The main results and conclusions are as followings.1, The histone deacetylase inhibitors were used to feed the larve of the fly, and then the polytene chromosomes were observed under the microscope.

得到的主要结果和结论如下： 1，通过用去乙酰化酶抑制剂处理果蝇幼虫，观察果蝇多线染色体在热休克基因处的形态变化，发现去乙酰化酶抑制剂介导的乙酰化水平的升高可引起染色体结构的显著变化，推测乙酰化修饰不仅影响分子间的相互作用而且还可以影响染色体的高级结构。

The reconstruction of past variations in lake level, water chemistry and limnological conditions may provide key site information on the post-glacial climate change of the region.

重建黄旗海水位、水化学和湖泊生物学变化历史可为研究我国夏季风边缘区冰后期气候变化提供重要环境记录。

Only in lower β situation (For example: the value of β at the equator of the sun's surface is 0.25 or less), can we reappear the typical shape of looplike CMEs: the legs of the looplike CMEs at the surface appear between the open and closed magnetic field, show little movement in the latitudinal direction; the initial change of the top material appears on both sides of the current sheet during its outward propagation, the relative variation of density at the top becomes less than both sides.

只有在β较小(如太阳表面赤道处β〓等于0.25)的冕旒背景下，才可重现典型类环状CMEs观测形态：足部出现在开场与闭场的交界面上，在纬向基本不动；CMEs顶部物质密度变化在传播过程中比两侧物质密度变化小。

What we can conclude from the observation and seed-checking on morphic fectures of the treating group and comparison groups current generation and third generation is:apparent changes incurred to the leaf shape and the thickness of muskmelon when being treated by certain level of energy and dosage which can be inherited.

从各处理组与对照组当代和第三代苗期形态特征观察、考种中发现：在一定能量和剂量组合下，处理组香瓜叶型和果肉厚度发生了明显的变化，这种形态学变化是可遗传的。

According to the theory of the coagulation method it can be classified two types, one is the measure with photoelectric and nephelometric analysis; the other is the measure with double coil and a magnetic steel ball. coagulation method is physical quantity changes below coagulant acting on blood plasma, for example light、electricity、machine movement etc, and then the data is analyzed by computer to final result, so coagulation method is also called biology-physics method. Photics'blood coagulation apparatus determines coagulation by nephelometric'changes in the coagulate process.

凝固法是通过检测血浆在凝血激活剂作用下的一系列物理量的变化，由计算机分析所得数据并将之换算成最终结果，所以也可将其称作生物物理法；光学式血凝仪是根据凝固过程中浊度的变化来测定凝血的；双磁路磁珠法其原理是利用血浆凝固过程中，在其内部运动的物体所受阻力增加，因此通过测定受阻情况可以反映血浆凝固情况；另外近些年还有很多人采用压电石英晶体法来进行血凝研究。

There are 339 reservoirs in especially high watercut stage with 1.52 billion tons of OOIP which accounts for 43.1 percent of the Shengli oildom. Development status and character of these oilfields has changed a lot. The paper has demonstrated the trend of development indexes.

特高含水期油田开采程度、开发状况、开发规律较前一阶段发生了变化，本文研究了常规水驱开发油藏特高含水期开发指标的变化规律，结果表明随着含水上升，液量下降，含水上升幅度减缓，产量、油井开井率及新井单井增加可采储量不断减小。

Depositional sequences in different depressions of the complex faulting lacustrine basin were mainly controlled by both the episodic tectonic movements with different orders and the periodical palaeoclimatic variations. Both of these parameters controlled fluctuation of lake level and also variations of the accommodation spaces.

复式断陷不同断陷内的层序，主要受旋回内不同级别幕式构造运动和气候周期性变化的控制，两者的共同作用影响著湖平面的升降和可容空间的变化。

Secondly, the self-adaptive models of porcelain, metal base, cement, dental root, gutta percha point, periodontal membrane, cancellous bone and cortical bone were reconstructed based on the post-core crown parameters.

将读取数据导入Pro/E软件中，先将桩核冠进行参数化（参数包括桩核冠的直径、长度、锥度、倒角等等），同时根据桩核冠的参数，分别建立可随桩核冠参数变化而自适应变化的饰瓷、金属基底、粘固剂、牙本质、牙胶尖、牙周膜、松质骨和皮质骨的实体模型。

The results showed that:1. Changes of Photosynthesis and Relative Physiological Characteristics of Photinia frasery Dress Seedlings under Different Drought in SpringAlong with the stress time extended and stress extent increased, leaf water content, photosynthetic pigment content and photosynthetic indexes of Photinia frasery Dress were inhibited in different levels, but the anthocyanin content, MDA content and membrane permeability increased distinctly.

结果表明： 1。不同程度干旱胁迫下红叶石楠叶片光合作用及相关生理特性的变化随着胁迫时间的延长和胁迫程度的加剧，红叶石楠的叶片含水量、光合色素含量以及Pn等光合基本指标都受到了更深程度的抑制，且可利用的光强范围越来越小，而花色素苷含量、MDA含量和细胞膜透性大幅增加，保护酶系统(SOD、POD、CAT)活性随着胁迫时间的延长，总体表现为先升高后降低，但在同一时期，随着胁迫程度的加剧，酶活的变化趋势有异。

Dramatic changes in land use of western China have taken place since the beginning of the 21st century due to unique physiographical characteristics,and some complicated social,economic and political factors.These factors are closely related with land resources utilization relative to agriculture,forestry,and animal husbandry as well as sustainable development relative to urbanization and land degradation.

由于其特殊的自然地理特征和社会、经济、政治等驱动因素的复杂多变，本区的土地覆盖发生了很大的变化，这些变化同农业、林业、牧业等与土地资源利用有关的产业发展以及城市化和土地退化等可持续发展问题密切相关。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
