多常

In the computation of aerodynamic forces, the present work is based on the work of Morino et al., but the following aspects are improved:(1) In computing the steady transonic aerodynamic load, the steady transonic nonlinear integral equation is solved by relaxation-iteration method in this thesis, instead of solving the time dependent transonic nonlinear integral equation, so that the computing time is saved greatly;(2) The influence coeifficients represented by volume integral are transformed to surface integral by using the Gaussian Theorem, so the analytical form of these coeifficients can be obtained and this leads to be more convenient to analyse and compile computer program;(3) The shock capturing method is used in every time step in present work, no shock moving term is added in the integral equation, so that it is more convenient and simpler to treat.

在气动力计算方面，本文基于Morino等人的工作，作了如下几方面的改进：（1）在计算定常跨音速流场（作为非定常绕流计算的初场）时，本文采用松驰迭代法直接求解跨音速定常非线性积分方程，而不是采用时间相关法求解非定常非线性积分方程，这样大大节省了计算机时；（2）将以体积分形式出现的影响系数化为面积分，并获得解析公式，这样便于分析和编写程序；（3）对运动的激波，本文通过在每一个时间步长上采用激波捕捉法而得到，而不是在积分方程中附加激波运动项，因而处理起来简单方便得多。

In order to obtain more general solution of second order linear differential equation with constant coefficients, which is important in theory and practice, on the basis of knowing a special of the second order linear differential equation with constant coefficients and by using the method of variation of constant, the second order linear differential equation with constant coefficients is transferred to the reduced differential equation and a general formula of the second order linear differential equation with constant coefficients is derived.

为了更多地得到理论上和应用上占有重要地位的二阶常系数线性非齐次微分方程的通解，这里使用常数变易法，在先求得二阶常系数线性齐次微分方程一个特解的情况下，将二阶常系数线性非齐次微分方程转化为可降阶的微分方程，从而给出了一种运算量较小的二阶常系数线性非齐次微分方程通解的一般公式，并且将通解公式进行了推广，实例证明该方法是可行的。

Such as inflammation of joints, the lower leg, such as chronic venous insufficiency lead to long-term sustainability of the skin caused by congestive hairy; hyperthyroidism in Pretibial myxedema patch Department often long acuminatum out; hypothyroidism and limbs of children in the back outside a large number of hair growth; children with viral encephalitis and inter-brain barrier after mumps-induced systemic hairy; head injury, especially after the children more prone to hair; children with primary malnutrition or enteropathy, or other malabsorption, or severe infections caused by malnutrition could rise to a large number of multi-body hair; anorexia nervosa patients in the face, trunk and upper limbs have more hair grow; infant limb pain patients in the limbs, face, trunk and more hair; dermatomyositis patients, mainly in children can be located hairy forearm, leg and temporal, but also a broader scope; Berordinelli syndrome, that is, growth and maturity accelerated from an early age, and accompanied by malnutrition and intestinal muscle atrophy, common hepatomegaly and high blood fat, the skin of patients with rough, often hairy; addition of certain drugs such as streptomycin, such as cortisone can cause iatrogenic hairy; some women as a result of adrenal, ovarian and other diseases caused by increased androgen can also result in more hair.

比较有趣的是观察洋基要多常被迫将Posada放在这里。

Every one of us is an important part of the great work. As Xu Sanduo said in the Soldiers Sortie: this is a very meaningful job!

所以，我们大家正在做的工作就像《士兵突击》中许三多常说的：这样做是有意义的。

Mainly Lauraceae, Fagaceae, Theaceae, magnolia Branch, Division of Hamamelidaceae evergreen broad-leaved trees such as the composition of the shrub layer are found to evergreen species, community structure is more complex.

The clinical characters of oligodontia concluded from this study are following:(1) There is significant difference that more teeth absent and more existent teeth anomalies in patients of oligodontia/S group than in patients of oligodontia/I group, and the peg-shaped upper lateral incisor is the most frequently affected teeth with shape anomaly.(2) Both of the two groups have no significant differences in number of teeth missing between maxilla and mandible as well as that between left and right side.(3) The distribution of teeth missing is bilateral symmetry in both groups, but the frequency of teeth lost are different: excluding the third molar, in oligodontia/I group, the lower second premolar is the most frequently congenitally missing tooth followed by the upper lateral incisor, while in oligodontia/S group, the most frequently missing teeth are mandibular canine and maxillary lateral incisor. Nevertheless, the first molars are the most stable teeth in both groups.(4) In oligodonita/I group, the mean mesiodistal dimensions of all type of existent teeth are significantly smaller than normal value. It is implied that oligodontia is not an isolated phenomenon, but is related to a complex of other dental changes.

对于口腔多个恒牙先天缺失的临床特点有以下初步结论：(1)综合征型先天缺牙患者较单纯型先天缺牙患者恒牙缺失数目更多，平均分别为23.9个和14.9个，且现存牙齿有更多的形态异常，分别为7／10例（70％）和6／22例（27.3％），其中最常见的是上颌侧切牙畸形；(2)两种类型的多个恒牙先天缺失患者的缺牙数目在上下颌及左右侧之间均无差别；(3)两种类型的多个恒牙先天缺失患者在缺失牙位上均呈对称分布，但在具体牙位上有所差异：不计第三磨牙，单纯型先天缺牙最常缺失的牙位是下颌第二双尖牙、其次为上颌侧切牙；而综合征型先天缺牙最常缺失的牙位是下颌尖牙和上颌侧切牙；无论何种情况，第一磨牙均为牙列中最稳定的牙齿；(4)在单纯型先天缺牙患者中，现存恒牙的牙冠宽度较国人正常值偏小，差异显著，提示牙齿形态与多个牙先天缺失有一定相关性。

I have me my summer vacation in a town last year.since whose are there.some of my relations,there have a good view for the mountain and river,I think it's a great place be to rest,one day when i ride my bike on the small path,this river catch my eye for very clearly but like very deeply,becauese i can't see the end of the water,then.some chap shouting make me look at,they catch a a short boy and thow he in the water with a heavily,waiting for a moment yet the boy not up the water,i'm very worry and jumping in the river,i want float out but some watergrass be enteine my leg and the body is deeper at every movey,i don't know past how long time,i feeling one small hand help me break up the watergrass and push me to the surface of the rive,after that i just kown they are hvae a playing who can sit in the swim and make a long time in deep water,but i want cry for the joking,becauese i couldn't swim but i have a forget.

去年我在一个小镇上度暑假，因为那里有我的亲戚，我认为那里有好山好水是一个静休的好地方。一天当我在小路上骑着自行车时，一条非常清澈但好像也挺深的小河吸引了我的视线，因为我好像看不到河的底端，这时，一些小孩的叫喊声因起了我的注意，他们抓住一个矮小的小男孩然后重重的扔进了水里，待了一小会这个男孩没有露出水面，我非常担心就跳进了水里，我想浮出来，但一些水草缠住我了的腿，我每动一动身体就会越往下沉，我不知道过了多常时间，我感觉有一双小手帮我弄掉腿上的水草并往水面推着我的身体，后来我才知道他们是在玩看谁在水底呆的时间长的游戏比赛，但我对于着样的笑话想哭因为我忘记自己了不会游泳。

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。
