The main function of sucrose is to maintain normal respiration, so it can only be used to join the preservative, and make a good effect in maintaining the water balance of Dianthus Caryophyllus when dealing with 0.01% Phytic Acid +2% S +200 mg/L8-HQC solution; Finally, in the mensuration of Dianthus Caryophyllus fresh weight change, no matter using which the vase planting solution, the fresh weight of Dianthus Caryophyllus increases in the initial phase and then gradually decreases.

结果表明：在花径变化的测定中，经0.01%植酸+2%S+200mg/L8-HQC溶液处理的香石竹在保鲜期间得到最好的保鲜效果，切花的生长状况达到最佳状态；在水分平衡的测定中，结果表明蔗糖溶液对香石竹的水分平衡的保持有负作用，蔗糖的作用主要作用是维持正常的呼吸作用，因此它只能用来加入到保鲜剂中，处理0.01%植酸+2%S+200mg/L8-HQC在保持切花的水分平衡上起到较好的效果；最后在香石竹的鲜重变化测定中，无论什么瓶插液，香石竹切花的鲜重在初期阶段增加，然后逐渐减少，水分的吸收与丧失会有波动，但总趋势是失水量大于吸水量。

The relation between body weight and length could be described by the function: W=0.0098L^(3.0299)(R^2=0.9989), indicating that the body weight and length of one year old Esox lucius grew in similar velocity.

拟合白斑狗鱼体长与体重的关系为：W=0.0098L^(3.0299)(R=0.9989)，其中b接近于3，表明白斑狗鱼的体长和体重处于等速生长。

The 1000-grain weight heterosis was mainly due to the grain fresh weight heterosis at 12 DPA and 22 DPA that the intervarietal hybrid had, and also due to its promotion of 2 kinds of hormone IAA and CTK 12 DPA, the IAA function extended to 22 DPA.

品种间杂种也具有一定的千粒重杂种优势，这与12天、22天籽粒的鲜重优势有关，籽粒发育早期（12天）2种促进型激素IAA和CTK促进籽粒生长，与其获得较大的鲜重优势有关，IAA的促进作用可延伸到22天。

The support of TPN at least for 7 days in gastric cancer patients with significant weight loss and severe malnutrition going to receiving operation maintained the nutritional status and prevented continuous weight loss. The early enteral feeding through jejunostomy tended to increase serum hemoglobin, hematocrit, and iron levels to prevent deterioration from anemia. Additionally, nutritional support gradually improved the immune function of gastric cancer patients by increasing total lymphocyte counts.

对於准备要接受胃癌手术体重明显减轻的严重营养不良病患，给予七天以上的全静脉营养支持，可维持病患之营养状况且避免体重持续减轻；术后透过空肠造口给予早期肠道营养支持，对於血清中的血色素与血比容和铁质有助上升趋势，避免贫血情况恶化；由总淋巴球数的增加发现营养支持可以渐渐恢复病患之免疫功能。

Results compared with model control group,dongbao gantai group, the level of body weight,liver index, tc ,tg, alt,ast in serum in tiaozhi hugan decoction group were lower significantly .the level of hld-c was higher.,the level of mda in tiaozhi hugan decoction was lower significantly, the level of sod was higher significantly（in all group p＜0.01）conclusion it suggests that the pharmacodynamics mechanisms of tiaozhi hugan decoction to fatty liver induced by high fatty diet are lowering body weight and liver index, adjusting lipometabolism, improving liver function and having anti-lipid peroxidation effects.

结果 与病理模型组、东宝甘泰组比较调脂护肝方组大鼠体重、肝指数血清tc值、tg值均降低，hld-c值增高，血清alt、ast、mda值均较低，sod值较高（各组比较p.01）。结论调脂护肝方干预非酒精性脂肪肝的药效机制为：降低体重与肝指数，调整脂质代谢，改善肝功能，抗脂质过氧化。

Chapter 2 discusses the function of optimum array based on the minimum meansquared error principle in CDMA system, the method of produce the reference signal, and proved whether the reference signal is the correspond PN code sequence or respread signal, the result of the array's weight converge can converge the same optimum weight under the condition that the PN sequence in a bit of data is long enough. In this chapter, we finally get the beam pattern and the correlate bit error rate after converge when several CDMA signal arrives in different direction.

本文的主要贡献及创新之处是：首次从理论上探讨了基于最小均方误差准则的最优天线阵在CDMA系统中的多址干扰抑制性能及其参考信号的产生方法，证明了采用有用信号相应的扩频码作为参考信号与采用将解扩信息与扩频码进行重扩频后的信号作为参考信号来调节自适应天线的权值均可使权值收敛于同一最优解。

To overcome target expansion, shape transformation and occas ional frame lost due to the missile phase motion of television guided bombs , a modified weightˉrelated function, t arget tracking strategy, template updating and modifiˉ cation, and tracking point positioning method as well as a predict ion method to solve the frame loss of target were proˉ posed. Based on this, an improved weightˉrelated matching tracking a lgorithm was realized.
