So it is different from the case for composite laminated shell with anti-symmetrical lay-up.

这与反对称铺层复合材料层合壳的双稳态曲率方向相同的情况不同。

That tenth of a point on the logarithmic pH scale actually means a roughly 30 percent increase in acidity.

因著海洋pH值从上个世纪8.2变为8.1，被称为有孔虫的微小生物壳的厚度变薄了。pH值是对数刻度，这0.1实际上就是酸度大致增加30%。

Based on the Timoshenko-Mindlin hypothesis and the Hamilton Principle, a set of governing equations of motion for the laminated non-circular cylindrical thick shells were founded.Using the Galerkin procedure,the Mathieu equation only with time variable was obtained,and this equation was solved by the method of increase harmonic balance.

基于Timoshenko-Midlin假设及Hamilton变分原理，建立了层合中厚非圆柱壳的非线性运动控制方程，采用伽辽金技术，得到仅含时间参数的Mathieu型方程，然后应用增量谐波平衡法进行求解。

Now used loosely to mean any type of boards for case-making.

现在则笼统的指任何用来造书壳的纸板。

Until recently, it was thought that such shells around planetary nebulae were a rare phenomenon.

到目前为止，人们依然在思考行星式星云周围产生这种壳的罕见现象的原因。

With the help of the software of nonlinear finite element analysis ANSYS to perform the modeling with parametric programming, monolayer grounded ovaloid shell with buckling-restraining braces was analyzed.

利用有限元分析软件ANSYS进行参数化编程建模，对带有屈曲约束支撑的单层落地椭球网壳的减震性能进行分析。

AT POPE'S CREEK, on America's Potomac river, there's a pre-Columbian rubbish tip of oyster shells covering 30 acres, to an average depth of ten feet.

在波拖马可河上游，有一条POPE'S小溪。在哥伦布发现美洲大陆之前那里就有一处面积达30英亩，平均深10英尺的牡蛎壳的垃圾堆。

In the development of the deep manned submersible, the safety of the manned spherical pressure hull is of the most concern.

在载人潜水器的研制过程中，载人耐压球壳的安全性最受关注。

There were four newly hatched chicks, a day old - little specks of pulsating life no more than a mouthful; and he ate them ravenously, thrusting them alive into his mouth and crunching them like eggshells between his teeth.

窝里有四只刚出壳的小松鸡，才一天大——就像点点跳动着的生命之光，还不够他吃上一口；他把它们活活塞进嘴里，贪婪地大嚼大咽，像嚼蛋壳似地把它们在齿间碾碎。

Book sealed output of the shell to be consistent with the order, also taking into account the number of distribution page.

书封壳的生产量要与订单相一致，另外还要考虑配页后的数量。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
