后循环的

Under the circumstance of satisfying the two necessary conditions of late-developing advantages, the potential advantage can be transformed into the motive force of development to propel the society forward and reduce the development gap between the early-developing countries. The process is a closed circle of damped oscillation. It can only turn into increasing oscillation circle with the consistent innovation and breakthrough so that the backward countries can exceed the early-developing countries.

潜在的后发优势在满足后发优势发挥作用的两个必要条件的情况下可转变为发展动力，推动社会向前发展，缩小与先发国家之间的发展差距，这一个过程是一个减幅振荡的闭路循环，只有在引进、消化的基础上不断创新、突破，才能打破单纯由后发优势导致的减幅振荡闭路循环，进入增幅振荡循环，后发国家才有可能超过先发国家。

In the spiral pipe heat exchanger exports terminal, the ammonia steam temperature has been heated up 85 ℃--95 ℃, by now, the ammonia steam had the 45kg-55kg/cm2 ammonia steam pressure, sent in the ammonia steam turbine through the constant temperature pipeline, impelled ammonia steam turbine revolving, led the generator electricity generation;After the ammonia steam makes the merit release energy, the temperature drop, the returns ammonia storage tank, passes through again adjusts the press pump to press into the spiral pipe-type heat exchangers to carry on the next circulation;Including the ammonia steam turbine entire ammonia steam road is becomes the independent closed cycle system, is isolates completely with the outside air;The ammonia steam only plays the carryhome and the shift energy role, in the electricity generation process does not consume the actuating medium, the stored energy carrier water also is only gets up the carryhome and the shift energy function,The waterway also is from becomes the independent closed cycle system, in the electricity generation process also the needless water consumption, through the actuating medium ammonia steam and the stored energy carrier water unceasing shuttle service, transforms through the heat interchanger the solar energy as the actuating medium ammonia steam heat energy and the kinetic energy,With the aid of the ammonia steam turbine heat - machine transformation function and the generator machine - electricity transformation function, has realized the solar energy hot - electricity entire conversion process, transforms continuously the solar energy into the electrical energy, power supply for foreign;The low temperature generating system must solve three big technical keys:One, the anticorrosion (has actuating medium has strong corrosiveness), two is Explosion-proof (Some actuating medium Can have the detonation with the air mix when divulging, controls warm malfunction, elevates temperature suddenly also can have detonation), three is guards against the revolution axis divulging

以太阳能低温发电系统为例，低温发电方法是这样进行的：以水作为储能载体的太阳能采集器将太阳能采集起来，将水温提升至85℃--98℃；用氨作为工作介质储于氨储罐及氨汽路中；采用螺旋管型热交换器；用调压泵将氨储罐中的氨汽压入螺旋管型热交换器的螺旋管内，用调压泵将携带太阳能的85℃--98℃的储能载体热水压入螺旋管型热交换器的螺旋管外壁空间进行循环式热交换，在热交换器的螺旋管出口端，氨汽温度已被加热到85℃--95℃，这时，氨汽具有45kg—55kg/cm2的氨汽压力，通过恒温管道送入氨汽轮机，推动氨汽轮机旋转，带动发电机发电；氨汽作功释放能量后，温度下降，返回氨储罐，再经调压泵压入螺旋管型热交换器进行下一次循环；包括氨汽轮机在内的整个氨汽汽路是自成独立的封闭循环系统，与外界空气是完全隔绝的；氨汽只起携带和转移能量的作用，发电过程中并不消耗工作介质，储能载体水也是只起携带和转移能量的作用，水路也是自成独立的封闭循环系统，发电过程中也不消耗水，通过工作介质氨汽和储能载体水的不断循环运行，通过热交换器将太阳能转化为工作介质氨汽的热能和动能，借助氨汽轮机的热—机转化功能和发电机的机—电转化功能，实现了太阳能的整个热—电转化过程，将太阳能源源不断地转变为电能，对外供电；低温发电系统要解决的三大技术关键：一是防腐（有的工作介质具有较强的腐蚀性）、二是防爆（有的介质泄漏与空气混合会产生爆炸，控温失灵，急剧升温也会产生爆炸）、三是防轴漏（汽轮机是动态旋转体，必须解决工作介质的防轴漏问题）。

Culture tender leaves in culture medium of MS+2,4-D1.5mg/L+30g/L suger+0.7% agar pH5.8 for 20 days in darkness at 25℃, and then subculture to induced Ⅱ-type calli. Use forceps cutting the tissue to nubble with 2mm2, and put the tissue into Agrodacterium tumefaciens LBA4404 liquid supplemented with AS 100mg/L,then, co-culture 3 days, resume 7 days in MS+2,4-D1.5mg/L+30g/L suger+500mg/L cef, take to MS+2,4-D1.5mg/L+30g/L suger+100mg/L cef+10.0mg/L kanamycin culture 20 days in darkness. After that to make it polarize in MS+30g/L suger+100mg/L cef+10.0mg/L km. The percentage of km resistant callus was reached max after infection for 45 min, the average is 29.66%. Simultaneity, tender leave callus are infected 5 min by A. tumefaciens liquid in different negative pressure, and kept on 15 min in Agrodacterium tumefaciens liquid without negative pressure. Then screen out resistant callus and obtain transgenic plants. When the negative pressure is -0.05MP the percentage of km resistant callus was reached max, the average rate is 37.5%.
