A study on the anatomical structure and the barbloin's store place of Pulsatilla chinensis of different growth lengths by anatomy and barbloin histochemical localization shows that multicellular nodulos, secretory cavities and secretory ducts in phelloderm and secondary phloem are the primary place of the barbloin substances and the major structural characteristics, wide or narrow of the secretory ducts is related to the growth length, 4 to 5 years old reaches maximum.

利用解剖学和组织化学定位方法对不同生长龄白头翁根的解剖结构和皂苷的储藏场所进行了研究。结果表明：栓内层和次生韧皮部中的分泌细胞团、分泌腔和分泌道是白头翁根的主要结构特征，是皂苷类物质的主要贮存场所；而分泌腔和分泌道的数量及分泌道的宽窄与生长年限相关，4~5年生达到最大值。

On the basis of comparison of several algorithms of the calculation of unstable resonator"s mode. Fast Fourier transform method is chosen in this paper. The model of multi-layer distribution of gain is established. Sampling granularity in real space used in FFT, quotient of guard band and distance between subsections are made certain respectively. The convergence criterion of root-mean-square of plural y which is the quotient of the optical field"s distributions separated by one pass is established. Under the circs of multi-kind of distribution of gain and different measurement of distortion, the output optical field distribution is calculated.

在比较了各种计算腔模方法的基础上，根据角谱传播理论，选择FFT算法，建立谐振腔内多层增益分布模型，分别确定了FFT算法的空间采样间隔、保护带系数和分段计算的距离，选取光场往返一次之比的均方根值收敛准则，计算多种增益分布、不同镜面变形时的谐振腔输出光场分布，同时计算该光场的远场分布和传输有限距离之后的分布。

The septum (34) is further preferably configured to minimize or eliminate the negative pressure deflection normally associated with the withdrawal of the large diameter luer cannula (32) from an enclosed fluid filled lumen or chamber, by substantially isolating the lumen or chamber from the septum material displacement resultant from luer (30)insertion.

上述隔垫(34)的结构最好设计成能通过把空腔或腔室与因路厄氏连接器(30)插入后所造成的隔垫材料的移动隔离开来，以便减小或消除通常与大直径的路厄氏套管(32)的抽出联系在一起的，因负压而引起的变形。

The results show that the numbers of antennal sensillar on anttena at different stage of locust increase significantly, particularly sensillum basiconic and sensillum ceoloconica, in contrast, sensillum trichodea and chartica increase modestly.

结果表明，随着蝗虫龄期的增加，其触角各鞭节上的毛形、锥形、腔锥形和刺形感器数量也在不断增加，成虫期的锥形和腔锥形感器的数量为1龄的10倍左右，而毛形和刺形感器增加的数量为1龄期的5～6倍。

In order to improve the discrepancy of Ocarina, we used air window of whistle, air chamber of syringe together with the sound holes of Ocarina in making a sound adjustable Ocarina. The frequency spectrum was analyzed with computer sound fixing and ranging software and statistical software was employed to analyze the effects on pitch of area of sound hole and cubic of air chamber.

本研究为改良陶笛的缺失，利用哨子的气窗、针筒的气腔与陶笛的配孔式音孔结合，自创一种可调音的陶笛，并以电脑测音软体分析其频谱，利用统计分析其音孔面积与气腔体积对音高的影响。

The females incubated at 33 , their ovarium has powerful cortex, the germinal epithlium produce oocyte, its medulla degenerate into ovarian cavity. During sexual differentiation, mitochondria and smooth endoplasmic reticulum in cells of ovary increase in quantity, they disintegrate after sexual differentiation. There are a lot of big grana in cells of ovary before sexual differentiation, in the course of sexual differentiation the quantity of the big grana decrease, while small grana increase and peakafter sexual differentiation. The males incubation at 26 , cortices of their testes degenerate into a thin albuginea. Medulla are formed by testicular cords in which scatter spermatogonium.

33℃下孵化的小龟卵巢皮质发达，由原始生殖细胞产生卵原细胞，髓质退化成为卵巢腔，分化时卵巢细胞的超微结构显示线粒体和内质网的数量大大增加，它们在分化结束后解体，分化前细胞内有较多的大颗粒，在分化中大颗粒减少，小颗粒增多，在分化后小颗粒达到最多。26℃下孵化的小龟精巢皮质退化成为一层薄的白膜，髓质有许多睾丸管构成，管腔内有散落排列的精原细胞。

This thesis aimed to discuss an electromagnetic energy harvester. Motion of a fluid driven by a 30 Hz pulse pump is used to activate the electromagnetic energy harvester. The periodic motion of the fluid in the chamber causes a harmonic vertical deflection in the diaphragm on which a permanent magnet is attached. Subsequently, the vibration of this magnet induces an output voltage in a solenoid hanging above it.

中文摘要本文是探讨电磁式能量产生器的机构，此电磁式能量产生器的主要作动方式为藉由频率30Hz的脉冲马达驱动工作流体，使工作流体呈周期性的流动让帮浦腔体上致动薄膜产生周期性的上下往复运动，因此帮浦腔体内产生压力周期性的变化，在薄膜上永久磁铁的振动，使得螺旋线圈感应产生电压的输出。

The monotypic genus Macrovalsaria previously of uncertain taxonomic position turns out to be a member of Botryosphaeriales and seems to be related to Botryosphaeria. The placement of Neopeckia and of Dothidotthia is in Dothideales and Botryosphaeriales, respectively. The genera Plowrightia and Botryosphaeria as currently defined are not monophyletic. Species of Plowrightia appear to be associated with three genera, Dothidea, Neopeckia and Sydowia; those of Botryosphaeria tested are recognized as three groups.

结果还显示，座囊菌纲中分类地位不确定的属Macrovalsaria与Botryosphaeria的关系相对接近，应该归于葡萄座腔菌目；历史上分类地位有疑问的Neopeckia和Dothidotthia两个属处于不同的目中，前者属于座囊菌目，后者为葡萄座腔菌目的成员；座囊菌目的Plowrightia属并非单系群，该属成员分别与Dothidea、Neopeckia和Sydowia三个属聚类在一起；现行的Botryosphaeria属也非单系群，其属的概念有待澄清。
