An advantage of this method is that it can be applied when the covariance matrix of the invested projects is positive semi-definite.

Because of the individualistic standpoint of independent criticism which they adopt, it is difficult, if not impossible, to class together the representative writers who contributed to the literature of English deism as forming any one definite school, or to group together the positive teachings contained in their writings as any one systematic expression of a concordant philosophy.

由於对个人主义的立场独立的批评，而是采取了，它是困难的，即使不是不可能，也是工人阶级一起代表作家贡献的人文学英语自然神论作为形成任何一个明确的学校，或以小组一起积极教诲载他们的著作，作为任何一个有系统的表达，一个和谐的哲学。

Forty-eight hours after transfection, cells were harvested to determine luciferase activity by illuminometer. In the presence of RU486 a 40-fold maximum activation of the luciferase reporter gene was observed in cultured cells, whereas in the absence of RU486, no significant activation was observed. There was a positive correlation between the luciferase activation and RU486 concentration in a definite range. The results showed that the RU486-inducible regulatory vector was successfully constructed, which can be used to regulate the expression level of genes of interest in appropriate time by the inducer RU486. This inducible expression vector provides a platform for the research of gene regulation and gene therapy.

加入诱导剂RU486后，可以诱导表达荧光素酶，并在一定范围内两者呈正比，最高可以实现荧光素酶的40余倍的表达，而没有RU486时，几乎没有报告基因的表达，表明RU486诱导调控载体构建成功，可实现对目的基因的表达时间和表达水平的精确调控，为进一步的基因调控研究和和基因治疗提供了良好的工具。

Then A is positive semidefinite, negative definite and negative semidefinite.

则A是半正定，负定，半负定的。

Lastly,two sorts of splitting of definite positive matrix areformed,one of which is combined with U-transformation to put forward aniteration process for the sort of periodic structures.

构造了正定矩阵的两种分解格式，由此对于一类周期结构提出了一种酉变换迭代算法。

The dynamical system method is studied for solving operator equations of the first kind involving positive semi-definite operator with both operator and right-hand non- exact.

1引言动态系统方法是求解算子方程的一种有效方法，不但适用于适定的算子方程，而且适用于非线性和不适定的算子方程(见{1，2)。最近，A.G.Ramm在文！

RESULTS: In this series, 6 cases showed hematemesis, 2 showed melena and 5 showed both symptoms. All cases underwent endoscopic examination after being hospitalized; 11 cases received a positive diagnosis by endoscopy (11/13, 85%), the success rate of first endoscopic therapy was 91%(10/11), and 4 cases were treated by laparotomic surgery (4/13, 31%). Among them, definitive surgery was performed under the guidance of endoscopic hemoclipping in 2 patients who failed to be treated by endoscopy. In another 2 cases, diagnosis was missed by endoscopy and definite diagnosis was made only following exploratory operation or on the basis of pathology after the operation.

结果：13例患者临床表现为单纯呕血者6例，呕血伴黑便者5例，单纯黑便者2例，所有病例入院后均行内镜检查；其中11例经内镜确诊(11/13， 85%)，首次内镜治疗成功率为91%(10/11)。4例经手术治疗(4/13， 31%)，其中2例内镜治疗失败者在内镜钛夹指引下实施确定性手术，另2例内镜漏诊者靠手术探查或术后病理确诊。10例随访患者无1例复发。

Among the abnormal 71 patients, 67 (94.4%) patients had a shortening of the mean duration of motor unit action potential. 37 (52.1%) an increase in polyphasia, 19 (26.8%) a full interference pattern of reduced amplitude during maximal voluntary effort and 3 (4.2%) abnormal fibrillations and positive sharps. 19 (26.8%) definite "myopathic changes".

在EMG异常者中，出现平均运动单位电位时限缩短67例(94.4%)，多项波增多者37例(52.1%)，大力收缩时募集电位呈病理干扰相19例(26.8%)，异常自发电位3例(4.2%)，结果符合&肌源性损害&表现19例(26.8%)。

There were fewer positive cells in other groups. The change tendency from few to many is control 2, MP3→MP2, MP4→control 1, MP1 Conclusions 1. Methylprednisolone is a very potential anti-scar drug and can elevate successful rate of rabbit filtration. 2. Used in the way of cotton patch, MP has lower ocular toxicity. Samely, high concentration could be got topically. 3. In definite range, the activity of MP is concentration-dependent. In other words, the activity can be promoted with the increase of concentration. Total results considered, 100mg/ml MP group is identified to have the best effect of all MP groups in the experiment.

； 实3组与对2组脯间差异不显著（Pl.05），但与其它继间差异显著①＜0.05）；实2组和实4组间差异不显著，但与其它各组间差异显著（P＜0.05人结论1、甲基强的松龙是—种很有潜力的低毒的摊痕抑制剂，可提高兔B湖过阶术的成功率；人甲基强的松溉用术中湿片贴敷的方式，既减轻了毒副作用，又可以达到局部用药的高浓度，是一种值得推荐的给药方法；3、在一定范围内，甲强龙的作用与浓度呈正相关关系，本次实验以 100ined组效果最好。

Means the parent directory, so this command means to execute "toolchain.sh," which is in the current directory.

代表父目录，所以这个命令就是执行当前目录下的"toolchain.sh"。
