使成碱性

Alkaline lipase Greasex 50L is one of the leather enzyme products of Novo Nordisk AS. After extensive control trials on pigskins, evaluating effects by degree of fat removal and qualities of result leather, we got1 Fat removal rate can be increased by 10%and leather qualities such as napping and softness can be improved by using Greasex 50L together with liming enzyme NUE 0.6 MPX2 Some surfactant together with Greasex 50L is good to fat removal, and the recommended ratio is 0.05%～0.1%∶13 The fat content in the skins is lower after treated with Greasex 50L,which also benefits the successive processes, such as bating, pickling and tanning. As a result, the leather qualities, such as fineness of grain, softness, napping and evenness of dyeing can be improved.

Greasex 50L是诺和诺德公司生产的碱性脂肪酶已在皮革工业中广泛使用，为了更好地应用这种酶制剂，我们对Greasex 50L在猪皮方面的应用条件进行了研究采用对比的方法，用脂肪去除率和皮革的质量作为评价标准，研究结果表明1适量的浸灰酶 NUE 0.6 MPX可使Greasex 50L的脱脂率增大，同时可改善皮革的起绒状况和革身柔软性2一定量的表面活性剂与Greasex 50L配合使用，有利于脂肪的去除，用量为平平加的0.05%～0.1%3 经Greasex 50L脱脂的裸皮在鞣制后油脂含量也较低，有利于后续工序进行，从而使成革粒面平细、革身柔软，臀部起绒得到改善，染色均匀性良好

Methods We isolated and cultured the MSCs, then induced MSCs into osteoblast and checked the osteoblast by RT-PCR; the conditioned medium in different concentration was prepared containing diphosphonate or assemble flavone of drynaria rhizome; with the conditioned medium the osteoblast was cultured; then the growth curve was analyzed and the cytogene (collagenase col Ⅰ) col Ⅰ and ALP expression was detected.

After that the territor ial extensional stress field caused by the plates movement and the mantle upheave etc. makes the Yishu fault system keep on cutting downward tend to form rift valley. The tectonism causes the fairly large-scale invasion of the small neutral -partial alkaline rock-bodies and the gold mineralization in the Linyi area.

燕山中期板块俯冲运动和地幔上涌等因素引起的区域性拉张作用使沂沭断裂继续向下深切张裂，向裂谷性质演化，造成沂南、临沂等地区较大规模中性偏碱性次火山岩型小岩体的侵入和火山喷发，在火山机构内或围绕次火山岩小岩体形成与中性偏碱性次火山岩有关的次火山岩型金矿化。

High-sulfur hot spring water in ancient description: hot spring water from 2500 meters underground granite, dolomitic limestone and gneiss crust between the ancient hot springs, hot spring water has been formed last million years, year-round water temperature of 50-60 ℃, a liter water the sulfur content of more than 2 mg in the rich oxygen, silicon, aluminum, iron, calcium a variety of ancient trace mineral elements, PH value of 7 are weak acid, such as lactic acid in yogurt not only offer intestinal alkaline substances in the change into a weak acid substances, but also have anti-bacterial material substances, inhibition of intestinal bacteria breeding corruption and activities, thereby reducing the intestinal harmful substances on human health has a very good role.

高硫磺远古温泉水质介绍：温泉水来自地下2500米花岗岩、白云质灰岩和片麻岩之间的地壳温泉，温泉水已经形成上亿年，又称&远古温泉&，常年水温50-60℃，每升水中的硫磺含量在2毫克以上，富含氧，硅，铝，铁，钙等多种远古微量矿物元素，PH值7属于弱酸性，如酸奶中的乳酸不但能使肠道里的弱碱性物质转变成弱酸性物质，而且还能产生抗菌物物质，抑制肠道中的腐败菌的繁殖和活动，从而减少肠道内的有害物质，对人体具有非常好的保健作用。

The oxidant 〓 plays indirect role in dissolving gold, and mainly controls the mix potential of Au in the alkaline thiourea solution. In which the "mix potential"is the decisive factor affecting the dissolution of gold. The reaction driving force is enough to have formamidine disulfide oxidize Au to Au〓 at the potential of about 0.4V. And then thiourea molecular complexes with Au〓 ion soon, which causes the fast dissolution of gold in the alkaline thiourea media. The dissolved weight of gold in 0.25 M thiourea solution with 0.05M Na〓SO〓 and 0.1M 〓 of pH 12. 5 by air at the temperature of 303K is 7. 8mg·cm〓 within 1hr.

在碱性硫脲溶金过程不起直接作用，而是通过S〓O〓来控制二硫甲脒有效形成的金在溶液中的混合电位；&混合电位&是影响碱性硫脲溶液溶金与否的决定性因素，在0.4V左右，有足够的推动力致使二硫甲脒氧化Au成Au〓，随后硫脲与Au〓络合形成稳定的络离子Au〓，从而使金快速溶解；温度为303K、pH为12.5时，在含0.05MNa〓SO〓、0.1M 〓及0.25M硫脲的溶液中，鼓入空气，金的溶解量在1hr内为7.8mg·cm〓；铜只有微量溶解，银、镍、铁则几乎不溶解。

Results In define induction envioroment, HPMSCS can diferentiate into lipoblast、after 2 weeks, the induced cells are full of lipid droplet;HPMSCS can differentiate into osteoblasts, after 4 weeks, we can see calcified tubercle in the cells, calcium in the calcified tubercle can be dyed black by Von Kossa and ALP dying is positive reaction above 95%.

结果 HPMSCS在培养基中持续培养后，在特定诱导环境下，成功使其向成脂肪细胞转化，培养2周时，可见融合成团的脂滴充满整个细胞；成功使其向成骨细胞转化，培养4周以上可见明显钙化结节，von Kossa染色可将骨结节中沉积的钙染成黑色，碱性磷酸酶染色呈强阳性反应达到95%以上。

In this method onlydihedral angles were selected as independent variales,a proper target function was minimized by loacl-to-globular optimization,thus these dihedral angles andthe coordinates of six kinds of the backbond atoms (N,HN,Cα,IIα,C′,0) were calculated.

这种方法把肽平面之间的二面角当做独立变量，通过从局部到整体逐渐最优化的方法使适当构造的目标函数最小，计算出这些二面角，以及主链每个残基上六种原子N、H%%^^N%%^^、C%%^^α%%^^、H%%^^α%%^^、C′、O的空间坐标，绘出蛋白质分子的溶液三维结构图案，并成功地把这种方法编写成计算程序DISNMA，且以碱性胰蛋白酶抑制剂为标准结构，得到了很好的验证。

The ordinary clay and tannery sludge along with molten slag that was basic clinker of iron and steel plant were used to produce the ceramic samples.

利用普通粘土、制革污泥和钢铁厂碱性熔渣，研制成陶瓷试样，既解决了制革污泥和钢铁厂碱性熔渣对环境造成污染的问题，又使其得到综合利用，是一种处理制革污泥的新方法。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
