The results show that with the increase in milling time, the crystal sizes of W-Cu milled powder will be finer, while the undersaturation solid solution will generate, the crystal sizes of sintered alloy will grow up, holes will reduce and the relative density will reduce and approach to full density.

结果表明，随着球磨时间的增加，钨铜球磨粉末晶粒尺寸得到细化，且有不饱和固溶体产生；烧结合金晶粒尺寸长大，孔洞减少，相对密度增大接近全致密。

Intact phycobilisomes were isolated and purified from Porphyridium cruentum,a unicell red algae by sucrose density gradient supercentrifugence.

用蔗糖密度梯度超速离心的方法从单细胞红藻---紫球藻中分离纯化了完整的藻胆体。

Part Ⅰ: Brain structural abnormalities in patients with a first episode of major depression — An Optimized Voxel-based morphonmetry MRI study OBJECTIVE: We examined the structural difference in regional gray matter density between unmedicated patients with a first episode of major depression and healthy comparison participants in order to find the base of pathophysiologic mechanism in MD.

第一部分首发重性抑郁症患者脑结构磁共振异常的研究—基于体素的优化形态测量学分析方法目的：探讨首发、未服药重性抑郁症患者全脑灰质密度的异常变化，以揭示抑郁症患者病理生理机制的脑结构基础。

Numerical analysis of unit heat generation rate and thermal flux density is conducted. Results show that the chamber's boundary extermal thermal conduction is the primary factor that leads to temperature ununiformity distrubtion inside the chamber.

而单元生热率及热流密度的数值结果表明，腔体边界上的对外热传导是温度不均匀分布的主要原因。

Moreover, overpression of Wnt10b in the organ culture of vibrissae HF has been manipulated by infected the recombinant adenovirus expressed Wnt10b protein(Adwnt10b).

Ki67在毛母质中的表达变化规律以及在毛母质中的表达部位与Wnt10b具有一致性。2、我们对Wnt10b重组腺病毒进行了逐级扩增并应用氯化铯超高速密度梯度离心法纯化，病毒最终滴度达到109 PFU/ml；3、首次发现加入Wnt10b重组腺病毒可明显促进体外器官培养的触须毛囊毛干和内根鞘生长，这与本课题组在在体动物实验中发现的现象一致。

the in case there exists simultaneously the conditions of the quantity of rattus flavipectus and xenopsylla cheopis in the this en-demic region over70%of the total and the density of rattus flavipectus indoors over5%and the rattus flavipectus index of xenopsylla cheopis over,then it will anticipate an epidemic of plague.

家鼠鼠疫疫区黄胸鼠和印鼠客蚤占总数的70%以上，当室内黄胸鼠密度大于5%及黄胸鼠体印鼠客蚤指数大于1等三项指标同时成立是鼠疫流行前期的预兆。

EVA/LDPE/ CB conductive foam was made of EVA and LDPE as matrix,HG-1P CB and ACET CB as conductive filler,AC as foamer and DCP as crosslinker.

文章以乙烯-乙酸乙烯酯和低密度聚乙烯为主基体，特导炭黑(HG-1P)和乙炔炭黑为导电填料，偶氮二甲酰胺为发泡剂，过氧化二异丙苯为交联剂，制备了EVA/LDPE/炭黑导电泡沫复合材料。

The purpose of the paper is to build a module of small molecular receptor fragments charactering normal VLDL-R binding function and study the mechanism of VLDL-R binding to ligand.

建立具有正常极低密度脂蛋白受体结合功能的小分子受体片段模型并借助此模型研究VLDL受体与配体结合的作用机制。

The density, electrical contact resistance and hardness of these two alloys were tested. The results show that Ag and rare earth oxide appear in Ag-Y and Ag-Ce alloy after internal oxidation. The distribution of oxide particles is inhomogeneous and seriously conglomerated in Ag-Y2O3 and Ag-CeO2 sintered bulk, but they are dispersed and uniform in Ag matrix after severe plastic deformation. The relative densities of wire materials are larger than 99% and the electrical contact resistances are low (＜2.2 μΩcm).

结果表明：Ag-Y和Ag-Ce合金粉末经内氧化处理后生成Ag和稀土氧化物2种物相；Ag-Y2O3和Ag-CeO2材料烧结坯中氧化物颗粒分布不均匀且团聚严重，但材料经过大变形加工后，氧化物颗粒细小，均匀地弥散分布在银基体上；最终产品丝材的相对密度均达到99%以上，电阻率较低(＜2.2 μΩcm)。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
