By applying the specific properties and the fabricating technology of the deep etched elements presented by us, the even device of deep etched binary optics has been designed and fabricated which can be used in quasi-molecule laser exposure system. This even device is light in weight, easy to adjust and has a high utilization rate of energy and is able to project well-distributed light beams. So it is better than the conventional one which was an array made up of quartz sticks. The properties and designed parameters were studied and simulated. The fabricated even was precisely tested by high precision Alpha-Steper. The testing result of the surface relief structures of the even has been profoundly analyzed by introducing “boundary errors”. The theory agrees well with the results of the experiment. This is the first successful application of the deep etched theory and technology of binary optics to the exposure system of microfabrication.

Objective To investigate the effects of thoracic epidural analgesia on postoperat ive hypertension in patients with PD ***48cases of PDA were randomly divided into NTEA group(n =22)and TEAgroup(n =26).General anesthesia was used for NTE Agroup,and intramuscular injection of peth idine 1mg /kg was used when postopera tive pain occurs;general anesthesia combined with thoracic epidural anesthesia were used for TEAgroup,a nd thoracic epidural analgesia was u sed for postoperative ***,HR,RR,SpO 2 ,EKG were monitored during and after operatio n,angiotenic was used when the BP ele vated more than 20%compared with before *** Analgesia effect on TEA group was better than that of NTEA group(P <0.05),also postoperative BP was signific antly higher than that of before operation in NTEA group(P <0.01),and 18cases need nitroglycerin or s odium nitroprusside therapy;there was no significantly in-crease of BP in TEA group,only 2cases need nitroglycerin *** TEA had an excellent effect of postop erative pain-relief and blocked sympathetic nerve in patien ts with PDA,so it could reduce postoperative hypertension effectively.

Moment tensor solution, rupture process and rupture characteristics of the great Wenchuan M8.0 earthquake are studied by using 39 long-period P and SH waveforms with evenly azimuth coverage of stations. Our results reveal that the Wenchuan M8.0 event consisted of 5 sub-events of Mw≥7.3 occurring succesively in time and space. Rupture started with a Mw7.3 introductory strike-slip faulting in the first 12 s, then within 12?40 s, two sub-events with Mw7.6 and Mw7.4 occurred within 80 km northeast from the initial point with the dominant rupture type of thrust moving. From 40 to 62 s, a Mw7.5 and Mw7.4 right-lateral strike-slip type of sub-events occurred on the two sides of Beichuan, 120 km away northeast from the initial point. The whole rupture process lasted 105 s and unilaterally propagated from the initial point on the WS section of the Yingxiu-Beichuan fault to the NE direction, resulting in a 230-km-long surface rupture zone and the average surface dislocation is up to 4 m. Two asperities are identified and the whole rupture process is formed by WS and NE parts. In the WS part named Dujiangyang-Wenchuan, where the initial point is located, the rupture process showed reverse faulting with the maximum slip of 8.2 m. Around Mianzhu, rupture changed to right-lateral strike slip faulting and formed a Beichuan-Qingchuan large slip area. The rupture area on this part is about 10 km in depth, shallower than on the WS part. The maximum slip is 6.53 m. Consequently, there formed 2 segments with the surface dislocation larger than 6 m. One is the Dujiangyan-Wenchuan segment with the maximum surface displacement of 6.44 m, the other is the Beichuan-Qingchuan segment with the maximum surface displacement of 6.53 m. This segmentation may have its geological and tectonic background.

An O2-type layered LiNi 0.5 Mn 0.5 O2 was prepared by rapidly-quenched method, and the structural feature was studied by X-Ray Diffraction. The material synthesized at 950℃ was with a single O2-type structure. Charge and discharge in a voltage range of 2.0-4.35V, the discharge specific capacity of material at the 1st cycle is 143.1 mAh/g in a current density of 0.5 mA/cm2, and the plot of discharge was with two voltage plat at 3.6 V and 2.8V.

Large sample sampling was adopted in this paper for the statistical analysis of leaves of four populations of Vetiveria zizanioides （ introduced, local wild, domesticated wild populations of different years）. The results showed that four populations varied in different degrees in terms of tiller height, leaf biomass, and leaf biomass ratio. Leaf length, leaf width, and ratio of leaf width to length of different populations also varied, but had similar power-function change regularity, and showed converging leaf biomass growth pattern and leaf growth process.
