有前提的

The basic premise of bloodstain analysis is a droplet's size reveals how much energy was applied, its shape suggests the direction of its source and its distribution reveals how far away from a surface blood was splattered.

血液分析的基本前提是一小滴血的大小能显示出使用了多大能量，它的形状能说明它的来源方向，它的分布能显示出离血滴的地方有多远。

Under some reasonable assumptions of the'Distribution Matrix', the Riemann Problem with piecewise constant initial data is proved to have a unique Riemann Solver; furthermore, using'Wave Front Tracking Method'and properties of the'Generalized Characteristics', we prove the existence of weak entropy solution to the Riemann Problem with arbitrary initial data of bounded Total Variation.

在"分布矩阵"满足合理的假设前提下，证明了具有分片常值初始条件的黎曼问题的黎曼解算子的存在唯一性；并进一步运用"波前追踪法"和"广义特征"等得到了具有任意有界全变差初值条件的广义黎曼问题的弱熵解的存在性。

It is not a cultural nationalism in a narrow sense. The Cultural cosmopolitanism is the unique choice. All what we want is a sense of concern about our culture and a sense of self-confidence of our culture, neither self-abased nor self-important.

在这样的大背景下，健康的文化心态和开放的文化视野，是我们进行现代化建设特别是在新的世纪里建设有中国特色的社会主义文化，实现中华民族伟大复兴的必要前提。

Since the cutting force of PDC cutter is related directly and closely to its cutting angle, correct calculation and analysis on its cutting angle is the basis and premise for analyzing cutting force and bit operating load.

PDC钻头切削齿的切削载荷与齿的切削工作角度有直接而密切的关系，所以正确地分析和计算齿的切削角度，是齿的切削载荷以及钻头工作载荷分析的基础和前提。

Integrating ontologicaldifference with the difference describing in structuralism liguistics,Derridadesigned Grammatology in order to emphasize undecidability and maintain contextis the condition of decidability.

将本体论差异和结构主义语言学所倡导的差异结合起来，德里达构想出书写语言学。没有差异的同一是同语反复，差异是同一的前提。书写语言学反对绝对决定的同一，强调同一的不可决定性，主张只在具体的语境、情境之中，才有决定可言。

Based on Douglas operators, the modified wide beam propagation is presented and the number dissipate is minimized without nearly increasing the memory and computing time. The method is also more stable and accurate than ordinary WBPM. Finally, A novel wide-angle low-loss dielectric slab waveguide Y branch is presented and analyzed by modified WBPM.

接着，本论文还分析广角BPM差分格式所具有的数值色散来源，并在不增加计算时间和内存的前提下，应用Doglas算子大大地减小数值色散带来的误差，提高了计算精度，提出了改进的WBPM，而且还发现这种方法有具计算稳定的优点。

Touch screens should also avoid idioms that involve dragging; single-tap idioms are easier to control and more obvious to novice users.

触摸屏还要避免使用普通桌面系统上常见的拖放操作，对于新用户来说，在触摸屏上的单击操作还是相对比较容易和比较明显的，前提是要有明显适当的提示。

Much of the equality bill that she is shepherding through Parliament only makes sense if you believe that differences in outcomes between men and women—or white and black people, or gay and straight ones—are prima facie evidence of discrimination.

她在议会所力推的那些平等法案能够成立的前提是，人们必须相信，认为男性与女性、黑人与白人、同性恋与异性恋有什么不同的地方，都是看似公平实则不然的变相歧视。

The multiple pretreatments result in the favorable outcome, and provided the better preconditions for simple charactersrecognition method that based on template match.

最终分割出的牌照字符有较好的效果，为模板匹配等简单快速的字符识别方法提供了良好的前提。

The empirical study indicates that the convertible bonds have been underpriced significantly when considering the amending expectation.

实证分析的结果表明，在考虑修正预期的前提下，我国的转债有较大幅度的低估。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
