There are two parts in this thesis. Part I focuses on the transient effect in InGaP/GaAs hetero-junction bipolar transistors. Part II focuses on the P memory effect and buffer-layer-quality determination using C-V measurement in AlGaAs/GaAs pseudomorphic high-electron-mobility transistors. The characterization of hydrogen passivation for InGaP HBTs grown on semi-insulating GaAs substrates is studied. The transient effect caused by hydrogen passivation results the current gain ?

本论文分两部分，第一部份讨论在磷化铟镓的异质接面双载子电晶体中，由於氢的包覆效应产生的特性之研究，由於氢在此种元件中所造成的载子包覆现象是引起电流增益增加的暂态现象的主要原因，本论文提出一个计算氢包覆比例的模型，并与SIMS量测的结果相比对，经过几次热回火处理，此种暂态效应可以被消除。

本文分四大部分，首先介绍了远程教育的相关理论；然后重点分析了远程教学中网络学习环境设计的理论基础：三大学习理论、教学模式、学生的交互方式等，以及如何在此理论指导下设计出适合学生自身特点的学习环境，并提出了新的组织框架；在第三部分中我结合以上理论分析设计了《模拟电子线路》课程学习与测试系统，分别从它的必要性、功能分析、系统设计、具体实现等几方面进行了详细的阐述；最后一部分是对全文的总结。

This picture was accompagnied with feeling sick in a strange way i never would forget, it took just a few seconds technical abilities were i suppose not enough refind for 3d, this problem ten years after did not anymore exist and 3d pictures apear in colour realistic live experiences, dreams even while awake.

这幅画卷伴随着恶心的感觉，以一种我无法忘记的奇怪的方式。短短几秒钟的技术，我猜测还不足以让我细加区分三维，这个问题10年后不再存在，并且3d画面出现在彩色的现实生活的经历中，甚至在你醒来时依然在做梦。

A very clear memorie as a small girl, seeing on a walk troughthe park in my head some 3D picture of twisted wires, hair or woolgetting thin and getting thik again, getting big and getting small.this picture was accompagnied with feeling sick in a strange way inever would forget, it took just a few seconds technical abilitieswere i suppose not enough refind for 3D, this problem ten yearsafter did not anymore exist and 3d pictures apear in colourrealistic live experiences, dreams even while awake.

作为一个小女孩的非常清楚的记忆，我看到在我的脑海里，有些扭曲的像电线、羊毛或头发的三维图像变的越来越细，又变的愈来愈粗，变的越来越大，又变的越来越小。这幅画卷伴随着恶心的感觉，以一种我无法忘记的奇怪的方式。短短几秒钟的技术，我猜测还不足以让我细加区分三维，这个问题10年后不再存在，并且3D画面出现在彩色的现实生活的经历中，甚至在你醒来时依然在做梦。

Around 11:50 am, inside the out-patient department of Affiliated Hostpital of Hubei University of Chinese Medicine located at Pang Xie Jia, Wuchang Dist When Professor Mei was diagnosing a female patient with his students, A middle-aged man suddenly showed up at the door, threw in a glass bottle filled with gasoline, fled after quickly igniting it into big fire and resultantly left many injured.

昨日中午11时50分左右，位于武昌螃蟹甲的湖北中医学院附属门诊部内，68岁的梅教授和他的几名学生正在给一名女患者看病。突然，一中年男子出现在门口，将一玻璃瓶汽油扔进来，迅速点燃后逃走，大火造成多人烧伤。

The principal best management practices for Costa Rica are: a well drained soil or a good drainage system in the field (banana yield is hurt with only a few hours of oxygen depletion in the root zone), b adequate control of nematodes, c adequate control of black sigatoka and d a good fertilizer program which includes rates of fertilizer equal or higher than 300-300-600 kg/ha/year of N- P2O5- K2O split in 12 applications during the year.

这些最好的管理措施为： a ）良好排水土壤或田间良好排水系统（根区缺氧几小时就会损害香蕉产量）， b ）有效地防治线虫， c ）有效地防治香蕉叶斑病和 d ）良好的施肥计划，施肥量等于或高于300-300-600公斤 N - P2O5- K2O /公顷/年，一年中分12次施入。

On the dock, Mr Nardi and I are met by Clayton Coffin, the farm manager, who was a wintertime resident of Sorrento before he moved inland a few months ago.

耐迪先生和我在码头上碰见了这个农场的经理科分克莱顿，之前他是索伦托的冬季居民，前几个月搬到了内陆。

The next year I did better still, for I spaded up all the land which I required, about a third of an acre, and I learned from the experience of both years, not being in the least awed by many celebrated works on husbandry, Arthur Young (10) among the rest, that if one would live simply and eat only the crop which he raised, and raise no more than he ate, and not exchange it for an insufficient quantity of more luxurious and expensive things, he would need to cultivate only a few rods of ground, and that it would be cheaper to spade up that than to use oxen to plow it, and to select a fresh spot from time to time than to manure the old, and he could do all his necessary farm work as it were with his left hand at odd hours in the summer; and thus he would not be tied to an ox, or horse, or cow, or pig, as at present.

第二年，我就干得更好了，因为我把总需要量的全部土地统统种上了，只不过一英亩的三分之一，从这两年的经验中，我发现了我没有给那些农业巨著吓倒，包括亚瑟·扬的著作在内。我发现一个人如果要简单地生活，只吃他自己收获的粮食，而且并不耕种得超过他的需要，也不无餍足地交换更奢侈、更昂贵的物品，那末他只要耕几平方杆的地就够了：用铲子比用牛耕又便宜得多；每次可更换一块新地，以免给旧地不断地施肥，而一切农场上的必要劳动，只要他夏天有空闲的时候略略做一做就够了；这样他就不会像日前的人们那样去和一头牛，或马，或母牛，或猪猡，捆绑在一起。

Having analysed the localization of several typical methods for traveltime computation(finite difference method,linear interpolation method and so on) in briefly,authors put forward a method for traveltime computation based on nonlinear interpolation ,and deduced its calculation formula.

在简要分析目前最典型的几种地震波旅行时计算方法(如有限差分法、线性插值法等)局限性的基础上，提出了一种基于非线性插值的地震波旅行时计算方法，并推导了其计算公式。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
