难通过的

According to the classifing method of Geldart,ultrafine powders belong to group C particles.It is difficult to fluidize because of such cohesiveness.However,it was discovered recently that some powders can be fluidized smoothly through forming larger agglomerates at high gas velocity,and the fluidization quality of some powders can be improved by external force.

按Geldart的分类法，超细粉属难流化的C类颗粒，但近年来的研究表明，某些超细粉在高气速下可以形成较大的聚团，而以聚团形式实现平稳流化；对在高气速下难以流化的超细粉，人们通过引入外力场等方法来改善其团聚特性，提高流化质量。

The structural parameters of PNHAAs, such as the the maximum N-NO2 bond length, the least N-N Mulliken population, the least negative charge on the nitro group (QNO2) and OB100, were studied to predict their relative stability or sensitivity (the easiness for initiating a detonation, high sensitivity means low stability).

通过研究PNHAAs的结构参数，如N-NO2最大键长、N-NO2键的最小Mulliken集居数、-NO2所带最小负电荷、氧平衡，预测了10个标题物的相对稳定性或感度(起爆的难易程度。感度越高，化合物的稳定性越低)。

Through the synthetically analysis of the historical origins and evolution of the Quebec issue,the author holds that the two referendums in history and the defeat of Parti Quebecois in the provincial cabinet reshuffle in 2003 shows that the anti-separatist is getting domination gradually and it is hard for Quebec to separate from Canada. However,the Q...

作者通过对魁北克问题的历史渊源及在当代的演进综合分析后认为，魁北克历史上的两次全民公投及魁北克人党在2 0 0 3年省政府改组中败北表明，反对分离的主张正在逐步扩大优势，魁北克分离梦难圆；但该问题仍将是影响加拿大联邦构建和英、法裔族际关系的不可忽视的因素。

In order to obtained the six-membered ring compound and a thorough assignment of the spectra, and further to prove that the six-membered ring compound was formed from the hydrogen transfer, the compound N-butyl-4-(N-methylphenylamino)-5-amino- 1, 8-naphthalimide 6 was designed to obtained with N-butyl-4-bromo-5-amino-1, 8-naphthalimide and N-methyl phenylamine as the starting material. However it was difficult to obtain the desired product as the different solvent giving the different products except the desired product.

为了能够得到六元环化合物作为定标的物质及其确切的谱图分析结果，并且为了进一步证明由五元环产物通过氢转移得到六元环产物的正确性，设计用N-丁基4-溴-5-氨基-1，8-萘酰亚胺与N-甲基苯胺反应生成N-丁基-4--5-氨基-1，8-萘酰亚胺6，结果发现这种方法很难实现，选择不同的溶剂会生成不同的产物，却都不是目标产物。

In this paper, chemistry composition, fiber morphology and pulping property in Solidago canadensis were analyzed and determined preliminarily. The results showed that the content of holocellulose was 81.86%, the content of cellulose was 42.63%, the content of lignin was 18.86%, it is feasible for using Solidago canadensis pulping based on it's chemical composition. The ratio of fiber length to width in Solidago canadensis was 36.67, the average length of fiber was 440 μm, and the length of fiber was too short to pulping. The ratio of wall thickness of fiber cell to lumen diameter was 0.34, and it was smaller than that of other woody fiber. In this experiment, four different methods of pulping were as follows: kraft-AQ pulping Ⅰ, kraft-AQ pulping Ⅱ, alkaline pulping, alkaline sulfite adding AQ pulping, but it was difficult for lignin removal in Solidago canadensis.

通过对一枝黄花的化学组成、纤维形态以及制浆性能进行初步探索，结果表明：(1)加拿大一枝黄花的综纤维素含量为81.86%，硝酸乙醇纤维素含量42.63%，木素含量18.86%，由化学组成看，加拿大一枝黄花是比较适宜制浆造纸的；(2)加拿大一枝黄花纤维的长宽比为36.67，纤维平均长度为44μm，从纤维长度来看，加拿大一枝黄花的纤维较短，不适宜制浆，其纤维壁腔比0.34，和其它速生材相比较小；(3)采用4种碱法制浆方案，硫酸盐蒽醌法Ⅰ，硫酸盐蒽醌法Ⅱ、烧碱法、碱性亚钠＋蒽醌法，结果显示，加拿大一枝黄花的木素非常难脱除。

Acetic acid, glucose and starch (ratio=3:1) as well as starch and peptone (ratio=3:1) were used as main sunbstrates for the calcium-containing wastewaters, which represented the wastewaters containing acidified, unacidified and unliquefied organic compounds, respectively.

本研究分别采用以乙酸、葡萄糖＋淀粉（质量比3∶1）、淀粉＋蛋白胨（质量比3∶1）为底物的含钙合成废水，分别代表已经酸化的有机废水、易酸化的有机废水和难酸化的有机废水，通过在UASB反应器中的运行，研究了厌氧生物过程对高钙废水去除作用、去除机理以及重要的影响因素。

Sewerage pump pool must be installed at lower place,designed for discharging the castoff that producted by men in time.all the live draining water from the basement,such as basin,commode,washer machine,fabric pool,shower bath and bathtub so on contact with the sewerage pump pool ,and than drain into sewage well outside by passing through the watershoot,the pump pool should not have water ,or it will drunk the pump machine bad,make which can not operate normally.

对我来说有点难，请高人帮忙看看如何翻！急！污水泵池是为了及时排出生活中所产生的废弃物而设计的，必须安装在较低的位置。地下室所有的生活排水，如：面盆、恭桶、洗衣机、墩布池、淋浴间、浴缸等设施的排水都要经过排水管道与污水泵相连接，再通过排水管道直接排至室外污水井，泵池内不应有水，否则会泡坏污水泵电机，导致电机不能正常运行。
