To avoid the permutable model of protein, the 43 Table of Triplet Codes Given by F.H.C.Crick in 1969 is in fact that one group of permutations versus the permutation elements in another group of permutations , which is a typical wrong application and a wrong calculation.

Crick 43 遗传密码表回避蛋白质分子的排列组合模型问题，根据氨基酸种类数20 和 DNA 上碱基种类数 4进行对四元素选三元素的排列组合计算建立" DNA ～蛋白质"间的一一对应，本质上是排列组合应用中一组排列组合对应另一组排列组合的具体元素。

When the sulfur concentration is in the range of 0～4 mg/L, the elemental sulfur has a linear relation with the peak current of polarography.

该方法灵敏度高，当元素硫浓度为0.1 mg/L 时仍可以看到明显峰电流；精密度和准确度较好，对1 mg/L 元素硫的测定，标准偏差为0.02；元素硫浓度在0～4 mg/L 浓度范围与极谱峰电流呈线性关系。

In this paper, we use FEM software ANSYS to simulate. Using FEM to evaluate the strength of pressure hull, the FEM model of outer covering and stiffeners can use shell element to establish, but it may waste much computing time to calculate. Therefore, in this paper, we can evaluate more easier by making use of the idea of effective-width, and considering the stiffener/plating combined moment of inertia.

本文采用有限元素分析软体ANSYS进行求解，在有限元素分析的模拟上，外壳与环肋均可用壳元素建立一实体模型来分析，但是在模型的建立上过於复杂，在解析上也需要更多的时间来计算，因此本文采用有效幅度的观念，考虑环肋与壳板间之组合惯性矩，将环肋部分取梁元素来模拟，如此一来可简化建立模型的困难度，且大大的缩短分析的时间。

This operator will walk the list of elements in the Queue and print the value in each element. We'll print the elements inside a pair of brackets.

这个操作符将遍历 Queue 中的元素链表并输出每个元素的值，将在一对尖括号内输出元素。

It was found that the section was brittle. The scales of the pangolin were composed of the very thin prismy construction units and the folded units. The scales of the pangolin included such trace elements as S,Si,Fe,Al and Ca, besides the element of C,H,O and N. There were small amount of P element in the internal layer of the pangolin's scale.

结果表明冲击断口为脆性断口；穿山甲鳞片是由极细的棱柱结构单元和叠片结构单元混合形成的；穿山甲鳞片除含有大量的碳、氢、氧及氮元素外，硫、硅、铁、铝、钙5种元素的含量也相对较高，鳞片内层中含有少量的磷元素。

The line pencil equation for geometric elements in En is studied. From the direction number in the equation, the relative position between the elements and the projective space anp that between any two elements are analyzed.

本文系统地研究了E~n中几何元素的线束方程，由方程中的方向数分析几何元素对投影空间的相对位置和几何元素间的相对位置，规律性强。

Two finite element analyses were conducted. First, the poroelastic dynamic equations were transformed to Laplace domain and the Galerkin finite element approach is applied to derive the stiffness matrix of rectangular porous element for conducting the finite element frequency domain analysis.

为探讨空间声场之特性，本文将分析方法归纳为二部份，第一部份应用拉普拉斯转换后之多孔线性弹性动态方程以二维矩形多孔弹性元素及 Galerkin有限元素法推导并进行有限元素频域分析。

An element of a ring is said to be UR if it is the sum of a unit and a regular element and a ring is said to be satisfying DR-stable range if R has P-stable range and p is the set of all UR-elements of R.

当环的一个元素是一个可逆元和一个正则元之和，则称这个元素为UR。如果环R具有P稳定度且P是环中所有UR元素组成的集合，则称环R具有UR-稳定度。

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。
