The results showed:(1) the cellule morphous and the disposition in chick embryo of PGCs were coincident no matter stained by PAS or HE staining, and HE staining could disclose the morphologic characteristics more clearly, exactly and completely;(2) genesis of blood island could be observed at the boundary of light and dark region of the extraembryonic blastoderm at about 26 hours;(3) both the blood vessel endothelium cells and free cells of the blood island were differentiated from PGCs. The generating of genuine yolk sac was at about 44-48 hours.

结果表明：①用经典的识别原生殖细胞的PAS染色方法与HE染色所观察到的PGC在鸡胚的分布及细胞形态基本一致，而HE染色较PAS法能更有助于清晰、完整、准确地识别PGC的细胞内部结构特征；②在孵化26小时的鸡胚胚外胚盘的明暗交界处可见血岛的发生，血岛发生的时间比真正的卵黄囊产生时间（大约44-48小时）要早很多；③血岛周围的血管内皮细胞与管腔中游离细胞都来自PGC。

The results revealed that a nano-fibrous matrix made of PHA materials had been formed through unique solution process, the nano-fibrous matrix is similar to the structure of collagen, which is the main component of extracellular matrix, and its average diameter of the fiber is ranged 80～350 nm.

同时，通过扫描电镜的检测发现了具有纳米纤维网状结构的PHA新型支架材料，这种通过溶剂处理法获得的PHA纳米纤维支架与细胞外基质的主要成份胶原蛋白的结构非常类似，它的纤维直径平均大小在80-350 nm 之间。

One is to calculate emissivity, the other is to get blackbody's energy. This software also put forward two new kinds of method for measuring temperature, self energy spectrum contrast and summit wavelength thermometry.

软件不仅完善了原设备的功能，同时研究开发了新的功能：进行辐射系数的计算和分析；标准黑体的能量计算；提出了两种新的测温方法——自能谱比较法和峰值波长测温法。

In this paper, the maximum likelihood algorithm with process and measurement noise for nonlinear continuous-discrete system given by Jategaonkar and Plaetschke is improved in two aspects: 1 to avoid the disadvantages of sensitivities computation by common finite-difference method, in which the perturbation sizes should be selected optionally, an improved finite-difference method with best perturbations, is presented. 2 to improve the numerical stability of Jategaonkar's algorithm, maximum likelihood algorithm with fast triangular square-root decomposition filter is given.

摘要对Jategaonkar等人给出的同时计及过程及观测噪声的非线性连续-离散系统的极大似然算法从两个方面进行了改进：1给出了计算灵敏度的最佳摄动有限差分算法，避免了普通有限差分法计算灵敏度矩阵时需人为选择参数摄动量大小而带来的缺点；2给出了具有快速三角化平方根滤波的极大似然算法，提高了原算法的数值稳定性。

The Application of Ultrasonic Wave to Medicative Abortion;2. Optical fiber ultrasonic wave monitoring based on Mach-Zehnder interferometer;3. In this paper,the extraction of grape seed proanthocyanidin using ultrasonic wave was studied.

对葡萄籽中原花青素的超声提取工艺进行了研究，在单因素实验和正交实验的基础上，得出超声波法提取葡萄籽原花青素的最佳工艺条件为：在40℃下，以料液比为30：1的40%乙醇溶液，用120W的超声功率对葡萄籽作用10min。

The results showed that plenty of the purified DPV virions were obtained after the cell lysate was condensed by 5-fold by ultrafiltration,and the concentrated DPV fluid was ultracentrifuged with 300g/L sucrose cushion method and 300-600g/kg sucrose density gradient centrifugation methods.

结果显示，用切向超滤法将病毒培养物浓缩为原体积的1/5后，再采用300g/L蔗糖垫底超速离心和300～600g/kg蔗糖密度梯度离心的方法进行纯化，可获得大量的纯化病毒粒子。

Next, Dr LaVan and his colleagues installed a protein called alpha-hemolysin into the protocell membrane. This functioned as a selective bridge, permitting the passage of positively charged sodium ions, but not negatively charged chloride ions.

接下来，拉文和他的同事们在原细胞的细胞膜中加入了一种叫阿尔法溶血素的蛋白质，这样就建立了一个选择性的通道——允许正极的钠离子通过，却阻止负极的氯离子。

The world is smaller than we think, say scientists who say their new measurements could force other researchers to rejig their calculations.

科学家们称，地球比我们原以为的要小，他们的新型测量法将迫使其他研究人员重新调整自己的测算法。
