前线

The main cause of the forest fire is the whether factors such as drought, windiness and lighting strike.

Methods: Eight hundred normal cases were chosen randomly for study. Ultrasound was carried out in vertical section at xiphoid process, cross section at middle abdomen, and coronary section at the waist to detect the presence of AHV. The function site, number of AHV, caliber, flow velocity and the angle between AHV and IVC were investigated.

随机选健康查体者800例行超声检查，取剑突下纵切、右腋前线纵切、横切和中上腹部横切、肋间斜切，观察AHV的汇入部位、走向、数量、内径及其与下腔静脉轴线的夹角及多普勒波形、流速等。

He gave the GIs "my most experienced armoured regiment, the Sherwood Rangers Yeomanry," told the American battalion and division commanders to get up front, and returned to his headquarters.

霍罗克斯把"我最有战斗经验的战车团——舍伍德护林人团"*交给美军指挥，要求美军的营/师指挥官向前线前移指挥位置，然后他回了自己的指挥部。

For example, Pudovkin in the "end of St. Petersburg," one in two shots on such series: First performance of front line combat soldiers lay dying in the mud; the other is the performance that was wild excitement of the zaibatsu were fictitious in the skyrocketing stock market.

例如普多夫金在《圣彼得堡末日》一片中，有这样两个镜头的对列：一是表现在前线上作战士兵奄奄一息地躺在泥里；另一个是表现那些兴奋的发了狂的财阀们在暴涨的股票市场上买空卖空。

So, the aromaticity of acenaphthenyl groups in C_2 gum should be the least. In order to explain the reason, quantum chemical calculation is utilized. The optimized geometrical structrures of condensed aromatics in C_1 gum, C_2 gum and C_3 gum are calculated at B3LYP/6-31G* levels. We find that some phenyl groups in acenaphthenyl groups are coplanar and have the largest conjugated structure.

为了解释其原因，我们利用量子力学方法进行了计算，研究了三种稠环基团在B3LYP／6-31G*基组水平下优化得到的几何结构，发现苊式多苯基苯基中的萘环和中间的苯环共面，电子离域性最大，而其他二者所有苯环都不共面，发生了明显地扭曲；同时，在优化几何结构的基础上，对三种化合物进行了前线分子轨道的分析，利用密度泛函理论方法(density function theory，DFT)计算了稠环基团的最高占有轨道和最低未占轨道之间的能量差，即能隙，发现C_2胶上苊式多苯基苯基的Eg最小，解释了C_2胶具有最好的辐射保护效果的原因。

In the collective life with the mankind, they are manipulator arm not just, car component is assembled in busy automation line; Also be Achillean steely soldier not just, the front position with the most dangerous development, they still can do all sorts of chore, can smile to ask you:"Happy today?"

在与人类的共同生活中，它们不仅仅是机械手臂，在繁忙的流水线组装汽车零部件；也不仅仅是刀枪不入的钢铁战士，深入最危险的前线阵地，它们还会做各种家务，会微笑着问你：&今天开心吗？&

When we were oblige d to evacuate Hankow and go into the hinterland to carry on and continue our resistance against aggress ion, the Generalissimo and I passed one of our fronts, the Changsha front.

我们被迫从汉口撤退，转入大后方继续抵抗侵略的时候，蒋委员长和我经过一处前线，就在长沙。

Most important, proven weapons— principally, insecticide-treated bed nets, other antimosquito strategies, and new combination drugs featuring an ancient Chinese herb— are moving to the front lines.

最重要的是，已经证实有效的武器，正朝对抗疟疾的前线移动，这些武器主要是含有杀虫剂的蚊帐、他的抗蚊策略，以及根据古老中国药草而来的新组合药物。

Molecular geometry,atomic net charge,constituents and energy of the frontier molecular orbital for eight alkylated arylamine anti-oxidant and anti-corrosive additive s have been calculated by density functional theoryat the 6-31G~* basis set level.

采用量子化学方法，在B3LYP/6-31G~*水平上对8种烷基化芳胺抗氧抗腐添加剂的平衡几何构型、净电荷及前线轨道组成和能级等进行了理论计算研究，探讨了这些化合物的结构特征。

The first hyperpolarizability and molecular frontier orbit properties of barbituric acid derivatives are studied at HF/6-31G level by coupled perturbed Hartree-Fock method.

采用耦合微扰方法在HF/6-31G水平上对巴比妥酸衍生物的第一超极化率和分子前线轨道性质进行了计算。

Lugalbanda was a god and shepherd king of Uruk where he was worshipped for over a thousand years.

Lugalbanda 是神和被崇拜了一千年多 Uruk古埃及喜克索王朝国王。

I am coming just now,' and went on perfuming himself with Hunut, then he came and sat.

我来只是现在，'歼灭战perfuming自己与胡努特，那麼，他来到和SAT 。
