不规律

Wang Fuzhi,on the country,claimed it was one of the forms of the change of the things instead of a universal law,and therefore can not have it formulized.

王夫之依据其神化学说，重新检讨这一命题，认为物极必反并非普遍规律，而只是事物变化的一种形式，不能将它公式化。

ABSTRACT It is because that the excellent acceptors for maize transgenic engineering are insufficient in our country, especially in the southwest mountain areas of china and hereditary variation regularity for the two characters such as efficiency of embryonic callus induction and number of regenerating plant (these two characters were abbreviated to the nduction efficiency and number of regenerating in the following of the paper, respectively), which hint the maize culturing capacity, is not very clear. Therefore, aiming at picking out superior acceptors, we had made systematic researches on the two characters with combing traditional quantitative-character genetic analyzing methods such as single-factor genetic mating design, diallel crossing genetic design, genetic effect analyzing method and the modern molecular locating method such as QTLs'. The main results are followed.(1) 50 superior inbred lines and about 30 crosses in our country, especially in the southwest of China were used for identifying and selecting the superior genotypes in the above two investigated characters under the same culturing condition in 2000 and 2001. There was very significant difference among the genotypes in the both characters. But the two characters were not certainly related. Some genotypes such as 18-599 and 18-599 were very good in them. For some ones such as zong 31, induction was higher than 18-599 and 18-599 in the efficiency, but it was only 1/3 to the later in regenerating number. In some genotypes such as S37, R08, R15, P138, A318, induction efficiency was just about 3% and scarcely any regenerating plants were got. On the whole, hybrids acted better than inbreeds in the both characters.(2) Two kind of inbreeds were selected as parents of the Griffing's method 1. 18-599 and 18-599 and the inbred line zong 31 are one kind because they are not only superior in the characters of maize cross breeding, such as CA, resistance to disease and the important agricultural characters, but also excellent in transformation characters as the induction and regeneration.

针对我国、特别是西南山地所需玉米转基因工程育种优良受体极为匮乏和反应玉米幼胚培养能力的2个主要性状，即玉米幼胚胚性愈伤组织诱导率和胚性愈伤组织绿苗发生数的遗传变异规律十分不清楚的实际情况，本研究从筛选玉米转基因工程所需要的优良受体入手，采用单因素遗传交配设计、双列杂交遗传交配设计、世代基因效应等传统数量性状分析方法，以及现代分子标记定位主效QTL分析方法，对玉米幼胚胚性愈伤组织诱导率和胚性愈伤组织绿苗发生数等2个性状进行了较为系统的分析研究，取得以下主要研究结果：(1)于2000年和2001年通过对我国、特别是西南地区近50份优良自交系和近30个杂交组合，在相同培养条件下，对幼胚培养胚性愈伤组织诱导率和胚性愈伤组织绿苗发生数等2个幼胚培养能力性状进行了筛选与鉴定，发现玉米不同基因型具有完全不同的幼胚培养胚性愈伤组织诱导率和胚性愈伤组织绿苗发生数，但幼胚培养胚性愈伤组织诱导率与胚性愈伤组织绿苗发生数并不具有必然的相关关系，有的基因型，如自交系18-599和18-599在胚性愈伤组织诱导率和愈伤组织绿苗发生数等2个性状都表现相当优异；有的基因型，如自交系综31，仅幼胚培养胚性愈伤组织诱导率性状表现高于19-599和18-599，但在胚性愈伤组织绿苗发生数这一性状则与它们有相当大的差距，仅为19-599和18-599的1/3左右；有的基因型，如S37、R08、R15、P138、A318等玉米自交系不仅幼胚培养胚性愈伤组织诱导率很低，平均仅在3％左右，而且胚性愈伤组织绿苗发生数表现也很差，基本上没有分化成苗。

The dynamical characteristics of a low voltage MicroGrid from grid-connected mode to islanded mode with different distributed generation configuration schemes are analyzed by using simulation method,and the corresponding changing laws of each DG's power,voltage and frequency of MicroGrid are obtained.

通过算例仿真研究了不同分布式电源配置方案下低压微网从并网模式向孤网模式转换的动态运行特性，获得了分布式电源的功率、微网电压和频率的变化规律。如果选择微型燃气轮机作为微网的功率支撑手段，在微网从并网向孤网过渡过程中，系统频率波动较大，且部分分布式电源有可能在低频保护动作下与电网隔离，不利于微网的稳定运行；增加储能设备后，储能设备对于微网的稳定运行可发挥重要的作用。

The interlayer oxidized zone and the concentration of uranium has the typical characters of low temperature geochemical processes. Interlayer oxidized zone can be defined from the bedrock to horizon C under hypergene weathering by such parameters as chemical metamorphosing、index of chemical weathering and index of mineral chemical differentiation.(2)Major elements can be divided into sensitive group、 active、 weak active and inert groups according to chemical metamorphosing parameter and fractional migration potential. For major elements of multivalent in the active group( Fe_2O_3、 FeO) and U, the migration and concentration trend in interlayer oxidized zone is apparent.

层间氧化带形成和铀富集成矿是地下水在低温、常压、开放体系、非平衡状态对围岩长期作用结果，元素含量及其有关地球化学参数在氧化带不同亚带中表现出一定的变化和分布规律，除Fe_2O_3、FeO、Fe_2O_3／FeO外其它元素含量及其参数只在统计学上呈现规律性变化，而不具分带意义，具有典型的低温地球化学作用特点；利用风化作用化学蚀变参数PC值、化学风化指数ICA和矿物化学分异指数ICV将层间氧化带作用界定于表生风化作用的基岩到母质层阶段。

We hope to see change is not man-made, but out of respect for the laws of the market,"the wind at night, moisturizes things in silence" development.

我们希望看到的变化是不是人为的，而是尊重市场规律，&风在夜间，润泽的事情保持沉默&的发展。

I just believe all before my eyes, that is: when closing,"bottom deviation" seriously comes in technical side, in which overselling and overfalling are to rebound at-the-close order, overpurchasing means cashing while falling.

我只相信眼前的一切，那就是：收盘时，技术面严重&底背离&，超卖超跌就抄底反弹，超买就套现下跌，这是&牛头熊身&行情规律，况且经济基本面以及宏观政治不允许市场倒退，下周，市场主力将再次拉动一波更强势的股指拉高行情，股指将再创新高！

On the other hand, a large postclosure settlement is undesirable from a maintenance point of view, since it may lead to surface ponding, development of cracks in soil materials, tearing of the geomembrane, and damage to the geocomposite drainage layer.

为了保证垃圾填埋场的安全可靠，诸如填埋场最终覆盖系统、衬垫系统、渗滤液收集和运输系统不至于因为垃圾土过大的不均匀沉降而破坏等问题，因此，垃圾填埋场的沉降规律一直是填埋场研究中的重要课题。
