Several coterminous bands could be observed by PAGE of natural Eisenin Ⅰ and several coterminous peaks of Eisenin Ⅰ were also detected with MALDI-TOF-MS when the molecular weight of three main peaks are 24, 645, 25, 052 and 25, 281, separately. The amino acid composition of Eisenin Ⅰ(pI. 8) is specilized with high content of acidic amino acids and low content of alkaline amino acids; At the same time, the content of Ser and Thr are quite high and that of Lys, Met, Phe and Trp are quite low. Eisenin Ⅰ is highly homologous with serine proteases. Then, by fibrin plate assay, Eisenin Ⅰ was identified to be a plasmin and also a plasminogen activator, and the fibrinolytic activity was inhibited by PMSF (an inhibitor of serine proteases).

But the EGTA treatment had the opposite effect.(3)During chilling stress,Ca~(2+)treatment could delay the decrease of K~+,Mg~(2+), soluable protein content and the increase of Ca~(2+)content;And it could enhance the increase of soluable sugar,free amino acid,proline,heat stable protein and Na~+ content of the heat-shock-induced cucmber seedings.Then it enhanced the osmoregulation ability and delayed the decrease of water potential of the heat-shock-induced cucmber seedings.But the EGTA treatment had the opposite effect.

3钙处理能减缓冷胁迫下热激黄瓜幼苗的可溶性蛋白质、K~+、Mg~(2+)含量的下降以及Ca~(2+)含量的上升，增强可溶性糖、游离氨基酸、脯氨酸、热稳定蛋白和Na~+含量的上升，增强了热激黄瓜幼苗的渗透调节能力，从而缓解了低温下水势的下降；而EGTA处理则相反。

就一铅锌冶炼厂周边蔬菜对重金属的吸收与富集进行了研究，结果表明：所有被检测蔬菜中Pb和Cd含量严重超标；根类、葱类和叶菜类蔬菜中Zn含量有所超标，其它种类蔬菜一般未超标；蔬菜中的Cu含量未超标。

For the composites with a low content of TiC particle, the rupture manner was mainly the nucleation of cavity and following ductility splitting fracture. But for the composites with a high content of TiC particle, the cracking and decohesion of TiC particles were the main rupture mechanism. For the composite containing a middle TiC content, the rupture mechanism consisted of the above two styles, but the former was the dominating mechanism and the later was the subordinate mechanism.

对TiC体积分数较低的钢基复合材料，拉伸过程中TiC颗粒界面上的孔洞形核及随后塑性撕开机制是其断裂失效的主要机制；对TiC体积分数较高的钢基复合材料，拉伸过程中TiC颗粒的开裂及脱落是其断裂失效的主要机制：对TiC体积分数介于上述两者之间的钢基复合材料，拉伸过程中TiC颗粒界面上的孔洞形核及随后塑性撕开机制在其断裂失效过程中占主要地位，而TiC颗粒的开裂及脱落占次要地位。

In the same depth, the content of total nitrogen of broad-leaved deciduous forest in 0~10 cm depth is maximum ,and the average total nitrogen of the bamboo forest is maximum in 10~20 cm and 20~30 cm. The available phosphorus content of broad-leaved deciduous forest is minimum, and the available phosphorus content of coniferous forest is minimum, the deviancy is very big, which is mainly related to the human being's activities and the way of soil usage.

同一土层深度，落叶阔叶林在0~10cm土层全氮含量最高，而毛竹林在10~20cm和20~30cm土层全氮含量都超过落叶阔叶林，使得毛竹林在土壤平均全氮含量为最高；各种森林类型中以阔叶林尤其是落叶阔叶林的速效磷含量最高，而针叶林的速效磷含量最低，空间变动性很大，这主要和人类活动及土壤的利用方式有关。

The spectral reflectance of dichondra turf was studies by measuring the leaf relative water content, chlorophyll content and soil water content under different drought levels.

通过在不同灌水处理下马蹄金草坪干旱胁迫试验，对草坪反射光谱的变化及所对应的叶片相对含水量、叶绿素含量以及草坪外观变化进行测定。

The results showed that N content increases the sp^3 C-N content and decreases content and decreases the sp^2 C-N. The refractive index and electronic polarization of dielectric constant decreases with increasing N/C ratio.

研究结果表明，随着CN薄膜N/C比的增大，sp^3 C-N的形成受到抑制，sp^2 C-N的形成增多，薄膜折射率以及介电常数电子极化贡献部分降低。

Triglyceride content in the fat body was as high as 75% at the initial stage of pupation, but decreased gradually with the development of the pupae. Accordingly, triglyceride content in the ovary was only 20% at the beginning and increased to 64% before eclosion, and the content of diglyceride and free fatty acids in the blood also increased significantly. This suggests that fat in the ovary is transported from the fat body through the blood.

在化蛹初期，脂肪体中甘油三脂的含量高达75％左右，随着蛹体发育而逐渐降低；与此同时，卵巢中甘油三脂的含量在化蛹初期仅为20％，到羽化前增加到64％；血液中甘油二脂和游离脂肪酸的含量也有明显增加，说明卵巢中的脂肪是由脂肪体经血液转送而来的。

However, keywords can only represent the simple content, which easily dissever the relevancy of the content The deep-content representation and application are not developed, so semantic navigation is not satisfied at present. Time mechanism is a kind of navigation mechanisms that uses time for the signpost, and determines navigation route according to the time of occurrence.

时序机制指以时间为导航路标、根据事物发生的时间顺序确定访问路径的一种导航机制，主要应用于WWW信息空间中以时问顺序为线索组织信息的结构中；空间机制指依据对象间的空间关联，为用户指引路径，提供导航路标的机制，应用于具有空间特征的结构中；社会机制指利用先行者的经验、建议为后来者指引路径的行为，原来主要应用在推荐系统、协作系统中，目前已经在主流的信息检索系统中得到了应用，如在CNKl知识网络服务平台（CNS 5.0）中的应用。
