And the development and formation of the sieve tube elements of the different cultivars were influenced by the different levels of B: the sieve tube elements of the two cultivars were not formed at the level of 0.001mg/L; At the level of 0.01mg/L, the sieve tube elements of the high efficiency (Qingyou 10) cultivar could be formed, but the structure of the sieve tube elements was not complete, and the abruption and differenciation of the sieve tube elements of the low efficiency cultivar were inhibited, they were not formed; At the level of 0.01mg/L, the sieve tube elements of the two cultivars were formed.

不同硼水平下，不同硼效率甘蓝型油菜品种根尖筛管分子的发育与形成受到影响：硼浓度为0.001mg／L时，两个油菜品种都不能形成筛管分子；硼浓度为0.01mg／L时，硼高效品种青油10号筛管分子可以形成，但结构受到破坏，而硼低效品种Bakow筛管分子的分裂与分化受阻，几乎不可能形成成熟的筛管分子；硼浓度为0.5 mg／L时，两个油菜品种都能正常生长发育。

The main bearing structures were destroyed in blasting, such as pier, vault and spandrel.

在爆破过程中主要破坏其主要承重结构，如桥墩、拱顶和拱脚。

In Chapter Ⅴ, we present a theoretical study of the dielectric behavior of cell suspensions by the Bergman-Milton spectral representation of the effective dielectric constant.

计算还发现即使在系统色散参数趋于零的情况下，表面周期结构也将会引进有效的色散关系，破坏表面模振荡频率的简并。

Stability of a highly-jointed cut destructed slope in Guangdong province is analyzed with stereographic projection method in the paper based on detailed geological investigation.

依据地质调查数据，运用常用的边坡岩体结构分析法和赤平投影方法，对广东某省道公路一处曾发生滑坡、崩塌破坏的节理化岩石边坡的稳定性进行了分析。

In order to study the stability of stratified rock slope in Zhu-Cheng road and its reinforcement method, the potential deformation and slipping mechanism of slope were analyzed using insitu-investigation and stereographic projection analysis method. The numerical calculation model for stratified rock slope was founded with UDEC software. The deformation of rock mass was analyzed in the excavation procedure, and the long-short compound bolt reinforcement structure was proposed according to the deformation failure mode of stratified rock slope.

摘 要：为了研究竹城公路层状岩质边坡的稳定性及防治措施，通过现场调查和赤平投影分析边坡潜在变形滑动机理；利用UDEC软件建立层状边坡数值计算模型，分析开挖过程中岩土体的变形情况；根据变形破坏模式提出层状岩质边坡的长短锚杆交替复合支护结构。

Therefore, it is further proved that local failure theory is correct and weak structural plane will control the stability of slope.

从而进一步证明了局部破坏理论的正确性和边坡软弱结构面是控制边坡稳定的关键因素。

Submicroscopic structure revealed that the structure of chloroplasts and mitochondria was damaged.

亚显微结构观察显示，叶绿体、线粒体遭到破坏。

Detailed researches are implemented to behavior of superincumbent strata in mining 45 degree coal seams using horizontal section top-coal caving in this paper.

本文针对45°特厚煤层水平分段放顶煤开采后的上覆岩层移动破坏规律进行了深入研究，指出45°特厚煤层开采后老顶破断后在一定层位形成了沿倾斜方向的铰接岩梁结构，即倾斜岩梁。

This paper analyses the conditions of the municipal public safety in the city,pointing out the municipal public safety management in the city,and the network of the municipal public safety management including its functions,techniques,supportable policy and the mode of operation.

针对城市的快速发展，各种突发性自然灾害或人为破坏事件增多，在充分分析城市公共安全管理现状的基础上，提出了城市公共安全管理网络平台建设，并对其总体结构，各自功能，技术、政策支持及运行模式进行了深入论述。

Does not fear the fire: The lumber has the carbonization effect, when meets the fire, the outer surface of wood surface will form the carburization zone, its low conductivity may prevent the flame to spread inward effectively, thus guaranteed that the entire syntagma is not destroyed for a long time.

不怕火灾：木材具炭化效应，遇火灾时，木表面会形成炭化层，其低传导性可有效阻止火焰向内蔓延，从而保证整个结构体在很长时间内不受破坏。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。
