When you consider what he wrote -- thirteen operas and music dramas, eleven of them still holding the stage, eight of them unquestionably worth ranking among the world's great musico-dramatic masterpieces -- when you listen to what he wrote, the debts and heartaches that people had to endure from him don't seem much of a price.

当你掂量他的作品时——十三部歌剧和音乐剧，其中十一部仍然长演不衰，八部当之无愧地位于世界音乐剧伟大名作之列——当你聆听他的作品时，他欠债不还也好，伤透人心也罢，这些代价似乎都不算什么。

When you consider what he wrote ?thirteen operas and music dramas, eleven of them still holding the stage, eight of them unquestionably worth ranking among the world's great musico-dramatic masterpieces ?

当你掂量他的作品时——十三部歌剧和音乐剧，其中十一部仍然长演不衰，八部当之无愧地位于世界音乐剧伟大名作之列——当你聆听他的作品时，他欠债不还也好，伤透人心也罢，这些代价似乎都不算什么。

The paradigmatic sort of ontological entailment is necessitation: P necessitates Q when the material conditional PQ is metaphysically necessary, or when it is metaphysically impossible for P to hold without Q holding.

存有上推导的典型类型是'必要性'：当实质蕴涵PQ是形上学必要条件时，或当"持有P但不持有Q是形上学上不可能"时，P使得Q成为必要物。

Are also given by constructing Lyapunov function. Finally, by applying the energy methods, Sobolev embedding theorems and bootstrap arguments, the global existence of nonnegative classical solutions to equations with homogeneous Neumann boundary value condition is proved when the space dimension is at most 5. Under certain conditions for the coefficients of the reaction functions, the convergence of the solutions is established for the system with large diffusion coefficients by constructing Lyapunov function.

的正平衡点全局渐近稳定的充分条件；最后，当空间维数不超过5时，应用能量估计、Sobolev嵌入定理和bootstrap技巧证明在齐次Neumann边值条件下非负古典解的整体存在性，并通过构造Lyapunov函数给出当反应函数的系数满足一定条件、扩散系数较大时该模型解的收敛性。

Nanomaterials have many new characterizes which different from the normal materials for their small size, big surface area ratio and quanta dimension domino effect, for examples, the metal with good conductor will be turned into nonmetal when the size is reduced tonanometer levels; the resistance of originally nonconductor will be descended greatly when its size is reduced several nanometers or so, and loss the nonconductor property; the general solid is steady under certain conditions, while under nanometer conditions, the capabilities will be effected greatly by the granule sizes, the newness characteristics made nanomaterials have great appliance foreground on catalyze, optics, and industry produce and so on, therefore the nanomaterials have been the hotspot for materials science, chemistry science and so on.

纳米材料由于尺寸小、比表面积大和量子尺寸效应使它具有不同于常规固体材料的新的特征，如原来是良导体的金属，当尺寸减小到纳米量级时就变成非金属型；原来是绝缘体的物质，当尺寸减小到几纳米或几十纳米时电阻大大下降，失去了绝缘体特性；常规固体在一定条件下物理性能是稳定的，在纳米状态下，颗粒尺寸对性能产生强烈的影响等等，这些新奇的特点使得纳米材料在催化、光学、工业生产等各个方面都有着广阔的应用前景，因此，纳米材料目前已经成为材料科学、物理学及化学等学科的前沿热点。1990年7月在美国巴尔基摩召开了国际第一届纳米科学技术会议，正式把纳米材料科学作为材料科学的一个新的分支公布于世。

The frequency of this synthesizer can be changed from 405700.0000Hz to 405799.9999Hz with a minimum step frequency of 1 ×10-4Hz. The measured results show that nonharmonic interrelated spurious output of the synthesizer is less than -85dB.

该综合器的非谐波相关的寄生输出小于-85dB，频率的短期稳定度是2.07×10~(-11)/0.1s、2.48×10~(-12)/1s、2.88×10~(-13)/10s；当温度由20℃变至40℃时，综合器相位漂移Δφ=28.8°；当电源电压为+16V～+19V或+5V～+6V时，综合器输出相位不变。

Nevertheless, when it comes to relative clauses introduced by inanimate antecedents, the differences between subject and object relative clauses diminish to some extent, and object relative clauses turn out to be even more frequent than subject relative clauses when the relative clause internal noun phrases are animate simultaneously.

从整体看，可及性的作用明显，主语关系从句比宾语关系从句使用更频繁，正确率更高；可当先行语为无生命名词时，主、宾语关系从句的使用差异会大幅度减小；而当从句内名词同时为有生命时，宾语关系从句的使用则会超过主语关系从句。

The computational complexity of the algorithm is polynomial growing with the sample size and the solution is the maximal margin one in the high dimensional space.

其主要的内容是：当问题是线性可分时，给出一个求解最大间隔解的方法以及当问题不是线性可分时，提出利用一核函数将样本集映

When someone says The two boards are of equal length, we assume that the equality is reckoned to some order of approximation determined by the context; if we did not, we would be required always to use nearly equal when speaking of the dimensions of physical objects.

当有人说两块木板同样长时，我们会认为由于上下文的关系，相等可以被看作大约近似；如果我们不这样想，那么当我们谈到物体的尺寸时，就要经常使用nearly equal 。

However, the orthogonal properties of wave functions can not be used to simplify the boundary conditions when the spring coefficient in the interface spring model is inhomogeneous along the circumference.

在弹簧界面模型中，当弹簧系数沿周向分布均匀时，可利用波函数的正交性简化边界条件；当弹簧系数沿周向分布不均匀时，不能利用波函数的正交性简化边界条件。

And discuss some key point of integrated management system design, include hazard identification and risk assessment and risk control in the occupational health and safety management, the measure of satisfaction target of customer, the flawlessness of law system, the integration of the integrated management system and enterprise standardization system, unify lead institution and work orgnization, integreted internal audit and integrated management review.

同时，论述了一体化管理体系构建中的几个主要问题，包括职业健康安全管理中的危险源辨识、风险评价和风险控制、顾客满意度的科学监测、法律、法规体系的完善、一体化管理体系与企业标准化体系的有机结合、统一的领导机构和工作机构、一体化的内部审核和管理评审。
