The main factors affecting the soil-structure interface behaviors were found experimentally and theoretically, including: 1 the thickness of the interface that is five to six times the average grain size of the soil; 2 the aeolotropy of interface, which is responsible for anisotropic response of the stress-strain response of the interface; 3 two physical states, including crashing and compression of the soil near the structure surface, which govern the stress-strain response of the interface strongly; 4 two shear deformation components due to sliding and constraint of the structure surface relative to the soil respectively, which forms the deformation of the interface; 5 the volumetric strain due to dilatancy, which is found to be composed of a reversible dilatancy component and an irreversible dilatancy component. 4. A unified constitutive model of the interface, based on new elasto-plasticity damage theory, was developed. It was confirmed to be effective for the conditions considering monotonic and cyclic shearing, coupling effect of shear and volumetric strains, evolution of physical state, micro-structure aeolotropy of the soil and the resulting aeolotropy of the interface as well as the three normal boundary conditions stated above. 5. 2D and 3D finite element formulations of the present model were derived and incorporated into the FEM codes. They were applied to the evaluation of practical engineering problems with different typical interfaces between soil and structure. The new model was shown to be reasonable and effective.

We coupled the IgG of monoclonal antibody N34 specific to UK and the Fab of monoclonal antibody SZ-51 specific to the membrane protein GMP-140 of activated platelet. The bispecific antibody (N34 SZ-51) is able to bind UK and plasma-clot simutaneously. It enhanced plasma clot lysis 5 fold by HUK whereas it enhanced plasma clot lysis 38 times by LUK. UK in association with the bispecific antibody didn't decrease the concentration of fibrinogen in the assay supernatants.

The results indicate seawater concentration has no effect on absorbency, pH, relative density, dry matter and water contents in Aloe vera leaves. While, seawater stress causes increased MDA and membrane penetration, decreased phytochroms, prolines and NO_3~--N. It is beneficial to plant growth when irrigation was done with 10% seawater, because of higher ratio of K~+/Na~+ and lower ratio of Na~+/Ca~(2+). In addition, the polysaccharide contents in Aloe vera leaves increase twice and triplication under 25% and 50% seawater irrigation respectively, the barbaloin contents increase over triplication in var. 75% seawater and over twice in var. 50% seawater and var. 100% seawater. However, when seawater concentration exceeds 25% the growth of plant was inhibited, biomass decreased, flowering time was deferred, Ca~(2+) content decreased caused by Na~+ accumulation in leaves.
结果表明:在海水胁迫下,库拉索芦荟全叶汁的吸光度、酸度、相对密度、总固形物和水分含量总体上受海水浓度的影响不大;但芦荟叶的丙二醛含量和质膜透性增加,叶绿体色素、脯氨酸和硝态氮含量减少;在10%海水浇灌下,芦荟叶细胞具有较高的K~+/Na~+比和较低的Na~+/Ca~(2+)比,对库拉索芦荟的生长有一定的促进作用;在25%海水和50%海水浇灌下,芦荟多糖含量提高了2-3倍;在75%海水浇灌下芦荟甙含量增加了3倍多,在50%海水和100%海水灌溉下,其含量也增加了2倍多;当海水浇灌浓度超过25%后,库拉索芦荟的生长明显受到抑制,生物量降低,抽苔期推迟,同时,海水浓度的增加也导致芦荟叶中累积大量Na~+,从而使得芦荟叶中Ca~(2+)含量降低,但Mg~(2+)并没有受到海水浓度的影响;用浓度低于75%的海水浇灌库拉索芦荟可以降低剖面深度在0-100cm之间的土壤盐度;其抗氧化保护酶中超氧化歧化酶的酶活力相对保持稳定,过氧化物酶的酶活力在10%海水浇灌下明显提高,随后则下降,而过氧化氢酶的酶活力则随海水浓度的升高而下降。

The call developmental process of Psittacula agapornis consists of five instinct phases according to its call character. In the first phase (congenital cal1 phase, CCP, 0~12 day of age), the juveniles only produce single syllable with short syllable length. The second phase(blank-model-forming phase,BMFP, 13~30 day of age) is important for formation of vocal learning pathways. During this phase, the calls characterized by more and longer syllables. In the third phase (call-model-forming phase,CMFP, 31~45 day of age), the call development is guided by a model system for vocal learning, vocal learning is engendered so that some calls with multi-syllables with UP1 are produced, principal frequency has increased about by 920 cent, the number of note is double that of second phase. The short-term memories are transformed into long-term memories in the forth phase (call-feedback-learning phase,CFLP, 46~90 day of age). The call of juveniles is a close match to tutor call which accompanied by double various sounds with BS and UP1, and more resonance components were formed. Second principal frequency has increased about by 970 cent, the number of note increases by 2.6~3.0 times. During the fifth phase (excellent call phase,ECP, after 91 d), vocal motor pathway is developed and the calls are accompanied with most stable, harmonious vari-tone and complex repertoire.

Polymorphism of HLA-DQB1 promoter region in Hans IDDM patients and normal controls have been identified by PCR, PCR/SSCP and PCR/sequencing methods.No differences were found in y and s box between patients and controls carrying different allele as well as in different ethnic groups. There are two different sequences in x box,but CCTAGAGACAGATT sequence locates frequently on the haplotype with DQB1.0302 allele. Polymorphism between transcription point and y box (at position -44~-46 and -59~-61) might be associated with the genetic susceptibility to IDDM. Additionally,a new single base mutant (CACC→CAC A ) was found at position -131 and -128 in two patients carrying DQB1.0601 allele.
