The spermatozoa are embeded in a extracellalar matrix composed of high dense fibrils matrix and flocculent and concentric vesicles similar to that in the primary spermatophore layer, but the later lack of spermotozoa. The flocculent and concentric vesicles are often seen to release their contents around the main body of spermatozoa. The spermatozoa may absorb the contents to form vesicular zone and membrane zone in sperm nucleu. The secondary spermatophore layer is distinctly subdivided into inner region and outer region. The loose outer region consists of canaliculated reticulum and large flocculent vesicles.

输精管内的精荚为管状，由精子群、精荚基质及初级精荚壁和次级精荚壁组成，初级精荚壁与精荚基质是相连续的，它们之间无明显界限，两者均由电子密度较高的纤丝状基质和絮状泡和同心圆泡组成，但后者不含精子，后者中的絮状泡和同心圆泡常在精子主体部周围释放内含物，可能与形成精子细胞核中的泡状带和膜状带有关，在交配后的雌虾，其头胸部腹面上粘着的精荚中，其基质内已不见絮状和同心圆泡，仅见稀疏的纤丝。

Result:After removal of the bilateral lower molars, the remodeling and degenerative activities in different layers of the condyles increased, such as vesiculation of endoplasmic reticulum, distortion of mitochondria and increase of lysosome. Furthermore, the sequential arrangement of collagen fibrils was disturbed, the collagen network broke down and the proteoglycan granules decreased.

Grew on the normal temperature, it was shown that the deposits of calcium antimonate being the indicator for Ca(superscript 2+) localization mainly concentrated within the vacuoles and intercellular spaces and there was also some Ca(superscript 2+) deposits in cell walls. But when Garyota urens L. was treated by the temperature of 2℃ for 48 h, the level of Ca(superscript 2+) increased in cytoplasm and plasma membrane, but decreased in vacuoles and intercellular spaces considerably. At the same time, the ultrastructure of chloroplasts suffered from chilling: the membrane of chloroplasts had been damaged, the layer of thylakoids was exiguous and unclear, the photosynthetic rate decreased evidently. And when Garyota urens L. was treated by the temperature of 2℃ for 120 h, the deposits of Ca(superscript 2+) mainly concentrated within the cytoplasm, nucleus and plasma membrane and there was also some Ca(superscript 2+) deposits in vacuoles, and the ultrastructure of some cells was simultaneously damaged severely: Chloroplasts structure, vacuole membrane and nuclear membrane had been damaged fully, the structure within the cell had become unclear, and the cell only have respiration.

研究结果表明，未经低温处理的董棕幼苗叶肉细胞，焦锑酸钙沉淀颗粒大量出现在液泡和细胞间隙中，细胞壁中也可见少量沉淀，而细胞基质中则看不到焦锑酸钙沉淀；经2℃ 48 h低温处理后，细胞基质和细胞膜上焦锑酸钙沉淀增加，而液泡和细胞间隙中的焦锑酸钙沉淀则显著减少，并且超微结构已初步显示出寒害的特徵，叶绿体外膜部分破损，类囊体片层稀疏且排列不规则，光合速率明显下降等；经2℃ 120 h低温处理后，细胞间隙内的焦锑酸钙沉淀极少，有的也紧贴在细胞外壁上，而细胞基质和细胞膜上则分布有非常多的焦锑酸钙沉淀，在核基质和液泡中也可见到少量的焦锑酸钙沉淀，并且超微结构遭到了显著破坏，叶绿体结构完全被破坏，核膜与液泡膜严重破损，内部结构模糊，细胞只表现为呼吸作用，不进行光合作用。

Since 1962, when Gross and Lapiere discovered the first MMPs-collagenase, man had discovered various of MMPs in succession, where MMP-2 has a strong degradational effect on extracellular matrix, it is secreted bymacrophage, smooth muscle cells and endothelial cells and so on.

Three types of base asphalt and six SBS were used to produce SBS modified asphalt. The interaction of SBS modified asphalt was discussed in different states between the base asphalt and SBS based on their compositions. Through the traditional tests, such as penetration, soften point and ductility, and US SHRP tests, the results indicated that influences to affect the temperature susceptibility, high and low temperature performance, aging characteristics are base asphalt, SBS types and their dosages. The functions of penetration to viscosity and complex shear modulus G~* to complex dynamic shear viscosity η~* were set up, and then theviscosity-temperature susceptibility of wide temperature span and the calculation method of low temperature viscosity were obtained."Process" evaluation criterions, high grading critical temperature T_ and low grading criticaltemperature T_ , were suggested according to the high and low temperatureperformances of SBS modified asphalt. Using the experience of Repeated Creep and Recovery Test for Binders, a new high-temperature evaluation index,modification rutting factor G~*~(-9) was obtained. The results after RTFO and PAV aging indicated that traditional tests didnt differentiate base asphalt and SBS modified asphalt, but dynamic mechanics temperature spectrum and G*-5 black chart clearly reflected the influence of aging to the SBS modified asphalt. With the IR and GPC tests, the reason of aging to the SBS modified asphalt were due to asphalt phase oxygenated and SBS phase depredated.

Sol–gel/diaminobenzoic acid hybrid materials were also generated to be used as the MALDI matrices for the analysis of oligonucleotides. It is because that DABAs have good molar absorptivity at wavelength of 337 nm. Furthermore, two amino functional groups attached to the aromatic ring in DABAs can also suppress the cation adductions of oligonucleotides and leave the protons to the oligonucleotides during MALDI-MS analysis. This matrix system can be used as an alternative for the analysis of oligonucleotides.

本论文也利用双胺基苯甲酸与溶胶凝胶混成产物当做MALDI基质来分析DNA分子，利用双胺基苯甲酸本身具有吸收雷射的特性，且其含胺之官能基可和钠、钾离子竞争DNA上磷酸根的负离子结合部位，因此可和DNA有较强的亲合力，而在脱附游离的过程中并可转移质子给磷酸根，可有效降低盐类的干扰，此一基质系统可取代传统MALDI基质混合胺盐的效果，适合用於DNA样品的分析。

The results showed that two of the ball cactuses tested could growth well in solution culture , in which the growth rate was significantly higher than or equal to that in peatmoss culture. Among the four solution culture formulae , formula 4 had the highest biomass increment and uptake of N , P and Kfor Ferocactu horridus. The biomass of Echinopsis calochlora did not differ significantly among the four formulae , but significantly increased higher than medium culture. This study indicated that ball cactuses could grow well in nutrient solution culture.

Results indicated that pesticides show different variability in certain extent in relative response between different matrixes. Certain pesticides are matrix-dependent such as chlorothalonil, paraoxon, deltamethrin, methamidophos, acephate etc, among them, chlorothalonil have better relative response in acidic matrixes (as orange, tomato, grape, kiwi fruit) but have serious suppression in scallion, onion, garlic, leek, lotus root etc.

结果表明，各农药相对响应值具有不同程度差异，个别农药显示了较强的基质依赖特点(如百菌清、对氧磷、溴氰菊酯、甲胺磷、乙酰甲胺磷)；其中百菌清在酸性基质橙子、番茄、葡萄、猕猴桃、蘑菇中稳定，其基质对百菌清起到了保护性作用，且能够抑制或减少溴氰异构体2向异构体1的转化；而在大葱、洋葱、蒜、藕、梨等基质中存在显著的降解或抑制作用。

结果表明：在中性水环境中，贝体能积极地从外界水环境中吸收钙，并能旺盛地合成和分泌贝壳珍珠层及珍珠有机基质前体物质；持续的酸性水环境导致贝体的钙严重丢失，并引起珍珠质分泌细胞对有机基质前体物质的合成和分泌能力减弱；持续的碱性水环境虽能导致贝体对钙的积累，但珍珠质分泌细胞合成和分泌珍珠质有机基质前体物质的能力减弱；水环境的酸性或碱性程度越高，对珍珠质分泌细胞的合成和分泌活动的影响越大。
