查询词典 diffusive

For diffusive Predator-Prey model with Holling-Ⅲ functional response without time delay, shooting argument together with LaSalle's Invariance Principle and the Hopf bifurcation theorem are applied to prove the existence of traveling wave solutions and small amplitude traveling wave train solutions.

The diffusive XGPN shows cystic-solid multi-occupying with the whole kidney involved and kidney renal pelvis and calices enlarged. The lesions were extensive with unclear border which made the perirenal space dim renal fasciae thicken and with the abscess formation of psoas and abdominal wall.

弥漫型累及全肾，肾影增大，肾盂肾盏扩大积液，肾实质幕粥发囊实性占位，病变分界不清，向肾外扩展，肾周间隙模糊，肾筋膜增厚并累及腰大肌，腹壁脓肿形成；局灶型表现为肾实质内局限性占位，病灶区呈略低密度灶，增强后边界清晰，病灶内见环形强化，而略低密度灶者强化较明显，但仍低于肾实质。

The chemical structure of the product was characterized by means of the melting point and IR. The results show that tetraethylammonium bromide which was used as a phase transfer catalyst in this reaction had optimization effect on the interfacial diffusive reaction of BTC and PNP. Higher concentration of sodium hydroxide, lower temperature and a higher dosage of BTC produced a small amount of 4-nitrophenyl chloroformate, while lower concentration of sodium hydroxide and a lower dosage of BTC made reaction incomplete, which affected the yield.

结果表明，在碳酸二（4-硝基苯基）酯合成中使用的相转移催化剂四乙基溴化铵对受界面扩散控制的BTC气与对硝基酚钠反应有良好的相转移催化效果；氢氧化钠质量分数较低时，酚钠盐向溶有BTC的油相扩散速度较小，较高时会产生氯甲酸对硝基苯酯；温度较低、BTC量较高时，会产生少量氯甲酸对硝基苯酯，BTC用量较低会使反应不完全，这些都影响着收率。

Joint effusion were in 5,the tibial ligament sprains in 2 and tears in 1,the fibular collateral ligaments sprains in 1,MR appeared contusive ligaments as irregular hyperitensity in swollen ligament,and teared ligament present as diffusive hyperintensity and total or partial interruption in the injuried ligaments.

其中关节腔积液5例，内侧副韧带损伤2例，部分撕裂1例，外侧副韧带损伤1例，损伤韧带表现为韧带不同程度增粗，正常低信号内出现不规则高信号；撕裂表现为韧带明显增粗，呈弥漫性高信号，韧带的连续性部分或完全中断。

MR of contusive ligaments appeared as irregular hyperitensity in swoilen ligament but their continuity was not disturbed and teared ligament presented as diffusive hyperintensity and total or partial interruption in the injuried ligaments.

损伤韧带表现为韧带不同程度增粗，但韧带连续性存在，正常低信号内出现不规则高信号；撕裂表现为韧带明显增粗，呈弥漫性高信号，韧带的连续性部分或完全中断。

Results Among 96 cases of CD117-positive GISTs, 94 positive for nestin (in amount of this 70 diffusive positive, 21 moderate positive, 3 local positive), the other two were negative. 4 of the 5 CD117-negative GISTs and 26 of 33 Schwannomas expressed nestin too, only 3 of 15 leiomyosarcomas showed focal positive for nestin. All oesophagus leiomyomas and fibromatosis of intestinal demonstrated negativity for nestin.

结果 96例CD117阳性的GISTs中，94例表达nestin，其中70例弥漫强表达，21例中度阳性，3例局灶阳性，仅2例阴性；5例CD117阴性的GISTs中，4例表达nestin；33例消化道雪旺瘤中26例表达nestin；15例平滑肌肉瘤中3例局灶表达nestin；10例食管平滑肌瘤、6例肠纤维瘤病均为阴性。

The most important character of such a problem is that the vapor makes not only a bulk motion under the pressure gradient with the whole gas phase together, but also a diffusive motion relativing to the incondensable gas.

这类问题的主要特点是蒸汽不仅随着不凝性气体在压力梯度的驱动下做整体运动，还有相对于蒸汽相对于整体运动的扩散运动。

As far as positive terms are concerned , economic globalization intervolve china into main stream of world economy, the changing track of foreign developing trade strategies clearly shows the determination of china to take part in economic globalization and display her active attitude to participate the international cooperation ; Entering into WTO makes china win the fairly competitive circumstance, decrease the trade friction and discrimination ; Economic globalization makes china face a new competition ,we have a big gap compared with other countries in trading systems and general competition which mind us to face reality and take active action to come over it ; Foreign direct investment ,its promoting function to the total volume of import and export of china shouldnt be ignored ,meanwhile , its diffusive effect of technology expedites industrial upgrade ; At last ,the keen competition makes entrepreneur innovate and invent.

经济全球化给中国开来了巨大影响，这种影响有积极的一面，也有消极的一面。从积极面来看，经济全球化将中国纳入全球经济发展的主流中，中国对外贸易发展战略变化轨迹清楚地向世人展示了中国参与经济全球化的决心和参与国际分工和合作的积极姿态；加入WTO，是中国赢得了公平竞争的国际环境，减少了贸易歧视和摩擦；经济全球化是中国面临全新的竞争，在贸易体制上和企业综合竞争力上，我国都与WTO成员国有一定差距，这些差距是我们正视现实，积极应对挑战，面对激烈的市场竞争，迫使企业积极创新，提高企业竞争力。
