It has a period of about 6~11 min. The vortices have a scale of about 5000 km×1400 km, and move earthward at the speed of 15~25 km/s.

所有5个涡流的旋转方向都为顺时针方向，旋转周期约为6~11 min。

The results show that the microstructure of ventra1 scale for python was composed of micro-convex and plank structure that was periodically arranged, it was mensurable and could be described by 9 characteristic parameters. Its surface was different in their forward and backward lean angle. The frictional coefficient of the ventra1 scale had closely relationship with moving direction, it decreased with the increasing load. The value of the frictional coefficient was about 0.07. The frictional coefficient while python moved backward and laterally were equal, and that was 33% more than that moved ahead. The frictional force of the ventra1 scale surface was caused by mechanical tooth function of micro-convex, acting intermolecular force and material's elastic hysteresis. The difference of forward and behind bevel for micro-convex was the anisotropy reason of frictional force.

结果表明：腹鳞表面的微观结构由指状微突体和板结构部分周期排列而成，其结构可用9个特征参数定量描述；腹鳞表面摩擦力由分子作用力、表面微突体的犁沟力、楔形作用力以及材料弹性滞后共同引起；腹鳞表面的摩擦系数在0.07左右并与运动方向有关，摩擦系数随载荷增加而减小；后向运动及左、右侧向运动时摩擦系数基本相等，比前向运动时高33%左右；腹鳞表面微突体不同方向上倾斜角度的差异是引起摩擦各向异性的主要原因。

The experimental results showed that the elastic modulus and shear modulus decreased with the increasing of temperature in general.

实验还发现材料在结晶方向和垂直于结晶方向的弹性常数和蠕变特性等力学性质具有很大的差异。

Structure form adopts converse triangle beam double-hole connection welded by general electric trolley wall plate and steel plate, connection shaft, triangle beam bottom is connected with girder by nut and thrust bearing, triangle beam could rotate 360 degrees horizontally, thus realize whole set electric trolley horizontal rotation, largely reduce curve track curvature radius of electric hoist traveling mechanism.

描述： 结构形式采取通用电动小车墙板与一个钢板和连接轴组焊的倒三角形吊梁双孔连接，三角吊梁下面通过螺母及推力轴承与一个横梁连接，三角吊梁相对横梁可在水平方向做360度旋转，从而实现电动小车的整体水平方向转动，大大减小了电动葫芦运行机构弧形轨道曲率半径。

In this paper, a new medical impedance imaging modality (Magnetic resonance electrical impedance tomography-MREIT) is first introduced, including its mathematical theories and the reconstruction algorithms. Then its application in early breast cancer detection research is introduced in detail. Finally, its future research direction and major problems are summarized.

Using the latest linear way and imported belts ensures stability and durability of the embroidery frame.

采用最新直线导轨设计及进口皮带，确保花架稳定性及耐用性，保持刺绣精确度。X方向采用3条皮带设计（680mm及750mm机专用），Y方向采用5条皮带设计，确保刺绣产品在花架任何位置的稳定性。

It indicates that the extinction capability and concentration of bubble solvent can seriously influence the light absorption in some wavebands, bubbles can change the direction of light propagation and reduce the energy density, the transmission intensity and light energy decrease rapidly with the increase of times that the light passes through the bubbles, and bubbles′ floating nature can cause the uncertainty in the emergent ray direction and energy distribution.

结果显示：泡沫溶液的溶质/溶剂的消光能力、浓度等对特定波段光波的吸收产生关键影响；泡沫通过改变光线的传播方向，大大分散出射光线的能量密度；随着光线穿过泡沫液膜界面的次数增多，透射光强迅速衰减，透射能量迅速下降；其漂浮运动还将导致出射光线方向和能量密度分布的不确定性。

Therefore, to advance the study on innovation of urban planning institution, the emphases should be in-depth analysis on the existent specific institutional arrangements, and reflection on theoretical methodology, nuclear concepts and logistic series of the institution system. The starting point of urban planning institutional innovation could base on the existent planning operational system, such as development planning, distribution planning and specific construction planning etc., or relate to urban construction and other relevant institutional arrangements. However, the emphasis should be establishing the mechanism of distributing, harmonizing and balancing different interests, rights.

城市规划制度创新可以按照城市发展规划、布局规划和具体建设规划等原规划运作体制及系列，以及与城市建设口其他相关制度安排相联系等不同方向行进；也可以从1980年代有关专家就已经提出的、近期国家发改委等有关部门正在积极研究创新的发展规划、布局规划、建设规划等分类规划与综合规划相结合的方向行进；但是制度创新的重点应放在对利益、权益的分配、协调与平衡机制的构建上。

However, increasing temperature also enlarged the dissociation free energy barrier, which in turn resulted in increased desorption of adsorbed precursors.
