A 2D two phase horizontal fracture model was established when studying hydraulic fractures for the requirement of shallow reservoir stimulation in this block; and a 3D two phase model has been built for numerical simulation of a reservoir with five-spot pattern without considering vertical fracture flow. The impacts of horizontal fracture half length and flow conductivity on recovery factor and ultimate recovery factor are studied for some certain injection and production conditions. The parameters of hydraulic fracturing are optimized.

根据该区块浅层油层改造的实际需要，研究水力裂缝时建立两维两相的水平裂缝模型，不考虑裂缝垂直方向上流动，建立了五点井网条件下三维两相油藏数值模拟模型，研究了水平裂缝半长和导流能力对油井产量、注采条件下的采收率和最终采收率等指标的影响，优化了水平裂缝参数。

Sativa meal and both weight gain rate and relative growth rate also increased significantly. The above indexes of fish fed 4% and 12% M. sativa meal were higher than those of fish fed 16% M. sativa meal and were lower for fish fed fresh M. sativa than that of the control group. 2 With increased levels of M. sativa meal in the diets, crude protein content in the muscle of fish fed M. sativa meal increased significantly, while EE and cholesterol were significantly decreased and moisture showed a quadric curve variation. Fish fed fresh M. sativa had no improvement in comparison to the control group. 3 Protease and amylase in foregut, midgut, hindgut and hepatopancreas of C. carpio increased with increased M. sativa meal but the variation was not linear.

试验Ⅰ、Ⅲ组的上述2项指标高于对照组，试验Ⅳ组低于对照组，苜蓿鲜草组低于对照组，但差异均不显著。2和对照组相比，添加苜蓿草粉显著或极显著提高了禾花鲤肌肉中粗蛋白质含量，随着苜蓿草粉添加水平的增加，肌肉中粗脂肪和胆固醇水平显著下降，肌肉中水分含量呈先降后升的二次变化趋势，苜蓿鲜草组的肌肉中粗蛋白质、粗脂肪含量和胆固醇水平无显著变化。3添加苜蓿草粉后对消化道各部位蛋白酶活性及淀粉酶活性有促进作用，均呈先升后降的变化趋势，其中试验Ⅱ组的酶活性最高。

The results showed that fruit bud differentiation needs the high Z、ZR content and low IAA content,meanwhile need the high ratio of CTK to GA 3,CTK to IAA and CTK to ABA.

Applied with test of potted plant and measurement absorbency for study response of the contents of photosynthetic pigments of slash pine's half-sib under water stress. There are 7 families comparison with general slash pine. The contents of photosynthetic pigments are mensurated under feebleness water stress while soil water content is 55% to 60% and moderate water stress while soil water content is 35% to 40% and heavy water stress while soil water content is 20% to 25%. The test result indicate that either water grads or families of chlorophyll and chlorophyll a and chlorophyll b and Chla/Chlb and carotenoid and Caro/Chl are mighty notable difference. The Chl and Chla and Chlb and Chla/Chlb little drop from normal soil water to initial water stress. Then drop obvious with increased water stress. The Caro and Caro/Chl little drop firstly from normal soil water to initial water stress,then up in metaphase water stress,after drop in evening water stress. The Chl and Chla and Chlb and Chla/Chlb and Caro of slash pine'half-sib are over general slash pine. The Chl and Chla and Chlb and Chla/Chlb and Caro of 464 and 1027 are over average value of slash pine's half-sib under water stress. The Caro/Chl of 609 and 46 are over average value of slash pine's half-sib under water stress.

为研究湿地松半同胞家系光合色素对水分逆境的响应，采用盆栽试验和吸光度测定方法，以湿地松普通种子为对照，测定了七个湿地松优良半同胞家系在弱度水分胁迫（土壤相对含水量为55%~60%）、中度水分胁迫（土壤相对含水量为35%~40%）和强度水分胁迫（土壤相对含水量为20%~25%）条件下的光合色素，对湿地松优良半同胞家系在不同水分胁迫条件下的光合色素进行了研究，结果表明：无论是不同水分梯度还是不同家系水平，Chl、Chla、Chlb、Chla/Chlb、Caro、Caro/Chl均有极显著差异；从正常水分至水分胁迫初期Chl、Chla、Chlb、Chla/Chlb稍微下降，后随着水分胁迫程度的加深下降较快，从正常水分至水分胁迫初期Caro、Caro/Chl先稍微下降，胁迫中期上升，胁迫后期下降；所有半同胞家系的Chl、Chla、Chlb、Chla/Chlb、Caro高于普通种，在水分胁迫条件下家系464、1027的Chl、Chla、Chlb、Chla/Chlb、Caro高于家系的平均水平，家系609、46的Caro/Chl值高于家系的平均水平。
