无法研究的

Study discussant William Wijns, MD, codirector of the Cardiovascular Center at OLV Ziekenhuis in Aalst, Belgium, cautioned colleagues not to abandon thrombolytics altogether."While PCI is the treatment of choice, reperfusion therapy using lytic agents is indicated when PCI is not available. This has not been jeopardized," he said.

参与研究讨论的比利时阿斯特城列肯赫斯区心血管疾病研究中心副主任William Wijns医学博士警告同业，不要断然放弃溶解血栓剂的使用；他表示，必须使用PCI却无法即时获取此项疗法时，就必须要使用溶血剂作再灌注治疗，这种治疗方式本身不曾造成危害。

It was found that the low cycle fatigue character has close internal relations with the high cycle fatigue character. In the research of high cycle fatigue of concrete, the test means of cyclic loading between the set constant of force or stress has been extensively used. But this kind of test means can't be used in studying the behavior of concrete low cycle fatigue under large strain.

在研究中发现低周疲劳特征与高周疲劳特征有着密切的内在联系，但高周疲劳问题研究中使用的是在设定的力或应力的上下界限之间重复受力的试验方法，这种方法已无法用于混凝土高应变低周疲劳性能的试验研究。

Hereinto, the study of Multi-Agent simulation of economies based on the complex adaptive system theory is an important research branch of the complexity of economy.

首先，由于现实经济中涉及的因素众多，相互关系复杂，给数学方法的运用带来了一定困难；其次，传统方法没有很好地解决经济系统的层次性结构问题，因此，无法对不同层次的特性差异给予一个整体性的解释，也就产生了宏观、微观相互脱节的理论体系上的缺陷；再次，传统经济理论对现实经济普遍存在的信息不完备与不确定性尚不能给予系统的解释；最后，传统经济中以观测数据为基础的经验主义的研究方法，无法深入了解经济的微观运行过程，从而降低了理论对现实的解释与预测能力。

The human cartilages are composed of chondrocyte and extracellular matrix , the form of chondrocytes are hypertrophy and the quantity are less; the ECM of cartilage are compised of type Ⅱ collagen and proteoglycan. Articular cartilages are all hyaline with little fibers. Trauma and arthritis are the main cause of cartilage injury, the ommilayer injury ofcartilage can be recovered by marrow, but because of without stimulation mechanism, the new tissues are merely fibrocartilages, they can not be coincide with hyaline cartilage in menchanics; the purely damage of articular cartilage can not stimulate chondrocyte to regenerate because of without blood circulation, thus, the plerosis of articular catilage can not depend on the proliferation of local chondrocyte. Ever since, people tried their best to find a way to reconstruct articular cartilage.

Research on rhizosphere microbe is essential for microbial ecology and industrial biotechnology. However, the inability of culturing most rhizosphere microorganisms (around 99%) in the laboratory obviates the research progress.

根际微生物研究对微生物生态学和工业生物技术开发均十分重要，妨碍其研究进展的主要原因是99%的根际微生物物种在实验室中无法成功培养。

The difficulty in controlling the different parameters (metabolic, vascular, infectious, and foot off-loading) involved in the evolution of the diabetic foot and the lack of prospective randomized studies on the effect of HBO on this pathophysiological condition make it difficult to recognize HBO as an incontrovertible treatment.

法国斯特拉斯堡大学医院的Laurence Kessler博士表示，之前已经有研究提议HBO可以作为糖尿病患者足部溃疡的辅助治疗，因为它可以改善复杂的痊愈过程，控制糖尿病足部溃疡发展之不同参数（代谢、血管、感染和脚的负重）的困难点及缺乏HBO效果的预期性随机化研究，使得研究人员无法证实HBO是一种有效的治疗方式。

The study attempts to discern, by focusing on Taipei Dihua Street restoration and refurnishing petition cases as the study subject, why the "Taipei Dadaocheng Historic Zone" project, since its initial launching to this date, has failed to avert the general public's negative views that Dihua Street remains outdated, chaotic and inconvenient.

本研究以台北市迪化街申请修复与新建的申请案为研究对象，试图厘清为何「台北市大稻埕历史风貌特定专用区」计画施行至今至今，仍无法更新社会大众对迪化街『落后』、『凌乱』与『不便利』的负面印象。

Through relevant researches, the most commonly adopted way to establish visual beauty anticipation model is Scenic Beauty Estimation, which is a psychophysical paradigm. However, due to the fact that this model does not consider the ecological vegetable when selecting factors, it is not adoptable for the purposes of this thesis. Moreover, the application of the "multiple linear regression analysis" does not effectively show the relationship between the ecology and aesthesis of the vegetable.

经由相关研究得知，建立植栽之景观美质预测模型，最常运用心理物理模式中的景观美质评估法，不过其因子的选定并非以植栽之生态性为考量因素，与本研究希望藉由植栽之生态性与景观美质之定量相关建立预测模式不符；另外应用多元线性回归分析法，并无法有效反应上述两者之关系。

Kempers' study , the more layers the mesh screen type had, its resistance against gravity was higher, but its heat resistance and flow resistance were comparatively augmented. As mentioned in the preceding paragraph, it is extremely difficult for a single micro structure based on any of the three types to possess both low flow resistance and strong capillary force. Faced with this fact, the researchers have tried to mix the three micro structures in Table 2 into as many combinations as possible so that a composite micro structure with low flow resistance and great capillary force may be fabricated. After a thorough analysis, the groove combined with sintered metal or mesh screen has been found to be a better alternative. However, the groove combined with sintered metal will raise the flow resistance of the channel, and the aluminum substrate employed in this research cannot be sintered into a micro structure. As a result, the groove combined with mesh screen is finally chosen as the composite structure to enhance its capillary force and at the same time maintain its high permeability. In this way, the heat pipe will not fail due to the working angles.

Kempers 的研究当中提到，当网格结构越多层时，其对抗重力的能力也越强，但相对的其热阻以及流阻也越高，就如同前段所述，我们很难在单一结构当中找出一流阻低且毛细力之微结构；因此本研究便以表2中之三种微结构进行组合，找出一低流阻且毛细力强之复合式结构，经分析发现，沟槽搭配烧结以及沟槽搭配网格为较佳之组合方式，但由于烧结搭沟槽构造将会提高流道之流阻，且本研究使用铝做为基材，并无法使用烧结最为其微结构，故将采用网格搭配沟槽之复合式结构提高结构的毛细力，并维持沟槽结构的高渗透性，解决因角度造成热管失效的问题。

For statistical analyses, A mixed model ANOVA was used to compare the differences of the changes of bilateral malleoli distance from quiet stance to deep squat among three different conditions.

本研究之研究对象为健康成年人，或许是无法达到统计差异的主因，未来将进行胫腓联合关节伤害者的限制效应。
