Although 25 eyes presented with acute angle closure glaucoma, 6 eyes were insidious onset and asymptomatic. While 27 eyes relieved pupillary block after laser iridotomy or surgical peripheral iridectomy, 4 eyes required vitrectomy or laser photomydriasis to relieve pupillary block. Five eyes (16%) developed chronic angle closure glaucoma due to peripheral anterior synechia. one could be controlled by chronic medical therapy, three required trabeculectomy, the another one even required cyclocryotherapy because poor IOP control after trabeculectomy.

虽然大多数的病例（25只眼）以急性发作为临床表徵，但有6只眼为隐袭性，无任何临床症状。27只眼经雷射虹彩瞳孔术或外科周边虹彩切除术后可以解除瞳孔阻塞，另4只眼无法解除而需作玻璃体切除术或雷射光瞳孔放大术。5只眼(16%)因周边前黏连发生慢性隅角闭锁性青光眼，其中1只眼可以药物控制，3只眼需做小梁切除术，另1只眼做小梁切除术后眼压仍无法控制而接受睫状体冷冻治疗。

objective to evaluate early signs of avascular necrosis of femoral head in adult by ct and to guide clinical treatment.methods the cases with suspicious diagnose of anfh were scaned in the both hip joints by x ray and ct to find the early signs of anfh with ct.results early signs of anfh using ct showed that, in 38 femoral heads 31 cases, there were radiate star shape of high density osteosclerosis of the trabeculae in 13 femoral head.twenty five femoral heads showed osteosclerosis and trabeculae structure disappearing and vague,incoordinately low ostedensity area and cyst change.there were fracture under the cartilage and light subsid in 5 cases.the cases in stage ⅰwere given decompression, while the pationtsresul in stageⅱand stageⅲ were given decompression and ostetransplant.conclusion ct results show that the sign of the high osteodensity and low osteodensity and cyst change can disply early anfh.

摘 要］目的：探讨成人股骨头缺血性坏死的早期ct征象并指导临床治疗。方法：对临床疑诊anfh的全部病例均行x线平片及ct检查，分析anfh的早期ct征象。结果：早期anfh的ct表现：31例38个股骨头，其中13个股骨头骨小梁呈放射状高密度的"星状征"，骨小梁境界清楚、锐利，属ⅰ期；25个股骨头表现为骨硬化，骨小梁结构消失、模糊不清，骨密度减低及囊性改变，属ⅱ期；并有5个股骨头在ⅱ期影像学改变基础上出现软骨下骨折及轻微塌陷，属ⅲ期。治疗结果：ⅰ期行钻孔髓内减压术，ⅱ、ⅲ期行钻孔减压植骨术。

At this time, loosen the connection screw of standard section with spanner, hang the shaft of hand crane on the upper angle bar, sway the shaft of hand crane upward, separate this standard section from the next section, and lay it in the suspension coop, dismantle the other standard section for the same method, and turn the shaft to another direction, draw the lifting wire rope tightly, the operation staff leave the suspension coop, open the lock stopping instrument, fall the suspension coop to next position and lock the brake instrument, the operation staff return to the top of suspension coop, continually dismantle note: forbid the staff leave on the top of suspension coop or in the coop when the suspension coop is running

8.1折除时，首先将吊笼用停层装置停靠在待拆除的标准节的下两节上，操作人员上到吊笼顶，卷扬机松绳，用小吊杆将顶梁略向上提起，拔出顶梁横销，使顶梁值得徐徐降下，降到拆除节下一节中间框架角处，并重新穿上横销，这时用板手将标准节连接螺栓松开，将手摇起重机小吊杆钩挂在待拆节上框架用钢土，到吊笼内，用同样的方法拆下另一节标准节，然后将吊杆转向不影响升降机运行的方向，收紧起升钢丝绳，操作人员离开吊笼，打开锁止机构，使吊笼下降到下一个拆除位置，并将锁止机构锁死，人员重返笼顶，进行下一拆除循环注意：在吊笼运行时绝不允许有人员留在吊笼顶部或吊笼内

When dismantle the machine, firstly, stop the suspension coop on the lower 2 sections of the standard sections, the operation staff go on the suspension coop top, the hoisting machine loosen rope, lift the pillar with small shaft, pull out the horizontal pin of pillar, let the pillar fall slowly to thedismantled section's middle angle bar, insert the horizontal pin again. At this time, loosen the connection screw of standard section with spanner, hang the shaft of hand crane on the upper angle bar, sway the shaft of hand crane upward, separate this standard section from the next section, and lay itin the suspension coop, dismantle the other standard section for the same method, and turn the shaft to another direction, draw the lifting wire rope tightly, the operation staff leave the suspension coop, open the lock stopping instrument, fall the suspension coop to next position and lock the brakeinstrument, the operation staff return to the top of suspension coop, continually dismantle note: forbid the staff leave on the top of suspension coop or in the coop when the suspension coop is running

The design realm in the province of Jilin, use more software is the bridge Doctor system, bridge master, system of ASBEST, procedure of QJX and province highway of Jilins survey to design the hospital to by oneself develop of the T beam plank beam painting procedure, the cover beam calculation painting procedure, a pillar calculation procedure, the upper part procedure compute a procedure mostly, even some procedures can paint, but the province painting of basic and dissatisfied foot Jilin of born diagram paper style, the diagram paper the modification quantity compare greatly, the procedure that the lower part procedure adopts to by oneself

在吉林省内设计领域，使用较多的软件是桥梁博士系统、桥梁大师、ASBEST系统、QJX程序及吉林省公路勘测设计院自行研发的T梁板梁绘图程序，盖梁计算绘图程序，桩柱计算程序，上部程序多是计算型程序，即使有些程序能够绘图，但生成图纸基本不满足吉林省绘图风格，图纸修改量较大，下部程序多采用自行编制的程序，但大多数程序是DOS系统的程序，使用不方便，同时与现行规范多有不符。

In an attempt to evaluate the safety and efficacy of Healon in trabeculectomy, 20 eyes with Healon and 20 eyes without Healon injection after trabeculectomy are compared. Trabeculectomy using Healon will not induce transient rise of intraocular pressure. By filling the anterior chamber with Healon, a tamponing effect results which will maintain a deep chamber and reduce complications such as flat anterior chamber, choroidal detachment and striate keratopathy in the early postoperative period. In long-term evaluation there is no difference in pressure control, conjunctival scarring and corneal endothelial cell loss between Healon group and Non-Healon group.关键词 trabeculectomy , flat anterior chamber , choroidal detachment , intraocular pressure

为了评估Healen在小梁切除术中之疗效及安全性，选20位接受小梁切除术者，同时注射Healon於前房为实验对象，另20位接受传统小梁切除术为对照组，发现使用Healon并不会引起一过性眼压上升的现象，Healon注入前房，产生填塞作用，最大的好处是可以维持前房深度，减少术后合并症如前房消失，脉络膜剥离及角膜水肿等，然长期追踪，对於降眼压的幅度，不因使用Healon而可达到低眼压状态，也不会减少结合膜瘢痕化而促进房水引流，然Healon系一无毒，无炎性，无抗原性高黏稠性的物质，不因使用而发生炎性反应，同时有保护角膜内层细胞的功能。

But the steel box girder is typical space thin-walled bars, because of bending-torsion coupling and steel curved box bridge distribution of stress is relatively more complicated even under dead load, so it is necessary to distribute emulation analysis to the real stress of curved box bridge.

但是钢箱梁是典型的空间薄壁杆件，由于弯一扭耦合作用，曲线钢箱梁即使在恒载作用下其应力的分布也比较复杂，因此有必要对曲线钢箱梁实际的应力分布进行仿真分析。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
