It was found that increasing pressure for blank can improve the compactedness of blanks so as to make foam aluminium materials with homogeneous pores. Foaming temperature, as one of the main influencing factors on foaming process, should be controlled higher than the melting point of Al or Alalloy to a certain extant in order to keep a reasonable viscosity. Thus, the foam aluminum with homogeneous pores and high porosity is available. As shown by experiments, such materials should be made on conditions that they shall be protected with molten salt under 300?MPa pressure at 675～680?℃.

研究了粉末冶金法制备泡沫铝材料的方法讨论了发泡过程中的保护方式、制坯压力、发泡温度等参数对泡沫铝体积质量、孔隙率、孔结构的影响，并对发泡机理进行了探讨增大制坯压力使得金属坯致密，可以得到孔结构均匀的泡沫铝材料；发泡温度是影响发泡的主要因素之一，发泡温度控制在高于铝或铝合金熔点，同时保持熔体具有一定粘度的范围内，能够得到孔结构均匀、高孔隙率的泡沫铝材料实验结果表明：采用熔盐保护方式，在300MPa的压力下，温度在675～680℃时，可得到孔径均匀、孔隙率高的泡沫铝材料。

Cribriform epithelial stomata were seen mostly in 1.5-month old rats.

筛状囊上皮孔主要存在于1.5月龄大鼠的松果体囊上皮，是由许多密集排列的囊上皮细胞周边部细胞膜凹陷形成的圆形孔洞，筛孔直径200—500nm；喇叭口状囊上皮孔见于1.5月龄和12月龄大鼠的松果体囊表面，由相邻上皮细胞向松果体内部凹陷，形成圆形或椭圆形开口，孔径1～4脚。

In the manufacturing process, the fact that self adhesive stamp paper is thick, sticky perforated stamps processing methods and traditional significantly different, it is rarely used drilling holes in the teeth form (that is, to tear apart along the interval arrange hole formed as part of dentiform), while the vast majority of alignment with die-cutting mode continuous serrated, and closed shapes.

在制作工艺方面，由于不干胶邮票纸既粘又厚，所以齿孔加工方法与传统邮票明显不同，很少采用打孔方式形成孔齿（即沿间隔排列孔撕开所形成的齿形），而绝大多数采用模切方式形成线形齿边，呈连续并且封闭形状。

The epoxide groups of the column were modified by a reaction with diethylamine that affords ionizable functionalities required for ion exchange chromatography. The influences of the contents of the cross-linker and porogen on column pressure were investigated.

考察了交联剂及致孔剂用量对色谱柱压力的影响，发现：随着交联剂用量的减小，致孔剂用量的增大，柱压下降；当交联剂和致孔剂用量达到一定水平后，柱压变化不再明显，但柱体机械强度降低。

Ultra-micro structure of dolomite is investigated, we put forward that interface chemistry and geochemistry in nanometer hole should affect on the dolomization.

发现苏皖凹凸棒石粘土中白云石属于纳米颗粒，研究了白云石超微观结构特征，提出纳米孔界面化学和地球化学对白云石化的可能影响，初步模拟实验验证白云石化与纳米孔界面化学、纳米孔地球化学的关联，白云石交代过程中成分转化和结构转化的多步骤过程。

And for the stress in the directional direction, which is imposed on the lathe-bed, the bending plane is an epiplastron, therefore, the batten wall pore should be designed in the epiplastron.

而当孔的位置是位于弯曲中性轴附近的时候，其对弯曲刚度的影响比较小，而当其远离中性轴即靠近边缘的时候，对弯曲刚度的影响就越大，所以应该将板壁孔布置在弯曲中性轴附近，这样可以减少孔对床身刚度的影响。

Both the HepG2 cells and L-O2 cells have the expression of RhoA protein. However, the expression level of RhoA in HepG2 is much higher than that in L-O2. we also discover that the number of HepG2 cells mults more greatly with the detection of Millicell cabin than that of L-O2 cells through the hole, and that the number of HepG2 cells mults obviously and predominantly if added to RhoA excitomotor and decreases, obviously if added to RhoA antagon.

RhoA蛋白在HepG2及L-O2两株细胞中均有表达，但肝癌细胞株HepG2的表达量远远高于正常细胞株L-O2；通过Millicell小室检测，发现HepG2细胞通过细胞小室虑孔的细胞比L-O2细胞明显增多；HepG2细胞在加入RhoA激动剂后通过细胞小室虑孔的细胞显著增多；HepG2细胞在加入RhoA拮抗剂后剂通过细胞小室虑孔的细胞显著减少。

Corporation produces the round hole, the superfine pore and each kind of heteromorphous hole spurt the screw stock, to cast take the lead, the clean needle and the spinning module are suitable for the polyester fiber, the polypropylene fiber, the polyamide fiber, the ammonia black silk ribbon, the acrylic fibers, the adhesive-bonded cloth, compound spin, the PVC rug and so on.

公司所生产的圆孔、超细微孔和各种异形孔喷丝板、铸带头、清洁针及纺丝组件适用于涤纶、丙纶、锦纶、氨纶、晴纶、无纺布、复合纺、PVC地毯等。

Pistillata. However, the mean growth rates of S. pistillata in two mesocosms at 25℃ were significantly different. The mean growth rates of S. hystrix in two mesocosms at 28℃ were significantly different and did not show a consistant relationship compared to those of S. pistillata. The mean growth rates of S. hystrix in two mesocosms at 20℃ were significantly different, but those of S. pistillata were the same.

在25℃的2个生态箱之间，尖枝列孔珊瑚的平均生长率相似，并且大部份都显著高於萼柱珊瑚，而萼柱珊瑚的平均生长率则显著不同；然而，在28℃的2个生态箱之间，尖枝列孔珊瑚的平均生长率变异较大，与萼柱珊瑚的平均生长率比较并无一致的趋势；在20℃的2个生态箱之间，萼柱珊瑚的平均生长率相似，尖枝列孔珊瑚却有显著不同。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.
