Based on hypercycle theory, this paper analysis the relationships of teacher and student, intrinsic cognitive schema of student and explicit impartment, sports theory and technique, point out that hypercycle manner will combine all factors of sports teaching system more close and bring creativity, so lead sports teaching system evolve from simple to complex, from disorder to order ceaselessly.

基于超循环理论，分析了体育教学系统中教师与学生、学生原有认知图式和外在传授、超循环与创造性以及拟种进化与教学突变之间的内在关联关系，指出超循环的组织形式能够将体育教学系统中的要素更为紧密的耦合在一起，互利合作、协同进化，带给体育教学系统以突变性为特点的创造性，从而引导体育教学系统不断实现从简单到复杂，从无序到有序的自组织演化。

WANG Zhi-yi, CHEN S, YANG C HSchool of Civil Engineering and Architecture, Zhejiang Sci-Tech University, Hangzhou 310018, ChinaAbstract The cross defrosting cycle was presented in which one air side heat exchanger defrosts by switching over the corresponding four-way valve and the others operate normally.

摘 要：采用四通换向阀换向逆循环除霜，风冷热泵机组系统压力波动剧烈而产生比较大的机械冲击，频繁启动压缩机，影响室内的舒适性与压缩机的寿命，针对逆循环除霜的缺陷，提出了交叉除霜循环的原理和过程。

Notice that the body of the function, just like the body of the loop before, is indented, and since there is a loop inside of our function, the body of the loop is indented again.

注意这个函数的内容，刚好和前面的循环一样是缩进的。并且之后在我们的函数里也有一个循环，循环的内容再次缩进。

Ericsson cycle provides the maximum efficiency at a certain temperature ratio, and the performance of any other thermodynamic cycle can be got by revising the performance of Ericsson cycle with component-perfection coefficients and cycleperfection coefficient.

该公式有很强的功能，可以估算循环的热效率、比功、水气比、极限效率、各设备性能对循环性能的影响以及采用再热手段后循环的性能，而且具有很高的精度，热效率与精确计算相比相对误差在0.5％以内。

Presents the comparison between the thermodynamic performance of oil-burning closed STIG cycle and integrated gasification closed STIG cycle and analysis of the influence of reheating on efficiency of the two cycles and concludes that for IGCSTIG cycle, reheating can improve the efficiency only at lower inlet temperature of turbine and higher pressure ratio.

给出了燃料改用煤气后，燃油的与燃煤气的闭式注蒸汽燃气轮机循环的性能比较，同时分析了两循环分别采用一次中间再热后，再热措施对两循环热效率的不同影响。

With reforming ratio increasing,the maximal temperature and thermal efficiency of theory cycle is increasing,but the maximal pressure would be decreasing with reforming ratio increasing due to influence of moles.5 Kit experiment results of RE compared to that of hydrous-ethanol vapor engine are studied.

随着重整率的提高，理想循环的最高温度逐渐增大，由于分子体积变化系数的影响，循环最大压力随着重整率的提高逐渐下降；随着重整率的提高，循环热效率逐渐增加。5对比分析了RE发动机和VE发动机台架试验结果。

The Bucher diagrams of the Carnot cycle are used to present vividly three-heat-source cycle s.
