The original symmetry point and have seriously deviated from, if you want to make a balance between the development of the city, there are two approaches, one is the original economic development of backward areas, for example, to Nancheng huge investment, it's rapid economic growth; also There is a way to move the center to make it balance, if it is still definitely in line for Chang'an Street, Beijing should not balance the development is therefore imperative to the city centers to China.

原来的对称点和已经严重偏离，如果您想之间的平衡发展的城市，有两个办法，一个是原来的经济发展落后地区，例如，南城巨额投资，经济的快速发展增长；也有一种方法可以移动中心，使之平衡，如果它仍然是绝对排在长安街，北京不应该平衡发展，因此必须在城市中心，中国。

Because the above surface breaks the point symmetry of spherical dome, the system may introduce dynamical aberrations depending on Regard of View and Field of View, which is characterized by large tilt and large eccentricity.

If the step of the linear system question is not very high, direct solving method is better; if coefficient matrix of the linear system question is not regular and large-sparse matrix , direct solving method does not settle the storage question.

而在求解线性方程组的许多实际问题中，尤其在偏微分方程的差分方法与有限元方法求解问题之中，方程具有重要的特征，一是多为大型稀疏矩阵；二是满足一些条件如对称正定、对角占优等，这使迭代法得到广泛的应用。

Right now the nurse answers with gentle language, patient manner sucks phlegmy necessity and importance to patient and family member specification, and the serious consequence that rejects to suck phlegmy likelihood to bring about, and signal patient and gentleness of movement of family member operation, at the same time directive and sober patient cooperates to may decrease those who suck phlegmy place to bring is unwell, cooperate in order to obtain what the patient reachs a household. Whether do the 5 distances that check tracheal spile to be apart from fore-tooth have fluctuant reach auscultation sound of double lung breath is symmetrical. Sound of breath of 6 auscultation double lung, in order to judge the place of phlegmy fluid. The 7 patients as a result of tracheal spile, what aeriform exchange does not pass nose pharynx ministry is wet change, make inside tracheal spile drier, reason should time do pulverization inspiratory 2 / D~4 second / D, arrive in order to rise the wet path that spend energy of life, avoid the end with phlegmy scabby fluid.

此时护士应以暖和的语言，耐心的态度向病人及家属说明吸痰的必要性和重要性，以及拒绝吸痰可能导致的严重后果，并示意病人及家属操作动作轻柔，同时指导清醒病人配合可能减少吸痰所带来的不适，以取得病人及家属的配合。5检查气管插管距门齿的距离是否有变动及听诊双肺呼吸音是否对称。6听诊双肺呼吸音，以判定痰液的位置。7由于气管插管的病人，气体交换不经过鼻咽部的湿化，使气管插管内较干燥，故应定时做雾化吸入2次/d~4次/d，以起到湿化气道、防止痰液结痂的目的。

In the view of ability difference, this paper studies the asymmetric mechanism of collusion-proof, and proves that: when ability difference is symmetric information, collusion stake can be distributed on this common information, thus ability difference cannot result in server benefit conflict between agents to make the coalition c...

本文在强调代理人能力差异的基础上，建立防止合谋的非对称机制。并证明当能力差异为公共信息时，合谋收益就可以据此公共信息进行分配，因此双方的能力差异并不足以使代理人之间产生严重的利益冲突并导致利益集团的崩溃，从而无法防止合谋的发生

The traditional mean shift algorithm requires a symmetric kernel, such as a circle or a rectangle, and assumes that the target's scale is symmetric during the course of tracking. The pixels are used on the edge as the samples, about 5% to 10% of the total pixels in the kernel.

与采用对称核函数的均值迁移目标跟踪算法相比，采用目标边缘点作为核函数中的样本点，参与计算的样本点为核窗口中样本的5%~10%，使图像处理速度达到了50帧/s以上，满足了实时跟踪的要求。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.
