Through comparing the Ar (e,3e) double ionization experimental results at low collision energy with the theoretical calculation based on the first Born approximation which include the first order mechanisms SO and TS1, the symmetry breaking about the direction of the momentum transfer shows that the non-first order effects (such as two-step 2 mechanism) play an important role.

通过比较Ar在低碰撞能量下的(e ，3e)双电离实验结果和基于包含一次作用机制SO和TS1的一阶波恩近似的理论计算结果，表明在动量转移方向上对称性的破坏显示非一次效应(例如二型两步作用机制)起非常重要的作用。

The rhythm of the work song of the boatman in Xiajiang is brisker , it is not outstanding that the power of the beat is compared with, to is it count comparatively flexible to take small matter, present repeated dense wave type move forward constantly, melody change range to be relatively little.

在这样的集体体力劳动过程中，船工号子主要起统一步伐、统一意志、鼓舞情绪的作用。如果没有这类歌声来激发船夫们的斗志，统一步伐，那么是很难渡过险滩的。船工们唱起号子来了，就忘了疲劳，正所谓"不喊号子不起劲，打起号子抖精神"。

In my opinion, Cu complexes with unsaturated alcohol to form a complex compound; the nitrogenous compound introduced serves as the complex compound's stabilizing agent and reduces activation energy of reaction; TMPO serves as oxygen carrier and displays it's selective oxidation function. This new method and mechanism also demonstrates significance to other similar organic reactions.3 In the chlorohydrin reaction, NaCIO is replaced by Ca2see Chapter4.4.3.4(2 .A, this method hasn't been reported in previous literature,which exerts more buffer action to the react system, the yield increased from 52% to 88.6%; at the same time it solve the problem of poor stability and low percentage composition of NaCIO.

认为：CuD与烯醇形成络合物：含氮有机物的引入起到稳定络合物，降低活化能的作用：而TMPO则充当携氧子起传递氧的作用，并具有选择氧化功能：这种新的方法和理论对类似的反应(不饱和醇类在络合体系下选择性催化氧化为对应的醛也具有重要的指导作用。3在异戊二烯的氯醇化反应中，用次氯酸钙代替次氯酸钠见第4章4.3.4(2.A，本方法未见文献报道，使反应系统更加温和，收率由52%提高到88.6%：并解决了次氯酸钠稳定性差、有效氯含量低的实际问题，具有重要的实用意义。

EMF of 50 Hz frequency and 0.8 mT intensity can change intracellular free calcium ion concentration of bone marrow mesenchymal stem cells, and the change play a key role in the cellular proliferation and play a partial role in the differentiation of bone marrow mesenchymal stem cells into osteoblasts.

在50 Hz、0.8 mT电磁场作用下，骨髓间充质干细胞Ca2+内流发生变化，且该变化在骨髓间充质干细胞向成骨方向分化过程中产生部分抑制作用，在促其增殖过程中起主导作用。

The most appropriate catalyzed temprature and pH for it is 60 ℃ and 5.5 respectively. It has the extreme stability at the temperatures no more than 50 ℃.The CMC-Na has the protective effect on the cellulase. The pH stability range of the purified cellulase is 4 ~ 8. Zn2+, Ca2+, Mg2+, K+, Li+ can ativate the cellulase. And cellulase can mainly decompose CMC and salicin, but can decompose other substrates feebly.

对这个组分的催化性质进行了研究，该酶的最适催化温度60 ℃，pH值为5.5，在50 ℃以下酶的稳定性较好，70 ℃条件下底物对酶有较强的保护作用，该酶的pH稳定性范围为4～8， Zn2+，Ca2+，Mg2+，K+，Li+对酶活有促进作用，Mn2+、Co2+、、Fe2+、Fe3+对酶活起抑制作用，酶对CMC-Na和水杨素有分解作用，而不分解脱脂棉和滤纸。

Those rarely refer to the researches about water pressure function mechanism. In fact, the water flow intrudes upwards with a loss of the distance water and energy wastes for splitting rocks when confined groundwater intrudes upwards through coal seam water-resisting layer. The water flow under the coal seam scaleboard consumes more energy after it intrudes at a certain height.

实际上，煤层底板高承压含水层水沿隔水底板岩层向上导升过程中，存在一定的沿程水头损失和劈裂岩体裂隙的能量损耗，下伏含水层高压水在底板隔水层下部劈裂导升一定的高度后，在导升段的能量消耗很大，这时作用于有效隔水层段下部的实际水压已远远小于含水层中的观测水压，真正作用在有效隔水层上的水压为残余水压P_c，对底板有效隔水层起破坏作用的有效水压力亦应为残余水压。

Different brain regions played different roles in digital memory tasks with different terms, and might be involved in different stages. Dorsolateral frontal lobe with left predominance might play more important role in the digital working memory, and the parietal lobe might be more important in the long-term digital memory.

The results of the effect on HSV-2 virulence experiment and the sample-canceling experiment showed that the four sulfated oligosaccharides had no virucidal activity to HSV-2 but inhibition activity.

初步探讨了低聚糖硫酸酯的抗病毒作用机制，由不同时间加药实验结果推测四种低聚糖硫酸酯具有类似的作用机制，可能作用于HSV-2与细胞的吸附阶段，不能抑制病毒在细胞内的复制过程；低聚糖硫酸酯的作用对象为病毒；对病毒毒力的影响实验和撤药实验说明四种低聚糖硫酸酯不能杀灭HSV-2，仅起抑制作用。

Reefs, reef-mounds and lime mud mounds are all carbonate buildups, and the reefs and banks are important targets for petroleum exploration The reefs, banks and mounds should be divided from each other not only in theory, but also in exploration practice, because of so many differences in sedimentary compositions, fabrics, environments, distribution in time and space, and the characteristics of petroleum geology If the original reef or bank itself was fine reservoir rocks, then it would become a better reservoir after the reservoirconstructive diagenesis The formation of a high quality carbonate reservoir is controlled by two factors: the sedimentary microfacies and the reservoirconstructive diagenesis The first is the basis for the formation of a high quality reservoir, and with the high energy reefbank facies as the best; the latter includes the cataclasis, the dolomitization and the karstification The dolomitization and karstification are the best for the formation of a high quality reservoir The karstification has the widest distribution, profoundest effect, and plays a vital role in the high quality reservoir forming The karst types are quite rich in the limestone reef or bank reservoir, including synsedimentary karst, penesedimentary karst, supergene karst and hydrothermal karst, and so does the dolomitization reef or bank reservoir The formation mechanism of synsedimentary karst and penesedimentary karst is related to the short time exposing and leaching of the cyclical highfrequency shallowupward sequence when the reefs or banks are forming The supergene karst is controlled by the exposing and leaching of tertiary cyclic sequence type I interface after the reefs or banks forming Thus, there developed a great deal of secondary corrosion pores, corrosion fractures and huge caves besides some original pores remained in the reef and bank reservoir Scarcely there are any original effective pores in reefmounds and lime mud mounds, especially in senkes among mounds, but secondary pores could be formed by karstification, and there would likely develop source rocks with high organic abundance

礁、礁丘、丘同属碳酸盐建隆，礁、滩是重要勘探目的层。但各自在沉积组分、组构、环境和时空分布，以及油气地质条件上迥然不同，因而无论从理论还是勘探实践上，都有必要将其各成体系划分开来。礁滩自身为好储集岩，当建设性成岩作用叠加后可形成好的储层。碳酸盐岩优质储层形成，主要受沉积微相与建设性成岩作用两大因素控制。前者是基础，并以高能的礁滩相带为最好；后者主要包括破裂、白云石化和溶蚀三大类，并以白云石化或溶蚀为最优，其中的溶蚀分布最广泛、影响最深刻而对优质储层形成起决定性作用。礁滩储层中的古岩溶类型最为丰富多彩，包括同生期、准同生期、表生期和埋藏期热流体岩溶的所有类型，白云岩化礁滩体也不例外。其中，同生准同生期岩溶的形成机制与礁滩沉积时高频层序旋回向上变浅序列的短暂暴露淋溶有关，表生期岩溶则受控于礁滩沉积后三级层序旋回Ⅰ型界面的暴露淋溶。由此，导致礁滩储层中除了可以也是唯一保存原生孔隙外，还发育了次生溶蚀孔洞缝和大型溶洞。礁丘、灰泥丘尤其是丘间洼地中发育高有机质丰度烃源岩；它们自身没有有效的原生孔隙，但岩溶作用可以形成次生孔隙。

The studies on metabolic enzymes、synergists and neurobioassays suggest that the monooxygenases、esterase and decreased nerve sensitity are involved in resistance to pyrethroids in the resistant HJ-R strain . The resistance to both organophosphorus and carbamate insecticides is mainly caused by metabolic mechanisms. The significantly synergistic effects of Pbo infer that the resistance to carbamata may be principally attributable to monooxygenases detoxification.

代谢酶系、增效作用以及神经电生理研究表明，HJ-R种群对拟除虫菊酯类杀虫剂的抗性是由多功能氧化酶及酯酶代谢增强、神经敏感性降低几个因子综合作用的结果；对有机磷、氨基甲酸酯类杀虫剂的抗性主要是由代谢机制引起，与靶标部位敏感性降低机制抗性无关，Pbo对HJ-R种群突出的增效作用，表明多功能氧化酶代谢在对灭多威的抗性中可能起主导作用。
