The concept of the weighted logarithmic power mean is introduced; its relation with two-parameter mean is given; the inequality for weighted logarithmic power mean is derived; the magnitude relation among upper bounds of geometric mean and arithmetic mean of geometrically convex functions are made certain.

建立了几何凸函数的对称拟算术平均不等式，对文献[1]提出的不等式进行了推广统一；引进加权对数幂平均的概念，建立起其与双参数平均之间的关系，得到加权对数平均不等式，从而确定了几何凸函数的几何平均、算术平均的上界的大小关系；最后，提出了几何凸函数的对称拟算术平均不等式的推广问题。

Only two decades after Arkwright machinery was introduced into this country, the market for yarn was becoming national and the spinning process was becoming a true factory operation as it was in England.

阿克赖特的机械被引进美国之后仅仅二十年，纺纱市场已扩展到全国，纺织工序与英国一样成为真正的工厂化操作。

Arouse controversy likewise, the talent that is 51 extravagant is introduced.

同样引起争议的，是51大手大脚的人才引进。

Our corrugated arrestor with anti-exsplosion with some state of ants in British , Germany , Nloing with better manufacturing and inspection equipment,have good features , such as compact structure ,good reliability especial for H2、 O2、 LPG and so on.

我公司综合引进英国、德国等公司的先进技术，配之先进的加工设备和完善的检测装置，生产的防爆波纹阻火器，具有结构紧凑，可靠性高，阻火芯件防爆、防腐、阻火性能强、便于清洗等优点，特别适合于氢气、氧气、液化气等特殊介质。

This paper presents a method for getting initial basic feasible solution of linear programming problem with an artificial variable,comparing with a traditional two-stage way ,it has low computation amount and needs less memory cells for computing,and improve two-stage way simple method.

提出了一种通过对线性规划问题增广矩阵的初等行变换后，引进一个人工变量即可求得初始基可行解的方法，该方法与传统的两阶段法相比，具有计算量小且占有存储空间少的特点，从而简化了二阶段单纯形法。

In order to increase the computation efficiency, artificial dissipation, variable time step and enthalpy damping acceleration techniques are used in the five-step Runge-Kutta time stepping.

在定常的计算中，采用5步Runge-Kutta时间推进，引进人工耗散，应用了当地时间步长、焓阻尼等加速收敛技术。

Our products are advanced in structure and are made with exquisite artisanship, with a good variety and high quality. They are widely used as corollary fitting for pipeline setting by enterprises in power, petrol industry, chemical industry, and metallurgy industry, etc, as well as used in some key engineering projects.

生产的产品结构先进、制作工艺精湛，规格齐全、质量上乘，从而广泛使用于电力、石油、化工、冶金等管道行业引进装置配套及重点工程建设上，深受用户信赖。

I don't know where Greg got his idea of applying the concept to a crack anchoring device. Perhaps it was from the Jumar ascender, which uses a more-or-less constant angle cam to clinch the rope. At any rate we have Greg to thank for introducing the concept to crack anchoring technology.

我不知道Greg从何获得此一主意用於裂隙确保，或许是从犹玛攀升器，因其使用类似的等角凸轮钳住绳子，无论如何我们都要感谢Greg将此概念引进到裂隙确保技术上。

It is likely that the severity of this pest in some regions of China resulted from the high susceptibility of introduced ash tree species from North America to EAB.

中国部分地区发生的花曲柳窄吉丁灾害应该归属于引进的北美白蜡树种对本地害虫敏感所致。

Firstly, as the population of the landmass immigrants and local residents kept growing, people had to assart more fields and introduce new crops to meet their needs. Secondly, people also consumed plenty of woods for their daily lives. Thirdly, the development of lumbering led to the further vanishment of forests. Besides, the gerentocratic pillage was another reason that couldn't be neglected.

首先，由于大陆移民和当地居民人口的不断增加，必然要求扩大田土开发的面积，引进新作物以满足人们日益增长的生产需要；其次，人们的日常生活也需要消耗大量的林木资源；再次，木材业的发展进一步导致森林的消失；此外，统治阶级的掠夺也是一个不可忽视的因素。

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。
