To evaluate the bioactivity of the glass-ceramics,the specimens were soaked in the simulated body fluid. The results indicate that fluorapatite shows needle-like microstructure, which is similar to that in human bone and teeth. The formation of needle-like fluorapatite is related to the heat treatment procedure, which results in needle-like fluorapatite crystals by accelerating one-dimension growth along the c-axis through the screw dislocation growth mechanism. The mechanical properties of the glass-ceramics are close to those of the human bone and teeth. The bioactivity test results show that apatite layer is precipitated on the materials surface after 3 d immersion in SBF, which indicates the glass-ceramics have a good bioactivity.

研究结果表明：氟磷灰石相呈针状，与人体骨和牙齿的磷灰石形貌相似，有利于提高材料的生物活性和生物相容性；氟磷灰石的形成是材料被迅速加热至高温进行热处理，使磷灰石以螺旋位错生长机制沿c轴晶化长大所致；经热处理获得的材料具有优良的力学性能，基本满足骨科和齿科用生物材料的性能要求；材料在体外模拟体液中浸泡3 d后，样品表面已有磷灰石层生成，表明该材料具有较高的生物活性。

This article mainly explains the safety principium of infectant factors in waste water vented by the paper making industry in China. Through the study on the experiment in open country and indoors with soil pole, indicating that it is a complicated process of biochemical degradation to form a layer, which has a biochemical capability to process COD degradation in polluted water from paper making industry.

综述我国造纸业污水中的污染因子危及地下水水质安全的机理，通过对野外试验和室内土柱试验的过程及结果进行分析研究，表明在包气带中形成一个以生物化学作用为主的生化层在造纸污水中COD降解是一个复杂的生物化学降解过程；生化层在天然状态下形成，由生物氧化带和生物氧化还原带形成，其形成过程具有明显的阶段性；只有当生物氧化还原带形成后，生化层才发育成熟，具备对COD降解的生化能力；生化层空间分布，仅局限在污水池、渠底部包气带中有垂向渗流的部分。

While the keratinocytes adhered well on the surface of silicone membrane with pseudopodia formation after 1 week under scanning electron microscope, and the cells kept normal morphological and proliferative properties 2 weeks later.

种植于生物硅膜上的表皮细胞，1周时扫描电镜下见表皮细胞在生物硅膜表面贴附较好，有伪足形成，提示细胞生长良好；2周时光镜下见生物硅膜上的表皮细胞形态仍正常，增殖良好。

In China, crop strews and energy crops are the main resource of bioenergy under the condition of secure food safe. There are lots of resource of crop strew, and only the main tree food crop can produce about 0.5 billion ton strew, which can maintain soil carbon and was used as the resource of bioenergy. In addition, there are about 0.1 billion hm2 waste hills and and that is suitable for farming or forestry can be used for the development of agriculture and forestry energy.

在保证粮食安全的前提下，农作物秸秆和能源作物则是生物质能的重要原料，我国农作物秸秆资源丰富，仅三大粮食作物每年就可以产生5×10~8t左右的秸秆，除了部分还田以保持土壤碳含量外，尚有可用于生物能源的部分，此外我国尚有近1×10~8 hm~2宜农、宜林荒山荒地，可用于发展能源农业和能源林业，而且我国能源农林业物种资源非常丰富，农业主要有木薯、甘蔗、甜高粱、油菜、花生、向日葵等，林业有漆树科的黄连木，无患子科的文冠果，大戟科的小桐子，山茱萸科的光皮树等，以此为原料可以进一步加强我国的生物液体燃料等的生物质能利用方式。

Results We found that in all individuals'blood there are an amount of leucocytes parasitized by some moving-ac-tively tiny organisms,which even were found in some of the individuals'blood platelets.After dying we had observed the extracellular fluid of leucocytes and blood platelets.Analogically,in some plant juice and tissue cells we had also found the similar tiny organism,which had an ability to survive under the heat of90℃for30minutes.

结果 观察发现所有人血液中都能找到不同百分比的白细胞内有运动活泼的微小生物寄生，部分人血小板内也有，染色后还能观察到白细胞和血小板的外浆，在部分植物的汁液和细胞中也能看到类似的微小生物，这种微小生物还能耐受90℃高温30min以上。

There are plant stems in the middle of the concretions. The contents of fossils such as crinoids, bivalves, ammonoids and conodonts in the concretions are notably higher than those in rocks around the concretions. Many fossils are directly attached to the plant stems.

这些结核中部都有植物茎干，结核内的海百合、双壳、菊石、牙形刺等生物化石含量明显高于结核周围的岩石，且有许多生物化石直接附着在植物茎干上。

The possibility of researching gene mutation with the technique of gene chip was discussed. A new imagination to randomly determine DNA sequence in different living beings with the technique of gene chip was advanced. In this way, whether the encoding sequence gene in DNA of eukaryon organism has some regularity was studied.

进而提出新设想——采用基因芯片技术对不同生物群体随机抽样进行DNA测序，从而探讨在真核生物DNA分子链上编码序列遗传基因的变化是否有规则而非随机的，非编码序列遗传基因是否为生物进化过程中曾经有表达能力的结构基因，并分析可能获得的结果。

I believe that the existence of natural selection decide the way of life, there are biological or cell biological membrane is the first origin of life-life product of evolution and development; no biological membrane that is non-cell biology is the origin of life re-evolution of life and development.

笔者认为自然选择决定生命存在的方式，有膜生物即细胞生物是生命最初起源的生命体进化和发展的产物；无膜生物即非细胞生物是生命再度起源的生命体进化和发展的产物。
