难通过的

Finally, by means of analysing and analogizing the tendency of dynamic impedence of soil against the circular frequency, a simplified model of soilstructure system is proposed.

最后，本文通过对大量地基动力刚度和阻尼的计算结果的分析，引入了等效刚度质量和等效阻尼质量的概念，从而简化了土—结构体系的运动方程，建立了一个简化的等效模型。在此模型的基础上，使得原本在领域内很难求解的方程可以在时域内进行求解。

Wastes are inevitable, but can be an effective way to reduce waste by the quantity and the resulting pollution, innovativeink liquid、cleanser, a MOP, these different kinds of waste contains a lot of organic solvents, not only pollute the environment, but also cause danger to human health, and so these three challenging rejectamenta bridleon treattheir.

废料的产生是不可避免的，但可以通过有效途径减少废料的数量以及所产生的污染，油墨、清洗剂、抹布这几种废料含有大量的有机溶剂，不仅污染环境，还会危害人体健康，因此对这3 种难处理的废弃物要谨慎对待。

The hard and insolvable white particle s formed in the brine were composed of protein, which was not decomposed completely, and the tyrosine dissociated in the pa.

通过对白色物质的分析研究发现，这些白色物质的主要成分是酪氨酸和面筋蛋白，是由于面粉中的一些蛋白质未被彻底分解而与酱体中的部分游离氨基酸混合粘附于黄豆的表面，在盐水浸泡下形成较&硬&、难溶解的白点

A 156cm–1 red-shift is gained theoretically to demonstrate the presence of non-neglectable weak H-bonds and result in the discovery of the rarely reported trimeric H-bond, which consists of three independent hydroxyl donors and only one Cl– acceptor, in the field of crystal materials. We explained the relative weakness of this kind of hydrogen bond which may have a critical effect on the lattice symmetry and magnetic structure.

本研究据信为首次报道其振动光谱测量、解析结果，通过缜密解析意外发现了很少有人报道的三聚氢键的存在，为进一步理解其量子磁学特性提供的一条线索，同时也为验证难做的中子散射实验解析出来的晶体结构提供了很好的帮助。

Any person life is all impossible problem-free, the general meeting meets like this such adverse circumstance, windingly, difficult, but so long as we facing dangers and difficulties time, has the correct manner, has the full self-confidence, we can pass the difficulty, sees brightly.

生命是任何人都不可能解决免费，大会开会这样恶劣的情况下，windingly、难、但只要我们面临艰难险阻时，有正确的态度，有充分的自信，我们可以通过的难度，看到光亮。

The indirect of thruway traffic accident is greater than direct effect, and it is immeasurable at fieldwork. Based on vehicle microscopic behavior model, the paper developed the evaluation system for effect of thruway traffic accident by adopting object-oriented software technology.

城市快速路交通事故所产生的间接影响远远大于事故的直接损失，而其定量数据又很难通过实际的检测设备和测量手段得到，以车辆微观行为模型为基础，采用面向对象的软件设计方法，建立了城市快速路交通事故影响的微观模拟评价系统。

Novelist adopted of the way " Feminized the other"——By feminized the other force which is originally powerful and difficult to conquer, the first military confrontation change into a gender confrontation, thus Included into the marriage structure which implied power order.

小说家们通过&他者女性化&的方式——即将原本强大、很难征服的他者势力女性化，把最初的军事对峙转化成一种性别对峙，从而纳入到暗含权力阶序的婚姻结构中来。

That question is indeed the most difficult to answer and will likely be based on your current experience in the marketplace both in comparing this property to others and weighing your experiences with multiple offer scenarios, gazumping, and lost bids.

这个问题确实是最难回答的，可能需要基于您对当今房产市场的经验。不仅通过和其他房产的比较，也基于您过去在对不同情形下积累的经验，如同时面临多个买家、卖家房价谈妥后又抬价改售以及落标的情形。

So long as your computer to do the basic security configuration, it is difficult to hackers through 4899 to control you.

所以只要你的电脑做了基本的安全配置，骇客是很难通过4899来控制你的。

In many xerophytes and in some conifers of cooler climates, where soil water may be difficult to obtain in winter, the guard cells-and hence the stoma-are sunk in pits in the epidermis, often protected by hairs form passing air currents. TRANSPIRATION rates are thus greatly reduced, while allowing gaseous exchange for photosynthesis.

一些旱生植物和寒冷气候带的针叶树在冬季很难从土壤中得到水分，因此它们的保卫细胞和气孔在表皮上下陷成为气孔窝，常被表皮毛保护，可以在满足光合作用所需的气体交换的同时防止通过的气流带走大量水分，大大降低了植物呼吸率。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
