A large range of IRZ and intense fluctuating velocity area around the boundary of IRZ is measured and thought to be important to keep the excellent ignition and combustion characters of the new kind swirl burner. Together with temperature trace method, different structure and operation parameter of the burner are studied in this paper about their effects on turbulent and mixing characters of swirling jet. The structure variation includes different blade angle, use of central gear shape baffle, variable outer length and angle of lean primary air outlet, use of wedge outlet of lean primary air.

The unoperated sides of the treated animals also served as controls. Six normal rats were treated as normal control group. Three different siRNA plasmid solution containing RC2-Ⅰ, MAFbx-Ⅱ, CON (50μl , 0.8μg/μl)was injected and transfected by electroporation as methods mentioned above, respectively. The changes of RC2 and MAFbx mRNA levels and RC2 protein levels after 3 days were determined by real-time quantitative PCR and Western blot, respectively. On postoperative 2, 3 and 4 weeks, the rate of wet muscle weight preservation, mean diameter of muscle fiber and mean cross-section area of muscle fiber and muscle protein content were checked and then compared between group CON and group RC2 or group MAFbx, respectively. The differences between groups were analyzed by one-way ANOVA. Ultrastructural changes of muscle fiber were observed at 2, 3, 4 weeks postoperation.Results GFP plasmid was efficiently deliverd into muscle by electroporation and robust GFP expression in muscle could be observed more than three weeks. Histology shows that injected plasmid DNA diffuses extensively in muscle tissue.

METHODS From January 1998 to February 2001, 4 ml of sodium hyaluronate injection was injected into the knee joint of the 134 cases at the end of arthroscope operation, or the 91 cases undergoing open operation of the knee at the time when the drain tube was removed. Five days after operation, the hydrarthrosis was removed and 2 ml of sodium hyaluronate was injected into the knee joint. According to the patient's condition, injection of sodium hyaluronate was performed once a week for several weeks. Clinical evaluation was made by evaluating pain visual analog scale and painless range of movement of the joint at every definite point of time.

The authors think that the magmas of the intermediate-acid volcanic rocks were derived from basaltic magmas of the lower crust and are mixed magmas produced by the increase of geothermal gradients due to diapiric injection of basaltic magmas and partial melting of intermediate-basic metamorphic igneous rocks in the lower crust,and that they resulted from a series of tectonomagmatic activities that took place when the closing of the Mongolian-Okhotsk sea trough and continent-continent collision caused crustal thickening and brought about the formation of the Hinggan-Mongolian orogenic belt in the process of oblique subduction of the Paleo-Pacific plate beneath the Siberian plate.

中文摘要：通过对大兴安岭北段晚侏罗世吉祥峰组中酸性火山岩的岩石地球化学研究，发现其中存在高Sr低Y型火山岩，即文献上所称的埃达克质岩，笔者认为中酸性火山岩的岩浆起源于下地壳玄武质岩浆，为玄武质岩浆底辟上侵引起地热梯度增加、下地壳中基性变质火成岩石部分熔融的之混合岩浆，是古太平洋板块向西伯利亚板块斜向俯冲过程中，蒙古鄂霍次克海槽封闭，陆壳碰撞使地壳加厚，形成兴蒙造山带时所引起的一系列构造岩浆活动。

In the present study, we collected cumulus cells oocyte complex from ovaries of two different strain mice. The cumulusenclosed oocytes were cultured for 6 h in MEM supplemented with growth factor and FSH. The meiotic maturation of these oocytes has progressed to pro-metaphse Ⅰ stage and the condensed chromosomes are visible under DIC microscope, metaphase Ⅰ spindle even can be detected under Polscope. The metaphase Ⅰ spindles of oocytes were exchanged under such microscopes. After electric stimuli, 91. 6% and 91. 6% karyoplasts-cytoplasm pairs were fused respectively. The resulting oocytes were cultured further in MEM and over 80% of oocytes released the first polar body. 79% and 77% of oocytes formed two pronuclei after in vitro fertilization and the embryos were cultured in KSOM supplemented with amino acids. Over 60% of embryos developed to blastocyst stage.
