The result indicated that suitable thickness of paddy soil is about 15cm,and for dry arable land it should not be lower than 20cm;The alluvial rivers parent material is the best one to influent the output,the rice fields is the worst with the parent material of slate ground,while the dry and plough land is the worst for its purple sand shale parent material;The paddy rice is best with the acid soil,and the dry crop is the best with the neutral soil;The obstacles horizon exist in 35.2%of the rice fields in research region,and many for middle or top digit obstacles.
结果表明,水稻土的适宜耕层厚度为15 cm左右,旱耕地适宜耕层厚度应不低于20cm;成土母质对产量的影响以河湖沉积物母质最好,稻田以板页岩母质最差,旱耕地以紫色砂页岩母质最差;水稻以酸性土最好,旱作以中性土最好;研究区稻田有35.2%的存在障碍层,且多为中、高位障碍,是影响水稻产量整体提高的主要因素;水稻和旱作都以壤土为最好,其中,稻作怕砂,旱作怕粘;水稻土适宜的容重为1.00—1.29 g/cm~3。

Accord- ing to the observation that the compounds were stable in low pH aqueous solution and their sta- bility decreased when pH increased, and they rapidly decomposed to form α-methylenecyclopen- tanones derivative when pH reached 6 to 7, we postulated that the compounds were unabsorbable in stomack (where pH1-3) and unstable in small intestine (where pH5-8). The decomposed product was indeed inactive.
对Ⅰ类化合物在稀溶液中的稳定性研究表明,低pH时化合物较稳定,随着pH值的升高稳定性逐渐降低,pH6~7时,化合物迅速分解成α-亚甲基环戊酮类化合物,由此而推测Ⅰ类化合物经口给药无效的原因为:它们在强酸性的胃中(pH1-3)呈离子状态,因而不易吸收,经胃的排空运动进入肠道后,随着pH逐渐升高(pH5-8)化合物迅速分解,而分解产物α-亚甲基环戊酮类化合物证明是无效的。

Tumor cells grew actively in the tumor tissues of the control group. Prodrug therapy group: small amount of tumor cells were denatured vacuously,others were infiltrated by lympholeukocyte,and the growth of tumor cells were surspressed.Prodrug themochemotherapy group: what we can see that tumor cells were denatured vacuously, mesoplasts crinkled, cellular boundary disappered, only a small number of tumor cells remained, fibroblast were seen scatteredly, tumor cells were invaded by a lot of lympholeukocyte and eosinophilic granulocyte. Normal liver tissues, stomach tissues, lung tissues, pancreas tissues, small intestine tissues, large intestine tissues showed normal shape.
