In this paper, the equations of motion of vortices in baroclinic atmosphere are derived in the light of classical hydrodynamics. Six factors determining the motion of vortices are discussed. Physical interpretation and some comments are given to the well-known steering principle. Application of these equations in the forecasting of the motion of typhoons are illustrated by three examples, and the results are better or as well as those of the synoptic forecasts.

In this paper, the equations of motion of vortices in baroclinic atmosphere are derived in the light of classical hydrodynamics. Six factors determining the motion of vortices are discussed. Physical interpretation and some comments are given to the well-known steering principle. Application of these equations in the forecasting of the motion of typhoons are illustrated by three examples, and the results are better or as well as those of the synoptic forecasts. Possibility and limitation of their application to the motion of middle-latitude vortices are also discussed.In the appendix, there are critical discussions of the role of the internal forces and the calculation of the amplitude and period of the meandering motion of typhoons in straight steering current.

The Regulation of braided stream with heavy sediment load calls for a complete change in river regime of a stream course running hundreds of kilometers long. This is only possible by modifying the hydrograph and the sediment production rate of the watershed and by changing the boundary conditions of the stream channel. The construction of reservoir in the upstream basin upsets the equilibrium conditions of the river downstream of the dam, and a change in regime is expected. The braided river, after gradually losing its wandering intensity, will transform into a meandering pattern. At the beginning of the adjustment, the shifting of the main current still exists. The channel will be deepened by the passage of water with much smaller sediment concentration. Yet, on the other hand, the recedence of the bank lines under the attack of the ever-shifting current tends to widen the channel. The eventual modification of the cross-sectional form of the degrading reach depends on the interaction of these two types of forces. At low and medium stages, it appears that the deepening of the channel has gained the upper hand. After the passage of a larger flood when the water overflows the flood-plain, a rapid widening of the channel will take place instead. In as much as the recedence of the bank lines is a threat constantly in existence, every effort should be made to cut down the flow released from the dam to a value smaller than the bankfull discharge of the downstream channel, and bank stabilization works must be started immediately after the completion of the dam. The control of the mean-water channel and the protection of the bank lines should be proceeded hand in hand, with the former as the main measure. It is proposed to modify the river course into a succession of smooth bends such that the thalweg will be fixed along the concave side of the bend and low sand banks formed on the other. By using a smooth curve to guide the flow, the jetties and training walls will be subjected to a force evenly distributed along the bend, and this is beneficial for their maintenance. The protection length of the concave bank depends on the radius of curvature of the bend and on the variability of the flow. According to the experiences obtained from one of the sandy rivers in China, the ratio of protection lengths upstream and downstream of the apex of the concave bank is 2 to 3. In the degrading reach, it is sufficient to stabilize the concave side of the bend only. In the transition and aggrading reaches, underwater jetties should also be built along the bank line at the lower half of the convex side of the bend.

在多沙河流上修建蓄水拦沙水庫以后,下游游蕩性河道将逐漸向弯曲性轉化.如下洩清水不超过下游河道的平滩流量,則河床将以下切为主;如水流继续不断漫滩,則河道将逐漸展寬。固定中水河槽是保护滩地,加速河道調整过程的重要途径,应尽量利用已有节点,增加节点数目,并逐步改善节点外形,使其具有曲度适当的弯道型式。文中根据多沙河流的經驗及模型試驗結果,对河湾平面尺寸、护岸导流工程的布置及結构进行了初步探討.

Transmission line theory is applied to the study of a system of uniform parallel coupled multi-strips, considering only the coupling of the nearest neighbors. It is found that there are three normal modes-the odd-even mode, the odd-odd mode and the even-even mode. By studying the influence of the length of the coupled meander line on the propagating mode, we find that when the length L is an odd-multiple of /4, only the odd-even mode can propagate; when L is an even-multiple of /4, only the odd-odd...

Transmission line theory is applied to the study of a system of uniform parallel coupled multi-strips, considering only the coupling of the nearest neighbors. It is found that there are three normal modes-the odd-even mode, the odd-odd mode and the even-even mode. By studying the influence of the length of the coupled meander line on the propagating mode, we find that when the length L is an odd-multiple of /4, only the odd-even mode can propagate; when L is an even-multiple of /4, only the odd-odd mode and the even-even mode can propagate. The image impedance and wave propagation in the coupled meander line of length 4 are discussed, and an approximate formula for calculating the characteristic impedance of odd-even mode, Z, is given. The matching of the edge strip and the input impedance of the coupled meander line of length. 4 are analysed. Finally , the calculation of the microstrip characteristic impedance with a ferrite substrate is considered.
