本文研究了用连体四角锥碘化银为晶核制备类似于四面体碘溴化银微晶和用六方角锥碘化银为晶核制备片状碘溴化银微晶的方法，并对两种不同微晶的结构，形态和性能进行了比较和分

If the Dragon's Tail be with Saturn in Square of the Moon, and she Cadent, the Native will be consumptive, especially if from an Angle; but if besides it be in Square to the Lord of the Ascendant, he will be sickly and infirm all the days of his life, and if such Aspect happen in or from the sixth house, so much the worse.

若龙尾与土星同时刑月，月亮落在下降宫，则盘主易患结核病，尤其是当龙尾与土星落在四角之上；具备上述条件的命盘，若刑相位牵扯到命主星，则盘主一生多病且体质虚弱，若相位发生在6宫或来自6宫，则大凶。

But experts said that this is a deformational sheep, and the possibility to breed the 4-horned sheep is very small.

但专家断定这是一只畸形羊，繁殖出四角羊后代的可能性极小。

Result:The pollen is morphologically oblate, suboblate, spheroidal and prolate. The external sculpture is commonly reticulate, striate and echinulate.

结果：其花粉多为扁球形、近球形、三角形、四角形等；萌发孔为三孔沟、三沟、散沟等；外壁纹饰多为网状纹饰、条状纹饰、刺状纹饰。

A structured grid partitionfor full scale coal fired tangential utility boiler has been given in this paper. It hasa small amount of grids and can decrease false diffusion effectively as it is inagreement with fluid flow direction. Accurate simulating results can be gainedwith the grid partition. Inverse flows are captured near the wall at four corners incombustion simulating through the above grid and temperatures simulating agreewell with them measured.

对于大容量四角切圆锅炉的数值模拟，本文给出了一个可以有效减小伪扩散、流体流动方向与网格线方向一致、数目较少、计算精度较高的结构网格，该网格的数值计算结果清晰得捕捉到了四个角向火侧和背火侧靠近壁面处的小回流，而且计算温度与炉膛温度实测值较好的吻合。

Methods After the sample of Fenneropenaeus chinensis, Litopenaeus vannamei, Liza haematocheila, Acanthogobius hasta, Mactra veneriformis, Aloidis laevis, Ostrea denselamellosa and Fenneropenaeus chinensis was digested with concentrated hydrochloric acid, the lead content in marine products was measured by fluorimetric method and the results were compared with dithizone spectrophotometry.

采用湿式消解法对中国对虾、南美白对虾、梭鱼、矛尾刺虾虎鱼、四角蛤蜊、光滑兰蛤、密鳞牡蛎、中国对虾样品进行处理，采用浓盐酸作溶剂，荧光分光光度法直接检测铅含量，并与双硫腙光度法的测定结果进行比较。

卵经过卵壳腺时受精，受精卵外被一厚而坚韧的卵鞘，为黄褐色、椭圆四角形

At last, natural frequencies of practical pre-stressed composite space truss are tested with pulsatory method on construction site and its damping ratio is calculated, which gives another important data for engineering design. In addition, through the model experiment of pre-stressed rectangular square pyramid composite space truss, the correctness of characteristics of internal force and the feasibility of tension recovery method are proved.

最后，在工程施工现场用脉动法测试自振频率，并借助于振动衰减曲线和半功率点法计算出预应力组合网架——钢与混凝土的混合结构体系——的阻尼比，此又为工程设计提供了一理论依据；另外，通过正放四角锥预应力组合网架的模型试验，验证了结构内力分布特点的正确性以及张力松弛法的可行性。

The steel roof structure of Century Hall of People′s University of China is a normally placed pyramidic latticed frame with surrounding cantilevers.

中国人民大学世纪馆屋面结构采用四面悬挑的正放四角锥二层网架结构，跨中为三层。

This paper's conclusion includes several points: the contracting process of PSDY is a quadripartite relationship that is more complex than the "third party contracts". Differences in professional decisions and poor collaboration between the departments within the Department of Social Welfare leads to insufficient definition of service, makes effective contract management difficult, provides minimum protection of client accessibility.

透过深度访谈与档案文件分析，本文获得以下几项结论：地方政府少年安置服务的委外，是一个比第三方契约理论所描述的更为复杂的四角关係，公部门內部不同科室之间的成见与隔阂，使得受託者自主空间更大，有效的契约管理更形困难，而个案的服务近用性也更得不到应有的保障。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
