The paper presents a new technique of producing methane with solar heating in cold area,develops the experiment system for producing methane with solar heating,studies the heat-transfer content、temperature difference of heat interchanger and temperature field of soil around the digester fermenting,gives the value of heat .

为解决北方地区由于冬季气温、地温低，沼气生产存在产气率低、使用率低、原料分解率低、沼气使用综合效益差等问题，文章介绍了一种利用太阳能加热制取沼气的方法，建立了太阳能加热制取沼气的试验系统，研究了换热器的加热量、进出口温差以及沼气池周围土壤温度场的变化情况，并给出了换热器的传热系数。

Cities of the desert region in the North such as Jaisalmer, Jodhpur, towns such as Srirangam in Tamil Nadu evolving around the temple as nucleus, the stepped wells of Gujarat, the vernacular architecture of the warm, humid area of Kerala- all these are unique in their response to socio-cultural and geographic context.

在北部地区的沙漠城市，比如贾沙梅尔，焦特布尔，泰来尔纳德邦：里面的城镇斯里兰格姆，周围展开的庙宇就像核子一样，戈加瑞的阶梯，本国的温暖，潮湿的喀拉拉邦的建筑——所有这些都独特地在社会与文化上，以及地理位置上都是相适应的。

As the intense surface heating sets up a steep lapse rate, a small circulation is formed when the surrounding air rushes in to fill the area of the rising warm air.

由于激烈的地面加热建立了一个陡峭的递减率，是一个小流通时形成蔺周围空气中，以填补该地区的暖空气上升。

The Lenape were loosely organized groups that practiced small-scale agriculture in order to increase their largely mobile hunter-gatherer society in the region surrounding the Delaware River, the lower Hudson River, and western Long Island Sound.

One will be connecting to those regions within a 200-400 mile radius that host a light earth dream and expanding this dream to one's home, office, neighborhood and the open space surrounding oneself.

你将连接到拥有地球光明梦想的半径为200-400英里的地区，并将这个梦扩散到自己的家、办公室、邻居，以及自己周围的开阔空间。

In spring, the wind field around Korea was mainly a northwesterly flow, while in summer it was west-southwestern flow. This fact leaded sand aerosols of the northern part of China and Mongolia and industrial aerosols of the eastern part of China to be transmitted to Korea well.

春季在韩国周围的风场主要有西北气流，在夏季有西-西南气流，兼有利于中国北部和蒙古国频繁发生的沙尘以及中国东部工业地区出现的高值气溶胶粒子传输到韩国。

Based on the shortest path matrix of 20 cities, we have quantitatively evaluated the highway network development level of the region by the accessibility index, extension index, conglomeration index, and etc. The result shows that in the space structure the highway network development level is a "core-margin" model. The cities with higher accessibility indexes gather around Zhengzhou City, while those with lower ones distribute in the margin. The order among conglomeration index is accordant to that of accessibility index.

以通达指数、伸展指数、趋中指数等为衡量指标，以20个入网城市的最短路径矩阵为基础，对中原城市群区域高速公路网络的发育程度进行定量评价，结果显示：中原城市群高速公路网络在空间格局上呈现明显的"核心－外围"模式，通达指数最高的城市集中在中心城市郑州周围，较低的城市分布在外围地区，且趋中指数排序与通达指数排序相吻合。

Bred in the areas around the equator, this protozoan proves very inactive out of the tropical zone.

这种在赤道周围繁殖的原生物，在热带地区以外的地方是极不活跃的。

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

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。
