本研究描述了不同品种鲤、鲫鱼从出苗到体色形成的发生过程，总结和归纳了不同时期体色变化的异同点，以期为鱼类的体色研究提供理论依据。

Can undertake nutrition of light energy inorganic is divided inside the cell of general alga contain and the light with advanced same plant adds up to green outside pigment, some kinds group still have in all special pigment and also do not show green more, so their plastid calls chromatophore especially or hold lubricious put oneself in another's position.

能进行光能无机营养一般藻类的细胞内除含有和绿色高等植物相同的光合色素外，有些类群还具有共非凡的色素而且也多不呈绿色，所以它们的质体特称为色素体或载色体。藻类的营养方式也是多种多样的。例如有些低等的单细胞藻类，在一定的条件下也能进行有机光能营养。

In the austenitic form elements - nickel chrome steel iron - into the process, with the increase of the formation and composition of nickel austenitic will gradually increase until all the ferrite structure have been transformed austenitic structure, thus formed the 300 series stainless steel.

在把奥氏体形成元素-镍加入到铁-铬不锈钢的过程中，随着镍成分增加，形成的奥氏体也会逐渐增加，直至所有的铁素体结构都被转变为奥氏体结构，这样就形成了300系列不锈钢。

The valence electron structure of medium chrome cast iron matrix is set up and the effect of Si on medium-temperature phase transformation is analyzed by using empirical electron theory of solids and molecules.

此文建立了290Cr8Si2中铬铸铁基体的价电子结构，运用固体与分子经验电子理论分析了中铬铸铁中Si对铸铁中温相变的影响，分析和实验结果表明，290Cr8Si2中铬铸铁基体含C、Cr、Si的-γFe晶胞中，C原子与Si原子的结合力强于C原子与Cr原子的结合力，中铬铸铁中较高的含Si量降低了铸铁基体的含Cr量，进而降低了中铬铸铁的淬透性。

The investigation of the catalytic activity and stereoselectivity of ligand 10 was also carried out under another standard set of K〓Fe 〓 conditions (〓/ligand/substrate=0.002: 0.01: 1). The AD reaction of seven olefins gave corresponding diols in 72～99% yield (except for ethyl cinnamate, 48%) and 91～99% ees, which was comparable to those obtained from the reactions using the commercial ligand 〓PHAL.

将单季铵盐手性配体10用于AD反应的另一个催化体系〓BuOH-H〓O/K〓Fe〓中考察其催化活性和立体选择性，在七种烯烃的AD反应中，〓、配体与底物的摩尔比为0.002：0.01：1时，化学产率为72～99％（肉桂酸乙酯除外，为48％），ee值为91～99.9％，与商品配体〓PHAL的催化结果相当。

ZL03 2 354312.The innovations include: automatic self-closing and reliably sealed valve structure: the design of duplex valve clack with pilot valve to tackle the problem of reverse seal structured valve being difficult to be opened; an automatic drain control device to automatically drain the remaining water from the hydrant; protective plate provided between the hydrant body and the valve block to serve as a connection between the hydrant body and the valve block, which is the first one to be damaged when the ground hydrant is clashed, and prevent pulling-off of the whole above-ground part of the fire hydrant, so as to properly protect the main parts from any damage. The self-closing and reliably sealed valve now prevents drain of water, and only the damaged protective plate is needed to be replaced before immediate re-operation. Thus the repair work after clashing is very easy and simple.

其创新点为：具有能自动关闭并可靠密封的阀门结构：采用有先导阀复式结构阀瓣设计，解决反向密封结构阀门开启沉重费力的难题；设计自控排水装置，能自动排除栓体内余水；在栓体和阀体之间设计撞裂板，它既起到连接栓体和阀体的中介作用，又可在地上消火栓被撞击时率先破裂毁坏，并使露出地面的栓体不见整体脱落，有效保护各主体部件的完好无损，而此时阀门的自闭式结构可靠密封阀门阻止水源外泄，修复时只需更换损坏的撞裂板即可立即复位投入使用，使被撞后的修复工作变得十分轻松简便。

In addition, using RT-PCR to detect expression of centrin homogene during Urechis unicinctus spermatid deferentiation and early embryonic development. The result revealed that (1) expression of HsCEN1 homogene is present during spermatid defferentiation including spermtid and sperm, but not in adult tissues including body wall tissue,intestinal mucous memberane cells and cell in coelom succus;(2) expression of HsCEN1 homogene is not present in unfertilized oocytes but present in that of released polar bodies after fertilization and parthenogenesis oocytes treated with A23187;(3) expression of HsCEN1 homogene is present during early embryonic development including two-cell stage,multicell stage,gastrula to trochophora.

我们还用RT-PCR方法检测了Centrin同源基因在单环刺螠精子分化过程和早期胚胎发育过程的表达，结果显示：在单环刺螠精子发生过程中的精细胞、精子团、精子中都有表达，而在成体的体壁组织、消化道组织、体腔球中则没有表达；在未受精卵中没有表达，而在受精后释放极体的受精卵和经A23187孤雌激活的卵中则有表达；在单环刺螠的早期发育过程——二细胞胚胎、多细胞胚胎、原肠胚、早期担轮幼虫——中都有表达。

This type of coevolution processes can be very useful in searching the global qusi-optimal solutions of complex problems.

Water is filled into 1/3-2/3 of underground solution cave, and light type nuclear fusion body is put into the cave. Igniting the nuclear fusion body make water reach water vapour state in high temperature and high pressure 300-400 deg.C and 30-40Mpa, which drives rotation of turbo generator to generate electricity. With power being done, exhaust steam is condensed in condensator. Then, igniting the nuclear fusion body is carried out in another solution cave.

一种利用热核聚变能发电的方法，它包括以下步骤：在地下熔洞中注入占该熔洞1/3～2/3的水，并在该熔洞水中放入轻核聚变弹体，引爆该弹体后使熔洞中的水达到300～400℃、30～40Mpa的高温高压水蒸汽状态，并使之驱动汽轮发电机旋转发电，作功后的乏汽经冷凝器冷凝；在另一熔洞水中再引爆一轻核聚变弹体，使该熔洞中的水达到300～400℃、30～40Mpa的高温高压水蒸汽状态，并驱动汽轮发电机旋转发电。
