| 3. | The first half was whisker - close , the lakers taking a 60 - 59 lead as the teams rattled off 10 lead changes
上半场比赛双方打得非常激烈，两队比分领先交替变化了10次，最终湖人60比59领先结束半场。 |
| 4. | This button , the world scout emblem which it contains , and any variations of these two items , are legally protected
这个有世界童军标志，其中包含了世界童军总部及会员国交替变化的按钮被合法地保护著。 |
| 5. | Patent claims of decreased dependence of nitrogen release rate on soil moisture , and soil variations from wet to dry are promising
这一专利声称该包膜可以减少土壤湿度及土壤干湿交替变化对氮素释放的影响，是很有价值的。 |
| 6. | Because frequency - shift signal is a kind of modulation signal , it ' s waveform is two ac sine signal of alternating i . e . upper frequency and lower frequency which was generated by low frequency modulating middle frequency
由于移频信号是一种调频信号，其波形为低频信号调制中心载频信号后产生的低端载频（下边频）和高端载频（上边频）两个交替变化的正弦交流信号。 |
| 7. | Thirdly we introduce the superlattice model with alternating site energies which is more complicated than the simple tight - binding model , and moreover we explore the influence of the alternating diagonal term in hamiltonian on the quasi - energy bands and dynamics
接着引入更为复杂的格点能交替变化的超晶格模型，并在此基础上考察了hamiltonian中交替变化的对角项对准能谱与动力学的影响。 |
| 8. | 7 the investigation of the thermoeconomic performance of an existing facility used for thermal fatigue experiments of aircraft canopy reveals the possibility and practicability of taking measures to improve it significantly . a piping system with alternative variation of flow temperature exists in this facility
对一现行的飞机座舱盖热疲劳试验系统? ?即流体温度升降交替变化的管路系统，进行了热经济行为的研究，揭示出它具有潜在与可行的重大改进方向和途径。 |
| 9. | The sequence of two patterns presence is changed alternately , that is , one pattern will appear at the second pulse of total pattern in this half cycle if it appears at first pulse in last half cycle . the stability of square pattern was studied by considering the interaction among the wall charges . the discharge moments of individual filament alternate from long one to short in the square pattern , which can been explained by using the breakdown and quench model through considering the wall discharge accumulated on the dielectric layers
实验研究了正方网格斑图与混合气体的比例及外加电压的关系，给出了班图类型随上述条件变化的相图；实验采用光学方法对正方网格斑图进行了时空动力学测量，发现正方网格斑图是由两套正方网格斑图相互嵌套而成，其中一套的微放电丝位于另一套正方形单元的中心，这两套微放电丝交替进行放电；考虑到壁电荷之间的相互作用，研究了正方网格斑图的稳定性；实验发现正方网格斑图的微放电丝放电时间间隔是长短交替变化的，考虑到电介质表面积累的壁电荷的作用，使用击穿?熄灭方程很好的解释了该现象。 |
| 10. | In loess plateau areas , dry and varied climatic condition was the main reason that resulted in the instability of soil moisture in surface layer . and because of the bad soil pedality and pore continuousness , the water in soil deep layers was difficult to supplement for that in surface layer . so , soil moisture of surface layer varied commonly and strongly
黄土高原地区干燥、复杂多变的气候条件导致该区土壤表层一定深度的湿度随时空变化非常剧烈；而且，该区土壤的结构性和孔隙连续性都比较差，深层土壤水分难以到达表层，使得土壤表层处于经常性的干湿交替变化过程中。 |
