The so called indirect integral operation means that Eular angles can be gotten from the direction cosine matrix which is received by the integral operation of quaternions or direction cosine.

飞行器导航中，姿态角的获取可以通过直接或间接的积分运算求得的，所谓间接获取即是指通过四元数或方向余弦的积分运算求得姿态矩阵，再从姿态矩阵中提取姿态角。

The former is to prepare polymolybdates coordinated' directly by organic ligands using Na2MoO4 and MoO3 precursors; The latter plays emphasis on exploiting a simple and effective routine to synthesize Keggin polytungstates in which the transition metal or Si acts as the heteratom by reaction precursor Na2WO4.We have synthesized a 4,4'-bipyridine bridging dumbbell-like polymolybdates a metatungs...

前者主要是制备有机配体键合的多金属钼酸盐；后者重点是探索出一个简易、有效的合成过渡金属或主族元素硅作杂原子的Keggin多金属钨酸盐的方法，然后通过变换过渡金属或有机配体的种类探讨对产物结构的影响，再对所得化合物的结构和组成通过物理测试手段进行表征，同时研究其在光、电、磁等方面的性质。

Do not worry, I left the baby at birth not passed, only 42 days passed, to about 60 days out from the left ear in a large piece of cerumen, your baby is not the ears, there are things you bring your baby to check yourself.

别着急，我的宝宝出生时左耳就没通过，42天时才通过的，到了60天左右从左耳里掉出一大块耳屎，你宝宝是不是耳朵里有东西，你再带宝宝去检查一下吧。

The fire's worst scars were effaceable by a comprehensive program of reforestation; a signal too loud to be erasable in a single pass through the erase head .

最严重的火灾痕迹可以通过全面的再造林计划予以消除；太大了的声音不能通过消音磁头一次给抹去。

The merger, to be effected through SP Telemedia acquisition of TPG for an acquisition price of $150 million in cash, to be funded through debt, plus 270 million SP Telemedia shares.

合并后，要通过sp电信收购TPG的收购代价1.5亿美元的现金，以资助是通过债务，再加上2.7亿sp电信的股份。

The method takes amorphous silica as silicon source and by the steps of soaking, baking, Fe nano particles is implanted, amorphous silica implanted into Fe nano particles and Alpha germanium oxide are mixed and grinded, the obtained mixture is gas-solid treated by organic amine, so as to obtain the silicon germanium oxide composite nano line.

该方法是以无定型氧化硅作为硅源，通过浸泡、焙烧植入铁纳米粒子，再将植入铁纳米粒子的无定型氧化硅和α氧化锗混和研磨，通过有机胺的气-固相处理，最终获得硅锗氧化物复合纳米线。

In the traditional GSM network planning, the revised Hata model serves as the prototype, and the coefficient in the model formula is tuned according to the data obtained in the radio propagation feature test specific to local actual radio environment, so as to obtain the propagation model for practical prediction. A common digital map only contains the clutter information and the digital terrain model information. So the building designers cannot fully allow for the influence of radio propagation, and can only estimate the influence on the building roughly from a traditional perspective, e.g., consider the influence of different clutters through certain clutter offset.

在传统的GSM网络规划中，一般都以修正的Hata模型为原型，再利用规划软件通过导入针对当地的实际无线环境做无线传播特性测试所得的数据对模型公式中的系数进行修正而得到实际预测用的传播模型，一般使用的数字地图仅包括地物信息和高程信息，因此建筑物对无线传播的影响无法充分考虑，只能从统计意义上对建筑物的影响进行粗略的估计，如通过一定的地物偏移来考虑不同地物的影响。

A simple polynomial approach for A Class of nonlinear system modeling is presented. By this, the input-output data are firstly changed into [0, 1] by using topological homeomorphism conversion; then an initial polynomial model is selected. The parameters of polynomial model are estimated by using recursion least squares method. A final polynomial model is obtained by repeatedly estimating parameter and eliminating redundant terms.

给出一类非线性系统的实现简单的多项式逼近的建模方法，在此方法中，将输入输出数据通过拓扑同胚变换，变换到[0，1]区间内，用多项式逼近的方法进行建模，对初始给定的多项式模型，通过反复的参数辨识、去除模型中的冗余项，得到非线性系统的多项式逼近模型，再利用拓扑反变换，将数据还原回原始数据区间。

The formed long and linear chain alkyl benzene changes into benzene methyl and alkene through β-scission and monomolecular homolysis, and then benzene methyl shifts to the position of α-Carbon in the long chain alkyl benzene through H-transfers.

已形成的长直链烷基苯通过β分裂、单分子均裂形成苯甲基、烯烃，苯甲基通过氢转移到长链烷基苯的α碳上，烯烃再与α碳结合形成带支链的烷基苯。

To which let me add, that he who appropriates land to himself by his labour, does not lessen, but increase the common stock of mankind: for the provisions serving to the support of human life, produced by one acre of inclosed and cultivated land, are ten times more than those which are yielded by an acre of land of an equal richness lying waste in common.

对这一点让我再补充一下：谁通过他的劳动占有土地，不是减少而是增加人类共同的储蓄；因为这些服务于人类生活的物品，通过圈入和开垦一英亩的土地所提供的，将十倍于同等肥沃而处于共有的荒废状态的一英亩土地。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
