The RGCMSplants in RGCMS-117A or S45A were complete male sterile at the bothtemperature conditions,and there was no pollen sac differentiation at thehigher temperature condition and there were 1-3 pollen sacs in each anther atthe lower temperature condition,but the anther development was inhibited atthe stage of microspore.

表现核质不育的植株，在高温条件下表现彻底波里马细胞质雄性不育，无花粉囊分化；在低温条件下，也表现彻底雄性不育，具核、质不育的共同特点，每个花药可分化出1-3个花粉囊，但无可育花粉，其雄性败育时期和特点与S45A和117A相同。

As a precursive work of polymerization directly from vesicles, a polymerizable surfactant, allyl dodecyl dimethylammonium bromide was synthesized, and spontaneous stable vesicles were formed from aqueous solutions of ADDB and sodium dodecyl sulfonate in equimolar composition.

作为可聚合囊泡制备的前期基础工作，研究了一种可聚合的囊泡体系：1-丙烯基－2，2，二甲基－十二烷基溴化胺和ADDB与十二烷基磺酸钠的等摩尔比混合体系。

In central nervous system only a limited number of vesicles exist in the presynaptic terminals.

中枢神经系统突触前的神经末梢只有少量的突触囊泡存在，突触囊泡数目的多少和融合模式将影响突触传递的效率。

Using the Hprt gene as a positive control, our result suggested that both the testis tissue and the male embryos from which Sry transcription can be detected failed to yield any positive results of Xist. Female embryos at the pronucleus stage and 2-cell failed to produce any positive result of Sry and Xist too.

然后利用实验一确定的PCR条件，以Hprt为阳性对照，用巢式RT-PCR对小鼠早期胚胎进行Xist基因的转录分析，结果发现，转录Sry基因的睾丸组织以及雄性胚胎，从受精卵发育到囊胚的过程中，基本上不转录Xist基因；不转录Sry基因的雌性卵母细胞和雌性胚胎，从出现原核开始，到发育至2-细胞期的过程中，Xist基因一直不转录，但是，从4-细胞期开始，一直到孵化前囊胚阶段，雌性胚胎都转录Xist基因。

SP method was used to test MDV-gBAg in tissue paraffin sections of hearts, livers, spleens, lungs, kidneys, proventriculi, bursas, skins, and blood smears of MDV positive chickens, the results showed that the found ratios of liver, spleen, lung and skin were the highest (arrived at 100%), the ones of proventriculus and bursa were the second (arrived at 88.89%), the ones of kidney and heart were lower (33.33%, 22.22%, respectively).

用SP法检测阳性鸡心、肝、脾、肺、肾、腺胃、法氏囊及皮肤石蜡切片和全血涂片中的MDV-gBAg，以肝、脾、肺和皮肤的检出率为最高(达100%)，腺胃和法氏囊的次之(为88.89%)，肾和心的较低(分别为33.33%和22.22%)。

Those may be the structure for pyrenoid photosynthesis. The starch sheath embedded the pyrenoid. The pyrenoid could be divided into three types according to their structure.

并观察到蛋白核与叶绿体基质有多处联系，蛋白核内的类囊体发生膨大，并在莱茵藻蛋白核中观察到有数个类囊体堆积，这些细微结构功能还不清楚，可能与蛋白核行使光合功能有关。

In this paper,natural pyrethrum nano-capsule with a wall of the copolymer of styrene and methyl methactylate was prepared by means of microemulsion polymerization .

研究用微乳液聚合法制备以甲基丙烯酸甲酯和苯乙烯共聚体为囊壁，以天然除虫菊酯为囊芯的纳米胶囊。

Then replate them onto feeder layer culture system (containing leukemia inhibitory factor) in order to passage and expand. Subsequently we identified the expanding cells by alkaline phosphatase staining, karyotype analysis and the formation of embryoid body which are typical characteristics of ESCs.

以分离培养的细胞作为供体细胞，近交系C57BL/6J为受体囊胚供者，采用囊胚注射法构建嵌合胚，体外恢复培养后移植进动情期子宫中，结果生出了黑白杂合的嵌合鼠。

Using BG11 as base media,the toxic effects of heavy metal Cu2+on alga Microcystis aeruginosa were studied according to the change in growth,chlorophyll-a,photosynthesis release oxygen and respire exhaust oxygen of the M.aeruginosa under different Cu2+ concentrations in the experiment conditions.

以BG11为基础培养基研究了实验室条件下重金属Cu2+在不同质量浓度下对铜绿微囊藻的急性毒性效应。试验结果表明，Cu2+对藻类的抑制效应随Cu2+质量浓度的增加而增加：质量浓度为0.3~1.2 mg/L的Cu2+对铜绿微囊藻生长的抑制作用不显著，且48 h后出现藻细胞密度反弹现象，杀藻效果不理想。

Afterwards, releases were carried on by the sequences: suprapatellar bursa; medial and lateral channel; medial and lateral patellar retinaculum; patella/femoral joint; condyloid socket; medial and lateral chamber; adhesion between femoral and quadriceps.

方法］釆用膝前内、前外及骸骨内上、外上4个5~10mm切口，先松解、扩张髌上囊创造出进入关节镜的空间，依照髌上囊→内、外侧沟→髌骨内、外侧支持带→髌股关节→髁间窝→膝关节内侧室→外侧室→股骨与股四头肌之间的粘连顺序进行松解。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
