使同时发生

Produces new profound change, the trend of world much polarization and economic globalization continues to develop eclectically in music, competition of comprehensive national power is intense with each passing day, all sorts of contradictory daedal; on the other hand, current our country still is faced with a developed country to wait for a respect in economy, science and technology dominant pressure.

对外开放在促进国内发展的同时，也使我国经济面临的风险和不确定性增多：一方面，国际局势发生新的深刻变化，世界多极化和经济全球化的趋势继续在曲折中发展，综合国力竞争日趋激烈，各种矛盾错综复杂；另一方面，当前我国仍面临发达国家在经济、科技等方面占优势的压力。

The analysis of thermal behavior and chemical structure show that the three main reactions do not initiate simultaneously. Dehydrogenization and cyclization reactions begin at the initial stage of stabilization, while oxidation reaction takes place on the precondition of cyclization reaction. Cyclization reaction has induction period that is influenced by temperature and heating rate.

热分析和化学结构分析的结果表明，预氧化过程中的三大主要反应并非同时进行，脱氢反应和环化反应从预氧化初期开始，而氧化反应需要以环化反应为前提条件，随后进行；环化反应具有一定的诱导期；在氧化性气氛中，首先发生脱氢反应，氧对环化反应起到了阻碍作用，使整个过程顺利可控。

In our previous work,we found that CDB underwent remarkable thermal decomposition at 90～120℃,which yields dithiobenzoic acid and related derivatives,it can affect the polymerization rate, molecular weight,and molecular weight distribution of the resulting polymers.

我们组发现一种常用的链转移剂CDB在加热情况下会发生热分解，分解产生的双硫酸会对RAFT过程产生一定的阻聚影响，同时使聚合部分不可控，即产物分子量不可控和分布变宽。

ASR1 is a gene from early auxin-responsive GH3 gene family, and the protein encoded by this gene is overexpressed in the mutant, which results in the following morphological phenotypes including dwarf, epinastic rosette leaves, and restrained lateral root formation, etc. Meanwhile, ASR1 may modify the plant defense signaling molecule salicylic acid in vivo, and therefore asr1 mutant is more susceptible to the infection from the pathogen Pseudomonas syringae.

ASR1属于生长素相关的GH3基因家族，它编码的蛋白质在突变体内过量表达，并造成植株矮化，莲座叶片向下卷曲，侧根发生受到抑制等形态表型的改变，同时，ASR1可能还参与了植物体对抗病信号分子水杨酸的调控或修饰过程，并使asr1突变体对病原菌丁香假单胞杆菌的侵染更敏感。

With the reduction toward maleness or femaleness of cucumber by treatmentswith exogenous GA3 or ethrel,the endogenous levels of ethylene,ACC,GA1-3,ABAand EFE activity all changed.

利用外源GA3和乙烯利处理黄瓜，使性别表达雄性化或雌性化的同时，其内源乙烯，ACC，GA1-3和脱落酸，以及乙烯形成酶活性均发生了变化。

Through a stretch-based mesh parameterization process, this paper finally achieves the homomorphous target mesh, which is then used to render the target image by texture mapping.

另外，该方法在参数化的过程中增加了对显著区域和背景结构的约束，能够在保持并增强图像中重要物体的同时，使适应图像的结构不发生明显形变。

Torrential rain have been pounding much of Mexico for days, triggering mudslides in the western state of Michoacan that killed at least a dozen people, causing rivers to break their banks and setting off flooding in the capital and nearby states.

几日暴雨袭击了墨西哥大部，触使Michoacan州西部发生泥石流，造成至少12人死亡，同时引起首都及州附近河流崩堤，洪水泛滥。

The mains results are as follows: 1,In Scirpus speices, the allocation to sexual reproductive ramets and vegetative ramets varied with environmental conditoin and life history stages. This makes the species adapt to tidal flat stresses and utilize heterogenetiously distributed resources.

主要结果有： 1，海三棱麃草中，随年龄增加和生境改变，植物的有性繁殖和营养繁殖构件的生长速率，以及球茎贮存物质的比例发生改变，这种特性使物种适应高胁迫下的潮滩生境，同时提高了植物体利用异质性资源的能力。

If GVHD occurred, GCV would be administered in order to kill TK〓T lymphocytes selectedly and to control GVHD, while preserving therapeutic effects of T lymphocytes.

将TK基因体外转染供者T细胞成为TK〓T细胞，然后和CD34〓细胞混合移植，一旦发生GVHD，则给予特异性药物丙氧鸟苷治疗，选择性杀死引起GVHD的TK〓T细胞，使GVHD得到控制，同时又可保留T细胞的治疗作用。

Salicylic acid may mimic temperature acclimation to some degree by also generating H2O2 and enhancing heat tolerance in mustard (Sinapis alba L.) seedlings.

水杨酸在一定程度上可仿效热锻炼，外源施用SA和热锻炼均可提高芥末幼苗耐热性，同时使体内H2O2含量发生变化。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
