The donor impurity and grain boundary combustion-supporting agent containing acceptor impurity were added successively in the ceramic powder during ceramic powder preparation, both of them can also promote grain growing and semiconductive, and the combustion-supporting agent can be good to form insulation layer in oxidizing process.

采用一次性烧成技术研制了晶界层半导体陶瓷电容器，在瓷料配制过程中先后加入施主杂质和含有受主杂质的晶界助烧剂，两者在还原烧成时促使晶粒生长并半导化，助烧剂在氧化时有利于晶界绝缘层形成。

When in use , the lower end of the accommodation ladder shall rest firmly against the ship'sside within the parallel body length of the ship and, as far as is practicable, within the mid-ship half length and clear of all discharges

在使用时，舷梯的下端应牢固地靠在船舶平行船中体长度范围内的舷边；在可行时，应牢固地靠在船中半长范围内的船舷上；应避开所有排放口；或an accommodation ladder in conjunction with the

The effect of different calcium chloride concentration, reaction time and neutralized acid on yield of tagatose was investigated by single factor tests. Results showed that the condition, such as calcium chloride (0.01～0.03 mol/L), reaction time(20～40 min), acetum, carbon dioxide, phosphate acid to synthesize tagatose was suitable.

通过单因素实验，确定了以D-半乳糖为原料进行化学法合成D-塔格糖的工艺条件为：CaCl2的添加量在0.01～0.03 mol/L，反应时间在20～40 min，并用醋酸、CO2、磷酸中和时D-塔格糖产率较高。

Based on the analytical theory of aeolotropy,thermal distortion and temperature field distributions of Nd∶YVO4 crystal with rectangular section were investigated when the third thermal boundary condition was considerated.

以各向异性半解析热分析理论为基础，研究矩形横截面Nd∶YVO4激光晶体在有第三类热边界条件工作时，激光晶体温度场分布和晶体抽运面热形变分布。

No sooner said than done. He quickly took a sharpened axe to shape the wood; but when he was on the point of striking it he stopped with his arm in the air, because he heard a tiny, thin little voice say,"Do not strike so hard!"

说干就干。他拿起一个锋利的斧子开始砍木头；但是当他快要砍上它时他的胳膊停在了半空中，因为他听见有声音，那个细小的声音说，"不要太用力！"

The dynamic characteristics of the half-tracked air-cushion vehicle are different from other conventional vehicles. Its mechanical equation includes several parameters being related to propulsion system, air-cushion system and soil condition. This system is a higher order nonlinear time-variant system with a delay.

由于半履带式气垫车的力学特性不同于以往的常规车辆，其动力学模型包含与驱动系统、垫升系统、地面条件等有关的多个参数，属于大滞后的高阶非线性时变系统。

In most situations where music is performed in our culture it is not difficult to distinguish the audience from the performers, but such is often not the case in africa. alban ayipaga, a kasena semiprofessional musician from northern ghana, says that when his fluteand drum ensembleis performing."anybody can take part".

（47）在大多数情况下，如果是在我们自己的文化中演奏音乐，就很容易区分观众与演奏者，但在非洲，情况通常并非如此。alban ayipage，一名来自加纳北部的喀萨纳半职业音乐家在他的长笛与鼓歌舞团表演时说道，"任何人都可以参加"。

Unlike the canonical extension,the number of algebraic completion of a poset may be more.

一个偏序集的代数完备可能有多个，可是，当偏序集是并半格时，代数完备在序同构意义下却是唯一的。

He was standing between the two women, and, I regret to say, in his endeavour to act as peacemaker, he made use of rather strong language in the presence of his mother; and I was just in time to hear him say:"And all this fuss about the loss of a few pages from a rotten diary that wouldn't fetch three-halfpence a pound!"

他正站在两个女人中间，我很遗憾地说，他在努力充当和事佬时，当着他妈妈的面，用了一些相当刺耳的言辞，我进来时刚好听到他说：&就因为少了几页一磅都换不来三个半便士的烂日记就这样大吵大闹！&

Firstly, the SPN model for a single-layered LEO satellite network under half duplex mode is constructed. Then, average time delay is chosen as a key performance index to evaluate the network performance of the constructed SPN model with SPNP 6.0 software. Furthermore, the effects of arrival rate, network load, message number on average time delay are also analyzed.

首先建立了半双工通信模式下LEO单层卫星网络的SPN模型，并选取平均时延作为网络性能评价指标、采用SPNP6.0软件对该SPN模型进行了性能评价，分析了数据包到达速率、网络负载以及消息数等参数对网络平均时延的变化关系。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
