初喷接触面粘聚力和摩擦角强度一定时候，初喷破坏区随初喷厚度的增加而减少；接触面强度变化时，初喷存在一临界厚度；初喷破坏区主要集中在节理与洞周的相交处。

When the seeds sprout, some individuals produce annularly inflated hair zones above early initial roots near root tip meristematic zones.

The conclusions show that with γP0 increasing the nonlinear dispersion curves shift to the negative region of δ,the upper branch of the curve will form a ring when γP0 exceeds a critical value,while the anomalous dispersion region of group velocity dispersion induced by fiber Bragg grating vanishes,group velocity dispersion becomes only one normal dispersion region.

结果表明：随着βg2的增加，非线性色散曲线的上、下两支向δ的负值区移动，当超过某一临界值时，曲线上支开始形成环，这时光纤光栅引起的群速度色散中的反常色散区消失，全部变成正常色散。

(1) The input of the internal fixation implant should be in accordance with the compressive trabeculae and be clingy with the femoral calcar, Abduction in small degree (10-30°) will improve the stress in femoral neck region. The stress distribution of the femur under extemal violence explained why the old people are easy to get the middle and low part fractures of the femoral neck and intertrochanteric fractures.(2) The finite element model of femoral neck fracture is good in orrowing various fixation methods for femoral neck fracture.

(1)三维有限元方法用于研究不规则物体是一种有效、准确的数值方法，不仅能考虑到所研究物体的几何形状，而且也考虑到物体的内部结构特性；股骨颈处的压力骨小梁和股骨距是重要的承载结构，内固定物的放置应循压力骨小梁方向尽量紧贴股骨距钻入；载荷主要通过压力骨小梁和股骨距传导至股骨干的中下1/3处；一定角度的下肢外展（10-30°）会较明显的增加股骨颈区的应力，而下肢的内收反而会减小此区的应力；暴力作用时股骨上端应力分布特点从生物力学角度说明老年人易于发生股骨颈中下段骨折和转子间骨折的原因。

Compared with the FFT-based computation to CAF, the presented method can scan the target only in certain circular sector instead of the whole ambiguity plane, which may decrease the computational load.

与基于FFT计算互模糊函数的方法相比，采用这种方法的优点是在检测目标时可以只扫描某个环形扇区而不用计算整个模糊平面，减小了计算量；另外，由于在计算互模糊函数时极角和极径的取样间隔可以任意选择，突破了时域采样间隔的限制，可在时延和频移上均得到高精度估计。

Five pieces of paleogeographic maps were made out with modern stratigraphic principles and sedimantary system method. It is shown by the maps that in the beginning of the Changzhougou time the Yanshan Region was occupied by alluvial environment with paleoriver flowing northeast, in the middle of the Changzhougou time a transgression changed whole Yanshan Region into shoreline-shallow sea environment gradually, and sedimentary boundary extended so continuously that by the Gaoyuzhuang time it had overpassed far beyond the Yanshan Region.

在缺乏良好等时面的情况下，本文依据现代地层学原理和沉积体系分析法编制了常州沟组初期与中期，串岭沟组初期，大红峪组初期，及高于庄组初期燕山地区的岩相古地理图，示意了燕山地区在长城纪时由冲积扇-河流为主的陆地环境向滨海-浅海环境的演变过程，并揭示了沉积区域不断扩大的趋势，表明常州沟组初期，以蓟县-宽城为轴线发育了冲积相组，海岸线可能在燕山以北，常州沟组中期发生海侵，沉积区扩大至整个燕山地区，大红峪组时海盆范围继续扩大，高于庄组时，沉积边界已远远超出燕山地区。

Of the five stages deformation, the exact ages of the (2) and (3) were determined by 40Ar/39Ar method as 290 and 259 Ma respectively.2. New results on the metamorphic belts and associated metamorphism of the Xiaopu metamorphic rocksBased on detailed microtextural observations and occurrence of typical metamorphic minerals, five metamorphic belts in the Xiaopu metamorphic rocks are identified. From the north to the south, they are biotite belt, garnet belt, staurolite belt, andalusite belt, and sillimanite belt. I suggested that the metamorphic belts occurred in the Xiaopu area belongs to the high temperature/low pressure series, may have resulted from the later Permian crust extension at ca. 290 Ma.3. I suggest that there may have been a Carboniferous backarc basin along the southern slope of the Harlik Mountain.Detrital Zircon SHRIMP U-Pb dating indicated that the sedimentary age of the Julideneng formation lithic sandstone must be later than late Devonian, most likely is Carboniferous rather than previously thought Precambrian. Analyses on its geologic setting, location of provenance, and sedimentary environment suggest the Carboniferous strata may form in a lagged backarc basin bounded by backarc uplifts.5. Reconstruction of the post-Paleozoic tectonic evolution history of the Harlik MountainThe tectonic evolution of Harlik mountains since the Paleozoic were reconstructed as followings:(1) arc-affinity magmative activities occurred during the middle-Ordovician to early-Silurian;(2) the middle-Silurian to late-Devonian was a back-arc uplift stage;(3) back-arc extension featured the Carboniferous period;(4) post-collisional extension and/then compression during Permian;(5) at the Mesozoic, differential uplift developed; and (6) the late Cenozoic is the intra-continental re-orogen stage.6. Primary estimation of the crust shortening is madeThe folded pre-Mesozoic strata were used to estimate crust shortening along the Harliknanshankou-Koumenzi, Shichengzi-Baishitou, and Qincheng-Xiaopu sections. Their shortening ratios are 16.2%, 19.8%, and 20.1% respectively corresponding crust shortening are 4.3, 9, and 11.3 km.

The method comprises: when mobile station initiates a joint attach request or a route area/location area renewing request, if the MSC/VLR selected by the serving SGSN needs to be transferred to other MSC/VLR due to heavy load or reset, it returns a location renew acceptance message carrying virtual NRI to the serving SGSN; the according to the NRI carried in the location renew acceptance message, the serving SGSN decides if the MS needs to be transferred to other MSC/VLR; the serving SGSN reselects the serving MSC/VLR in node pool, and re-initiates a location renewing request to transfer the MS to other MSC/VLR.

当移动站发起联合附着或路由区/位置区更新请求时，若服务SGSN选择的MSC/VLR因负载过重或重启等原因需要将MS转移到其他MSC/VLR，则向服务SGSN返回携带虚拟NRI的位置更新接受消息；服务SGSN根据接收的位置更新接受消息中携带的虚拟NRI判断需要转移MS到其他MSC/VLR，服务SGSN在节点池中重新选择服务MSC/VLR，重新发起位置更新请求，将MS平滑地转移到其他MSC/VLR进行附着或位置区更新流程。
