  8. Although economic and population specialists and scholars both in abroad and at home have made extreme progress on research the question of rural labor since they studied it very long ago, as far as china is concerned, based on the following three aspects, firstly, the national condition of our country determined that the foreign theory such as lewis theory might instruct us but we ca n ' t use these theories without rectification ; secondly, in china, our research about this question prefer the qualitative analysis to the quantitative analysis ; thirdly, the research on the labor utilization and shift in this specific area, that is, in the mountainous rural area which covers 69 % of our mainland and occupies 56 % of population is absolutely scarce in present ? to make up for the three deficiencies, this paper selects the econometrics analysis, uses investigation data and by virtue of tsp software, establishes a model where shift labor is the dependent variable and the citilization ratio, industrial structure, the income gap between city and country, the rural infrastructure construction, the labor ' s aptitude and the population ' s natural growth ratio are the variableso through economic, statistical and econometrical test, the conclusion is attained : the income gap between city and country and the citilization ratio are the two most important fectors which affect the labor ' s utilization and shift in mountainous rural area -, the rural infrastructure construction and the labor ' s aptitude are the two relative important factors which affect the labor ' s utilization and shift in mountainous rural area while the rural industrial structure and the population ' s natural growth ratio are the two least important factors according to this, this paper puts forward several suggestions that the income gap between city and country, citilization ratio, rural education, rural industrial structure and agricultural mechanization should be carefully treated with on studying the question of labor utilization and shift in mountainous rural area. finally, this paper points to several suspending problems about this research in order to get the concern of specialist and scholars

    盡管國內外經濟和人口學方面的專家與學者很早就開始了對農村勞動力問題的研究並取得了極大的進展，但是，我國在研究農村勞動力問題時，基於三點：其一，我國國情決定了國外的理論例如劉易斯理論，雖然對研究我國的農村勞動力問題具有指導意義，但卻不能照搬這些理論；其二，從國內看，我國對該問題的研究重視定性分析而定量分析明顯不足；其三，缺乏對我國占國土面積69 、人口56的山區農村這一特殊區域內的勞動力開發利用及轉移的專門性研究。為了彌補這三個缺憾，論文採用經濟計量學的數量分析方法，利用實際調查資料，藉助tsp軟體，建立了以外出勞動力數量為被解釋變量，城市化率、農村產業結構、城鄉收入差距、農村社會基礎設施建設、農村勞動力素質以及人口自然增長率六個變量為解釋變量的模型，通過對該模型進行經濟學、統計學、經濟計量學三個方面的檢驗，得出如下結果：城鄉收入差距和城市化率是影響山區農村勞動力開發利用及轉移的最重要的兩個因素；農村社會基礎設施建設和農村勞動力素質是較為重要的兩個影響因素；而農村產業結構和人口自然增長率相對來說是較不顯著的影響因素。據此，本文提出了在研究山區農村勞動力開發利用及轉移問題時，應慎重對待城鄉收入差距、城市化水平、農村勞動力素質、農村產業結構、農業機械化五個問題。

  10. It is not many scholars to clearly prove the opinion of shifting the burden of proof, on the contrary the contradictory scholars are more prominent, for example the vice professor of southwest politics and law university, chengang, wuyue who translates and introduces the burden of proof of germany, because them there are more and more people support the opposite opinion, while in the draft of " civil evidence code ", the traditional idea win, in this draft the legislator abides by the present justice and our country ' s native circumstance, they made an scientific choice, of course, the burden of proof will directly influence the party " s possibility of losing the lawsuit, while the regulation of shifting the burden of proof increases the plaintiff ' s opportunity to win a lawsuit. to explain what is the shifting of burden of proof, the paper use the civil law as the example to point out the " reverse " is not entirly relieve the plaintiff s obligation of producing evidence, but in certain extent and in certain range make the defendant bear the burden of producing those proofs from the reverse way, which are originally beard by the plaintiff. in the three proceeding law, shifting the burden of proof have some differences, but the interior spirits are coincident - for the values of social justice and the legal reason

    論證舉證責任倒置的學者觀點明確並且論證十分充分的不多，相反卻是對此著書立說予以反駁的學者較為突出，如西南政法大學的副教授陳則博士，翻譯並介紹德國證明責任學說的吳越先生均是目前國內對舉證責任倒置持否定態度的代表人物，由於他們的推動使得國內持此說的人越來越多，但在《民事證據法（草案） 》的擬定過程中，並未采責任倒置的地位，這樣的立法選擇是建立在對我國法律實現的本土環境客觀認識的基礎上的科學選擇，誠然，舉證責任的分配直接影響到當事人在訴訟中的敗訴風險，而「倒置」規則的設計，則在此問題上增加了原告勝訴的籌碼，在理解何為舉證責任倒置時，本文著重以民事法為主線，指出這種「倒置」並非全部免除原告的證明責任，而是在一定范圍與一定程度上將通常應由原告負擔的舉證責任轉由被告從反方面承擔，舉證責任倒置在三大訴訟法中所體現的具體情形有所差異，但它們的內在精神是一致的?法律的理性與社會公平價值，在民事訴訟中舉證責任倒置的情形，一般總是將其局限於特殊侵權情形，而忽略了民事合同違約責任的訴訟中的原告也無須對被告應承擔違約責任的所有要件，對被告主觀上的過錯實行推定，若被告予以否定則應對其無過錯的證據舉證，在設置舉證責任倒置的規則時，從各國的立法經驗與法的內在價值要求可以總結出以下幾個原則:程序法與實體法結合原則，公平原則，訴訟經濟原則，保護弱者原則等，基於此完善舉證責任倒置的規則時首先應肯定舉證責任倒置的概念，其次立法應避免求大求全，再次要配合實體法的發展，最後還可以在司法領域嘗試判例的指導意義。
  11. The author believes that government should establish regional economic development strategy from the angle of the whole country and build the regional economic relationship with internal and external circle. the establishment of regional strategy should be guided by the view of market. the government should forcefully propel the establish of central and western regions " factors markets, nature the central region of economic development, enhance the reform strength in central and western regions, deepen the open to the outside, build the growth foundations recycling around the hi gh technology, develop the rural and town enterprises, propel the economic connection and cooperation between the central and western region, and prompt the fundamental transform of the economic system and the way of economic growth in the central and western region

According to the structure characteristics and motion rules of the new type nursing robot, the close loop control system of this new type nursing robot is designed and made with the virtual instrument developing software labwindows / cvi, mcu, piezoelectric ultrasonic motor and high precision optical incremental encoder, which can make the robot reset and rotate by the predefined tracks. at the same time, in order to make the nursing robots used more widely where intensity, precision and price are not high, another control system is designed with the step motor, virtual instrument developing software labwindows / cvi, multi - function daq card pci1711, linear power amplifier. in order to use the nursing robots in acupuncture therapy, a simple finger is designed

    在對其結構特點和運動規律分析的基礎上，本文以虛擬儀器編程語言labwindows / cvi為軟體開發工具，以單片機為控制核心，以超聲電機為驅動元件，以高精度光電編碼器作為速度和角位移檢測裝置，實現了機械臂的復位以及預定軌跡的閉環控制系統的開發;同時為適應一些強度不大、精度要求不高的應用場合，也為降低成本，簡化控制裝置，推動新型護理機械臂短期內應用推廣的需要，以目前應用較為廣泛、控制技術較為成熟的步進電機為驅動元件，用labwindows / cvi開發環境、 pci1711數據採集卡以及線性功率放大器開發了一套控制系統，實現了手臂的復位、勻速運動以及預定軌跡的控制系統;為推廣護理機器人在針灸理療中應用，設計了簡單的手指機構並利用labwindows / cvi開發環境，以及智能材料驅動器? ?層疊式壓電驅動器，進行了手指的抓取以及對驅動對象的轉動控制。
