Can undoubtedly function well and provide insurance coverage to protect the risks of malpractice if there is either broad liability upon the hospital for these services as nondelegable duties or if liability is restricted to the independent contractor.

如果医院能对这些非其委任的服务负更广泛的责任，或是严格要求独立承包商的责任，我们的社会，无疑能够运作更良好，并对风险弊端提供保障，然依照目前不明确的制度，似乎无法有效运作，因此，The

Therefore,when the geology risk assessment is done,the geology risk index as effective thickness,porosity,permeability,abundance,exploration maturity,heterogeneity,exploration success ratio and gas combination are selected.Using the gray cluster method,this paper conducts the synthetic evaluation and research on geological risk taking 7 well blocks in a certain region as an example and according to geology risk assessment characteristics,which can quantize and display the quality of nonproducing reserves in each area.

为此，在对地质风险评价时，选取了有效厚度、孔隙度、渗透率、丰度、勘探成熟度、非均值性、勘探成功率、含气组合等8个地质风险指标，以某油田某地区的7个井区为例，结合地质风险评价的特点，运用灰色聚类法对其进行地质风险综合评价研究，使以各个区块为单元的未动用储量的优劣得以量化表现。

Nevertheless, the yield of pinacol was also strongly affected by the steric environment surrounding the carbonyl group. The pinacol coupling of aromatic aldehydes has been achieved with high yields under such a condition. However, the diastereose-lectivities of pinacols were not satisfying. Unfortunately, the ketones and most aliphatic aldehydes appeared inert under the same reaction conditions.

然而， 呐偶合反应的产率受到羰基周围环境的立体位阻影响较大，在此条件下，锌粉能有效地促进芳香族醛类化合物进行水相呐偶合反应，得到的呐醇产率高，但非对映异构体选择性差，而脂肪族醛类化合物得到的呐醇产率较低，在同样的条件下，酮类化合物不能顺利进行呐偶合反应。

The results showed that: the explants of strawberry leaves were rather sensitive to kanamycin, and the corresponding concentration of 20 mg/L could substantially inhibit the growth of non-transformed tisse and be used to screen the leaves of strawberry after transformation. Timentin at the concentration of 300 mg/L could be used to eliminate Agrobacterium tumefaciens and had minor impact on the growth of the explants. The preculture time of 2-4 days was beneficial to improve transformation frequency. Co-culture for 2-3 days not only had higher gus transient expression but also avoid the over-growth of agrobacterium. The bacterial concentration of OD(subscript 600nm) 0.4 was the best inoculum density and 10 minutes was the best inoculation time.

结果表明：草毒叶片外植体对卡那霉素较为敏感，适宜的筛选浓度为20mg/L，可明显抑制非转化组织的生长；300mg/L的羧吩青霉素可有效抑菌，对外植体生长影响也较小；预培养2-4d有利于转化；共培养2-3d有利于提高转化频率并避免了农杆菌的过度生长；OD(下标 600nm)值为0.4的菌液侵染10min效果最佳。
