不存在的

Physical evidence cannot be wrong, it cannot perjure itself, it cannot be wholly absent.

实物证据不能是错误的，它不能作伪证本身，就不能完全不存在。

The latest cheating affairs in the University of Virginia is the case in point. This university, which is famous for his "grade honor" system, had suffered from a plagiary, for more than 60 students' papers were nearly identical to be found in the Internet. The scandal had raised huge debates in the University whether it was needed to induce supervisal when students are in test.

然后，你举的例子都是个人的一些行为，那么根据题目你应该论述这些行为是个人能够控制的还是外力决定的，如果是个人控制的，那么就说明个人对于行为有责任，存在个人责任，而不是fiction；如果是外力决定的，那么就说明个人对于行为没有责任，就不存在个人责任，个人责任只是fiction。

At the same time, it wholly summarizes existed issue in the development of Internet banks, especially in networks safety and networks risks. At the end, with analyzing networks safety and risks, this paper suggests taking effective precautious measures and developing Internet banks.

本文着重介绍了网络银行的竞争优势和网络银行发展中存在的法规不完善、电子支付业务运作程序不规范、日益猖撅的网络金融犯罪以及针对普遍存在的各种网络风险的技术防范措施(SET、SSL、CA、防火墙技术、加密技术等)。

In the first part, we discuss the properties of solutions of (0.1) system with dif-ferent diffusion coefficient and the second boundary condition. The stability of non-negative constant solutions is given, some prior-estimate of the positive steaystateare proved by using the maximum principle and lower-upper solutions, the non-existence of non-constant positive solution, the global exitence of non-constant pos-itive solution and bifurcation solution of non-constant positive steady-states areobtained.

第一章讨论了系统(0.1)在扩散系数不相同的情况下非负常数解的稳定性，运用极值原理，上下解方法确定了系统(0.1)正平衡态解的一些先验估计，然后讨论了非常数解的不存在性，非常数正平衡态解的全局存在性及非常数正平衡态的分歧解。

It is also shown that under the same conditions, the values of the LWI gain with incoherent pumping are evidently larger than those without incoherent pumping exceptΦ=0 and the time reaching the steady state is shorter; varying the initial condition doesn't change the stationary value of the LWI gain but can remarkably affect the transient evolution process of the LWI gain.

研究还表明，与不存在非相干泵浦时相比，除了相对位相Φ=0的情况外当存在非相干泵浦时系统可得到大得多的稳态增益，而达到稳态所需的演化时间也短得多；初始条件的变化不改变稳态增益的大小但对瞬态演化过程有明显的影响。

The theoretical analysis are verified by numerical simulations.Chapter 3 mainly considers a class of predator-prey model with sublinear functional response function. We deduce some sufficient conditions ensuring stability of equilibrium, nonexistence , existence as well as uniqueness of the limit cycle around the positive equilibrium.

第3章研究了一类食饵为线性密度制约，功能反应函数为次线性函数的食饵-捕食者模型，完整地对模型的平衡点的全局稳定性和极限环的存在惟一性进行了定性分析，得到了该系统不存在闭轨线，正平衡点全局稳定和存在惟一稳定的极限环的充分条件。

There are some shortcomings in titrimetry experiment in current analytical chemistry teaching materials.

目前的分析化学实验教材中关于滴定分析的实验指导还存在着一些不足，特别是对有些关键技术的指导存在着说的不清、说的不到位的情况，有必要对相关教材在修定时进行必要的补充与完善。

In addition, the general trend of underpricing is in line with the trend of stock market.

对这些结果进行进一步分析，本文得出可转债的价值低估程度与债券的票面利率之间不存在明显的线性关系，与债券距离到期日的时间即剩余期限之间存在显著的正相关，而与债券的转换溢价存在显著的负相关关系。

Unfortunately, there is inevitably difference in characteristics of the induction motors and converters in a parallel AC drive system, therefore each induction motor as well as converter can not operate at the same working point, some may be overload, some underload.

并联着的各个交流调速系统的负载是不均衡的，这是因为逆变器所带的负载—异步电动机参数及特性不可避免地存在差异，两或多台逆变器作为电源，其等效参数也很难一致，各驱动轮径总存在偏差，因此各台逆变器的输出电流和各台异步电动机的定子电流是不相一致的，有的逆变器、异步电动机可能过载，有的还可能欠载。

No significant difference indrinking capacity was found between HS and FD and its non-early satiety subgroup.Ⅱ. Pathological findings in FD fundic mucosa and its relationship with WLT.(1) significant difference was found in 5-HT positive cell counting between early satietyand non-early satiety subgroups(P.05). but no difference in mast cell counting, activity,and H.

6HS组与FD组及FD的早饱和非早饱亚组在半排时间、排出量和排出率存在显著差异(P.05)，HS组的半排时间、排出量和排出率显著低于FD组及FD早饱和非早饱亚组：HS组与FD的早饱亚组之间的阈值饮水量和饱足饮水量存在显著差异(P.05)，HS组饮水量显著高于早饱组：HS组与FD组及HS组与FD的非早饱亚组之间的阈值饮水量和饱足饮水量均不存在显著差异。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
