Considering linear and O-linear predictable variables, the author investigates optimal prediction problems by the trace of matrix. A few necessary conditions are derived and accordingly optimal linear and optimal O-linear unbiased predictors, which are unique with probabitity one, are obtained respectively by the author.

对于一类线性可预测变量和Φ-线性可预测变量，作者在矩阵迹意义下研究了一般增长曲线模型中最优预测问题，找到了其存在最优预测的几个必要条件，并在给定的条件下分别得到了最优线性无偏预测和最优Φ-线性无偏预测，而且还证明了它们在几乎处处意义下的唯一性。

Seepage velocity smoothly change from a steady value to a new steady value, the ratio of the new steady value over the original steady value might increase hundreds of thousand times or even more, but it is always finite.（3）Water-inrush goes with the failure of rock strata, but seepage velocity can not increase unendingly, so seepage flow cant be unstable.

研究表明：由于非Darcy流β因子恒为正值，渗流系统总是稳定的；当渗透特性随时间变化时，渗流速度从一稳定值平滑地过渡到一新的稳定值，新的稳定值与原稳定值之比可以增大到几万至几百万倍，但是总是有限的；突水是岩层结构破裂引起的渗流速度快速或急剧变化，但渗流速度不可能无止境地增大，即渗流不可能失稳。

New apomictic plants are enumerated. Genetic mechanism is summarized. The problems in this field and development prospects are discussed.

本文对近几年来无融合生殖新种质资源的发现、主要研究方法、遗传机制和相关基因等方面的最新进展作了介绍，并对无融合生殖研究中存在的问题和发展前景作了讨论。

In returnable system there are kinds of switch styles on positive and negative two group rectification bridger,the higher reliability is no cycle current switching,writer designed the logical no cycle current returnable system.

The gentleman with the hooked nose then muttered certain cabalistical expressions which I was too much frightened to remember, but I recollect that at the conclusion I was given to understand that I was married to a young lady of the name of Frances Fair child, whom I perceived standing by my side, and I hope in the course of a few months to have the pleasure of introducing to you as your daughter in law, which is a matter of some interest to the poor girl, who has neither father nor mother in the world

接着，那位鹰钩鼻的老先生口中念念有词，说了一串神秘的话语。我当时十分紧张，没有记住他说了些什么，只记得在结束的时候，他说我和一个名叫弗朗西丝·菲切尔德的姑娘成了婚。她当时就站在我身旁，希望几个月后能有机会荣幸地把她作为您的儿媳介绍给您。这个可怜的姑娘对此很感兴趣，因为她在这个世界上无父无母

Some data are commemorable still perhaps: The website that I never can flaunt me like others was collected tens of thousands of page, because at present altogether has hundreds of implied meanings only, but my website is in on the line collects; with respect to the Google that be mixed by Baidu the following day the website that I won't flaunt me everyday how many do IP and PV have how many, because everyday actual visit quantity is had pity on less really, but I won't flaunt my website PV=1; how many does my website have to register an user, because the user of my website is for the most part,come, but they often can come back to see; the website that I also won't flaunt me has how many how many implied meaning, the rate that writes because of everybody cannot be caught up with completely duplicate and stickup, but the article that I can assure to the division is started formerly on the website did not borrowed, the article that and once somebody tries in vain,be released borroweds, I will be ruthless ground cutout does not have condone.

也许有些数据还是值得纪念的：我从不会像别人一样标榜我的网站被收录了几万页，因为现在一共只有几百篇文章，但是我的网站在上线第二天就被百度和Google收录；我不会标榜我的网站天天IP和PV有多少多少，因为天天的实际访问量的确少得可怜，但是我的网站PV=1；我不会标榜我的网站有多少注册用户，因为我的网站的用户大部分是靠口口相传而来，但是他们都会常回来看看；我也不会标榜我的网站有多少多少文章，因为大家写作的速度完全赶不上复制粘贴，但是我能保证网站上原创区的文章没有抄袭，并且一旦有人妄图发布抄袭的文章，我会毫不留情地&删无赦&。

The French philosopher Jacque Derrida is the founder of Destructionism Theory and the Ruassian philosopher Bakhtin is the creator of Carnival Poetics. With Derrda's major destructive key words, diffěrance, la dissěmination and the basic principle of Derrda's Character Theory, I analyse the destructive tactics of Wulitou Comedy Movies throughout its conceiption, narration, and performance.

objective to explore the reasonable utilization of cephalosporins in chronic renal failure patients with cephalosporin encephalopathy.method we retrospectively analyzed the clinical characteristics of 29 crf patients,who developed encephalopathic syndrome and was treated with cephalosporin.results the encepha1opathic syndrome include (1)mental confusion in 4 cases;(2)unconsciousness in 2 cases;(3)seizure in 23 cases.physical examination did not show signs of cerebral focal injury.computed tomography of the brain in 29 patients did not show acute lesions.the state of neurotoxicity was completely recovered after discontinuation of cephalosporins.conclusion cephalosporins used in conventional doses or reduced doses can cause temporary encephalopathy in patients with crfwhich might due to prolongation of drug half life.

目的 通过研究慢性肾功能衰竭患者抗生素脑病的发病机制和临床特点，探讨头孢菌素在crf患者中的合理应用。方法 29例crf患者在使用常规剂量或减量使用头孢菌素后出现神经精神症状，诊断为抗生素脑病，将其临床资料进行回顾性分析。结果神经精神症状表现多样：(1)精神异常4例，表现为胡言乱语、烦躁不安、睡眠倒错；(2)意识障碍2例，表现为嗜睡、昏睡、神志不清；(3)癫痫样抽搐23例，表现为肌阵挛、全身抽搐、癫痫样发作；部分患者同时出现几组症状。所有患者均无神经系统定位体征，行颅脑ct检查无急性病变。
