After treatment in M2〓 medium containing 3% sucrose, a swelling around the metaphase chromosomes could be easily found in perivitelline space and, moreover, the area of spindle, becoming transparent and taking a shape of"∞"and"O", could be well distinguished from other cytoplast.

在本研究中，采用含3％蔗糖的M2〓操作液（3SCOM）处理卵母细胞，可使纺缍体部分变为透明并呈"〓"或"O"形状，这样可使其明显区别于周围的细胞质。

The definiens and working principle of controllable pitch propeller are introduced, the characters of CPP mechanism are summarized, and three types of shipping are concluded, which is applicable to equip with controllable pitch propeller by compared with pitch propeller. The control system of CPP usually adopts PID control, but the parameter of PID controller is adjusted inconveniently so as not to receive favorable result, therefore, the CPP control system based on fuzzy and neural network control is proposed so that improving the control effect. The result shows that the system design is feasible and effective.

介绍了可调螺距螺旋桨的定义及工作原理，并归纳了可调螺距螺旋桨推进装置的工作特性及特点，通过与定距桨进行的对比分析，总结出适用于可调螺距螺旋桨的三类船舶；目前调距桨控制系统一般采用传统的PID 控制方法，但由于PID控制器的参数不便于调节，不能取得良好的控制效果，从而提出了基于模糊神经网络控制的调距桨控制系统的设计，以提高调距桨在各种工况下的控制效果，仿真试验结果表明了调距桨控制系统设计的合理性。

Use somatostatin after PD can restrain organism excrete diastase vera,and help anastomotic stoma to concrescent and decrease pancreatic leakage;pancreatic leakage should be treated by different grades,grade 1 can be cured by persistent drainage with somatostatin and nutritional support;grade 2 should be pay more energetic intervention.

PD后应用生长抑素持续泵入可以抑制胰酶的作用，使胰肠吻合口较好地愈合，从而有效地减少胰漏的发生；胰漏可进行分级治疗，Ⅰ级胰漏采用通畅引流为主，同时使用生长抑素和营养支持等治疗多可治愈，Ⅱ级胰漏需要积极治疗。

Using a large data set of 1 894 images,we examine whether the colorspace transformation can increase the compactness of skin distribution and the discriminability between skin and nonskin distributions in fourteen 3D colorspaces and fourteen 2D chrominance planes.

比较结果表明：(1)颜色空间的变换并不能改善肤色紧致性、肤色-非肤色可分辨性以及分类等性能，但RGB及线性变换空间却具有较好的类可分辨性和分类性能；(2)去除亮度信息将明显降低肤色和非肤色之间的可分辨性和分类性能；(3)Bayes决策下的3维SPM的分类性能是最优和空间无关的，而其余分类器则普遍存在类似的"空间偏好性"；(4)同时采用肤色和非肤色模型的分类器的分类性能优于仅使用肤色模型的分类性能。

Machinable bioactive glass-ceramics containing mica and fluorapatite were prepared by high-temperature melting. The glass-ceramics were analyzed by means of X-ray diffractometry, scanning electron microscopy with energy dispersive spectrometer and Fourier transform infrared reflection spectrometry. The bending strength, hardness and fracture toughness of the materials were measured.
