The result shows that: The variation rhythm of the sensitivity index changed unanimously for Jensen,Blank and Stewart water production functions of spring wheat in Liangzhou city,the volume is small in the former stage,then become large at the middle stage,and less at the last stage. Jensen and Stewart water production functions are better of spring wheat in Gulang County in 1987-1989. The Variation rhythm of water deficiency sensitive index is unanimous: the volume are small at first,then large at middle,and diminish at last. The Variation rhythm of water deficiency sensitive index is unanimous in Jensen,Blank and Minhas of flax in Liangzhou county in 1987-1989. The water deficiency sensitive index in Gulang district in 1987-1989 models bad,are too many minus.

For, now, the last of the fleet of ships was round the last low point we had headed; and the last green barge, straw-laden, with a brown sail, had followed; and some ballast-lighters, shaped like a child's first rude imitation of a boat, lay low in the mud; and a little squat shoal-lighthouse on open piles, stood crippled in the mud on stilts and crutches; and slimy stakes stuck out of the mud, and slimy stones stuck out of the mud, and red landmarks and tidemarks stuck out of the mud, and an old landing –stage and an old roofless building slipped into the the mud, and all about us was stagnation and mud.

现在，那些急飞的舰队中的最后一支正绕过我们来时已经过的的低水湾，很快便不见了踪影；最后一艘满载稻草的绿色游艇、扬着棕褐色的风帆尾随其后，也很快消失了；只见几只装运沙石的驳船，形状粗糙得如同小孩们第一次学做的船舶模型，一艘艘低陷在泥浆里；一座支在桩上略显矮小的灯塔，像是踩着高跷、拄着拐杖的瘸子踏在泥浆里；泥滑的木桩立在泥浆里，泥滑的石头躺在泥浆里，红色的地标和潮标露出在泥浆里，一个破旧的码头和一座没有了屋顶的房子滑倒在泥浆里。

This project was established based on the first cooperative development of optical in situ real time detecting technique probing the atomic scale layer-by-layer epitaxy growth of oxide film. Over the last three years, we have given full play to the advantages and characteristics of both sides and have finished the assumptions and plans of this subject satisfactorily. 1. In Institute of Physics, we set up advanced oblique-incidence reflectivity difference equipment and wrote one data acquisition procedure that made the simultaneous detection of optical signal and RHEED signal into reality. 2. The first observation of sustained oscillations over hundreds of monolayers in both real and imaginary signals during the epitaxy growth of SrNb0.1Ti0.9O3 on SrTiO3 substrate in LMBE testifies that oblique-incidence is an excellent method to detect and monitor film epitaxy growth real time. 3. For the first time, we verify that oblique-incidence reflectivity difference method can be used to monitor the layer-by-layer growth mode during continuous growth through the correspondence between optical signals to atomic or molecular step edge density on the growth surface. 4. Phenomenological analysis shows that optical signals comprise three parts, the first is proportional to the average thickness of the film and depends on the bulk phase dielectric response; the second is proportional to the coverage of terraces and depends on the dielectric response of atoms or unit cells in the terrace; the third is proportional to the coverage of step edges and depends on the effective dielectric response of atoms or unit cells at step edges. This makes oblique-incident reflectivity difference technique a quantitative macroscopic method to monitor film growth.

中文摘要：本课题是在合作首次发展了氧化物薄膜原子尺度层状外延生长光学原位实时探测方法的基础上立项的，三年来，我们充分发挥双方的优势和特点，圆满完成了课题的设想和计划。1、在物理所建立了一套先进的光反射差法装置，编写了计算机系统的数据采集程序，实现了两路光学信号和RHEED数据的同步采集和显示。2、用激光分子束外延在SrTiO3基底上生长SrNb0.1Ti0.9O3薄膜，首次观测到连续外延几百个原胞层，周期振荡的光反射差实部和虚部信号，证明了光反射差法是一种能原位实时探测与监控薄膜层状外延生长的好方法。3、首次验证了通过对生长表面原子或分子台阶密度的响应，光反射差法可用于原位实时监测在连续生长条件下薄膜的层式生长模式。4、通过唯象理论的研究，证明光反射差信号由三项组成，第一项只与薄膜的平均厚度和宏观光学电介质常数有关；第二项与分子台阶面覆盖度和台阶面上分子层的光学电介质常数有关；第三项与台阶边缘的覆盖度成正比，并和在台阶边缘的分子的有效光学介电常数有关。

I still remember a cold evening in 2003's winter,when the snowflake was blusterous in the sky,and when the road was much pale owning to the ice on the ground, and I had only two choices in front of me,going abroad or pursuing a postgraduate degree,maybe others didn't know my suffering,but I did,for my English was so poor that whichever I chose ,it would not be avail for me at last,I participated in a series of English classes,reading and writing all day long,I was very sorry that I had troubled too many friends, as a result ,I could simply communite with our foreign professor,but the problem was not simple,I got a low mark in my Toefl test,thanked to the language class in the school abroad,I arrived at Quebec three monthes later,my first impression about this city was cold, since my hometown is located in the south of the Yangtze River, I have to imagine what does the 'heavy snow' mean cause there are always snowing lightly,to my surprise,almost half a year it was heavy snowing in the city,and it did really satisfy my desire about the snow,furthermore,we also had a long holiday,when I got there,most of my classmates were prepared for their vacation ,so I could asked for help from the senior, maybe I was not tall but sometimes the snow on the ground was taller than me,actually ,I had a good time when I stayed with my friends for we have a common language named chinese,the language class was simple for me,but the teacher was serious,whether you passed the course or not was depended on her, so you'd better don't offend her,thank godness, I passed this class at first time after a few monthes,then began with the other courses,it was said that chinese students abroad was the most assiduous in the world,and that was ture,usually,we didn't have a strong suit in the ability of a foreign language,since it asked for some understanding in our course,so I had to borrowed the note from others when I first went to class,how times fly,my GPA first was above 4.0 at that time,I phoned my relations,telling them I was okey there,but in the first evening of that holiday,a fire broke out in our dorm,I couldn't find my passport after the incident,though most of our res were moved outside,maybe it was burnt out or was lost at somewhere,but it told me that I couldn't stay longer in this city,we comforted each other for a while,''Goodbye!

雪花在2003年一个寒冷的夜空中无情的肆虐着，回家的大道被雪映的煞白，而摆在我面前的却只有两条窄窄的小路，考研，出国，也许别人不会知道我的痛苦，可是我清楚，其实我的英语很烂，现在不管选那个，好像对我都不利，我疯狂的去参加一Qy系列的英语辅导班，从早到晚大声的阅读，没天没地的做题目，以致招来了很多非议，感觉可以和外教简单交流了，可是我的托福成绩还是不堪入目，不过好在那边学校开了语言课，所以三个月后，我还是顺利来到了加拿大的魁北克省，那里给我的第一感觉就是一个字'冷'，我们江南一般下小雪，大雪是什么只能靠想像了，不过那边将近有大半年的时间都在下大雪，让我这个雪盲好好过了一把雪瘾，不过假期也长，我去的时候大多已不上课了，所以可以找到学姐，学兄，也许是我的个子不太高，不过积雪有时完全可以把我湮没，和他们在一起感觉很亲切，很开心，也许我们在一起都说汉语吧，语言课是比较简单的，不过老师很变态，她说行才行，不行你就是行也不行，所以这个老师是绝对不能得罪的，学了很长一段时间，语言考试通过了，就可以正常上课了，呵呵，都说中国留学生最刻苦了，不苦行么，我们语言能力一般都不是强项，加上课程需要一些理解的能力，初次去听课，不借阅他人的笔记是绝对不行的，时间总是晃的很快，那次的GPA成绩第一次超过了4.0，打了电话回家，报了平安，可是假期的第一个晚上就发生了一些小小的意外，一把无名火把我们住的地方烧了，当时东西都搬出来了，好在没有损失什么，可是后来检查了一下，我的护照怎么都找不到了，也许是烧了吧，也是是掉了，反正这件事也告诉了我，魁北克我是待不长了，朋友们在一起相互惋惜了一阵。

I was so dead asleep at first, being fatigu'd with Rowing, or Paddling, as it is call'd, the first Part of the Day, and with walking the latter Part, that I did not wake thoroughly, but dozing between sleeping and waking, thought I dream'd that some Body spoke to me: But as the Voice continu'd to repeat Robin Crusoe, Robin Crusoe, at last I began to wake more perfectly, and was at first dreadfully frighted, and started up in the utmost Consternation: But no sooner were my Eyes open, but I saw my Poll sitting on the Top of the Hedge; and immediately knew that it was he that spoke to me; for just in such bemoaning Language I had used to talk to him, and teach him; and he had learn'd it so perfectly, that he would sit upon my Finger, and lay his Bill close to my Face, and cry, Poor Robin Crusoe, Where are you?

开始我睡得很熟，因为上半天一直在划船，下半天又走了不少路，所以困乏极了。突然，我被惊醒，但人一下子还未完全清醒过来，只是处于半睡半醒之中，因此我以为在睡梦中有人在同我说话。但那声音不断地叫着&鲁宾·克罗索！鲁宾·克罗索！&终于使我完全清醒过来。这一醒，把我吓得心胆俱裂，一骨碌从地上爬起。我睁眼一看，原来是我的那只鹦鹉停在篱笆上面。啊，原来是它在和我说话呢！这些令人伤心的话，正是我教它说的，也是我常和它说的话。它已把这些话学得维妙维肖了，经常停在我的手指头上，把它的嘴靠近我的脸，叫着可怜的鲁宾·克罗索，你在哪儿？

First, the stations'timing process and the slot aligning are discussed. Second, the dissertation propose a resource request random access method based on feedback. The performances of this method are analyzed. Third, proceed from the considerations of the MAC protocol for the HFC system, a QOS-oriental scheduling algorithm for the MAC protocol based on dynamic TDMA is proposed. Simulation results show that the performance of this algorithm is better than that of the first come first service. Forth, two contention resolution algorithms ----p-persistent CRA and tree CRA, which are usually adopted in the HFC system, are summarized. The delay and characteristic are compared. At last, the dissertation introduces the function implementation of the MAC layer based on COM21 UPSTREAMS.

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
