The apriori and aposteriori H〓-optimal filtering question can be solved directly. L〓 Apriori and aposteriori filtering with an H〓 error bound can be solved by semidefinite programming. Robust H〓 apriori filtering and robust apriori L〓 filtering in discrete-time system are subject to a nonconvex constraint.

对这些滤波问题解法的改进同连续系统下的情况基本类似，对确定性系统的H〓验前滤波和验后滤波，本文解法可直接得出最优滤波问题的解；对H〓约束下的L〓验前滤波及验后滤波，其解可归结为一凸优化问题；但不确定性系统H〓验前滤波和鲁棒L〓验前滤波的LMI解法中有了非凸约束，因此要用迭代法求解。

After 10 days, 20 days and 30 days for grass carp (Ctenpharyngoden idellus Cuvier et Valencinnes) immunized by being injected Aeromonas hydrophilia, the ANAE (acid α-naphthyl acetate esterase) positive cells ratioes increased, and the same time it was found that the ACP activity increased up too, it showed that the fish bodies were being at immune responding situation and their immnue activities enhanced.

通过对草鱼免疫器官的六种同工酶的分析发现：LDH在血浆、血液细胞、脾脏和胸腺中都表达为5条区带，前肾还额外显示出X酶带，血浆只有3条酶带；ADH除了胸腺为一条带以外，其它的均为3条酶带；MDH和3-GPDH在这些组织中均表达为3条酶带；EST在前肾中为7条酶带，其余的都为6条酶带；POX只在前肾和脾脏中表达为2条酶带。

Based on the concept of zero-path tracking in homotopy which is generalized into minimum of energy function path tracking and considering that different homotopy path has greater impacts on convergence speed, a new method is put forward——the non-line homotopic BP algorithm.

According to the relationship of Yanshan epoch granites and NE ductile shear zones of main structure of this region, and regional isotope chronology data, the granitoids of this region are divided:(1) pretectonic, qnartze monzonite -granites assemblage, representative plutons: Shigujian, Erwan, Egongbao, and Yunfengding;(2) syntectonic granite assemblage, representative plutons: Tiantangzhai, and Jiuzihe;(3) posttectonic granite assemblage, representative plutons: Daguping and Bijiashan. These assemblages differ from precollision , syncollision and postcollision intrusive assemblages.

When the parameter matching of the wheel location is improper, namely, the matching between the wheel toe-in and the wheel camber angle is ill-suited, abrasion of the two wheels of the same steering axle is inside or outside simultaneously, because of wheels sideslip. However, when double-front-axle steering system failure take place, abrasion of the two wheels of the same steering axle is in the same side, and that, tyre abrasion direction of front and back steering axles is rightabout. That is to say, if tyre abrasion of front steering axle lie in the left side, tyre abrasion of back steering axle lie in the right side to a certainty, which is the rule of tyre abrasion of double-front-axle steering automobile.

当定位参数匹配不当时，同一转向轴上左右车轮的磨损部位都在内侧或外侧，原因是左右车轮在滚动的同时还要产生相向或反向侧滑；而双前轴转向汽车前、后转向轴引导汽车转向方向不一致时，同一转向轴左、右车轮的磨损部位都在同一侧，而且前、后转向轴上的车轮偏磨损方向正好相反，即如果前转向轴左、右车轮磨损部位在左侧或右侧，那么后转向轴左、右车轮磨损部位就在右侧或左侧，这是双前轴转向汽车特有的轮胎磨损规律。

Results The anterior bundle of ulnar collateral ligament originates from the inferior aspect of the medial epicondyle and inserts immediately adjacent to the joint surface on the ulna near the sublimis tubercle. The posterior bundle originates from the medial epicondyle slightly posterior to its most inferior portion and inserts broadly on the olecranon process. The lateral collateral ligament arises from the inferior aspect of the lateral epicondyle. Two types of conjoined lateral collateral and annular ligamentous insertions on the ulna were observed. Type Ⅰ(61.2％) was bilobate and type Ⅱ(38.8％) was a single broad conjoined type with insertion on the ulna. The anterior band of anterior bundle was more tighten than the posterior band as the elbow flexed less than 60°. When the elbow flexed over 60°, the two parts of anterior bundle were equally tightened. The posterior bundle was tightened as the elbow was flexed more than 90°. The lateral collateral ligament was tightened gradually as the elbow moved in flexion.

Wire electrode based on the trajectory of the different forms of control, WEDM can be divided into three types: one is shaped by the imitation controlled cutting in line in advance and work to create the same shape by mold, when processing the workpiece at the same time rough and on the mold clamping in the machine tool table, in the process of cutting wire electrode tightly against the mold on the edge of the track for the mobile, thus cutting out and die on the same shape and precision to the workpiece; another One is the electro-optical tracking control, to carry out the cutting line, before the basis of certain parts to enlarge the proportion of drawings depicts an electro-optical tracking map-processing machines will be placed in design stage of electro-optical tracking, tracking platform Photoelectric first line of graphics has always been to follow the track of the Mexican campaign, and then through the use of electrical, mechanical linkage to control the machine tool table, together with the workpiece so相似形wire electrode relative movement, thus cutting out the same shape and design to the workpiece; again a digital control, the use of advanced automatic control of digital technology-driven machine tool in accordance with the pre-processing parameters according to the workpiece geometry pre-processing procedures for the preparation of a good CNC auto-complete processing, the production does not require appearance on board the need to map to enlarge map of the previous two form of control has a higher machining accuracy and a broad range of applications, both at home and abroad more than 95% have adopted WEDM NC.

根据对电极丝运动轨迹的控制形式不同，电火花线切割机床又可分为三种：一种是靠模仿形控制，其在进行线切割加工前，预先制造出与工件形状相同的靠模，加工时把工件毛坯和靠模同时装夹在机床工作台上，在切割过程中电极丝紧紧地贴着靠模边缘作轨迹移动，从而切割出与靠模形状和精度相同的工件来；另一种是光电跟踪控制，其在进行线切割加工前，先根据零件图样按一定放大比例描绘出一张光电跟踪图，加工时将图样置于机床的光电跟踪台上，跟踪台上的光电头始终追随墨线图形的轨迹运动，再借助于电气、机械的联动，控制机床工作台连同工件相对电极丝做相似形的运动，从而切割出与图样形状相同的工件来；再一种是数字程序控制，采用先进的数字化自动控制技术，驱动机床按照加工前根据工件几何形状参数预先编制好的数控加工程序自动完成加工，不需要制作靠模样板也无需绘制放大图，比前面两种控制形式具有更高的加工精度和广阔的应用范围，目前国内外95%以上的电火花线切割机床都已采用数控化。切割属电加工范畴，是由前苏联人发明的，我国是第一个用于工业生产的国家，当时由复但大学和苏州长风机械厂合作生产的这是最早的机型叫复旦型，我们国内在此基础上发展了快走丝系统。欧美和日本发展了慢走系统LS
