We have constructed a bivalence expression vector with SsNHX1 and AVP1 and transformed them into Arabidopsis. The results showed that the transgenic Arabidopsis plants 101 and 127 grew much better than wild type plants in the medium containing 100 and 200 mmol/L NaCl, which further indicated the important roles of Na〓 compartmentalization in vacuoles on plant salt tolerance.

The results showed that plastic deformation at both -70℃ and 180℃ made the dislocation density of AISI304 stainless steel increase with the increase of deformation. Martensite phase transformation was induced for deformation at -70℃, whereas it was not at 180℃. As the dislocation density increased, the breakdown potential of AISI304 stainless steel's passive film became a little more positive. As martensite phase content increased, it became more negative and pitting corrosion resistance decreased.

结果表明：加热180℃和低温-70℃条件下塑性变形均使AISI304不锈钢中位错密度随变形量增大而增加，AISI304不锈钢在-70℃条件下塑性变形时部分奥氏体相转变为马氏体相，而在180℃条件下塑性变形时不发生马氏体相变；位错密度的增加使AISI304不锈钢钝化膜的击穿电位略微正移，而马氏体相的增加使击穿电位呈负移趋势，材料耐孔蚀性能降低。

In a detailed historical narrative, we explain the process bringing China from the multi-principal governing model to the single-principal governing model in the Qin and Han dynasties. The bureaucratization of traders and the extinction of paladins were the main causes for this transformation.

在此基础上，通过对秦汉之际多委托人治理结构向单一委托人治理结构转变的各项特征事实的分析和模型推演，本文厘清了中国何以走上并锁定在以安全为导向的单一委托人治理形态的初始条件，认为商人的官僚化将社会资源控制力从非主流治理集团牢牢吸纳并控制在主流治理者集团之内，此举消除了各类游侠生存发展的经济基础，对游侠的打击削弱了非主流治理集团的暴力依凭，汉朝以降各大一统时代均不能形成长期独立于政权之外的有规模暴力，是新的治理竞争者不能长期存在从而打破单一委托人治理形态的重要原因。

That deeply discusses the specialty of calcium and fluoride in saliva and plaque, and makes clear the rule of conversion and reciprocity of it will be important meaning to clear the pathogenesis of caries, and advance remineralization of dental, and effectively process the forecast and prevent and therapy of caries.

The bulk density of these peels of root and crops decreased with the increases of milling time could be caused by porosity or capillarity on the surface.

三种样品粉末之体积密度均随研磨时间延长而降低，推测可能原因是三种果皮在微细化处理之后，其表面产生多孔状或表面的毛细现象所致。

The uncovered tracts and the liver wound surface were managed by some of the methods combined such as high frequency electrocoagulation, titanium clamp, suture, hemostatic gauze oppression, argon-beam coagulation, protein glue adherence, and Endo-GIA switcher. The total operative outcome, operating time, blood loss, postoperative complications and postoperative hospital stay were summarized in order to assess feasibility and safety of the clinical laparoscopic liver resection.Results: 1. Laparoscopic liver resection with clamp dissection method needs only the ordinary laparoscopic equipment. It has a low cost but causes a little more bleeding. 2. Laparoscopic liver resection operated by microwave tissue coagulation method had very little bleeding when dissecting hepatic parenchyma. The operative field is clear and the cost is low. It is a safe, convenient and effective method. 3. Ultrasound dissector is a relatively ideal appliance for laparoscopic liver resection at present because ofless bleeding during operation. But the speed is slow thus prolongs the operation time. Its separating intensity is not strong enough, and it can only be applied to patients without hepatic cirrhosis. 4. Ligsure has clamp dissection and electrocoagulation functions. It can carbonize hepatic tissue including the tracts whose diameters are less than 7mm. It has some advantage in dissecting. However, it has the shortcomings of the clamp dissector during coagulating. 5. Hand-assisted laparoscopic liver resection can make use of the flexibility and feeling of the operators left hand.
