GnRH 1R neurons were found as early as on the first day of culture. During the 1st-3rd days in vitro, they grew fastest. The average growth rates of the perikarya and processes were 45 59μm 2/d and 19 39μm/d, respectively.

Our results revealed that TGF-β1 at 1 ng/ml induced collagen deposition of HSC-T6 cells (145 ± 5 % of controls), and pre-exposure of cells to curcumin (1.25~10 μM) inhibited the stimulatory effect of TGF-β1 in a concentration-dependent manner. Curcumin (10 μM) significantly reduced the TGF-β1-induced collagen deposition (97 ± 7 % of controls) without cytotoxicity in the MTT assay .

我们的结果显示，1 ng/ml 浓度的TGF-β1可以有效地增加星状细胞对胶原蛋白的制造(达控制组的145 ± 5 %)，而在预先投予浓度范围为1.25~10 μM的姜黄素后可对TGF-β1引起的刺激反应产生浓度效应的抑制作用；姜黄素在浓度10 μM下可明显地抑制TGF-β1引起的胶原蛋白沉积(达控制组的97 ± 7 %)而不致产生细胞毒性。

Under conventional N fertilization and irrigation condition, N2O emissions during 2001-2002 and 2002-2003 in winter wheat and summer maize rotation system were 1959 g N hm-2 and 1250 g N hm'2, respectively; and 68%-86% of N2O emission occurred in summer maize growth season, the emissions mainly occurred in 2 weeks after N fertilization and irrigation. The highest flux rates were 5.06 mg m-2 d-1 and 5.60 mg m-2 d-1 in the rotation period of 2001-2002 and 2002-2003, which were happened at the ten-extended leaf stage in summer maize season when top-dressing N fertilizer was applied.

In this study, a commercial CAD/CAM Software is used to plan and generate the multi-axis tool path, and a table rotating/tilting type five-axis machining center is used to perform the experimental machining operation. The material of the die studied is NAK 80 die tool steel, and the geometries are modeled as concave and convex spherical surfaces. Milling parameters considered are spindle speed, feed rate, and different types of cutting tool path. The experimental results show that the surface roughness for concave spherical surface is about 0.247 μm and roundness is about 0.0283 mm and the surface roughness for convex spherical surface is about 0.250 μm and spherical roundness is about 0.0551 mm under the cutting conditions mentioned in this study.

A polycapillary X-ray lens with spot size of 41.7 μm was applied to focus original X-ray and a slit of 50 μm was located in front of the detector to improve angle resolusion.

为了提高入射X射线的强度并提高系统的空间分辨率，选用焦斑为41.7 μm的会聚透镜对原级X射线进行会聚，并在探测器前加上50 μm的狭缝以提高掠出射角扫描的角度分辨率。

Taking no account of aberrations,the optical spot size of the lens whose diameter is 1.80 mm is 1.2 μm.Compare the measurement value which is 1.5 μm with the theoretical one,they are almost identical with each others.It also proves the theoretical analysis is reasoned.
