同时共存的

Moreover,the existence and global stability of the periodic solution of the system are also discussed when both populations coexist.

但是，两种群不可能同时绝灭，并且在两种群共存的情况下，讨论了周期解的存在性与全局渐近稳定性。

C values plotted against δ 15 N indicated significant partitioning in two-dimensional space among the three carnivores.It was reasonable to propose a food resource partitioning among alpine weasel,steppe polecat and upland buzzard,which partially revealed their co-existence mechanisms.

3种食肉类的稳定性碳和氮同位素分布模式在二维空间上存在明显分割，由此说明，香鼬、艾虎和大之间存在明显的食物资源分割现象，同时也反映了三者在高寒草甸生态系统内共存的基础。

And responses under the principal parametric resonance,superharmonic reso-nance and subharmonic resonance are discussed respectively.

文中分析了几类典型方程在退化情况下的局部稳定性，同时研究了一类较广泛的周期参数激励与外激励共存的系统在各种不同情况下的共振响应及其分叉行为，并用奇异性理论进行了分析，绘出了系统的分叉响应曲线。

Our results indicate that the plant can only abscise fruits oviposited by parasitic wasps before pollinating wasps in fig-fig wasp mutualism, but do not abscise the fruits parasitized by wasps ovipositing simultaneous or later than pollinating wasps, implying that abscission can not sufficiently maintain the fig-fig wasp mutualism.

结果表明：脱落机制并不能完全阻止非传粉小蜂的寄生，榕树只能选择性地脱落掉先于传粉小蜂产卵的榕果。这也同时表明维持榕树与榕小蜂互利共存的机制不仅仅只有榕果的脱落机制，可能还存在其它未被发现的机制。

Objective. To show retrospective analysis of 21 consecutive patients who underwent simultaneous surgical treatment for progressive spinal deformity and coexisting intraspinal pathologies (tethered cord and/or diastematomyelia).

目的：回顾分析21个病人，这些病人因为进展性的脊柱畸形和共存的椎管内病变（范围束缚和/或脊髓纵裂）同时接受外科治疗。

The new opinion and mechanism that the simultaneously adsorption of complex pollution of both organic and heavy metals will be achieved on soil modified with amphoteric surface modifying agent, which have both charged group and organophilic group on one ASMA molecule, were proposed at first time, and its rationality was testified at the same time; The 50% was the critical CTMAB modifying ratio of soil CEC at which the organophilic bond modifying mechanism was emerged; The thermodynamic characteristics of adsorption of OPT and HMP on OMS were discovered ; The study revealed the surface peculiarity of OMS that the modifying agent were distributed at uneven scatter mode and multi-characters surface were coexisted on surface of OMS, revealed the adsorption peculiarity of OMS that multi-mechanisms were coexisted, confirmed the unequal charge amount modifying mode of OMS in which dual-modifying mechanism of both ion exchange and OPB were processed at the same time, and confirmed that the adsorption hobby to CTMAB was higher than that to Ca2+ on Lou soil.

首次提出了用两性表面修饰剂对土壤进行修饰改性，利用两性表面修饰剂所具有的荷电基团和疏水基团达到对土壤中有机、重金属污染物同时吸附的思路和机理，并通过实验证实了所提设想的合理性；发现了土壤CEC值的50%修饰比例是CTMAB开始显现以疏水键机制对土土样表面进行修饰的临界点；揭示了有机修饰改性土对有机物、重金属吸附过程的热力学特征，填补了该项研究工作的空白；阐明了修饰剂在改性土表面呈分散态的非均匀分布，改性土表面具有不同性质表面共存的表面特征和对污染物多机制共存的吸附特征，确定了阳离子表面修饰剂在土表面的修饰是一种离子交换和疏水键结合两种机制相伴并行且为非等电荷量交换的修饰反应模式，以及土具有对CTMAB的吸附偏好性远大于对钙离子吸附偏好性的特征。

During a period of intervening time;meanwhile.

伴随的同时发生或共存的；相伴的。

So, It is undoubted for the existence of nomadic settlements. From 2005-2007, combining the extensive archaeology investigation with the purposive archaeology excavation of Dongheigou site, it was raveled that this site includes rock paintings, stone high flat, graves and stone settlements which constitute "nomads triad". According to integrated research, it was concluded that the site includes both extraneous and aboriginal culture elements, reflecting the relationship between conqueror and loser, which is accordant with that Xiongnu defeated Rouzhi in the same region and period.

新疆巴里坤东黑沟遗址就是在东天山北麓发现的一处大型古代游牧文化的聚落遗址，2005~2007年进行了全面调查和重点发掘，揭示了以墓主为代表的外来文化和以人牲为代表的土著文化同时共存的现象，反映了征服者与被征服者的关系，与文献所载的匈奴于西汉初年在东天山地区击败月氏的历史相合。

The state of higher financial risks and frequent economic and social volatility must be redressed.

国际社会有必要改革国际经济规则，加强对全球化进程的引导和管理，在追求效率的同时兼顾公正，降低风险，引导全球化朝着有利于各国共赢、共存的方向前进。

Thirdly, by con-utilaziont of many methods such as exploitation and geology, dynamic producing process monitoring, water invasion behavior, core analyis and numerical simulation, 10 kinds of reservoir scale remaining oil distribution pattern in the steam huff and puff super heavy crude oil reservoir was put forward. Also, remainling oil distribution in the sand bed scale and sublayer scale were pointed out.Fourthly, Microcosmic displacement experiment was conducted for hot water driving in 100℃and 120℃. and steam drive at 170℃condition. Microcosmic remaining oil distribution characteristics were summarized. Remaining oil microcosmic distribution by steam drive at 170℃is different from that at 100℃, 120℃hot water driving. After the steam drive, there are three types of remaining oil distribute regular pattern, whic is impacted by many affecting factors like pore configuration, wettability and interfacial tension.

分析了砂层组规模和小层规模的纵向和平面剩余油分布规律。4、通过微观驱替实验，研究了100℃和120℃的热水驱及170℃蒸汽驱条件下剩余油的微观分布形态。170℃条件下剩余油微观分布形态同时受孔隙结构、润湿性及界面张力多种因素的影响，主要有三种形式：在油、汽、水三相共存的孔隙中，剩余油分布于汽、水之间，为薄膜状和弯月状；在只有油、汽两相共存的孔隙中，大孔道中主要是蒸汽，剩余油在细小的孔喉和孔隙角隅处以段塞或不规则状态存在；由于高温水蒸汽对原油具有萃取作用，剩余油以一种细小的珠滴状存在于孔隙表面。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.
