使增加密度

The study shows that the adoption of this new technique makes the charge more compact and brings about a satisfactory supplement of liquid ex- plosives,thus increasing the charge density,which is most advantageous to the crimination of pores,cavities,gaps at the bottom and in loose struc- tures.

他强调，氘是必不可少的，他的做法，增加一倍，密度的氢气，使其成为强大的两倍。

In case the electron transfer increases the outer electron cloud density of active metal, metal catalyst would be liable to be poisoned by sulfur.

如果这种电子转移的结果使活性金属的电子云密度增加，则金属型催化剂抗硫性就会下降。

The experimental results show: the flattop phenomenon on the diode voltage pulse was very apparent for using the carbon fiber cathode, that is to say, the pulse duration of the diode voltage was widened; moreover, under the condition of the same power of microwave, the pulse duration of the out-put microwave was prolonged by about 30%; the peak power of the microwave was enhanced by 3dB.

The paper fristly analyzed the reason of mine air reversing in Liangbei coal mine of Xinlong Coal Industry Corporation,which based on mensuration of mine ventilation resistance and spontaneousness wind pressure,and then the measures of preventing the air reversing was put forward.

在对新龙矿业集团公司梁北煤矿的矿井通风阻力测定和自然风压测量的基础上，找出梁北煤矿2007年1月气温突降后所引起的主井风流反向的主要原因，推导出导致风流反向的基本条件，提出在副井至-550 m运输石门之间增加调节设施以增大副井的风阻、增大主要通风机机械风压、在主井下安装压风机人为增大主井的机械风压、减少主井附近热源、对主井的风流进行降温处理和对副井的进风流进行预热以减少主副井之间的风流平均密度差等防止风流反向的控制措施，从而使主井恢复正常的进风状态，消除了矿井安全生产的严重隐患

ANSYS is a finite element simulation software used to simulate the temperature field in selective laser sintering.By using the ANSYS parameter design language,the density of the thermal flow,the velocity and the path of scanning can be controlled.The effect of the scanning path on the temperature field in the SLS process is studied. Balling,which occurs at the end of the scanning line,is caused by the dissymmetric temperature field and the great temperature gradient.

利用有限元分析软件AN SY S，对激光烧结温度场进行了数值模拟，建立了激光烧结薄板的温度模型；运用APDL语言控制热源的热流密度、移动速度以及扫描轨迹；研究了激光行程对烧结温度场的影响，扫描端点温度场的不对称及较大的温度梯度造成了端点球化现象；激光扫描线间的耦合作用使端点球化现象随扫描线的增加而逐渐显著。

APUHD was prepared with PEPUD acted as emulsor and reactive seeded emulsion in polymerization of acrylate monomer.

利用可聚合自乳化聚氨酯水分散体作为乳化剂和反应性的种子乳液与丙烯酸酯等单体共聚，其优点在于能调节聚氨酯水分散体侧链上参与共聚的双键数目，使聚氨酯和丙烯酸酯两相聚合物体系间直接化学键合增强，相容性提高，增加体系内部交联密度，合成得到具有核壳间互穿网络结构的丙烯酸聚氨酯杂合水分散体。

Can reverse JA-induced migration inhibition JA-treated cells also showed significantly higher adhesion to laminin In conclusion these results indicate a novel anti-tumor role of JA via reducing reorganization of cytoskeleton increasing integrin 3 expression and adhesion ability to inhibit tumor cells migration Furthermore immunofluorescence staining of phalloidin/actin indicated that JA-treated cells exhibited cytoskeleton rearrangement and significant decreases in the number and length of filopodia Activity of Rho-family small GTPases was detected by a GST-pull down assay and showed that GTP-loaded Cdc42 and Rac were decreased in JA-treated cells In the future we hope these findings will be helpful to further understand the mechanisms underlying tumor progression in oral cancer and subsequently improve the cancer prevention and treatment

以抗体阻断integrin ？3可以有效使OC2恢复被JA所抑制的迁移能力。细胞贴附实验指出JA能提高OC-2在laminin环境下的贴附能力。当我们进一步以免疫萤光染色观察细胞，发现在JA处理下的OC-2，其外形、细胞骨架和细胞边缘的filopodia的密度和长度明显减少，利用GST-pull down assay侦测到Cdc42-GTP和Rac-GTP的表现量降低。推论爵床素A可能透过刺激口腔癌细胞大量表现integrin ？3，使细胞贴附能力增加或是透过改变细胞骨架来降低细胞迁移能力。希望本研究对於JA所做的抗癌及抗转移效应评估能提供口腔癌治疗在研发上一些帮助。
