与正触点、负触点和第三触点连接的逻辑电路（72）。

In this thesis, some theories and approaches related to continuous dynamics, discrete dynamics, impulsive dynamics, operator theory and numerical simulations are used to investigate dynamical behaviors including the existence and globally asymptotic stability of periodic solutions, permanence, extinction, and all kinds of complexities, and meanwhile the possible effects of delay and impulse on the dynamical behaviors are discussed.

我们的这些结果显示出这三个时滞周期系统正周期解存在且全局渐近稳定的充分条件在形式上几乎能够很好的与相应的无时滞自治系统正平衡态存在且全局渐近稳定的充分条件相对(来源：A5babBC论文网www.abclunwen.com)应，这些结果也显示了时滞对系统正周期解的存在性和全局渐近稳定性是有影响的，它们推广并改进了一些已有的相关结果。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
