Based on the background information on the part of the existing strategy adopted by the Beijing Gas Group, this paper conducts a detailed analysis of strategic issues of this group company by using such analytical tools as SWOT Matrix, Boston Matrix and Portor's Five Forces Model. The author discusses the status in quo of global gas market and domestic market, the internal environment of the group company, and the structure of gas industry. The major strategic problems of the group company are summarized on the basis of above-analysis, including the obsolete thoughts of decision makers, the weak management system of human resources, the deviation on building corporate culture, and the teetering on information processing.

The invention relates to a dynamic matrix control system of high-purity distillation, which comprises distillation tower, intelligent checker, DCS system, superior host, and on-site bus, while they are connected. The control system uses tower product group as the object variable, and the reflux ratio and reboil ratio as control variable; the superior receives history temperature and pressure data from the DCS real-time database, via the predict control and dynamic matrix controller, to obtain the output values of present controller as reflux ratio and reboil ratio, then feedback said two values to DCS system, to function the distillation object. The invention can confirm the high-purity stable operation, with better dynamical control.

The relationships between the eigenvalues of Jacobi iteration matrix and the block AOR iteration matrix make a very important role in our analysis. Then we prove some sufficient conditions for the semiconvergence of the block AOR method.

利用块AOR迭代矩阵和相应的块Jacobi迭代矩阵的特征值之间所存在的关系，我们证明了求解奇异p-循环线性方程组的块AOR迭代法半收敛的一些充分件。

The results indicated that with solution time increasing,Mg_(17)Al_(12) phase was dissolved into the Mg matrix and Al_2Ca phase became thinner and shorter,then gradually broken and began to spheroidize;with aging time increasing,Mg_(17)Al_(12) phase was precipitated from the Mg matrix as the form of small particles and Al_2Ca phase was stable and its shape and quantity change...

随着时效时间的增加，Mg17Al12相以细粒状从过饱和的镁基体中析出；而Al2Ca相比较稳定，其数量和形状变化极小。固溶处理后，合金硬度和拉伸强度有所下降；时效处理后，合金硬度增加到峰值后下降，拉伸强度略有升高。固溶、时效处理后轧制AM50和AM50+1Ca镁合金的塑性有所增加；而轧制AM50+2Ca镁合金固溶后塑性有所增加，时效后塑性有所下降。

Organic matrixs coming from cells play role in nucleation, growth, morphology, polymorphology of inorganic materials. This control of organic matrixs are mainly behaved by the interfaction between organic matrix and inorganic materials .The processing of organic matrix controlling inorganic material is called as molecular recognition. The mechanism of organic-inorganic molecular recognition contains three facts such as electrostatic attraction, lattice geometry matching and stereochemical complimentary.

Whereas osteoporosis is unassociated with bone pain, osteomalacia has been associated with isolated or generalized bone pain.39,40 The cause is thought to be hydration of the demineralized gelatin matrix beneath the periosteum; the hydrated matrix pushes outward on the periosteum, causing throbbing, aching pain.7 Osteomalacia can often be diagnosed by using moderate force to press the thumb on the sternum or anterior tibia, which can elicit bone pain.7,40 One study showed that 93% of persons 10 to 65 years of age who were admitted to a hospital emergency department with muscle aches and bone pain and who had a wide ariety of diagnoses, including fibromyalgia, chronic fatigue syndrome, and depression, were deficient in itamin D.41

然而，骨质疏松症与骨痛无关联，而软骨病则与局部性或全身性骨痛有关。其原因被认为是骨膜下已去矿质化的胶原基质上发生的水合反应，水合的胶原基质在骨膜上向外扩张，引起阵痛。软骨病可通过以拇指适度挤压胸骨和胫骨前方以引起骨痛感。一项研究显示10岁到65岁中有93%的人向医院急诊室承认有肌肉疼痛和骨痛症状，他们还有一些其他症状包括纤维肌痛、慢性疲劳综合征、抑郁等，该研究显示他们都缺乏维生素D。本人已认领该文第9、10两部分，48小时后若未提交译文，请其他战友自由认领。本人已认领该文11、12部分编译，48小时后若未提交译文，请其他战友自由认领。本人认领第十三部分，48小时内交稿请战友纠错！
