Based on this principle, the mathematical model of an exothermic reactor is established to caculate Exothermic reator length L corresponding to reation temperature T, reation temperature T corresponding to ammonia mole fraction y and the average internal reactor wall temperature Tave corresponding to exergy output Enet and thermal power output Q. The curves of L-T, T-y, Q/Enet –Tave are drawn with the caculated date which can directly reflect the influence of reactor inlet gas temperature and reactant flow rate on ammonia synthesis reaction for the reactor under the conditions of definite design pressure and hydrogen/nitrogen ratio. Furthermore, the design parameters to realize maximum exergy output and thermal output are presented.

The results showed that small-scale gaps were the predominant types of disturbance. The average gap density was 12.5 km^(-1). The distribution pattern of gaps was aggregated on south facing slopes and was approximately homogeneous on north facing slopes. Conifer trees were the primary gap-makers in this forest that was dominated by Abies faxoniana, Tsuga chinensis, Betida utilis, both in abundance and diameter rank. The decay class distribution of gap-makers indicated that the mode of gap formation and gap-maker species changed with age of the forest; the contribution of conifer species to gap formation decreased with time and broadleaf species increased.
结果表明:l本区以小型林隙干扰为主,林隙平均密度为12.5个km^(-1),林隙的分布格局在阳坡和山脊为集聚分布,阴坡近均匀分布;林隙形成木以针叶树为主,岷江冷杉、铁杉和糙皮桦在形成木的数量和径级组成上均居前列。2林隙形成木的腐烂等级分布揭示出林隙形成木的形成方式和种类组成均随时间变化。

In chapter 2, we focus on derivation of the tortuosity models for flow of Newtonian incompressible fluid in two- and three-dimensional porous media with spherical, cubic and plate-like particles by applying the geometrical method. We first present the ideal geometrical models of porous media to show the ideal and representative streamlines based on the assumption that some particles in porous media are unrestrictedly overlapped and hence of different configurations, then the average tortuosity is derived by geometrically and weightedly averaging these representative flow paths.

During this period, the West Germans made sacrifices in trying to help rebuild the rickety economy in the east. Unemployment in the west rose from 5.7% in 1991 to 8.4% in 2003, with the number of enterprises declaring bankruptcy jumping from 8443 to 29,700 in the same period. The average annual burden placed on each wage-earning citizen of the west to help rebuild the east almost doubled from 3,993 Euros in 1991 to 6,796 Euros in 2003. This created a great burden on West German finance. Many West Germans, from all sectors, feel that reunification has become a bottomless pit, and say that the cost has been huge and there is no estimate of how much higher it will go.
在此期间为求重建摇摇欲坠的德东经济而付出天价钜资的德西财政亦大举失血,失业率从1991年的5.7%上升至2003年的8.4%,而宣告破产的企业总数则从1991年的8443家迅速攀升至2003年的29700家,德西人民每人每年平均为因应德东重建计划而负担的金额,从1991年的3933欧元快速上升到2003年到6796欧元,足足上涨近一倍,从而造成了德国财政极为沉重的负担,此种代价几令德国各界人士大感吃不消,致而喟叹:「两德再统一的代价太过钜大,投入的金额根本无从估计起」。

From the sales situation, existing homes sales in the main polarization obviously, as follows: low-end hot-selling item, such as Yue Min homes,青塔East, the Point Park real estate without any publicity, relying on word-of-mouth communication, a low price to win, the average monthly turnover of around 50 sets; midrange sales sluggish: Most of the projects has been a very long time into the market, such as ZHUANG Garden (6 towers) began selling in 1999,盛鑫homes (4 Building towers) into the market in 2000 and so on, have entered the current phase of existing homes, but not satisfactory.
从销售情况,现有住房销售的主要两极分化明显,具体情况如下:低端热销的项目,如乐民家园,青塔东,起点园房地产没有任何宣传,依靠口碑传播,以较低的价格取胜,平均每月的营业额约为50套;中档销售疲软:大多数项目已经很长的时间进入市场,如庄花园( 6塔楼)开始销售在1999年,盛鑫家园( 4楼塔)到2000年的市场等,已进入本阶段的现有住房,但不能令人满意。
