To improve the efficiency of Oxalis triangularis purpurea breeding, this study is done by leaf explant. 0.5 mg/L 6-BA and 0.5 mg/L NAA are added to the culture based on the last study. KT and 2,4-D concentrations impact on Oxalis triangularis purpurea regeneration system by "one-step method" are further studied.

The results showed that 2,4 D had promotive effects on the growth of pavlova viridis, especially in the early stage of culture, and the optimum mass concentration was 0.1 mg/L. 6 BA had lethal effect on pavlova viridis, and the lowest lethal mass concentration was 1.0 mg/ L.

结果表明，在试验浓度范围内，2 ，4— D对绿色巴夫藻生长的影响在培养早期比后期明显，最适浓度为 0 。1 m g/L ；6-BA质量浓度≥ 1 mg/L时对绿色巴夫藻有致死作用，质量浓度为 0 。1～ 0 。8mg/L时，对绿色巴夫藻的生长有促进作用，促进生长的最适质量浓度为 0 。5mg/L。

Study on the lithology and petrology (fine-grained cold-quenching ring of the enclaves, the reverse vein, the complex enclaves, the plagioclase phenocryst from both host rock and enclaves that is consist on the crystal form, composition and light, et al.), petrogeochemistry (Y/Nb=2.77～6.82, La/Nb=0.91～4.33, Ba/Nb=0.13～37.86, et al.), Sr and Nd isotope most ISr between 0.7031～0.7041,εNd(t=5.2～7.1 and LA-ICP-MS zircon U-Pb dating (the host rock age is 311±12Ma, and enclaves is 306±7Ma), believe the Huangyangshan pluton is crust-mantle hybrid genesis.

通过岩石学和岩相学（包体细粒淬冷边，反向脉，复合包体以及寄主岩石和包体中斜长石斑晶在形态、成分、光性上的一致性等），岩石地球化学（Y/Nb=2.77～6.82，La/Nb=0.91～4.33，Ba/Nb=0.13～37.86等），Sr和Nd同位素（ISr多数在0.7031～0.7041，εNd在5.2～7.1之间）以及LA-ICP-MS锆石U-Pb测年（寄主岩石为311±12Ma，包体为306±7Ma）综合研究认为黄羊山花岗岩是壳-幔源岩浆混合成因的。

Of all tested plant growth substances, IBA, BA and ABA can promote the development of litchi pistil, while GA has no obvious influence on litchi pistillate and staminate development, putrescine precursor—arginine is helpful to staminate development.

在所试的植物生长物质中，IBA、BA和ABA对荔枝的雌蕊发育具有促进效应；GA对雌雄蕊的发育没有显著影响。腐胺的前体—精氨酸有利于雄蕊的发育。

BA l00ppm application did not descend to the node number to first flower bud, but had earlier flower formation due to shorter plastochron.

BA 100ppm并未降低花芽形成节位，但因早期（前4周）叶间期加速，故花芽形成日期提早，然效果不如paclobutrazol。

We obtained the infrared reflection spectra of Pr〓Y〓 Ba〓Cu〓O〓 system for the first time, in which the existence of Pr〓 is confirmed and found the reason, which the superconductivity descends along the increasing of the content of praseodymium, should be the great decrease of the carrier density.

我们首次对Pr〓Y〓-〓Ba〓Cu〓O〓进行了系统的红外光谱研究，证明了Pr的价态接近于+4，有效地解释了该体系随Pr含量增加超导性减弱的原因，在于载流子极大减弱。

The geochemical characteristics of basic to intermediate-basic igneous rocks indicate that they belong to a tholeiite suite. Their chondrite-normalized REE patterns are of nearly flat and slightly LREE-enriched type, and their primitive mantle-normalized and MORB-normalized trace element spidergrams are generally similar; the LILEs Cs, Ba, Sr, Th and U are enriched, while Rb and K and the HFSEs Nb, P, Zr, Sm, Ti and Y are depleted. All these show comagmatic evolutionary and genetic characteristics.

基性—中基性岩浆岩的地球化学特征表明其属于拉斑玄武岩系列，稀土元素分布型式呈REE近平坦型—LREE轻微富集型，微量元素原始地幔标准化的蛛网图和MORB标准化蛛网图上的分布型式总体很相似，富集大离子亲石元素Cs，Ba，Sr，Th，U而相对亏损Rb，K和高场强元素Nb，P，Zr， Sm，Ti和Y，显示同源岩浆演化成因特征。

In a word,it is more credible to use Mg/Ca ratio as climate psychrometer which has less external influence and it is questionable to use Sr/Ca and Ba/Ca ratios as one climate proxy because they are sensitive to many factors just like vegetation,soil microbe activity.

总体来看，石笋中Mg/Ca与Ba/Ca值的相关性很弱，可以认为分别受到降水和土壤微生物作用的影响，而Sr/Ca比值却可以与两者同时保持一定的正相关关系，表明其至少受到以上两种因素共同制约。

Effects of mannitol and 6 BA on the rice cell redifferentiation,activities of peroxidase and IAA oxidase were investigated.

研究了甘露醇和 6- BA处理对水稻悬浮细胞再分化、过氧化物酶及 IAA氧化酶的影响。

Liquid culture experiment,TDZ were produced more shoots than BA、kinetin ,but shoot were difficult growth into plantlet,and produced shoot redifferentiation form rhizome.

液体培养试验中，以TDZ所形成的芽数较BA、kinetin多，但是其芽体不易生长为幼苗，而逆分化为根茎。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.
