The leaf modules of different age tillers of grey green and yellow green ecotypes had the same regulation of allometry and biomass accumulation at the reproductive stage in the Songnen Plain. All quantity indices, such as biomass, length and width of leaf and regulation of biomass accumulation, were different between the two habitats of the same ecotype and between the two ecotypes at the same habitat. The results showed both ecotypes had adapted to their corresponding habitat and obviously had ecological plasticity.

在松嫩平原的繁殖期，灰绿型和黄绿型羊草不同龄级分蘖株叶构件具有相同的异速生长和生物量积累规律。2个生态型羊草叶构件的生物量、叶长、叶宽、生长和生物量积累规律等在相同生态型不同生境之间，相同生境不同生态型之间，以及不同龄级分蘖株之间的各个数量指标均有一些差异，但变化幅度不大，是2个生态型对其所在生境产生的相应适应性反应，具有明显的生态可塑性。

X-ray diffraction is one of the most common and efficient ways to measure a superlattice structure. This dissertation displays the detail results for characterization of Ge〓Si〓/Si superlattices by x-ray diffraction (including x-ray small angle diffraction and double crystal diffraction). It was found, when the growth temperature is lower, the intensities of xray small angle diffraction peaks are modulated by a periodical function, which indicates that both sets of interfaces of the superlattice is highly flat; when the growth temperature is higher, the diffraction peak intensities are simply decay with the increase of diffraction vector, which indicates that one set of interfaces is highly flat but another is not; when the growth temperature is very high, the diffraction peaks are reduced more rapidly, which indicates that both sets of interfaces are not ideal.

本文详细介绍了用X-射线衍射（包括X-射线小角衍射和双晶衍射）方法对Ge〓Si〓/Si超晶格结构特性测试的结果，尤其是发现，当Ge〓Si〓/Si超晶格的生长温度较低时，X-射线小角衍射谱峰的强度随着衍射波矢的增加而周期性调制，表明超晶格的两套界面都十分平整；当生长温度较高时，Ge〓Si〓Si超晶格的X-射线小角衍射谱峰的强度随着衍射波矢呈简单的衰减变化，对应于超晶格内有一套界面不平整的情况；当生长温度进一步提高时，X-射线小角衍射峰明显减少，表明超晶格内两套界面都不理想。

At present, China Excellent javelin thrower lower limb segment placed before the positive tread in the poor backward angle variations of the trunk is small, the level of Pull angle fluctuations, lead to physical decline in the focus of the horizontal velocity, cross-step and go beyond the combination of devices is not ideal, beyond the equipment is not sufficient.

目前我国优秀标枪运动员下肢环节的积极蹬地前摆欠佳，躯干后倾角度变化幅度小，水平拉引角波动较大，导致身体重心水平速度下降，交叉步与超越器械的结合还不理想，超越器械不充分。

Anaximander, a disciple of Thales, maintained that the first principle from which all things evolve is an intangible, invisible, infinite substance that he called apeiron ,"the boundless."

Anaximander是Thales的弟子。他的首要原则是主张所有物质都是从虚无物变化来的，这种物质无实体，不可见，不确定。

Ever in motion, blithesome an cheery, still climbing heavenward, never aweary: clad of all weathers, still seeming best, upward or downward motion thy rest; full of a nature nothing can tame, changed every moment, ever the same; ceaseless aspiring, ceaseless content, darkness or sunshine thy element; glorious fountain!

常在动中，载愉载恬，永欲摩天，不知疲倦；不分晴雨，总觉欢乐，或上或下，动中休息；精力充沛，不屈不挠，刻刻变化，不改其操；不断亢杨，不断满足，无昼无夜，一元太极；灿哉喷泉，我心榜样，新颖多变，恒走向上！

The immune system is exquisitely sensitive and can distinguish between very subtle changes in chemical composition. Patients may be tolerant of a given drug but intolerant of another drug with closely related chemical structures. There is evidence that patients tolerant of penicillin may be intolerant of cephalosporins.

免疫系统非常敏感，可以识别化学物质的细微变化，病人可以耐受一个给定的药物，而可能不能耐受化学物质非常相近的另一个物质，也有证据表面有的病人能耐受青霉素而不能耐受头孢。

Nowadays cadge kind had produced tremendous change, the person that beg helps should sit in the company only, call, lane get what rank, although 100 dawn give birth to already gone number to carry, but the control nowadays but the beg side that military accomplishment ranks got a lot of profit through this rank, hear their beg side is doing what IM recently, the old big 7 fair to be profuse in praise in a low voice, knowing is dim in, think fondly of Where is this 100 Xiao Sheng's classmates?

如今的乞讨方式已经发生了天翻地覆的变化，丐帮的人只要坐在公司里，打打电话，弄弄什么"排名"，虽然百晓生已经死去数载，但如今的把握"武功排名"的丐帮可是通过这个排名弄了好多油水，听说他们丐帮最近在弄什么IM，老大洪七公对于"小声"赞不绝口，不知道是不是冥冥之中，怀恋这位"百晓生"同学呢？

The result shows that the main factors,which affect the technical quality of the cathode assembly preparation,are surface oxidization of emissive layer,impurity pollution,doped concentration nonuniform,less variation of doped concentration gradient,the sticking stress of GaAs and glass,and the main factors,which affect the cathode activation,are the degree of vacuum for activation at lower than 8x10-8Pa,the partial pressure of H2O,CO,CO2 and C in the vacuum residial gas at higher than 10-8 Pa and the improper caesium and oxygen refining.

结果表明，影响台外工艺质量的主要因素是外延材料缺陷多、发射层表面氧化、杂质污染、掺杂浓度不均匀、掺杂浓度陡度变化小及GaAs与玻璃粘接产生的应力大；影响台内工艺质量的主要因素为阴极激活真空度低于8×10-8Pa。真空残气H2O.CO.CO2及C分压大于10-8Pa。阴极激活铯和氧源提纯不彻底。
