不值

Nearby, where Novartis was giving away soapstone bowls carved in Kenya, a sign noted that Minnesotans, members of a Medicare committee, and state and federal employees "may be subjected to restrictions on acceptance of food, beverages or items."

是的，一杯冰冻的酸奶酪值不了51美元。但是，如果礼来的销售代表想要和他们正在联系的医生保持礼品交往，这是一个很简单的方法，而不需要对所有在会议上来访的医生进行记录，Sousa建议。

No, the PH is not the main factor; the true is that the Sodium bicarbonate only kills the fungus.

不，不是的pH值的主要因素；的事实是，碳酸氢钠只杀死真菌。

To apply ARIMA models the time series needs to be stationary. A stationary time series is one whose statistical properties such as mean, variance and autocorrelation are constant over time. If the initial time series is not stationary it may be that some function of the time series, e.g. taking the differences between successive values, is stationary.

运用ARIMA模型时时间序列必须是固定的，一组固定的时间序列是它的统计特性诸如平均值＼差异和自相关等随着时间的推移而始终不变，如果最初的时间序列不固定这是由它的某些函数引起的，以序列值之间的差额为例，它们是固定的

By perceiving the facts that average damages do not change the loading paths of a structure and that local damages will not increase component stiffness, the author presents the damage identification algorithms termed as Iterative Matrix Optimal updating and Constrained Submatrix Factor Adjustment .

根据一般损伤不引起荷载路径改变、局部损伤不会导致单元刚度增加等损伤问题的特点，提出损伤识别的"矩阵迭代优化修正法"和"带约束的子矩阵系数修正法"；并将子矩阵系数修正法推广为联合运用动力与静力测量值的损伤识别算法。

This paper attempts to find a lower-order state space symmetric model whose model reduction cost differs from the optimal model reduction cost by a prescribed precision.

该文试图寻找一个低阶隐定连续线对称性时不变系统，其与给定的高阶隐定连续线对称性时不变系统的L2 -范数误差可与最优误差值充分接近。

Since then,by applying the Leray-Schauder continuation theorem,nonlinear alternative of Leary-Schauder,coincidence degree theory,and Krasnoselskii's fixed point theorem,many researchers have studied more general nonl...

研究了一类二阶非线性常微分方程的三点边值问题多重正解的存在性问题，在非线性项不满足超线性或次线性的条件下，利用不动点指数定理得到了至少存在两个正解的几个充分条件。

The value of reference solution is measured by gravimetric titrimetry in this paper. The process of evaluating uncertainty is established according to JJF1059-1999 Evaluation and Expression of Uncertainty in Measurement.

本文应用质量滴定法为硝酸银标准溶液定值，按照国家颁布的国家计量技术规范《测量不确定度评定与表示》JJF1059——1999的规定建立了硝酸银标准溶液不确定度的评定步骤。

The tractarian state of electron is discontiguous, so the finding result of four quantum numbers is discontiguous, the logical combination of four quantum numbers are corresponding to the suitable energy state of electron.

既然电子的运动状态是不连续的，因此四个量子数的取值也是不连续的，四个量子数的合理的组合对应着电子的一种能量状态：。我翻译如下，请高手指正，急用，请高手快点。

Under the circumstances that the demand is uncertain, furthermore, the demand sometimes cannot be satisfied by production, the paper studies the production and maintenance control problem of failure prone production systems. A so-called complex trinal hedging point control policy is presented, which considers the problem purchasing extra production capacity.

摘要针对不可靠生产环境，在需求不确定并且有可能存在需求大于生产的一般性情况下，探讨了系统生产与维修的控制问题，提出了一种考虑追加生产能力的具有较强即时动态特性的复合三阈值控制策略。

The analysis shows that vertical growth is achieved thanks to discrete contact points and regions with continuous contact, that the contact pressure creates tension in the stem as observed experimentally, and that there is a maximal radius of the pole around which a twiner can climb.

这个模型可以解释为什么藤蔓不能在半径大于一定值的树干上生长，他们计算出当树干半径大于3.3倍的藤蔓自然曲率半径时，藤的尖端便不能继续缠绕树干向上生长，而是自身卷曲起来。文章的后一页半研究了摩擦力的影响，很明显，摩擦力是使藤蔓植物能够支撑自身重量的主要原因。

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％。
