The present invention relates to a textured yarn with different shrinkage and excellent suede effect, wherein at least one or two kinds of two-component composite yarn having a monofilament fineness of 0.001 to 0.3 denier after dividing or extracting an extraction component are twined around a thermoplastic multifilament yarn, 2 to 350 loops per meter of the two-component composite yarn of at least 1.0 mm in length are formed on the surface of the textured yarn, and more than 95% of the two-component composite yarn loops of at least 1.0 mm in length has a length of 1.0 to 2.5 mm.

本发明涉及具有不同缩率和出色麂装饰效应的变形纱,该变形纱中,在可提取组分分离或提取之后具有单丝细度为0.001至0.3旦尼尔的至少一种或两种双组分复合纱缠绕在热塑性复丝纱周围;每米双组分复合纱2至350个长度至少为1.0mm的弧圈在变形纱的表面上形成,且95%以上的长度至少为1.0mm的双组分复合纱弧圈具有1.0至2.5mm的长度。

Therelationship of the amount of catalyst and the ee% of product was seen to be negative nonlin-ear. Catalyst 3 was used in the enantioselective addition of diethylzinc to aromatic aldehydesand gave good results. The configuration of products was determined by the configuration ofthe catalysts' chiral carbon linked with hydroxy group. Using β- amino alcohols bearing only one chiral center as catalysts for the enantiose-lective addition were studied. D-N, N-dialkyl-2-amino butanol gave poor catalytic effect be-cause of their structure. The configuration of the product is the same as the catalyst. Anotherkind of β- amino alcohols - phenylglycine derivatives and valine derivatives have chiralcenter on the carbon linked with amino group. Catalyzed by-phenylglycine derivatives 6,7, 9, 10, the reactions gave satisfied results. The optical yields exceeded 80%.

在探讨了含有两个手性中心的β-氨基醇之后,选择了只有一个手性中心的β-氨基醇,一是手性中心为连羟基的手性碳原子:D-N,N-二烷基-2-氨基丁醇;二是手性中心为连氨基的手性碳原子:D-苯基甘氨酸衍生物和L-缬氨酸衍生物。D-2-氨基丁醇的催化效果不太好,这与其结构的空间位阻较小有关系,反应产物与连羟基手性碳构型一致;由苯基甘氨酸和缬氨酸出发合成五种β-氨基醇6-10,研究了不同ee%的-6作用下的二乙基锌-苯甲醛加成反应,发现该催化剂具有不对称放大效应;-7,9,lO的催化效果也比较令人满意,光学产率80%以上,所得产物构型与催化剂构型一致。

Because in general there is no soft zones notebook, it is necessary to use DOS software under inspection is very difficult in general, Chinese multi-DOS startup disk U emergence 1.0 solved this problem, these two software will be able to view the notebook under DOS information, but now the use of DOS software testing is very scarce, you can find basically no way for the laptop, currently only found in relatively good AIDA16 2.10 +, Fortunately, now in the testing machine under DOS situation rarely encountered, but prepared to react to them (tell the truth, should there be any problem is basically parallel distributors will not let you casually testing machine software, which directly go for a well).

因为现在笔记本一般没有软区,要使用DOS下的验机软件一般很困难,中文多功能DOS启动U盘 1.0 的出现就解决了这个问题,以上两个软件配合使用就可以在DOS下查看笔记本的信息了,不过现在在DOS下使用的验机软件十分稀少,可以找的到的基本上没法用于笔记本电脑,目前只发现了AIDA16 2.10+比较不错,好在现在在DOS下验机的情况也很少遇到,不过有备无患嘛(说实话,如果真有问题的话基本上水货经销商是不会让你随便软件验机的,这种情况直接走人换一家好了)。

From the map we can know:〓-N is mainly from the catchment above Yichang Station, especially Chengdu Plain;〓-P are from populous region in streamside.〓 is high above Jinshajiang river and in Guizhou, Sichuan region catchment, which was tied up human farming; the content of silicon in water is controled by weathered process.

The area threatened by landslide accounts for 1/4 or 1/5 of the area of national land, landslide activity enter new activeness issue on a large scale in recent years,these landslide once happen,will bring unestimated losses.but if we can accurately forecast the time of the landslide 's happ

这些滑坡一旦发生带来的损失将是无法估量的。但是,如果能比较准确地预报滑坡发生的时间,则可采取相应的防治措施,防患于未然,将滑坡灾害造成的损失减少到最低点。基于以上目的,本论文针对滑坡预报中存在的两个关键问题展开了研究,一、如何有效地剔除影响滑坡预报准确度的虚假噪声;二、如何根据各个预测模型的预测结果整合出一条综合信息。在

The results showed that functional nanometer ITO powders of 30-50nm size with dispersion performance can be prepared. The condition is that indium salt concentration is 88mmol/L, SnO2/In2O3 =5.3wt%, reaction solution PH value is 8, The precursor are thermally reduced at 450 ℃ under hydrogen gas ,at the sametime adding 6at.% KC1 salt to indium tin salts. Thus, satisfactory and stable dispersion of ITO particles in aqueous solution is obtained only through simple mechanical force.

The silica surfaces polished with ion beam of 400ev energy and 100mA density in 35°incident angle for 2hrs was found to have a roughness less than 0.5nm . The SFM was also used to measure the surfaces to be bonded by SAB method and the deformations of the surfaces during contact each other. The micro roughness of the surfaces was found to produce great effect on the SAB strength. The rougher the surfaces are, the weaker the bonding forms.
