交替

Is precisely this kind happily with painful taking turn, only then causes the life to appear so colorfully!

正是这种欢乐与痛苦的交替，才使人生显得如此多姿多彩！

In commensuration case, firstly carbon nanotube slides on graphite, then switches between sliding and rolling due to the periodic change of atomic configuration during the motion.

结果表明：在公度条件下，碳纳米管先在石墨基底上滑动，动能降低到一定值后出现翻转、滚动、滑动交替进行的现象。

For example, at 250 ℃ steam valve, the use of asbestos packing and co-lead by alternative Diego, the situation would reduce the steam leakage; some valves, medium constantly changing, such as the asbestos packing and Teflon tape common use, seal it better.

例如，在250℃蒸气阀门中，用石棉盘根和铅圈交替迭合，漏汽情况就会减轻；有的阀门，介质经常变换，如以石棉盘根和聚四氟乙烯生料带共同使用，密封效果便好些。

However, attempts at these alternative methods have proven uncompetitive compared to a system based on compressed hydrogen gas.

不过，在这些试图做交替法已经与一个基于压缩的氢气体的系统相比证明uncompetitive。

As with Lully's stylization and organization of the opera, the concerto grosso is built on strong contrasts- sections alternate between those played by the full orchestra , and those played by a smaller group.

与吕利在歌剧方面的系统性和组织性相比，克莱里的大协奏曲建立在强烈对比的基础上--是由更小规模组全弦乐演奏的交替。

Decisions regarding trade-offs between the concreteness of learning experiences and time constraints have to be made continually by the instructor .

关于具体和抽象经验如何交替使用，多年来一直有不同的观点。1946年，戴尔提出了著名的"经验之塔"。

The fuzzy flow-awareness with the load state information can identify different services congruously in path. And the dynamic priority fairness scheduling algorithm based on fuzzy flow-awareness will adjust the priority of forwarding dynamically between streaming flows and elastic flows by changing the threshold of priority queue. The algorithm emphasizes the fairness of scheduling under the light load and the priority of real-time applications under the heavy load for their delay requirements.

与链路负载状态相关的模糊流感知能够实现路径上的一致性业务区分，而基于模糊流感知的动态优先公平调度算法通过调整优先队列负载门限在流式流和弹性流之间实现转发优先权的动态交替，在链路轻载时实现不同流间的相对公平调度，在链路重载时则强调实时业务的绝对优先权以保证其时延要求。

The optimum carbon source of the pathogen for the hypha growth and conidiophore bearing was amylomaltose, the optimum nitrogen source was yeast extract and the alternation of light and darkness could promote the hypha growth.

菌丝生长及产孢的最适碳源为麦芽糖，最适氮源为酵母膏，光暗交替有利于菌丝的生长。

The most feasible temperature for mycelial growth is 28~3TC and for conidial germination is 31~34癈; The most fitting pH for mycelial growth and conidial germination is 5~6;12 hours light and 12 hours dark by turns is benefit for mycelial growth, while light and dark have no influence on conidial germination, but ultraviolet radiation can kill the conidium?

其中最适于病原菌菌丝生长的温度为28～31℃，pH为5～6，12小时光暗交替有利于菌丝的生长。最适于病原菌分生孢子萌发的温度为31～34℃，pH为5～6，光照对孢子萌发没有显著影响，紫外光对孢子有杀伤作用，随着紫外光照射时间的增长，对孢子的杀伤力加大。

Magnetotherapy - is a method of healing by alternating low-frequency and constant magnet field.

磁疗-是一种愈合交替的低频和不断的磁场。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
