But as Lou Crandall of Wrightson ICAP, a research firm notes, Auctions work well when you have a group of bidders for a single set of identical assets. They work less well when you have a single bidder for a group of disparate assets.

但是一家研究机构Wrightson ICAP的Lou Crandall认为：拍卖在一群竞标人争夺一个单一的资产时比较有用，但是在一个竞标人却又一大堆不同的资产时就不太起作用了。

The present invention relates to a coating composition comprising; A at least one polyester oligomer prepared from reactants comprising a 20 60 wt.% of at least one polyol, b 5 30 wt.% of at least one polycarboxylic acid selected from the group of cyclic polycarboxylic acids, the esters or the anhydrides thereof, wherein the carboxyl groups are separated by 3 carbon atoms or less, and from the group of alpha , beta -saturated acyclic polycarboxylic acids, the esters or the anhydrides thereof, and c 20 60 wt % of at least one monocarboxylic acid, the sum of the wt.% indicated for the reactants,, and always being 100 wt.%, and the oligomer being a low-viscosity oligomer having a weight average molecular weight Mw of less than 5,000, and a hydroxyl number in the range of about 200 to about 400 mg KOH/g oligomer, and B at least one polyisocyanate.

本发明涉及一种包含如下组分的涂料组合物：A至少一种由包含如下成分的反应物制备的聚酯低聚物：a20-60wt％至少一种多元醇，b5-30wt％至少一种选自其中羧基被3个或更少碳原子隔开的环状多元羧酸、其酯或酸酐以及选自α，β-饱和的无环多元羧酸、其酯或酸酐的多元羧酸，以及c20-60wt％至少一种一元羧酸，其中反应物、和的wt％之和总是为100wt％，所述低聚物是重均分子量Mw低于5000且羟基值为约200-约400mg KOH/g低聚物的低粘度低聚物，以及B至少一种多异氰酸酯。

In the reaction of a-stannyl radical addition to carbonyl to form six-membered ring, we constructed a sulfonyl group at the a position of the formyl group to inhibit 1,5-H shift in order to increase the cyclization product yield. We obtained 41 % yield of the cyclization product in this system.

在 a-锡基自由基加成到醛基形成六员环的系统中，我们在醛基的 a 位上加入碸基来抑制 1，5-氢转移并提升环合产物之产率，在这个系统中，我们得到了 41 %的环合产物。

cerebral hemorrhage of 46 ventricle grave (be more than 20ml) patient to divide two groups into A, B randomly, a group 22, use microscopical technical ossicle window opens haematoma of skull grave head cleared art + group of;B of art of the drainage outside ventricle 24, in art of drainage of puncture of haematoma of head of grave of be issued to lower levels of CT fixed position + art of the drainage outside ventricle.

The results indicate that there is an important relationship between the substructures of butyrolactone in taiwanin A and its biological activity, we find that the enlargement of structure space at the place of methylene of piperonyl group of taiwanin A may be a way to improve its biological activity.

我们发现taiwanin A结构中的内酯﹝butyrolactone﹞与生物活性有著密切关系，另外还推测它次甲基二氧苯基﹝piperonyl group﹞上的次甲基如果能用空间上更大的官能基取代，是改进taiwanin A生物活性的一个方向。

The demonstrate in can asking to develop a process of course (safeguard a map by development staff for example, a of the ID interfacial element and tiring-room or correspondence of a group of operations rises), what I need to solve now is how to let the system discovers automatically and maintain these relationships Read above oneself problem, discovery had a direct result to be told to the system,"Authority " the ID that is an interface element and the URL that a group of tiring-room serve (take no account of data to visit attributive temporarily), attributive ={id, comId, urls, desc} such, how can problem translate into realize the definition of attributive, let him user input ComId, Urls?

当然可以要求开发过程中指明（例如由开发人员维护一个映射，把界面元素的ID和后台的一个或者一组操作对应起来），我现在需要解决的是如何让系统自动发现和维护这些关系读了上面自己的问题，发现有了个直观的答案对于系统来讲，&权&就是一个界面元素的ID和一组后台服务的URL（暂时不考虑数据访问权限），权限={id，comId，urls，desc}这样，问题转化为如何能够实现权限的定义，让用户自己输入comId、urls吗？

A sub-soil stove, a "pot after another"(produced by the soil, the capacity of small capacity of the tea may be far less than a glass), a group of tea or a cage of fire, a group of tea , a tea and acha guan insanity is all Tanks for all the tea.kang shang sitting in hot, two-wang stove, black tiles tank to boil the tea extremely strong, sipping a population, it is easy comfortable.
