The effects of variable properties on flow and heat transfer were also studied. 1. SIMPLEC algorithm was used to simulate the laminar natural convection flow in horizontal concentric annuli with the assumption of constant properties. Numerical studies range are as follows: Ra〓 number 100～10〓, radius ratio 1. 2～10.Velocity and temperature distribution profile and the heat transfer result were derived. The comparison of heat transfer results under the boundary condition of constant heat flux and constant wall temperature was also made.

对水平同心套管内层流自然对流采用SIMPLEC算法进行了数值模拟，在〓，半径比1.2～10范围内使用定物性假设进行了计算，得到有关温度和速度的分布以及相应的换热结果，并比较了内壁面分别处于定热流和定壁温条件下换热结果的差异，根据换热计算的结果整理并拟合有关的换热关联式。

根据鄂西铁矿石的特点进行了选矿药剂及相应的浮选和絮凝选矿工艺的研究，研制成功了RD-31捕收剂和DA-18选择性絮凝剂，采用磁选-脱泥-反浮选工艺流程，对武钢矿业公司科技处提供的鄂西铁矿混合矿样(WE-1样)进行

A: I am Ra. Many of those seen in your skies are of the Orion group.

A ：我是拉。许多在你们天空可见的物体来自猎户集团。

In this deposit, ore bodies exist in the stratoid form and are c ontrolled by thrust faults. The host rocks are limestone in Bolila Formation of Late Triassic Jiezha Group and in Gadikao Formation of Early-Middle Permian Kaix i nling Group, with strong dolomitization and weak silicification. Minerals are ra ther simple and consist of sphalerite, galena, pyrite, calcite, dolomite and barite. The important ore textures are colloforms such as framboid and crust and xenom orphic grains, and the ore structures are in disseminated, brecciated, veinlike and lumpy forms.

东莫扎抓铅锌矿床矿体呈似层状展布，产状严格受到矿区逆冲断层的控制，赋矿围岩为上三叠统结扎群波里拉组灰岩和下-中二叠统开心岭群尕迪考组灰岩，发育强白云石化和弱硅化，矿物组合简单，主要为闪锌矿+方铅矿+黄铁矿+白云石+方解石+重晶石，矿石结构以皮壳状、草莓状等胶状结构和他形粒状结构为主，矿石构造为浸染状、角砾状、团块状和脉状。

The modulation of sound properties over a wide range of time scales is one of the most obvious characters of Oscine passerine\'s vocal, whose song contains many different kinds of syllables that consist of many more multiple song phrases. In oscine passerine, ipsilateral projections of RA to NXIIts innervates the ipsilateral syringeal muscles exactly, and thus they have strong ability of vocal control with variable tones, high frequency and higher lever of quality.

鸣禽鸣啭的最大特点之一便是其单次鸣唱时间长，鸣唱所包含的音节数量和音节种类繁多，因而由这些音节所组成的句型结构也是复杂多样富于变化，且由于NXIIts严格的侧别控制(每一侧核团只支配同侧鸣肌)，使其具有更强的控声能力，其鸣声音调变化幅度大，频率高，品质因数大，音色好，因而其鸣声也悦耳动听。

A: I am Ra. Again we oversimplify to answer your query.

A ：我是拉。再次，我们很简要地回答你的询问。

RA: If they overstay, they could be subject to arrest and deportation.

亚律师：一般如果是逾期停留的话，可能遭受被逮捕和遣送出境的命运。
