三次

It is the third major wave after the tradition of Intenet and web, as the third generation Internet.

它是继传统互联网、Web之后的第三次大浪潮，被称为第三代互联网。

So you mother cat cat dad sure to carefully deal with the situation of the kitten, convinced that they are not infected by any disease under the premise (a family environment to ensure that all food and sanitation, immunization has been kitten) can be stopped and fed canned To digest the bad meat, such as food, a milk-fed two pieces of Health, can be two or three times a day, so that one day the time will be the effect.

所以各位猫爸猫妈请一定要仔细对待小猫的这种状况，在确信没有染上什么病的前提下（家庭环境和食物都能保证卫生，小猫也免疫过）可以，停喂罐头和肉等不好消化的食物，一次喂两片乳酶生，一天两三次就可以了，这样有一天的时间就会见效了。

In order to design optimum nozzle for air-air missile solid rocket motor, the mass model of solid rocket motor, the nozzle specifice impulse model of solid rocket motor and the objective function are established. Five different type of nozzles are choosen lor calculation: Conical, parabolidal,two different arcs,quadiatic polynominal and cubic polynominal.

以两种空-空导弹固体火箭发动机喷管作为算例，为此，建立固体火箭发动机的质量模型，喷管的质量比冲模型和目标函数模型，选择五种喷管扩散段内型面：锥形喷管，抛物线喷管，双圆弧喷管，二次多项式喷管和三次多项式喷管，进行优化设计，利用优化理论，成功地完成了五个设计变量的优化问题。

In chapter three the performance and structure of components of oxygen probe were especially investigated. The Cr-Cr〓O〓 powder was overcome by treatments. The reason of occurrence of thermal peaks on the EMF curves was explained. A water glass based cement which high temperature insulation was around 10MΩ within 10 seconds at 1600℃ was developed for the use of oxygen probe. The effects of tip end thickness of ZrO〓 tube and amount of reference electrode on response time and thermal equilibrium in oxygen probe were investigated. The optimum tip end thickness of ZrO〓 tube and amount of reference electrode addition were determined. It is found that the heat transfer in oxygen galvanic cell is the rate limiting-step in the response process. The national oxygen probe WOS Ⅱ type was designed and manufactured. By three batches of industrial tests its specification reached the level of American Celox Ⅱ type oxygen probe.

在第三章中分别从参比电极、高温绝缘水泥、插接件等组元入手，着重分析了其性能和结构，开发出了适合于钢液定氧用的Cr-Cr〓O〓参比电极，解决了Cr-Cr〓O〓参比电极高温产生收缩问题，解释了电动势曲线产生峰值的原因；开发了适合于定氧测头使用的水玻璃基耐火水泥，其高温绝缘电阻在1600℃，10秒以内为10MΩ左右；同时对ZrO〓管头部厚度、参比电极量对响应时间的影响以及定氧测头中的热平衡进行了研究，得出了合适的ZrO〓管头部厚度和参比电极加入量，确定了氧浓差电池中的传热是响应过程的限速步骤；设计制造了国产WOSⅡ型定氧测头，进行了三次现场定氧测试，其技术指标达到了美国Celox型定氧测头的水平。

There is another way to help your friends or other nearby people to find you.Give them a signal by shouting or whisting three times,stop then shout or whistle three times.

还有另一种帮助你的朋友或附近的其他人找到你的方法：通过大声呼喊或吹3次口哨，停止后大叫或吹口哨三次。

E : Very often we have two or three typhoons during the summer .

While insomnia is little understood by medical science, it is fairly common among pregnant women, especially in the second and third trimesters when the growth of the belly can cause discomfort in the back.

而失眠是不大理解的医学科学，这是相当常见的孕妇当中，尤其是在第二次和第三次时，晚期的增长，腹部不适，可能会导致在后面。

According to the objective of third-order derivative related to torsions, the formula to calculate the cubic optimized Hermite interpolation curves is given. And then we propose a new method to construct curves.

如果以与挠率有关的三阶导数为目标，给出优化三次Hermite曲线的计算公式，从而提出一种新的曲线构造方法。

However, because this is the first of three this year, the cycle of dramatic growth this symbolises is just beginning.

然而，由于这是今年三次变化中的第一次，这样戏剧性的循环象征着显着的增长才刚刚开始。

He is tapped to conduct the first three of the five planned spacewalks.
