难解决的

To stationmaster, everyday the thing of numerous and complicated held major working hours, and simple put in the user 's charge for discharge, be megillah simplification important solve a method, because analyse the issue that user demand is a special trouble, everyday by tens of thousands the person that browse lands a website, shut a browser again after that, the visitor that stationmaster confronts a body to conceive all sorts of purposes people, go to user demand accurately very hard individual, and it is difficult that simple statistical data also makes what summary user behavior goes special, the some of the Jiangsu Xuzhou area that how can separate out divide to landed a website 10:20 below just think does the user leave the reason with real website quickly?

对于站长而言，天天纷繁的事物占据了大部分工作时间，而简单的将用户归为流量，是将复杂事情简单化的重要解决手段，因为分析用户需求是一件非常麻烦的事情，天天成千上万的浏览者登陆网站，而后又关闭浏览器，站长面对身怀各种目的的访客们，很难将用户需求精确到个人，而简单的统计资料也使得总结用户行为变的非常困难，试想下如何能分析出10点20分登陆网站的江苏徐州地区的某一位用户快速离开网站真正的原因呢？

With the increase in CO(NH2)2 concentration,the molecular weight significantly increased,and the best concentration scope of DMAEMA was 0.06%-0.10%.Inaddition,the agents for preventing cross-linking were used to prevent the cross-linking reaction and it content was not allowed too high,and the best concentration scope of sodium acetate(the regulator of molecula weight)was

在此中和度下，AMPS的适宜用量范围为AM的75%～16.25%；AA的适宜用量范围44%～55%；(NH4)2S2O8的适宜用量范围为AM/AA/AMPS总量的0.07%～0.12%；分子量随CO(NH2)2的增加而明显升高；甲基丙烯酸N，N-二甲氨基乙酯的适宜用量范围为0.06 %～0.10%；使用抗交联剂可以解决产品交联造成的难溶问题，但加入量不宜过多，否则分子量会下降；分子量调节剂醋酸钠的用量在1.24 %～1.54%范围内可以使产品的分子量达最佳值。

In acid pulp, the depressing abilities of reagents on diaspore are in the order of hydroxamic acid starch＞dialdehyde starch＞carboxymethyl starch＞cationic starch＞primary starch. In addition, hydroxamic acid starch and carboxymethyl starch can activate kaolinite without influence on the recoveries of pyrophyllite and illite, so the two reagents have great potential and prospect to be the depressant of diaspore and the activator of kaolinite in bauxite reverse flotation.(3) By oximation of the copolymer of acrylamide and methyl acrylate, hydroxamic acid polyacrylamide is synthesized.

3对丙烯酰胺和丙烯酸甲酯的共聚物肟化制得氧肟酸聚丙烯酰胺，将它同非离子聚丙烯酰胺、阴离子聚丙烯酰胺、阳离子聚丙烯酰胺和两性聚丙烯酰胺分别应用于四种矿物的单矿物浮选试验，结果显示，改性聚丙烯酰胺对一水硬铝石、高岭石和伊利石均具有活化作用，其中，药剂对高岭石的活化最强，使它的回收率在整个pH值范围达到80％左右，在一定pH条件下超过一水硬铝石的回收率，解决了高岭石难浮选的问题。

The study will develop the important research domain in the high efficiency grinding which has great potentialities, considering that the increase of heat transfer efficiency means an synchronous increase of the limit material removal rate under the condition of grinding unburn, therefore the further perfection of this study will not only increase the available material removal rate to a new level, but also solve the workpiece burn problem of the difficult-to-machining materials in the high efficiency grinding, which has great technical and economical significance

本项研究可望开拓高效磨削的极富潜力的重要研究方向，考虑到换热效率的提高本身也就意味着磨削时不发生烧伤的材料极限去除率的同步提高，因而进一步完善此项研究不仅可望将现有高效深切磨削的材料去除率提高到一个新水平，而且将有效解决难加工材料的高效磨削问题，其技术经济意义十分重大。

The industrial test for Lanping lead-zinc oxidation mine was carried out in this paper.The results showed that too low recovery rate of zinc was not induced by the flotation process of oxidation zinc mine,and the key point of solving the problem lied in how to reduce the produce rate of gangues and how to increase the recovery rate of the metals in gangues.The economic benefit of this process was also evaluated,the result showed that the economic benefit was obvious when the ores of Jiaya Mountain were trea...

对兰坪铅锌矿氧化矿进行了500t/d的工业试验研究，结果表明，氧化锌回收率较低的原因并非氧化锌浮选工艺的问题，如何降低矿泥的产率和能否回收矿泥中的金属将是解决兰坪难选氧化铅锌矿的关键所在，同时也对该工艺进行了经济效益评估，采用现行工艺处理架崖山工业矿具有一定的经济效益，在进一步完善现有工艺的基础上，具有一定的应用前景。

Kempers' study , the more layers the mesh screen type had, its resistance against gravity was higher, but its heat resistance and flow resistance were comparatively augmented. As mentioned in the preceding paragraph, it is extremely difficult for a single micro structure based on any of the three types to possess both low flow resistance and strong capillary force. Faced with this fact, the researchers have tried to mix the three micro structures in Table 2 into as many combinations as possible so that a composite micro structure with low flow resistance and great capillary force may be fabricated. After a thorough analysis, the groove combined with sintered metal or mesh screen has been found to be a better alternative. However, the groove combined with sintered metal will raise the flow resistance of the channel, and the aluminum substrate employed in this research cannot be sintered into a micro structure. As a result, the groove combined with mesh screen is finally chosen as the composite structure to enhance its capillary force and at the same time maintain its high permeability. In this way, the heat pipe will not fail due to the working angles.

Kempers 的研究当中提到，当网格结构越多层时，其对抗重力的能力也越强，但相对的其热阻以及流阻也越高，就如同前段所述，我们很难在单一结构当中找出一流阻低且毛细力之微结构；因此本研究便以表2中之三种微结构进行组合，找出一低流阻且毛细力强之复合式结构，经分析发现，沟槽搭配烧结以及沟槽搭配网格为较佳之组合方式，但由于烧结搭沟槽构造将会提高流道之流阻，且本研究使用铝做为基材，并无法使用烧结最为其微结构，故将采用网格搭配沟槽之复合式结构提高结构的毛细力，并维持沟槽结构的高渗透性，解决因角度造成热管失效的问题。

Inwheat intercropped with soybean not only N situation could be improved butalso P situation could be.2In intercropping,the pH of soybean rhizospherewas decreased by increasing the R-Apase activity,which could decelerate thetransforming and fixing P fertilizer.3In both monoculture and intercroppingsystem,the soil pH of rhizosphere was affected by cropping system at two Plevel which only 0.1-4mm distance from the root surface,but the effect of S-Apase activity in the rhizospher soil by cropping system was less than3mm.In effect,the rhizosphere P was really available nutrient,and applyingP to rhizosphere was effective ways to reduce the P nutrient competition.4Inwheat/soybean intercropping,the peak stage of reduction ability of roots wasthe same as that of the root growth,so that the time compensation appearedin intensity of nutrient absorption.

间套作大豆、小麦、玉米根系Apase的差异又反映出大豆利用土壤磷的潜在能力最大，而玉米最小，可见禾谷类的小麦与大豆间套后不但能改善小麦的氮素营养状况还使磷素营养也得以好转。2）间套大豆根际pH值的下降，导致磷肥施入土壤后形成〓-P的比例显著提高，转化成〓-P等难溶性磷减少，说明间套的大豆能减缓肥料磷在土壤中的转化和固定，减少磷素向无效化方向转化。3）复合群体根际土壤pH值的影响一般只发生在0.1-4mm的根际微区，而土壤磷酸酶的影响供磷与否在距根表3mm以外都无多大差异，说明根际磷才是真正有效磷，根际施磷是解决磷素竞争的有效途径。4）。

I'm wishing on a star And trying to believe That even though it's far He'll find me at Christmas Eve I guess Santa is busy Cause he never comes around I think of him when Christmas comes to town The best time of the year When everyone comes home With all this Christmas tear It's hard to be alone Putting up the Christmas tree With friends you come around It's so much fun when Christmas comes to town Presents for the children wrapped in red and green All the things I've heard about, but never really see No one will be sleeping on the night of Christmas Eve Hoping Santa's on his way Presents for the children wrapped in red and green All the things I've heard about, but never really see No one will be sleeping on the night of Christmas Eve Hoping Santa's on his way When Santa's sleigh bells ring I listen all around The herald angels sing I never hear a sound And all the dreams of children Once lies will all be found That's all I want when Christmas comes to town That's all I want when Christmas comes to town .

我希望在一星并试图相信即使它的远他会发现我在圣诞节前夕我猜圣诞老人正忙原因，他从来没有绕过我认为他在圣诞节都到城里来这一年的最佳时间当每个人都回家撕裂有了这些圣诞很难独自张贴的圣诞树与朋友你来解决这是非常有趣圣诞都到城里来列出在红色和绿色包装的儿童所有我听说过，但根本看不到的东西没有人会睡在圣诞节前夕的夜晚希望圣诞老人的途中列出在红色和绿色包装的儿童所有我听说过，但根本看不到的东西没有人会睡在圣诞节前夕的夜晚希望圣诞老人的途中当圣诞老人的雪橇长鸣我听周围天使唱的先驱我从来没有听到声音和所有孩子的梦想一旦谎言都会发现这就是我要当圣诞都到城里来这就是我要当圣诞都到城里来。

If a "reasonable" notion of database consistency is to be supported (I.c. the database system is to enforce it automatically), there are bound to be" conflict" situations where one transaction comes into an access conflict against some other transaction. If await is to be avoided,some means of a negotiated settlement of the conflict must be provided, thereby dragging the users into the details of concurrency control.The single-database model is more appropriate-ate than the multiple-database model in an environment where it is difficult to determine in advance logical partitions of the database that correspond to work to be performed, and the users closely cooperate.

如果一个数据库一致的合理观念要得到支持（即数据库系统要自动实行这个观念）、一定会有矛盾的情形产生、在这种情形中一个业务与其它业务产生存取矛盾如果要避免等待，就必须提供某种协商解决矛盾的方法，从而迫使用户详细了解并行控制单一数据库模式在某一种环境中比多个数据库模式更恰当，在这个环境中，要事先确定与要执行的工作相适应的数据库的逻辑分割是很难的，同时用户们又紧密地合作在一起。

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。
