CT images of the 6 UAs showed homogenous and low density in comparison with muscles. Of the 6 UAs, 2 (33%) were lobulate, 4 (67%) were regularly round or oval; 1 (17%) had bone septa, 2 (33%) had root resorption of the neighboring teeth, 3 (50%) had cortical perforation. All UAs showed well-circumscribed margins without soft tissue masses. Three UAs were examined by enhanced studies and showed mild to moderate enhancement of the wall. Of the 5 MAs, 3 (60%) showed low to intermediate density as compared with muscles, 2 (40%) showed homogenous and intermediate density; 3 (60%) had bone septa; 3 (60%) showed root resorption or destruction of the neighboring teeth. All 5 MAs were lobulate with cortical perforation, soft tissue masses, and ill-defined margins. All 3 MA5 examined by enhanced studies showed strong enhancement. CONCLUSIONS: SMAs are usually seen in middle-aged patients.

Results: 1 Intense ERα immunoreactivity localized in the hypertrophic and maturative layer, and some immunoreactivity was found in osteoblasts of mandible and temporal bone, while no immunoreactivity was found in the disc and synovium. 2 The expression of ERα in male rats TMJ cartilage was higher than that in female ones. 3 In the condyle cartilage of male rats, the density of ERα positive cells decreased with age, which kept stable after 16 weeks of age. 4 In the condyle cartilage of male rats, the density of ERα positive cells was stable from birth to 8 weeks, but decreased from 16 weeks to 12 months, while the density in 18-month group recovered to the level of 8 weeks. Conclusion: TMJ is one of target organs of estrogen, and ERα plays an important role in the effect of estrogen on TMJ.

结果：1TMJ中ERα主要在髁突软骨的肥大层和过渡层表达，下颌骨和颞骨的骨细胞也有少量表达，而关节盘、滑膜中几乎无表达；2雄性SD大鼠髁突软骨中ERα的表达明显强于同龄的雌性大鼠；3在雄性大鼠TMJ髁突软骨中阳性细胞密度随年龄增长逐渐降低，16周以后逐渐维持在相对稳定的水平；4雌性大鼠从出生后到8周龄阳性细胞密度基本稳定，在16周龄至12月龄年龄组阳性细胞密度显著降低，而在18月龄后又恢复到8周龄以前的水平。

The results show that under the action of the ponderomotive force of the coupling laser, there are a larger divergence of the density profile of the electron and ion in the laser-plasma than that without Compton scattering, the faster change of the electron density than the ion density, and the stronger electrostatic field than that without Compton scattering.

研究发现，在耦合激光的有质动力作用下，电子密度分布和离子密度分布比Compton散射前的偏离更加严重，电子密度的变化比离子密度的变化更快，产生的静电场更强。

By non-enhancement scan, 12 cases showed low density mass, 4 cases equal density mass, 1 case slightly high density mass, and 2 cases stippled calcification mass. By enhancement scan, 13 cases showed inhomogenous enhancement in cortical phase, 2 cases showed slight to moderate enhancement. Another 2 cases of small cystic RCC presented enhancement of wall with nodules and the partition. The enhancement of all tumor cases faded away in the following parenchymal phase and pyelographic phase, demonstrating some degrees of "fast washing out" phenomenon; 4 cases presented with pseudocapsule. The reconstruction of 17 "MPR/MIP" and 9 "VR" showed clearly the relations of kidney vessels, tumors and neighbor tissues and accessory renal arteries were founded in 2 cases.

It is well known that the large lattice mismatch (16%) and thermal expansion coefficient mismatch between GaN and sapphire substrate are the main origins of TDs. By new growing technique of LEO, we acquired high quality GaN films almost free of TDs. The stress characteristics in GaN films with MLTB growing technique is dependent on growing systems and conditions, and the changes of stress and dislocation density are rightabout; Combining buffer layers of high temperature and low temperature is first developed to growing GaN films with low dislocation density, and the mechanism of lowering TDs density is that the first buffer layer of high temperature can make nuclear in second buffer layer of low temperature bigger. This technique also can restrain yellow luminescence effectively.

众所周知，晶格失配和热应力失配是GaN异质外延中位错产生的主要原因；为此，我们对几种降低缺陷的MOCVD外延生长方法进行了新的尝试，其中尝试了侧向外延生长技术，得到了低位错密度（小于10〓/cm〓）、高质量的GaN外延层；尝试多低温缓冲层法，发现材料中的应力特性与生长系统和生长条件有关，材料中的应力与位错密度按相反方向变化；首次尝试高低温联合缓冲层法，材料中高温缓冲层可以使随后的低温缓冲层中成核颗粒增大，从而导致随后高温GaN外延膜中位错密度降低，并且能够有效地抑制黄光峰。
