不受阻碍

The substituted half-sandwich titaconece with bulky alkoxyl group [CpTiC1〓 or CpTi 〓] or indene ring can not be fluorinated by BF〓·Et〓O under the selected condition, but still coordinates with the BF〓, this coordination then enhances the steric effect that stabilizes the precursor and hinders the reduction of the Ti to the Ti species, reflected in the decrease in polymerization activity.

但是这个转化受主催化剂分子的空间位阻和聚合反应温度的影响，当主催化剂为大位阻的烷氧基取代茂钛络合物或茚钛络合物时，在一般的聚合温度下BF〓不能对它们进行氟化，但可以和其中的OR配位，这种配位进一步加剧了空间位阻，从而阻碍了活性中心的形成，导致催化活性的下降。

Under the press of high content of calcium and magnesium in rocks, alkaline karst soil have low available forms of phosphorus and potassium in macroelement, high calcium and magnesium in middle element, enough necessary microelement except available form of boron, and more than 1 mg/kg cadmium of toxic element.

中药材金银花富集钙、镁、磷、钾、铜、锌等元素，对镉吸收低，适宜在岩溶地区种植。马尾松纯林受土壤低有效磷、钾和硼，高有效锌和钙的阻碍以及高镉的轻微毒害为不适宜树种。

The results show that the dissolution of Ag was restrained by forming of a silver suboxide film on the surface under low oxidant concentration and atmospheric pressure conditions (e.g., in NH_3-O_2-H_2O system); when the concentration of oxidant was high enough (e.g., in NH_3-H_2O_2-H_2O system), the leaching process was carried out without forming of the film and the rate of dissolution of Ag was controlled by a step of mass transfer.

结果表明，在常压下氧化剂浓度低时(如在NH_3-O_2体系中)，浸取反应受在Ag表面上生成的氧化物膜所阻碍；而在浓度足够高的氧化剂时(如在NH_3-H_2O_2体系中)，浸取过程可在不生成氧化物膜的条件下进行，此时Ag的溶解速度受传质步骤控制。

Part three mainly explores therelationship between risk bearing and concerning systems,putting forward opinions such as that iffault guarantee liability of goods is not the obstacle of the transference of risk bearing,transference of risk bearing is not the obstacle of fault guarantee liability of goods;if the sellerdelivers the object to the delivery place according to the contract or the legal provisions while thebuyer does't accept the goods according to the agreement,or the goal of contract can't beachieved because that the object's quanlity can meet the requirement of the contract,the buyerrefuses to accept the object or rescinds the contract,the occupant has the obligation to keep it ingood condition and prevent the enlargement of damage or ease the damage according to theprinciple of good faith.

第二节，主要探讨了风险负担与相关制度的关系。如认为物的瑕疵担保责任不阻碍风险负担的移转，风险负担的移转亦不排斥物的瑕疵担保责任；在出卖人按照约定或依照法律的规定将标的物置于交货地点而买受人违反约定没有收取时，或者因标的物质量不符合质量要求，致使不能实现合同目的的，买受人拒绝接受标的物或解除合同的，货物的占有者或代为保管者基于诚实信用的原则应尽妥善保管的义务，防止损害的扩大或减轻损害。
